Embodiment Construction

[0013] An integrated organic solid waste incineration device and method is composed of an incineration device 3 , a convertible heat exchanger 4 , an area regulator 5 , a high-temperature dust removal device 6 , a waste heat boiler 7 and a power generation device 8 . The organic solid waste is fed into the incineration device 3 through the feeder 1, and at the same time, the bottom of the incineration device 3 is fed with a combustion aid such as air, oxygen or a mixture of the two, and the organic solid waste is in contact with the combustion aid at the bottom of the incineration device 3 Combustion starts, and the high-temperature flue gas produced after full combustion is discharged from the upper outlet of the incinerator 3 into the convertible heat exchanger 4, which is controlled by the area regulator 5 to adjust the high-temperature flue gas and the convertible heat exchanger 4 heat exchange area, and then control the temperature of the flue gas entering the high-tempera...

Abstract

The invention relates to an organic solid rubbish combustion integration device and an organic solid rubbish combustion integration method. The organic solid rubbish combustion integration device is mainly composed of a combustion device, a variable heat exchanger, an area adjuster, a high temperature dust extraction device, a waste heat boiler and a power generation device. The organic solid rubbish combustion integration method includes the steps that organic solid rubbish is fed into the combustion device through a feeder, and simultaneously combustion agents are input into the bottom of the combustion device, high temperature flue gas generated after the rubbish fully burns is exhausted out from an outlet at the upper end of the combustion device, and then enters the variable heat exchanger, the variable heat exchanger is controlled through the area adjuster and used to adjust the heat exchange area between the high temperature flue gas and the variable heat exchanger, and then controls temperature of the high temperature flue gas which enters the high temperature dust extraction device, the high temperature flue gas enters the high temperature dust extraction device for purification treatment after the high temperature flue gas passes through the variable heat exchanger, and finally gas obtained after the high temperature flue gas is purified enters the waste heat boiler and used by the power generation device to generate power.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to an integrated device and method for organic solid waste incineration, especially for organic solid waste including biomass waste, animal manure, food production waste, industrial organic waste, wood processing production waste, domestic Garbage and other solid wastes are incinerated and transformed into one, realizing near-zero discharge of pollutants, and recovering energy for recycling. Background technique [0002] There are many kinds of organic solid waste. With the development of society, its output is also increasing day by day. Organic solid waste generally contains high calorific value and can be used as a fuel with low calorific value to replace coal, thereby reducing the consumption of coal and saving resources. It is of great importance. Energy recovery value. Commonly used methods for the harmless treatment of organic solid waste include: landfill...
