Abstract
A kind of drum type brake half wet process electrostatic precipitator, belongs to waste gas pollution control and treatment and environmental protection technical field.The method is by drum type brake dust collector pole horizontal positioned, its axis goes out to place corona discharge electrode, cylinder dust collector pole bottom is immersed in aqueous solution, cylinder dust collector pole constantly rotates, guarantee dust collector pole surface is all the time by aqueous solution moistening, and when the food and drink waste gas containing oil droplet enters this electrostatic precipitator, oil droplet therein and granule are caught by the liquid film on cylinder dust collector pole surface, when cylinder dust collector pole rotates to the aqueous solution liquid level of bottom, the oil droplet and the granule that are caught are eluted.This electrostatic precipitator solves common electrostatic precipitator dust collector pole and have accumulated the problem that greasy dirt is difficult to clean.
Description
Technical field
The present invention relates to a kind of drum type brake half wet process electrostatic precipitator, belong to waste gas pollution control and treatment and environmental protection technical field.
Background technology
Along with China's rapid development of economy, the gray haze of China big and medium-sized cities, developed area and basic industries close quarters is empty
Gas pollutes the most serious.Along with China is continuous for restriction green technology increasingly strict, relevant and the device of SOx and NOx emission
Coming into operation, in China's atmospheric environment, the gross contamination emission of SOx and NOx reduces year by year, but, from current monitoring knot
Fruit sees, the gray haze of each section of China's Yangtze River Delta, Pearl River Delta and Jing-jin-ji region is polluted and is not apparent from alleviating, and the people have been arrived in serious threat
Many healthy and economic sustainable developments.
The progress of research of tracing to the source polluted along with the current Brownish haze of current China, oil droplet and VOCs discharge that food and drink causes are gradually
People are understood and are paid attention to.The cooking method of many distinct Chinese characteristics (decoct, fry, fried) can produce Organic aerosol to air
Directly discharge, this discharge is multiple is born in territory, densely populated area and drain time is concentrated very much, so this type of pollutes local
Air quality deterioration has sizable effect.At present, purification and the process of food and drink waste gas has shown significant technical need.
Containing a large amount of oil droplets and VOCs in food and drink waste gas, oil droplet therein has the highest viscosity because of the oxidation of high temperature, cooling
After be easy to adsorbing material surface formed continuous oil film, the filter gap of blocking material and absorption duct, this cause filter membrane and
The materials such as activated carbon are poor effect in the process of food and drink waste gas.Additionally, common food and beverage enterprise has installed complete convulsion dress
Put, be therefore available for exhaust-gas treatment module use gas pressure drop very limited, the occupation of land of module also tend to it cannot be guaranteed that, therefore eat
The module of drink exhaust-gas treatment needs to have concurrently that pressure drop is low, take up an area little and flexible feature.
Electrostatic precipitation technology be considered owing to vapour lock is the least process food and drink waste gas important technology, this technology in terms of droplet removal also
Achieve and well apply effect.Electric precipitation scheme is considered as in the enviromental protection enterprise being much devoted to food and drink waste gas pollution control and treatment at present
The most reliable and the most ripe technical scheme.Similar with general electrostatic precipitation, the electrostatic precipitation technology for food and drink waste gas pollution control and treatment is also
Utilizing corona discharge electrode by the oil droplet in waste gas and charging particle, then under the effect of electrostatic force, oil droplet and granule will be deposited in dust collector pole
On plate, thus complete the removal of oil droplet and granule.But it being different from common industrial electro dedusting, food and drink waste gas electric precipitation processed
Be deposited in journey on pole plate is oil droplet and the granule of thickness, and this, by forming the oil film of one layer of thickness on dust collector pole, is difficult to pass through
Physical method is removed, and therefore, this electric precipitation needs periodically to take the thickness greasy dirt cleaned on dust collector pole apart, and this gives steady in a long-term removing
Dirt operation brings inconvenience.Additionally, when greasy deposits is more, the continuous oil film formed probably at device interior by electricity
Dizzy turn between pole and dust collector pole, thus cause cremating electric discharge likely initiation fire.Therefore food and drink waste gas pollution control and treatment it is currently used for
Ripe electric dust collector in inside mostly equipped with fire alarm installation.
While giving full play to the advantage that electric cleaner effect is outstanding, pressure drop is little, how to be avoided that again that its pole plate is difficult to clean, easily
The shortcoming of initiation fire？This is to put a difficult problem in face of food and drink waste gas pollution control and treatment technical field research worker at present.The present invention is led to
Cross a bottom to be immersed under absorbing liquid liquid level and rotating cylinder does dust collector pole, can successfully solve dust collector pole greasy dirt and clean
Problem, be distributed in absorbing liquid additionally due to greasy dirt is emulsified, the most thoroughly stopped because spark discharge and breaking out of fire hidden
Suffer from.
Summary of the invention
It is an object of the invention to be immersed in the subsurface rotor of absorbing liquid as dust collector pole by bottom, it is thus achieved that a kind of low gas
Resistance, high flux and the novel half wet process electrostatic precipitator of high oily waste degradation ability.This module is not required to clean dust collector pole, operates one section
Only need to change after time absorbing liquid just can, additionally due to greasy dirt has been dispersed in absorbing liquid, thoroughly stopped cleaner unit breaking out of fire
Hidden danger, be especially suitable for the aerosol droplet in kitchen fumes is removed.
