本发明实施例提供的生物滴滤塔有机废气处理装置的工作原理如下：The working principle of the biological trickling filter tower organic waste gas treatment device provided in the embodiment of the present invention is as follows:

有机废气通过进气管1进入塔体内，并通过与进气管1连通的穿孔布气管2进行布气，使气体均匀地扩散到塔体中。在塔体中，有机废气经过储液槽3，然后由下至上依次经过各个填料室，在填料室内被填料24吸附降解，之后再经过塔体顶部的喷淋区，最后依次经过除雾器20、出气管19和排气筒17进入到空气中。The organic waste gas enters the tower body through the inlet pipe 1, and distributes the gas through the perforated gas distribution pipe 2 connected with the inlet pipe 1, so that the gas is evenly diffused into the tower body. In the tower body, the organic waste gas passes through the liquid storage tank 3, and then passes through each packing chamber from bottom to top in turn, where it is adsorbed and degraded by the packing 24, then passes through the spray area at the top of the tower body, and finally passes through the demister 20 in turn. , outlet pipe 19 and exhaust tube 17 into the air.

营养液经营养液喷淋管21进入塔体，然后由上至下依次经过各个填料室并与微生物接触，于是营养液携带微生物分解有机废气时产生的代谢废物和二氧化碳进入到塔体底部的储液槽3中，储液槽3中的营养液由于重力作用从出液管4流出并进入到营养液处理槽11中，由于营养液处理槽11中有藻液投放器9提供的藻类，这些藻类可以降解营养液中的二氧化碳、菌种代谢产物等二次污染物(二次污染物在微生物降解有机废气时产生)，所以营养液能够得到净化，经过净化后的营养液从营养液处理槽11溢流到出液槽13，在循环泵16的作用下，并最终通过循环管18进入到营养液喷淋管21，完成循环。The nutrient solution enters the tower body through the nutrient solution spray pipe 21, and then passes through each packing chamber from top to bottom and contacts the microorganisms, so the nutrient solution carries the metabolic waste and carbon dioxide generated when the microorganisms decompose the organic waste gas into the storage tank at the bottom of the tower body. In the liquid tank 3, the nutrient solution in the liquid storage tank 3 flows out from the liquid outlet pipe 4 due to gravity and enters in the nutrient solution treatment tank 11. Since there are algae provided by the algae liquid dispenser 9 in the nutrient solution treatment tank 11, these Algae can degrade secondary pollutants such as carbon dioxide and bacterial metabolites in the nutrient solution (secondary pollutants are produced when microorganisms degrade organic waste gas), so the nutrient solution can be purified, and the purified nutrient solution is discharged from the nutrient solution treatment tank 11 overflows to the liquid outlet tank 13, under the action of the circulation pump 16, and finally enters the nutrient solution spray pipe 21 through the circulation pipe 18 to complete the cycle.

本实施例中，出液槽13的出口处设置有出液阀14。In this embodiment, a liquid outlet valve 14 is provided at the outlet of the liquid outlet tank 13 .

Various modifications to the embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
