Clean sealed boiler flue gas desulfurization and denitration device with filtering function

Abstract

The invention discloses a clean sealed boiler flue gas desulfurization and denitration device with a filtering function. The device comprises a boiler body, a placement strip, a cooling tower, a fixing ring, and a water pump, the upper end of the boiler body is seamlessly connected with a smoke-outlet pipe, the outer wall of the cooling tower is seamlessly connected to the input end of a smoke-inlet pipe, the output end of a driving motor is flanged to a rotating shaft, the fixing ring is fixedly welded to the inner bottom end of the cooling tower, and the output end of a condensing tube is injection-connected to a collecting pipe. The clean sealed boiler flue gas desulfurization and denitration device with filtering function has a connection manner of slot connection between the smoke-outlet pipe and the connecting pipe and between the connecting pipe and the smoke-inlet pipe, a user can conveniently perform disassembly and assembly between the smoke-outlet pipe and the connecting pipe and between the connecting pipe and the smoke-inlet pipe, the situation that the pipe connection is too long and the inside is prone to blockage is avoided, so that the user can timely dredge and clean the inside of the pipe, and a sealing gasket is beneficial to increase of the sealing performance between the pipes.

Description

technical field [0001] The invention relates to the related technical field of boiler flue gas treatment, in particular to a clean and sealed boiler flue gas desulfurization and denitrification device with filtering function. Background technique [0002] The dust contained in the boiler flue gas, including fly ash, carbon black, sulfur and nitrogen oxides, is a substance that pollutes the atmosphere. If it is not purified, its emission index can reach several times to dozens of times the environmental protection regulation index. Measures to discharge these substances include pre-combustion treatment, improved combustion technology, dust removal, desulfurization and denitrification, etc. The use of high chimneys can only reduce the concentration of pollutants in the atmosphere near the chimney. Therefore, in order to avoid the impact on the air in the natural environment, it is necessary to The flue gas in the boiler is desulfurized and denitrified, so the boiler flue gas d...
