技术领域 technical field
本实用新型涉及一种干燥机，特别涉及一种热回收组合式干燥机。The utility model relates to a dryer, in particular to a heat recovery combined dryer.
背景技术 Background technique
压缩空气广泛应用于公路隧道、石油管道、化工、矿山、钢铁等行业的野外或非固定工作场所的施工。由于空压机排出的是一种低品质的劣质气体，含有大量的水蒸气，灰尘，油污不能满足对气体品质要求较高的需求。因此需要对压缩空气进行净化、干燥处理。现有的干燥机主要包括吸附式干燥机、气冷式冷冻干燥机及组合式干燥机。现有的组合式干燥机由冷冻式干燥机和吸附式干燥机所组成，冷冻式干燥机中出来的压缩气体出来后从吸附式干燥机的下方进入吸附塔，从冷冻式干燥机中出来的再生气体从吸附式干燥机的上方进入再生塔。此种结构的组合式干燥机，一方面，由于压缩气体从冷冻式干燥机出来后从吸附式干燥机的下方进入吸附塔，这样会对干燥剂造成翻滚，磨损干燥剂，降低干燥剂的寿命，且还会造成后方成品气出现粉尘，影响空气品质；另一方面，由于再生气体从冷冻式干燥机中出来后从吸附式干燥机上方进入再生塔，这样无法完全将干燥剂充分再生，造成下次空气要干燥时，空气品质达不到预期。Compressed air is widely used in the construction of road tunnels, petroleum pipelines, chemical, mining, steel and other industries in the field or in non-fixed workplaces. Because the air compressor discharges a low-quality and inferior gas, which contains a large amount of water vapor, dust, and oil, it cannot meet the high requirements for gas quality. Therefore, it is necessary to purify and dry the compressed air. Existing dryers mainly include adsorption dryers, air-cooled freeze dryers and combined dryers. The existing combined dryer is composed of a freeze dryer and an adsorption dryer. The compressed gas coming out of the freeze dryer enters the adsorption tower from the bottom of the adsorption dryer, and the compressed gas coming out of the freeze dryer The regeneration gas enters the regeneration tower from above the adsorption dryer. The combined dryer with this structure, on the one hand, because the compressed gas enters the adsorption tower from the bottom of the adsorption dryer after coming out of the freeze dryer, it will cause the desiccant to roll, wear the desiccant, and reduce the life of the desiccant. , and it will also cause dust in the rear product gas, which will affect the air quality; on the other hand, since the regeneration gas comes out of the refrigerated dryer and enters the regeneration tower from the top of the adsorption dryer, the desiccant cannot be fully regenerated, resulting in The next time the air is going to be dry, the air quality is not as expected.
