Description
[technical field]
The present invention relates to printing and dyeing industry field, particularly a kind of purifying dust-removing device for the treatment of waste gas.
[background technology]
Printing and dyeing industry can produce a large amount of waste gas in process of production, if these waste gas directly discharge in air, can cause severe contamination to atmospheric environment, especially the waste gas of forming machine, wherein containing mist of oil, fiber, steam, dust and SO
2, N
2o
xdeng pernicious gas, therefore, purified treatment must be carried out to waste gas.
Publication number is 103817005A, publication date is that the patent of invention " a kind of plate Guan Shuliu Wet-type high-efficient purifying dust-removing device " of 2014-05-28 discloses a kind of plate Guan Shuliu Wet-type high-efficient purifying dust-removing device, comprise housing, it is characterized in that being provided with in described housing the anode vertically arranged to gather dust mechanism, anode mechanism of gathering dust is the plate tubular construction formed by dust collection plate, anode gather dust mechanism plate pipe between be provided with and vertically arrange and the cathode line at belt discharge tip, on the cathode girder of the upper end side fixed thereon of cathode line, and the lower end of cathode line is fixed on tension frame thereunder, cathode girder is connected with high voltage supply system by wire, cathode girder, cathode line and tension frame form cathod system.The anode of this invention mechanism of gathering dust is that the anode forming tubular structure by horizontal anode dust collection plate and longitudinal anode dust collection plate independent assortment gathers dust mechanism, the Figure of description 2 being aided with this invention can find out that its horizontal anode dust collection plate is mutually vertical with longitudinal anode dust collection plate, form multiple coffin, each coffin has four faces and four angles, there is such problem in it: even if the cathode line arranged between plate pipe is located at the center of coffin, cathode line cannot be equal to the horizontal anode dust collection plate of its surrounding or the distance of longitudinal anode dust collection plate, and cathode line is connected to high voltage source, its electric field produced is all volt up to ten thousand, all know for those skilled in the art, such distribution mode must cause the impurity such as the soot particles in waste gas to concentrate the place be adsorbed on cathode line close together, because the electric field formed between cathode line and the dust collection plate of close together is stronger, and other distant places, such as four angles and neighbouring dust collection plate thereof, and the electric field formed between cathode line is more weak, then be difficult to play suction-operated, namely its anode real onset area of mechanism that gathers dust is less, certainly will pick-up performance be affected and cause the wasting of resources.Meanwhile, although the lower end that this invention discloses its cathode line is fixed with tension frame, the specifically structure of its tension frame unexposed.Existing tension frame structure is multiple, and more common a kind of structure is: cathode line bottom connects one and heavily cuts or polish jade with an emery wheel, by the weight tensioning cathode line of heavily cutting or polish jade with an emery wheel.Due to when waste gas enters purifying dust-removing device all with certain wind speed, and it is also large heavily to cut or polish jade with an emery wheel the large therefore windage of area, certainly will cause cathode line slight jitter, thus cause the pitch smaller of cathode line and part dust collecter component, although spacing change is less, due to mechanism of gathering dust being stained with the impurity such as oil smoke, very easily conduct electricity, and cathode line connects the high pressure of volt up to ten thousand, pitch smaller, creep age distance is just little, therefore, as easy as rolling off a logly cause instantaneous pressure, interrupt cathode line and even put a little on fire, there is serious potential safety hazard.Meanwhile, heavily stone roller is general by cement production systD, and one is in hot environment, is subject to the corrosion of the sour gas such as oil smoke, aqueous vapor, SO2 simultaneously, as easy as rolling off a log expansion, even pulverizes, and needs often to change.Therefore, existing strainer is short for service life, and unstable, easily causes electric discharge on fire.
