Cone type nozzle with concentric circle dual pipe structure

摘要

The present invention relates to an ejector nozzle for mixing a small amount of chemicals into a large amount of raw water, such as water supply. More specifically, the present invention includes a cone-shaped nozzle having a concentric circular double tube structure in which raw water and chemicals can be quickly mixed. It's about ejectors.;The ejector having a cone-shaped nozzle with a concentric double tube structure according to the present invention inserts a smaller diameter tube into a relatively larger diameter tube by using two different diameter tubes. By using a double pipe of the structure assembled to be arranged in a concentric circle, the chemicals and pressurized water of the liquid to be mixed with the raw water to the two concentrically arranged pipe line formed by the double pipe to distribute the pressurized water, respectively Relatively increase the hydraulic pressure of the injection to high pressure, so that the negative pressure is generated at the tip of the nozzle is sucked into the chemicals and mixed with raw water.;The front end of the inner tube of the double pipe is formed to be shorter than the front end of the outer pipe so that the drug having a relatively low pressure hydraulic pressure is effectively sucked to the raw water side, and the tip of the nozzle to effectively mix the chemical sprayed from the double pipe structure nozzle with the raw water. Venturi tube type eductor is installed in front.
