Environment-friendly ultra high temperature oxidation and catalyzation furnace

Abstract

The invention discloses an environment-friendly ultra high temperature oxidation and catalyzation furnace which comprises a furnace body and a furnace bottom, wherein a combustion cavity is arranged in the furnace body; a feed opening, a flue gas outlet and a main air inlet pipe are arranged on the furnace body; the combustion cavity comprises a combustion chamber, an oxidative combustion chamber and a catalyzation chamber; a main annular air chamber, a primary air intake chamber, a secondary air intake chamber and a catalyzation air chamber are arranged on the furnace casing in sequence from bottom to top; one side of the main annular air chamber communicates with the main air inlet pipe; the main annular air chamber communicates with the primary air intake chamber, the secondary air intake chamber and the catalyzation air chamber through a communication channel; and an air inlet pipe communicating with each of the combustion chamber, the oxidative combustion chamber and the catalyzation chamber correspondingly is distributed on the inner wall of each of the primary air intake chamber, the secondary air intake chamber and the catalyzation air chamber in the circumferential direction. According to the environment-friendly ultra high temperature oxidation and catalyzation furnace, the combustion at the temperature of 1100 DEG C or above is realized, through the combustion, oxidation and catalyzation processes, organic wastes are sufficiently combusted, the emission of harmful gases is reduced, the furnace bottom can be quickly replaced when the combustion is conducted in the furnace body, and the combustion waste utilization rate of the furnace body is improved.

Description

technical field [0001] The invention belongs to the technical field of organic waste treatment equipment, in particular to an ultra-high temperature oxidation catalytic environmental protection furnace. Background technique [0002] With the rapid development of modern industry, and the increase of electronic appliances and automation control in daily life, the waste of metal and organic combination in various industries has also increased rapidly. Metal and organic wastes are burned to extract metal substances, which will produce a large amount of toxic gas of dioxins and discharge them into the atmosphere, causing serious air pollution and endangering the daily life and health of residents. At present, the incinerator for metal-organic waste usually includes a furnace body and a furnace bottom. The bottom has the function of supporting the above-mentioned furnace body. Once the furnace bottom is replaced, the furnace body needs to be extinguished, cooled, cleaned, and rep...

Problems solved by technology

Metal and organic wastes are burned and incinerated to extract metal substances, which will produce a large amount of toxic gases of dioxins and discharge them into the atmosphere, causing serious air pollution and endangering the daily life and health of residents.

At present, the incinerator for metal-organic waste usually includes a furnace body and a furnace bottom. The bottom has the function of supporting the above-mentioned furnace body. Once the furnace bottom is replaced, the furnace body needs to be extinguished, cooled, cleaned, and replaced. Therefore, it takes at least two or three days to replace the furnace bottom once, which wastes organic waste. In addition, the combustion temperature of the furnace body in the prior art is limited, the organic waste is usually incompletely burned, and a large amount of sulfur and nitrogen harmful gases such as nitric oxide and sulfur dioxide are discharged
