Description

Technical Field

[0001] The present invention relates to the field of heat exchange technology, and in particular to an integrated, efficient, and intelligent heat exchange device for oil field stations. Background Art

[0002] After crude oil enters the oilfield station through the gathering pipeline, it first undergoes a primary gas-liquid separation process and is then heated for dehydration. During the heating and dehydration stage, the equipment used to heat the crude oil at the oilfield station is primarily a heat exchanger. A heat exchanger is a device that uses hot water or steam to transfer heat to the crude oil, using hot water or steam as the heat medium. Oilfield stations generally use hot water for heat exchange. Currently, most stations use manual shut-off valves for their heat exchangers. The heat exchange effect is then observed by measuring the inlet and outlet temperatures of the heat exchanger's hot and cold media. If the outlet temperature of the cold medium drops, the shut-off valve opening is increased to increase the hot medium flow rate and raise the outlet temperature of the cold medium. If the outlet temperature of the cold medium is too high, the shut-off valve opening is decreased to reduce the hot medium flow rate and lower the outlet temperature of the cold medium.

[0003] Manual operation of the stop valve consumes a lot of time and manpower, which is relatively inconvenient. When the crude oil enters the shell side of the heat exchanger for heat exchange, the flow-type heat exchange easily leads to low crude oil heat exchange efficiency. Increasing the contact time between the crude oil and the heat medium can fully exchange heat, but it will lead to a decrease in overall efficiency. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide an integrated, efficient and intelligent heat exchange device for oil field stations to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. The drive component drives the discs inside the nine groups of heat exchange cylinders to move back and forth, dividing the heat exchange cylinders into two parts, always keeping one part for oil inlet and the other part for oil outlet, thereby improving the efficiency of crude oil transportation. At the same time, the crude oil is sent into the heat exchange cylinders in batches to fully carry out heat exchange, thereby improving the effect of heat exchange.

[0006] Furthermore, the first oil delivery tank, the collecting tank and the heating water tank are separated by a certain distance, and connecting columns are fixed at the intervals between the first oil delivery tank, the collecting tank and the heating water tank. A first inlet pipe is fixed at the top of the first oil delivery tank, and a second inlet pipe is fixed at the top of the second oil delivery tank.

[0007] Furthermore, the drive assembly also includes a screw, which is rotatably installed on the outer wall of the heat exchange tube through a bearing seat, and the arc plate is threadedly sleeved on the screw. A drive motor is fixed on the top of one of the nine groups of heat exchange tubes, and the output end of the drive motor is fixedly connected to the screw.

[0008] Furthermore, a driving gear is fixed to the top of the screw, and a gear ring is meshed and connected to the periphery of the driving gear. The gear ring and the center of the second oil delivery tank are on the same axis. An axial ring is rotatably installed on the top of the second oil delivery tank, and vertical plates are equidistantly fixed on the top of the axial ring. The top of the vertical plate is fixedly connected to the gear ring.

[0009] Furthermore, contact blocks are fixed on the top and bottom of the arc plate, and contact switches are fixedly installed on the top and bottom of the outer wall of the heat exchange cylinder at positions corresponding to the contact blocks, and the contact blocks are alternately squeezed into contact with the two contact switches.

[0010] Furthermore, a first valve plate is rotatably installed inside the first delivery pipe and the second delivery pipe, and a second valve plate is rotatably installed inside the connecting pipe. The valve stem of the first valve plate passes through the first delivery pipe and the second delivery pipe and is fixed with a first bevel gear, and the valve stem of the second valve plate passes through the connecting pipe and is fixed with a second bevel gear, and the first bevel gear is meshed with the second bevel gear.

[0011] Furthermore, a connecting rod is rotatably installed on the other side of the first valve plate axis of the first delivery pipe and the second delivery pipe, and the connecting rod is fixedly connected to the valve stem of the first valve plate, and a transmission belt is installed between the two connecting rods.

