Problems solved by technology
Due to the large amount of dust, the waste heat of the flue gas before dust removal in the power plant is likely to cause blockage and wear to the equipment, so the relevant heat is difficult to recover and utilize
The traditional tubular heat exchanger has low heat exchange efficiency and bulky volume, and at the same time, it is difficult to clean the blockage after operation, and it is difficult to maintain, so it cannot guarantee long-term normal operation

The invention discloses an anti-blocking high-efficiency heat recovery heat exchanger. The heat exchanger is characterized by comprising a heat exchanger frame, wherein the top of the heat exchanger frame is provided with a flue gas side inlet assembly, the bottom of the heat exchanger frame is provided with a flue gas side outlet assembly, the flue gas side inlet assembly and the flue gas side outlet assembly are provided with a flue gas inlet and a flue gas outlet, the left side and the right side of the heat exchanger frame are respectively provided with an air side assembly, each air side assembly is provided with an air inlet / outlet, the two air inlets / outlets located in the left side and the right side are oppositely arranged in the left-right direction, and N groups of upper plate assemblies which are stacked up and down, M groups of middle plate assemblies which are stacked up and down and K groups of lower plate assemblies which are stacked up and down are sequentially arranged in the heat exchanger frame from top to bottom. According to the anti-blocking high-efficiency heat recovery heat exchanger, on the basis that an existing boiler system is not integrally changed, operation is safe and reliable, influences on other equipment and the whole system are avoided, and the purposes of energy conservation and emission reduction are achieved.
Description
technical field [0001] The invention relates to an anti-blocking high-efficiency heat recovery heat exchanger, which belongs to the fields of flue gas / waste gas environmental protection and energy saving. Background technique [0002] At present, boilers in power plants generally use tubular economizers to increase the temperature of fresh air entering the boilers to achieve energy-saving purposes. However, due to the low heat transfer efficiency and bulky size of the tubular economizer, the original flue gas temperature still has a large amount of heat that cannot be fully recovered, resulting in a large loss of heat energy. When heating in winter, due to heating needs, the load will increase, and the unused waste heat of flue gas will be more. [0003] The flue gas heat exchanger with plate structure is a new type of flue gas heat exchanger structure, which has the characteristics of small size, light weight, high heat exchange efficiency, easy installation, easy maintena...
