The well-known gas station is a container one and provides only fueling cars with gasoline and diesel fuel without the possibility of filling the tankers of small tankers with diesel fuel.

The closest to the proposed invention in technical essence is a general-purpose automobile gas station (gas station), consisting of the zone of an automobile gas station, operator, canopy, tanks for storing various types of fuel, refueling columns, process pipelines, a tank discharge platform, an emergency tank, treatment facilities, automatic monitoring and control systems, fuel level measurement systems in tanks, fire and security alarms, systems Lightning protection and grounding (RD 153-39.2-080-01 Rules for the technical operation of gas stations. Moscow, 2001 - prototype).

Known gas stations are stationary. The gas station provides only the refueling of trucks and cars with gasoline and diesel fuel. The possibility of filling the tanks of small tankers with diesel fuel at the gas station is not provided.

The proposed invention solves the problem of providing refueling at a single station of trucks and cars with gasoline and diesel fuel and filling the tanks of small-capacity tankers with diesel fuel. The problem is solved by the fact that a car gas station, consisting of a zone of a car gas station, a control room, a canopy, tanks for storing various types of fuel, fuel columns, process pipelines, a tank drainage site, an emergency tank, treatment facilities, an automatic control and management system, systems for measuring the level of fuel in tanks, fire and security alarm systems, lightning protection and grounding, according to the invention, further comprises a technological the Pole system, which includes a loading unit, a riser with quick-disconnect tight connections and flexible hoses, a valve connecting the supply and gas return pipelines at the highest point, a pipeline for supplying diesel fuel from the storage tank to the loading unit, a closed fuel loading system to the tanker, a system for deaeration and recirculation of displaced fuel vapors from a refueling tanker to a storage tank with a gas return pipeline, a system for the stepwise release of fuel at the beginning and at the end of a dose s with a filling speed of not more than 1 m ³ / s, a set of sensors that provide controlled loading of diesel fuel into the tanker, an electrical circuit, a tank grounding monitoring system, a system for automatically monitoring the concentration of fuel vapor in the free space of wells and tank mines, a system capacity monitoring complex deaeration and recirculation, a fuel level measuring system, a system for preventing the combination of loading and unloading operations, a preliminary testing system for the presence of t fuel in the refueling tanker, a refueling tanker overflow prevention system with an alarm subsystem for reaching a 90% nominal filling level and a blocking overfill subsystem when reaching a 95% filling level with automatic shutdown of diesel fuel supply and a manual diesel fuel supply switch.

An automobile gas station with the Pole technological system also contains a diesel fuel discharge and loading platform from a tank truck, an additional tank for storing diesel fuel to be drained, an emergency tank, a drain well, a loading block, and a slag tank.

SUMMARY OF THE INVENTION

For refueling technological vehicles (tractors, combines, trucks) in the field, small-capacity tankers of the order of 3-5 m ^{3 are used} . Pouring into such tankers at ordinary gas stations is impossible, and refueling at oil depots is unprofitable for economic reasons due to the large distances and unjustified runs from oil depots to technological vehicles, which are usually in the field. The proposed invention solves the problem of bringing fueling stations closer to diesel-fueled technological vehicles by providing fueling at a gas station for cars and trucks with gasoline and diesel fuel and filling small tanker tanks with diesel fuel. The problem is solved as follows.

At existing gas stations of general civilian use, which are close to the consumer, they mount the technological system "Field" (TS "Field"), on which small-capacity tankers refuel. Due to the proximity of existing gas stations to the places of work of technological vehicles, the distances and unjustified runs of tankers are reduced. It is not possible to solve the problem by simply supplementing the gas station with a refueling unit for small tankers due to the fact that such a unit requires compliance with fire and other rules that can easily be implemented in oil depots and which are difficult to fulfill at the gas station. So, for example, filling diesel fuel into a tanker in a tank farm is done through an open neck, which is completely unacceptable in a gas station. In addition, there are restrictions on remoteness from roads, on the area of the refueling unit’s refueling site, and much more.

