Volatile solvent condensing and recycling device

Abstract

The invention discloses a volatile solvent condensing and recycling device. The volatile solvent condensing and recycling device comprises an evaporator, a pipeline, an induced draft fan and a condensing tank, wherein the interior of the evaporator is provided with a cavity for placing a solvent; the condensing tank is internally provided with a plurality of slantly arranged partition plates, thelower ends of the partition plates are fixed with the side wall of one end of the condensing tank, communicating cavities are formed by the higher ends of the partition plates and the side wall of theother end of the condensing tank, and the partition plates are arranged on two opposite side walls inside the condensing tank at intervals; the partition plates are used for dividing the condensing tank into a plurality of cavities, the cavities are communicated through the communicating cavities, and collecting pipes communicating with the cavities are arranged at the positions, corresponding tothe lower ends of the partition plates, outside the condensing tank; each cavity is internally provided with a plurality of condensing pipes at uniform intervals, the quantity of the condensing pipesinside the cavities from top to bottom is gradually increased, an exhaust pipe is arranged at the bottom of the condensing tank, and the exhaust pipe is internally provided with an adsorption filterlayer. Compared with the prior art, according to the device, the recycling efficiency of a volatile solvent is greatly improved, the environmental pollution is reduced in the process, and the purity of each separated component is relatively high.

Description

technical field [0001] The invention belongs to the technical field of solvent recovery, and specifically discloses a volatile solvent condensation recovery device. Background technique [0002] In the process of surface hydrophobic modification of water-absorbing materials, equipment is generally used to graft or coat one or more layers of hydrophobic groups or organic substances on the inner and outer surfaces of the matrix material through chemical reactions. These hydrophobic groups or organic substances Before reacting to the surface of the matrix material, one or more volatile solvents need to be added for the purpose of dissolution and dilution, so as to improve the reaction efficiency and quality. In the above process, the volatile solvent is only a consumable in the reaction process. After the above reaction is completed, the volatile solvent needs to be recovered for reuse. Otherwise, the volatilized organic solvent will cause serious environmental pollution and s...
