Description

Technical Field

[0001] The utility model relates to an atomizing nozzle, in particular to a liquid atomizing nozzle. Background Art

[0002] At present, traditional disinfectant atomizing nozzles are usually integrated structures. Due to their complex internal structure, they are difficult to manufacture and have high processing costs. Moreover, in actual use, since the sprayed disinfectant is a corrosive liquid and the wind speed at the nozzle outlet reaches 80-120m / s, extremely high requirements are placed on the corrosion resistance and structural strength of the materials at the six gas injection holes of the nozzle. Usually, almost all nozzles are damaged at the six gas injection holes, and cracks and shedding usually occur. Once the gas injection holes are damaged, the entire nozzle needs to be replaced, which greatly increases the cost of use. In addition, in some special application scenarios, it is necessary to increase the temperature of the gas-liquid mixture. Common measures are: heating the liquid storage tank and / or heating the gun barrel air duct. Usually, both are heated independently at the same time. This method consumes a lot of energy and has poor results. Utility Model Content

[0010] The beneficial effects of the utility model are:

[0011] 1. The utility model divides the liquid atomizing nozzle into two independent parts, the injection body and the nozzle channel body, so that the injection body and the nozzle channel body can be made of different materials. The injection body is usually made of corrosion-resistant polytetrafluoroethylene, 316L, and Hastelloy material, while the nozzle channel body is usually made of PP, 316L or POM material, so that the materials of these two parts can be combined in various ways to achieve more economical and corrosion-resistant characteristics; moreover, when the injection body is damaged, it is only necessary to replace the injection body without replacing the entire liquid atomizing nozzle, thereby greatly reducing the cost of use.

[0012] 2.

It is efficient and safe, with a compact structure. It can effectively heat the disinfectant and the spray gas, promote the evaporation of the disinfectant, increase the gas temperature, and improve the gas-liquid mixing effect and the disinfection effect to adapt to various special application scenarios.

[0013] 3. The utility model can adapt to different disinfection scenarios by changing different nozzle channel bodies, which greatly reduces the cost of use.

[0014] 4. The injection body and the nozzle channel body described in the utility model can be directly connected by threads, or the injection body and the nozzle channel body can be tightened together by tightening screws, or the injection body and the nozzle channel body can be fixed together by positioning screws, making the installation of the injection body and the nozzle channel body very convenient.
