Description
It is a kind of to flue dust dust and SO 2 from fume and other pernicious gas tools spray cyclone tower with the double purified effect that the utility model belongs to.(desulfurizing dust-collector)
At present, known desulfurizing dust-collector has the crack impact type, inside and outside two cyclone type is arranged, spraying auto-excitation type and pure rotating stream tray scrubber formula etc. is arranged.Have plenty of metal material and add coating; Have plenty of stainless steel part, all can not be corrosion-resistant for a long time; Though what have is made by corrosion resistant granite or pottery, general resistance height, gross efficiency is low or desulfuration efficiency is low.Especially ubiquitous defective is that gas-water separation is bad, and the outlet flue gas with water influences the life-span of pipeline and air-introduced machine thereafter, increases maintenance capacity and operational and administrative expenses.
The utility model is the patent inventor after analyzing, studying various desulfurizing dust-collectors, the own former patent No. be 86210154.9 and application number be on the 92217191.2 utility model desulfurizing dust-collector patent bases, through improving the regeneration product of raising.
The purpose of this utility model provides a kind of spray cyclone tower.The principle that integrates spraying, whirlwind, eddy flow, make its innovation simple and reasonable for structure, occupation of land is little, resistance is low, less energy consumption, the outlet flue gas is not with water, to flue dust, dust and sulfur dioxide and other cleaning harmful gas efficient height, full granite is made, long service life, the desulfurization and dedusting spray cyclone tower that operating cost is low.
The purpose of this utility model is achieved in that the granite process processing with anticorrosive anti-wear, builds conglobate tower body shell and core body by laying bricks or stones.In the circumferential weld between tower body and core body, two-layer granite spinning disk and one deck demist sheet through correct grinding is installed.Lift angle α=25 of spinning disk °～30 °, efficiency factor F
0=8～9.Demist sheet lift angle α=25
0=8.Tangential direction is consistent rotates by entering the mouth.Below the ground floor spinning disk, be on the tangential direction of granite tower body bottom, have the rectangle entrance seat, its width is equal to or less than the circumferential weld width between tower body and the core body, its width is during greater than 400 millimeters, and the center installs a granite abrasive disc dividing plate contour with inlet additional.Go into tower with 13～15 meter per second tangent lines, the seat bilateral symmetry that entered the mouth is installed 2～12 spraying humidifications of 55～60 degree angle nozzles.When flue gas enters ground floor second layer spinning disk, be installed in the nozzle spraying humidification on the tower body shell.Small particle (dirt) is through turbulent flow, and cohesion is captured down.Pernicious gases such as sulfur dioxide, through absorption, absorb, neutralization reaction etc. and removing.Nozzle is the straight nozzle of two one.Nozzle processes with raw materials such as plastics king, propylene plastics, copper or alloyed copper, is installed in every layer of spinning disk top, presses 10～15 ° of sprayings of air-flow direction of rotation angle.Nozzle quantity is consistent with the every disc floret of spray cyclone tower hilllock sillar number, adorns a nozzle sleeve pipe and nozzle in the every granite vertical masonry joint.Sleeve pipe does not exceed the tower body inwall, but exceeds tower body outer wall 10～20mm.Nozzle does not exceed the sleeve pipe inner face.All nozzles are by D
In=20mm rubber tube and plastic annular header are connected.Seal with asbestos cord between rubber tube and the sleeve pipe.About spraying air velocity 26 meter per seconds,, promote the power that dust-contained airflow rotates, advances so have greater than air velocity in the circumferential weld and between the spinning disk.With the electric energy of atomizing pump, change into the kinetic energy of air-flow, the pressure loss of Gu Penwuxuanliuta is corresponding to be reduced, only 600～800 Pa Sika.Be processed with convex-concave step, collecting tank and overflow secret tunnel on granite tower body inwall and the core body outer wall respectively, the convex-concave step supports spinning disk and demist sheet, collecting tank collect water that the demist sheet throws away and the isolated water of tower body top centrifugal force and by three to eight in the secret tunnel of sump bottom to lower floor spinning disk top.And unlikelyly taken out of by flue gas.Flue-gas temperature makes the outlet flue gas not be with water below 8%.A treadle-operated tilt hammer for hulling rice body is built in the core body top, has both increased the intensity of core body, can avoid vortex flow again.Purify the back dry flue gas and drain into atmosphere through air-introduced machine and chimney; Small particle (dirt) is at tower, and inwall flows into the bottom water seal tank, effluxes or the two alkaline process processing of warp the circulating and recovering of purifying waste water through sedimentation basin.
The utility model can according to initial dust content height and emission request, can add and join vertical venturi tower or horizontal Venturi tube according to service condition, with raising system dust removing desulfuration efficiency, but the corresponding resistance that improved.The water seal tank water seal height exceeds at the bottom of the tower on the manhole 200～300 millimeters on plane, can not find time to guarantee water seal.
The utility model can be made into D
In=0.8m～5.6m all size, handle less than 1 ton/up to 200 tons/time boiler smoke.The tower wall thickness can be processed into 150～250 millimeters, purify flue gas and draw from the cat head center according to tower height, can connect the spiral case outlet, also can connect straight curved outlet, can addition granite, and pay the also available steel smoke pipe of tower and directly be connected to the air-introduced machine inlet from cat head.
Owing to adopt such scheme, make spray cyclone tower structure compactness, general desulfurizing dust-collector takes up an area of half as large, highly short half, invest for a short time more than 1/3rd, and resistance is low, the efficient height especially exports flue gas and is not with water, has saved operational and administrative expenses greatly.
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is I-I cutaway view of Fig. 1.
