Problems solved by technology

Solvent extraction regeneration method and negative pressure regeneration method have high operating costs. At present, only high-temperature heating regeneration method is mainly used in large-scale industrial production, but the disadvantage is that the loss of activated carbon device is large during the regeneration process, and the mechanical strength of regenerated activated carbon decreases. Fiber The chemical structure of the surface changes, and the value of repeated use decreases; at the same time, the operating cost of the recycling equipment is also high, which cannot meet the general trend of energy saving and the cost requirements of enterprises

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] like figure 1 As shown, the activated carbon regeneration waste gas treatment device at normal temperature includes a shell 1, the two ends of the shell 1 are the gas inlet and outlet respectively, and a plurality of activated carbon devices 2 are arranged at intervals in the shell 1, and a vacuum is provided between two adjacent activated carbon devices 2. An ultraviolet lamp 3 and an ozone generator 4; a metal coating is provided on the inner wall of the housing 1; a fan 5 is provided at the gas outlet end of the housing 1;

[0016] The vacuum ultraviolet lamp 3 produces ultraviolet light with a wavelength of 185nm. At normal temperature, the vacuum ultraviolet lamp 3 irradiates the activated carbon device 2 to cause photolysis of the adsorbate, and simultaneously produces a large amount of hydroxyl radicals, hydrogen peroxide, and oxy...

Abstract

The invention discloses a device for waste gas treatment through normal-temperature regeneration of active carbon. The device comprises a shell, wherein two ends of the shell are respectively provided with a gas inlet and a gas outlet; a plurality of active carbon devices are arranged in the shell at intervals, and a vacuum ultraviolet lamp and an ozone generator are arranged between every two adjacent active carbon devices; a metal coating is arranged on the inner wall of the shell; and each vacuum ultraviolet lamp illuminates each active carbon device to ensure that an adsorbate is subjected to photolysis reaction and generate a lot of strong-oxidizing-property substances such as oxyhydrogen free radicals, hydrogen peroxide, oxygen ions and ozone at the same time to further react with the adsorbate, so that the regeneration of the active carbon devices at normal temperature is realized.

Description

technical field [0001] The invention relates to the technical field of industrial air purification, in particular to an activated carbon waste gas treatment device. Background technique [0002] At present, the most important method of industrial organic waste gas treatment is to use activated carbon device for adsorption and purification. After the activated carbon device is saturated, it can no longer be adsorbed. Usually, it will be saturated and fail within a week. Frequent replacement of consumables increases the operating cost of waste gas treatment in enterprises. Therefore, the use of activated carbon devices to treat industrial organic waste gas is like a car. If you can afford a car, you can't afford oil, so activated carbon waste gas treatment devices usually become decorations. For this reason, it is of great practical significance for enterprises and society to effectively regenerate activated carbon devices and achieve resource recycling. [0003] According to...
