Description

technical field [0001] The invention relates to the technical field of high-temperature flue gas waste heat utilization, in particular to a high-temperature flue gas waste heat utilization device for a biogas generating set. Background technique [0002] The biogas generator set is a kind of mechanical equipment that relies on biogas to generate electricity. The biogas generator set compresses the mixture of "air biogas" in the cylinder, burns it with a spark plug, obtains power through the reciprocating motion of the piston, and then connects the generator to generate electricity. It has the advantages of convenient control and good economy. During the working process of the biogas generator set, high-temperature flue gas will be generated. The high-temperature flue gas contains a lot of energy. An effective means of utilization, flue gas waste heat is generally used by replacing the heat in the flue gas with other media through the flue gas heat exchanger, and the waste he...

[0002] The biogas generator set is a kind of mechanical equipment that relies on biogas to generate electricity. The biogas generator set compresses the mixture of "air biogas" in the cylinder, burns it with a spark plug, obtains power through the reciprocating motion of the piston, and then connects the generator to generate electricity. It has the advantages of convenient control and good economy. During the working process of the biogas generator set, high-temperature flue gas will be generated. The high-temperature flue gas has a lot of energy. An effective means of utilization, flue gas waste heat is generally used by replacing the heat in the flue gas with other media through the flue gas heat exchanger, and the waste heat utilization of the flue gas is mostly realized through waste heat boilers. During use, it is found that the flue gas contains a large amount of dust. During use, the dust will accumulate in the waste heat boiler, affecting the working efficiency of the waste heat boiler, reducing the waste heat utilization rate of the flue gas, and wasting resources.
