Smoke and smoke smoke hazards and treatment methods!

Date:2017-6-26 16:07
Fumes are all kinds of manufacturers of kitchen cooking oil fumes generated when the gas molecules. Fire smoke is completely or incomplete combustion of the stove when the emissions of harmful gases, is free of carbon-based black smoke, flocculent, easy to adhere to the solid material, the rest is COX, SO2, NOX, is a high concentration of dust
Fumes, smoke hazards:

Fumes contain many substances that are seriously hazardous to the human body and increase the chances of people suffering from lung cancer. Kitchen smoke is also one of the major air pollution, gas is acidic, easy to form acid, will pollute the water and soil and corrosion buildings.

Governance:

Filtration adsorption oil flue gas purification equipment can be used with high oil absorption properties of organic polymer composite fabric or felt, inorganic filter materials (hydrophobic perlite, ceramsite, coke, etc. used alone or in combination), the filter material can be with the smoke Gas flow direction vertical or parallel to the direction of placement, purification efficiency of more than 80%.

Electrostatic fume purification:

Electrostatic deposition method is the introduction of oil mist into the high-voltage electric field, so that fumes, smoke in the smoke charge, in the electric field force to the dust pole movement and deposition down. Purification efficiency is usually up to 85% or more, the pressure drop is small.

Low temperature plasma method:

The principle is the use of high-voltage electrostatic method at the same time, in the electrostatic field at the front of the plasma field, the use of its high energy excited by a large number of free radicals on the soot particles degradation, so that the viscosity decreased; in the plasma generation process, The resulting instantaneous high energy, can open some of the harmful gases of the chemical bond, so that it is broken down into elemental atoms or harmless molecules. The technology is currently on the market the most advanced fume, smoke treatment technology, high removal rate (90%), after treatment, no smell odor, easy maintenance, but the equipment investment is high.

The high concentration of the kitchen smoke gas using swirl plate water spray method, the use of cyclone plate spray tower, the gas in the tower from the bottom up high-speed movement, and from the top down the washing liquid contact, due to The tower is equipped with a multi-layer swirl plate, which can increase the gas-liquid contact area and contact time, so that the tail gas and water in the tower and the board full contact. Pollutants in the exhaust gas Carbon black in contact with the spray water, the water is fully adsorbed, to be purified; exhaust NOx, SO2 and other gaseous pollutants by adding a certain percentage of water in the spray water to spray water was alkaline , In the process of spraying, water and tail gas contact, a chemical reaction, so that NOx, SO2 and other gaseous pollutants get neutral and achieve a good treatment effect.
