The steam pressure is generated by the boiler, and the steam pressure is not adjusted as conveniently as compressed air, and the steam pressure can influence the change of the steam flow. The change of the steam flow not only affects the temperature change, but also directly affects the atomization effect of the liquid. In the chemical industry, most of humidification and heating processes are in chemical reaction stages of raw materials, and incomplete reaction of the raw materials can be caused by temperature and humidity changes, so that the quality of the generated product can be influenced finally. On the tobacco shred production line, the change of temperature and humidity can directly lead to disqualification of the product.
At present, no special nozzle is arranged in the heating and humidifying process, the air atomizing nozzle is directly used for realizing the heating and humidifying process, and the flow of compressed air is realized by means of gas pressure adjustment.

On tobacco shred production lines in the chemical industry and the cigarette industry, many occasions needing humidification and warming exist. These applications require special nozzles that use steam heating and atomization of the liquid. The steam pressure is generated by the boiler, and the steam pressure is not adjusted as conveniently as compressed air, and the steam pressure can influence the change of the steam flow. The change of the steam flow not only affects the temperature change, but also directly affects the atomization effect of the liquid. In the chemical industry, most of humidification and heating processes are in chemical reaction stages of raw materials, and incomplete reaction of the raw materials can be caused by temperature and humidity changes, so that the quality of the generated product can be influenced finally. On the tobacco shred production line, the change of temperature and humidity can directly lead to disqualification of the product.
At present, no special nozzle is arranged in the heating and humidifying process, the air atomizing nozzle is directly used for realizing the heating and humidifying process, and the flow of compressed air is realized by means of gas pressure adjustment. When the air atomizing nozzle is directly used in the steam atomization, the adjustment of the pressure can not only influence the steam flow, but also directly influence the change of the temperature, so that the atomization effect of the liquid is influenced.
When the existing atomizing nozzle is used, once the atomizing nozzle with one parameter is selected, the parameter of the atomizing nozzle is fixed, the flow rate of the nozzle can be changed only by adjusting the air pressure and the liquid pressure, and the adjustment of the spraying angle and the spraying distance can not be realized. Because the atomized material diameter of the liquid is regulated by means of gas pressure, the variation of the gas pressure can cause great variation of the steam flow due to the difference between the compressed air and the steam, so that the variation of the temperature and the atomized material diameter can be directly influenced, and the production is difficult. Meanwhile, the common air atomizing nozzle is limited by the structure, so that the nozzle is not easy to install on a production line, and the scale generated by steam is easy to block the spray hole, so that the nozzle cannot work normally.
Accordingly, in view of the above problems, the present application proposes a steam humidifying micro mist nozzle.
The steam humidifying micro mist nozzle provided in the present application is described below with reference to fig. 1.
