Purification of soot

Chinese food has always been famous for its delicious food. However, due to the large proportion of fried, fried, cooked, and fried Chinese foods, a lot of fumes are produced. The components of the kitchen fume are complex, the amount of fume pollution is large, the surface is wide, and the low-altitude diffusion is strong. The person's intuitive reflection is strong. Oily smoke attachments have a great impact on environmental health and damage the image of modern and civilized cities. They are the enemies of health and environmental protection. Smoke fumes emitted by the catering industry seriously affect the air quality of cities.

For a long time, fumes from restaurants and residential areas in China have been fugitive emissions. The fumes contain a variety of harmful substances and are discharged outside without any treatment. This not only causes pollution to the surrounding residents' living environment, but also emits a large amount of hydrocarbons contained in soot to the atmosphere, which easily mixes with other dusts. The formation of inhalable particles destroys the air quality. At present, scientific experiments have proved that these compounds are harmful to human health, such as: inhalation of high-concentration oil fumes can cause lung diseases and tissue cell damage, decreased lung capacity; smoke fumes influence the body's cellular immunity, macrophage function , causing a decline in human immune function

There are two main sources of pollution in kitchen fumes; one is the use of harmful gases such as carbon monoxide, carbon dioxide, sulfur dioxide, and nitrogen oxides emitted from coal, gas, and liquefied gas fires; and the second is cooking fumes from cooking dishes. Although the hoods we often use today can eliminate most of the fumes in the kitchen, it is not able to completely solve the pollution of the entire environment caused by cooking fumes.

Composite fume purification equipment advantages Description: The structure is compact and reasonable, does not affect the appearance of the environment, does not form a secondary pollution, that is no noise pollution. The equipment is simple, investment is saved, and operating costs are low. The device integrates many advantages of liquid absorption technology and low temperature plasma catalysis technology. The treatment effect is good. The kitchen fume passes through the liquid absorption unit, water mist filter, plasma unit, catalytic unit, etc. After treatment in oil mist, carbon black Such particulate matter and gaseous pollutants can be well removed, and the technology is advanced and reliable.

The core of the technology is the low-temperature plasma unit. The key technologies are: (1) High-power, high-voltage, fast-rising-edge narrow-pulse power supply is designed and manufactured. This system has the characteristics of fast rising speed, arc protection, and overload protection. (2) High-voltage power supply and discharge, matching technology of the collector plate, insulation technology, and safety protection technology to ensure that the power supply works in an ideal load state. (3) Catalyst synthesis, loading and production techniques of catalyst plates, nano-materials in-situ assembly technology, auxiliary sintering, and surface activation treatment technologies to make the catalyst plate resistant to bombardment, corrosion, long life, and washable technologies condition. (4) The catalyst loading technology for purifying the filter, using an appropriate coating technique, the ozone purifying catalyst is loaded on the honeycomb cell material to make a filter. (5) Modular mechanism design, easy to clean and maintain, can meet the processing requirements for different polluting gases through multi-level combination.

In this process, most of the large-particle oil mist droplets are adsorbed and filtered due to inertial collision with the pretreatment section, so that the concentration of oil mist particles after flowing out of the pretreatment section is greatly reduced, and the low-density oil mist is small. The oil droplets, oil and gas, and organic matter are ionized, decomposed, and charred when passing through a multi-level high-voltage electrostatic field of a certain intensity. The equipment for oil fume purification has a very high removal rate of oil mist, and the smoke can be treated by a water film staticizer. Discharge.
