Double atomization capture electrostatic spray booth

Abstract

The invention relates to a double-atomization capturing electrostatic paint spray booth which comprises an electrostatic paint spray booth. An electrostatic spray nozzle is mounted in the electrostatic paint spray booth, a main water curtain plate and side water curtain plates are arranged on the inner wall of the electrostatic paint spray booth, a steam-water separation chamber is connected to the back of the main water curtain plate of the electrostatic paint spray booth, a bevel flushing plate is arranged on the lower portion of the main water curtain plate, the electrostatic paint spray booth is communicated with the steam-water separation chamber via a double-atomization paint mist capturing structure which is connected with the lower end of the bevel flushing plate, and a bottom plate flow guide structure is arranged at the bottom of the electrostatic paint spray booth. The double-atomization capturing electrostatic paint spray booth has the advantages that the double-atomization capturing electrostatic paint spray booth is simple in structure, scientific and reasonable in design, low in cost and high in paint mist capturing efficiency, and follow-up environmental protection treatment load can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of spray paint booths, in particular to a double atomization capture electrostatic paint spray booth. 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 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 carr...

[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
