Description

Rotary static electric air purifier

The present invention relates to a kind of gas purifying equipment, it utilizes the high-voltage corona discharge effect to remove greasy dirt, grit and oxious component in the gas, and being mainly used in the coal is the decoking oil removing and the air cleaning of semiwater gas or some piped gas in the nitrogen fertilizer plant of raw material.

Existing static decoking waste-oil scavenger adopts concentric circles tower body and fixed electrode structure more, it is corona electrode with the stainless steel wire that porcelain insulator supports that space between the concentric circles hangs several, the greasy dirt particle on each concentric circular tower wall, reaches the purpose of decoking oil removing in the electric field action deposit.This fixed electrode scrubbing efficient is low.Thereby tower body is huge, and the greasy dirt that is deposited on the tower wall is poor because of flowability, needs regularly manually to go into tower and removes, and time-consuming, labour intensity is big.

The purpose of this invention is to provide a kind of decoking oil removal efficiency height, and can remove the static decoking waste-oil scavenger of greasy dirt automatically.

The present invention adopts the technical scheme of rotation electrode and chuck heating to realize above-mentioned purpose.Decoking waste-oil scavenger of the present invention has one with motor-driven rotary main shaft, several corona electrodes that link to each other with high voltage source and several are in the receiving electrode of zero potential, alternately be fixed in couples on the main shaft and can rotate with the axis, each electrode is the netted blade construction of conductor.Each corona electrode links to each other with lead on the high-tension electricity porcelain vase by lead, quoit and brush, be in the negative high voltage current potential, receiving electrode links to each other with housing and ground connection by main shaft, be in zero potential, the housing of this equipment is the jacket structured of bilayer, can feed hot water or water vapour in the chuck to improve the flowability of greasy dirt, and the lower end of housing connects dirty jar an of storage, the tar dirt that is glided by housing wall flows in this jar, regularly opens a jar removing.

In the decoking waste-oil scavenger of the present invention, each electrode is with main axis rotation, the high pressure that is produced by high-tension transformer inserts corona electrode, produce corona discharge on this electrode, the highfield that produces around the electrode makes coal gas molecule generation ionization, wherein various grits and greasy dirt combine with anion or electronics with going up negative electricity and are attracted on the netted blade and housing wall of receiving electrode, the netted blade of this that is rotating constantly gets rid of grit, the greasy dirt of absorption to housing under centrifugal action, and be heated downslide by housing wall, dirty jar of automatic stream storage.

Static decoking waste-oil scavenger of the present invention is owing to adopt revolving net-veined leaf plate electrode, and during its fast rotational, the scope that corona influenced is much larger than the coverage that leaves standstill under the vacant state, thereby scrubbing efficient height, facility compact, and volume is little.The dirts such as tar that are deposited on the housing wall are good in the heated condition current downflow, can glide automatically, need not artificial removing.

Further specify embodiments of the invention below in conjunction with accompanying drawing.

Fig. 2 is the horizontal example structure cutaway view of the present invention.

Fig. 3 is the structural representation of the netted blade corona electrode of expression high potential line connecting relation.

Fig. 4 is a regularly switched system circuit diagram of electrode.

Among Fig. 1, Fig. 2 embodiment, housing 15 is a double layer jacket structure, main shaft 6 is contained on the

support

7 and 13 that links to each other with housing by bearing 3 and 12, and be in zero potential together with housing, the netted blade 9 of conductor and 10 alternately is housed on the main shaft 6, and insulating sleeve 27, conduction lasso 28, netted blade 10 links to each other with high-tension electricity porcelain vase 8 by electric wire 26, conductive ring 28, brush 4, electric wire 5, is in high potential.Isolated with insulating sleeve 30 between netted blade 10 and the main shaft 6, netted blade 9 directly links to each other with main shaft 6, thereby is in zero potential together with main shaft and housing.The lower end of housing is connected for dirty jar 22 with storage, both communicate with valve 23, and by valve 21 blowdowns, can feed steam or hot water by inlet tube 20 in the chuck of housing 15, also can be by electric heater 24 heating, for saving heat energy, can in chuck, adorn heat sensor (thermocouple 19), and pass through the switch of controller automatically controlled electric heater.

When semiwater gas or coal gas when import 16 feeds in this equipment chambeies, the electric field that netted blade 10 corona discharge effects form is enough to make coal gas molecule generation ionization, grit that combines with anion and greasy dirt are adsorbed on the inwall of netted blade 9 and housing 14, under action of centrifugal force, adsorbate on the netted blade 9 is also got rid of on the inwall of housing 14, and be heated along wall and flow downward, flow into storage through valve 23 and store for dirty jar 22, regularly open valve 23 promptly discharges dirt.The gas that has purified is discharged by outlet 29.

This equipment is regulated electric field by control system, and control system also has accident and cuts off the electricity supply automatically and warning function except that guaranteeing the corona discharge operate as normal.Consider tar, particularly high temperature tar and dust are adsorbed on the rotation electrode 9, may be in certain degree difficult drop-off, electric field occurring weakens, reduce the phenomenon of decoking deoiling effect, this equipment can be set up the time circuit (multivibrator) as Fig. 4 in electric control system, the electrode that phase inverter and relay J S form is switched system regularly.Electrode a and the b on Fig. 4 can self-timing ground be switched in this system.A and b by conductor 5 and housing 15 on the porcelain vase 8, are connected on

rotation electrode

9 or 10 respectively.Like this, be adsorbed on the blended tars that does not come off on the rotation electrode 9 originally, when switching to negative electricity, under the negative electric field effect, negative ionization and being ostracised, and under centrifugal action, dispose.Electrode a and b periodically constantly automatically switch, and can often keep the clean-up performance of

rotation electrode

9 and 10, keep normal corona field, keep normal decoking deoiling effect.

The present invention also can utilize high-voltage corona to make surrounding air produce a large amount of ozone except that being used for the decoking oil removing, has extremely strong sterilization, and the function of sterilization and elimination oxious component is used for the purification to air.
