Abstract
The cyclone separating combined high-voltage electrostatic dust-collecting equipment is equipped with cyclone separator which can be combined with high-voltage electrostatic separator and can be used for making operation, the cyclone separator firstly can be used for making primary preseparation of dust-containing waste gas, then further making high-voltage electrostatic dust-collecting.
Description
The utility model relates to a kind of high-pressure static cleaner, particularly a kind of combined high pressure electrostatic dust collection equipment with cyclone separator.
Known high-pressure static cleaner has tubular type high-voltage electrostatic dust separator and two electric field high-pressure static cleaner.The tubular type high-pressure static cleaner is little because have only the one-level high-pressure electrostatic precipitation to handle air quantity.And two electric field high-pressure static cleaners, as Chinese patent CN86104221, improved efficiency of dust collection, but to increase by a cover high-voltage power-supply unit owing to increased an electric field, complex structure manufacturing cost height, and the high speed swirling eddy directly pours internal electric field, slackened the effect of electric field force, fails to reach the dust removing effects of expection.
The purpose of this utility model provides a kind ofly handles that air quantity is big, efficiency of dust collection is high, the cyclone separating combined high pressure electrostatic dust collection equipment of low cost of manufacture simple in structure.
According to electrostatic dust collection equipment of the present utility model, at the top of inner pipe passway and air inlet and inner pipe passway an axial cyclone separator is set coaxially, in the annulated column space that forms between the pipe outside and the outer cylinder body inwall in the dedusting static electric field is based upon, outer tube inner wall and interior pipe constitute the positive electrode of ground connection, the prickle negative electrode hangs and is pulled in the annulated column space, air outlet is arranged on the outer cylinder body top-side, become the side direction air outlet, following ash bucket is provided with isolates awl, prevent to deposit field of dust, the outer cylinder body top is provided with the vibration dust-cleaning device that deashing is used.
The off-gas flows that contains high concentration dust is directly gone into cyclone separator through air inlet, form " whirlwind " of rotation at a high speed by cyclonic separation gas, inject inner pipe passway, oarse-grained dust particle is thrown on the inner tubal wall under action of centrifugal force, sink to down ash bucket along tube wall after the stall, ash bucket isolation awl turned back to the electric field region that forms between inner/outer tube under short grained dust particle reached with " whirlwind " air-flow.Waste gas through cyclone separator is at first separated by one-level like this, has reduced to inject the concentration of dust of static place.The dust-contained airflow that turns back to electric field region rises along annulated column shape electric field region spiral, dust particle is charged under the effect of high-voltage electrostatic field, and be attracted to and be agglomerated into big particle on the positive and negative electrode gradually, under the shake of dust-collecting and vibrating device, overcome the buoyancy of ascending air, be deposited to down ash bucket by self gravitation.Like this, waste gas at first separates through the one-level of cyclone separator, has reduced dust content, thereby has improved further electrostatic precipitation efficient, and replaced internal electric field with simple cyclone separator, simplifies the structure, and has reduced manufacturing cost.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the following cutaway view according to the utility model cyclone separating combined high pressure electrostatic dust collection equipment.
Fig. 2 is the cutaway view along A-A line among Fig. 1.
Fig. 3 is the profile along B-B line among Fig. 1.
Fig. 1 has represented the overall formation of the utility model embodiment.Comprise air inlet 1, cyclone separator 2, high-tension electrostatic separator 3, vibration dust-cleaning device 4 and following ash bucket 5 according to cyclone separating combined high pressure electrostatic dust collection equipment of the present utility model.Air inlet 1 is connected on the cyclone separator 2 coaxially, the top of pipe 6 in the interior pipe hollow passageway 7 of cyclone separator 2 and high-tension electrostatic separator 3 is co-axially mounted on.High-tension electrostatic separator 3 is made up of interior pipe 6 outer cylinder bodies 8 and negative pole assembly 9.Inwall 10, outer wall 11 that cylindrical outer cylinder body 8 has columnar steel plate to make, filling heat insulating wall 12 between the inside and outside wall, heat-insulation layer 12 can be made with various insulation materials, outer cylinder body 8 is provided with rectangular lateral air outlet 13 near the sidewall at top, and end face is provided with the fixedly support 21 of vibration dust-cleaning device 4.In pipe 6 be tightly connected with one heart at the top with outer cylinder body 8 and be in the same place, negative pole assembly 9 comprises many stainless steel barbed nail corona electrodes 14, goes up lower lift ring 15, insulation davit 16 and electrode back-moving spring 17.Many corona wire 14(present embodiment is 6) every two ends are connected respectively on the upper and lower suspension ring of being made by round steel 15 evenly distributedly, in the annulated column shape space that in insulation davit 16 is stretching in abreast by back-moving spring 17 and suspension rod 18, forms between pipe 6 and the outer cylinder body inwall 10, bearing of trend is parallel with inside and outside barrel, and goes up lower lift ring 15 and interior pipe and outer tube wall concentric (as shown in Figure 1, 2).Back-moving spring 17 is fixed on down on the crossbeam 19 of ash bucket 5, and suspension rod 18 is fixed on the base of vibration dust-cleaning device 4.Following ash bucket 5 is connected with the lower ending opening of outer cylinder body 8 hermetically, is provided with in the following ash bucket 5 to isolate awl 22, and in order to prevent depositing raising of ash, ash hole 23 is arranged on down ash bucket 5 bottom, and following ash bucket arranged outside has annular ledge 24.
As shown in Figure 2 the axial line of rectangle air outlet 13 be 30 ° of angles through plane, 4 davit 16 places.Fig. 3 shows the uniform situation of barbed nail corona electrode, and this embodiment is provided with 6 corona wires, and the 6--18 bar can be set.Upper lift ring 15 is through linking to each other with the electrode (not shown) of outer cylinder body insulation and the negative pole of high voltage source, outer cylinder body is joined by the ground connection positive pole of electrode (not shown) and high voltage source, and the equipment run duration forms the high-voltage electrostatic field between barbed nail corona electrode and interior pipe, outer tube inner wall.Vibration dust-cleaning device 4 flexibly is fixed on the support 21 through overcompression spring 20.
Equipment is in service, the dust-laden exhaust gas air-flow is injected cyclone separator 2 by air inlet 1, under the effect of high velocity air, form " whirlwind " of rotation at a high speed, pipe hollow passageway in injecting, because action of centrifugal force is thrown oarse-grained dust particle on inner tubal wall, sink to down ash bucket 5 after the stall, so at first by cyclone separator cutting out partial bulky grain dust particle, swirling eddy after this one-level is separated, turn back to the annulated column shape space of electrostatic separator behind the isolation awl under reaching in the ash bucket 5, and spiral rises, under the effect of electric field force, dust particle in the air-flow is charged, and just be attracted to, negative electrode (outer tube inner wall, the interior pipe outside and barbed nail corona electrode) on, be agglomerated into bigger particle gradually, under the vibration of vibration dust-cleaning device, shaken off in following ash bucket, through one-level separate and electrostatic precipitation after cleaning gas tream by upper side to the air outlet device for transferring.
