Description

Technical Field

[0001] This utility model belongs to the field of gas-liquid separation, and specifically relates to a multi-stage condensation structure for a gas-liquid separation device. Background Technology

[0002] Gas-liquid separation equipment is a device used to separate and remove moisture from gaseous media. Its core function is to reduce the gas temperature to below the dew point, causing the water vapor contained in it to condense into liquid water, thereby achieving gas-liquid separation through mechanical or physical means. If the gas-liquid separation equipment lacks a pretreatment stage and the condensation structure design does not consider reducing subsequent loads, it will lead to significant drawbacks. First, when high-temperature and high-humidity gas suddenly enters a single heat exchange tube, it will generate a severe instantaneous condensation load, causing thermal stress concentration on the surface of the heat exchange tube and making it easy to form a water film or water hammer phenomenon, which seriously reduces heat exchange efficiency and increases coolant energy consumption. At the same time, frequent load fluctuations may accelerate equipment corrosion and scaling, shorten equipment life and increase maintenance costs. Therefore, we hope to design a multi-stage condensation structure for gas-liquid separation equipment to solve this problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-stage condensation structure for a gas-liquid separation device, thereby solving the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a multi-stage condensation structure for a gas-water separation device, comprising: a condensation shell, a support base provided at the lower end of the condensation shell, and a secondary separation mechanism provided inside the condensation shell;

[0005] The condenser shell has an outlet and an inlet at its left and right ends, respectively. A secondary drain outlet is located on the lower left side of the condenser shell, and a pre-drain outlet is located on the lower right side of the condenser shell. A pre-separation section is also located on the right side of the condenser shell. By setting up the pre-separation section, the low-temperature cold quench gas that is finally discharged is introduced into the inlet pipe and tangentially sprayed, so as to pre-cool and dehumidify the high-temperature and high-humidity gas at the inlet using the residual cooling of the system itself. This significantly reduces the main cold source load and energy consumption of the subsequent condenser, while improving the overall dehydration efficiency and the economic operation of the equipment.

[0006] In a preferred embodiment, the pre-separation section includes a conveying pipe, the two ends of which are fixedly connected to the left and right ends of the condenser shell, respectively. A conveying fan is fixedly installed in the middle of the conveying pipe, and a cyclone separator is also provided inside the right end of the condenser shell.

[0007] In a preferred embodiment, the hydrocyclone is fixedly connected with a support plate in an evenly spaced circumference, and the other end of the support plate is fixedly connected to the inner surface of the condenser shell.

[0008] In a preferred embodiment, the secondary separation mechanism includes three partition plates, which are fixedly connected to the interior of the condenser shell. Several heat exchange tubes are fixedly sleeved inside the partition plates to increase the heat exchange area. By setting up a secondary separation mechanism, most of the high-boiling-point substances are first efficiently removed in the primary chamber using a higher-temperature coolant, and then the low-boiling-point components are deeply condensed in the secondary chamber using a low-temperature coolant. This significantly improves the condensation efficiency and separation purity, while avoiding the energy waste caused by single low-temperature cooling, significantly reducing the overall energy consumption of the system and enhancing its adaptability to complex gas compositions.

[0009] In a preferred embodiment, the heat exchange tube is a thin-walled spiral structure used to generate centrifugal force through gas swirling.

[0010] In a preferred embodiment, the heat exchange tube is made of a copper alloy with excellent thermal conductivity.

[0011] In a preferred embodiment, the three partition plates are linearly and equally distributed inside the condenser shell to form a primary heat exchange chamber and a secondary heat exchange chamber inside the condenser shell.

[0012] In a preferred embodiment, the upper outer side of the condenser shell is fixedly connected to two coolant inlets corresponding to the primary heat exchange chamber and the secondary heat exchange chamber, and the lower outer side of the condenser shell is fixedly connected to two coolant outlets corresponding to the primary heat exchange chamber and the secondary heat exchange chamber. The primary heat exchange chamber is located on the air inlet side, and the secondary heat exchange chamber is located on the air outlet side. In the coolant inlets, the inlet connected to the primary heat exchange chamber is supplied with a higher temperature coolant, and the coolant inlet connected to the secondary heat exchange chamber is supplied with a lower temperature coolant.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are:

[0014] 1. By setting up a pre-separation section, and using a swirling chamber in the inlet pipe to introduce the low-temperature cold quenching gas that is finally discharged for tangential injection, the residual cooling of the system can be used to pre-cool and dehumidify the inlet high-temperature and high-humidity gas, thereby reducing the instantaneous condensation load and improving the service life of the equipment. At the same time, it reduces the main cold source load and energy consumption of the subsequent condenser, and improves the overall dehydration efficiency and the economic efficiency of equipment operation.

[0015] 2. By setting up a two-stage separation mechanism, most of the high-boiling-point substances are first efficiently removed in the first-stage chamber using a higher-temperature coolant, and then the low-boiling-point components are deeply condensed in the second-stage chamber using a low-temperature coolant. This greatly improves the condensation efficiency and separation purity, while avoiding the energy waste caused by single low-temperature cooling, significantly reducing the overall energy consumption of the system and enhancing its adaptability to complex gas compositions.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 As the first embodiment of this utility model:

[0026] A multi-stage condensation structure for a gas-liquid separation device includes: a condensation shell 1, a support base 2 at the lower end of the condensation shell 1, and a secondary separation mechanism 3 inside the condensation shell 1.

