Spraying water recycling device for water-curtain spray booth

Abstract

The invention discloses a spraying water recycling device for a water-curtain spray booth. A tank used for filtering and recovering is mounted at the bottom end of the spray booth and connected with a water collection tank in the spray booth through a spraying water inflow pipe. A control valve used for allowing spraying water to flow and cutting off the spraying water and a detachable rough screen capable of filtering out large paint blocks in the spraying water are additionally arranged at the junction of the spraying water inflow pipe and the tank. A recovered water outlet pipe provided with a detachable fine screen is connected to the bottom end of the tank. The detachable fine screen on the recovered water outlet pipe can filter out small paint blocks in the spraying water, and thus the spraying water is further purified. The purified spraying water flows out directly through the recovered water outlet pipe. The filtering and recovering tank is further wrapped with a layer of copper-indium-gallium-selenium flexible thin-film solar cells. The spraying water recycling device is simple in structure, convenient and fast to operate, and practical; and the spraying water recycling device is wrapped with the layer of CIGS flexible thin-film solar cells, and utilization of energy resources is optimized through the flexible thin-film solar energy technology.

Description

technical field [0001] The invention relates to an improved device for a water curtain spray booth, in particular to a spray water recycling device for a water curtain spray booth. Background technique [0002] In the general environment where the whole people advocate energy saving and environmental protection, the recycling and reuse of spray water has become the primary environmental protection problem faced by the spray paint industry. Due to the high pollution value of spray water, it is difficult to degrade and must be treated accordingly before it can be reused or emission. At present, the commonly used treatment method is to add flocculant to the spray water to collect the fine paint mist into paint blocks, but the spray water treated by this method is not conducive to recycling and reuse, and the water tank needs to be cleaned regularly, which is costly Manpower and material resources increase unnecessary production costs. Contents of the invention [0003] The ...
