Description
Technical field
The invention belongs to technical field of waste gas treatment, it is related to a kind of house exhaust processing unit, particularly a kind of leather car
Between emission-control equipment.
Background technology
Leather workshop carries out the processing such as dyeing to leather, can produce some waste gas, and these waste gas have stronger to human body
Excitant, if do not discharged outside workshop, can pollute the air ambient in workshop, and influence workman's is healthy.Therefore, logical
Normal way is to install draft fan on the wall in workshop, detaches the waste gas in workshop using draft fan and is discharged to air
In.Such waste gas discharge mode, is discharged by draft fan again because waste gas has been filled with workshop, and exhaust-gas treatment effect is not
Good, in addition, when there is strong wind open air, draft fan exhaust emissions effects are bad, or even strong wind pours in down a chimney into workshop from draft fan, sternly
Ghost image rings waste gas discharge, meanwhile, waste gas is directly discharged to also be unfavorable for environmental protection in air.
The content of the invention
The purpose of the present invention is directed to existing technology and there is above mentioned problem, it is proposed that a kind of leather house exhaust treatment dress
