Abstract

The invention relates to a hot water recirculation system used for flue gas waste heat recovery, and relates to the field of thermal power generation energy conservation. The hot water recirculation system comprises a boiler body and a flue gas waste heat recovery shell body installed on the boiler body, the flue gas waste heat recovery shell body communicates with the boiler body through a gas inlet pipe, a gas outlet pipe is fixedly connected to the top of the flue gas waste heat recovery shell body, a filtering piece is installed at a pipe opening of the gas outlet pipe, a cleaning component used for cleaning the filtering piece is installed on the gas outlet pipe, the cleaning part comprises a fixed plate which is fixedly connected to the inner wall of the air outlet pipe, a rotating shaft which is rotationally installed on the fixed plate and a scraping plate which is installed on the rotating shaft, the side wall of the scraping plate makes contact with the side wall of the filtering piece, and a driving part used for driving the rotating shaft to rotate is installed on the air outlet pipe. Through the hot water recirculation system, the problem that filtering holes in the filtering piece are prone to being blocked is solved.

Description

technical field [0001] The present application relates to the field of energy saving of thermal power generation, in particular to a hot water recirculation system for recovery of waste heat from flue gas. Background technique [0002] At present, coal price is the main factor affecting the economic benefits of coal-fired power plants. The flue gas waste heat recovery system can save the coal consumption of power generation because it can recover the waste heat from the boiler exhaust. At present, it has become a standard equipment in new coal-fired power generation units in my country, and the old power generation units are gradually undergoing energy-saving retrofitting and installing this system. [0003] Related technologies can refer to the Chinese utility model patent with the notification number CN212512629U, which discloses a flue gas waste heat recovery device, including a water storage bucket, a flue gas waste heat recovery shell, and an operating table. The water...
