Plasma incineration waste treatment equipment

Abstract

The invention discloses plasma incineration waste disposal equipment. The waste feed inlet of a plasma waste incinerator is connected with a waste pre-heating device; the feed entrance of the pre-heating disposal device is connected with a waste crushing device; the waste pre-heating device is provided with an exhaust pipeline for mixed waste gas which is communicated with the combustion chamber of a steam boiler; the steam pipeline of the steam boiler is communicated with steam generating equipment and transmits steam to the steam generating equipment for generating power. Before entering the plasma waste incinerator, the waste is not only crushed into small pieces, but also is preheated for evaporating bulk of the moisture, so the waste entering the incinerator has small volume and less moisture, the possibility for rapidly generating excessive mixed gas and thus resulting in explosion under instant high temperature as the waste contains much water can not be generated, and the security performance is good. Meanwhile, the waste can produce a large amount of combustible mixed gas such as CO and the like in preheating, the mixed gas is conducted into the steam boiler for being incinerated and generating steam by heating, and the hot steam is transmitted into the steam generating equipment for doing work and generating electric energy which can be used for providing the electric energy that is needed by the plasma waste incinerator when in work, so the electricity consumption of the plasma incineration waste disposal equipment is also reduced.

Description

technical field [0001] The invention relates to garbage incineration treatment equipment, in particular to plasma incineration garbage treatment equipment. technical background [0002] The existing waste incineration treatment equipment usually incinerates waste mainly through the combustion furnace in the equipment. The temperature of the waste incineration is relatively low, usually only reaching about 1000°C, and the waste is often unable to be completely burned. There will be incompletely burned components remaining in the slag, and there is still a certain pollution to the environment. It cannot be used to treat medical waste, animal carcasses, chemical waste, electronic waste, dangerous goods waste and other wastes that are not allowed to remain in the slag. . In order to deal with the above-mentioned special garbage, plasma incineration garbage treatment equipment has a good prospect as a new kind of garbage treatment equipment. The incineration temperature range c...

Problems solved by technology

However, in the existing plasma incineration garbage treatment equipment, the garbage is usually directly poured into the plasma incineration garbage furnace for high-temperature incineration without treatment. The poured garbage will instantly heat up, and the liquid in it will instantly vaporize and expand, causing Partial explosion may cause damage to the furnace body or electrodes of the incinerator, especially for waste with a lot of water, the impact on the furnace body and electrodes is particularly serious, such as liquid injection bottles or liquid medicine bottles in medical waste.

In addition, the electrodes of the plasma incineration garbage furnace of the existing plasma incineration garbage treatment equipment need to be connected to a high-voltage DC power supply, and the incineration process consumes a large amount of electric energy and consumes a lot of electricity
