Silica gel regeneration adsorption tower and method thereof

Abstract

The invention relates to the field of chemical equipment, mainly relates to silica gel regeneration adsorption equipment and particularly provides a silica gel regeneration adsorption tower and a method thereof. The silica gel regeneration adsorption tower comprises a tower body, heat conducting plates, a sintering plate, a feeding distributor and a far infrared heater, wherein the tower body is filled with silica gel, and is coated with the far infrared heater; the upper part of the tower body extends out of the far infrared heater upwards; the feeding distributor is arranged at the upper part of the tower body which extends out of the far infrared heater and is close to the top end of the tower body; the uniformly distributed heat conducting plates are arranged in the tower body vertical to the bottom surface and are laminated with silica gel; a vacuum pump is also arranged at the lower part of the tower body; and a discharge hole is arranged in the lower part of the vacuum pump. According to the silica gel regeneration adsorption tower, regeneration of the silica gel in the tower is achieved, repeated taking and filling are avoided, the production cost is reduced, the silica gel is repeatedly used, silica gel adsorption oil can be recovered and the silica gel regeneration adsorption tower has considerable economic benefits, and is simple in operation, economic and environment-friendly.

Description

technical field [0001] The invention relates to the field of chemical equipment, mainly relates to silica gel regeneration adsorption equipment, and specifically provides a silica gel regeneration adsorption tower and a method thereof. Background technique [0002] As a kind of adsorbent, silica gel is widely used in petrochemical production. After the silica gel is saturated, it becomes waste silica gel, which is poisonous and harmful. How to deal with waste silica gel has become a difficult problem for many enterprises. Some enterprises use the method of direct incineration to deal with waste silica gel, because silica gel contains a large amount of combustible oily substances in petrochemical production, and there have been reports of using rotary kiln to treat waste silica gel, and the silica gel treated by rotary kiln is still Reusable, realizing the regeneration of silica gel. However, regardless of direct incineration or rotary kiln treatment, the operation process i...

Problems solved by technology

However, regardless of direct incineration or rotary kiln treatment, the operation process is not friendly to the site environment. The oily waste silica gel is taken out from the adsorption tower and then sent to the furnace hall or rotary kiln. The operation process will cause pollution and minimize air pollution. It is difficult to eliminate; secondly, it is uneconomical, because the mass ratio of oil substances adsorbed by silica gel to silica gel is basically 1:1, and this part of oil is wasted after incineration; and it is inconvenient to operate, and silica gel is repeatedly taken out and filled
