Activated Carbon Waste Gas Treatment - Adsorption Tower:

1、Overview

  XFT activated carbon adsorption tower can be highly efficient adsorption of organic waste gas, adsorption of activated carbon activated carbon, activated carbon is the first application, the use of a wide range of excellent adsorbent, with excellent adsorption capacity It is a variety of carbonaceous substances such as coal, wood, Coke, fruit and other carbonization, and then steam or chemical activation of the treatment, with a high porosity, the surface is generally in the range of 700 ~ 1500m3 / g, activated carbon used to adsorb the air in the treatment of organic solvents and odor Substance When a porous substance treats a fluid substance, a component or some of the components in the fluid are attracted to the solid surface and concentrated on the surface thereof to achieve the purpose of removing the organic substance.

  XFT activated carbon adsorption tower, the use of high-performance activated carbon adsorbent solid itself as the surface of the force, the adsorption of organic exhaust gas molecules attached to the surface of the adsorbent, to benzene, alcohol, ketone, ester, gasoline, non-methane Hydrocarbon and malodorous gases and other organic solvents such as exhaust gas adsorption, more suitable for large air volume and low concentration of waste gas treatment, suitable for electronics, chemicals, light industry, rubber, machinery, ships, automobiles, petroleum and other industries.

  XFT series of activated carbon exhaust adsorption tower is a dry exhaust gas treatment equipment. By the box and filled in the box within the adsorption unit. According to the number of adsorption units and air volume is divided into nine kinds of specifications, XFT series of activated carbon adsorption tower selection of different fillers can handle a variety of different waste gas, including three categories:
1. Acidic waste gas and acid mist (for example: NO2, H2SO4, HCL, HF, etc.)
2. Alkaline exhaust (eg NH3, etc.)
3. Organic exhaust and odor (eg benzene, phenols, alcohols, ethers, tincture rubber exhaust non-methane total hydrocarbons and malodorous gases)

2、structure

  The main body of the equipment is made of glass fiber reinforced plastic or stainless steel, according to the media to choose different resins, with anti-acid, alkali and salt corrosion, in the long-term operation of the use of conditions, no other factors oxidative corrosion. The thickness of the main structure depends on the type and handling capacity, and has sufficient reinforcement, enough to bear the structure and operation of the required load, and provide the necessary operating platform.

  XFT large adsorption tower with adsorption unit, adsorption tower installed in the core components. Standard adsorption unit size: 750 × 500 × 150mm. Each adsorbent unit can contain about 35 kg of adsorbent. Adsorption unit in the equipment box inside the drawer type installation, can be very convenient from both sides of the inspection door to remove. And check the door open easily, tightly sealed. XFT exhaust gas adsorption tower inspection door is divided into two upper and lower, you can open, separate removed.

4、Application scope

  XFT-type exhaust adsorption tower is particularly suitable for low concentrations of high air volume or high concentration of intermittent emissions of exhaust gas operating environment. The main application areas include:
Electronic equipment production, battery (battery) production, pickling operation workshop, laboratory exhaust, metallurgy, chemical plants, pharmaceutical production plants, painting workshop, rubber vulcanization workshop, mixing workshop, food and brewing, furniture production.

5、Key advantages

  1. High adsorption efficiency;
2. Low operating costs;
3. easy to maintain;

6、working principle

  Adsorption process:
Due to the presence of unbalanced and unsaturated molecular gravitational or chemical bond forces on the solid surface, when the solid surface is in contact with the gas, the gas molecules can be attracted to concentrate and remain on the solid surface. This phenomenon is called adsorption. The use of solid surface adsorption capacity, so that the exhaust gas and large surface porous solid material in contact with the pollutants in the exhaust gas is adsorbed on the solid surface, so that the gas mixture separation, to purify the purpose. Exhaust gas through the air filter to remove the small suspended particles, into the top of the adsorption tank, through the tank after the adsorption of activated carbon, remove the harmful ingredients, in line with the emission standards of purification gas, the fan out of the room.

  Desorption regeneration process:
Activated carbon adsorption for some time with a certain amount of solvent can be desorption regeneration. Regeneration with steam from the bottom of the tower into the activated carbon adsorption solvent evaporated, and then condensed into a liquid through the condenser, into the separation tube, separation and recovery of organic solvents, residue into the aeration cylinder, after aeration and discharge.
