Abstract

The invention discloses a solvent recovery system and a technology thereof. The solvent recovery system comprises a vacuum generator, a cooling water circulating device, a condensing recovery device, a secondary circulation condensing device, and a control system. The cooling water circulating device comprises a first heat exchanger and a second heat exchanger, and the first heat exchange and the second heat exchanger are connected in sequence through a pipeline. The first heat exchanger is arranged in the condensing recovery device, the first air inlet is connected to the vacuum generator, and the liquid outlet is connected to a receiving tank. The second heat exchanger is arranged in the secondary circulation condensing device, the second air inlet is connected to the first gas outlet of the condensing recovery device, the second air outlet is connected to the vacuum generator, and the control system is used to start or stop the solvent recovery system. The provided solvent recovery system has the advantages that the structure is safe, the recovery rate is high, the solvent consumption during the production process is reduced, the wastewater treatment can be eliminated, the energy consumption is reduced, and the conventional solvent recovery technology is improved at the same time.

Description

technical field [0001] The invention relates to the field of solvent recovery, in particular to a solvent recovery system and a process thereof. Background technique [0002] A solvent is a liquid that can dissolve gases, solids, and liquids to form a homogeneous mixture. It is an auxiliary material in the production process and plays an indispensable role in the production process. Due to the complex characteristics and variety of solvents, most companies do not pay much attention to the recovery of solvents, resulting in excessive consumption of solvents when producing the same product, and the degree of waste is far higher than the international advanced level. [0003] Nowadays, the solvent recovery work is limited by the technical level of domestic equipment, resulting in low cost performance of solvent recovery, and there is no better solution. For example, according to the characteristics of the production process, it is necessary to use a variety of small batches of ...
