Does our ordinary range hood have the function of purifying oil fumes?

Air purifying range hood is a combination of air purifier and range hood.

The combination of the two devices, one machine for two purposes, has two functions of air purification and smoke extraction kitchen appliances. The air purification range hood mainly includes two major functions: range smoke and air purification. Its range hood function is the same as that of the traditional range hood, which is mainly reflected in the opening of the range smoke function when cooking, which quickly extracts the waste burned by the stove and the harmful oil smoke produced by cooking, and discharges it outdoors to reduce kitchen pollution; The air purification function is mainly reflected in turning on the air purification function after cooking, and filtering out various harmful substances such as oil smoke that still remain in the kitchen through the air purification system, so as to achieve kitchen air purification and effectively reduce kitchen pollution.

Although they are all for the elimination of fumes, one is to directly exclude the fumes from the kitchen, but there is no impact on the fume purification and discharge, while the catering fume purifier is to purify the fumes and then discharge. Now there are environmental protection tests for catering fumes, and the use of catering fume purifiers can easily pass the catering fume detection. The use of a range hood does not help in the environmental protection detection of oil smoke, but only the role of removing oil smoke from the kitchen.

Now many people think that catering fume purifiers and range hoods are the same, or that the efficacy is the same. In fact, the catering fume purifier and the range hood are two completely different devices. The range hood is used to exhaust the oil fume, and the oil fume purifier is used to purify the oil fume.

One is just to remove the fumes from the kitchen, and the other is to purify the fumes and then remove the fumes from the kitchen. Moreover, the range hood is used in the kitchen at home, and the catering fume purifier is used in hotels, restaurants, canteens and corporate canteens.

Fill the room with clean air while making the best use of the space. The range hood is installed on the upper part of the stove, turns on the power supply of the range hood, drives the motor, makes the wind wheel rotate at high speed, forms a negative pressure area within a certain space above the stove, sucks the indoor oil smoke gas into the inside of the range hood, the oil smoke gas is filtered through the oil net, the first oil smoke is separated, and then enters the inside of the smoke duct of the smoke machine, the oil smoke gas is separated for the second time through the rotation of the impeller, the oil smoke in the wind cabinet is subjected to the action of centrifugal force, the oil mist condenses into oil droplets, and the oil cup is collected through the oil circuit. The purified flue gas is finally discharged along a fixed path. Many users in cooking, cabinet range hood only open a few minutes to turn off the range hood, this can not play its role, the correct way to use is as long as the beginning of cooking should be opened, until the whole cooking is over and then after 5 6 minutes, can be turned off.

Here, because of natural gas or liquefied petroleum gas, in the case of the range hood is out of use, as long as the nitrogen compound is burned for a few minutes, the nitrogen compound will exceed the standard by 5 times, and the carbon monoxide gas can exceed the standard by more than 65 times.

As for the reason why it is still necessary to work for a few minutes after cooking, it is to discharge the residual harmful gases in the kitchen to the greatest extent and prevent them from remaining in the kitchen, so as to prevent harm to human health. This is the case for all users of piped gas buildings: the oil that adheres to the gas pipes is thick and difficult to remove.

Now introduce a preventive method: first carry out a thorough removal of the oil stain drilled into the gas pipe, and then use the paper strip (5 cm) cut into the waste wall calendar about 5 cm wide, and wrap it along the gas pipe, which is not only beautiful and generous, but also very convenient to exchange for dirty paper strips. Kitchen range hood degreasing method:

After the range hood is used, the oil basin should be cleaned, and the plastic bag used to wrap sweet oranges can be put into the oil box and close to the wall of the box. When the box is full of oil, remove the bag full of oil and replace it with a new bag. This not only solves the problem of unclean oil, but also uses waste plastic bags, saving time.

1. Match the kitchen stove and air volume. The number of kitchen stoves is strictly matched with the air volume of the equipment, so as to give full play to the best purification effect and make the fume treatment efficiency meet the emission standard. If the stove is added to the kitchen, it needs to be replaced and rematched to increase the air volume, and the fan power also needs to be increased in response to ensure the stable efficiency of the fume purifier.