The placement of a small volume tanker loading unit on the territory of a gas station was made possible by applying a number of measures to ensure fire safety rules, safety precautions, the organization of work and the corresponding equipment with instruments and equipment.

A typical gas station, among other things, includes a gas station area, a control room, a canopy, tanks for storing different types of fuel, fueling stations, process pipelines, a tank discharge site, an emergency tank, treatment facilities, an automatic control and management system, and a system measurement of fuel level in tanks, fire alarm, lightning protection system and grounding. In the proposed invention, the gas station with the vehicle "Field" also performs its basic functions as a regular gas station to provide civilians with oil products at retail, i.e. provides refueling of cars and trucks with gasoline and diesel fuel. In addition, the proposed filling station with the TS "Pole" allows you to additionally refuel small tankers in compliance with the requirements and standards of fire safety, environmental safety and electrical safety.

TS "Field" includes:

1. bulk riser with quick-disconnect tight connections and flexible sleeves;

2. a valve connecting the supply and gas return pipelines at the highest point;

3. a pipeline for supplying diesel fuel from the storage tank to the bulk riser;

4. a closed system for loading diesel fuel into a tanker;

5. a system for deaeration and recirculation of displaced fuel vapors from a refueling tanker to a storage tank with a gas return pipe;

6. a system of step-by-step dispensing of fuel at the beginning and at the end of a dose with a filling speed of not more than 1 m ³ / s;

7. A set of sensors providing controlled loading of diesel fuel into the tanker;

8. electrical circuit;

9. tanker ground control system;

10. A system for automatically monitoring the concentration of fuel vapor in the free space of wells and tank mines;

11. complex control of the throughput of the deaeration and recycling system;

12. a system for measuring the level, density, temperature of fuel and the level of produced water;

13. a system for preventing the combination of discharge and loading operations;

14. a system for preliminary testing of fuel availability in a refueling tanker;

15. a refueling tanker overflow prevention system with an alarm subsystem to achieve a 90% nominal filling level;

16. blocking subsystem from overflow when the maximum filling level of 95% is reached with automatic shutdown of diesel fuel supply;

17. manual switch for the supply of diesel fuel.

Thus, the placement on the territory of the NPP of a loading block for small tankers has become possible with the use of the TS "Pole", including items 1-17.

General view of the gas station with the vehicle "Field" is presented in figures 1 and 2.

A gas station consists of zones of a car refueling station 1, an operator’s 2, a canopy 3, tanks for storing different types of fuel 4, refueling columns 5, process pipelines 6, a tank discharge platform 7, an emergency tank 8, treatment facilities 9, and an automatic monitoring and control system 10, systems for measuring the level of fuel in tanks 11, security and fire alarms 12, lightning protection and grounding systems 13.

The TS Pole loading block consists of a bulk riser 14 with flexible hoses 15 equipped with quick-disconnect tight connections 16, a fan 18 connecting the supply and gas return piping 17 at the highest point, a pipeline for supplying diesel fuel 19 from the storage tank 20 to the bulk riser 14, closed fuel loading system 21 into the tanker 22, deaeration and recirculation systems of displaced fuel vapors 23 from the tanker 22 to the storage tank 20 with a gas return pipe 24, the system of step-by-step fuel dispensing in at the beginning and at the end of dispensing a dose of 25 with a filling speed of not more than 1 m ³ / s, a set of sensors 26 that provide controlled loading of diesel fuel into the tanker 22, the electrical system 27, the ground monitoring system 28 of the tanker 22, the automatic control system for the concentration of fuel vapor 29 in the free space of the wells and shafts of the tank, the throughput monitoring system of the deaeration and recirculation system 30, the fuel level measuring system 31, the system for preventing the combination of loading and unloading operations 32, s preliminary testing systems for the presence of fuel 33 in the tanker 22, overfill prevention systems 34 of the tanker 22 with an alarm subsystem for reaching a 90% nominal filling level and a blocking system for overfilling when the filling level reaches 95% with automatic shutdown of diesel fuel supply and a manual switch diesel fuel supply 35.

