Abstract

The invention discloses a boiler flue gas afterheat recycling device. The boiler flue gas afterheat recycling device comprises a tank body; the middle part of the bottom end of the tank body is provided with a mounting hole; the inside of the mounting hole is in threaded connection with a sealing cover; one side of the top end of the tank body is fixedly connected with a filter tank; one side of the top end of the tank body is fixedly connected with a filter tank; the middle part of the top end of the tank body is fixedly connected with a draught fan; one side of the filter tank is fixedly connected with the draught fan through a connecting pipe; the left side of the bottom of the filter tank is movably hinged with a cover plate through a connecting lug; one side of the cover plate is fixedly connected with an air charging pipe; and the top of the cover plate is fixedly connected with a locking sleeve. The boiler flue gas afterheat recycling device can be used for heating cold water inside a heat accumulating tube so that the afterheat in flue gas can be recycled, and the resource utilization rate is increased; a servo motor is used for driving a screw to rotate so that a crossbeamis used for driving a cleaning brush to move horizontally, thus the dust on the surface of the heat accumulating tube can be cleared; and reduction of heat exchange efficiency caused by dust accumulation can be prevented.

Description

technical field [0001] The invention relates to a waste heat recovery device, in particular to a boiler flue gas waste heat recovery device. Background technique [0002] With the development of society, industrial production technology is also constantly improving. Industrial boilers are commonly used devices in industrial production processes. Industrial boilers can provide steam for power generation or gas supply. They are important thermal power equipment. During the use of industrial boilers, combustion will produce a large amount of waste gas, which not only contains a large amount of dust and impurities, but also contains a large number of heat sources. Reasonable use of waste heat in high-temperature flue gas can save a lot of resources. Existing The flue gas waste heat utilization rate of the advanced recovery device is low, and when recovering waste heat, the flue gas contains dust, which cannot recycle the heat of the waste gas well, and some flue gas filters are ...
