Is the catering fume purifier equipment installed outdoors waterproof?

The fume purifier can be installed indoors or outdoors, but there should be enough space for maintenance and repair; The general catering fume purifier equipment has a waterproof function, but I am afraid that in case of an impact on the catering fume purifier equipment, it is better to prepare for waterproofing, and the catering fume purifier is mainly installed outdoors, so it is prepared for waterproofing. Moreover, the long-term wind and rain is more or less affected by the use and life of the catering fume purifier equipment, so whether the catering fume purifier is waterproof or not, it is better to prepare waterproof facilities for the installation of the catering fume purifier equipment.

Precautions for the use of oil fume purifier:

1. It needs frequent cleaning and maintenance. If it is not cleaned for a long time, it may cause the oil circuit to be blocked, and then the waste oil will accumulate, the motor load will increase, and the motor will burn out in serious cases. The flue is narrow or the smoke exhaust pipe is too long, resulting in large suction and small displacement, and the two are disproportionate, so that the residual air circulation in the wind silo is intensified, causing the whole machine to shake and make great noise.

2. Do not use a moist rag and sliding detergent to wipe the range hood switch when cleaning, as long as the oil circuit is unblocked, and it is best to need professionals to clean it.

3. If it is a large-scale fume purifier product, it must need professionals to clean, and the larger equipment is in hotels, restaurants, canteens and other places, and the purifier is not only conducive to smooth kitchen smoke exhaust, but also can eliminate fire hazards. The connections of each air duct shall take anti-leakage measures. To ensure the contagious efficacy of the device.

The variable diameter air duct adjacent to the air inlet and outlet of the equipment should be as smooth as possible to ensure the infectious effect of the equipment. Straight pipes that are more than 4 times longer than the diameter of the pipe must be assembled and connected with smooth pipes. Therefore, the soft connection must be used when the air duct connection of the equipment light fan is used.

If the device is vibrated while it is running, it will not be able to perform properly.

The type and operation mode of the oil fume purifier equipment can be selected according to the actual situation. Before the installation of the fume purifier, it is necessary to first calculate the actual operating parameters of each part of the fume exhaust system, including the operating resistance and exhaust air volume. If it is a new project, the impact on the exhaust system after the installation of the oil fume purifier should be fully considered in the design; When the catering fume purifier equipment is installed and designed, the waterproof problem is solved, so the catering fume purifier equipment is waterproof in the process of use, but the waterproof and rainproof facilities of the catering fume purifier are prepared in advance for the catering fume purifier equipment during installation.

If it is a renovation project, the exhaust system needs to be re-calculated when installing the fume purifier, and if necessary, the smoke hood, smoke exhaust pipe and the overall kitchen air supply device should be modified and the smoke exhaust fan should be replaced. The exhaust speed shall not be less than 10m s according to the specification, in order to prevent the oil from adhering to the flue due to the low wind speed, and the branch pipe connected to the exhaust hood shall be equipped with an air volume control valve. The unreasonable design and installation of smoke exhaust pipes often cause the kitchen smoke exhaust to be unobstructed, which directly affects the use of oil fume purifiers.

The horizontal section of the smoke exhaust pipe in the kitchen should not be too long, and the maximum distance of the general horizontal should not exceed 15m and have a slope of more than 2%, and the horizontal end should be set up with a union to facilitate the cleaning of grease. It is normal for catering fume purifier equipment to be waterproof, so it depends on whether you want to add waterproof measures or not.

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.

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.

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.

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.
