Description

Technical Field

[0001] This utility model relates to the field of oil and gas storage and transportation technology, specifically to an intelligent temperature control device for oil and gas storage and transportation. Background Technology

[0002] Crude oil or other petroleum products are flammable and explosive. Oil storage tanks are containers for storing crude oil or other petroleum products produced by chemical enterprises. Oil storage tanks are usually welded from steel plates. In summer, oil storage tanks are exposed to sunlight for a long time, and the temperature of the tank body is extremely high. The temperature inside the tank can reach more than 60 degrees Celsius. The high temperature causes a large amount of volatile oil vapor to accumulate at the top of the tank, which can easily cause safety hazards and requires cooling treatment.

[0003] According to a search report from a novelty search agency, announcement number CN212607117U discloses a remotely controllable cooling oil storage tank for oil and gas storage and application. The tank includes a tank body, an overpressure vent valve, an inlet pipe, an outlet pipe, a maintenance cover, lifting lugs, and a base. Its structure is simple, enabling remote data transmission, remote cooling control, and easy disassembly and cleaning of components. During use, temperature sensors, pressure sensors, and a data transceiver work together to achieve remote data transmission. Remote cooling control is achieved through the data transceiver, controller, and electrically controlled valve. The overpressure vent valve is designed with an venting end and a fixed end, facilitating disassembly and cleaning. This novel device saves significant manpower, reduces production risks, and improves production efficiency.

[0004] The aforementioned technology discloses a remotely controllable cooling oil storage tank for oil and gas storage. It uses a temperature sensor to detect the oil temperature and is equipped with a refrigerant injection port and a refrigerant discharge port for manual operation to inject refrigerant and regulate the temperature. However, it has the following shortcomings: 1. It requires manual operation to inject refrigerant for cooling; it cannot intelligently and automatically regulate the oil temperature, resulting in unsatisfactory automation and timeliness; 2. It lacks a vibration-damping support structure for transportation, leading to lower safety during oil and gas storage and transportation. Therefore, this application proposes an intelligent temperature regulation device for oil and gas storage to address the aforementioned problems. Utility Model Content

[0037] like Figures 1 to 3 As shown in this embodiment, an intelligent temperature control device for oil and gas storage and utilization includes:

[0038] An outer tank 1 has an inner liner 101 fixedly installed on its inner side.

[0041] The overpressure exhaust valve 105 is embedded and fixed to the top left side of the outer tank 1 and communicates with the top left side of the inner liner 101.

[0042] The vibration isolation support assembly is connected and fixed at equal intervals to the bottom of the outer tank 1. The vibration isolation support assembly is used to support the outer tank 1 when it is installed and fixed on the transport vehicle and to perform auxiliary vibration isolation work when transported.

[0043] Cooling system, including:

[0044] Cooling water tank 3 is fixed to the top of the outer tank 1 and filled with cooling water.

[0045] Water pump 301, the water inlet of water pump 301 is connected to the bottom right side of cooling water tank 3;

[0046] The internal and external water cooling components are installed on both the outside and inside of the inner tank 101, and their water inlet is connected to the water outlet of the water pump 301.

[0047] The dual-adjustable cooling water assembly connects the right end of the internal and external water cooling assembly to the top left side of the cooling water tank 3. The internal and external water cooling assembly is used to supply cooling water flow to simultaneously cool the inner and outer sides of the inner tank 101 when the water pump 301 is started.

[0048] The intelligent control module includes:

[0049] PLC controller 4 is fixed to the top of the outer tank 1 and electrically connected to the battery. The dual-adjustment cooling water assembly is used to return the cooling water that flows to the cooling water tank 3, and is controlled by PLC controller 4 to cool the returning cooling water.

[0050] Temperature sensor 402 is embedded and fixed on the top of inner liner 101, with the detection end extending into the interior of the inner liner.

[0051] The dual-adjustment chilled water assembly, temperature sensor 402, and water pump 301 are all electrically connected to the PLC controller 4 to achieve closed-loop control of water temperature and flow rate.

[0052] Specifically, the vibration isolation support assembly includes a T-shaped support 2. The top of the T-shaped support 2 is set with a concave arc structure and is fixedly connected to the same arc-shaped vibration isolation pad 201 between the front bottom, rear bottom and bottom of the outer tank 1. The T-shaped support 2 and the arc-shaped vibration isolation pad 201 cooperate to support the outer tank 1 at the bottom. After the T-shaped support 2 is installed and fixed on the transport vehicle, the arc-shaped vibration isolation pad 201 is used to assist in vibration isolation of the outer tank 1 during storage and transportation.

[0053] Furthermore, the internal and external water cooling assembly includes an outer copper coil 302 wound around the outside of the inner tank 101. One end of the outer copper coil 302 extends to the top of the outer tank 1 and is connected and fixed to the outlet of the water pump 301 through a right-angle pipe head. The other end of the outer copper coil 302 extends into the inner tank 101 and is connected and fixed to an inner copper coil 303. One end of the inner copper coil 303 is connected and fixed to an L-shaped pipe 304. Both the outer tank 1 and the inner tank 101 are fixed. The outer copper coil 302, inner copper coil 303 and L-shaped tube 304 are fixedly installed on the L-shaped tube 304. The water pump 301 draws cooling water from the cooling water tank 3 and pumps it into the outer copper coil 302. The cooling water then flows into the inner copper coil 303 and then flows out through the L-shaped tube 304. The cooling water absorbs heat and cools the inner and outer sides of the inner tank 101 simultaneously when it flows through the outer copper coil 302 and inner copper coil 303.

