A method for judging the adequacy of fermentation of waste in a waste incineration plant

Abstract

A method for judging the adequacy of garbage fermentation in a garbage incineration plant, comprising the following steps: the first step: obtaining the calorific value of the incoming garbage; the second step: measuring the length, width and height of the garbage pool of the incineration plant to obtain the volume of the garbage pool; the third step: Obtain leachate information; Step 4: Calculate the degree of fermentation in the area, the calculation method is: fermentation value of each layer in each area = conversion value of garbage entering the pool * 0‑10% + conversion value of storage time * 70 ‑90%+leachate conversion value*10‑30%+area state conversion value*0‑10%+layer state conversion value*0‑10%; step 5: set the area top-clearing fermentation level threshold, when When the fermentation level is higher than the threshold, there is no need to clean the bottom, otherwise the bottom needs to be cleaned; when the fermentation level is higher than the threshold, there is no need to remove the top, otherwise the top needs to be removed. The method for judging the adequacy of fermentation of garbage in a garbage incineration plant provided by the invention can accurately judge the adequacy of fermentation in each area of ​​a garbage pool. It can judge the water content in the area garbage, the best frequency of removing the top and cleaning the bottom, and the best position of grabbing materials.

Description

[0001] A method for judging the sufficiency of waste fermentation in waste incineration plants Technical field [0002] The present invention belongs to the field of waste incineration, relates to a garbage incineration plant waste fermentation sufficiency judgment method. Background [0003] The area of the garbage pond in the waste incineration plant is large, and the degree of waste fermentation will be different in different areas. If the garbage is taken into the furnace in the order of the degree of waste fermentation from high to low, the incinerator combustion will be stable and the pollution will be minimized. [0004] The existing degree of garbage fermentation mainly depends on the experience of the staff to judge, the judgment method only pays attention to the time of garbage into the pool, does not divide the garbage pool into regions, pays attention to a single point, top clears the bottom and grabs the operation at will or judges by experience, the garbage in the re...

AI Technical Summary

Problems solved by technology

The water content of the regional garbage, the frequency of removing the top and cleaning the bottom, and the selection of the location of the material are three factors that play a key role in whether the garbage is fully fermented. The judgment of these three elements is difficult for the staff

The method of manual judgment will lead to incompletely fermented garbage entering the furnace ahead of time, and the calorific value of the garbage entering the furnace is unstable, which will affect the combustion of the incinerator, cause damage to the incinerator, and increase the risk of pollutant discharge
