Weak base water and turbulence sphere are almost finished and have been absorbed dust and harmful substance contained in the flue gas, for the more flue gas of harmful substance contents, after multistage flue gas processing section processing, harmful substance in the flue gas also can be removed fully, therefore, gas through emission abatement is almost colourless, do not contain harmful ingredients, and be better than the discharge standard of GB, treatment effect is good, promptly the harmful substance in the flue gas can be removed through the processing of a treating column, and equipment is simple, reduced investment can be widely used.
Structure of the present utility model can be specially:
Turbulence sphere is a kind of spheroid, this spheroid has two hemisphere, and two hemisphere are made up of the some blades that distribute along warp direction respectively, and the blade of two hemispheres is for being interspersed, be distributed with slotted hole in the axis along warp direction, this slotted hole connects one of them hemisphere and extends to another hemisphere.
Like this, gas shock is on the blade of turbulence sphere, air-flow rolls the turbulent flow body arbitrarily, thereby confuse air-flow, form irregular air motion, air-flow is detained, can fully mix with weak base water and react, be convenient to the removing of the harmful substance in the flue gas, thereby flue gas can be cleaned fully, reaches discharge standard.
The tower body inner chamber has one to level Four flue gas processing section.
Like this, can select multistage flue gas processing section according to the content of oxious component in the flue gas, generally select three grades, flue gas is through three grades of flue gas processing sections, and harmful substance wherein can be removed substantially fully.
The water supply flusher comprises nozzle and feed pipe, and nozzle is positioned at the top of upper strata screen, and feed pipe is communicated with nozzle in tower body sidewall and tower body inner chamber are run through in the tower body outside.
Structure of the present utility model can further be specially:
Also comprise demister, demister is installed on top layer flue gas processing section top.
Also comprise a plurality of cleaning eyes, cleaning eye is distributed on the sidewall of tower body.
Also comprise observation window, observation window is distributed on the sidewall of tower body.
Like this, treating column passes through cleaning eye after using a period of time, the people can enter in the tower body for the treatment of column and clear up, and with the contaminant removal in the tower body, prevents obstructions such as screen, demister, avoid influencing the treatment effect of flue gas, make the treating column treatment effect can reach best.Observation window on the tower body sidewall then can be used for watching at any time turbulence situation in the tower.
In sum, the utility model has following advantage compared to prior art: domestic waste incineration is burned the purification of the flue gas of generation by treating column, single treatment just can be removed the harmful substance in the flue gas, the gas of handling the back discharging is almost colourless, do not contain hazardous substance, and is better than the discharge standard of GB, and treatment process is simple, equipment is simple, reduced investment, effect is good, is suitable for wide popularization and application.
