Description
Technical field
The present invention relates to the inside critical component of a kind of flue gas purifying equipment of field of Environment Protection, be specifically related to a kind of wet cottrell flexible plate.
Background technology
Wet electrical dust precipitator is a kind of for processing the cleaning equipment containing trace dust and microparticle, it is mainly used to remove containing harmful substances such as the dust in humid gas, acid mist, drop, aerosol, PM2.5, have that efficiency of dust collection height, the pressure loss be little, behaviour do simple, energy consumption is low, movement-less part, without reentrainment of dust, be operable with below flue gas dew point temperature, can be combined with other smoke gas treatment equipment, the advantage such as versatile and flexible, one of the ideal equipment of industrial smoke pollution control, the deacidification of each industrial processes, except mist in have extensive application.Deterioration increasingly particular with China's atmosphere quality, increasingly serious and the national environmental standard of Environmental Protection in China situation day by day strict, nearly 2 years, wet static dedusting technology in China's coal-fired plant boiler smoke gas treatment system with wet desulfurizing process cooperative disposal, the application in the mercury oxide in efficiently removing a large amount of SO3 blue smoke acid mists because wet desulphurisation system produces, gypsum rain and flue gas etc. is in multiplication trend.
Wet cottrell is generally called for short WESP, and its ultimate principle and work process, with dry electric precipitation device (DESP), are divided into charged, collection and deashing three phases, and different is only its purge mode difference.Being different from the mode of DESP vibration dust-cleaning, what wet cottrell adopted is the mode of current flushing, makes pollutant remove along with the flowing of cleanout fluid.
At present, domestic board-like horizontal wet electrostatic precipitator main flow pole plate form mostly is slab construction, and pole plate material mostly is rustless steel, and this kind of maximum the haveing the drawback that of pole plate cleans the water electrode easily bifurcated because of action of gravity impact, it is difficult to form uniform moisture film at polar board surface, has a strong impact on the purification efficiency of cleaner unit.Rustless steel price is high simultaneously, and ratio is great, the cleaner unit structure comparison heaviness adopting stainless steel polar plate of cleaner unit, additionally, this kind of electrode plate structure generally adopts cleaning showers mode, easily brings electric field region splashing droplet concentration to increase, and the reactive loss of electric field increases relatively；Easily causing voltage and current to fluctuate because of spray pressure fluctuation or spray nozzle clogging, operation stability is not good enough；Spray dead angle, the relevant issues such as pole plate utilization rate is relatively low easily occur.
For the problems referred to above, it is necessary to design a kind of new wet cottrell pole plate so that it is the new construction having, to promote pole plate function and to increase pole plate height, reduce the cost of pole plate.
Summary of the invention
It is an object of the invention to do not possess current distribution function for wet cottrell dust collecting pole plate self, especially pole plate is along with highly increasing, occur that moisture film is uneven, cleaning performance is not good enough, Heavy Weight, a solution that the problems such as price is high propose, this technical scheme ensure that pole plate cleans moisture film and covers uniformly, improves cleaning performance, pole plate is lightweight, long service life and investment reduction.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of wet cottrell flexible plate, it includes entablature, current-sharing cover plate, spray header, spray header is suspended on the lower section of entablature, current-sharing cover plate is arranged on the top of spray header, it is characterized in that electrostatic precipitator pole plate is for the flexible door curtain made of cloth, is provided with door curtain made of cloth upper support pipe on the top of the flexible door curtain made of cloth, the flexible door curtain made of cloth is suspended on the lower section of spray header by door curtain made of cloth upper support pipe, on the flexible door curtain made of cloth, level is provided with tensioning tube, and the both sides of the flexible door curtain made of cloth are provided with gag lever post.
Described some tensioning tubes are horizontally arranged on the flexible door curtain made of cloth with a determining deviation, are provided with retaining ring at the two ends of tensioning tube, and the diameter of retaining ring is more than the diameter at tensioning tube two ends, excessive along tensioning tube for stopping the water on the door curtain made of cloth.
The described both sides at the flexible door curtain made of cloth are provided with location bar, and location bar couples with the two ends of tensioning tube, and location bar is the position-limit mechanism of flexible plate, can distance between controlling plate, prevent pole plate all around from swinging simultaneously, affect electric field electric discharge fluctuation, it is ensured that the stable operation of cleaner unit.
In technique scheme:
Clean current and be ejected in the concave surface of current-sharing cover plate by the hole for water spraying on spray header top, it is left to again on the surface of sparge pipe, play first time current balance function, fall the surface water of sparge pipe along tube wall stream to the flexible door curtain made of cloth be wrapped in door curtain made of cloth upper support pipe on play second time current balance function, and form uniform moisture film and cover the surface of the flexible door curtain made of cloth.The flexible door curtain made of cloth is the resistant materials such as organic synthetic fibers.
Owing to the flexible door curtain made of cloth is softer, it does not have rigidity, it is mounted with some tensioning tubes from top to bottom at the door curtain made of cloth, makes the door curtain made of cloth keep smooth, it is ensured that on the door curtain made of cloth, moisture film is uniform, for preventing water on the door curtain made of cloth excessive along tensioning tube, be close to the flexible door curtain made of cloth and retaining ring is installed over the tension tube.
For preventing pole plate from swinging, cause electric field to fluctuate, gag lever post is set at the two ends of flexible plate, limit before and after pole plate and swing, it is ensured that cleaner unit long-term stability is run.
The invention has the beneficial effects as follows: moisture film is uniform, and ash-removal effect is splendid, pole plate utilization rate is high, and lightweight, cost is low, long service life；Owing to the flexible door curtain made of cloth adopts twill face construction, the surface tension of water can be effectively utilized to overcome the gravity impact on current, guarantee current not bifurcated, and can horizontal cross flow voluntarily, make moisture film uniform fold pole plate plate face, cleaning thoroughly, pole plate is fully utilized completely, thus improve the work efficiency of cleaner unit.
Below in conjunction with Figure of description, the present invention will be further described.