[0012] Furthermore, a third valve plate is rotatably installed inside the inlet end of the U-shaped heat exchange tube, a shaft is fixed at the axis of the third valve plate, and a rotating plate is fixed at the inlet end of the U-shaped heat exchange tube when the shaft rotates and passes through the inlet end of the U-shaped heat exchange tube. The shaft is rotatably connected to the outer wall of the inlet end of the U-shaped heat exchange tube through a bearing and a torsion spring.

[0013] Furthermore, an electric push rod is fixed on the outer wall of the heating water tank at a position corresponding to the rotating plate, and an extrusion plate is fixed to the extended end of the electric push rod, and the extrusion plate is in extrusion contact with the rotating plate.

[0014] Furthermore, a temperature sensor is fixedly installed on the outer wall of the outlet end on the other side of the U-shaped heat exchange tube.

[0015] Beneficial effects of the present invention: In the present invention, when the first valve plate in the first delivery pipe is opened, the first valve plate in the second delivery pipe is closed, the second valve plate in the upper connecting pipe is in a closed state, and the second valve plate in the lower connecting pipe is in an open state. Therefore, the two parts of the heat exchange cylinder can be moved to respectively pump in crude oil and deliver the crude oil after heat exchange, thereby maintaining efficient crude oil transportation and improving the overall heat exchange efficiency.

[0016] The present invention retracts the extended end of the electric push rod, and the extrusion plate no longer contacts the rotating plate. The rotating plate and the shaft rod rotate under the action of the torsion spring, and the third valve plate automatically closes to intercept the heat medium in the U-shaped heat exchange tube, giving the crude oil and the heat medium time to fully exchange heat. When the arc plate moves again, the electric push rod drives the extrusion plate to squeeze the rotating plate, and then the shaft rod drives the third valve plate to rotate and open to continue transporting the heat medium. The heat medium after heat exchange returns to the heating water tank through the delivery end to continue heating. In this process, the temperature of the water flow is monitored by the temperature sensor at the outlet end. When the temperature is too low, the electric push rod continues to push the extrusion plate to move, and the rotation angle of the squeezed rotating plate becomes larger, and the opening angle of the third valve plate also becomes larger, thereby increasing the circulation of the heat medium. When the temperature at the outlet end is high, the opening of the third valve plate is reduced by the electric push rod to reduce the circulation of the heat medium.

[0017] The present invention drives the driving motor to rotate the driving gear and engage with the gear ring. The gear ring rotates along the top of the second oil delivery tank through the vertical plate and the shaft ring. The screws on the outside of the nine groups of heat exchange cylinders rotate synchronously. The arc plate cooperates with the screw threads to move vertically, driving the ring rope to reciprocate around the inside of the heat exchange cylinder and the traction disc to move, thereby realizing the pumping of crude oil and the push-out of crude oil after the heat exchange is completed.

[0018] Compared with the prior art, the present invention drives the discs inside the nine groups of heat exchange cylinders to move back and forth by means of a driving assembly, thereby dividing the heat exchange cylinders into two parts, and always keeping one part for oil inflow and the other part for oil outflow, thereby improving the efficiency of crude oil transportation. At the same time, the crude oil is fed into the heat exchange cylinders in batches to fully carry out heat exchange, thereby improving the effect of heat exchange. BRIEF DESCRIPTION OF THE DRAWINGS

The heat exchanger 51 is in a state of being ... At the time of exchange, when the arc plate 67 moves again, the electric push rod 55 drives the extrusion plate 56 to squeeze the rotating plate 54, and then the shaft 53 drives the third valve plate 52 to rotate and open, and continue to transport the heat medium. The heat medium after heat exchange returns to the inside of the heating water tank 3 through the delivery end to continue heating. In this process, the water flows through the outlet end and the temperature is monitored by the temperature sensor 57. When the temperature is too low, the electric push rod 55 continues to push the extrusion plate 56 to move, and the rotation angle of the squeezed rotating plate 54 becomes larger, and the opening angle of the third valve plate 52 also becomes larger, increasing the circulation of the heat medium. When the outlet temperature is high, the electric push rod 55 is used to reduce the opening of the third valve plate 52 to reduce the circulation of the heat medium, and the water source is added to the heating water tank 3 through the water supply pipe 31 outside the heating water tank 3.
