Electrostatic spray booth with purification function

Abstract

The invention relates to an electrostatic spray booth with a purification function. The electrostatic spray booth comprises a electrostatic spray booth body, wherein an electrostatic spray head is mounted in the electrostatic spray booth body, a main water curtain plate and a side water curtain plate are arranged on inner walls of the electrostatic spray booth body, the back side of the main water curtain plate of the electrostatic spray booth body is connected with a vapor-water separation chamber, a slope flushing plate is arranged at the lower part of the main water curtain plate, the electrostatic spray booth body is communicated with the vapor-water separation chamber through a dual-atomized paint mist catching structure connected with the lower end of the slope flushing plate, a bottom plate guide structure is arranged on the bottom surface of the electrostatic spray booth body, and the vapor-water separation chamber is connected with a slag removal chamber through a pipeline. The electrostatic spray booth is simple in structure, scientific and reasonable in design, low in cost and high in paint mist catching efficiency.

Description

Technical field [0001] The invention belongs to the field of paint spray booths, in particular to an electrostatic spray booth with purification function. Background technique [0002] Electrostatic spraying is a spraying method that uses a high-voltage electrostatic electric field to make negatively charged paint particles move in the opposite direction of the electric field and adsorb the paint particles on the surface of the workpiece. In order to achieve environmental protection requirements, the prior art electrostatic spray booths spray paint The room will use liquid chemical water to capture the excess spray paint to achieve the separation of VOC and paint mist, so as to carry out effective environmental protection treatment respectively. The existing spray booth is mainly used to capture the paint mist structure through the vertical water curtain board. A water curtain is formed on the surface of the water curtain to capture the excess paint mist from the spray paint, but...

Problems solved by technology

[0002] Electrostatic spraying is a spraying method that uses a high-voltage electrostatic electric field to make negatively charged paint particles move in the direction opposite to the electric field, and adsorb the paint particles on the surface of the workpiece. In the room, the excess spray paint will be captured by liquid agent water to separate VOC and paint mist, so as to carry out effective environmental protection treatment respectively. A water curtain is formed on the surface of the water curtain to capture the excess paint mist from spraying, but the structure has limited capture capacity and a low capture rate. The reason is that the surface area of ​​the water curtain is small, and the capture rate is relatively low on the limited water curtain. Low, because the paint mist is carried out by the gas, so the load in the subsequent environmental protection treatment of organic waste gas is relatively large
