Recycling device for organic solvent condensation and adsorption and desorption combination

Abstract

The invention discloses a recycling device for organic solvent condensation and adsorption and desorption combination, and relates to the technical field of organic solvent recovery. The recycling device comprises an adsorption and desorption box and a condensation box. The adsorption and desorption box includes an adsorption chamber and a desorption chamber. Supporting rods are mounted and fixedon the inner walls of the adsorption chamber and the desorption chamber. One end of each of the two supporting rods is rotatably connected with a driving roller, the other end of each of the two supporting rods is rotatably connected with a driven roller, and connecting rollers are evenly disposed on the inner sides of the two supporting rods. The plurality of connecting rollers are located between the driving roller and the driven roller, the driving roller and the driven roller are in transmission connection through a desorption belt, a fixing frame is fixed on one surface of the supportingrod, a motor is fixed on one surface of the fixing frame, the lower surface of the adsorption chamber is provided with a first air inlet, a filter screen is fixed at the position of an inlet of the first air inlet, and the first air inlet is fixedly connected with an evaporator through a pipe. According to the recycling device, adsorption and desorption are performed through an adsorption and desorption integrated structure and back-and-forth circulation of the desorption belt, so that the purity of an extracted organic solvent is higher, and an effect is better.

Description

technical field [0001] The invention belongs to the technical field of organic solvent recovery, in particular to a recovery device used for the combined use of organic solvent condensation and absorption and desorption. Background technique [0002] In the chemical production process, organic solvents are often used in the processes of dissolving, refining, and purifying chemical products, and are directly discharged into the air during vacuum drying, vacuum distillation, plasticizing molding, and suction filtration processes, causing serious Environmental pollution and waste of resources also increase potential safety hazards. With the rapid development of my country's chemical industry, the use of organic solvents is showing an increasing trend year by year. Therefore, the research on organic solvent recovery devices to improve recovery efficiency can be applied in the production of chemical industry, which has broad practical value. [0003] At present, the methods for ...
