Drying tunnel used for heating and dehumidifying water paint

Abstract

The invention discloses a drying tunnel used for heating and dehumidifying water paint. The drying tunnel comprises a drying tunnel frame. Round shafts are rotatably mounted at the two ends of the drying tunnel frame, and the two round shafts are wrapped with the same stainless steel wire mesh. The temperature of heated substances is increased, the compression dewatering and dehumidifying functions are achieved in the internal space of a liner of the whole drying tunnel, and heating and dehumidifying are combined, so that water is evaporated into mist rapidly, and water is extracted rapidly bymeans of the suction force of a centrifugal fan in a dehumidifier; a paint film is reserved, the paint film is heated at a certain temperature and then solidified into a film rapidly, and thus an effective paint film is formed in the surface of a product; air is heated, so that the relative moisture content of air is decreased and kept being about 25% (the higher the temperature of air is, the higher the saturated moisture content of air is), and thus more steam can be taken away when air passes through the surfaces of the dried substances; and the contact area between the heated substances and flow air is enlarged, and heat in exhausted air is fully utilized.

Description

technical field [0001] The invention relates to the technical field of water-based paint processing, in particular to a water-based paint heating and dehumidification drying tunnel. Background technique [0002] The country has gradually strengthened the implementation of environmental protection policies. Enterprises such as furniture, flooring, doors, and decorative materials use solvent-based paints (such as PU\PE\NC, etc.) for their original production processes and product surfaces during production. The surface coating of the product, air and water discharge have serious pollution, which has a bad impact on the social environment. [0003] The national self-environmental protection policy has stepped up efforts to allow these companies to completely eliminate the use of paints and related substrates with solvent-based VOC emissions exceeding the standard. Therefore, the development of water-based environmental protection paint must replace solvent-based paint, so it i...
