What installation matters should be paid attention to in catering fume purifiers?

1. Select the matching fan air volume, the air volume of the fan is generally not greater than the treatment air volume of the purifier can not be greater than 5%, (this data is for reference only, the specific situation is determined by the engineering contractor, if the air volume of the fan is too large than the maximum treatment air volume of the purifier, it will affect the purification effect of the purifier);

2. The corresponding treatment air volume of each stove and each meter of smoke hood is about 2000m3 h, and the total treatment air volume is determined according to the number of stoves, the length of the smoke hood and the installation position and the specifications and models of the corresponding purifier are selected;

3. Install the distance between the purifier and the outlet of the hood at least 3 meters to ensure fire safety and purification effect; The distance between the purifier and the fan is more than 2 meters;

4. Before the installation of the machine, Zizhu Environmental Protection suggests that it is best to power on for a trial period to check whether the electrodes of the machine will be offset during transportation or handling;

5. The air inlet and outlet of the machine can be interchangeable at will, and there must be a filter in the direction of the air inlet;

6. After connecting the oil drain pipe, start the purifier;

7. Before starting the purifier, you must start the fan for 10 minutes, especially in the cold winter, the time for the fan to start first should be a little more, and the purifier should be turned off before stopping the fan.

Choose the corresponding purifier according to your oil smoke level, it is recommended to choose some ones with low noise and do not disturb the people; Otherwise, the follow-up comprehensive law enforcement will not be passed.

According to the requirements of catering fume control in the jurisdiction, it is necessary to install a fume purifier. Muslim Street is a small place with a small shop space.

How do you install this purifier? Indoor or outdoor? Which way is less damaging to the machine? The equipment is installed in a high ridge resistance.

Common oil fume purifier installation is divided into indoor installation and outdoor installation.

Dry goods: installation methods and precautions for oil fume purification equipment!

The location where the device is installed.

First of all, determine whether there is enough space reserved for the installation of the oil fume purifier.

The second position is installed on the smoke exhaust pipe connected to the hood and pipe. Generally, most people will choose outdoor installation, which can save space in the catering kitchen.

If the outside space is limited, it is feasible to install it indoors. Principles of equipment installation.

The installation of fume purification equipment follows the principle of adapting measures to local conditions and flexible use.

Best purifying effect.

The equipment is installed at a distance of 3-8 meters from the smoke hood, which is placed in the best position for the fume purification to ensure fire safety and purification effect.

Due to China's emphasis on fume pollution in the catering industry, many places across the country require catering units to install fume purifiers. The oil fume purifier is already a must-have environmentally friendly product in the catering kitchen.

However, there are still some catering units that do not have a high awareness of the environment, many restaurants in order to save costs to install ordinary fume purifiers, and even some restaurants do not install fume purifiers, thinking that fume purifiers are a burden, that fume purifiers can not bring direct profit benefits to restaurants, and can not be installed without installing attitude. As a result, the problem of oil smoke pollution is becoming more and more serious.

According to the "Emission Standards for Cooking Fume" stipulated by the State Environmental Protection Bureau, restaurants are most required to install qualified fume purifiers, otherwise they will be fined or rectified, or even shut down their stores. What are the negative impacts on food and beverage outlets?

1.The relevant national policies stipulate that once the restaurant does not install the fume purifier, once it emits a pungent smell and causes complaints or even complaints from the surrounding residents. The environmental protection department will fine him.

Even if the catering establishment is not fined, it will be required to suspend business for rectification. The money that was fined was even more than the money for the fume purifier.

2.harm to human health; In order to save money, some small restaurants have purchased inferior oil fume purifiers in order to save money or cope with the environmental protection bureau, but they have not achieved the desired effect after installation. As a result, the quality of the environment in the kitchen is poor, which directly affects the physical and mental health of chefs and employees who cook all the time.

3.Pollution to the surrounding environment; Catering establishments that do not have fume purifiers installed will pollute the surrounding air environment and will also pollute the wall surfaces of buildings. It will also affect the bad impression of customers and surrounding residents on the catering unit, and have a negative impact on catering consumption.

Catering practitioners must pay attention to this problem and legally standardize the installation and use of oil fume purifiers. The installation of oil fume purifiers that meet the national emission standards can pass environmental protection inspections, and can also provide a good working environment for staff, but also to avoid oil fumes in time to cause harm to people and the environment.

