Shenyang Shenyang ventilation pipeline Tell you Ventilation duct What should be done for anti-corrosion and thermal insulation?

1. Select kitchen fume purifier, and give priority to the type of fume purifier.

At present, there are mainly five kinds of smoke purifiers on the market: electrostatic oil smoke purifier, UV photolysis oil smoke purifier, composite low altitude emission purifier, wet (with water hood) oil smoke purifier, and water filtering oil smoke purifier. UV photodegradation machine has good purification effect, but the cost is relatively high, which is unacceptable to ordinary customers. Therefore, at present, the composite low altitude emission purifier is the mainstream of the market and the choice of most customers. This paper summarizes the comparative analysis of various purification methods for ventilation ducts, which can be selected according to the actual situation.

2. The type of oil smoke purifier is determined. The next step is to determine the air volume of the ventilation pipe of the oil smoke purifier, which is mainly determined according to the number of stoves. The air volume required for each stove is about 2500-3500.

It should also be considered according to the specific discharge environment of the ventilation pipeline, whether it is close to the nearby residential area, and what the restaurant mainly does. If you want to cook Sichuan food, Hunan food and other dishes with heavy taste, the air volume needs to be larger.

3. In addition to the air volume of the ventilation pipe, the size of the fume purifier should also be considered. In general, the larger the size of the electrostatic fume purifier, the larger the air volume to be treated.

Necessity of anti-corrosion and thermal insulation of ventilation pipeline: when the air pipe is conveying gas, the air pipe shall be derusted and coated with anti rust paint, and the dusty gas can be sprayed with anti loss protective layer. When high-temperature or low-temperature gas is transported in the air duct, the outer wall of the air duct shall be insulated. When the ambient air humidity is high, the outer wall of the air duct shall be subject to anti-corrosion and rust prevention treatment. The purpose of thermal insulation for pipes conveying high-temperature gas is to prevent the heat loss of the air in the pipes (this can happen in the air conditioning system in winter), prevent the heat from diffusing into the space when transporting waste hot steam or high-temperature gas, and prevent people from contacting the pipes and being scalded. In summer, condensation often occurs when transporting gas. Cold treatment is also required.
