Incineration method for domestic, medical and building solid waste

Abstract

The invention discloses an incineration method for domestic, medical and building solid waste. A fixed smoke baffle is vertically arranged at the joint of an upper chamber and a lower chamber. The upper end of the fixed smoke baffle is fixed to the inner top surface of the lower chamber, and a waste passing port for allowing the waste to pass is reserved between the lower end of the fixed smoke baffle and the bottom surface of the upper chamber. A waste inlet pipe is arranged at the top of the upper chamber, and a discharge outlet of the waste inlet pipe communicates with a feed inlet of the top of the upper chamber. A set of burning nozzles are densely arranged on the inner wall of the lower chamber, the uppermost burning nozzles are close to the lower end of a movable smoke baffle, and the bottommost burning nozzles are located at the bottom of the lower chamber. Air nozzles are densely arranged on the inner bottom surface of the lower chamber, are vertically disposed and spay air upwards, and the same air pump arranged outside a furnace body supplies air to all the air nozzles through an external pipeline. By means of the method, sufficient waste incineration is guaranteed, meanwhile, the effect that the waste is pre-dried by high-temperature hot air is improved, and the environmental-friendly performance is good.

Description

technical field [0001] The invention relates to a waste incineration device, in particular to an incineration method for treating domestic, medical and construction solid waste. Background technique [0002] Garbage disposal has always been a major environmental issue of concern to the world. The existing solid waste can be mainly divided into domestic, medical and construction waste. Traditional solid waste disposal methods mainly include landfill and incineration. Landfill will occupy a lot of valuable land resources and pollute the environment at the same time, so this simple treatment method is basically no longer used. Compared with landfill treatment, waste incineration is a better treatment method. Through incineration, not only garbage The volume is greatly reduced, and at the same time, the heat generated by incineration can be used to generate electricity and heat, so as to achieve the purpose of energy reuse. [0003] Therefore, incineration technology has becom...

Problems solved by technology

[0005] Although the above-mentioned patented technology can use high-temperature flue gas to dry wet garbage to a certain extent, it has been found through experiments that the drying effect of the above-mentioned structure is not good, and the garbage at the raking rod still has a certain amount of moisture, and these moisture-containing garbage enters the furnace body The incineration in the furnace cavity will be insufficient in the future, which will not only produce a large amount of gas, but also lead to insufficient incineration, which will reduce the amount of high-temperature flue gas, resulting in a reduction of high-temperature flue gas introduced into the garbage drying box, which will in turn which in turn reduces the drying effect

[0006] When the garbage is raked into the furnace cavity, it is piled up layer by layer on the rake-shaped grate at the bottom of the furnace cavity, and is ignited by the combustion nozzle at the grate and then burned. After actual use, it is found that the garbage accumulates on the grate There is also the phenomenon of insufficient incineration, which will not only produce a large amount of toxic fumes, poor environmental performance, but also reduce the amount of high-temperature fumes, which will in turn reduce the drying effect
