Description

Technical Field

[0001] This utility model belongs to the technical field of steam utilization devices, and in particular, it is a high-safety steam utilization device for oil refineries. Background Technology

[0002] Oil refineries generate steam containing a large amount of water during the refining process. Steam utilization devices can collect the steam and, after special treatment, continue to provide energy for the refinery's operations, thereby reducing the energy consumption caused by refining.

[0003] Existing high-safety steam recovery systems for oil refineries mostly recover excess steam by using the steam recovery unit and cooling and condensing the steam through cooling pipes and coolant. However, this recovery method directly wastes the heat of the steam. At the same time, the steam pressure in the steam recovery unit is uncontrollable. Therefore, if the steam pressure in the steam recovery unit is too high and not intervened in time, safety risks will occur. Therefore, there is an urgent need for a high-safety steam recovery system for oil refineries to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a highly safe steam utilization device for oil refineries to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-safety steam utilization device for oil refineries, comprising a steam recovery cylinder for oil refineries and a cooling pipe for crude oil transportation in oil refineries, wherein an oil inlet pipe and an oil outlet pipe are respectively connected to both sides of the side wall of the steam recovery cylinder, and both the oil inlet pipe and the oil outlet pipe are connected to the cooling pipe.

[0006] A steam recovery cylinder is connected to an outlet pipe on its side wall, and an installation pipe is connected to the end of the outlet pipe. A shielding cap is mounted above the installation pipe.

[0007] A sealing tube is fixedly installed inside the lower part of the mounting tube. The top surface of the sealing tube is arc-shaped, and the outer wall of the sealing tube is sealed to the inner wall of the mounting tube.

[0008] A horizontal plate is fixedly installed inside the upper part of the mounting tube. A push spring is fixedly installed at the bottom of the horizontal plate. A sealing valve is fixedly installed at the bottom of the push spring, and the bottom of the sealing valve matches the top surface of the sealing tube.

[0009] Preferably, a damping rod is fixedly installed at the bottom of the cross plate, and the telescopic end of the damping rod is fixedly installed on the top surface of the sealing valve.

[0010] Preferably, the damping rod is slidably sleeved inside the push spring.

[0011] Preferably, two limiting rods are symmetrically fixedly installed on the top surface of the sealing valve, and two limiting holes are longitudinally opened through the horizontal plate.

[0012] Preferably, the two limiting rods fixedly installed on the top surface of the sealing valve slide through the two limiting holes respectively.

[0013] Preferably, a rubber sealing gasket is fixedly bonded to the inner wall of the sealing tube.

[0014] Preferably, the cooling pipes are interconnected through multiple connecting pipes.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This highly safe refinery steam utilization unit benefits from the design of inlet pipes, outlet pipes, and cooling pipes. Crude oil is introduced into the interior of the cooling pipes through the inlet pipes, and then excess steam is recovered and introduced into the interior of the steam recovery cylinder, allowing the steam to fully contact the cooling pipes, thereby preheating the crude oil in the cooling pipes and accelerating the subsequent processing of the crude oil.

[0017] This highly safe steam recovery unit for oil refineries benefits from the design of its installation pipe, sealing pipe, horizontal plate, push spring, and sealing valve. The push spring pushes the bottom of the sealing valve, fixed at its end, to seal against the inside of the sealing pipe, thus sealing both the installation pipe and the sealing pipe. When the steam pressure inside the steam recovery cylinder is too high, the pressure pushes the sealing valve upwards, compressing the push spring and opening the sealing pipe to release the pressure inside the steam recovery cylinder. When the pressure inside the steam recovery cylinder returns to normal, the push spring pushes the sealing valve again to seal the sealing pipe, effectively preventing excessive pressure inside the steam recovery cylinder from causing safety risks.

[0018] This highly safe steam utilization device for oil refineries benefits from the design of damping rods and limit rods, which prevents the vibration generated by the push spring from directly affecting the sealing effect of the sealing valve on the sealing pipe. At the same time, the sliding through the horizontal plate by the two limit rods effectively improves the stability of the sealing valve during sliding.

[0019] This highly safe steam utilization device for oil refineries, compared with existing technologies, can automatically release excessive pressure in the steam recovery cylinder, while further improving the utilization of excess steam. Attached Figure Description

[0027] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0028] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0029] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0030] like Figures 1 to 4The main structure of a high-safety steam utilization device for oil refineries consists of a steam recovery cylinder 1 for oil refineries and a cooling pipe 11 for crude oil transportation in oil refineries. The side walls of the steam recovery cylinder 1 are respectively connected to an oil inlet pipe 2 and an oil outlet pipe 3, and both the oil inlet pipe 2 and the oil outlet pipe 3 are connected to the cooling pipe 11. Thanks to the structure of the oil inlet pipe 2, the oil outlet pipe 3 and the cooling pipe 11, the crude oil to be processed is introduced into the interior of the cooling pipe 11 through the oil inlet pipe 2. Then, the excess steam is recovered and introduced into the interior of the steam recovery cylinder 1, so that the steam can fully contact the cooling pipe 11, thereby preheating the crude oil in the cooling pipe 11 in advance, thus accelerating the subsequent processing of the crude oil.

