Description

TECHNICAL FIELD

[0001] The present application relates to an oil curtain spraying room oil and gas separation device, belonging to the technical field of spraying equipment. BACKGROUND

[0002] The paint spraying room is a room for spraying paint on the spraying object. The paint spraying room is a device for providing a special environment for coating operation, which can meet the requirements of temperature, humidity, illuminance, air cleanliness and other requirements of coating operation, can limit and treat the paint mist and organic waste gas generated during the spraying operation and then discharge, and is an environmentally friendly coating device.

[0003] The currently widely used paint spraying room mainly includes dry paint spraying room and wet paint spraying room: the dry paint spraying room generally uses a filter screen and low-quality filter material to filter paint mist, which needs to be checked and replaced regularly, otherwise it may cause fire. With the further development of science and technology, the way to handle excess paint mist is becoming more and more advanced. Many high-end cars use water treatment paint spraying room to dissolve excess paint mist in water, which has made great progress in the way of treating paint mist.

[0004] Most of the current paint spraying rooms are water washing type spraying rooms, the main reason is that the water washing type spraying room has high equipment efficiency, generally up to 95%-98%; has low risk of fire; and has high safety. However, the water washing type spraying room has the following disadvantages:

[0005] 1. A large amount of waste water is generated during use, polluting the environment;

[0006] 2. A large amount of chemical agents need to be added to realize the chemical separation of the waste paint residue adsorbed in water and the circulating water, and a paint residue separation device is needed to realize the physical separation of the circulating water and the waste paint residue, which has a large amount of work and a very foul environment, greatly polluting the environment;

[0007] 3. The water washing type spraying room is prone to rust, and the circulating water needs to be replaced every six years, at which time a large amount of polluting waste water will be generated, which needs to be treated to meet environmental protection requirements before being discharged.

In the oil-gas separation chamber, the air carrying paint mist contacts the oil curtain of the left and right oil curtain plates respectively, so that the oil gas mixed with paint slag is separated from the air, and the mixture of waste paint slag and mineral oil is left in the oil storage tank. The clean air after separation is collected from the return air outlet and discharged, completing the paint mist separation process. The air after purification is sent to the environmental protection treatment equipment (RTO) for final treatment, so as to meet the standard for emission into the atmosphere. The mixture of waste paint slag and mineral oil left in the oil tank is separated into solid waste paint slag and recycled mineral oil by the paint slag treatment and recovery device. The separated mineral oil enters the circulation system and is recycled.
