Problems solved by technology

[0003] The problem to be solved by the present invention is to provide a granular activated carbon adsorption process, which solves the problem that after the steam heating desorption process is used alone for desorption, the adsorption effect of the adsorbent is very good, and the gas after adsorption can be discharged up to the standard, but the consumption of steam Larger, higher economic operation cost; or after desorption by vacuum decompression desorption process alone, the effect of adsorbent re-adsorption is not very good, the gas after adsorption cannot be discharged up to the standard, and the power consumption is large, economical operation The cost is also high, which cannot meet the needs of manufacturers

Abstract

A granular activated carbon adsorption process provided by the invention, wherein the process includes nitrogen replacement stage, pretreatment stage, adsorption stage, desorption stage, recovery stage, and the device includes nitrogen, organic waste gas pretreatment device, water vapor, adsorber and condensation The device has a simple structure and a reasonable design. Combining the vacuum decompression desorption technology with the steam heating desorption technology is more conducive to the adsorption and treatment of waste gas containing organic components, so as to achieve the purpose of emission reduction and emission compliance, and reduce the regeneration of adsorption materials. At the same time, it can greatly reduce the consumption of steam, greatly reduce the total energy consumption, and solve the practical problem of high total cost of economic operation. At the same time, the investment cost is low, which can better meet the actual needs of manufacturers. On the other hand, the The collected oil and water can be recycled to achieve the purpose of energy saving.

Description

technical field [0001] The invention relates to the technical field of granular activated zeolite adsorption, in particular to a granular activated carbon adsorption process. Background technique [0002] At present, most of the organic waste gas treatment processes of granular activated carbon adsorption method are: first, the organic waste gas is pretreated, pressure adjusted, and temperature adjusted, and then adsorbed by the adsorber, steam heating and desorption (or vacuum decompression desorption), and the desorption is carried out. The oil gas is condensed into a liquid mixture (or liquid oil) by the condenser and recovered, and the clean gas after adsorption is discharged at high altitude, so as to achieve the purpose of emission reduction and emission compliance. This type of process mainly includes two desorption processes, one is water vapor heating desorption, and the other is vacuum decompression desorption. If the steam heating desorption process is used alone...
