The invention relates to automatic control and can be used in the chemical, food and other industries.

The purpose of the invention is to expand the scope and improve the performance of the system.

In FIG. 1 is a schematic diagram of a system; in FIG. 2 - outline the ink jet. :, - The systra will contain the first 1 and second 2 containers of components, the first 3, the second 4 and the third 5 mixers equipped with the main 6,7,8 and injecting 9,10,11 inputs and outputs 12, 13, 14, pump 15 and regulating valves 16, 17, 18, 19, 20, 21.

Each mixer is made in the form of a jet mixer (Fig. 2), the main inlet of which is formed by an accelerating nozzle 22, the injection inlet is connected to a pre-chamber 23 connected through a mixing chamber 24 to the outlet of the mixer, made in the form of a diffuser 25, forming a zone of reduced pressure. The first mixer 3 forms with the valve 18, the second mixer 4 and the pump 15 the main circuit of the mixture, and the valve 17 and the third mixer 5 - the additional circuit of the mixture, and the output 12 of the first mixer is connected through the consumer 26 with the injection inputs 7 and 11 of the second and a third mixer with the formation of the respective recirculation circuits of the mixture with valves 20 and 21 and a common valve 19. A second tank 2 is connected to the injection input 9 of the first mixer and the output 14 of the third mixer through the valve 16,

The system works as follows,

When the pressure pump 15 is turned on, the main (working) component of the mixture from the tank 1 is pumped into the mixer 3. The mixers 3, 4, 5 are of the same type and are inkjet devices working with; the implementation of a supersonic condensation-pressure-compression shock wave.

The passage through mixers 3, 4, 5, the main and injected (additional) components of the mixture are intensively dispersed and homogenized and form a mixture in the form of a finely dispersed emulsion with an inclusion size of not more than 1.2 microns, and the mixers perform a dosing function. Perturbations at the mixer outlet not exceeding half the pressure of the flow of the working component at the mixer inlet; against the flow do not extend.

The flow of the working component of the mixture, injected into the mixer 3, injects an additional component of the mixture located in the tank 2. The finely dispersed mixture after the mixer 3 is partially supplied to the consumer. The rest of the mixture goes to

the inlet of mixers 4 and 5. After mixer 5, the mixture is fed into mixer 3 into the vacuum zone behind the booster nozzle. In this case, the amount of the additive component injected into the mixer 3 is accordingly reduced.

.0 from tank 2.

After the mixer 4, the mixture enters the inlet of the pump 15, and together with the working component from the tank 1, the amount of which decreases accordingly, is pumped into

5, mixer 3, after which the process is repeated. With this circulation, the concentration of the additive component is retained mainly. Concentration is established by placing in the mixers 4 and 5 booster

0 nozzles of a certain diameter.

A more precise adjustment of the concentration is carried out by the valve 16.

With increasing pressure at the inlet of the consumer (i.e., if necessary

5), the part of the emulsion passing to the mixers 4 and 5 increases, and the part going to the consumer decreases. Due to the increase in the amount of circulating emulsion, the flow of components from containers 1 and 2 decreases accordingly. When the pressure decreases at the consumer (i.e., if necessary, increase the flow rate of the mixture), the portion of the mixture supplied to the consumer increases and the flow rate of the mixture through emulsifiers 4 and 5 decreases accordingly.

Emulsion flow rate can be manually adjusted by valve 1.9. If necessary, excess mixture is injected into the mixers

0 5 and 4 through valves 20 and 21, the system allows you to get a mixture with a given flow rate and concentration.

In some cases, it is necessary for the consumer to obtain a mixture with a constant consumption of one of the components when the flow rate of the other is changed.

So, when operating diesel engines on water-fuel emulsions, some is optimal for the combustion process.

0 constant value of water consumption, independent of fuel consumption.

For this case, the circuit provides valves 17, 18. When closing one of these valves, the flow rate of the corresponding

5 component will be constant.

Varying the degree of shut-off of valves 17 and 18, the amount of mixture passing to mixers 4 and 5 can be changed, and when closing valves 17, 18, 20, 21, the system acts as a stabilizer for the flow rate of the mixture.
