Description
Technical field
The utility model relates to dedusting technology field, specifically a kind of coal-burning boiler dust arrester.
Background technology
Existing boiler is in order to reduce tail gas pollution, and protection of the environment, installs deduster additional at the offgas outlet of boiler usually.The common dedusting method of boiler is divided into dry method and wet method, and conventional dry method dust generally adopts cloth-sack-type dust removal device, and it is applicable to trap tiny, dry, non-fiber dust.For fiber bag precipitator, often adopt terylene, nylon, polypropylene, tacryl, glass fibre, Fypro etc. as cloth bag material at present, this mode is removed needs for dust stratification on filter bag and is removed thoroughly.If manually beat, productivity ratio is low, labour intensity is high; If mechanical vibrator, filter bag spoilage is high, and replacing and maintenance workload greatly, all do not meet the demand of prior art.And wet dedusting cleaning equipment includes atomizing, cyclone type, column plate type, venturi etc., usually due to sulfur-bearing in flue gas, cleaner after contacting with water, is made easily to corrode.Secondly due to the restriction by various factors, the efficiency of dust collection of single deduster is not very high.Usually to be connected use for improving efficiency of dust collection, or it is reequiped, but often make its floor space or cost of manufacture greatly improve, so both be unfavorable for producing, can not coordinate well to safeguard various cleaner, in actual production, stopping production rate is very high, and practical extending application value is little.
Utility model content
The technical problems to be solved in the utility model is for Problems existing in background technology, provides a kind of coal-burning boiler dust arrester.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of coal-burning boiler dust arrester, comprise dust-removing box, described dust-removing box side is provided with gas approach and exhanst gas outlet, opposite side is provided with water inlet, described exhanst gas outlet is arranged at below gas approach, described gas approach is connected with boiler by pipeline, smoke guide wall is provided with above the junction of described dust-removing box inwall and gas approach, spray equipment is provided with in dust-removing box below described smoke guide wall, described spray equipment comprises multiple atomizer and spray header, described atomizer is evenly arranged on described spray header, described spray header is connected with external pipe by water inlet, on dust-removing box inwall below described spray equipment, relative dust-removing box is provided with oblique baffle plate obliquely, dust-exhausting port is provided with bottom described dust-removing box.
Further, described oblique baffle plate is arranged on the dust-removing box inwall in region between described gas approach and exhanst gas outlet.
Further, the shape of described smoke guide wall is set to arc.
Adopt a kind of coal-burning boiler dust arrester of the present utility model; owing to arranging smoke guide wall above gas approach; dust-removing box inwall simultaneously below spray equipment is provided with oblique baffle plate, thus shower water and flue dust can be made fully to contact the object reaching dedusting, its energy consumption is low; working stability; maintenance load is little, and overall structure is simple, easy to use; meet the demand in market, be conducive to environmental protection.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Shown in figure: 1-dust-removing box, 2-gas approach, 3-exhanst gas outlet, 4-water inlet, 5-smoke guide wall, 6-atomizer, 7-spray header, the oblique baffle plate of 8-, 9-dust-exhausting port.
Detailed description of the invention
As shown in Figure 1, a kind of coal-burning boiler dust arrester of the present utility model, comprise dust-removing box 1, described dust-removing box 1 side is provided with gas approach 2 and exhanst gas outlet 3, opposite side is provided with water inlet 4, described exhanst gas outlet 3 is arranged at below gas approach 2, described gas approach 2 is connected with boiler by pipeline, smoke guide wall 5 is provided with above the junction of described dust-removing box 1 inwall and gas approach 2, spray equipment is provided with in dust-removing box 1 below described smoke guide wall 5, described spray equipment comprises multiple atomizer 6 and spray header 7, described atomizer 6 is evenly arranged on described spray header 7, described spray header 7 is connected with external pipe by water inlet 4, on dust-removing box 1 inwall below described spray equipment, relative dust-removing box 1 is provided with oblique baffle plate 8 obliquely, dust-exhausting port 9 is provided with bottom described dust-removing box 1.
Further, described oblique baffle plate 8 is arranged on dust-removing box 1 inwall in region between described gas approach 2 and exhanst gas outlet 3, can increase shower water and flue dust time of contact like this, also can reduce the corrosiveness of water in dust removal to dust-removing box 1 inwall simultaneously.
Further, the shape of described smoke guide wall 5 is set to arc, effectively can reduce the percussion of flue gas to dust-removing box like this, also can reduce the impact of flue gas on spray equipment simultaneously.
In actual use, when boiler smoke enters in dust-removing box 1 by gas approach 2, then open spray equipment and can carry out dust removal process, dust-laden waste water in spray process enters in the sedimentation basin of outer setting by dust-exhausting port 9, and the flue gas after dedusting enters into next treatment process by dust-removing box 1 upper smoke outlet 3.And the waste water in sedimentation basin can be recycled by water pump after precipitation.
Adopt a kind of coal-burning boiler dust arrester of the present utility model, owing to arranging smoke guide wall 5 above gas approach 2, dust-removing box 1 inwall simultaneously below spray equipment is provided with oblique baffle plate 8, thus shower water and flue dust can be made fully to contact the object reaching dedusting.Its energy consumption is low, working stability, and maintenance load is little, and overall structure is simple, easy to use, meets the demand in market, is conducive to environmental protection.
Protection domain of the present utility model is not limited only to the technical scheme disclosed in detailed description of the invention; the foregoing is only better embodiment of the present utility model; do not limit the utility model; every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
