Abstract
The utility model relates to a smoke treatment device for a rotary kiln, which comprises a rotary kiln, a sedimentation chamber, a horizontal cyclone water-film dust remover, a dewatering device, a draught fan and a chimney, wherein the devices are successively arranged according to a smoke flow direction and are communicated with each other through pipelines. The utility model is characterized in that a dry cyclone dust remover is added in front of the horizontal cyclone water-film dust remover. The utility model uses the method that the dry cyclone dust remover is added on the front end of a wet horizontal cyclone water-film purifier; in this way, the dust quantity which enters the wet dust removing system is low so that the dust can not be largely deposited in a circulating water groove and a water groove of the dewatering device, and meanwhile, sludge discharging pipelines are also added on the water groove of the dewatering device and the circulating water groove and are used for periodically discharging the sludge. The smoke treatment device of a rotary kiln of the utility model can cause a rotary kiln to carry out production under the stable condition, does not need to switch the system, ensures the system to continuously operate, and meanwhile, prevents the dust and the harmful gas from discharging to the atmosphere so as to realize the function of environmental protection.
Description
Technical field
The utility model includes the fume treatment auxiliary in the non-ferrous metal refining process, particularly relates to a kind of rotary kiln flue gas processing device.
Background technology
In the prior art, the horizontal cyclone moisture film clarifier of wet method is normally adopted in the smoke gas treatment of rotary kiln, promptly flue gas that comes out from rotary kiln and dust are after the expansion chamber sedimentation, directly enter the dedusting of horizontal cyclone moisture film clarifier, through the dehydrator dehydration, finally discharge (as shown in Figure 1) then from chimney.Because the content of dust is very big in the flue gas; to such an extent as to a large amount of dust settlings is in the circulating water chennel and dehydrator tank of horizontal cyclone moisture film clarifier; make the producer have in running, shut down cleaning mud; and this cleaning cycle is also short especially; generally have only 3～4 days; cause system to move continuously, what influence was produced normally carries out.
Summary of the invention
The objective of the invention is to overcome the defective of above-mentioned prior art, provide a kind of and both can guarantee that system moved continuously, can stop discharging dust and pernicious gas in atmosphere again, realize the rotary kiln flue gas processing device of environmental protection.
The purpose of this utility model is achieved through the following technical solutions:
A kind of rotary kiln flue gas processing device, comprise rotary kiln, expansion chamber, horizontal water-film syclonet, dewater unit, air-introduced machine and chimney, the said equipment sets gradually according to flue gas flow direction and is interconnected by pipeline, it is characterized in that: add the dry type cyclone dust collectors in the place ahead of above-mentioned horizontal water-film syclonet;
The mud discharging pipe is installed on the circulating water pool of above-mentioned horizontal water-film syclonet and the dewater unit.
The utility model installs the cyclone dust collectors dedusting of a dry type additional at the horizontal cyclone moisture film clarifier front end of wet method, the Dust Capacity that enters wet method dedusting system so just seldom, can bulk deposition in circulating water chennel and dehydrator tank, simultaneously, the utility model also installs the pipeline of blowdown mud additional at circulating water chennel and dehydrator tank, be used for regularly discharging mud.Rotary kiln flue gas processing device of the present utility model can make rotary kiln produce under stable condition, does not need system to switch, and has guaranteed the continuous operation of system, also stops discharging dust and pernicious gas in atmosphere simultaneously, realizes environment-friendly function.
Description of drawings
Fig. 1 is the structural representation sketch of smoke gas treatment device of the prior art;
Fig. 2 is the structural representation sketch of the utility model rotary kiln flue gas processing device.
The specific embodiment
Rotary kiln flue gas processing device of the present utility model, comprise rotary kiln 1, expansion chamber 2, horizontal water-film syclonet 3, dewater unit 4, air-introduced machine 5 and chimney 6, the said equipment is interconnected according to the flue gas flow direction setting and by pipeline 7, add dry type cyclone dust collectors 8 in the place ahead of above-mentioned horizontal water-film syclonet 3, simultaneously on the circulating water pool 10 of horizontal water-film syclonet 3 and dewater unit 4, mud discharging pipe 9 is installed.During production, after flue gas and dust come out from rotary kiln 1, after at first passing through expansion chamber 2 sedimentations, be admitted to dry type cyclone dust collectors 8 and carry out dedusting first, and then be admitted to horizontal water-film syclonet 3 and carry out wet dedusting, the dehydration back is sent into chimney 6 by air-introduced machine 5 and is discharged, and this method can be removed a large amount of dust before entering wet dust removal, thereby reduce the dust pile cumuliformis condition of subsequent process, thereby the assurance system moves continuously.
