Problems solved by technology

The main problems of this method are as follows: First, the quantitative spraying or quantitative atomization of liquid materials cannot be realized, which may easily cause the contradiction between supply and demand of medium heat and affect product quality.
This is because the continuous spray disperses the liquid into fine droplets, which have a large surface area, and the evaporation (flash) of water requires a lot of heat, and the superheating temperature of the heat medium or heating body cannot be too high, so the two are not easy to match
The second is that the adaptability of the nozzle is narrow, and different types and concentrations of liquid materials need to be replaced with different nozzles
The third is that the nozzle is prone to ice blockage in a high vacuum environment, that is, the nozzle is blocked by icing

Embodiment Construction

[0024] Such as figure 1 Shown is a schematic diagram of a vacuum dry explosion electronic control micro-spraying method. The voice coil motor (D), the microprocessor (MCU), the voice coil motor driver (PD), and the valve body (F) form the electronic control nozzle system. The mover (8) of the voice coil motor (D) is connected to the valve plug (2). After the mover coil is energized, it will reciprocate under the drive of the voice coil motor driver (PD) to drive the valve plug (2) to open or close the spray Hole (6); the microprocessor (MCU) generates an electric pulse signal to control the voice coil motor driver (PD), and changes the frequency and amplitude (voltage) of the electric pulse signal to change the voice coil motor mover (8) Displacement and the time it takes to complete a reciprocating movement, so as to control the degree of opening of the valve plug (2) each time and the time from opening to closing; the material liquid is input through the hose interface (4), an...
