Garbage gasification furnace

Abstract

The invention belongs to the technical field of refuse burning, and in particular relates to a garbage gasification furnace. The garbage gasification furnace comprises a cannular shell, the upside of the shell is respectively provided with a material feeding inlet and a smoke outlet, the lowerside of the shell is provided with a slagging port, and the middle-lower part of shell is filled with fluidization sands; a disperse air pipe penetrates the inner side of the shell from the outside of the shell so as to be buried in the fluidization sands, the air inlet end of the disperse air pipe positioned outside the shell is connected with a hot-air oven, and a disperse air hole is formed on the pipe body of the disperse air pipe inside the shell; the hot-air oven and the disperse air pipe are matched to lead the fluidization sands to be in a static deposition state or a boil fluidized state. The garbage gasification furnace provided by the invention has the advantages of easily carrying outthe garbage pretreatment, burning and gasifying the garbage, preventing the effluvium spreading of the garbage, reducing the deslagging and slag-carrying workload of the garbage after burning aerification, providing a flammability air source for other incinerators or cement kilns, and being beneficial to the later processing of the refuse burning.

Description

technical field [0001] The invention belongs to the technical field of garbage incineration, and in particular relates to a garbage gasifier. Background technique [0002] Judging from the application of the existing waste incineration technology in my country, there are mainly the following problems: the main component of domestic waste in my country is unsorted kitchen waste, and at the same time, due to the serious stench of kitchen waste, it is difficult to sort it again The selection is more difficult; and the seasonal variation of the calorific value of the garbage is larger and the moisture content of the garbage is higher. [0003] Because domestic waste is mainly kitchen waste, and plastic, waste paper and other high calorific value waste is less, the calorific value of domestic waste in our country is low, and it is difficult to adapt to the incinerator with higher working temperature imported from abroad. In order to ensure the incineration The incinerator can wor...

Problems solved by technology

[0002] Judging from the application of the existing waste incineration technology in my country, there are mainly problems in the following aspects: the main component of domestic waste in my country is unsorted kitchen waste, and at the same time, due to the serious stench of kitchen waste, it is difficult to sort it again. The selection is more difficult; and the calorific value of the garbage varies greatly seasonally and the moisture content of the garbage is higher

[0003] Because domestic waste is mainly kitchen waste, and plastic, waste paper and other high calorific value waste is less, the calorific value of domestic waste in our country is low, and it is difficult to adapt to the incinerator with higher working temperature imported from abroad. In order to ensure the incineration The furnace can work stably and smoothly, so it is necessary to add more fuel to the incinerator, resulting in a waste of fuel; and although there are many types of incinerators developed by our country, and some of them are suitable for incineration of domestic garbage, However, its incineration temperature is relatively low. For example, most incinerators can only reach an incineration temperature of 600-800 ° C. Because the waste in this temperature range will produce a large amount of dioxins and furans, and the gas will not be completely burned. Contains a large amount of organic matter, so the pollution to the atmospheric environment is relatively serious

[0004] At the same time, because of the low calorific value of domestic waste in our country, domestic waste in our country cannot be directly incinerated in cement kilns, which seriously hinders the recycling of waste.
