The dust removing liquid is generally washing liquid, wherein the washing liquid is selected according to the dust to be removed, and the liquid which is easy to adsorb the dust to be removed is selected.
The working process of the wet dedusting system is as follows:
after the dedusting task of the dedusting liquid in the wet dust collector 10 is completed, the dedusting liquid is changed into dedusting liquid mixed with impurities, the dedusting liquid is discharged from a dedusting liquid outlet 12, enters the filter press 100 from a filter press feed inlet 101, is filtered by the filter press 100 to obtain clear dedusting liquid after being filtered, the filtered dedusting liquid flows out from a filter press liquid outlet 103 to achieve the purpose of separating the dedusting liquid, and the separated dedusting liquid enters the wet dust collector 10 through a dedusting liquid inlet 11 for recycling;
the waste slag generated after filtration is discharged from the filter press slag outlet 102 and enters the dryer 200 from the dryer slag inlet 2011;
at this time, hot water is continuously introduced into the jacket 202 through the hot water inlet 2025 and is discharged through the hot water outlet 2026, and the jacket 202 is wrapped on the outer surface of the shell 201, so that the jacket 202 can transfer heat to the shell 201 to heat the waste residues in the shell 201;
since the filter press 100 cannot sufficiently dry the waste residue, a large amount of dust removing liquid remains on the waste residue. Therefore, when the waste residue is heated, the dedusting liquid remained in the waste residue is evaporated, becomes gas after evaporation, moves upwards and is discharged along the steam outlet 2013, so that the aim of separating the dedusting liquid is fulfilled;
the separated steam is the gas-state dedusting liquid, the steam enters the steam condenser 300 from the steam inlet 301, the steam is condensed by the steam condenser 300 to obtain liquid dedusting liquid, and the liquid dedusting liquid enters the wet dust collector 10 through the dedusting liquid inlet 11 for recycling;
the above process continues until the dust removal task is completed, and the heating of water into the jacket 202 is stopped;
the dryer tap hole 2012 is opened to discharge the slag.
Wherein the hot water introduced into the jacket 202 may be hot water produced in other sections of the plant, and is directed to be used therein to save energy.
Further, the hot water introduced into the jacket 202 needs to reach a predetermined temperature, and if the hot water cannot reach the predetermined temperature, the hot water needs to be heated and then introduced into the jacket 202. The preset temperature is generally 70-80 ℃, if the temperature is lower than 70 ℃, the drained hot water needs to be heated, and the hot water can be introduced into the jacket 202 for use after reaching the preset temperature.
As can be seen from the above, the wet dedusting system provided in the embodiment of the present application includes not only the filter cloth filter press, but also the dryer, so that after the filter cloth filter press filters the dedusting liquid, the filtered waste residue enters the dryer again, the waste residue is heated by hot water, so that the waste residue is the residual dedusting liquid, is heated to become steam, and is then discharged from the steam outlet, and after being discharged, the waste residue is condensed by the steam condenser, so that the dedusting liquid after further separation can be obtained; compare in prior art only through filter cloth pressure filter separation dust removal liquid, the dust removal liquid in the filter residue is further separated through the desiccator to this application embodiment to improve the rate of recovery of dust removal liquid, and then reduced the dust removal cost.
In addition, when the vapor is condensed by the vapor condenser 300, the dust removing liquid can be conveniently recovered, and after the vapor is condensed, the vapor in the vapor condenser 300 is reduced, the pressure is reduced, the vapor can be accelerated to be discharged from the drying machine 200, and the air pressure in the drying machine 200 is reduced, so that the evaporation speed of the dust removing liquid remaining in the waste residue is accelerated, and the recovery efficiency is improved.
In addition, in the above dust removing process, after the dust removing task is completed, the dust removing liquid is still discharged from the wet dust removing device 10, so that the dust removing liquid discharged last can be separated and recovered by using the filter cloth filter press 100, the dryer 200, the jacket 202 and the steam condenser 300, and then is filled into another container for further use.
When the waste residues are dried to a certain degree during dust removal by separation and recovery, the separation of the dust removal liquid is determined to be completed, wherein the drying time of the waste residues can be determined when the waste residues are dried to a certain degree, and the humidity of the waste residues discharged from the slag outlet 2012 can also be determined. In addition, other processes of separation similar to the above processes are not described herein.
