Abstract

The invention discloses a two-fluid spray device and a two-fluid atomization method. The device comprises an air inlet assembly, a water inlet assembly, a mixing assembly, a breaking target pin and a spray assembly, wherein a water and vapor mixing cavity is formed in the hollow interior of the mixing assembly; the outlets of the air inlet assembly and the water inlet assembly both communicate with the mixing cavity of the mixing assembly; an outlet of the mixing assembly communicates with the spray assembly; and part of the breaking target pin is inserted in the mixing assembly in a penetration manner and used for breaking water introduced by the water inlet assembly. According to the two-fluid spray device, the two-fluid internal mixing design is adopted and the water is broken by adopting the breaking target pin, so that water mist sprayed during atomization by utilizing the device is proper and uniform in particle size.

Description

technical field [0001] The invention relates to a spraying process, in particular to a dual-fluid spraying device and a dual-fluid atomization method. The device and method can be applied to icing wind tunnels, LCD depth cleaning, circuit board cleaning, semiconductor cleaning, TFT precision flushing, and polysilicon flushing , low temperature wind tunnel, spray humidification and precision spraying and other fields. Background technique [0002] Existing spray devices only set a predetermined pressure with water and others, and then allow water vapor in the atomization chamber, which makes it difficult to mix the water vapor uniformly, and also causes uneven particle size of the water mist. For example, the spray device used in the icing wind tunnel (English: icingwindtunnel); the spray device is a key component to realize the simulation of large particle size cloud and fog parameters in the icing wind tunnel. However, the particle size of the existing spray device is diff...
