Background technique
Producer gas is the indispensable raw material of coal chemical industry, since the dust in coal gas mentions gas chamber and chemical industry
It refines equipment and generates harm, it is therefore necessary to be removed before entering cabinet, its dust depth is reduced to 1mg/m3Below.Currently, being used for coal
The equipment of gas purification mainly has cyclone dust collectors, wet scrubbing deduster and bag filter, and cyclone dust collectors are generally as pre-
Deduster uses, and wet scrubbing deduster mainly uses the dust-extraction units such as stuffing washing tower, removes the dust in coal gas, can generate
A large amount of washes, operation energy consumption are also higher.Bag filter is also easy to produce " leak-off pocket " phenomenon, and outlet dust concentration often surpasses
Mark.Wet electrical dust precipitator is used in purification system, the dust concentration in coal gas can be effectively reduced, while greatly reducing system
In water consume and power consumption, and meet requirement of the system to cleaner safety.
Summary of the invention
The purpose of this utility model is to provide a kind of wet electrical dust precipitators of high pressure gas purification, can using the device
With the dust in effective coal gas, the dust concentration in coal gas is made to be less than 1mg/m3, stringent to gas quality to meet coal gas user
Requirement.The device has the advantages that high-efficient, good reliability, water consume are low, running resistance is small.The device is in wet electrical dust precipitator
Auxiliary electrode is increased in corona discharge electrode, improves the driving speed of dust in the electric field, and improve efficiency of dust collection.In anode plate
Centre is provided with two grooves vertically downward, improves the intensity of pole plate.Shell of dust remover uses cylinder type, Ke Yishi
The requirement for answering high pressure gas to purify.
The utility model is realized by following scheme:
Coal gas enters in deduster from deduster entrance, via the airflow channel that corona discharge electrode and dust collector pole form, in height
Press corona discharge and the dust charged process completed under the action of DC power supply, it is charged after dust under the action of electric field force to receipts
Dirt polar motion is simultaneously captured.There is nozzle in the top layout of electric field, the interior water mist sprayed can effectively wash pole plate and catch
The dust of collection.It is small in the variation of dust catching area electric-force gradient due to increasing auxiliary electrode in wet electrical dust precipitator corona discharge electrode,
Electric field strength is more uniform, therefore Charged can obtain constant driving force, to pole plate under the effect of consistent electric field power
The more conventional electric precipitator of process " turbulence " phenomenon of movement is weak, and submicron particle lesser for partial size, turbulence intensity is small, institute
To improve its arresting efficiency.Its dust collecting pole plate is equipped with windproof ditch using c-type plate, c-type plate both sides are widened, it is possible to reduce after trapping
The secondary of dust carries under one's arms phenomenon, and in order to improve the bending strength of pole plate, groove is located among pole plate, reduces pole plate in electric field
In by gas temperature generate thermal deformation.It is designed with coal gas explosion venting device on the air inlet and air outlet of deduster, ensure that and set
Standby safety.Shell of dust remover uses cylinder type, and bearing capacity is improved to 35kPa or more.Air outlet is equipped with hundred
Leaf window dehydration device can remove the water mist in coal gas and improve the calorific value of coal gas.
The utility model is compared with existing coal gas electrostatic precipitation technology, has the advantage that its corona discharge electrode with auxiliary electricity
Pole improves the arresting efficiency to submicron particles, and groove is equipped on dust collecting pole plate, reduces pole plate in the electric field by coal gas
The thermal deformation that temperature generates.
