The specific embodiment
Below in conjunction with the specific embodiment the utility model is described in further detail.
As shown in Figure 1, the utility model is used for the gas inlet distribution device of reaction tower, comprise the gas distribution structure that is arranged in the reaction tower 4, described gas distribution structure is arranged on the top of exhaust inlet pipe 5, described gas distribution structure comprises from bottom to top stacked graticule mesh layer 2 and gas distribution packing layer 1, the periphery of described graticule mesh layer 2 and gas distribution packing layer 1 is all identical with the inwall of reaction tower 4, be fixed with on the inwall of described reaction tower 4 and support 3, described support can be made of dative stratum reticulare 2 fixing support rings, also can consist of along uniform a plurality of dative stratum reticulares 2 fixing support claws that make progress in reaction tower inwall week; The material of described graticule mesh layer 2 is stainless steel or UPVC, the mesh aperture 5 ~ 15mm of described graticule mesh layer 2, distance between peak dative stratum reticulare 2 bottom surfaces of described exhaust inlet pipe 5 is at least 500mm, the height of described gas distribution packing layer 1 is 150 ~ 400mm, the structure of described gas distribution packing layer 1 is selected Pall ring or Raschig ring, preferred heights is 250mm, and diameter is the Pall ring of 35 ~ 40m; The mouth of pipe 6 of described exhaust inlet pipe 5 can be 45 ° of openings that tilt, and as shown in Figure 2, also can be the rectangular aperture of an inverted concave, as shown in Figure 3.
Gas distribution structure in the utility model and exhaust inlet pipe 5 are used, and gas distribution structure is arranged on the top of exhaust inlet pipe 5.In order to guarantee the gas distribution effect, preferably reduce induction air flow ratio, therefore, exhaust inlet pipe 5 is needed after entering reaction tower inside by taking such as methods such as the calibers of expanding export to reduce induction air flow ratio, guarantee that induction air flow ratio can be lower than 1m/s, the mouth of pipe 6 of exhaust inlet pipe takes different cut-out directions to reduce induction air flow ratio in the utility model; Simultaneously, the pipe epithelium of gas distribution structure and exhaust inlet pipe 5 distance should be not less than 500mm.Waste gas flows after the mouth of pipe 6 of exhaust inlet pipe 5 reduces flow velocity from bottom to top, and at first by graticule mesh layer 2, the material cocoa of graticule mesh layer 2 is according to the erosion-resisting requirement selection stainless steel of reality or UPVC.This graticule mesh layer mainly contains two effects: the one, by with support fixedly come support gas distribution packing layer 1; The 2nd, can play the effect of rough gas distribution.The filler of gas distribution packing layer 1 can be selected Pall ring or Raschig ring, and the diameter of filler can be selected according to the actual pressure loss.Waste gas is through gas distribution packing layer 1 even gas distribution, in addition, when the reaction tower inner liquid medicine flows from top to bottom, on the gas distribution packing layer, can form water membrane, waste gas can further guarantee the gas distribution uniformity of waste gas, simultaneously by gas distribution packing layer 1 and the upper water film that forms thereof, also improve the time of contact of waste gas and liquid, improved reaction efficiency.Excessive for fear of the resistance by the gas distribution packing layer, the height of gas distribution packing layer 1 is unsuitable too high, preferably is controlled between the 150mm-400mm and is advisable.
The below take to the VOCs treatment engineering as example, its implementation process done specifying:
The mouth of pipe 6 of the exhaust inlet pipe 5 in the waste gas purification reaction tower 4 adopts the form of inverted concave otch pipe as shown in Figure 3, enter in the reaction tower 4 behind the mouth of pipe 6 reduction flow velocitys of waste gas through exhaust inlet pipe 5, and in tower, flow from bottom to top, behind the gas distribution structure that is consisted of by graticule mesh layer 2 and the gas distribution packing layer 1 of arranged stacked, contact with top-down spray liquid and react.Wherein, the bottom surface of the graticule mesh layer 2 of gas distribution structure bottom is 500mm apart from the pipe epithelium height of exhaust inlet pipe 5.Gas distribution packing layer 1 is comprised of the Pall ring of 250mm height, and the diameter of this Pall ring is 35-40mm.What graticule mesh layer 2 adopted is that the aperture is the UPVC net of 10mm.Can improve the waste gas uniformity in the reaction tower behind waste gas process the utility model distribution device, avoid short stream, liquid forms water film at gas distribution packing layer 1, thereby has increased reaction contact time, has improved reaction efficiency.
