Abstract
The utility model relates to a compound type dust and sulphur removing device, which solves the problems of no thorough dehydration, much water carried by a fan and difficult ash cleanness of an existing dust and sulphur removing device adopting a selfexciting type. The utility model comprises the connection of a one-stage dust and sulphur removing device, a two-stage gas fog separator for removing dust and a venturi injector, wherein, an upper cyclone cap is connected with a water retaining ring, a cylinder body of a dust remover and an air lock, forming the one-stage dust and sulphur removing device; a lower cyclone body is connected with a lower dewatering body, forming the two-stage gas fog separator for removing dust. Thereby, the integration of dust, sulphur and water fog removal can be realized.
Description
The utility model is a kind of combined type dedusting desulphurization plant.
Current, China's prevention and control of air pollution emphasis is the dedusting and the desulfurization of flue gas.And desulfurization and dedusting adopts auto-excitation type more now, through utilization and feedback information for many years, there are following several shortcomings in the auto-excitation type desulfurizing dust-collector: 1, dehydration is not thorough, make fan belt water serious, particularly in the winter time, blower fan exposes outdoor and easily causes draught fan impeller to freeze to lose balance and damage blower fan.2, deashing difficulty, auto-excitation type desulfurizing dust-collector have two kinds of purge modes, but two kinds of purge modes are all imperfect.The one, adopt mechanical scraper-type; The 2nd, adopt butterfly valve type.
Scraper-type: because chain soaks in having corrosive water for a long time, easily cause the chain corrosion serious, move dumb, and short-term renewal cost height.Butterfly valve type: because butterfly valve work down in off position, lime-ash needs regular discharge, because deduster sidewall vibration for a long time causes lime-ash at butterfly valve place caking, makes ash discharge not smooth.Need when serious to go to lead to wooden stick or iron staff, grey oar flashes, and is promptly dangerous also unhygienic.Whole preservative treatment easily comes off, and causes deduster easily to rot at short notice, reduces service life.
The purpose of this utility model is, solves above-mentioned existing existing problem, and a kind of combined type dedusting desulphurization plant is provided.
The utility model is achieved in that and comprises the primary dust removing devulcanizer, two-stage dust removal aerosol separator, and venturi-type eductors connects and composes.Last whirlwind cap and retaining ring, deduster cylindrical shell, flapper connect and compose the primary dust removing devulcanizer; Lower cyclone body, the body that dewaters connects and composes two-stage dust removal aerosol separator down.
Advantage of the present utility model is: realize that 1, dedusting, desulfurization and dehydration mist are integrated; But 2, both dry-running, but also wet type operation, and wet dust removal efficient is higher than dry type.3, the optimum condition that realizes spraying, wash multiple deduster mechanism and deposit effect.4, this device can make air-flow be evenly distributed, but high speed whirlwind aerosol centrifugation again.5, make full use of air flow at high speed characteristic, aerosol separates, rational air inducing mode, avoid fog to draught fan impeller corrosiveness; 6, adopt the acid-resistant anticorrosion paint spary of development newly, effectively solve the sour problem; 7, the pressure loss is little, the processing air quantity is big; 8, low liquid-gas ratio, calcium current ratio are saved the energy; 9, cleaning solution is recycling, non-secondary pollution.
The drawing explanation:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a vertical view;
Fig. 3 is the structural representation of body spray;
Describe in detail below in conjunction with accompanying drawing:
As shown in the figure, comprise primary dust removing devulcanizer 1, two-stage dust removal aerosol separator 2, venturi-type eductors 3 connects and composes.Last whirlwind cap and retaining ring 6, deduster cylindrical shell 4, flapper 10 connect and compose primary dust removing devulcanizer 1; Lower cyclone body 8, the body 9 that dewaters connects and composes two-stage dust removal aerosol separator 2 down; On deduster cylindrical shell 4 walls, be provided with inspection door 7; Body spray 5 is installed in deduster cylindrical shell 4.Venturi-type eductors 3 roles are: dusty gas is when passing through the aditus laryngis of venturi-type eductors, because constriction in flow area, gas is quickened, thereby when making the umbrella shape adjustable nozzle of dusty gas in being arranged on venturi-type eductors, rush at the deduster inner chamber rapidly.Because dusty gas atomizes tiny particle by nozzle the time fully, increases the weight of the weight of dust, impels dusty gas to rely on the deadweight of dust to hang in deduster downwards, reaches the purpose of a part of dedusting.Deduster cylindrical shell 4: gas underspeeds in deduster, makes the dust that atomizing increases the weight of in venturi-type eductors that certain fall time be arranged.Body spray 5: after dusty gas enters deduster at a high speed in the venturi-type eductors, removed most of dust, some weight light (being floating dust) is not removed, this part dusty gas, under the effect of high-pressure fog, sufficient and fog is referred and synthesized together, has increased the surface density of dust, through the dust removing effects that reaches higher that presses down of aerosol.Last whirlwind cap and retaining ring 6: under the effect of blower fan, some gas that contains water smoke to circulate, be provided with retaining ring, make a part contain the gas of water smoke, separating through reaching certain aqueous vapor behind the retaining ring on the top of deduster along deduster.And through the gas after the dehydration by on quicken to enter in the secondary ash collector behind the whirlwind cap.Backspin endosome 9: gas dewaters under process behind the body, because gas slows down in deduster speed,, the gas of purification is flow through in the elbow of reducing through being arranged on the buffer bent in the lower body, and body wall falls under the aqueous vapor of a little edge, thereby reaches the centrifugation of secondary aerosol; Flapper 10: adopt the mode of water seal to lock gas, the water that a second wash water of venturi-type eductors 3 and spraying usefulness is separated with aerosol all is back to and melts in the gas pond, promptly recirculation water with lock gas and once finish.
Venturi-type eductors is installed in cylindric primary dust removing devulcanizer tangential direction.After flue dust enters venturi-type eductors,, improve the flow velocity of flue dust greatly because venturi-type eductors reducing place sectional area dwindles suddenly.Realize high cyclone dust removal after flue dust enters the primary dust removing devulcanizer, big grit gets rid of the wall to deduster under action of centrifugal force, falls to collecting by deadweight.
Sprayer unit is housed in the venturi-type eductors.Flue gas by the time, flue dust fine particle and water smoke affinity strengthen weight of dust, after helping this part flue dust and entering the primary dust removing devulcanizer, also by the whereabouts dedusting of conducting oneself with dignity.
Sprayer is installed on dust-removing desulfurizing device top, and sprayer sprays the desulfurizing agent of preparation by a certain percentage; Flue dust in dust-removing desulfurizing device from bottom to top at a high speed rotation run into and carry out behind the desulfurizing agent affinely, remove SO in the flue gas
2
Flue dust is through the primary dust removing desulfurization, remove big dirt after, after entering two-stage dust removal aerosol separator 2 tangential direction communicating pipe, carry out two-stage dust removal, remove than granule.The moisture content of flue gas is removed through the aerosol separator, and the flue gas of water content does not enter flue through air-introduced machine.
