Activated carbon adsorption and desorption process

Abstract

The invention discloses an activated carbon adsorption and desorption process. The activated carbon adsorption and desorption process is characterized by utilizing an activated carbon adsorption and RCO desorption process, the problems that an existing activated carbon adsorption and desorption process is high in energy consumption and ignition risk, and the service life of activated carbon is short are well solved. According to the activated carbon adsorption and desorption process, a flow field of waste gas in an adsorption bed in an activated carbon adsorption tank is uniform, the flow speed is reasonably designed, and heat generated in the process that organic matters in the waste gas are changed from a gas state into a liquid stage during adsorption can be timely dissipated, so that the danger caused due to the heating of the activated carbon bed along the continuous accumulation of phase change heat of the organic matters adsorbed by activated carbon is avoided.

Description

technical field [0001] The invention relates to the treatment of industrial organic waste gas, in particular to an activated carbon adsorption and desorption process. Background technique [0002] At present, some activated carbon adsorption and desorption processes popular on the market use TO / CO furnace as the oxidation device, which results in high energy consumption due to the large temperature difference between the inlet and outlet. In the prior art adsorption-desorption process, the desorbed hot gas flow is supplemented with a large amount of fresh air to lower the temperature to a suitable desorption temperature, and bringing in fresh air brings in a large amount of oxygen, so it is easy to catch fire. There is also the poor control of air distribution and cooling in the process. Therefore, a new process using activated carbon adsorption and RCO desorption was invented. This process solves the problems of high energy consumption, high fire risk and short service lif...

AI Technical Summary

Problems solved by technology

[0002] At present, some activated carbon adsorption and desorption processes popular on the market use TO / CO furnace as the oxidation device. Due to the large temperature difference between the inlet and outlet, the energy consumption is high.

In the adsorption-desorption process of the prior art, the desorbed hot air flow is supplemented with a large amount of fresh air to reduce the temperature to a suitable desorption temperature, and bringing in a large amount of oxygen will bring in a large amount of fresh air, so it is easy to catch fire

There is also the problem of poor control of air distribution and cooling in the process

Therefore, a new process using activated carbon adsorption and RCO desorption was invented, which solved the problems of high energy consumption, high fire risk and short service life of activated carbon in the existing activated carbon adsorption and desorption process.
