Convection type plasma melting furnace for hazardous waste treatment

Abstract

The invention discloses a convection type plasma melting furnace for hazardous waste treatment, and relates to the technical field of plasma melting furnaces, the plasma melting furnace comprises a melting furnace body, a plasma torch is arranged at the bottom of the melting furnace body, an air blowing pipeline is arranged above the plasma torch, a feeding port and a synthesis gas outlet are formed in the top end of the melting furnace body, and the feeding port is communicated with the synthesis gas outlet. A feeding pipe is arranged below the feeding port, a slag outlet is formed in the bottom end of the melting furnace body, the synthesis gas outlet is connected with a purification box through a communicating pipe, a one-way vibration mechanism is arranged in the purification box, and one-way circulation of synthesis gas can be guaranteed through the one-way vibration mechanism; and the synthetic gas entering the purification box is prevented from flowing back into the melting furnace body through other communicating pipelines, meanwhile, the whole purification box can vibrate, and the situation that hazardous waste dust adheres to the surface of the purification filtering box, and the filtering effect of the purification filtering box on the synthetic gas is affected is avoided.

Description

Technical field [0001] The invention involves the technology field of plasma melting furnaces, which is specifically a type of plasma melting furnace for hazardous waste treatment. Background technique [0002] Plasma is also called plasma, which is formed by giving enough energy to exert sufficient energy to the gas. It is an ionized gas -like substance composed of positive and negative ions generated by some electrons after being divided by electrons. It is often regarded as the fourth state of material; [0003] Like a hazardous waste refers to hazardous waste. The accumulation of hazardous waste will destroy the ecological environment, affect human health, and restrict sustainable development. Therefore, it is particularly important for the treatment of hazardous waste; [0004] The melting treatment of hazardous waste using plasma is an effective way to deal with; [0005] The existing plasma melting furnace has the following problems during use: [0006] 1. When discharge t...

AI Technical Summary

Problems solved by technology

[0006] 1. When the synthetic gas produced after melting is discharged, the synthetic gas often carries some dust-like substances of hazardous waste. When using a clean box to purify it, these dust-like hazardous waste will stick to the clean box Inside, it affects the normal purification and filtration of synthetic gas by the purification box;

[0007] 2. During the feeding process, the hazardous waste and the synthetic gas generated after melting are located inside the melting furnace at the same time, which will cause the synthetic gas to carry too much hazardous waste dust into the purification box;
