Abstract

The invention provides a gas boiler flue gas moisture removal treatment system for municipal sludge drying incineration treatment. An automatic smoke temperature adjusting device with a PID adjustingfunction is additionally arranged, the PID-adjusted automatic smoke temperature adjusting device comprises a TIC temperature measurement display thermocouple and an intelligent control module, the TICtemperature measurement display thermocouple is arranged at the outlet of a chimney, after the TIC temperature measurement display thermocouple inputs a measured flue gas temperature into the intelligent control module, the intelligent control module controls a steam system to adjust the opening degree of a pneumatic control valve, and steam enters a flue gas-steam heat exchanger through a pipeline, exchanges heat with flue gas and then is discharged through a drainage system; and the temperature of the flue gas is further increased to achieve moisture removal after the flue gas exchanges heat with steam through a flue gas-steam heat exchanger at the inlet of the chimney, and then the flue gas is exhausted from the outlet of a chimney. The system can be automatically adjusted in the wholeprocess, manual intervention is not needed, and the problem of moisture plume existing in existing sludge drying incineration treatment can be effectively solved.

Description

technical field [0001] The invention relates to a gas boiler flue gas dewhitening treatment system, in particular to a gas boiler flue gas dewhitening treatment system for municipal sludge drying and incineration treatment. Background technique [0002] In the municipal sludge drying and incineration treatment, it is necessary to use gas-fired boilers to provide auxiliary steam sources for sludge drying and incineration. The gas-fired boiler uses natural gas for combustion, and the product is H 2 O and CO 2 , the moisture in the flue gas exists in the flue gas in a gaseous state. In order to improve the thermal efficiency of the gas-fired boiler, the boiler flue is equipped with an economizer and an air preheater, and the exhaust gas temperature can be reduced by 60-70°C. During the operation, it was detected that the humidity of the flue gas at the outlet of the air preheater was high, and the flue gas contained water mist or tiny water droplets. When the flue gas is di...
