Plasma refuse incinerator

Abstract

The invention discloses a plasma garbage incinerator. An electrode is respectively arranged at the bottom and top parts of the incinerator body; the electrodes at the bottom and top parts are respectively connected with the anode and cathode of high voltage DC power supply; the electrode at the bottom part is clamped by an electrode holder and driven to move from up to down by an electrode lifting device. When in work, two electrodes and the high voltage DC power supply are conducted and the electrode lifting device is regulated so as to cause the electrode at the top part to be lowered and contact with the electrode at the bottom part and then gradually pulled away, which can cause an arc column to be generated between two electrodes; the temperature of the arc column is extremely high, with the center temperature up to 20,000 DEG C; under the action of the Lorentz force, the plasma arc column has the trend to contract towards the center and thus generates suction effect; under the action of the suction effect, the garbage thrown in the hearth can be quickly inhaled into the arc column and then incinerated, with the burning temperature up to 6000 DEG C. The burning temperature is high, so the garbage can be fully incinerated; as the rate of capacity reduction after incineration is high, the ash is less and no unburned substance containing remnants is left, so the environment can not be polluted and the ash can be handled conveniently; the invention can be used for processing the dangerous goods waste, the medical waste and the radioactive waste garbage, etc.

Description

technical field [0001] The invention relates to a garbage incineration device, in particular to a plasma garbage incinerator which utilizes a plasma arc to incinerate garbage. technical background [0002] Existing waste incinerators usually mainly include grate type incinerators, hearth type incinerators, fluidized bed type incinerators, and pyrolysis incinerators, etc., which incinerate waste through the combustion method, and the temperature of waste incineration is relatively low , usually can only reach about 1000 ℃, and its garbage is difficult to burn out completely, and there will be residual incompletely burned substances in the slag, and these remaining substances will be dissolved out again to pollute the environment after being discharged with the slag. At the same time, the incomplete combustion of the garbage also leads to a low volume reduction rate after combustion, usually only 80%-90%. The slag of the material has the possibility of polluting the environme...

Problems solved by technology

[0002] Existing waste incinerators usually mainly include grate type incinerators, hearth type incinerators, fluidized bed type incinerators, and pyrolysis incinerators, etc., which incinerate waste through the combustion method, and the temperature of waste incineration is relatively low , usually can only reach about 1000°C, the garbage is difficult to burn out completely, and there will be residual incompletely burned substances in the slag, and these remaining substances will dissolve again to pollute the environment after being discharged with the slag

At the same time, the incomplete combustion of the garbage also leads to a low volume reduction rate after combustion, usually only 80%-90%. The slag of the material may pollute the environment again. In order to avoid its pollution to the environment, it usually needs to be buried. The disposal of the slag is troublesome and requires special land resources.

[0003] In addition, the garbage cannot be completely burned, which also limits the types of garbage that the above-mentioned existing garbage incinerators can handle. For hazardous waste, medical waste, radioactive waste, etc., only a small amount of untreated waste remains could have a significant impact on the environment

In addition, in the above-mentioned existing garbage incinerators, when disposing of garbage, it takes a long time for the garbage to burn and heat up. During the heating process, a certain amount of highly toxic gases such as dioxins that are harmful to the human body will be produced, which will bring harm to the health of the operators. harm
