Plasma waste incinerator and incineration system thereof

Abstract

The invention provides a plasma waste incinerator and an incineration system thereof. The incinerator comprises an incinerator body, the top of the incinerator body is provided with a plasma torch, the plasma torch comprises a pipe body, and the pipe body is internally provided with a positive electrode and a negative electrode; an ionization cavity is formed in the center of the positive electrode, the upper portion of the ionization cavity is provided with an inverted conical groove, and the conical groove is internally provided with a gas guide block; the negative electrode penetrates through the gas guide block and extends to the upper portion of the ionization cavity; the system comprises a first combustion chamber, the plasma waste incinerator, a heat exchanger, an extremely cold spraying system, a cloth bag dust removal device and a filtration device which are connected sequentially; according to the incinerator, by using the gas guide block, it is ensured that the heat is centralized at a point efficiently during gas ionization, the high efficiency is ensured, and the service life of the plasma torch is greatly prolonged; the incineration system is used for quickly decomposing and destroying treated objects, wherein organic matter is pyrolyzed into flammable small-molecular substances, and inorganic matter is subjected to high-temperature melting to generate glass-similar residues.

Description

technical field [0001] The invention relates to the field of garbage treatment, in particular to a plasma garbage incinerator and an incineration system thereof. Background technique [0002] Existing waste disposal systems usually use methods such as ordinary incineration and burial. This method of waste disposal, especially for low- and medium-level radioactive waste, medical waste, and urban waste, has secondary pollution, complex processes, and selective waste disposal. However, in the existing plasma treatment equipment, such as the invention patent with the patent announcement number of CN 103493601B, a plasma torch is disclosed, which uses a ceramic coating layer as a diversion bushing, the ionization effect is poor, and the service life of the electrode is relatively short, basically about 6 days. Another example is the invention patent of CN103503579B, which discloses a high-performance induction plasma torch. There is a problem that the anode position will be corr...

[0002] Existing waste disposal systems usually use methods such as ordinary incineration and burial. This method of waste disposal, especially for low- and medium-level radioactive waste, medical waste, and urban waste, has secondary pollution, complex processes, and selective waste disposal. However, in the existing plasma treatment equipment, such as the invention patent with the patent announcement number of CN 103493601B, a plasma torch is disclosed, which uses a ceramic coating layer as a diversion bushing, the ionization effect is poor, and the service life of the electrode is relatively short, basically about 6 days. Another example is the invention patent of CN103503579B, which discloses a high-performance induction plasma torch. There is a problem that the anode position will be corroded due to ionization reaction, the service life is low, and the combustion efficiency is low
