Device and method used for improving heat value of waste put into furnace of household waste incineration plant

Abstract

The invention discloses a device and method used for improving the heat value of waste put into a furnace of a household waste incineration plant. The device comprises a waste pond used for containinghousehold waste and performing water draining on the household waste, a guiding and discharging pipe used for discharging leachate in the waste pond, an incinerator used for incinerating the waste after water draining and a grab bucket hoist used for laying the waste in the waste pond or conveying the waste after water draining to the incinerator; and a combustible water draining cushion layer for performing water draining on the household waste is arranged in the waste pond. According to the device and method used for improving the heat value of the waste put into the furnace of the household waste incineration plant, the combustible water draining cushion layer is adopted to perform water draining on the household waste, the leachate which is drained out is filtered by a water guiding filtering grate and is discharged out of the guiding and discharging pipe, on one hand, the process is simple and easy to operate, the water draining effect of the household waste can be improved, it is avoided that because water is not drained out in time, the water content of the waste put into the furnace is high, the heat value of the waste put into the incinerator can be effectively improved,and the incineration work condition is improved.

Description

technical field [0001] The invention belongs to the technical field of domestic waste incineration, and in particular relates to a device and method for increasing the calorific value of waste in a domestic waste incineration plant. Background technique [0002] In recent years, the waste incineration power generation treatment method has developed rapidly in my country and has become one of the main ways to deal with municipal solid waste in our country. At present, domestic garbage in our country is still mainly collected in a mixed manner, and affected by the eating habits of our people, the content of organic perishable garbage in the mixed garbage is mostly between 50% and 70%, and the moisture content is very high, which affects the incineration of garbage. The stability of the working condition. [0003] In the waste incineration plants that have been in operation in my country, in order to increase the calorific value of domestic waste and ensure that the domestic w...

Problems solved by technology

Since the garbage still contains a lot of particulate matter, during the stacking process, the particulate matter gradually moves downward with the water, and finally deposits at the bottom of the garbage dump to form a dense layer. This dense layer accumulates thicker and thicker, and the water in the upper layer of garbage is very It is difficult to go down, making it difficult to drain the moisture in the garbage, and the moisture content of the garbage entering the furnace increases, making it difficult to stabilize the incineration condition
