Description

Two-fluid micro-mist device

The two-fluid micro-mist device of the present invention is mainly applied to the technology of using the pressurized air sprayed in the middle to further micro-atomize the water vapor sprayed from both sides, so that the effect of micro-atomization is better.

The two-fluid nozzle is a nozzle that uses a principle of high-speed flow of compressed air to make the liquid micronized. Its characteristics are as follows: 1. Excellent micronization performance. Second, the adjustment range is large. When the particle size and flow distribution are kept constant, the adjustment range of the spray flow rate can be increased, and the nozzle can adjust the spray amount. 3. The foreign matter passes through the larger diameter and the fluid nozzle of one of the same water quantity, and the foreign matter passage diameter is larger. Therefore, it can effectively prevent the blockage.

The current siphon nozzles on the market utilize the principle of siphoning to generate a pressure difference in the nozzle mixing section with compressed air, and to mix the liquid into the mixing section to mix with the gas, and finally to spray the mixed fluid. However, nozzles are prone to errors during processing, which can lead to instability and unevenness of micro-atomization, especially nozzles that have not been polished, which can cause drag and turbulence in the nozzle. At the same time, the existing two-fluid nozzles can maximize the atomization of liquids, and generally only reach the average particle size of 10 μm, which is a problem that still needs to be solved and is missing.

The creator is currently engaged in the manufacture and design of related products, accumulated many years of practical experience and experience, and actively engaged in the spirit of innovation and improvement in response to the existing problems and lack of traditional two-fluid nozzles. Device.

The technical means applied by the new problem solving and the efficacy against the prior art are: using the siphon principle, a part of the pressurized air is directly ejected from the nozzle of the center of the spraying device, and the other part of the pressurized air is indirectly caused by the two sides. The spray head is sprayed out, so that the water of the container body is first sucked out by the siphon tube, and then sprayed out from the discharge pipe of the spray group, and when the pressurized air and the water are atomized and sprayed from both sides, the pressurized air sprayed from the middle is used. Further, the water atom is micro-atomized, so that the effect of micro-atomization is better, and the average particle diameter is 10 μm or less, and the efficiency is improved, and the main purpose is achieved.
