Garbage gasification furnace with detection device

Abstract

The invention belongs to the technical field of garbage incineration, in particular to a garbage gasification furnace with a detection device, which comprises a barrel-shaped housing, wherein the upper side of the housing is provided with a material input and a smoke outlet, the lower side of the housing is provided with a slag discharge opening, the middle or the lower part of the housing is filled with fluidified sand, an air diffusing tube passes into the inner side from the outer side of the housing, and is then buried in the fluidified sand, the air inlet end of the air dispersing tube, which is positioned at the outer side of the housing, is connected with an air heating furnace, the tube body of the air diffusing tube, which is positioned at the inner side of the housing, is provided with air dispersing holes, the air heating furnace and the air diffusing tube are matched so that the fluidified sand is in a static and deposited state or boiled and fluidified state, and the housing is provided with a temperature detection device and / or pressure detection device. In the invention, garbage pre-treatment can be easily carried out, and the garbage incineration and gasification are carried out, so that the garbage can prevented from being fusty and dispersed, the slag discharge and transmission workload after the garbage incineration and gasification is reduced, combustible gas sources are provided for other incineration furnaces or cement kilns, and the post-treatment of the garbage incineration is facilitated.

Description

technical field [0001] The invention belongs to the technical field of garbage incineration, and in particular relates to a garbage gasifier with a detection device. 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 ...

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 the calorific value of domestic waste in our country is low, and the non-combustible components in the waste may affect the quality of cement, domestic waste in our country cannot be directly incinerated in cement kilns, which seriously hinders the recycling of waste.
