Garbage combustion power generation device with tail gas treatment function

Abstract

The invention discloses a garbage combustion power generation device with a tail gas treatment function, which relates to the technical field of garbage combustion power generation, and comprises a combustion furnace used for receiving garbage from a temporary storage tank and combusting the garbage; a smoke exhaust pipe which is communicated with the top of the combustion furnace; a steam power generation mechanism, wherein a gas inlet end of the heating surface of the steam power generation mechanism is communicated with the smoke exhaust pipe through a gas inlet head, and a gas outlet end of the heating surface of the steam power generation mechanism is connected with at least two tail gas treatment mechanisms in parallel through a gas outlet head; and the tail gas treatment efficiencies of all the tail gas treatment mechanisms are different.

Description

technical field [0001] The invention relates to the technical field of garbage combustion power generation, in particular to a garbage combustion power generation device with tail gas treatment. Background technique [0002] At present, the treatment of garbage includes landfill, composting and incineration for power generation. Among them, incineration for power generation is widely used because of its small footprint, short treatment cycle, and good capacity reduction effect. The existing incineration for power generation includes mechanical grate Incinerator equipment, by dumping garbage into the incinerator, the combustion air enters from the lower part of the grate and mixes with the garbage. The high-temperature flue gas passes through the heating surface of the boiler to generate hot steam, and the flue gas is also cooled at the same time. Finally, the flue gas is discharged. However, at present, the existing waste incineration power generation equipment has average o...

[0002] At present, the treatment of garbage includes landfill, composting and incineration for power generation. Among them, incineration for power generation is widely used because of its small footprint, short treatment cycle, and good capacity reduction effect. The existing incineration for power generation includes mechanical grate Incinerator equipment, by dumping garbage into the incinerator, the combustion air enters from the lower part of the grate and mixes with the garbage. The high-temperature flue gas passes through the heating surface of the boiler to generate hot steam, and the flue gas is also cooled at the same time. Finally, the flue gas is discharged. However, at present, the existing waste incineration power generation equipment has average overall economic benefits, and it often cannot make full use of the energy in the waste burning process, thus causing a waste of resources, and the waste is often compressed before incineration, thus Excess liquid is drained, which also causes the subsequent waste to not dry and burn quickly during the incineration process
