Abstract
The utility model relates to a multi-stage splash wet desulfurizing and dust-removing device which is a dust-removing device. The middle part of a barrel body of the dust-removing device is provided with a plurality of groups of partition boards and water splashing boards in the staggered arrangement from bottom to top, the center of each water splashing board is provided with a water nozzle, the upmost water nozzle is a clear water nozzle, other nozzle below the clear water nozzle are alkaline water nozzles, the partition boards, the water splashing boards and the water nozzles in the staggered arrangement form multi-stage serial-connection splash, the lower part of the barrel body is provided with a gas inlet pipe downwards bending 90DEG, and the upper part of the barrel body is provided with a gas-water separator with double inlets. When dusty gas flows through the dust-removing device, the dusty gas passes through the water nozzles for many times to form water film, water froth, water splash and water curtain, gas and water have large contact area, long contacting time and far contacting range, and the utility model has good desulfurizing and dust-removing effect.
Description
The utility model relates to a kind of deduster, particularly relates to a kind of multistage splash wet type desulfurizing dust collector.
The wet scrubber that uses has impact type wet scrubber and water film type wet dust removal two big classes at present.The operation principle of impacting wet scrubber is: dusty gas impacts the water surface that floods air inlet mouth of pipe degree of depth 10-30 millimeter with the fair speed of 8-10 meter per second, form the foam and the spray of fierce disturbance, gas, water two are contacted, under the adhesive force effect of inertia force and water, grit is left in the water, reaches the dedusting purpose.The operation principle of water film type wet scrubber is: the high speed of dusty gas about with 20 meter per seconds tangentially enters the cylindrical shell of deduster, produce strong rotation, grit gets rid of to barrel under action of centrifugal force, by moistening along the moisture film of wall overflow, and, reach the purpose of dedusting with water inflow ash discharge water pipe.The shortcoming of above-mentioned two kinds of wet scrubbers is: the contact area of dusty gas and foam, spray, moisture film is little, the time short, stroke is near, dust removing effects is subjected to a certain degree influencing, and gas falls greatly at deduster medium velocity height, pressure, energy loss is big.
The purpose of this utility model is to provide a kind of dusty gas and foam, spray, the moisture film contact area is big, the time long, stroke is far away, dust removing effects is better and the multistage splash wet type desulfurizing dust collector of desulfurizing function is arranged.
The multistage splash wet type desulfurizing dust collector of the utility model primary structure comprises: cylindrical shell, be arranged on the gas inlet tube on the cylindrical shell lower sides, this gas inlet tube is bent downwardly 90 °, allow nose end face down, be arranged on cylindrical shell ashpit bottom, ash discharging hole on the ashpit sidewall and water seal plate washer, be provided with the dividing plate of staggered garden dish type from bottom to top at cylindrical shell middle part and the splash board of garden ring-type is organized more, topmost the center of a splash board is provided with water nozzle, below the center of each piece splash board be provided with alkaline recirculated water nozzle, every dividing plate is together with its adjacent splash board in top, (operating) water nozzle constitutes one-level splash combination together, just form plural serial stage splash combination from bottom to top, be arranged on the double feed inlet moisture trap on cylindrical shell top and the gas outlet tube at top in addition.The remarkable difference of this desulfurizing dust-collector and existing wet scrubber is: it only is to allow mouth of pipe end face towards the water surface of ashpit that gas inlet tube is bent downwardly 90 °, and mouth of pipe end face is not to be flooded by the water surface; Cylindrical shell middle part from bottom to top since be dividing plate, splash board, (operating) water nozzle, dividing plate ... the staggered repetition of (operating) water nozzle arranged, forms the plural serial stage splash of water; Independently double feed inlet moisture trap is arranged at deduster top.
The course of work of the multistage splash wet type desulfurizing dust collector of the utility model is: dusty gas enters deduster from gas inlet tube, effect by 90 ° of elbows of gas inlet tube, dusty gas changes the flow direction, rush at the water surface of ashpit downwards, the coarse granule grit is by means of self inertia power and gravity, directly pour in the ashpit water and be removed, the distance between the terminal mouth of pipe of gas inlet tube and the ashpit water surface is by the height adjusting of water seal plate washer.Gas upwards flows after entering cylindrical shell, pass moisture film, foam, spray, cascade that multistage alkaline recirculated water and the splash of one-level clear water form from bottom to top successively, gas, water two-phase are fully contacted, and grit is left in the water under the effect of water adhesive force, simultaneously the SO in the gas
2Also be left in the water Deng acidic materials and alkaline recirculated water generation neutralization reaction, fall step by step under the effect of gravity with splash water, fall in the water of ashpit, grey aqueous mixtures is finally discharged deduster through ash discharging hole, water seal plate washer.The double feed inlet moisture trap dehydration that clean gas behind the desulfurization and dedusting further rises and enters cylindrical shell top, make it dry, leave deduster from gas outlet tube at last, clear water and alkaline recirculated water respectively from water nozzle and alkaline recirculated water nozzle with the garden dish type, the film shape, level sprays into cylindrical shell, straight spray garden ring-type splash board wall, each grade splash is made up, film shape water from the nozzle ejection, directly contact with uprising gas on the one hand, hit on the other hand on the ring-type splash board wall of garden, form foam, water droplet has further increased the contact area with uprising gas again, these moisture films, water droplet is dropping downwards under the gravity effect on the dish type dividing plate of garden, drop once more from the dividing plate edge and to enter next stage splash combination, the cascade that forms that drops for twice contacts with uprising gas equally, as seen gas whenever passes one-level splash combination and just can repeatedly contact with water, and desulfurization and dedusting is highly advantageous to.
The advantage of the multistage splash wet type desulfurizing dust collector of the utility model is, after dusty gas is gone into deduster, at first utilize the gravity and the inertia force of grit to remove the bulky grain grit, and then repeatedly contact with the moisture film, foam, spray, the cascade that fall to forming with water projection, make the probability height that gas, water two-phase contact area are big, the time long, stroke is far away, the dusty gas grit is caught by water, SO in the gas
2Thorough Deng acidic materials and alkaline recirculated water generation neutralization reaction, so desulfurization and dedusting is effective, before gas flowed out deduster, through ad hoc double feed inlet moisture trap dehydration, so the moisture that gas is taken out of was few, is specially adapted to contain floating dust and SO
2More dedusting desulfurization.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
