The pressure relief valve of the air compressor has an output pressure of 0.5MPa.

The invention has the advantages of simple structure, reliable operation, strong droplet penetration, droplet diameter less than 50 μm, convenient operation, strong maneuverability, and adjustable spray temperature within a certain range.

Description of drawings

Fig. 1 is a structural schematic diagram of the present invention.

Detailed ways

As shown in Figure 1, a temperature-adjustable mist diffuser includes an air compressor 1 and a main liquid pump 7, the inlet of the main liquid pump 7 is connected to the water inlet pipe, and the outlet of the main liquid pump 7 is connected to the working fluid of the ejector 11 Inlet, the suctioned fluid inlet of the ejector 11 is connected to the suction control valve 10, the liquid suction control valve 10 is connected to the suction pipe 9, the suction pipe 9 is placed in the liquid medicine tank 8, and the mixed fluid outlet of the ejector 11 is connected to the injector 5 The suctioned fluid inlet of the injector 5 is connected to the control valve 4, the control valve 4 is connected to the hot end of the vortex tube 3, the cold end of the vortex tube 3 is suspended, and the inlet of the vortex tube 3 is connected to the pressure reducing valve 2 The exhaust pipe of the air compressor 1 and the mixed fluid outlet of the injector 5 are connected to the remote spray gun 6 .

The pressure reducing valve of the air compressor 1 has an output pressure of 0.5 MPa.

It works as follows:

When the air compressor 1 is working, the air at room temperature and normal pressure is inhaled through the suction port, and after compression, the compressed air with a gauge pressure of 8kg/cm2 is discharged from the exhaust port. After the nozzle of the tube 3 expands, it enters the vortex chamber at a high speed along the tangential direction, forming a free vortex. After the exchange of kinetic energy, it is separated into two parts with different temperatures. The airflow in the central part flows out through the orifice plate, that is, the temperature can be controlled Cold air flow up to - 10~- 50°C; the gas at the edge flows out from the other end through the control valve 4, which is a hot air flow with a temperature up to 100~130°C. The high-pressure hot gas flow sent from the hot end tube of the vortex tube 3 enters the ejector 5 and becomes a supersonic high-speed air flow, forming a negative pressure state at the outlet of the nozzle inside the ejector 5 . The main liquid pump 7 pressurizes the water flow in the water inlet pipe to a high pressure state of 3~5kg/cm2, enters the ejector 11, forms a negative pressure state at the outlet of the nozzle of the ejector 11, and sucks the liquid medicine in the liquid medicine tank 5 , mixed with water in a high-pressure state to produce an imbibed liquid with good mixing ratio stability, which is sent into the mixing chamber of the eductor 5 through the inhaled fluid inlet of the eductor 5, and injected from the nozzle inside the eductor 5 The high-speed hot air is uniformly mixed in the mixing chamber, and sent to the remote spray gun 6 through the connecting hose to spray out the mist with small mixing ratio, high pressure ratio and adjustable temperature.
