Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] like figure 1 As shown, the structural principle diagram of the exhaust gas utilization system of the spray booth of the present invention is given, which includes a fan 2, a water mist pool 3, a combustion chamber 4, a gas tank 5, a paint drying room 6, a hydraulic pump 14, and an ignition device 16 . The fan 2 is provided with an air inlet pipe 7 and an air outlet pipe 8, and the fan 2 is respectively connected with the painting room 1 and the water mist pool 3 through the air inlet pipe 7 and the air outlet pipe 8, so that the fan 2 can spray paint in the painting room 1. The mixed gas produced in the process is sent into the water mist pool 3 . A plurality of atomizing nozzles 13 are arranged in the water mist pool 3, and the atomizing nozzles 13 are connected with the outlet of the water pressure pump 14, and the bottom of the water mist p...

Abstract

The invention relates to a waste gas utilization system for a paint spray booth, which is characterized by comprising a fan, a water mist pool, a combustion chamber and a paint baking room; an air inlet pipe and an air outlet pipe are arranged on the fan; the outer wall of the paint baking room is of a double-layer structure; a heating cavity is formed between the double-layer structure; the fan is respectively communicated with the paint spray booth and the water mist pool through the air inlet pipe and the air outlet pipe; the water mist pool is communicated with the combustion chamber through the air inlet pipe; an ignition device is arranged on the combustion chamber; the combustion chamber is communicated with the heating cavity of the paint baking room through a hot gas pipe; and an outlet through which the heating cavity is communicated with the outside is formed on the paint baking room. Through the waste gas utilization system, not only the recycling of effective components in paint and the heat utilization of combustible components are realized, but also the pollution caused by mixed gas to the atmosphere is avoided. The waste gas utilization system for the paint spray booth has the advantages of simple and reasonable structure, greenness and environmental friendliness, remarkable beneficial effects and convenience in application and popularization.

Description

technical field [0001] The invention relates to a waste gas utilization system in a painting booth, and more specifically, to a waste gas utilization system in a painting booth that can recover relatively large paint particles and burn flammable and toxic gases. Background technique [0002] In the anti-corrosion process of metal, especially for steel products or components, spraying paint layer is the most effective and main way. Large-scale iron and steel product manufacturing enterprises all have paint spraying booths, in which the painting of steel products is carried out. Working in the spray booth can prevent the poisonous and harmful gas substances produced during the painting process from entering the atmosphere, causing environmental pollution and endangering human health. [0003] The main components of paint are: oil, resin, pigment, thinner, auxiliary materials, etc. During the painting process, not only will there be fixed substances in the paint floating in t...