A nuclear power plant with TS “Pole” contains a diesel fuel discharge / loading platform 36 from a tank truck, an additional tank for storing diesel fuel to be drained 37, an emergency tank 38, and a drain well 39.

The bulk riser 14 consists of telescopic tubes 40 with counterweights 41, on which flexible sleeves 15 with quick-disconnect tight connections 16 in the form of quick-detachable couplings are fixed. Flexible hoses 15 are designed for loading fuel into the tanker 22 and for recirculation of fuel vapor in a closed loop during unloading operations. At the highest point, the flexible hoses 15 are connected by a valve 18 to a pipe 17. After filling the tanker 22, when the valve 18 is opened, the remaining diesel fuel is drained from the flexible sleeve 15 of the riser 14 to the tanker 22. The diesel vapor is transferred from the tanker 20 to the flexible sleeve 15 with its liquid phase after blocking the fuel supply pipe to the bulk riser 14.

Flexible hoses 15 are connected to the pipeline for supplying diesel fuel 19 from the storage tank 20. The hydraulic unit 42 provides the supply of diesel fuel to the bulk riser 14, gas separation, filtering the fuel and converting the amount of fuel delivered into electrical impulses with subsequent transmission of information (in volume units) to indicator board of the controller and remote control.

A closed system for loading diesel fuel into the tanker 22 is provided with couplings 16 for connecting the flexible hoses 15 of the bulk riser 14 to the corresponding nozzles of the tanker 22. The couplings 16 provide self-closing when disconnecting these connections. Clutches 16 are connected to the grounding system 13. The equipment of the bulk riser 14 has the necessary equipment for fireproof emptying of it from fuel and its vapors in preparation for repair or routine maintenance.

The pipeline for supplying diesel fuel 19 from the storage tank 20 to the bulk riser 14 is made without collapsible joints and laid underground.

The system of deaeration and recirculation of fuel vapor 23 provides fire and explosion safe communication with the atmosphere of the free space of the tank 4 and recirculation of fuel vapor in a closed loop during discharge and loading operations at gas stations. The recirculation of fuel vapor when filling the tanker 22 with diesel fuel from the storage tank 20 is carried out through the gas return pipe 24. The recirculation line is equipped with an automatic throughput control system 30 that ensures that the fuel vapor pressure in the pipelines exceeds the limits of the return valves of the recirculation system and automatically generates a warning signal and turns off tanker loading unit pump 22.

The system of step-by-step dispensing of fuel 25 is located directly in the pipeline 19 and is designed to shut off and step-by-step regulation of the fuel flow at the beginning and at the end of the dispensing of a dose (by the command of the controller), which ensures the exact delivery of a given dose. The minimum flow rate is not more than 1.0 m ³ / s. The minimum flow rate is set by the operator and is set from the control device.

The system for preventing overflow 34 of the tank of the tanker 22 when receiving fuel from the storage tank 20 includes a number of electrical overflow sensors installed on the caps of the necks of each compartment of the tanker 22 connected through a special outlet to the control controller of the shut-off valve of the filling unit. These sensors provide a self-monitoring function, as a result of which the operator can be sure that the system is functioning properly before the filling process begins.

All components are explosion and fireproof.

Through the electrical system 27, the safety unit, when connected to the tanker 22, constantly tests the condition of the product presence sensors and overflow sensors.

Before issuing a refueling permit for the tanker 22, the sensors 33 for the presence of fuel in the tanker 22 are tested by the system 33, and if there are product residues in the tanker compartment 22, a refueling permit is not issued.

During filling, the overfill prevention system 34 constantly tests overflow restriction sensors on the tanker 22 and when it reaches the 90% (by volume) level of the tank of the tanker 22 it gives a sound and light signal about the need to stop filling, and at 95% (by volume) ) the filling level stops the fuel supply.

