Description

 The invention relates to techniques for the preparation of emulsions, which can be used as an alternative fuel for internal combustion engines.

 A device is known for cyclically producing a water-fuel emulsion (VTE), consisting of a tank, dispersant, filters for water and fuel, gear pumps, an overflow valve, a three-way valve, shut-off and isolation valves. After filling the tank with the initial components, the fuel pump drives the liquid along the closed loop tank-pump-tank, the dispersant is a liquid whistle, the required size of the dispersed phase and the stability of the emulsion is achieved by multiple passage of liquid through the dispersant (Lebedev O.N., Somov V.A. Water-fuel emulsions in marine diesel engines. L .: Shipbuilding, 1988, 62 S.).

 The closest analogue is the device presented in the copyright certificate SU 1669516 A1, 4714388/26, B 01 F 3/08, consisting of tanks for water and fuel, filters for water and fuel, shutoff valves, low pressure pump, high pressure pump, dispersant with nozzles installed on it and a collapsible column attached to it. The fuel from the tank enters through the appropriate filters to the low-pressure pump, where the initial coarse dispersion of the fuel and water flowing through the filter from the water tank takes place. From the booster pump, the emulsion enters the low pressure cavity of the high pressure pump and is injected through the nozzles into the dispersant cavity, where the final dispersion occurs due to the injection energy, the excess emulsion enters the collapsible column, and then it is fed to the engine power system.

 However, known devices, including and adopted as the closest analogue, they do not allow to control the quality of VTE in the process of its preparation, do not provide automatic control of the quality of VTE, do not allow to obtain an emulsion of any desired composition.

 The technical task is to monitor the quality of VTE in the process of its preparation, the possibility of obtaining an emulsion of any desired composition.

 This problem is solved in that, in contrast to the closest analogue, the installation is equipped with an automatic density measuring device with an electromagnetic valve, the dispersant is made in the form of a reactor with the nozzles tangentially arranged to the middle circumference of the reactor chamber, and a primary density transducer with the ability to move it along the height is installed on a collapsible column.

 These differences allow us to provide the ability to control and set the water content during the preparation of VTE when moving the primary density transducer in a vertical plane. This installation allows you to automatically adjust the supply of water from any stationary water system to the lower part of the reactor with a tangential arrangement of nozzles to the middle circumference of the inner chamber of the reactor and makes it possible to obtain VTE of any desired composition.

 The drawing shows a schematic diagram of an installation for the preparation of water-fuel emulsion.

 The installation contains tanks for fuel 1 and water 2, fuel filters 3 and water 4, a solenoid valve 5, a multi-section high pressure pump 6 with electric drive 7, a dispersant in the form of a reactor 8 for preparing a water-fuel emulsion. The internal cavity of the reactor 8 is connected on one side to the column 9, and through the check valve 10, it is connected to the emulsion bypass line to the fuel tank, and on the other, it is connected with nozzle nozzles 11 installed tangentially to the middle circle of the reactor chamber 8 and connected by high pressure pipelines with a multi-section high pressure pump 6, the low pressure cavity of which is connected to the tank 1 through the check valve 12 and the fuel filter 3; to the lower part of the reactor 8 through a nozzle (not shown in the diagram), a cut-through valve 13, a water filter 4 and an adjustable solenoid valve 5 are supplied with water from the tank 2. A collapsible column 9 is connected through a check valve 14 to the engine power system and, on the other hand, is connected to the primary density transducer 15, which is connected by electrical communication with the secondary density transducer 16, the control solenoid valve 5. It is possible to connect the installation to a stationary water supply network through valve 17. In the lower part of the reactor there is a drain valve 18.

 It is also possible to install slot devices (not shown in the diagram) for additional dispersion of the prepared emulsion.

 Installation for the preparation of water-fuel emulsion works as follows.

 Fuel from the tank 1, which is under constant pressure due to the high location, through the check valve 12 and the corresponding fuel filter 3 enters the low pressure cavity of the multi-section high pressure pump 6 with electric drive 7 and into the internal cavity of the reactor 8, water from the tank 2 under constant pressure or due to the operation of the hydrophore system (water system) through the check valve 13 or valve 17 and the corresponding water filter 4 through a pipeline with an electromagnetic valve 5 enters the inner cavity of the reactor RA 8, where fuel is injected into the water in a certain way arranged by nozzles 11 and then dispersed due to high-speed flows of atomized fuel passing through the low pressure cavity of the high pressure fuel pump 6 - high pressure pipeline - nozzles 11. The ratio between fuel and water is determined by the passage the cross-section of the water supply pipe (nozzle) and can be changed by acting on the controlled solenoid valve 5 with a signal of an automatic measuring device density grains. Under the excess pressure arising in the reactor 8, the resulting water-fuel emulsion passes to a collapsible column 9, where the emulsion is distributed depending on its density over the height of the collapsible column 9. The water-fuel emulsion of the required water content (this is determined by the location of the primary converter of the automatic device for measuring the density of the emulsion 15) through the check valve 14 enters the fuel system of the engine. The excess water-fuel emulsion through the non-return valve 10 enters the fuel supply tank 1, and then through the valve 12 and the fuel filter 3 into the low pressure cavity of the high-pressure pump 6 goes to the repeated circulation circle, which allows to obtain the required multiplicity of VTE preparation.

 The water content in the VTE is set using an automatic density measuring device consisting of a primary density transducer 15 connected by electrical connection to a secondary density transducer 16 and issuing a control signal to the electromagnetic valve 5. A standard device for controlling the level in a tank of this type is used PRU-5m. The specified water content in VTE is maintained in accordance with the principles of density distribution over the height of column 9, while a metallized float (not shown in the diagram) of the primary density transducer 15 with a given density of material in the ball volume equal to the required density of VTE determines the response time of the secondary density transducer 16 and further of the electromagnetic valve 5, which provides a discrete time supply of the required amount of water from the tank 2 to the reactor 8. The primary Converter density 15 due to the elastic connection to the column 9 can move in a vertical plane, which allows you to control the water content of VTE, selected to consumers through the valve 14.

 From the upper part of the collapsible column 9, through the non-return valve 10, the VTE part is sent to the fuel tank 1, due to which the emulsification rate is ensured with the valve 14 closed.

 With a long interruption in operation by turning off the valve 13 (17), it is possible to clean the system from water when the drain valve 18 is opened and the system is then operated for a short time on clean fuel.