[0027] The left and right ends of the condenser shell 1 are respectively provided with an air outlet 12 and an air inlet 11. The lower left end of the condenser shell 1 is provided with a secondary drain port 13, and the lower right end of the condenser shell 1 is provided with a pre-drain port 14. The right end of the condenser shell 1 is also provided with a pre-separation section 15. By setting the pre-separation section 15, the low-temperature cold quench gas that is finally discharged is introduced into the inlet pipe through a swirling chamber for tangential injection. The residual cooling of the system can be used to pre-cool and dehumidify the inlet high-temperature and high-humidity gas, thereby reducing the instantaneous condensation load and improving the service life of the equipment. At the same time, it reduces the main cold source load and energy consumption of the subsequent condenser, and improves the overall dehydration efficiency and the economic operation of the equipment.

[0028] The pre-separation section 15 includes a conveying pipe 151, with both ends of the conveying pipe 151 fixedly connected to the left and right ends of the condenser shell 1, respectively. A conveying fan 152 is fixedly installed in the middle of the conveying pipe 151, and a cyclone separator 153 is also provided inside the right end of the condenser shell 1.

[0029] A support plate is fixedly connected to the hydrocyclone 153 in a circumferentially divided manner, and the other end of the support plate is fixedly connected to the inner surface of the condenser shell 1.

[0030] Specifically, the gas to be separated is first transported to the interior of the condenser shell 1 through an external gas conveying device. Then, the gas passes through the hydrocyclone 153, where it is forced to rotate. Due to the density difference between the gas and liquid phases, centrifugal force causes the denser droplets to be thrown against the inner wall of the condenser shell 1 and initially aggregate, achieving primary separation of gas and liquid. The gas after initial separation continues to flow to the left, while the separated liquid settles downwards due to gravity and is discharged through the pre-drainage port 14 on the lower right side of the condenser shell 1. At the same time, the conveying fan 152 is started, and the cold air separated by the secondary separation mechanism 3 is conveyed to the right end of the condenser shell 1 through the conveying pipe 151. This achieves the purpose of using the residual cold air discharged to pre-treat the intake air, significantly reducing the main cold source load and energy consumption of the subsequent secondary separation mechanism 3, while improving the overall dehydration efficiency and equipment operating economy.

[0031] Please see Figures 1-3 As a second embodiment of this utility model:

[0032] The secondary separation mechanism 3 includes three partition plates 31, which are fixedly connected to the inside of the condenser shell 1. Several heat exchange tubes 32 are fixedly sleeved inside the partition plates 31 to increase the heat exchange area. By setting up the secondary separation mechanism 3, most of the high-boiling-point substances are first efficiently removed in the primary heat exchange chamber using a higher-temperature coolant, and then the low-boiling-point components are deeply condensed in the secondary heat exchange chamber using a low-temperature coolant. This greatly improves the condensation efficiency and separation purity, while avoiding the energy waste caused by single low-temperature cooling, significantly reducing the overall energy consumption of the system and enhancing the adaptability to complex gas compositions.

[0033] The heat exchange tube 32 is a thin-walled spiral structure used to generate centrifugal force through gas swirling.

[0034] The heat exchange tube 32 is made of a copper alloy with excellent thermal conductivity.

[0035] Three partition plates 31 are linearly and equally distributed inside the condenser shell 1 to form a primary heat exchange chamber 33 and a secondary heat exchange chamber 34 inside the condenser shell 1.

[0036] Two coolant inlets 35, corresponding to the primary heat exchange chamber 33 and the secondary heat exchange chamber 34, are fixedly connected to the upper outer side of the condenser housing 1. Two coolant outlets 36, corresponding to the primary heat exchange chamber 33 and the secondary heat exchange chamber 34, are fixedly connected to the lower outer side of the condenser housing 1. The primary heat exchange chamber 33 is located on the air inlet side, and the secondary heat exchange chamber 34 is located on the air outlet side. The coolant inlet 35 connected to the primary heat exchange chamber 33 is supplied with a higher temperature coolant, and the coolant inlet 35 connected to the secondary heat exchange chamber 34 is supplied with a lower temperature coolant.

[0037] Based on the above embodiments, the pretreated gas first enters the interior of the primary heat exchange chamber 33 through the heat exchange tube 32. The spiral structure of the heat exchange tube 32 induces the gas to swirl, and centrifugal force separates larger droplets to the wall of the heat exchange tube 32. At the same time, the gas exchanges heat with the coolant through the heat exchange tube 32, and some high-boiling-point components condense and precipitate due to cooling. Further, the gas enters the secondary heat exchange chamber 34 for deep processing. The temperature of the coolant in the secondary heat exchange chamber 34 is lower than that of the coolant in the primary heat exchange chamber 33. This lower-temperature coolant creates a stronger cooling environment. When the gas is induced to swirl again in this chamber, the lower-boiling-point components in the remaining gas phase are fully condensed and separated. Due to the temperature gradient between the two coolants, the effect of staged condensation is achieved, thereby improving the separation efficiency and purity. Finally, the cold gas after two-stage condensation and centrifugal separation is discharged from the heat exchange tube 32 and the outlet 12 at the left end of the condensing shell 1. The condensed liquid is collected and discharged from the secondary drain port 13 on the lower left side of the condensing shell 1.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
