Double face side absorption type spray system

Abstract

The invention relates to a double face side absorption type spray system. The double face side absorption type spray system comprises an air inlet, a dynamic pressure chamber, a static pressure chamber, a paint spray chamber and a paint mist separation chamber, which are sequentially arranged from the top down, wherein two rows of paint mist trapping devices are symmetrically arranged in the paint mist separation chamber, air inlets of the two rows of the paint mist trapping devices are oppositely arranged, and stream guidance spaces for leading air to flow are left between the two rows of the paint mist trapping devices and on the upper portions of the paint mist trapping devices. Compared with the prior art, the paint mist trapping devices respectively arranged on two sides of the paint mist separation chamber can increase the draught area and the separating area of the air in multiples, the quantity of paint mist trapping units and paint mist trapping absorption ability can be greatly improved, replacement frequency of the paint mist trapping units is reduced, and the stream guidance space left between the two rows of the paint mist trapping devices, located on the two sides of the paint mist separation chamber, can homogenize loads of all the paint mist trapping units, and can improve the trapping absorption ability of the paint mist trapping units for paint mist and stability of the double face side absorption type spray system.

Description

technical field [0001] The present invention relates to the field of industrial painting, in particular to the field of capture, separation and collection of paint mist in a dry spraying system, in particular to a double-sided side-suction dry spraying system, which is widely used in automobiles, hardware, home appliances and toys. field. Background technique [0002] With the rapid development of China's economy, environmental pollution has become more and more serious. In most parts of our country, human pollution of air, soil and water has far exceeded the capacity of nature. In recent years, smog has occurred frequently, and water pollution and soil pollution have become more and more serious. Painting is a highly polluting and energy-intensive industry. During the coating production process, a large amount of exhaust gas, waste liquid and solid waste will be generated. In order to maintain the constant temperature and humidity environment required for painting, pain...

AI Technical Summary

Problems solved by technology

[0006] Although the current dry-type paint mist collection unit with impact or filter technology has achieved a large paint mist collection capacity, the structure of the spraying system is still similar to the traditional Venturi spraying system. The exhaust air form of a single channel, the exhaust air area is small, and the exhaust air is more concentrated

There is a single exhaust channel in the middle, the exhaust outlets are concentrated, the installation space of the paint mist capture unit is limited, and the number of paint mist capture units is small; when the number of paint mist capture units is small, the paint mist capture The collection device has limited capacity to capture paint mist

Therefore, the frequency of replacement of the paint mist collection unit is still high, and the stability of the entire spraying system needs to be improved.
