Description

Technical Field

[0001] The utility model belongs to the technical field of low-temperature storage of crude oil, and in particular relates to a solar-driven cold-storage type oil and gas storage composite system. Background Art

[0002] With the increasing efforts in the exploitation and utilization of oil and gas resources, the number of ground oil and gas storage facilities is increasing. In order to ensure the quality and safety of oil and gas during ground storage, constructing effective oil and gas storage conditions is the key to ensuring the safe and stable operation of oil and gas storage and transportation.

[0003] Existing storage methods for crude oil include ground storage tanks, salt caverns, and hard rock caverns. Due to the type, state, and carbon chain structure of crude oil, the conditions for storing crude oil are very strict. In order to ensure the quality of crude oil, the storage conditions such as temperature, air, moisture, sunlight, and metal should be strictly controlled during the storage process of crude oil. Among them, the control of temperature and humidity is particularly critical. Crude oil must be stored at low temperatures, and the low temperature environment required consumes a lot of energy. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to solve the problem of large energy consumption in the low-temperature environment required for low-temperature storage of crude oil in the prior art, a solar-driven cold storage type oil and gas storage composite system is provided.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a solar-driven cold storage type oil and gas storage composite system, including an oil storage chamber and a temperature and humidity adjustment system, wherein the temperature and humidity adjustment system includes a refrigeration device, a heating device, an atomization device and a solar device;

[0006] The refrigeration device comprises an adsorber, a condenser, a desorber, an ice storage device and a condensing device which are connected in sequence, the refrigerant inside the adsorber, the condenser and the desorber is calcium chloride ammonia, and the condensing device is located in the oil storage chamber;

[0007] The solar device includes a solar radiation receiver, a solar thermal collector connected to the output end of the solar radiation receiver and used to provide heat for the adsorber, and a photoelectric converter located inside the solar radiation receiver. The photoelectric converter converts solar energy into electrical energy for powering a refrigeration device, a heating device and an atomization device.

[0008] During the day, the solar radiation receiver receives sunlight, the solar thermal collector absorbs solar radiation and collects heat, and the heat is transferred to the adsorber, which continuously heats the working medium calcium chloride ammonia. The ammonia is desorbed by heat, and the desorbed ammonia vapor is condensed in the condenser. The condensed liquid ammonia enters the desorber under the action of gravity. At night, the solar radiation disappears, the adsorber is continuously cooled, and its internal temperature and pressure drop accordingly. When the pressure in the adsorber drops to the saturation pressure corresponding to the desorber temperature, the calcium chloride adsorbs the liquid ammonia in the desorber again, thereby producing an evaporative cooling effect. The cold source of the desorber condenses the working medium water in the ice storage device into ice, and the solid ice is sent to the condensing device located indoors, which provides stable cooling for the indoor environment driven by the temperature difference. In this cooling mode, the greater the temperature difference, the faster the cooling speed. By combining solar refrigeration with ice storage, the ice made by the solar refrigeration system at night is stored by the ice storage system, and during the day, it provides a cold source for the oil storage room.

[0009] The above technical solution converts solar energy into heat energy and light energy to provide a cold source for the oil storage room, which is environmentally friendly and energy-saving. The temperature and humidity inside the oil storage room can be adjusted by using a refrigeration device, a heating device and an atomization device, and the temperature and humidity in the storage room can be adjusted to the optimal storage range to maximize the quality and safety of oil and gas storage.

[0010] Furthermore, it also includes a dual gas conditioning system, which includes vortex ring suction nozzles arranged at the four corners of the top of the oil storage chamber, a pipeline arranged in a groove on the wall of the oil storage chamber and connected to the vortex ring suction nozzle at the tail, and a gas valve connected to the head of the pipeline. The inner wall of the pipeline is iron-adhered to a plastic isolation membrane. The gas valve is a spring diaphragm type and has five openings to control the pressure and flow of the gas entering the pipeline, so that the vortex ring suction nozzle can adjust the gas flow and pressure. The pipe wall of the pipeline is provided with air holes for balancing the air pressure. The output crude oil is squeezed by the elastic diaphragm to change the crude oil pressure of the output storage center. The crude oil flow of the output storage center is adjusted by the vortex ring suction nozzle to achieve dual gas conditioning of oil-gas flow and pressure.

