Problems solved by technology
[0003] In the volatile organic waste gas purification and recovery device in the related art, the analysis tower and the adsorption tower are separately set up, which wastes space and cost
At the same time, in the related technology, the volatile organic waste gas is not pretreated, so the solid particles in the volatile organic waste gas enter the absorption solvent and circulate continuously in the absorption tower and the desorption tower, which is easy to cause pipelines and spraying devices blockage, and precipitate or scale in the desorption tower and the adsorption tower, affecting the purification effect

Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0018] see figure 1 , is a schematic structural view of the volatile organic waste gas purification system of the present invention. The volatile organic waste gas purification system 1 includes a pretreatment device 11 , an absorption and desorption device 12 , a recovery device 13 , a vacuum device 14 , a vent 15 and a flame arrester 16 .
[0019] The pretreatment device 11 , the absorption and desorption device 12 and the recovery device 13 are arranged in sequence along the air intake direction. After the volatile organic waste gas is pretreated by the pretreatment device 11, the absorption and vacuum desorption of the volatile organic waste gas are carried out in the absorption and desorption device 12, and the desorption gas enters the recovery device 13 for recycling, recycling Tail gas enters the absorption and desorption device 12 for reabsor...

The invention provides a purifying system for volatile organic exhaust gas. The purifying system for volatile organic exhaust gas comprises a vacuum-pumping apparatus and a pretreatment apparatus, an absorption-desorption apparatus and a recovery apparatus successively arranged along an air inflow direction, wherein the pretreatment apparatus comprises a nanometer adsorption part and a pre-absorption part; the absorption-desorption apparatus comprises an absorption part, a desorption part and a cycling device; the absorption part, the cycling device and the desorption part are communicated and form a volatile organic exhaust gas absorption-desorption circulation loop; and the desorption part, the vacuum-pumping apparatus, the recovery apparatus and the absorption part are communicated and form a desorbed gas recovery and re-absorption circulation loop. Compared with the prior art, the purifying system for volatile organic exhaust gas provided by the invention has the following advantages: the absorption part and the desorption part of the purifying system are integrally arranged, so space and cost are saved; and the purifying system carries out nanometer adsorption and preadsorption treatment on volatile organic exhaust gas so as to prevent the system from damage by solid impurities and improve adsorption effect.
Description
technical field [0001] The invention relates to the technical field of environmental protection, in particular to a volatile organic waste gas purification system. Background technique [0002] With the continuous development of science and technology, the continuous progress of society, people's living standards are also constantly improving. While people are improving and improving their living standards, their requirements for environmental protection are also increasing. At present, some living enterprises with pollution sources, such as: chemical industry, mining industry, etc., have also successively developed a variety of related volatile organic waste gas and waste liquid purification and recovery technologies. [0003] In the volatile organic waste gas purification and recovery device in the related art, the analysis tower and the adsorption tower are separately installed, which wastes space and cost. At the same time, in the related technology, the volatile organ...
