company news about Features of no pump spray room

In recent years, spray rooms have been commonly used in various fields, so what characteristics of spray rooms can be widely used? Take pump-free spray room as an example to explain the characteristics of pump-free spray room. Pumpless spray room is a new type of wet spray room in recent years, named after the pumpless spray room. The air in the pumpless spray room forms high-speed air flow when it passes through the narrow gap between the water surface and the vortex chamber under the suction of the fan. The high-speed air flow on the water surface takes advantage of the siphon phenomenon of the venturi tube to draw water into the air stream and atomize, thus replacing the atomization effect of the nozzle.

After the fan of the pump-free spray room is started, the air containing paint mist enters the cleaning room at a high speed of 20 ~ 30m/s under the action of pressure through a narrow gap (the contact point with the liquid surface is generally jagged). The paint mist and water in the air rotate into the cleaning room under the action of the suction plate. The paint particles with high density are collected by the water film of the suction plate under the action of centrifugal force. The remaining paint particles and water particles collide repeatedly in the cleaning chamber, condensing to form water droplets containing paint mist, falling into the cleaning chamber sink, flowing to the front of the sink deposit, and the air removing paint mist and water particles is discharged to the outside by the fan.

Pump-free spray room does not use a pump, and its water atomization is completed by the high-speed air flow when the air enters the narrow gap of the cleaning chamber. In order to obtain the high-speed air flow, the high wind pressure of the fan is required (about 1200 ~2500Pa). In addition, in order to ensure the stability of the section size of the narrow gap, the height of the water surface must be maintained. The pump-free spraying room generally must inject coagulants into the sink to ensure that the paint particles condense, so as to remove each shift and ensure the recycling of the sink. The above is the characteristics of the pump-free spray room. To sum up, the pump-free spray room has simple structure, high efficiency in processing paint mist and less water consumption.