[0011] The gas passes through the spring diaphragm to create disturbance inside the pipeline, and gradually forms a vortex ring after entering the vortex ring nozzle, causing a pressure difference between the inside and outside of the vortex ring nozzle and forming a siphon effect. The gas flow and pressure inside the oil storage chamber can be adjusted by adjusting the opening of the vortex ring nozzle and the siphon effect generated, thereby realizing "dual gas regulation" of indoor flow and pressure.

[0012] Furthermore, it also includes a venting system, which includes a small groove opened in a low-lying part of the oil storage chamber, a plurality of protrusions are provided at the bottom of the small groove, a first battery negative electrode is provided above the protrusions, a first battery positive electrode is buried in the soil below the small groove, a first venting pipeline is connected between the first battery positive electrode and the first battery negative electrode, and a first switch is provided on the first venting pipeline.

[0013] Furthermore, a large groove is provided below the small groove, the cross-sectional area of ​​the large groove is larger than that of the small groove, a plurality of protrusions are provided on the bottom of the large groove, a second battery negative electrode is provided above the protrusions, a second battery positive electrode is buried in the soil below the large groove, a second air venting pipeline is connected between the second battery positive electrode and the second battery negative electrode, and a second switch is provided on the second air venting pipeline.

[0014] Furthermore, baffles are provided above the small groove and the large groove.

[0015] Furthermore, waterproof membranes are attached to the inside of the small groove and the large groove.

[0016] Furthermore, both the first battery positive electrode and the second battery positive electrode contain Na2SO4·12H2O.

[0017] Furthermore, the temperature and humidity regulating system also includes an exhaust fan.

[0018] Furthermore, the photoelectric converter is a semiconductor photodiode arranged at the center of the solar light receiver.

[0019] Furthermore, the solar light receiver is in the shape of an open gourd, which includes a first layer, a second layer, a third layer and a bottom layer arranged in sequence from top to bottom, and a mounting frame whose position can be adjusted is provided at the bottom of the solar light receiver.

[0020] The beneficial effects of the utility model are:

[0021] 1. The utility model converts solar energy into heat energy and light energy to provide a cold source for the oil storage room, which is environmentally friendly and energy-saving. It also combines solar refrigeration with ice storage. The ice produced by the system at night is stored by the ice storage system and provides a cold source for the system during the day.

[0022] 2. The utility model uses a temperature and humidity adjustment system to adjust the temperature and humidity inside the oil storage room, and adjusts the temperature and humidity of the oil storage room to the optimal storage range to ensure the quality and safety of oil and gas storage to the greatest extent;

The utility model is advantageous in that a gas venting system is arranged in a low-lying part of the oil storage chamber, and the positive electrode of the battery, the negative electrode of the battery, and a gas venting pipeline are used to solve the gas collection problem in the oil storage chamber.

[0039] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0040] Embodiment 1:

[0041] like Figure 1-Figure 8 As shown, the utility model is a solar-driven cold storage type oil and gas storage composite system, comprising: an oil storage chamber 1, a temperature and humidity adjustment system 2, a dual air conditioning system 3 and a gas drainage system 4;

[0042] The oil storage chamber 101 is provided with a plurality of oil storage tanks 101;

[0043] The temperature and humidity adjustment system 2 includes a refrigeration device, a heating device 212, an atomization device 216, a solar device, a temperature sensor 214, a humidity sensor 215 and an exhaust fan 210;

[0044] The refrigeration device comprises an adsorber 206, a condenser 207, a desorber 209, an ice storage device 208 and a condensing device 211 which are connected in sequence. The refrigerant in the adsorber 206, the condenser 207 and the desorber 209 is calcium chloride ammonia. The condensing device 211 is located in the oil storage chamber, and a water collecting tank 217 is provided below the condensing device 211 for collecting condensed water. The water collecting tank 217 is connected to an atomizing device 216, and the atomizing device 216 provides humidified air for the room. The water collecting tank 217 is provided with a steam trap 218.

