High-concentration-ratio high-temperature-resistant light-weight organic waste gas concentration device and method

Abstract

The invention relates to volatile organic waste gas control equipment, and aims at providing a high-concentration-ratio high-temperature-resistant light-weight organic waste gas concentration device and method. A hollow casing of the device is separated into an upper part adsorption cavity and a lower part exhaust gas collecting cavity by a transverse separation plate; the adsorption cavity and the exhaust gas collecting cavity do not communicate with each other; a core body combination body of a round tubular structure formed by a plurality of adsorption blocks is arranged in the casing; a desorption cavity is jointly formed by the outer wall of each core body combination body and a vertical separation plate; the vertical separation plate is arranged in a core body passage; the core bodypassage is separated into an exhaust gas passage and a concentrated waste gas passage; the separation plates are both in fixed arrangement and are in elastic sealed contact with the surface of the core body combination body; the free rotation of the core body combination body is maintained; meanwhile, the gas at the two sides can be blocked; the mutual circulation is avoided. The quantity of the core body combination body can be increased according to the designed desorption capability requirements; the device modification flexibility is improved; the adsorption capability of the adsorption blocks after the desorption is ensured at the lowest cost; the effective use service life of the adsorption block can be greatly prolonged.

Description

technical field [0001] The invention relates to the field of volatile organic waste gas treatment, in particular to a high-concentration-ratio high-temperature-resistant light-duty organic waste gas concentration device and method. Background technique [0002] With the progress of our country's social economy, air pollution is becoming more and more serious. In order to meet the people's growing needs for a better life, relevant national departments have issued a series of environmental protection policies, and various localities have successively implemented comprehensive control projects for volatile organic compounds in key areas and key enterprises. Among them, focusing on petrochemical, chemical, coating, packaging and printing industries, the implementation of whole-process prevention and control measures for volatile organic compounds. New, rebuilt and expanded projects that emit volatile organic compounds must be constructed in accordance with the principles of "fi...

AI Technical Summary

Problems solved by technology

Due to the poor flexibility of its single adsorption cylinder structure and the disadvantages of activated carbon itself, as the diameter of the cylindrical structure increases, the loss when filling the adsorption material increases, and the gas flow tends to be turbulent, which is not conducive to improving the adsorption and purification efficiency. ; The weight of the adsorption cylinder has increased significantly, the driving load has gradually increased, and the energy consumption has increased, which limits the application

In addition, the technical solution also has problems such as that the adsorption material cannot be cooled to ensure the adsorption capacity after desorption when the high-temperature desorption gas is used, and the desorption gas channel is set inside the cylindrical structure, which makes it impossible to meet the needs of increasing desorption treatment objects.
