Example Embodiment

[0039] Such as figure 1 As shown, the petroleum solvent recovery device of the dryer includes a dryer 100 and a recovery mechanism 200. The dryer 100 has washing and drying functions. The dryer 100 communicates with the recovery mechanism 200 through a channel 100a. The gas with petroleum solvent formed during the drying process of the dryer 100 is sent to the recovery mechanism 200 through the channel 100a, and the petroleum solvent is recovered by the recovery mechanism 200 for use. In addition, the recovery mechanism 200 is also connected to the recovery mechanism 200 through the channel 200a. The dryer 100 is connected, and the recovered petroleum solvent can be sent to the dryer 100 through the channel 200a for recycling through the control valve. It reduces the consumption of the petroleum solvent of the dryer, saves the use cost, and at the same time greatly reduces the emission of the petroleum solvent of the dryer, and to a large extent avoids the direct pollution of th...

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...
