Problems solved by technology

[0004] There are many existing adsorbent recovery technologies, such as steam desorption and condensation technology, but waste water will be generated during the recovery process, causing secondary pollution; hot air desorption-combustion technology is less safe during the recovery process, and activated carbon is prone to occur Spontaneous combustion phenomenon; hot nitrogen desorption-condensation / catalytic combustion technology has high operating costs, and the desorption efficiency is not ideal, and the desorption rate is slow

Embodiment Construction

[0026] like figure 1 As shown, a kind of adsorbent recycling system of the present invention comprises a vacuum desorption tower 10, a vacuum pump 20, a dust removal mixing air box 30, a catalytic combustion fan 40, a catalytic combustion furnace 50, a diluted fresh air inlet 60, a row of Air cylinder 70 and a valve assembly 80 . The top of the vacuum desorption tower 10 has a feed port 11, and the bottom has a discharge port 12. The adsorbent is inserted into the vacuum desorption tower 10 through the feed port 11, and is passed through the discharge port 12. It is taken out from the inside of the vacuum desorption tower 10. The vacuum pump 20 has a vacuum pump air inlet and a vacuum pump air outlet, and the top of the vacuum desorption tower 10 also has an exhaust port 14, and the exhaust port 14 is connected with the vacuum pump air inlet through a pipeline; The air mixing box 30 has a dust removal mixing air box air inlet and a dust removal mixing air box air outlet, and...

Abstract

The invention discloses a system for recovering and using an adsorbent. The system comprises a vacuum desorption tower, a vacuum pump, a dedusting and wind-mixing box, a catalytic combustion fan and acatalytic combustion furnace which are sequentially connected by a pipeline, an adsorbent is placed in the vacuum desorption tower, organic matters adsorbed to the surface of the adsorbent are decomposed under the co-action of the vacuum desorption tower, the vacuum pump, the dedusting and wind-mixing box, the catalytic combustion fan and the catalytic combustion furnace and finally generate CO2and H2O, and the CO2 and H2O are discharged, so the recovery process is safe and efficient, and no secondary pollution is generated. The invention discloses a technology for recovering and using the adsorbent. The safe and efficient recovery of the adsorbent can be achieved through controlling the working states of the vacuum desorption tower, the vacuum pump, the catalytic combustion fan and thecatalytic combustion furnace by adopting the system for recovering and using the adsorbent.

Description

technical field [0001] The invention relates to the technical field of adsorbent recovery, and more precisely relates to an adsorbent recovery and utilization system and process. Background technique [0002] With the continuous development of our country's economy and the deep adjustment of industrial structure, cleaner production has become a development concept deeply rooted in the hearts of the people. We have seen that in recent years, our country has continuously increased the intensity of environmental remediation and investment, especially industrial waste gas, and has achieved remarkable results. There are many options for exhaust gas treatment, but due to the influence of comprehensive factors such as investment and operation costs and production status, some enterprises choose to use adsorption method to deal with the exhaust gas generated in the production process. Adsorption treatment of waste gas has the advantages of low investment cost, simple and mature pro...
