Particulate trap is a filter installed in the emission system of diesel engine, which can catch particulate emissions before they enter the atmosphere.

The most commonly heard pollutants in daily exhaust are particulate matter (PM), nitric oxide (CO), hydrocarbon HC, nitrogen oxide NOx. However, particulate matter is the general term of various solid particles in exhaust gas, which usually includes heavy metal compounds, sulfates, soot particles of soluble organic matter, and liquid particles coated with fuel oil, etc; Carbon monoxide is a kind of gas produced by the combustion of fuel under the condition of insufficient oxygen; Hydrocarbon is a general term for compounds formed by carbon and hydrogen. It refers to the carbon and hydrogen compounds, fuel vapor, etc. generated by the unburned fuel or lubricating oil in the cylinder or by decomposition. Nitrogen oxide is a gas formed by the oxidation of nitrogen in the cylinder at high temperature, which is mainly composed of nitric oxide and nitrogen dioxide.

The DPF treatment standard is ringerman blackness level 1 and below, which is applicable to domestic and imported brands, and the applicable power is 50kw-2500kw. The DPF diesel exhaust particulate trap is a carbon particulate trap that removes C particles by physical filtration and is regenerated by water washing. When the carbon is saturated, loosen the clamp, extract the unit filter element, and wash it with tap water for 30-40 seconds to complete the regeneration of a unit. The particle trap box is made of stainless steel, with long service life and 10-15 DB noise reduction function. The black smoke treatment efficiency is 90% - 98%. It is also equipped with a safety bypass, which can be automatically opened when the blockage causes a high back pressure alarm to ensure safe use.

With the rapid development of modern industry, all enterprises and departments are faced with the unshirkable responsibility of eliminating pollution and protecting the environment. While fulfilling this responsibility, it is a very important technical work to choose economical and practical purification equipment to deal with NOx, S02 and dust in the discharged furnace flue gas.
