Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0042] Such as figure 1 , The purification device is composed of three parts: L-shaped absorption tower 13, gas channel 14, and horizontal defogging section 15. Among them, the top of the L-shaped absorption tower 13 is provided with a flue gas inlet 1, and the tail of the horizontal demisting section 15 is provided with a flue gas outlet 10 sideways. The pump 4 sends the absorbent in the absorbent pool 5 to the absorbent spraying device 2 arranged below the flue gas inlet 1 for atomization, and the flue gas and the absorbent have a primary contact and reaction. The removing device is externally connected to a motor 12 and a reducer 11, and the motor 12 drives the stirring device 6 and the dispersing and atomizing device 7 to rotate through the reducer 11. Stirring device 6 and dispersing atomizing device 7 are coaxially installed, both are located in...

Abstract

An integrated atmospheric pollutant purifier is disclosed. The bottom of the equipment is externally connected to a circulating pump. By the utilization of the circulating pump, an absorbent is sent to an absorbent spray device arranged below a flue gas inlet, and the absorbent sprayed out of the spray device reacts with pollutants in flue gas. In addition, the purifier also comprises a dispersion atomizing device. The dispersion atomizing device stirs up water sprays to form a water film on an orifice plate, and a turbulent flow vapor-liquid exchange layer is formed. The purifier belongs to a desulphurization, denitration and demercuration integrated device, and has advantages of small floor space, high removal efficiency, low cost of investment and operation, large handling capacity of flue gas and good purification effect. As the inside of the purifier is continuously washed out by circulating slurry, scaling or obstruction will be avoided. With the existence of mixing blades, deposition of the absorbent can be effectively avoided.

Description

technical field [0001] The invention relates to an integrated air pollutant purification device, which belongs to the technical field of air pollutant purification. Background technique [0002] The flue gas or industrial tail gas discharged from various industries such as coal-fired, oil-fired, and gas-fired power plants, metallurgy, chemical industry, and solid waste treatment contains pollutants such as SO2, NOx, and heavy metals (Hg and Ag), which have become increasingly important pollutants in the atmosphere and soil. main source of pollution. With social progress and economic development, the impact of thermal power plants on the atmospheric environment has received widespread attention. Therefore, effectively reducing pollutant emissions to improve the impact on the environment is a severe challenge for the sustainable development of the energy sector in my country and the world. . [0003] At present, there are many treatment technologies for flue gas or industrial...
