Accompanying drawing explanation
The tail gas clean-up supercharging device schematic diagram that Fig. 1 provides for the utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
The tail gas clean-up supercharging device schematic diagram that Fig. 1 provides for the utility model, described tail gas clean-up supercharging device comprises gas inlet 1, high energy atomizer 2, Venturi tube 3, circulating pump 4, vortex shield 5, divide flow container 6, blade demister 7, offgas outlet 8, moisturizing line 9, mend alkali line 10 and sewage discharge line 11, gas inlet 1 is communicated with Venturi tube 3, Venturi tube 3 top connects high energy atomizer 2, Venturi tube 3 bottom is communicated with along point flow container 6 tangential direction with a point flow container 6, the outlet of circulating pump 4 is communicated with high energy atomizer 2, sewage discharge line 11 connects circulating pump 4 and exports, circulating pump 4 import is connected with the outlet at bottom of point flow container 6, with moisturizing line 9 bottom point flow container 6, mend alkali line 10 to be communicated with.Divide flow container 6 top to install blade demister 7, vortex shield 5 is installed in bottom, and offgas outlet 8 is positioned at point flow container 6 top.
Gas inlet 1 is downward-sloping, is 5 ° ~ 20 ° with horizontal direction angle
High energy atomizer 2, Venturi tube 3 are all vertically installed, and the spray angle of high energy atomizer 2 is 15 ° ~ 25 °.
4 vortex shields 5 are installed, the installation of 90 °, adjacent vortex shield interval under dividing flow container 6 liquid level.
Because industrial tail gas is comparatively strong to the corrosivity of equipment, therefore the utility model material adopts 316L.
Utility model works process is as follows: tail gas enters Venturi tube 3 from gas inlet 1, fully mix in Venturi tube 3 with the water smoke sprayed from high energy atomizer 2, gas-liquid mixture is at a high speed by Venturi tube 3, tangentially enter point flow container 6, in Venturi tube 3 in the violent mixed process of gas-liquid, because droplet spouting velocity is higher than gas flow rate, and spray concentration is large, droplet promotes gas flow further downstream, thus to gas boosting about 0.5 ~ 2kPa, enter the gas-liquid mixture of point flow container 6, liquid phase throws to Bian Bi under centrifugal action, flow to point flow container 6 liquid Space, 4 pieces of vortex shields 5 of flow container 6 bottom are divided to alleviate liquid phase eddy current, circulation alkali liquor flows out to circulating pump 4 entrance from point flow container 6 bottom, after circulating pump 4 pressurizes, major part enters high energy atomizer 2, small part is as wastewater disposition, for maintaining pH value and the salt concentration of circulation fluid, need continuous supplementation alkali lye and water, supplementary alkali, supplementing water enter the bottom of point flow container 6.The gas phase entered in the gas-liquid mixture of point flow container 6 is separated water smoke by blade demister 7, discharges through a point flow container outlet 8.
