Abstract

The invention provides a desorption device and method. The desorption device comprises a tower body and a gas lifting tower tray, the tower tray divides the internal space of the tower body into a primary spraying layer and a secondary spraying layer which are relatively independent and communicated, a plurality of gas lifting structures are arranged on the tower tray, and the device comprises a primary liquid inlet structure arranged above the gas lifting structures and a gas outlet structure arranged below the gas lifting structures. The device further comprises a communicating structure, and a secondary liquid inlet structure, a gas inlet structure and a liquid discharging structure which are arranged in order from top to bottom. according to the desorption device and method, the gas raising tower tray is additionally arranged in the device, the internal space of the device is divided into the two relatively independent and communicated spraying layers, and desorption separation operation is achieved; meanwhile, the gas lifting structure prevents liquid from entering the secondary spraying layer, so that the desorption effect is improved; in addition, the communicating structure enables the liquid to enter the secondary spraying layer again to realize multiple desorption operations. The problems that in the prior art, due to the fact that all stages of desorption operation are completed in the same space, final desorbed liquid is repeatedly polluted, and the desorption effect is reduced are solved.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a desorption device and method. Background technique [0002] With the rapid development of my country's industry, a large amount of harmful gases will inevitably be produced in industrial production. If these gases are directly discharged into the air, they will cause serious corrosion to the surrounding production equipment, testing instruments and building facilities, and pollute the atmosphere. The environment affects people's health and reduces people's quality of life. Therefore, these exhaust gases must be treated and discharged under the premise of ensuring that they do not pollute the atmosphere. The desorption device is such a device. Using it, it can Effectively remove a large amount of harmful gases produced in industrial production. [0003] The function of the desorption device is to remove the harmful gas components contained in the workin...
