Clean and efficient garbage incineration power generation system

Abstract

The invention discloses a clean and efficient garbage incineration power generation system. The clean and efficient garbage incineration power generation system comprises a garbage drying device, a grate furnace, a steam pocket, a steam turbine and a power generator which are sequentially connected; the garbage drying device comprises a garbage dewatering box, a garbage drying box is arranged below the garbage dewatering box, and a garbage conveying and preheating channel which is obliquely distributed is arranged between the garbage dewatering box and the garbage drying box; the garbage dewatering box comprises a dewatering outer barrel, a dewatering rotating rod is arranged in the middle of the interior of the dewatering outer barrel, a driving motor is arranged at the upper end of the dewatering rotating rod, a rotating assembly is arranged on the dewatering rotating rod, a water filter screen which is obliquely distributed is arranged at the bottom of the dewatering outer barrel, and the water filter screen is matched with the garbage conveying and preheating channel; and the rotating assembly comprises a plurality of vertical plates annularly distributed on the dewatering rotating rod, and a vertical moving mechanism is arranged between the vertical plates and the dewatering rotating rod. The power generation system has the characteristic that the combustion efficiency can be effectively improved.

Description

technical field [0001] The invention relates to a waste incineration power generation system, in particular to a clean and efficient waste incineration power generation system. Background technique [0002] The thermal power plant uses the boiler to burn garbage, coal and other substances to generate steam, and then drives the generator set to move to complete the power generation process, mainly including the grate furnace, steam drum, steam turbine and generator set. The garbage is burned in the combustion chamber of the grate furnace. After the heat exchange of the heat exchanger in the combustion chamber of the grate furnace, steam is generated and enters the steam drum, and then the steam drives the steam turbine to operate, and then drives the generator set to generate electricity. However, because the garbage contains more moisture, although most of the filtrate will be filtered out after screening, there will still be a certain amount of moisture in the garbage. When...

Problems solved by technology

However, because the garbage contains more moisture, although most of the filtrate will be filtered out after screening, there will still be a certain amount of moisture in the garbage. When the garbage containing moisture is directly sent into the grate furnace for burning , will lead to a reduction in combustion efficiency, and the moisture in the garbage needs to be dried before it can be burned, which in turn will affect the overall power generation efficiency

Therefore, the existing technology has the problem of low combustion efficiency
