Problems solved by technology

[0002] Exhaust gas treatment and waste organic solvent recovery are usually required in the coating workshop. At present, the "RTO" heating method of the exhaust gas treatment facility in the coating workshop uses natural gas combustion and electric heating, and the operating cost is relatively high; while the waste organic solvent is recovered only as a new Organic solvents are used, resulting in low utilization of waste organic solvents

Abstract

The invention discloses a waste organic solvent recycling device which comprises a solvent recycling device, a pressurizing atomization device, a power system and an RTO, wherein a solvent liquid outlet end of the solvent recycling device is communicated with the pressurizing atomization device, and the pressurizing atomization device is communicated with a combustion chamber of the RTO through the power system. By the adoption of the waste organic solvent recycling device, a regenerated solvent is used as fuel to replace natural gas after a series of treatments are carried out on the regenerated solvent, so that the operation cost is greatly reduced, the regenerated solvent is recycled, the utilization rate of the regenerated solvent is improved, and the effects of energy conservation andemission reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a waste organic solvent recovery and reuse device. Background technique [0002] Exhaust gas treatment and waste organic solvent recovery are usually required in the coating workshop. At present, the "RTO" heating method of the exhaust gas treatment facility in the coating workshop uses natural gas combustion and electric heating, and the operating cost is relatively high; while the waste organic solvent is recovered only as a new Organic solvents are used, resulting in low utilization of waste organic solvents. Contents of the invention [0003] In order to solve the problems existing in the prior art, the object of the present invention is to provide a waste organic solvent recovery and reuse device, after a series of treatments on the regenerated solvent, the regenerated solvent can be used as fuel instead of natural gas, and the operating cost can...
