Problems solved by technology

[0002] In the process of using incineration to dispose of hazardous waste, hazardous waste is pyrolyzed and burned in the incinerator, and the flue gas generated in the incinerator contains a large amount of combustible gas, and such flue gas will cause air pollution if it is directly discharged into the atmosphere. Pollution, heat energy is not fully released and utilized, and does not meet the requirements of harmless and resourceful disposal of hazardous waste. Therefore, the process requires the incineration system to have equipment for secondary combustion of flue gas, that is, the secondary combustion chamber

Abstract

The invention relates to a secondary combustion chamber for hazardous waste incineration disposal. By means of the technical scheme, the secondary combustion chamber is characterized by comprising a base shell, a refractory layer attached to the inner wall of the base shell, a furnace shell arranged on the outer layer of the base shell, and a combustion air assembly assembled on the furnace shelland communicating with the interior of the base shell, the base shell is in a dumbbell shape and comprises a hearth upper portion, a hearth throat portion and a hearth lower portion, a smoke inlet isformed in the top end of the hearth upper portion, and a smoke outlet is formed in the bottom side of the hearth lower portion, Thus, the volume of a hearth is not increased, meanwhile the time of smoke staying in a furnace is prolonged, the aim of sufficiently burning out combustible matter in smoke under a relatively-low air excess coefficient is realized, the structure is simple, manufacturingcost can be easily reduced, the time of equipment from startup to normal operation is shortened, and consumption of auxiliary fuel is reduced.

Description

technical field [0001] The invention relates to the technical field of waste incineration, in particular to a secondary combustion chamber used for incineration and disposal of hazardous waste. Background technique [0002] In the process of using incineration to dispose of hazardous waste, hazardous waste is pyrolyzed and burned in the incinerator, and the flue gas generated in the incinerator contains a large amount of combustible gas, and if such flue gas is directly discharged into the atmosphere, it will cause air pollution. Pollution, heat energy is not fully released and utilized, and does not meet the requirements of harmless and resourceful disposal of hazardous waste. Therefore, the process requires the incineration system to have equipment for secondary combustion of flue gas, that is, the secondary combustion chamber. The requirements for the secondary combustion chamber are that the furnace temperature is higher than 850°C, the residence time of the flue gas in ...
