Embodiment Construction

[0025] The technical solution of the present invention will be further technically described below through the embodiments and in conjunction with the accompanying drawings.

[0026] like figure 1 As shown, the present invention includes: filter device 1, photolysis device 2, spray device 3, spray pipe 4, packing layer 5, oxidant storage device 6, ultraviolet light generating device 7, water pump 8, fan 9. The rubber waste gas first passes through the filter device 1 to remove dust such as carbon black and sulfur in the waste gas, ensuring that the subsequent device will not be blocked; the rubber waste gas after dust removal is passed into the photolysis device 2, and the ultraviolet beam can destroy benzene and phenols. , mercaptans, non-methane total hydrocarbons and other pollutants to degrade them into low-molecular substances, CO 2 and H 2 O, to achieve the purpose of preliminary removal of malodorous substances in the rubber waste gas; the spray water generated by the...

Abstract

The invention discloses a rubber exhaust gas purifying device and method, and belongs to the field of environment protection. The rubber exhaust gas purifying device mainly comprises a filter device, a photodecomposition device, a spraying device, an oxidant storage device, a UV ray generating device, and a blower fan. At first, rubber exhaust gas is introduced into the filter device to remove dusts so as to guarantee the continuous and stable operation of subsequent purifying devices; then the rubber exhaust gas is delivered to the photodecomposition device to degrade the pollutants primarily; finally the rubber exhaust gas is delivered to the spraying device to radically degrade VOCs in exhaust gas; clean gas is discharged out of the device by the blower fan; the organic pollutants in the wastewater generated during the spraying process are radically eliminated under the cooperation of UV rays generated by the UV ray generating device and an oxidant stored in the oxidant storage device, and clean water is returned to the spraying device. The provided rubber exhaust gas purifying device can effectively degrade dusts, stinky substances, and VOCs in rubber exhaust gas; and has the advantages of compact structure, low cost, no secondary pollution, and strong adaptability. The stricter atmospheric emission standards can be met.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a rubber waste gas purification device and method. Background technique [0002] In the vulcanization and rubber mixing process of rubber products, process exhaust gas is generated. The pollution factors include: carbon black, sulfur and other dust, and pollutants such as benzene, phenols, mercaptans, and non-methane total hydrocarbons. Due to its emission characteristics It is intermittent and has the characteristics of large air volume and low concentration, which seriously pollutes the factory environment and the health of operators. [0003] At present, common rubber waste gas purification technologies include: wet oxidation method, activated carbon adsorption method, low temperature plasma cracking method, UV photolysis method, ozone oxidation method, etc. [0004] The wet oxidation method uses a strong oxidizing solution such as sodium hypochlorite to spray the wast...
