Technical field
The utility model relates to and is used for industry, station boiler, the desulfurization integrated environmental protection equipment of kiln coal-fired flue-gas high-effective dust-removing, particularly a kind of high-efficiency desulfurization device of being made by granite.
Background technology
At present, existing many coal-fired flue-gas dust-removing and desulfurization integration apparatus, quite ripe technically, but all have aspect problems not fully up to expectations such as equipment service life, dust-removal and desulfurizing efficient, equipment price.
Summary of the invention
The purpose of this utility model is to provide that a kind of employing granite is made, water distribution is even, corrosion-resistant, wear-resistant, can have the high-effective dust-removing desulfurization performance by assurance device, can solve the high-efficiency desulfurization device of the random turbulence motion problems of flue gas again.
Above-mentioned purpose of the present utility model is to realize by following technical scheme: the high-efficiency desulfurization device, comprise: tower body, water-locator, cleaning solution feed tube, be positioned at demister on the feed tube, advance mouth, the delivery port of outlet flue, manhole door and tower body bottom, it is characterized in that: the below of the cleaning solution feed tube in the tower body vertically is equipped with corrosion resistant current stabilization post, the top radial equipartition of current stabilization post has first order swirl vane, water-locator is positioned under the swirl vane, and its water distribution sheet radial equipartition and upstream face tilt to current stabilization post direction; Swirl vane group and water-locator constitute cyclone, and 1～10 grade of cyclone is installed in the tower body at least.
The utility model is because said structure and the dust-removal and desulfurizing effect is remarkable: efficiency of dust collection can reach 94%～99%, can match in excellence or beauty with three electric field electric cleaners, and stability, good reliability.Desulfuration efficiency: when raw coal sulfur content 〉=3.5%, when pH value is 7, the desulfuration efficiency of equipment can reach 50%～70%; PH value is 8～14 o'clock, and the desulfurization friendship rate of equipment can reach 60%～98%, and in addition, the utility model can efficiently be removed atmosphere pollution materials such as flue dust in boiler, the kiln coal-fired flue-gas, sulfur dioxide, nitrogen oxide.Particularly the employing of granite material makes equipment have fabulous decay resistance and anti-wear performance, manufacturing cost is the reduction at the end significantly, and simple in structure, floor space is little, reduced investment, operating cost is low, maintenance management is convenient, do not need the professional to move.Handle boiler, kiln coal-fired flue-gas with this equipment, can reach the existing discharge standard of national environmental protection department to the removal effect of dust in flue gas and molecularity polluter.The utility model is equally applicable to the purified treatment of other kind pernicious gas.

The specific embodiment
, be further described the utility model below in conjunction with description of drawings.
Referring to accompanying drawing: comprise among the figure: tower body 1, water-locator 3, cleaning solution feed tube 5, be positioned at demister 6 on the feed tube, advance the delivery port 10 of mouth 9, outlet flue 7, manhole door 8 and tower body 1 bottom; Wherein the below of the washing lotion feed tube 5 in the tower body 1 is equipped with the current stabilization post 2 of anti-mansion erosion, the top radial equipartition of current stabilization post 2 has swirl vane 4, water-locator 3 is positioned under the swirl vane 4, its water distribution sheet radial equipartition also tilts to current stabilization post 2 directions, swirl vane group and water-locator 3 constitute cyclone, in the present embodiment, 1 grade of cyclone is installed in the tower body; In addition, in the present embodiment, described tower body 1, water-locator 3, swirl vane 4, the delivery port 10 that enters mouth 9, outlet flue 7, manhole door 8 and tower body bottom all adopt granite to make. wherein, water-locator 3 is the granite overall structure with tower body 1, its upstream face 11 is 5 °～85 ° inclinations to current stabilization post 2 directions. and the upstream face of swirl vane 4 is 0 °～30 ° inclinations to the horizontal center of tower body 1. and cleaning solution feed tube 5 can adopt stainless steel tube, and demister 6 adopts granite or stainless steel to make.
Operation principle of the present utility model is such: boiler, the coal-fired flue-gas of kiln tangentially enters in the tower from the mouth 9 that advances of tower bottom, around current stabilization post 2, form the flue gas of left-handed or dextrorotation, flow spiral rises and passes water-locator 3, swirl vane 4, the washing absorption liquid is entered in the tower by water inlet pipe, by current stabilization post 2 tops to around evenly scatter, on blade, form some moisture films, the washing absorption liquid that flows down from blade is distributed on the next stage blade by the collection of the upstream face of water-locator, be formed uniformly some moisture films, when the exhaust gases passes blade, flue dust, sulfur dioxide, nitrogen oxide obtains washing and depositing, when the flue gas of band water smoke passes through demister, can successfully carry out gas-water separation, clean flue gas is through outlet flue 7, air-introduced machine, smoke stack emission, dust-laden, H2SO3, H2SO4 acid waste water overflows through the delivery port water seal of tower bottom, through the gutter, regulating reservoir, gray water separation equipment or ash settling basin are after adding alkali and regulating pH value, pass through water circulating pump again, realize the closed cycle of water.Ash then passes through the deliming dehydration equipment or manually pulls out to dry remaking comprehensive utilization.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solutions of the utility model content,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present utility model.
