The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
Referring to Fig. 1, the utility model comprises and offers gas inlet 15, gas exit 2, the housing 6 of flushing pipe 5 and sewage draining exit 14, in housing 6, also be provided with the air deflector 20 that is connected with gas inlet 15, the upper end of air deflector 20 also is provided with netted all gas grid 12, the upper end of housing 6 is provided with by the upper frame 7 that is connected with high-voltage D.C. generator 1 of the high-tension insulators 4 in the high pressure inlet wire case 3, upper frame 7 is connected as a single entity by corona wire 8 and lower frame 10, corona wire 8 (negative electrode) passes from receiving electrode anode clapboard 9 centers with receiving electrode anode clapboard 9 (anode) and forms the HVDC highfield, and the lower end of each corona wire 8 also is provided with weight 11.
Introduce upper frame 7 by the HVDC that high-voltage D.C. generator 1 produces by high pressure inlet wire case 3 and high-tension insulator 4, upper frame 7, corona wire 8 and lower frame 10 have been formed the main cathode assembly of electrostatic tar remover, corona wire 8 (negative electrode) passes from receiving electrode anode clapboard 9 centers and forms the HVDC highfield with receiving electrode anode clapboard 9 (anode) and order about the highfield and be ionized near the gas in the narrowed area around the corona wire 8, produce a large amount of electronics of doing directed movement, move to receiving electrode anode clapboard 9 (anode) at a high speed, in motion process, dust in the air-flow, tar fog is forced to charged, and moves to receiving electrode anode clapboard 9 (anode) under the electric field force effect.Charged dust and tar fog arrive receiving electrode anode clapboard 9 release currents becomes neutrality, and is deposited on the receiving electrode anode clapboard 9.The water under high pressure of being introduced by flushing pipe 5 is swept away the dust and the tar that are deposited on the receiving electrode anode clapboard 9, and is discharged by sewage draining exit 14 regularly to 9 flushings of receiving electrode anode clapboard, makes that the dust more than 98%, tar are removed in the gas.Every corona wire 8 hangs with weight 11, can make corona wire 8 remain vertical and stretching state.The cation that (ionized region) is ionized out in the narrow and small district around corona wire 8 forces dust in the air-flow and tar fog lotus positive electricity and marches on towards corona wire 8.Because 98% above area becomes the negative electricity subarea,, has only the charged corona wire 8 (negative pole) that marches on towards of only a few dust and tar so dust more than 98% and tar fog march on towards receiving electrode anode clapboard 9 after charged.
For being assigned in the receiving electrode anode clapboard 9 (anode) equably, goes the coal gas that guarantees to enter, make that the air velocity in each separate electric fields adheres to specification in the receiving electrode anode clapboard 9 (≤1m/s).At gas inlet side device air deflector 20 is arranged, pass through all gas grids 12 when forcing the coal gas stream of distribution to be folded to, make coal gas stream obtain further equalization by air deflector 20.
Referring to Fig. 2, corona wire 8 of the present utility model is arranged on the concentric circles and by concentric circles cylindrical shell 6 and separates, also be provided with the receiving electrode anode clapboard 9 of isolating corona wire 8 between each corona wire 8, corona wire 8 and the receiving electrode anode clapboard 9 common HVDC highfields that form, precipitated utmost point anode clapboard 9 surrounds around the every corona wire 8, form a separate electric fields, thoroughly eliminated interference with interpolar, the electron stream that corona wire 8 is produced can have no to march on towards receiving electrode anode clapboard 9 with stopping, because the electric field effective area has occupied more than 98% of cylindrical shell cross section, handling under identical coal gas and the identical flow rate conditions, its volume dwindles greatly, and its cost has only half of shell and tube cost.
Referring to Fig. 3, evenly be provided with three high-tension insulators 4 that are mutually 120 degree in the utility model high pressure inlet wire case 3, and the pyramidal structure that high-tension insulator 4 is made for ceramic material, the effect one of tower high-tension insulator 4 is the weight that supports whole cathode assemblies, the 2nd, and cathode assembly and anode are isolated.Iron-clad thermometer 17 is housed on the high-tension insulator 4, and operating personnel grasp the temperature height at any time.Increase and decrease steam inlet can make temperature remain in the constant scope.Save steam in order to reduce heat loss, high-tension insulator 4 appearances are provided with heat-insulation layer 16.
Referring to Fig. 4, air deflector 20 of the present utility model is the flaring structure, be made up of deflector blade 13 and deflector side plate 19, and the deflector blade 13 that is arranged on the deflector 19 also increases gradually from the import its spacing that extends back.The effect of guide vane 13 is to make the coal gas that enters cylindrical shell 6 at first to meet with the guide vane 13 of camber shape and forces bending upwards.Owing to become diffusion type after coal gas enters cylindrical shell, the coal gas of its diffusion stream is along with away from air inlet, the cone angle of air-flow body enlarges thereupon, section near air inlet conical flow body is little, thereby the air velocity than rear portion section is big in succession should to locate coal gas stream, and guide vane 13 is from import department extends back, and its blade also increases at interval gradually, thereby the gas flow that each section of assurance conical flow body upwards distributes is identical, has played the effect of uniform gas.The cone angle that two deflectors are 19 consistent with the cone angle of air-flow (greater than 4～5 ° of air-flow cone angles) guarantees to enter the gas of cylindrical shell 6 all in the range of distribution of guide vane 13.
The utility model has been formed a non-homogeneous DC electric field of high pressure by corona wire 8 (negative electrode) and receiving electrode anode clapboard 9, under the effect of the non-homogeneous DC electric field of high pressure, around the corona wire 8 in the narrow and small district, make free electron in the gas be accelerated and then clash into the outer-shell electron of gas molecule, make its ionization.Along with the raising of electric-field intensity, the degree of gas ionization is stronger, and under the effect of electric field force, cation is neutralized to corona wire 8 motions, and anion is neutralized to 9 motions of receiving electrode anode clapboard.When dusty gas passed through electric field space, dust and tar fog were forced to charged, make it become charged body.Because ionization occurs in the narrow and small zone of corona wire 8 (negative electrode) on every side, thereby the space of electric field 98% is shared by negatron, moved towards receiving electrode by the dust of bear electricity, tar, be deposited on and lose electric charge on the receiving electrode anode clapboard 9 and be collected, the dust that bath is regularly amassed Shen on receiving electrode sweeps away, and then discharges by sewage draining exit 14.
The utility model can be widely used in industry unstripped gas and the process for purifying of dust and the collections of liquid mist such as chemical industry, metallurgy, building materials, coking, town gas.It is simple to operate, and power consumption is low, and is stable, and the purification efficiency height has been avoided the interpolar interference, and the effective electric field occupation rate reaches more than 98%, and under the situation that guarantees identical gas flow, identical gas speed, volume reduces, and cost reduces.
