Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment:
As depicted in figs. 1 and 2, be a kind of embodiment of the utility model gas cleaning plant, it is the organic pollution gas handling system with bulky grain or dust of representative that this embodiment is mainly used in paint industry, its concrete structure and operation principle as follows:
Dusty gas gathering-device 1 is provided with in the inside of building 2, building 2 outside sets gradually rotational flow and spray tower 3, Multistage filtering device 5, catalytic oxidation unit 6 and blower fan 7, dusty gas gathering-device 1, rotational flow and spray tower 3, Multistage filtering device 5, to be communicated with successively by gas transmission pipeline 4 between catalytic oxidation unit 6 and blower fan 7, the dynamical element that blower fan 7 is carried for whole system dusty gas, dusty gas through multistage classification process the most at last dusty gas change clean free of contamination air into and be released into the Nature, below just each device elaborate.
As shown in Figure 2, rotational flow and spray tower 3 comprises the multistage tower body 8 that flange (not shown) connects, be convenient to assembling and the transport of large volume spray column like this, fluid storage tank 9 is set gradually from bottom to top in the inside of tower body 8, packing layer 10, spraying layer 11, liquid mist separator 12, the lower end of rotational flow and spray tower 3 is provided with the gas inlet pipe 13 with its inner space, the upper end of rotational flow and spray tower 3 is provided with and goes out pipe 14 with the gas of its inner space, inner at rotational flow and spray tower 3, the gas inlet pipe 13 of contaminant gases spin current spray column 3 lower end enters in tower, upwards successively through packing layer 10, spraying layer 11, spraying layer 11 discharges spray liquid downwards simultaneously, waste gas and spray liquid carry out after gas-liquid two-phase fully contacts purification, finally after liquid mist separator 12 dehydrating demisting, enter next stage, tower body herein can adopt FRP or PP or PVC material to make, packing layer 10 inside is efficient, the Pall ring filler of low-resistance, in addition, the water pump 15 for the spray liquid in fluid storage tank 9 being promoted to spraying layer 11 is provided with between fluid storage tank 9 and spraying layer 11, the spray liquid be housed in lower end fluid storage tank 9 can be promoted to spraying layer 11 like this to recycle, substantially reduce the operating cost of equipment.The Main Function of this rotational flow and spray tower 3 removes the dust in gas, and especially oarse-grained gas pollutant and dust, its clearance is more than 95%.
