Description

Active carbon gas adsorption device

Technical Field

The utility model belongs to the technical field of waste gas treatment, and particularly relates to an active carbon gas adsorption device.

Background

In the process of processing cigarettes in a tobacco factory, a certain section can generate a certain amount of peculiar smell gas, and the peculiar smell gas is mainly various volatile organic matters, such as methylene dichloride, benzaldehyde, 6-methyl-5-hepten-2-one, phenylacetic acid and other peculiar smell waste gases. Such exhaust gases must be purged to the atmosphere and current tobacco factories have exhaust gas odor treatments using injection type plasma equipment, such as brands: the model of Kunming is CD/NH-WC700/IP-P15, and the principle is as follows: fresh air is purified into clean gas through the three-stage filter (a bag filter, a HEPA filter and an activated carbon filter) by the fresh air injection system, then the clean gas passes through a heater (the purpose of gas heating is to control the temperature and the humidity of the gas, so that the gas can be used for removing condensed water in equipment), and finally the clean gas reaching a certain temperature and humidity enters a low-temperature plasma high-pressure reaction box. The low-temperature plasma high-voltage reaction box comprises a high-voltage reaction source and a low-temperature plasma reaction module, wherein the high-voltage reaction source converts an input 380V power supply into 3KV high-voltage power; then, the high voltage power applied to the low temperature plasma reaction module generates a strong electric field to excite clean air flowing through the module, and active particles including high energy electrons, various ions, excited atoms, free radicals and the like are generated, and then the plasmas are rapidly injected into an adapter of the system equipment to collide with odor molecules in the exhaust gas, and oxidation reaction is carried out, so that the odor molecules are decomposed or oxidized into other substances, carbon dioxide, water and the like which are harmless to human bodies. Thereby the production waste gas can reach the discharge standard. The active carbon filter in the three-section filter is an active carbon fiber filter cylinder or an active carbon fiber cotton which is widely used at present in the breather pipe; the active carbon fiber filter cylinder or active carbon fiber cotton needs to be replaced after being used for a period of time, and the existing problems are that: the active carbon fiber filter cartridge or the active carbon fiber cotton which is currently commercially available is widely used in other waste gas treatment devices, namely, the use is directly used for absorbing and filtering polluted waste gas, but based on the principle of the injection type plasma device, the active carbon filter in the injection type plasma device is used for purifying fresh air into cleaner gas so as to lead the cleaner gas into a low-temperature plasma high-pressure reaction box, and the active carbon is used for absorbing formaldehyde, benzene, ammonia, total volatile organic matters TVOC and the like mixed in the air, but the content of the pollutants in the fresh air is very small, and the pollutants are mainly present in the polluted waste gas. Therefore, the activated carbon fiber filter cartridge or the activated carbon fiber cotton used in the device is 'large and small', and particularly the activated carbon fiber cotton has good adsorption effect, but because the amount of activated carbon powder blended on the sponge is small, the activated carbon is easy to saturate and needs to be replaced frequently, which causes the increase of daily replacement cost, and the most traditional activated carbon particles can be directly used for replacement is the cheapest scheme, because the currently marketed activated carbon particles are only 2.0 yuan/kg, and the pure activated carbon has no matrix such as fiber, sponge and the like; however, the use of activated carbon particles is currently lacking in related parts to enable the application of the activated carbon particles in the activated carbon filter, and the technical difficulties are also that: the problem of convenience in replacing daily activated carbon particles also needs to be considered.