[0045] The solar energy device includes a solar light receiver 201, a solar collector 205 connected to the output end of the solar light receiver 201 and used to provide heat for the adsorber 206, and a photoelectric converter located inside the solar light receiver 201. The photoelectric converter is a semiconductor photodiode 233 arranged in the center of the solar light receiver 201. The semiconductor photodiode 233 includes a base 2336 for fixing on the solar light receiver 201, a substrate 2335 located on the base 2336, a vacuum area 2332, a photosensitive diode 2331 located in the vacuum area 2332, a positive electrode 2333 and a negative electrode 2334.

[0046] The solar light receiver 201 is in the shape of an open gourd, and includes a first layer 2011, a second layer 2012, a third layer 2013 and a bottom layer 2014 arranged in sequence from top to bottom. Light is respectively gathered on the first layer 2011, the second layer 2012, the third layer 2013 and the bottom layer 2014, and finally gathered on the semiconductor photodiode 233 in the central recessed position of the solar light receiver 201 through the refraction and emission of light. A mounting frame 2015 whose position can be adjusted is provided at the bottom of the solar light receiver 201. By adjusting the mounting frame 2015, the direction of the opening of the solar light receiver 201 can be changed, thereby making full use of sunlight.

[0047] After the solar light receiver 201 collects light, it converts the solar light into electric energy through the semiconductor photodiode 233 to generate current, and then stores the electric energy through the storage battery 202, and releases it according to the power demand of the terminal. The inverter 203 converts the DC power into AC power, which flows through the line to each device that needs power. According to the power demand of each device, the valve switch is controlled to meet the power demand of each device, thereby achieving the effect of energy saving and power saving. Electric energy is provided to adsorber 206 through valve 222, to condenser 207 through valve 223, to desorber 209 through valve 224, to ice storage device 208 through valve 225, to condensing device 211 through valve 226, to heating device 212 through valve 227, to temperature sensor 214 through valve 228, to humidity sensor 215 through valve 229, to sonic atomization device 216 through valve 230, to steam trap 21821 through valve 231, and to solar collector 205 through valve 232.

[0048] During the day, the solar light receiver 201 receives sunlight, and the solar thermal collector 205 absorbs solar radiation and collects heat. The heat is transferred to the adsorber 206, which continuously heats the working medium calcium chloride ammonia. The ammonia is desorbed by heat, and the desorbed ammonia vapor is condensed in the condenser 207. The condensed liquid ammonia enters the desorber 209 under the action of gravity. At night, the solar radiation disappears, and the adsorber 206 is continuously cooled, and its internal temperature and pressure drop accordingly. When the pressure in the adsorber 206 drops to the saturation pressure corresponding to the temperature of the desorber 209, the calcium chloride again adsorbs the liquid ammonia in the desorber 209, thereby producing an evaporative cooling effect. The cold source of the desorber 209 freezes the working medium water in the ice storage tank 208 into ice, and the solid ice is sent to the condensing device 211 located indoors, which provides stable cooling for the indoor environment driven by the temperature difference. In this cooling mode, the greater the temperature difference, the faster the cooling speed. By combining solar refrigeration with ice storage, the ice produced by the solar refrigeration system at night is stored by the ice storage system, and during the day, it provides a cold source for the oil storage room.

[0049] The working principle of temperature and humidity control system 2: Figure 1 As shown, when the temperature and humidity in the oil storage tank 101 are controlled, the temperature sensor 214 and the humidity sensor 215 are located in the oil storage tank 101 to sense the temperature and humidity changes inside the oil storage tank 101:

[0050] ① When the temperature inside the oil storage tank 101 is lower than the oil and gas storage temperature range in the tank, the temperature sensor 214 sends a command to operate the heating device 212, and at the same time reduces the ice supply to the desorber 209, gradually increasing the temperature inside the oil storage tank; when the humidity decreases during the temperature increase, the humidity sensor 215 sends a command, and the sonic atomization device 216 starts to humidify the oil storage chamber, and at the same time adjusts the temperature and humidity in the oil storage tank 101 to maintain a dynamic balance of the optimal storage temperature and humidity.

