What are the exhaust pipe design requirements for catering fume purifiers for the catering industry

1. If it is installed on the side of the balcony, it must be paid attention to whether the smoke exhaust pipe passes through the lintel of the building. In principle, the property management department is not allowed to punch too many holes in the smoke exhaust pipe.

Second, if the fume purifier is installed outdoors, it will be better solved. We only need to design the smoke exhaust pipe 800 degrees above the ground. To ensure the safety of employees, extend the pipes to the outside of the kitchen, such as the top floor.

3. If it is installed indoors, when the smoke exhaust pipe is designed again, you need to know the height and total area of the room, which shape is suitable for designing the smoke exhaust pipe, and the purification equipment needs to be installed in the upper part of the kitchen. When the smoke exhaust pipe of the oil fume purifier enters the flue through the hanging cabinet body, it should be noted that the smoke inlet should be set up in the height and depth of the hanging cabinet body, and the edge of the lower smoke inlet above a specific size is best between 2000-2200, and the distance between the outer edge of the smoke inlet and the back wall should not be greater than 250, so as to ensure that when the hanging cabinet is installed, the smoke exhaust pipe can have enough space to lead the smoke exhaust pipe to the front of the gas meter and gas pipeline.

Smoke machines are not suitable for this method because the upper part of the smoke machine usually has a cabinet and the smoke exhaust pipe has space for guidance. The reason for this is that the upper part of the smoke machine usually does not have a cabinet. If this method is required, the wall cabinets on both sides need to be heightened to allow a space in the upper part of the smoke machine and the top of the wall cabinet to guide the pipes.

The upper part of the European smoke machine is designed to be closed to avoid the smoke exhaust pipe from sagging and bypassing, affecting the smoke exhaust effect and visual aesthetics. Regardless of the method, the smoke extraction pipe must be designed to be natural and smooth to achieve good smoke extraction.

The standard state at a temperature of 273K and a pressure of 101325Pa.

The State Environmental Protection Administration has stipulated the "Emission Standards for Cooking Fumes" as follows:

Emission standards for cooking fumes;

1. Scope. It stipulates the maximum allowable emission concentration of oil fumes, odor concentration, minimum removal efficiency of oil fume purification facilities, and minimum emission height of oil fume exhaust cylinders in catering enterprises. This standard is applicable to the management of fume emissions from existing catering units in urban built-up areas, nature reserves and scenic spots, as well as the design, environmental impact assessment, environmental protection acceptance and management of fume emissions during the operation of new, expanded and reconstructed catering units; The internal staff canteens of food processing units and non-operating units that emit oil fumes shall be implemented with reference to this standard.

This standard does not apply to residential household fume emissions.

2. Standard status. The state at a temperature of 273K and a pressure of 101325Pa. The concentration standard value and exhaust air volume specified in this standard are the dry flue gas values under the standard state.

3. Cooking fumes. Mixtures of volatile oils, organic matter, and thermal oxidation or pyrolysis during food cooking and food production and processing.

4. Fume purification equipment. Equipment for purifying oil fumes generated in food cooking and food production and processing.

5. All smoke exhaust stoves belonging to the same legal person in the same building shall be counted as one catering business unit.

Hello! Catering fume purifier exhaust cylinders are not allowed to be discharged from residential areas. In order to protect people's lives and health and environmental protection, relevant laws, regulations and standards clearly stipulate the exhaust emission standards of catering fume purifiers, and require that the emitted fumes shall not affect the living environment of surrounding residents.

At the same time, in order to further investigate the destruction of Yuzhen and reduce the impact of catering fumes on the environment, some areas also stipulate that restaurants must install fume purifiers, and require that the crude fumes emitted by the purifiers must be treated and can only be discharged after reaching national standards. If the catering fume purifier directly emits pollutants, it will have a serious impact on the lives of the surrounding residents, and it should be rectified and treated.

Hello, I have helped you find the results of the pin: the exhaust cylinder of the catering fume purifier is allowed to be discharged in residential areas, but it needs to comply with the national or local technical standards. These standards will clarify the "Maximum Emission Limits and Control Technical Requirements for Catering Fume Exhaust Cylinders", under the provisions of the technical standards, the exhaust cylinders of oil fume purifiers can be discharged in residential areas.

The emission standard of the exhaust system for oil fume points out that through the chimney of the oil fume purifier, the emission of oil loss and high smoke should be controlled according to the maximum emission rate of 5 mg NM3. In addition, the emission requirements for the exhaust cylinder of the catering fume purifier in residential areas are also different.

For example, in areas with high requirements for the concentration of oil fume pollutants, it may be necessary to require the installation of more advanced oil fume purifiers to ensure that the emission of food and beverage fumes meets the standards. At the same time, fire safety inspections can also be carried out in residential areas to ensure that the installed fume purifiers can work properly.

Catering fume pollution prevention and control facilities should include fume exhaust gas purification devices, special fume emission channels and what hello pro-stove congregation, 1It is necessary to install a supporting oil fume purification device and a special smoke exhaust channel to achieve centralized emission of oil and smoke and solve the odor pollution of oil smoke. 2. For fans, air conditioning and refrigeration equipment and other equipment that are prone to noise, sound insulation panels, vibration damping pads and other sound insulation and vibration reduction facilities should be built to ensure the normal operation of noise pollution prevention and control facilities and ensure that the noise meets the emission standards stipulated by the state.

3.Loudspeakers and other noise-generating audio equipment used in business operations must be removed. 4.

There is a complete sewage discharge system, and the discharge of catering wastewater into the urban sewer network should meet the relevant requirements of the city management department, and the construction of sewage oil separation facilities, regular cleaning to ensure the normal operation of the grease trap. 5.It should comply with the relevant provisions of the "Food Hygiene Management Measures for the Catering Industry", and kitchen waste must be collected, stored and disposed of in accordance with the relevant provisions of the city management department.

Is the catering industry covered by the pollutant discharge permit? Is there a location requirement for the installation of the oil fume purifier?

Two stoves, the Environmental Protection Bureau generally only requires the environmental impact registration form, not stupid need to find a qualified environmental protection code orange division to do environmental impact assessment, go to the Environmental Protection Bureau to fill out a registration form! After getting the approval, we will do environmental protection in accordance with the requirements! In the catering industry, sewage, oil smoke and noise are all required to be discharged!

Sewage is generally separated from oil and slag, and can be directly discharged into the municipal pipe network; Oil smoke requires high-altitude emission (now basically low-altitude emission is not allowed), and the emission concentration after oil smoke treatment is required to be less than 2mg m! In fact, the fume purification equipment at home and abroad basically cannot meet this requirement, but since there are regulations, it still has to be done. Two burners, the exhaust air volume is about 5000 6000m h, according to this selection of fume purifier, (generally the smallest model)!

The noise is generally the noise of the exhaust group fume fan, and making a muffler can basically solve the problem!
