Finely ground particle substance is filtered.
As further optimization, S2) in reducing temperature twice include primary temperature reducing and secondary cooling, primary temperature reducing is useless to high temperature
Gas is cooled down by the heat exchange of high temperature air water；Secondary cooling carries out again the exhaust gas after primary temperature reducing by the heat exchange of low temperature air water
Cooling.
As further optimization, the high-temperature water generated to primary temperature reducing is recycled；The cleaning that secondary cooling is generated
Hot water carries out Treated sewage reusing.
As further optimization, S7) in except the processing of white vapour includes level-one high temperature except white vapour and second steam remove white vapour.
As further optimization, level-one high temperature is heated except white vapour using the high-temperature water that primary temperature reducing generates；Second level
Steam is heated except white vapour using enterprise's overbottom pressure steam.
As further optimization, level-one high temperature removes the water at low temperature conveying generated after white vapour for primary temperature reducing.
As further optimization, S3) in exhaust gas and mixed flowing liquid carry out gas-liquid emulsion reaction, pass through what rotation generated
Centrifugal force carries out gas-liquid separation, adsorbs pernicious gas by shower spray of solvent, by removing water drop except water layer, demisting, removing solvent.
As further optimization, exhaust gas is tangentially mixed with mixed flowing liquid.
As further optimization, intake air temperature and exhaust ports discharge at air inlet are monitored by monitoring device
The smell of gas.
Compared with prior art, the invention has the benefit that
1. by secondary filter, reducing temperature twice, the removal of impurities of mixed stream, Electrostatic Absorption, water removal demisting, deodorization and removing white vapour multiple tracks
Process carries out purified treatment to printing and dyeing exhaust gas, can be more to large particulate matter, finely ground particle substance, wax and oil smoke in exhaust gas etc.
Kind dopant is removed one by one, purifies wide coverage, and clean-up effect is excellent, accomplishes that colorless and odorless discharges；
2. recycling water resource and thermal resource by measures such as Treated sewage reusing, recyclings, energy-saving and emission-reduction reduce enterprise
Resources costs.
Detailed description of the invention
Fig. 1 is process route chart of the invention.
Specific embodiment
The following is specific embodiments of the present invention, and technical scheme of the present invention will be further described, but the present invention is simultaneously
