Spraying system and exhaust gas treatment device

Abstract

The utility model discloses a spray system and exhaust treatment device, including jar body, circulating pool, circulating pump and spray set, the liquid inlet end of circulating pump is connected with circulating pool through pipeline, the liquid outlet of circulating pump is connected spray set through header, still include dosing pump, the liquid inlet end of dosing pump is connected with jar body, the liquid outlet of dosing pump is connected with header through dosing pipe, still be connected with detection tube on the header, be provided with pH detector on the detection tube. Compared with prior art, the new dosing of the utility model is diluted through header, and then is reacted through spray set and exhaust gas, and then is collected by circulating pool, at this moment, the neutralization liquid pH in washing tower pool is monitored by pH detector, so it will not be influenced by dosing transiently, and the single dosing amount of dosing pump can also be optimized, so that the neutralization liquid keeps stable pH, reduces the start-stop frequency of dosing pump, and reduces the risk of leakage at pump related interface.