[0031] A steam recovery cylinder 1 is connected to an exhaust pipe 4, and an installation pipe 5 is connected to the end of the exhaust pipe 4. A shielding cap 6 is installed above the installation pipe 5. Thanks to the shielding cap 6, the top of the installation pipe 5 can be effectively shielded, thereby preventing dust and debris from falling into the interior of the installation pipe 5 and affecting the normal operation of its internal components.

[0032] A sealing tube 7 is fixedly installed inside the lower part of the mounting tube 5. The top surface of the sealing tube 7 is arc-shaped, and the outer wall of the sealing tube 7 is sealed with the inner wall of the mounting tube 5. The bottom of the sealing valve 8 and the top surface of the sealing tube 7 are both arc-shaped, which can further increase the contact area between the sealing valve 8 and the sealing tube 7, thereby further improving the sealing effect between the sealing valve 8 and the sealing tube 7.

[0033] A horizontal plate 9 is fixedly installed horizontally at the top of the interior of the installation pipe 5. A push spring 10 is fixedly installed at the bottom of the horizontal plate 9. A sealing valve 8 is fixedly installed at the bottom of the push spring 10, and the bottom of the sealing valve 8 matches the top surface of the sealing pipe 7. Thanks to the structure of the installation pipe 5, the sealing pipe 7, the horizontal plate 9, the push spring 10, and the sealing valve 8, the bottom of the sealing valve 8 fixedly installed at its end can be pushed by the push spring 10 to seal against the interior of the sealing pipe 7, thereby sealing the installation pipe 5 and the sealing pipe 7. When the steam pressure in the steam recovery cylinder 1 is too high, the pressure will push the sealing valve 8 upward and compress the push spring 10, thereby opening the sealing pipe 7 and releasing the pressure in the steam recovery cylinder 1. When the pressure in the steam recovery cylinder 1 returns to the normal value, the push spring 10 will push the sealing valve 8 again to seal the sealing pipe 7, thereby effectively preventing the safety risks caused by excessive pressure in the steam recovery cylinder 1.

[0034] A damping rod 12 is fixedly installed at the bottom of the horizontal plate 9. The telescopic end of the damping rod 12 is fixedly installed on the top surface of the sealing valve 8. The damping rod 12 is slidably sleeved inside the push spring 10. Thanks to the setting of the damping rod 12, the vibration generated by the push spring 10 can be prevented from directly affecting the sealing effect of the sealing valve 8 on the sealing tube 7.

[0035] Two limiting rods 13 are symmetrically fixedly installed on the top surface of the sealing valve 8. Two limiting holes are longitudinally opened on the horizontal plate 9. The two limiting rods 13 fixedly installed on the top surface of the sealing valve 8 slide through the two limiting holes respectively. The sliding of the two limiting rods 13 through the horizontal plate 9 can effectively improve the stability of the sealing valve 8 when sliding, and at the same time limit the extension and retraction direction of the push spring 10.

[0036] A rubber sealing gasket 14 is fixedly bonded to the inner wall of the sealing tube 7. Thanks to the setting of the rubber sealing gasket 14, the sealing effect between the sealing tube 7 and the sealing valve 8 can be further improved.

[0037] The cooling pipe 11 is interconnected by multiple connecting pipes, which can further increase the contact area between the cooling pipe 11 and the steam, thereby further improving the heat exchange effect between crude oil and steam.

[0038] Working principle

[0039] This highly safe refinery steam utilization device operates by first introducing the crude oil to be processed through the inlet pipe 2 into the cooling pipe 11 installed inside the steam recovery cylinder 1. Simultaneously, excess steam from the refinery is introduced into the steam recovery cylinder 1, ensuring uniform and thorough contact between the cooling pipe 11 and the steam inside the steam recovery cylinder 1. This allows the crude oil to cool and condense the steam while simultaneously heating the crude oil, thus accelerating subsequent processing. When the steam pressure inside the steam recovery cylinder 1 becomes too high, the high-pressure steam pushes the sealing valve 8 upwards and compresses the push spring 10, simultaneously moving the sealing valve 8 away from the sealing pipe 7. This opens the sealing pipe 7 and releases the high-pressure gas, preventing safety risks to the steam recovery cylinder 1 due to high pressure. When the pressure inside the steam recovery cylinder 1 returns to a safe level, the push spring 10 pushes the sealing valve 8 again, tightly sealing it against the top surface of the sealing pipe 7.
