Novel desorption equipment and desorption method

Abstract

The invention discloses novel desorption equipment and a desorption method, and relates to the technical field of organic waste gas treatment environmental protection, the equipment comprises a nitrogen supply device, a heating device, a heat exchange device, a desorption fan, a desorption box and a waste gas mixing box; wherein the nitrogen supply device is communicated with the desorption box through a gas pipeline; the desorption box is respectively communicated with the heat exchange device, the heating device and the waste gas mixing box through gas pipelines; the heat exchange device is also communicated with the heating device and the waste gas mixing box through gas pipelines; and the desorption fan is communicated with the heat exchanger through a gas pipeline. The desorption equipment is environmentally friendly, low in manufacturing cost, small in occupied area and easy to install; because the nitrogen serves as a desorption medium to recover organic waste gas, the problem of secondary pollution caused by water vapor desorption regeneration can be solved, the equipment has more advantages in recovery of soluble organic matter, investment and operation cost for refining of the organic matter can be reduced, and the equipment is suitable for industrial production. Meanwhile, the service lives of the activated carbon and equipment can be prolonged, and the market competitiveness is higher.

Description

technical field [0001] The invention relates to the technical field of organic waste gas treatment and environmental protection, in particular to a novel desorption equipment and a desorption method. Background technique [0002] In the prior art, in the process of organic waste gas treatment, the organic waste gas with high boiling point needs to be desorbed at a temperature above 200°C. During high temperature desorption, it is easy to burn activated carbon, and there will be The problem of secondary pollution caused by water vapor desorption and regeneration, and the effective recovery of soluble organic matter cannot be realized. In addition, the cost and operation cost of desorption equipment are high, and the service life of activated carbon and desorption equipment is not high. Contents of the invention [0003] The invention provides a novel desorption equipment and a desorption method, which solve the above technical problems. [0004] The invention provides a n...
