Description

Technical Field

[0001] This utility model relates to the field of petroleum volatile gas treatment technology, and in particular to a petroleum volatile gas cooling and purification device. Background Technology

[0002] Petroleum volatile gas cooling and purification devices are environmentally friendly equipment used to treat volatile organic compounds generated during oil extraction, storage, or transportation. These devices use cooling and purification technologies to condense and recover the volatile oil and gas while removing impurities, achieving resource recovery and ensuring that exhaust gases meet emission standards. However, existing petroleum volatile gas cooling and purification devices still have the following drawbacks:

[0003] Traditional condenser components have limited contact area, resulting in insufficient contact between volatile gases and the condenser surface, leading to low condensation efficiency and incomplete liquefaction and recovery of some oil and gas. Secondly, condensed droplets easily adhere to the surfaces of pipes or heat exchangers, forming a liquid film that hinders subsequent heat exchange, further reducing efficiency and sometimes requiring shutdown for cleaning. Furthermore, existing filtration systems are typically complex in design, with inconvenient filter removal, allowing particulate impurities to easily clog filters or enter the condenser unit, causing equipment wear or scaling and increasing maintenance costs. Overall, traditional technologies may be insufficient in terms of energy efficiency, ease of maintenance, and automation, making them unsuitable for handling high-impurity or high-flow-rate volatile gases, and requiring further improvement.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3 As shown, a petroleum volatile gas cooling and purification device is disclosed, comprising a base plate 1, a cooling box 2 fixed on the upper surface of the base plate 1, a second air inlet pipe 3 and an air outlet pipe 4 fixed at the bottom and top of the side wall of the cooling box 2 respectively, a pre-filter assembly 5 fixedly installed on the side of the second air inlet pipe 3 away from the cooling box 2, a rotatable condenser assembly 6 disposed inside the cooling box 2, a chiller 7 fixed on the other side of the upper surface of the base plate 1, a drain pipe 71 and a return pipe 72 fixed at the outlet and inlet of the chiller 7 respectively, both the drain pipe 71 and the return pipe 72 being connected to the condenser assembly 6, and a motor 8 for driving the condenser assembly 6 to rotate installed on the upper surface of the base plate 1 and below the cooling box 2.

[0023] The pre-filter assembly 5 includes a filter cartridge 51 fixedly connected to the second air intake pipe 3, and a first air intake pipe 52 fixed to the other side of the top of the filter cartridge 51. A filter screen 55 is horizontally arranged inside the filter cartridge 51, and the filter screen 55 is located between the first air intake pipe 52 and the second air intake pipe 3.

[0024] In this embodiment, the first air inlet pipe 52 is connected to the petroleum volatile gas pipeline. After the volatile gas enters the filter cartridge 51 from the first air inlet pipe 52, it flows downward and passes through the filter screen 55. The filter screen 55 intercepts particulate impurities in the volatile gas, and the particulate impurities remain on the upper surface of the filter screen 55.

[0025] The top of the filter cartridge 51 is open, and a vertical rod 54 is fixed on the upper surface of the filter screen 55. A top cover 53 is fixedly connected to the top of the vertical rod 54, and the top cover 53 is fixedly connected to the filter cartridge 51 by bolts.

[0026] Therefore, the top cover 53 can be disassembled from the filter cartridge 51. After unscrewing the bolts on the top cover 53, the top cover 53 can be disassembled upwards. The filter screen 55 can be pulled out from the top of the filter cartridge 51 through the vertical rod 54, which is convenient for cleaning particulate impurities on the surface of the filter screen 55.

[0027] The condenser assembly 6 includes several vertically arranged vertical pipes 61. The bottom and top ends of the vertical pipes 61 are fixedly connected to two discs 62, and the discs 62 are hollow inside. The middle part of the two discs 62, which are far apart from each other, is respectively fixed with an inlet pipe 63 and an outlet pipe 64. The inlet pipe 63 passes through the bottom wall of the cooling box 2 and is rotatably connected to the cooling box 2 through a bearing. The bottom end of the inlet pipe 63 is rotatably connected to the drain pipe 71 through a sealed bearing. The outlet pipe 64 passes through the top wall of the cooling box 2 and is rotatably connected to the cooling box 2 through a bearing. The top end of the outlet pipe 64 is rotatably connected to the return pipe 72 through a sealed bearing.

[0028] In this embodiment, the chiller 7 adopts existing technology, and the specific model is not limited. The water cooled by the chiller 7 enters the bottom disc 62 through the drain pipe 71 and the inlet pipe 63, then passes through several vertical pipes 61, and enters the upper disc 62. Finally, it returns to the chiller 7 along the outlet pipe 64 and the return pipe 72 for recooling. In this way, the volatile gas entering the cooling box 2 will condense into liquid on the surface of the disc 62 and the vertical pipes 61, realizing the recovery of volatile gas.

[0029] A drive gear 81 is fixed at the output end of the motor 8, and a driven gear 65 is fixed on the surface of the water inlet pipe 63. The driven gear 65 meshes with the drive gear 81.

[0030] A drain pipe 9 is fixedly connected to the bottom wall of the cooling tank 2.

[0031] Under the meshing transmission of the driving gear 81 and the driven gear 65, the motor 8 can drive the water inlet pipe 63 to rotate, thereby driving the overall condensation assembly 6 to rotate inside the cooling tank 2, shaking off the condensed liquid. The shaken-off liquid is discharged from the drain pipe 9.

[0032] Activated carbon 10 is installed in the middle of the gas outlet pipe 4. A small amount of volatile gas after condensation is discharged through the gas outlet pipe 4 and adsorbed by the activated carbon 10.

[0033] In this embodiment, a controller (not shown in the figure) is also provided on the upper surface of the base plate 1. The controller model can be an S7-1200 series CPU 1214C (6ES7214-1BG40-0XB0). The motor 8 can be controlled by the controller.

[0034] Working principle: The chiller 7 is started, causing chilled water to circulate between the chiller 7 and the condenser assembly 6. Simultaneously, the motor 8 is started, driving the condenser assembly 6 to rotate. Petroleum vapors entering through the first inlet pipe 52 are filtered by the filter screen 55 and then enter the cooling tank 2. The vapors condense into liquid on the surface of the condenser assembly 6 and are thrown off under centrifugal force, finally exiting through the drain pipe 9 at the bottom of the cooling tank 2. After recovery, a small amount of vapors enters the outlet pipe 4 and is filtered by the activated carbon 10 before being discharged.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
