Description

The invention relates to the field of spraying liquids and to devices for preparing liquid fuel for combustion, in particular, can be used for the disposal of liquid combustible waste.

The well-known "Method of preparing liquid fuel for combustion and a device for implementing this method."

Patent No. 2 107 172 - Prototype.

The given prototype considers preparation for burning volatile fuel - gasoline.

Meanwhile, in preparation for burning diesel fuel or used oil, the above method needs to be improved.

Improving fuel combustion is achieved by improving fuel atomization.

A diagram of a device for preparing liquid fuel for combustion is presented in figure 1.

The specified device contains:

- compressor drive 1;

- compressor 2;

- receiver 3;

- pressure gauge 4 receivers;

- gear 5;

- pressure gauge 6 of the fuel tank receiver;

- check valve 7;

- fuel tank receiver 8, made a single element;

- pipeline 9 for supplying air to the tank receiver;

- porous nozzle 10;

- regulator 11 for supplying an air-gas mixture;

- pipeline 12 for supplying an air-gas mixture;

- fuel supply regulator 13;

- fuel supply pipe 14;

- nozzle 15.

The purpose of the elements is as follows:

- compressor drive 1 - engine driving compressor 2;

- compressor 2 - compresses the air;

- receiver 3 - storage of compressed air reserves, smoothing ripples;

- pressure gauge 4 receiver 3 - pressure control in the receiver, compressor control;

- reducer 5 - installation and maintenance of the working pressure P _{1 of} compressed air in the fuel tank of the receiver;

- pressure gauge 6 of the fuel tank of the receiver - control of the working pressure P ₁ in the tank of the receiver 8;

- check valve 7 - preventing the ingress of fuel vapor into the receiver 3;

- fuel tank receiver 8, made by a single element, - storage of fuel reserves, equalization of air pressure, fuel and fuel vapor;

- pipe 9 for supplying air to the tank-receiver - air supply under pressure to the tank-receiver 8 under the fuel level through the porous nozzle 10;

- porous nozzle 10 - air dispersion under the fuel level in the receiver tank;

- regulator 11 for supplying an air-gas mixture - changing the amount of supply of an air-gas mixture without changing its pressure;

- pipeline 12 for supplying an air-gas mixture — supplying an air-gas mixture from a portion of the volume of the receiver tank above the fuel level to the nozzle 15;

- fuel supply regulator 13 — changing the amount of fuel supply without changing its pressure;

- fuel supply pipe 14 — fuel supply from a portion of the volume of the receiver tank under the fuel level to the nozzle 15;

- nozzle 15 - saturation of the fuel with air at a pressure of P ₁ , the issuance of the mixture in the zone with a pressure of P ₀ .

In the proposed device, air under pressure P ₁ through a pipe 9 is supplied to the tank receiver 8 under the surface of the fuel through the porous nozzle 10. The air passing through the fuel is saturated with vapors of light fractions of the fuel, while part of the air dissolves in the fuel. As a result, in the upper part of the tank-receiver 8, above the fuel level, a mixture of air and fuel vapors is formed, and the pressure of fuel, air and fuel vapors is evened out.

After the supply of fuel and air with fuel vapor into the nozzle 15, the fuel is saturated with air at the same pressure P _{1 of} fuel, air and fuel vapor. The absorption of fuel vapor by fuel does not occur, because in the tank-receiver 8 and the nozzle 15 the same pressure P ₁ .

From the nozzle 15, a mixture of air, fuel vapors and fuel saturated with air is supplied to the zone with pressure P ₀ , with P ₁ > P ₀ .

When the pressure decreases, air is released from the fuel in the entire fuel volume and fuel is atomized, while the presence of fuel vapor improves the process of ignition and combustion of fuel. The ratio of fuel and air supplied to the nozzle 15 with fuel vapors is regulated by the corresponding valves 13 and 11.
