Combustion furnace tube type air distribution device

Abstract

The invention discloses a combustion furnace tube type air distribution device which comprises a shell, and the shell is provided with a closed circular cavity tubular air duct. At least one air inlet is formed in the upper surface or the side surface of the shell, the air inlet is communicated with the circular cavity tubular air duct, and hearth distributed air enters the circular cavity tubular air duct through the air inlet; at least one tuyere is arranged in the circular cavity tubular air duct, and the circular cavity tubular air duct surrounds to form an inner circular flame passing channel used for outputting combustion flames of a hearth. Air distribution outside the combustion furnace is fed into the air inlet through the air distribution pipe, after the air distribution enters the circular cavity tubular air duct, the air distribution outside the combustion furnace is evenly blown into the hearth through the tuyere arranged in the circular cavity tubular air duct, cyclone fire is formed in the hearth, and fuel in the hearth is rapidly heated. The combustion temperature of the hearth is increased, fuel in the hearth is combusted more sufficiently, and energy is saved; and the air distribution amount in the hearth can be adjusted according to the hearth combustion condition.

Description

technical field [0001] The invention relates to the technical field of environmental protection and energy saving and the technical field of stoves, in particular to a tube-type air distribution device for a combustion furnace used in an environmental protection furnace. Background technique [0002] At present, the traditional combustion heating stoves on the market are basically negative pressure stoves, which use high-level chimneys to naturally draw air for auxiliary combustion, and some use positive pressure to blow air from the lower part of the furnace, and the negative pressure furnace has low temperature and insufficient combustion. , the discharge is difficult to meet the standard, the pollution is serious, the positive pressure furnace is hot, the temperature control is difficult, the environmental protection treatment after discharge is complicated, and the production cost is high. Therefore, there are still many thorny problems in environmental protection and ene...

Problems solved by technology

[0002] At present, the traditional combustion heating stoves on the market are basically negative pressure stoves, which use high-level chimneys to naturally draw air for auxiliary combustion, and some use positive pressure to blow air from the lower part of the furnace, and the negative pressure furnace has low temperature and insufficient combustion. , the discharge is difficult to meet the standard, the pollution is serious, the positive pressure furnace is hot, the temperature control is difficult, the environmental protection treatment after discharge is complicated, and the production cost is high. Therefore, there are still many thorny problems in environmental protection and energy saving. The effect of environmental protection and energy saving is poor, large-scale production cannot be realized, and the popular demand of the market cannot be met. Therefore, these problems existing in today's combustion heating stoves are solved, and the technical development bottleneck of traditional heating stoves is broken. Common challenges faced by the hot water heater, commercial boiler and industrial boiler industry
