Description

Washing filtering deduster

Technical field

The present invention relates to deduster more particularly to a kind of washing filtering dedusters.

Background technique

Environmental concerns are to everyone healthy and live, but with the rapid development of industry, the use of various boilers is got over Come more, the flue dust and toxic gas of generation seriously polluted atmosphere, so it is extremely urgent to eliminate flue dust, purification air. The maximum stomach flue dust of content, sulfur dioxide, followed by carbon monoxide, hydrocarbon, nitric oxide and photochemistry cigarette in flue gas Mist.These pollute most of various Industrial Boilers, station boiler and civil boiler from burning coal.The harm of flue gas have with Lower several points:

1, dust: the dust being discharged from boiler chimney, granularity is extremely slow less than 10 μm of sinking speed to the ground, especially Sky can be floated on throughout the year referred to as " floating dust " less than 0.1 μm.Contain various toxic metal particles in " floating dust ", such as After sucking lung by people, there will be half to be adhered on lung.When " floating dust " concentration reaches 100mg/ ㎡ in air, can cause various Respiratory disease, it is serious to will lead to asthma, pneumoconiosis merging lung cancer.When it floats house can be stain into workshop, workshop and electromechanics is set It is standby, influence its service life.

2, sulfur dioxide: sulfur content is generally 0.5%~4% in coal, and also some is up to 8%.In coal burning in coal Sulphur reacted with oxygen generate sulfur dioxide gas, when in air sulfur dioxide concentration be greater than 0.1ppm when, to post, equipment It would detract from hurting or corrode.Sulfur dioxide meets water vapor in air and generates sulfuric acid mist, is often combined together with " floating dust " and endangers animal And post.In addition the person of directly contributing of sulfur dioxide or acid rain.

3, carbon monoxide: is generated due to non-complete combustion of fuel.Its service life in an atmosphere is very long, generally can be with Keep 2-3.When content is more than 100ppm to carbon monoxide in an atmosphere, can make one to generate the even poisoning of dizziness, dizziness, nausea It is dead.

4, photochemical fog: being that the hydrocarbons such as nitric oxide and methane in flue gas shine through the ultraviolet light in sunlight It penetrates and generates acetaldehyde, ozone or other nitrous oxides and be formed by light blue smog.When photochemical fog content is more than When 0.3ppm, inflamed eyes, pest mass propagation, rubber product aging quickening, building damage of people etc. can be made.This direct shadow Ring the health and living environment for arriving people.