[0051] ② When the temperature inside the oil storage tank 101 is higher than the oil and gas storage temperature range in the tank, the temperature sensor 214 sends a command to increase the ice supply speed to the desorber 209, and provides stable cooling capacity for the oil storage tank 101 driven by the temperature difference, gradually reducing the temperature inside the oil storage tank 101; when the humidity increases during the temperature increase, the humidity sensor 215 sends a command, and the induced draft fan 210 starts to run, and the dry low-temperature gas can enter the room through the induced draft fan 210, and at the same time, the temperature and humidity in the oil storage tank 101 are adjusted to maintain a dynamic balance of the optimal storage temperature and humidity.

[0052] ③ When the humidity in the oil storage tank 101 is lower than the humidity range for oil and gas storage in the tank, the humidity sensor 215 sends a command and the sonic atomization device 216 operates to gradually increase the humidity in the tank to the optimal storage range.

[0053] ④ When the humidity in the oil storage tank 101 is higher than the humidity range of the oil and gas storage in the tank, there are two humidity adjustment methods.

[0054] Solution I: The humidity sensor 215 sends a command, and the exhaust fan 210 starts to operate, so that the air in the oil storage tank 101 and the air in the oil storage chamber 1 exchange gas, and the humidity in the oil storage tank 101 is adjusted to within the optimal storage humidity range.

[0055] Solution II: The humidity sensor 215 sends a command, the heating device 212 heats the low-temperature gas entering the heating chamber 220 through the induced ventilator 210 to form heated gas, and the heated gas is sent to the refrigeration chamber 219. The condensing device 211 cools and condenses the heated gas to condense the steam in the heated gas into water to form dry low-temperature gas. The dry gas enters the oil storage tank 101 through the induced ventilator 210, and the gas with high humidity in the oil storage tank 101 is discharged to the outdoors through the gas external circulation pipe 213, completing the temperature and humidity adjustment.

[0056] The dual gas conditioning system 3 comprises a vortex ring suction nozzle 301 arranged at the four corners of the top of the oil storage chamber 1, a pipeline 303 arranged in a groove 302 on the wall of the oil storage chamber and connected to the vortex ring suction nozzle 301 at the tail, and a gas valve 306 connected to the head of the pipeline 303. A plastic isolation film 305 is attached to the inner wall of the pipeline 303. The gas valve 306 is a spring diaphragm type to control the pressure and flow of the gas entering the pipeline 303, so that the vortex ring suction nozzle 301 can adjust the gas flow and pressure. The pipe wall of the pipeline 303 is provided with a gas hole 304 for balancing the air pressure.

[0057] The gas passes through the spring diaphragm to form a disturbance inside the pipeline 303, and gradually forms a vortex ring after entering the vortex ring suction nozzle 301, which causes a pressure difference between the inside and outside of the vortex ring suction nozzle 301 and forms a siphon effect. By controlling the opening adjustment of the vortex ring suction nozzle 301 and applying its siphon effect, the gas flow and pressure inside the oil storage chamber can be adjusted, thereby realizing "double gas regulation" of the indoor flow and pressure.

[0058] Working principle of dual gas conditioning system 3: In actual operation, combined with Figure 2 and Figure 3 When the oil storage chamber 1 is gas-regulated, when the gas pressure exceeds the allowable pressure range of the oil storage tank 101, the gas valve 306 gradually opens, and the greater the gas pressure, the greater the opening of the gas valve 306; when the gas pressure is lower than the allowable pressure range of the oil storage tank 101, the opening of the gas valve 306 reaches the minimum, and the amount of gas output from the pipeline 303 through the gas valve 306 is smaller, and the gas in the pipeline 303 enters the vortex ring suction nozzle 301 through the flow pipeline 303. The vortex ring suction nozzle 301 controls the opening according to the different gas components and proportions inside the oil storage chamber 1 to control the amount of gas output from the oil storage chamber 1.