Here, we remind everyone to actively install the fume purification device to avoid adverse consequences caused by not installing or failing to install the standard.

To install a fume purifier, you must install a high-efficiency fume purifier, like the Kuaiba fume purifier **Although it is a little expensive, it has a good effect, a long service life, timely and thoughtful after-sales service, and the most important thing is that the fume emission standards fully meet the environmental protection requirements.

1. First of all, select the installation location, suitable for the specifications and models of the fume purifier, the stove and the fume purifier are about 4000m3 h, and the effect is better.

2. The air volume of the selected fan should match the stove, and the air volume should not be greater than 5% of the disposal air volume of the purifier. The details are determined by the contractor according to the site conditions, if the air volume of the fan is greater than the air volume of the purifier disposal will also affect the effect of oil fume purification.

3. The distance between the installed purifier and the outlet of the fume hood is more than 3 meters, so that the fire safety can be ensured and the fume purification effect can be improved; The distance between the oil fume purifier and the fan is generally more than 2 meters, which is more appropriate.

4. The installed fume purifier is first energized and tried to run, and then the electrodes of the machine are checked to see if there is any deviation during transportation and operation.

5. The air inlet and outlet of the fume can be easily interchanged, preferably left in and right out, and the direction of the air inlet must be equipped with a filter.

6. The discharge must be connected to the oil discharge pipe at high altitude.

7. When you are ready to turn on the fume purifier, you must first turn on the fan and let the fan run for more than 10 minutes. The lower the temperature, the longer it will take to start the fan, and it is the opposite to turn off the fume purifier and then the fan.

8. All air ducts must be connected to take anti-leakage measures. In order to ensure the infection efficiency of the equipment, the reducer air duct adjacent to the air inlet and outlet of the equipment should be kept as smooth as possible. Smooth pipes are used to connect, and soft connections must be used when connecting the air ducts of fans.

1.The grinding cover of the catering fume purifier and the fan equipment box must be safely grounded, the air inlet and outlet of the machine can be exchanged at will, and the air inlet must have a filter screen.

2.This equipment can be installed indoors and outdoors, and the purifier should be installed outdoors to prevent rain from disassembling above the machinery to prolong the operating life of the machinery.

3.The equipment needs to reserve maintenance space around it, and the chassis door should have a free opening space of more than 90 degrees at a right angle for future maintenance, washing, and maintenance.

4.It is best to power on this equipment for a period of time before installation to test whether the electrodes of the machinery will be offset during transportation or handling.

5.Connect the oil drain pipe to ensure safety, this equipment can be linked with the fan, which means that the equipment and the fan are turned on and off at the same time; If it cannot be linked, the fan must be started before starting the socks letter of this equipment, and the fan must be started for 10 minutes (especially in the cold winter in the north, the time when the fan starts first should be longer), and the purifier should be turned off before stopping the fan when shutting down.

6.This equipment is connected to the exhaust duct through the falange, and all adjacent connections should be sealed to prevent oil leakage. 7.Install a minimum distance of 4 meters between the catering fume purifier and the outlet position of the fume hood to ensure fire safety and purification effect;

In order to ensure the purification effect, the exhaust air volume is required to be calculated in strict accordance with the suction air velocity of the exhaust hood during the actual design, and the suction speed of the hood is usually not less than, and the minimum exhaust air volume is usually calculated by the following formula: L = 1000PH formula: L - exhaust air volume of the exhaust hood, m3 h; p-perimeter length of the hood (the edge against the wall is not counted), m; h-The distance from the hood to the cooktop, m; After calculating the exhaust air volume with the above formula, the suction speed of the hood mouth is calculated according to the area of the hood.

Ensure that the suction speed of the hood is not less than, in the actual engineering design, the method of estimation is often adopted, according to the provisions of the "Technical Measures for HVAC Design of Civil Buildings" on the ventilation volume of the kitchen, the ventilation volume of the kitchen can also be told to the cruise ship according to the following number of ventilation times to determine: Chinese kitchen; l=40 50 (times h); Western kitchen: l=30 40 (times h); staff canteen; l=25 35 (times h).

To improve indoor air quality, we must install a catering fume purifier in the restaurant downstairs, which can purify the fume exhaust gas, remove the odor, and prevent the infection of germs.

The installation of oil fume purifiers needs to maintain industry standards, and the installation avoids the above misunderstandings.
