[0030] Please refer to figure 1 , this embodiment provides a biotrickling filter device 100 , which includes a biotrickling filter body 120 and a circulation transmission system 140 . Wherein, the bio-trickling filter body 120 is the main device for waste gas treatment, and the circulation transmission system 140 communicates with both ends of the bio-trickling filter body 120, so that the bio-trickling filter body 120 can cyclically degrade the waste gas, improving the efficiency of the bio-trickling filter device 100. Conversion rate of waste gas treatment.

[0031] Specifically, continue to refer to figure 1 The two ends of the bio-trickling filter body 120 are respectively provided with a waste gas inlet 121 and a degradation gas outlet 129, and a cavity 122 is arranged inside, and the waste gas inlet 121 and the degradation gas outlet 129 are both connected to the cavity 122. It should be noted that the waste gas enters the cavity 122 from the waste gas inlet 121 , unde...

[0043] Please refer to image 3 , this embodiment provides a bio-trickling filter device 200, which is substantially the same as the bio-trickling filter device 100 provided in the first embodiment, the difference is that the bio-trickling filter device 200 provided in this embodiment is at the waste gas inlet 221 An activated carbon adsorption layer 233 is also provided.

[0044] Further, an activated carbon adsorption layer 233 is provided at the waste gas inlet 221 and placed between the first valve 223 and the cavity 222 to make the waste gas treatment effect of the biological trickling filter device 200 better. It should be noted that the activated carbon adsorption layer 233 is arranged before the exhaust gas enters the cavity 222, mainly for the first pretreatment and adsorption of the exhaust gas, and its main adsorption objects are sulfur dioxide and nitrogen oxides, etc., which makes the biological trickling filter 200 The exhaust gas treatment capacity is further i...

Abstract

The invention provides a bio-trickling device and a waste gas treatment system, relateing to the field of waste gas treatment. According to the bio-trickling device, an alkaline adsorption layer and a biological stuffing composite layer are arranged inside a bio-trickling body, so that waste gas can be subjected to adsorption filtration with carbon oxide and sulfide and biodegradation treatment of other harmful gases; a cyclic transmission system is communicated with two ends of the bio-trickling body and is provided with an atomized vapor delivery belt, so that waste gas inside the bio-trickling body can be cyclically degraded, and the waste gas treatment effect can be improved; and the bio-trickling device has a better waste gas treatment effect since the activated carbon adsorption layer is arranged at a waste gas inlet. Therefore, the waste gas treatment system comprising a plurality of bio-trickling devices which are designed in a parallel connection manner can be used for quickly and effectively carrying out adsorbing degradation treatment on waste gas, has the advantages of simple treatment process and low cost, cannot easily cause secondary pollution, and can be mainly popularized and applied to the field of industrial waste gas treatment.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a biological trickling filter device and a waste gas treatment system. Background technique [0002] With the rapid development of social economy, air pollution has become more and more serious, especially in energy, chemical and other industries, the exhaust gas emitted is the most serious air pollution. Like the smog that has become more and more serious in recent years, a large part of it is caused by the excessive emission of waste gas into the atmosphere during the production and life of human beings. Therefore, it is urgent to treat the waste gas in a proper way. [0003] Usually, common exhaust gas pollutants include sulfides, nitrogen oxides and other organic harmful substances, and there are many methods for exhaust gas treatment, such as absorption method, catalytic combustion method and neutralization method, etc. However, The shortcomings of these current methods a...
