VOC (volatile organic compound) waste gas treatment system

Abstract

The invention discloses a VOC (volatile organic compound) waste gas treatment system. The VOC waste gas treatment system sequentially comprises a fan, a padding spray tower device, an ultraviolet activated carbon integrated device and a purified gas discharge opening, wherein the fan is connected with a VOC waste gas source; the padding spray tower device is connected with an air outlet of the fan; the ultraviolet activated carbon integrated device is connected to an air outlet of the padding spray tower device; the purified gas discharge opening is connected to the ultraviolet activated carbon integrated device. Waste gas is treated efficiently by the design of combining the padding spray tower with the ultraviolet activated carbon integrated purifier. Firstly, the padding spray tower is used for spraying washing; organic waste gas is dissolved into a purifying liquid well by multi-surface hollow spheres; then air water of a defogging layer is matched to share efficiently, so that gas after primary treatment is obtained by the padding spray tower. The gas after primary treatment is treated by the ultraviolet activated carbon integrated purifier, and clean gas reaching the standard is discharged out. The size of the device is reduced; the waste gas treatment efficiency is high; the purification cost is reduced; the purification standard reaching effect is ensured.

Description

technical field [0001] The invention relates to the technology in the field of environmental protection, in particular to a VOC waste gas treatment system with good effect, low operating cost and favorable for the popularization of waste gas treatment. Background technique [0002] Volatile organic compounds are defined as any organic compounds with a boiling point lower than or equal to 250°C under standard atmospheric pressure, referred to as VOCs. At present, activated carbon adsorption, ultraviolet deodorization, etc. are usually used. However, in the field monitoring of many furniture companies, it is often found that the phenomenon of exceeding the standard is very serious. Enterprises frequently replace activated carbon, but still exceed the standard, even in enterprises that have not started spraying. In some cases, the results of on-site monitoring are all slightly exceeded. [0003] After research and analysis, it is found that the existing exhaust gas treatment p...

Problems solved by technology

At present, activated carbon adsorption, ultraviolet deodorization, etc. are usually used. However, in the field monitoring of many furniture companies, it is often found that the phenomenon of exceeding the standard is very serious. Enterprises frequently replace activated carbon, but still exceed the standard, even in enterprises that have not started spraying. In some cases, the results of on-site monitoring are all slightly exceeding the standard

[0003] After research and analysis, it is found that the existing exhaust gas treatment process has shortcomings. The activated carbon absorbs VOCs and also stores them in the gaps of the activated carbon. The clean wind blowing through them will desorb the adsorbed VOCs.

With the improvement of emission standards, enterprises need to gradually increase the activated carbon layer as needed, and the frequency of activated carbon replacement is also gradually increasing, correspondingly, the cost of waste gas treatment is also increased several times or even ten times
