Petroleum solvent recovery equipment for drying machine

Abstract

The invention provides petroleum solvent recovery equipment for a drying machine. The equipment comprises a dryer, a condensing device, a refrigerating device, a water-oil separator and a fuel tank; the dryers is provided with a discharge hole, and a gas containing a petroleum solvent is discharged outwards through the discharge hole; the condensing device is provided with an air inlet and an airoutlet, the air inlet is in communication with the discharge hole for introducing the gas containing the petroleum solvent, and the gas is discharged from the air outlet; the refrigerating device is in communication with the condensing device for refrigerating the interior of the condensing device to liquefy the petroleum solvent in the gas passing through the condensing device; the oil-water separator is in communication with the condensing device for collecting the liquefied petroleum solvent and separating oil and water; and the oil tank is in communication with the oil-water separator forcollecting the separated petroleum solvent. The equipment provided by the invention effectively reduces consumption of the petroleum solvent during washing, saves washing costs, and greatly reduces petroleum discharge of the dryer, thereby reducing pollution to the atmosphere caused by waste gases generated by dry cleaning of the petroleum solvent to a great extent.

Description

technical field [0001] The invention relates to the field of dryers, in particular to a petroleum solvent recovery device for dryers. Background technique [0002] Energy and environmental issues have become the focus of global attention. Petroleum, coal and natural gas have always been the main sources of fuel and organic chemical raw materials. However, with the depletion of fossil energy and the increasing environmental problems, the development of clean and renewable energy has become a current pressing issues. [0003] Among them, petroleum solvent can dissolve, dilute, wash and extract some substances, so it is widely used, especially in the dry cleaning industry. The currently used dryers only have a drying function. In this way, during the drying process, the petroleum solvent will be discharged directly to the outside of the dryer along with the gas. These petroleum solvents cannot be recycled and can only be wasted. The consumption of petroleum solvent is increas...

AI Technical Summary

Problems solved by technology

The currently used dryers only have a drying function. In this way, during the drying process, the petroleum solvent will be discharged directly to the outside of the dryer along with the gas. These petroleum solvents cannot be recycled and can only be wasted, which greatly Increased consumption of petroleum solvents, thus greatly increasing washing costs and polluting the environment
