Problems solved by technology

However, the discharge of industrial waste gas mostly presents the characteristics of large air volume and low concentration, which poses the primary problem for the subsequent waste gas treatment process: how to quickly and efficiently concentrate these exhaust gases? Domestically, the activated carbon adsorption method is often used in this field, and several activated carbon adsorption beds are usually operated in parallel, which requires huge equipment and occupies a large area
Moreover, due to the defects in the adsorption capacity and mechanical strength of activated carbon, the service life of the equipment is short, and frequent replacement of adsorbents increases the operating cost and inconvenience of operation for the enterprise.

Embodiment 1

[0039] A new type of enrichment wheel uses the self-developed aminated activated carbon fiber material to make the main part of the wheel, uses plexiglass to make the support of the device, functional partitions and protective materials for the main body of the wheel, and uses a frequency conversion gear motor as the concentration wheel Using benzene, toluene, xylene solvents and nitrogen cylinders to complete the simulation of exhaust gas from paint exhaust workshops such as car spray painting and wind power blade baking paint, to investigate the concentration effect of the self-made new runner. At that time, the company undertook the exhaust gas treatment project of a wind power blade painting room in Tianjin, and combined with the project to do this test. Take the test results of toluene as an example: the test process investigated the removal rate of toluene tail gas under different concentration ratios and different rotor speeds.

Embodiment 2

[0043] A new type of enrichment runner uses self-developed sulfonated polypropylene fiber material to make the main part of the runner, uses plexiglass to make the support of the device, functional partitions and protective materials for the main body of the runner, and uses a frequency conversion gear motor as the concentrate runner Using methanol, ethanol, light hydrocarbon solvents and nitrogen cylinders to complete the simulation of exhaust emissions from chemical plants, raw materials, oil refining and other workshops to investigate the concentration effect of the self-made new runner. At that time, the company undertook the tail gas treatment project of a chemical and pharmaceutical company in Linyi, Shandong, and combined with the project to do this test. Take the test results of methanol as an example: the test process also investigated the removal rate of toluene tail gas under different concentration ratios and different rotor speeds. Concrete test plan is the same a...

Embodiment 3

[0052] A new type of enrichment runner adopts self-developed aminated polytetrafluoroethylene fiber material to make the main part of the runner, uses plexiglass to make the support of the device, functional partitions and the protection material of the runner main body, and uses a frequency conversion gear motor as the The driving equipment of the enrichment runner uses methyl mercaptan, ethanethiol reagents and nitrogen cylinders to complete the simulation of odorous exhaust emissions from chemical plants, raw materials and other workshops to investigate the concentration effect of the self-made new runner. At that time, the company undertook the odorous tail gas treatment project of a three-waste treatment enterprise in Tianjin Refining and Chemical Co., Ltd., and combined with the project to do this test. Take the test results of methyl mercaptan as an example: the test process also investigated the removal rate of toluene tail gas under different concentration ratios and d...

Abstract

The invention discloses a development of a novel concentrated turning wheel and application thereof in treatment of VOCs, in particular in the aspects of concentration, recycling, smell removal, odor removal, environment treatment and the like of industrial waste gas VOCs. The VOCs concentrated turning wheel is divided into an adsorption area, a regeneration area and a cooling area, the whole concentration device continuously runs in all the areas to form a turning wheel device. By adopting the concentration and purification device, low-concentration and large-volume organic waste gas VOCs can be conveniently concentrated by 5-15 times, so as to facilitate the further purification treatment of the follow-up procedures. The size of the organic VOCs waste gas purification treatment equipment can be greatly reduced, the purchase cost and running cost of the organic waste gas purification equipment can also be greatly lowered, and the purification efficiency is also doubled. The steps are simple, the operation is convenient and the practicability isstrong.

Description

technical field [0001] The invention belongs to the field of VOCs waste treatment, and in particular relates to the development of a novel concentration runner and its application in VOCs treatment. Background technique [0002] In the current era of industrialized production, the emission of VOCs from industrial sources is one of the main sources of pollution related to the national economy and the people's livelihood, such as environmental degradation, smog weather, and excessive PM2.5 particles. However, the discharge of industrial waste gas mostly presents the characteristics of large air volume and low concentration, which poses the primary problem for the subsequent waste gas treatment process: how to quickly and efficiently concentrate these exhaust gases? Domestically, the activated carbon adsorption method is mostly used in this field, and several activated carbon adsorption beds are usually operated in parallel, which requires huge equipment and occupies a large ar...