[0059] like Figure 6 As shown, the opening of the vortex ring suction nozzle 301 is divided into five levels to control the gas flow rate. When the oil and gas molecule content in the oil storage chamber 1 meets the requirements, the vortex ring suction nozzle 301 is closed. When the oil and gas molecule content in the oil storage chamber 1 is slightly lower than the ideal value, the vortex ring suction nozzle 301 is opened to gear II to gradually change the internal gas composition of the oil storage chamber 1. When the oil and gas molecule content inside the oil storage chamber is too high, the vortex ring suction nozzle 301 is opened to gears IV and V to reduce the internal gas of the oil storage chamber 1. When the oil and gas molecule content gradually reaches the expected value, the opening of the vortex ring suction nozzle 301 is changed to gear II to gradually reduce the internal gas composition of the oil storage chamber 1 so that the internal gas composition of the oil storage chamber 1 meets the requirements.

[0060] The degassing system 4 includes a small groove 410 opened in the low-lying part of the oil storage chamber, a plurality of first protrusions 408 are provided at the bottom of the small groove 410, a first battery negative electrode 405 is provided above the first protrusion 408, a first battery positive electrode 406 is buried in the soil below the small groove 410, a first degassing pipeline 401 is connected between the first battery positive electrode 406 and the first battery negative electrode 405, and a first switch 403 is provided on the first degassing pipeline 401.

[0061] A large groove 413 is provided below the small groove 410, and the cross-sectional area of ​​the large groove 413 is larger than that of the small groove 410. A plurality of second protrusions 408 are provided at the bottom of the large groove 413, and a second battery negative electrode 411 is provided above the second protrusion 408. A second battery positive electrode 412 is buried in the soil below the large groove 413, and a second air venting pipeline 402 is connected between the second battery positive electrode 412 and the second battery negative electrode 411, and a second switch 404 is provided on the second air venting pipeline 402.

[0062] Baffles 407 are provided above the small groove 410 and the large groove 413, and waterproof membranes that can pass cations and gases but not water are attached inside the small groove 410 and the large groove 413. The first battery positive electrode 406 and the second battery positive electrode 412 both contain Na2SO4·12H2O inside. When the internal temperature is too high, they change color and need to be replaced every 15 days.

[0063] The working principle of the ventilation system 4 is as follows: Figure 4 and Figure 5As shown, when there is a small amount of leakage in the oil storage chamber 1, the oil gradually flows into the small groove 410 and flows into the inner wall of the first battery negative electrode 405. The shear stress and shear stress generated by the oil hitting the baffle 407 and the protrusion 408 hit the first battery negative electrode 405 and produce a small deformation. The oil hits the inner wall of the first battery negative electrode 405 to produce a water hammer effect. The first battery negative electrode 405 is subjected to external force to produce a chemical reaction and form an electron flow that is transmitted to the first battery positive electrode 406. The soil microbial activity produces a chemical reaction inside to form an electric current. At this time, the first gas drainage pipeline 401 is started, and the collected gas is discharged from the oil storage chamber; when the oil and gas in the oil storage chamber leaks too much After a long time, the oil overflows from the small groove 410 and flows into the large groove 413 below the small groove 410. The shear stress and shear stress generated by the oil hitting the baffle 407 and the protrusion 408 hit the second battery negative electrode 411, causing the second battery negative electrode 411 to produce a slight deformation. The second battery negative electrode 411 undergoes a chemical reaction under the external force and forms an electron flow that is transmitted to the second battery positive electrode 412, which is subjected to the activity of soil microorganisms to produce a chemical reaction inside to form an electric current. At this time, the second air venting pipeline 402 is started, and the collected gas is discharged from the oil storage chamber. Reducing the collected gas can reduce the emission of oil and gas, improve the utilization efficiency of oil products, and also reduce environmental pollution.
