Technical Field

[0002] Incineration is a high-temperature heat treatment technology, that is, a certain amount of excess air is used to carry out oxidation combustion reaction with the treated organic waste in the incinerator, and the harmful and toxic substances in the waste are oxidized and pyrolyzed at high temperature and destroyed. It is a treatment technology that can simultaneously achieve harmlessness, reduction and resource utilization of waste. Excess air supply is an important control parameter in the waste incineration process. The appropriate amount of air volume and reasonable air intake layout can effectively improve the efficiency of air distribution.

[0003] The incinerator used in the incineration system of solid waste, waste liquid and waste gas adopts a specially designed air supply design, which can effectively improve the incineration efficiency of the incinerator. The incineration temperature is above 1100℃, and the excess combustion air required for material incineration is introduced into the incinerator. The conventional way of introducing air is to open one or two vents directly on the furnace wall, and use the lift of the fan to directly introduce air or waste gas into the furnace.

[0004] The above method can only open air holes at one or two points to allow air to enter the furnace. The air entering the furnace is unevenly mixed with the flue gas burned in the furnace, resulting in a low degree of waste incineration in the incinerator and a high CO content generated by the incinerator, which has an adverse impact on the environment.
