Description
Technical field
The utility model relates to a kind of wet-scrubbing equipment.
Background technology
Wet scrubber is used for grit is transferred to one other fluid from air-flow, and this transfer process depends primarily on three factors, the size of contact-making surface area between gas and the fluid; Relative motion between these two kinds of fluid states of gas and liquid; Relative motion between dust granules and the fluid.
Water dust scrubber is that a kind of the utilization used the moisture film that causes someway on dusty gas impact dust remover inwall or other special components, dust is caught, the cleaning equipment that gas is purified by moisture film.Its operation principle is: dusty gas is introduced along tangential by the cylindrical shell bottom, and rotation is risen, and grit is subjected to centrifugal action and separated, throws to cylinder inboard wall, and the water film that is flowed by the cylindrical shell inwall adsorbs, and flows to the bottom cone with water, draws off through dust-exhausting port.The formation of water film is with the suitable wall that tangentially is sprayed onto of water by the several nozzles that are arranged in cylindrical shell top.Like this, cover all the time the very thin water film that one deck rotation flows downward at cylinder inboard wall, reach the purpose that improves dust removing effects.
What China the most generally used since the seventies in last century is gallet water curtain dust collector, and this wet scrubber structure is often fairly simple, and the cylindrical shell of its hollow is to build by laying bricks or stones with natural granite to form, therefore acidproof, anticorrosion, wear-resisting, long service life, metal consumption is little, and water consumption is little; Its shortcoming is highly large (often about 10m), difficult arrangement, and in actual motion, find to have water phenomenon.
Summary of the invention
Goal of the invention of the present utility model is to overcome the existing problem that gallet water curtain dust collector gas-liquid contact face is less, device height is larger and provides that a kind of cylindrical shell height is lower, the water dust scrubber of good dedusting effect.
The technical solution of the utility model is: the cylindrical shell top is provided with spray thrower; The cylindrical shell middle part is provided with bracing frame; Be filled with filler in the cylindrical shell of support frame as described above top, spray thrower bottom; The cylindrical shell bottom is provided with air intake vent; Air intake vent links to each other with the air-introduced machine of carrying dusty gas through pipeline; Cylinder body bottom links to each other with tank through pipeline; The air intake vent horizontal level is to have overfall on the cylindrical shell; Overfall links to each other with tank through pipeline.
Described cylindrical shell is funnel-shaped structure.
Described cylinder body bottom is provided with the cone bucket; Described cone bucket links to each other with tank through pipeline.Recirculated water in the described tank can be prepared according to technological requirement, makes it have the effects such as dedusting, recovery, neutralisation treatment.
Described tank links to each other with spray thrower with pipeline through water circulating pump.
Described air intake vent and cylindrical shell barrel are tangential setting so that the dusty gas spiral that air-introduced machine is sent here rises.
Described overfall is tangential setting and consistent with the swirling eddy direction of air intake vent formation with the cylindrical shell barrel, with anti-gas-leak.
Described cylindrical shell height is 1-5m; The whole height of the filler of filling in the described cylindrical shell is greater than 30cm; The single diameter of described filler is 3-10cm.
Described filler is cobblestone or corrosion resistant stone material, and the single profile of described corrosion resistant stone material is the large as far as possible profiles of single surface area such as rule or irregular spheroidal, ellipse, multiaspect rhombus.
Described spray thrower comprises a circular pipe and is arranged at an above straight tube that is connected with ring tube in the annulus; The periphery of described circular pipe is provided with tangential small-hole so that cylinder inboard wall forms the direction of rotation uniform water film opposite with the tangential approach axis of gas; On the described straight tube staggered be provided be 30-60 ° of downward aperture with vertical direction so that shower water at filling surface cloth film.
The material of described cylindrical shell is ordinary carbon steel plastic lining or corrosion resistant stainless steel.
Pile up in the cylindrical shell of the present utility model the natural of certain altitude or non-natural filler (corrosion resistant stone material, cobblestone) are arranged, arrange spray thrower on stone layer top, make stone layer and cylinder inboard wall can both form uniform water film, dusty gas increases greatly with capture moisture film contact area, satisfying in the stream pressure situation, diameter and the piling height of stone material have determined dust removing effects.The cylindrical shell height then reduces (according to gas dust content size, cylindrical shell height 1-5m) greatly, needs corresponding increase cross-sectional area when highly reducing, not increase resistance as purpose.Cylinder material can the ordinary carbon steel plastic lining or the corrosion resistant stainless steel replace numb stone granite, equipment self-weight greatly alleviates.
1), the cobblestone cost is low and corrosion-resistant the beneficial effects of the utility model:; 2), simple in structure, fabrication and installation are convenient; 3), increase the gas-liquid contact area, better than hollow cylinder dust removing effects; 4), SR is less; 5), tail gas is by the direct qualified discharge of stone layer height and Auto-regulating System of Density of Heavy Medium, non-secondary pollution.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model spray thrower.
Among the figure, 1, cylindrical shell, 2, cobblestone, 3, spray thrower, 4, bracing frame, 5, tangential inlet, 6, air-introduced machine, 7, the cone bucket, 8, tank, 9, water circulating pump, 10, overfall.
The specific embodiment
Among Fig. 1, place the bracing frame 4 that supports cobblestone 2 on the tapering, cylindrical shell 1 bottom, bracing frame 4 can be through antiseptic ordinary carbon steel or other corrosion resistant materials, but have on enough strength support stone layers and the bracing frame 4 enough holes or gap are arranged, assurance from the recirculated water of spray thrower 3 ejection through stone layer and cylinder inboard wall to downstream to cone bucket 7, tangential inlet 5 usefulness on cone bucket 7 tops are so that the dusty gas spiral rising that air-introduced machine 6 is sent here.The dust-containing water that flows out enters tank 8 to be continued to recycle through squeezing into spray thrower 3 by water circulating pump 9 after suitably processing.Unlikely too high for the dust-containing water water level in the control cone bucket 7, overfall 10 is set below the horizontal level of tangential inlet 5 leads to tank 8.
Fig. 2 is the top view of spray thrower 3, be drilled with tangential small-hole so that cylinder inboard wall forms the direction of rotation uniform water film opposite with the tangential approach axis of gas in the pipe periphery, the straight tube of centre staggered be drilled with downward 30-60 ° aperture usefulness so that shower water at cobblestone 2 surperficial cloth films.
The utility model can be used in the exhaust gas recovery system (final stage recovery) of drying equipment such as spray drying tower, and effect is better than other dry dust removal methods.Spray tower tail gas has solved the problem of wet scrubber recirculated water low temperature in winter easy freezing generally more than 80 ℃.Spray tower tail gas is mingled with some trickle powders and enters the utility model, contact, mix by the moisture film of cylindrical shell tangential inlet with cylinder inboard wall and the interior filling surface of piling up of cylinder, trickle powder enters circulating water chennel with the cone bucket outlet that moisture film flows downward to the cylindrical shell bottom, recirculated water returns again the top spray thrower, the gas qualified discharge of separating after precipitation, filtration or other processing.Recirculated water can be prepared according to technological requirement, makes it have the effects such as dedusting, recovery, neutralisation treatment.
