The invention discloses a water curtain type paint spray booth gas-liquid circulation system and a control method thereof. A gas path system comprises a gas-water separator, an exhaust fan, a first filter, a circulation air valve, a gas mixer, a fresh air valve, an air conditioner, a second filter and a circulation air flow valve; a liquid path system comprises a circulation water pump, a new water valve, a circulation water valve, a liquid mixer, a wastewater discharge pump and a wastewater flow valve; and gas paths of a paint spray booth and a drying room are cascaded, gas is introduced intonew air replacement after being circulated for multiple times in the gas path system, and through two-stage filter treatment and temperature and humidity adjustment of the air conditioner, the air cleanliness and temperature-humidity requirements of the paint spray booth and the drying room can be ensured. In the liquid path system, cleaning water at the bottom of the paint spray booth is circulated, the water amount is reduced, polluted water with paint dregs is discharged through the wastewater discharge pump, water is replenished through a new water source, and thus water supply requirements of water curtain purification can be met.
Description
technical field [0001] The invention relates to spraying technology, in particular to a water curtain type paint spraying room air and liquid circulation system and a control method thereof. Background technique [0002] In the field of industrial painting (such as the painting of automobile bodies, auto parts, household appliances, etc.), painting operations must be carried out in a clean environment equipped with air-conditioning and air supply devices, usually with a dedicated spray booth. In order to reduce the dispersion of paint mist, wet spray booths with water curtain devices have been well applied. [0003] According to the requirements of the spraying environment, the temperature and humidity in the spraying room need to be kept within a certain range, and the air and liquid in the room must have a certain fluidity. Recycling, equipment energy consumption is high, environmental pollution is serious, and it is difficult to meet the needs of energy saving and emissi...