2. Clean the electric field of the equipment in time. The purification efficiency of the oil fume purifier is greatly reduced, and it is known that part of the reason is that the internal electric field has not been cleaned for a long time, resulting in excessive accumulation of oil fumes in the internal electric field, which is attached to the electric field electric plate, and ultimately leads to poor ionization effect of the electric field, and the purification effect will become worse. Therefore, timely cleaning of equipment is an important step to maintain its purification efficiency.

3. Regularly inspect and maintain equipment. The whole set of fume purification system is composed of fans, purifiers, pipes and other components, so the coordination of each component is an important guarantee to maintain the purification efficiency.

The oil fume purifier is mainly used for the purification and treatment of low-altitude emission oil fume in the kitchen.

The oil fume purifier is mainly used for the purification and treatment of low-altitude emission fumes in the kitchen; It is used in hotels, restaurants, restaurants, restaurants, schools, institutions, factories and other places; food frying, cooking and processing industries; Oil splash heat treatment workshop, oil mist lubrication workshop, workpiece welding workshop and olefin oil boiler discharge and other industrial occasions.

Examples of small restaurants that were required to install fume purifiers:

The law enforcement officers of the Ansha Squadron of the Changsha County Administrative Law Enforcement Bureau came to Aunt Wang's family kitchen in Maotang Community, Ansha Town, again to inspect the installation and rectification of its fume purification equipment.

Previously, Aunt Wang's family kitchen was complained by residents for not installing fume purification equipment, and the law enforcement officers of the Ansha Squadron filed a case for investigation in accordance with the law, and finally made an administrative penalty decision of a fine of 5,000 yuan.

Aunt Wang's family kitchen fine has been paid and implemented in place, and a fume purifier has been installed, and the secondary test results have not exceeded the oil fume emission standard.

Law enforcement officials said that the punishment of the restaurant involved in the case is not the goal, the key is to make it understand the harm of oil smoke pollution and the importance of environmental protection, and urge it to rectify. Although some catering enterprises have been operating for many years, the fume purification equipment installed in the past cannot meet the emission standards due to the lack of regular cleaning and maintenance, and must be rectified in time.

People's Daily Online-A family restaurant in Changsha was fined 5,000 yuan for not installing a fume purifier.

Oil fume purifier refers to the treatment device of oil fume exhaust gas. The oil fume purifier is mainly used for the purification and treatment of low-altitude emission fumes in the kitchen; It is used in hotels, restaurants, restaurants, restaurants, schools, institutions, factories and other places; food frying, cooking and processing industries; Oil splash heat treatment workshop, oil mist lubrication workshop, workpiece welding workshop and olefin oil boiler discharge and other industrial occasions.

For oil fume purification, the oil fume purification treatment technology methods on the market include mechanical separation method, catalyst combustion method, activated carbon adsorption method, fabric filtration method, wet treatment method and electrostatic treatment method.

Regarding the handling of "Jiangxi netizens complaining about restaurant fume pollution":

In this regard, the Nanchang County Party Committee Office replied that after the investigation of the Nanchang County Environmental Protection Bureau, there are 7 restaurants under the 8 buildings of the Vienna Square Community, of which 5 are boiled restaurants, which basically do not produce oil smoke, and the other 2 are Wangke Huang Braised Chicken Rice Restaurant and Chen's Fast Food Restaurant, and the oil smoke is directly discharged into the sewer without treatment, resulting in a certain amount of oil smoke pollution.

The county environmental protection bureau has ordered two restaurants to install fume purifiers to meet the emission standards.

Answer 1: The biggest function of the fume purifier is, of course, to purify the fume. When the oil fume enters the electrostatic oil fume purifier, some of the larger oil droplets and oil particles are trapped on the flow sharing plate due to mechanical collision and retention. When the air flow enters the high-voltage electrostatic field, under the action of the high-voltage electric field, the oil smoke is degraded and carbonized, and the tiny oil particles are absorbed and discharged by the electric field.

