According to the atomization mechanism and experimental research, combined with the field experience of coal mines, the main ways to improve nozzle atomization are as follows:

(1) Increase the relative velocity difference between the gas and liquid phases to increase the aerodynamic force, so that the liquid droplets can be broken even more finely under the action of the larger aerodynamic force.

(2) Increase the exit velocity of the liquid phase nozzle to enhance the collision, so that the relatively ejected droplets can be further broken during the collision. Experiments have found that if the exit velocity of the droplets is small, large droplets will be gathered, and if the exit velocity of the droplets is high, the degree of atomization can be improved. However, this will reduce the relative velocity of gas and liquid and make the aerodynamic atomization of droplets worse.

(3) The experimental results show that the geometry and size of the nozzle and mixing tube have a great influence on the atomization performance. Therefore, when designing the model, in addition to considering their effects on atomization, the overall performance changes after they are combined should also be considered.

(4) Study the relationship between the flow and pressure of the spray water supply system and the geometric size and structure of the nozzle to improve the atomization effect. In particular, the water pressure of the water supply system has a greater impact on the atomization effect. The higher the water pressure, the finer the water mist particles. However, the problems caused by higher water pressure are: ① high energy consumption; ② all parts of the water supply system are under pressure, easy to malfunction, and have a short life span, especially the internal spray system on mining equipment. This brings us to another research topic: how to improve the pressure atomization nozzle structure to obtain fine water mist particles under the limited water supply pressure.
