Description of the drawings:
FIG. 1 is a schematic view of the overall structure of the present invention;
in the figure: 1. a smoke inlet; 2. a first spray tower; 3. a first dust removal duct; 4. a second spray tower; 5. a second dust removal duct; 6. a third spray tower; 7. a third dust removal duct; 8. a water tank; 9. an activated carbon adsorption tank; 10. a fourth dust removal pipe; 11. a smoke outlet; 12. a first spraying device; 13. a second spraying device; 14. and a third spraying device.
The specific implementation mode is as follows:
the present invention will be explained in more detail by the following examples, which are intended to disclose all changes and modifications within the scope of the present invention, and the present invention is not limited to the following examples;
the device for drying, dedusting and deodorizing tungsten concentrate comprises a first spray tower 2, a smoke inlet 1 is formed in the side portion of the first spray tower 2, the top of the first spray tower 2 is connected with the side face of a second spray tower 4 through a first dedusting pipeline 3 in a sealing mode, the top of the second spray tower 4 is connected with the side face of a third spray tower 6 through a second dedusting pipeline 5 in a sealing mode, a third dedusting pipeline 7 is arranged at the top of the third spray tower 6, the third dedusting pipeline 7 is inserted into the bottom of a closed water tank 8, the upper end of the water tank 8 is connected with a fourth dedusting pipeline 10 in a sealing mode, the fourth dedusting pipeline 10 is connected with the lower portion of the side face of an active carbon adsorption tank 9 in a sealing mode, a smoke outlet 11 is formed in the top of the active carbon adsorption tank 9, and spray devices are arranged on the first spray tower 2, the second spray tower 4 and the third spray tower 6 and used for purifying dust and harmful smoke.
The spraying device comprises a spraying pump, the spraying pump is connected with the spray heads inside the spraying towers through pipelines, and the position of the spray head inside each spraying tower is higher than the position of the smoke inlet on the corresponding spraying tower. As shown in the figure, flue gas and dust move from bottom to top in the spray tower, so need set up the position of shower nozzle in the top of advancing the cigarette mouth, the shower nozzle adopts the fire control shower nozzle, can guarantee the water yield, does not let out water atomization, and along with the pipeline gets into next process, can make spun water disperse as far as possible again, reduces dust concentration.
Water is arranged in the first spray tower 2 and the second spray tower 4, and the water level is lower than the height of the position of the smoke inlet of the corresponding spray tower; an alkaline solution is arranged in the third spray tower 6, and the liquid level is lower than the height of the position of the upper smoke inlet in the third spray tower. The first spray tower 2 and the second spray tower 4 mainly filter dust in the tail gas, and reduce the dust concentration in the tail gas through spraying water, and the third spray tower 6 mainly removes harmful gas with peculiar smell in the tail gas through the neutralization reaction of an alkaline solution, such as a sodium hydroxide solution, and an acidic substance, such as sulfur dioxide, in the tail gas.
And liquid discharge valves are arranged at the bottoms of the first spray tower 2, the second spray tower 4 and the third spray tower 6. The primary purpose of the first spray tower 2 and the second spray tower 4 is to remove dust, so after a period of time, the spray water in the towers becomes dirty due to the mixing of much dust, so that the spray water needs to be discharged through a liquid discharge valve, and after the discharge is finished, new clean water is injected again. And the drain valve on the third spray tower 6 is also used for discharging the solution in the tower, and after a long-time neutralization reaction, the pH of the solution in the tower is gradually reduced and even becomes acidic, so that the acidic substances in the tail gas cannot be neutralized and absorbed, and the solution needs to be discharged and replaced.
The heights of the second spray tower 4, the first spray tower 2 and the third spray tower 6 are sequentially increased progressively. In order to save resources and accelerate purification, dust in the tail gas is not much after dust removal is carried out by the first spray tower 2, so that the second spray tower 4 can be relatively small, spray water can be combined with a small amount of acidic substances in the tail gas in the dust removal process, so that only one spray tower is adopted for tail gas neutralization after dust removal, and the spray tower is larger than the spray tower for dust removal in order to enable the reaction to be thorough.
The water tank 8 is a closed water tank, and a liquid discharge valve is arranged at the bottom of the water tank 8. The water tank 8 is positioned at the end of the working procedure, dust and acidic substances in the flue gas can be filtered again, the full filtration is ensured, and a drain valve at the bottom of the water tank 8 is also used for replacing the water in the water tank regularly.
The activated carbon adsorption box 9 is used as a tail end purification device, and can adsorb dust and peculiar smell harmful gas which are omitted in the preamble, so that the discharged tail gas is ensured not to be polluted, and a good working environment is provided for workers.
The details of the above are not described in detail since they are prior art.
