Abstract

The invention discloses recovery equipment of waste gases produced in coating. The recovery equipment comprises a primary spraying tower, a secondary solid-liquid reaction device, a secondary sprayingtower and a solid-liquid reaction device, wherein one side of the primary spraying tower is provided with a water feeding pipe I, and the other side of the water feeding pipe I is provided with a waste gas pipe; a tower plate is arranged on the inner surface of the primary spraying tower; one side of the solid-liquid reaction device is provided with cooling equipment, and the other side of the solid-liquid reaction device is provided with a drier; one side of the secondary solid-liquid reaction device is provided with a foam breaking mechanism, and an overturning plate is arranged on the inner surface of the foam breaking mechanism; one side of the overturning plate is provided with bulges; and one side of the secondary spraying tower is provided with an evaporator. The recovery equipmentdisclosed by the invention has the advantages that by the arrangement of the overturning plate, the bulges and the evaporator, reaction substances and mixed liquid can be mixed, and the purpose of uniform mixing can be achieved; and the recovery equipment can recover different types of gases, is applicable to different working conditions and can bring better use prospect.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a coating production waste gas recovery equipment. Background technique [0002] Coating is the application of a thin layer of plastic in liquid or powder form to the surface of objects such as fabrics, paper, metal foil or board for the purpose of anti-corrosion, insulation, decoration, etc. For example, the scraping method of applying PVC paste on the cloth base to obtain artificial leather, the casting coating method of coating on paper, the extrusion coating method of coating an extruded flat film on a substrate, The brush coating method of evenly brushing the paint on the substrate, in addition to roller coating, spray coating, powder coating, etc. Exhaust gas refers to the poisonous and harmful gas emitted by human beings in the process of production and life. Especially chemical plants, steel plants and pharmaceutical plants, as well as coking plants and oil refineries...
