The liquid fuel cavity sine treatment device operates as follows.

Liquid fuel is received into a cylindrical storage chamber 1 (FIG. 1) through an inlet pipe 2. liquid The fuel further passes through the nozzle 16 (FIGS. 2 and 3) and into the ultrasonic jet emitter. flow into the passageway formed by the inner surface 14 and outer surface 15 of the vane 11.12. Enter. The liquid fuel coming out of this passage is transferred to the vanes 11, 12 of the injection emitters 9, 10. The liquid fuel is directed to a curved barrier in the form of an inner surface connected to the curved barrier, where the liquid fuel is braked.

As a result, the flow energy of the liquid fuel is converted into the energy of high frequency vibrations of the liquid fuel. converted. This high frequency vibration has a predetermined frequency in the liquid fuel depending on the vibration strength. cause cavitation. This provides fundamental improvements in the operating characteristics of liquid fuels. Additional efforts will be made.

The maximum cavitation of liquid fuel is determined by the given parameters of the ultrasonic field (sound pressure, vibration frequency). This ultrasonic field is upstream of the nozzle 16 of the injection emitters 9 and 10. depends on the liquid fuel pressure and the shape of the injector 9.10.

The pressure valve upstream of the nozzle of the ultrasonic injection emitter 9.10 is It is optimal from the viewpoint of liquid fuel flow rate and physical and chemical characteristics of liquid fuel. properties (viscosity, density, surface tension). And this pressure valve is connected to inlet pipe 2. It can be adjusted by adjusting the provided bypass valve 25 (Fig. 1). There is. The pressure valve set to the set pressure is a pressure gauge (not shown) installed in the inlet pipe 2. can be monitored by.

The desired pressure of the liquid fuel upstream of the nozzle 16 (FIG. 2) of the injectors 9, 10 is determined by the voltage It can be freely adjusted by rotating the shaft 33 (FIG. 1). And this bo The bolt 33 compresses or expands the spring 30 by moving the connecting portion 31. This causes the pipe 28 to flow from the inlet pipe 2 through the bypass valve 25. It is designed to vary the amount of liquid fuel discharged.

Maximum capacitance within the liquid fuel fluid can be achieved by varying the flow rate and physicochemical properties of the liquid fuel. In order to cause biting, for the injection emitter 9 fixed in the storage chamber 1, The movable jet emitter 10 is moved by rotating the stem 22 of the screw 20.

In this case, the screw 20 moves along the axis 18 of the cylindrical storage chamber 1. As a result, Overlapping amount of the inlet nozzles 16 (FIGS. 2 and 3) of the ultrasonic jet emitters 9 and 10 changes.

Although the cross-section of the passages varies, the shape of these passages and the injection emitter of the liquid fuel fluid 9. The velocity at nozzle 16 population of 10 does not change.

Due to changes in the flow rate of the liquid fuel moving within this device, the inlet piping 2 (Fig. 1) No change in constant pressure.

Even if the flow rate of the liquid fuel fluctuates, the bypass valve 25 directs excess liquid fuel to the pipe 28. The pressure of the liquid fuel is kept constant by discharging it from the tank. Inside the inlet pipe 2 The optimum pressure for a given liquid fuel is set by a bypass valve 25 held by a locking nut 34. It is set by moving the bolt 33 of.

Therefore, the device according to the invention allows only a predetermined amount of fuel to be processed and the liquid fuel Avoiding unnecessary expenses in dealing with surplus quantities. This device can handle all types of liquid fuels. and over the entire range of liquid fuel flow rates regardless of its physicochemical properties. This enables maximum strength cavitation treatment.

During operation of the device, variations in the physicochemical properties of the fuel (e.g. heating of the fuel) may cause Changes may occur in the predetermined flow rate of the fuel being processed. In this case, liquid fuel The predetermined flow rate is determined by the vanes 11, 12 of the ultrasonic jet emitters 9, 10 as described above. This can be adjusted by changing the cross-sectional area of the passage.

Modify for long-term processing other liquid fuels with different physicochemical properties If so, operate the adjustable bypass valve 25 (as described above) to Set a new pressure, make this pressure the optimum value for the given fuel, and It is necessary to detect the pressure with a pressure gauge.

After adjusting the position of the bolt 33 of the adjustable bypass valve 25 as necessary, The bolt is held in the new position by a locking nut 34.
