Product Introduction:

Activated alumina is a white spherical porous particle with uniform particle size, smooth surface, high mechanical strength, strong moisture absorption, no swelling or cracking after water absorption, non-toxic, odorless, and insoluble in water and ethanol. It has many capillary channels, a large specific surface area, and can be used as an adsorbent, desiccant, and catalyst. At the same time, it is determined based on the polarity of the adsorbed substance, which has strong affinity for water, oxides, acetic acid, alkali, etc. It is a micro water deep desiccant and an adsorbent for adsorbing polar molecules.

Activated alumina for fluoride removal is similar to anion exchange resins, but anion resins have greater selectivity for fluoride ions. Activated alumina has good adsorption defluorination effect and stable capacity. This product has high strength, low wear, does not soften when immersed in water, does not expand, does not pulverize, and does not crack. It can be widely used for deep drying and hydrogen production of petroleum cracking gas, ethylene propylene gas, air separation units, drying of instrument air dryers, and fluoride treatment in hydrogen peroxide. It can also remove pollutants such as sulfur gas, hydrogen, sulfur dioxide, hydrogen fluoride, and hydrocarbons from exhaust gas, especially suitable for defluorination treatment of fluorine-containing water.

What is the function of the pre filter of the adsorption dryer?

Answer: The pre filter of the adsorption dryer is used to remove solid and liquid pollutants from compressed air, extending the service life of the desiccant layer (especially oil pollution can cause the desiccant to become ineffective due to "poisoning").

What is the purpose of increasing the adsorption bed of the adsorption dryer?

Answer: 1. Increase the contact time between compressed air and adsorbent;

2. Additional adsorbents are used to compensate for the natural aging of desiccants:

3. Ensure stable dew point temperature at the outlet;

4. Save enough adsorption heat for normal regeneration needs.

Why can't the regeneration tower pressure of the adsorption dryer be reduced to below 2kgf/cm2?

Answer: 1. The muffler is blocked;

2. One way valve malfunction;

3. The exhaust valve has been open for too long;

4. The regeneration/boost valve cannot be opened

What is the reason why the power indicator light of the adsorption dryer does not light up. How to solve it?

Answer: 1. The power is not connected. Check the voltage on the circuit terminal board.

2. Place the switch in the off position. Place the switch in the open position.

3. The switch is malfunctioning. Replace the switch.

4. The indicator light has been burned out. Replace the indicator light.