At the same time, under the action of the high-voltage generator, the air in the electric field produces ozone, which can remove most of the odors in the flue gas and meet the national environmental protection requirements.

2. Keep the dishes fresh and delicious. In kitchens with large cooking smoke, oil fumes tend to adhere to the dishes, giving the dishes a complete cross-flavor. After installing the fume purifier, the kitchen environment becomes better and the dishes can remain fresh and delicious!

3. Protect the health of catering employees and nearby residents. Residents and chefs who come into contact with the restaurant industry can protect their health by installing fume purifiers.

Hello dear, I can't hear clearly, can I type.

Question: Is there any smoke when the fume purifier exhausts the fume?

Question: What is the use of a purifier?

Is it to purify the fumes?

Yes, pro question.

Why is it that the purifier I bought still has a lot of smoke going out?

Now engaged in the catering industry operators must install kitchen fume purifiers when opening stores, which is a mandatory regulation of the environmental protection department, if you refuse to install or install the fume purifier purification rate is not qualified, catering practitioners may be revoked business licenses. Therefore, choosing a good oil fume purifier is not only to cope with the EIA inspection, but also to be responsible for others and the environment!

If the catering unit does not have a fume purifier installed, the kitchen fumes will be emitted around the neighborhood during cooking. We all know that the smell of oil fume is very pungent, and long-term inhalation will also cause health problems

In a kitchen with a lot of fumes, it is easy for fumes to adhere to the cooked dishes, which will cause the cooked dishes to completely carry over the flavor. After installing a fume purifier, the kitchen environment will be better and the dishes will remain fresh and delicious

The people who come into contact with the restaurant industry are none other than nearby residents and chefs, and the installation of oil fume purifiers can protect their health.

Product Introduction:

Electrostatic fume purifier is mainly used for kitchen oil in hotels, restaurants, restaurants, restaurants, schools, institutions, factories and other places.

Smoke purification and control; food frying, cooking and processing industries; Oil splash heat treatment workshop, oil mist lubrication workshop, workpiece welding workshop.

and olefin oil boiler emissions and other industrial occasions.

Working principle (fume treatment technology):

The oil fume is sucked into the electrostatic oil fume purifier by the fan, and some of the larger oil mist droplets and oil particles are blocked on the flow equalizer due to mechanical collision and resistance.

Stay and ** set. When the air flow enters the high-voltage electrostatic field, under the action of the high-voltage electric field, the oil smoke gas is ionized, and the oil mist is charged, and most of it can be.

degradation and carbonization; A small number of tiny oil particles are collected on the plates under the action of the electric field force of the adsorption electric field and the action of air flow.

Under the action of its own gravity, it flows to the oil collection pan and is discharged through the oil discharge channel, and the remaining micron-level oil mist is degraded into carbon dioxide and water by the electric field, and finally discharges clean air; At the same time, under the action of the high-voltage generator, the air in the electric field produces ozone, which removes most of the odor in the flue gas.

Meet the national environmental protection requirements.

It adopts the dual role of mechanical separation and electrostatic purification. The fume-containing exhaust gas is sucked into the pipeline under the action of the fan, and enters the first-stage purification and separation equalization device of the fume purifier, and the gravity inertia purification technology is used to physically separate and balance the oil mist particles with large particle size. The separated large oil droplets flow into the oil and discharge under the action of their own gravity.

The remaining tiny particle size oil mist particles enter the high-voltage electrostatic field, the high-voltage electrostatic field adopts the electrostatic working principle of two-stage high and low voltage separation, and the electric field of the first stage ionization plate charges the tiny particle size oil mist particles and becomes charged particles, which are adsorbed and partially carbonized immediately after reaching the second-stage adsorption plate. At the same time, the ozone excited by the high-voltage electrostatic field effectively degrades harmful components, plays the role of disinfection, deodorization, and finally discharges clean air through the filter grid.
