Description

Horizontal tank reactor for loading granular activated carbon

Technical Field

The utility model relates to the technical field, specifically a horizontal tank body reactor for loading granular activated carbon.

Background

The volatile organic compound is an organic compound having a saturated vapor pressure of 0.13kPa or higher at 20 ℃. The method mainly comes from the emission of waste gas in the petrochemical industry, the volatilization of oil products such as oil reservoirs, gas stations and vehicles, and the use of organic solvents in industries such as paint, coating, packaging, printing, adhesive and cosmetics. VOCs are mostly toxic, and can be volatilized into air in a natural state due to high saturated vapor pressure and enter a human body through a respiratory tract to induce various diseases. VOCs are also one of the pioneers in haze weather, and particulate matter produced by chemical conversion of VOCs may account for 21% of PM2.5 sources in some regions. The secondary aerogel formed by VOCs through photochemical reaction accounts for 25% -35% of PM10, and is an important component of PM 10. With the continuous appearance of large-scale haze weather, the problem of VOCs treatment has attracted high attention of all countries in the world, and if VOCs, especially VOCs with high concentration and high value, can be economically and effectively recovered, the method has triple benefits of environment, health and economy. The active carbon adsorption recovery process is suitable for purifying waste gas in petrochemical industry, pharmaceutical chemical industry, pesticide chemical industry, coating industry, printing industry, tanning industry, superfine fiber (artificial leather), ultra-high molecular weight polyethylene fiber (PE fiber) and other industries.

The adsorption method is the most common method for treating VOCs at present, and is particularly suitable for treating VOCs with low concentration. Compared with other VOCs treatment technologies, the adsorption method can selectively separate mixtures which are difficult to separate in other processes, has high removal efficiency on low-concentration toxic and harmful substances, is simple, convenient and safe to operate, does not have secondary pollution, and can achieve the purposes of organic solvent recovery and adsorbent recycling after treatment. The currently used adsorbents include activated carbon, silica gel, activated alumina and zeolite molecular sieves. In recent years, methods for treating VOCs with activated carbon fibers, activated carbon nanotubes, carbide-derived carbon, activated carbon cloth, and the like have also attracted attention. Activated carbon has several advantages over other adsorbents: the adsorbent has wide pore size distribution, developed micropores and quick adsorption process, can adsorb substances with different molecular sizes, is very effective in adsorbing and recovering VOCs (volatile organic compounds) such as benzene, ethyl acetate, chloroform and the like, and has nonpolar and hydrophobic surface characteristics, so that the adsorbent has good selectivity on the adsorption of nonpolar substances; the activated carbon is cheap and sufficient in raw materials, simple in preparation process and easy to desorb and regenerate, and on the basis, the activated carbon is widely used as an adsorbent to treat VOCs with low concentration and large air volume and medium relative molecular mass (generally about 45-130), especially wood particle activated carbon prepared by a phosphoric acid method, has the advantages of large adsorption capacity, small desorption residue, rich surface functional groups, economic and environment-friendly preparation process and the like, and is widely used for treating the VOCs at home and abroad.

The structure is provided with a movable active carbon support frame which slides out of the shell of the adsorption box, so that the active carbon adsorption layer is convenient to replace.
