Detailed Description
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the invention. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present disclosure. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.
As shown in fig. 1, dust source 17 gets into wet dust collector 4 through draught fan 1, the utility model discloses the vaporific spray set 10 of second has been add in wet dust collector 4, it is located the below of chimney opening, because chimney 6's inside has set up whirl defroster 7, whirl defroster 7's principle is, the spiral upward movement is made to the gas that the whirl board was forced to pass through, gaseous ascending in-process, the droplet liquid stream that the air current smugglied secretly distributes the blade from the blind plate, get rid of to fender liquid board 12 under centrifugal force, the liquid drop receives the action of gravity to flow in ponding groove 14, through annular ponding groove 14, rethread downcomer 15 flows down. The second mist spraying device 10 ensures that dust entering the cyclone demister 7 has certain humidity, and water vapor is fully distributed at the opening of the whole chimney, so that the second mist spraying device is matched with the cyclone demister 7 to better separate the dust.
The dust source may be ammonium sulfate dust.
The utility model discloses in increased the height of fender liquid board 12, the dust that makes blade 13 throw away and liquid drop fully contact on fender liquid board 12, mix then flow down along the bulkhead, set up downcomer 15, the bottom of downcomer 15 stretches into the bottom of wet dust collector 4, can make 15 ends of downcomer below the surface of water to do not receive the air resistance influence during the lower liquid.
The dust is washed by the first mist spray device 9 and then enters the chimney through the second mist spray device 10, and the washed water enters the circulating washing tank 2, so that the dust is effectively dissolved.
Then through whirl defroster 7, through whirl defroster 7 centrifugal action, the dust and the water of throwing away fully contact on the baffle, mix, then flow down along the plate wall.
The residual dust is dedusted by the wire mesh demister 5. The process the utility model discloses an ammonium sulfate dust recovery processing system can realize the emission reduction of dust. The upper side and the lower side of the silk screen demister 5 are supported and fixed, so that the silk screen demister is prevented from falling off.
After the cyclone demister 7 runs for a long time, part of ammonium sulfate blocks can be coagulated, and the cyclone demister spraying device 11 needs to be washed regularly. After the screen mist eliminator 5 runs for a long time, screen blockage is not prevented, and the screen mist eliminator spraying device 8 is required to be regularly washed.
In order to prevent the screen mist eliminator 5 from being blocked, a group of mist spray heads are added at the position 50-70cm away from the upper part of the screen mist eliminator 5 to wash the screen mist eliminator spraying device 8, and the diameter of a circle where the spray heads are located is 1-1.5 m.
The wind speed in the chimney is 4-4.5 m/s.
A second mist spraying device 10 is added in front of the cyclone demister 7, the diameter of a circle where a spray head is located is 0.6-0.8m, and the water mist is ensured to cover the whole chimney opening.
The utility model discloses including a plurality of circulation scrubbing pumps 3, water in the circulation scrubbing tank 2 gets into waste liquid aftertreatment process through circulation scrubbing pump 3 all the way, get into through circulation scrubbing pump 3 all the way and wash silk screen defroster spray set 8, first vaporific spray set 9, the vaporific spray set 10 of second, whirl defroster spray set 11, then fall to wet dust collector 4's bottom, flow back again in the circulation scrubbing tank 2, it utilizes the liquid level difference to provide kinetic energy, the rivers that make the ammonium sulfate dust of having dissolved are to circulation scrubbing tank 2. Get into a certain amount of clear water through the inlet of wet dust collector 4 bottoms at the in-process of circulation, so the circulating water can be used for dissolving the dust again, does not block up the shower nozzle simultaneously, through long-time operation, and the water in the circulation scrubbing groove 2 can be muddy gradually, and the concentration can improve gradually, sprays for not influencing the system, needs the solution in the replacement circulation scrubbing groove, makes it keep certain solubility.
Set up annular whirl defroster spray set 11 in the chimney of emptying, the main effect washs whirl defroster 7 and removes dust further, the reason is whirl defroster 7 after using a period, because ammonium sulfate is easily absorbed moisture, the caking, inevitably accumulate at whirl defroster 7, under the condition of not shutting down, regularly open the shower nozzle, wash each position such as blade, fender liquid board, not only wash the plug, because liquid is sprayed in the air current earlier, the very thin fog that contains in the gas, dust particle size once more condenses into the liquid drop and is separated, the improvement cleanliness.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