The system of automatic control of the concentration of fuel vapor in the technological wells and shafts of tank 29 when the concentration of fuel vapor reaches 20% of the limit automatically gives a light and sound signal, closes the drain or shuts off the power to the transfer pumps, closes the barrier at the entrance to the gas station.

The conductive equipment of the TS "Field" is equipped with nodes for connecting to the grounding system of 13 gas stations.

The system of automatic prevention of inadmissible combination of unloading and loading operations 32 ensures that the power supply to devices that dispense fuel from the tanks to be filled is turned off, the power supply to the filling device is turned off, the filling line is closed by gravity or the pumping pumps that are not related to the filling line of the remaining fuel storage tanks are closed, and the barrier is closed at the entrance to the gas station.

On the loading riser 14, a manual diesel fuel supply switch 35 is installed in the form of an emergency STOP button, the contacts of which break the power supply circuit of the pump starter and which can be used for emergency shutdown of the fuel supply by turning off the pump.

Work of gas stations and TS "Field"

In the absence of a fueling station at the filling station and the loading unit of the Pole vehicle, the filling station operates as usual. In the area of a car fueling station 1 from the operator's 2, fueling is carried out for cars refueling under a canopy 3 from fueling columns 5, to which fuel is supplied from storage tanks for various types of fuel 4 through process pipelines 6. Replenishment of fuel reserves is carried out at the discharge site from the tank truck 7. The emergency tank 8 performs safety functions. Treatment facilities 9 provide wastewater treatment. The automatic control and management system 10, the system for measuring the fuel level in the tanks 11, the fire alarm 12 and the lightning protection and grounding system 13 provide their functions based on their purpose.

When the tanker 22 enters the zone of the gas station, the operator warns the loud speaker of the drivers about the termination of the release of petroleum products from the fuel dispensers 5 of the gas station. The territory of the nuclear power plant is being freed. The driver of the tanker 22 is earthing the body of the tanker 22. A barrier is lowered at the entrance to the gas station. The admission to the gas station of other cars is terminated. On the control panel, the power supply of the fuel dispensing columns of 5 filling stations is automatically switched off. The driver of the tanker 22 connects the plug of the sensors of the tanker 22 to the loading unit. The central control computer collects information about the state of the monitoring system monitoring sensors. A preliminary testing system for the availability of fuel 33 in the tanker 22 is started. The driver of the tanker 22 connects the flexible sleeves 15 for supplying diesel fuel and returning the gas phase to the tanker 22. A dose of diesel fuel is set on the central computer. Fuel is being loaded. The initial filling rate is not more than 1 m ³ / s. After filling the fuel to the level of overlapping of the filling pipe, the loading speed is increased to 2.8 m ³ / s. After filling 95% of the volume of the tanker, the speed automatically decreases to a limit of not more than 1 m ³ / s. Topping up to a given dose is performed. Dose control is performed by the flow meter. Automatically stop loading. When filling, the gas phase from the tanker 22 is sent to the storage tank 20. At the command of the controller, a valve 18 is opened, connecting the gas return pipe to the filling pipe. The remaining fuel in the riser, under gas pressure, merges into the tanker 22. Flexible sleeves 15 are disconnected from the tanker 22, the sensor plug is disconnected, the ground system is disconnected. Open the barrier, connect the fuel-dispensing columns of the gas station. The tanker 22 is driven away from the loading and unloading site. In the future, the gas station operates as usual for refueling cars and trucks with gasoline and diesel fuel.

Thus, the use of filling stations with TS "Pole" makes it possible to refuel cars and trucks with gasoline and diesel fuel at one station and to fill the tanks of small tankers with diesel engine fuel.

The application of the proposed NPP with the TS "Pole" will make it possible to bring the refueling points closer to the technological vehicles refueled with diesel fuel by providing refueling of passenger cars and trucks with gasoline and diesel fuel and filling small tanker tanks with diesel fuel.