[0054] Furthermore, the dual-adjustment cooling water assembly includes a radiator 305 and a small chiller 306 fixedly installed on the top of the outer tank 1. The right end of the L-shaped pipe 304 is connected and fixedly connected to the inlet of the radiator 305, the outlet of the radiator 305 is connected and fixedly connected to the inlet of the small chiller 306, and the outlet of the small chiller 306 is connected and fixedly connected to the top left side of the cooling water tank 3. The small chiller 306 is electrically connected to the PLC controller 4. The radiator 305 and the small chiller 306 work together, and the PLC controller 4 presets the temperature value to control the opening and closing of the small chiller 306. The temperature sensor 402 detects the oil temperature inside the inner tank 101 in real time and transmits the temperature value to the PLC controller 4. The temperature value is set to three equal values. In the first low level, the PLC controller 4 controls only the water pump 301 to start. In the intermediate level, the PLC controller 4 controls the small chiller 306 to start. In the first low level, the water discharged through the L-shaped pipe 304 enters the radiator 305 for heat dissipation, and then is returned to the cooling water tank 3 through the small chiller 306 for recycling, performing initial cooling. When the temperature reaches the intermediate level, the PLC controller 4 controls the small chiller 306 to automatically start and further cool the cooling water flowing inside, so as to ensure the application effect of the cooling water and achieve further cooling effect. This realizes the effect of intelligent and automatic temperature adjustment according to the level when the oil temperature is high, reducing the risk of safety hazards caused by high temperature.

[0055] Furthermore, a high-temperature alarm 401 is fixed and electrically connected to the top of the PLC controller 4. The PLC controller 4, the high-temperature alarm 401, the water pump 301, the small chiller 306, and the temperature sensor 402 are all electrically connected to the battery. The high-temperature alarm 401 is activated by the PLC controller 4 to alert personnel when the temperature reaches the set high third level.

[0056] The usage method of this embodiment is as follows: When using the intelligent temperature control device for oil and gas storage, the insulation layer 5 is used to insulate the inner tank 101, reducing the internal oil temperature rise rate. The start and stop temperature values ​​of the water pump 301, the small chiller 306, and the audible and visual alarm 401 are preset using the PLC controller 4. These temperature values ​​are set to three levels: the lowest level (first level) is set to allow the PLC controller 4 to only control the water pump 301 to start; the intermediate level is set to allow the PLC controller 4 to control the small chiller 306 to start; and the highest level (third level) is set to allow the PLC controller 4 to control the small chiller 306 to start. Controller 4 activates the audible and visual alarm 401. Temperature sensor 402 monitors the oil temperature inside the inner tank 101 in real time and transmits the temperature value to PLC controller 4. When the temperature reaches the first low level, PLC controller 4 first starts the water pump 301. The water pump 301 draws cooling water from the cooling water tank 3 and pumps it into the outer copper coil 302. The cooling water then flows into the inner copper coil 303, and then flows out through the L-shaped pipe 304 to the radiator 305 for heat dissipation. Finally, it is returned to the cooling water tank 3 through the internal cooling system 306 for recycling. The radiator 305 provides initial cooling for the cooling water and utilizes the circulating cooling water to simultaneously absorb heat and lower the temperature of the inner tank 101, achieving the effect of cooling and regulating the oil temperature. When the oil temperature reaches the intermediate level, the PLC controller 4 automatically activates the small chiller 306 to further cool the circulating cooling water, ensuring the effectiveness of the cooling water application and achieving further cooling through the circulating cooling water. When the temperature reaches the high third level, the PLC controller 4 activates the audible and visual alarm 401 to alert personnel, achieving intelligent and automatic graded cooling and temperature regulation when the oil temperature is high, reducing the risk of safety hazards caused by high temperatures, eliminating the need for manual temperature adjustment, and improving the automation and timeliness of cooling. When the cooling water lowers the oil temperature below the low first level, the PLC controller 4 shuts down the water pump 301 and the small chiller 306, waiting for the temperature to rise again before resuming intelligent and automatic graded cooling. In addition, the high-temperature alarm alert allows personnel to be notified in time to take measures such as avoiding light, further improving safety during use.

[0057] After the T-shaped support 2 is installed and fixed on the transport vehicle, the T-shaped support 2 and the arc-shaped vibration isolation pad 201 are used to support the outer tank 1 at the bottom. When vibration occurs during storage and transportation, the arc-shaped vibration isolation pad 201 is used to assist in vibration isolation of the outer tank 1, so as to achieve the effect of vibration isolation support and protection during transportation and improve the safety of oil and gas storage and transportation.

[0058] The PLC controller 4, temperature sensor 402, water pump 301, small chiller 306, and audible and visual alarm 401 in this utility model are well known to those skilled in the art and belong to conventional methods or common knowledge. Those skilled in the art can arbitrarily select and match them according to their needs or convenience. In addition, the PLC controller 4 receives the temperature value transmitted by the temperature sensor 402 and controls the water pump 301, small chiller 306, and audible and visual alarm 401 to start according to the control temperature value set in the grade. This is a basic numerical control parameter setting control method well known to those skilled in the art. All of these belong to conventional methods or common knowledge of programmed numerical control and will not be described in detail here.

[0059] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
