Process for removing tobacco odour

Abstract

The invention discloses a process for removing tobacco odour, which comprises the following steps of: removing dust and watersoluble harmful substances or constituents in gas to be treated by using a wet scrubber, removing water mist in the gas by using a demister, oxidizing the harmful substances or constituents in the gas by using a photocatalytic odour processor, and discharging the processed gas to the air by using a main air blower. The wet scrubber is a hypergravity gas dust-removing and sulphur-removing integrated machine, the gas to be treated is washed with circulating water, and the circulating water is cooled by a cooling air blower. The photocatalytic odour processor is a tube self-cleaning photocatalytic odour processor. The hypergravity gas dust-removing and sulphur-removing integrated machine and the photocatalytic odour processor can be used independently and combined for use. Both the hypergravity gas dust-removing and sulphur-removing integrated machine (Patent No. ZL200920233065.5) and the tube self-cleaning photocatalytic odour processor (Patent No. 201010273561.0) are inventions of the applicant, have applied the national patent, and are batch-produced, and are put on the market and gained public praise.

Description

technical field [0001] The invention relates to an environmental protection device, in particular to a tobacco odor treatment process. Background technique [0002] Tobacco is divided into several categories such as flue-cured tobacco, air-cured tobacco, and sun-cured tobacco according to the different modulation methods. Tobacco in the process of humidification, dampening, shred drying, etc., produces a strong odor gas, especially the Burley tobacco modulation process will produce a more intense pungent odor. Tobacco odor gas composition is very complex, in addition to aroma, also contains a variety of harmful gases, such as furfural, furfuryl alcohol, nicotine, tar and so on. If the gas containing a large amount of harmful components is discharged into the atmosphere without treatment, it will directly damage human health. The country has promulgated a series of environmental protection regulations, and the requirements for the control of industrial gas emissions are g...

Problems solved by technology

However, the ultraviolet lamp tube of the photocatalytic reactor currently used does not have the function of self-cleaning. After a long time of use, it is covered with a layer of dust, which affects the normal use of the ultraviolet lamp tube and reduces the conversion of energy and the photocatalysis of organic matter. The efficiency of degradation conversion, in severe cases, will cause the photocatalytic odor treatment reactor to fail to work normally
