Description

Technical Field

[0001] This utility model relates to the field of marine environmental protection and energy conservation technology, and in particular to a low-temperature condensation and recovery device for volatile organic compounds in ships. Background Technology

[0002] Volatile organic compounds (VOCs) emitted from ships come from a wide range of sources, including fuel consumption, coatings and corrosion protection, and maintenance and cleaning. Their emissions not only cause air pollution but also affect the health of crew members. Current treatment methods utilize the differences in saturated vapor pressure of VOC components at different temperatures through cryogenic condensation devices. By gradually cooling the VOCs, they are condensed into a liquid state, thereby achieving separation and recovery.

[0003] When the marine volatile organic compound (VOC) cryogenic condensation and recovery unit is in operation, the ship's exhaust gas containing VOCs is first introduced into the unit. The refrigeration components within the unit quickly activate, and through a series of refrigeration cycles, the temperature is drastically reduced below the dew point of the VOCs. In this low-temperature environment, the vapor pressure of the originally gaseous VOCs drops significantly, leading to condensation and transformation from a gaseous to a liquid state. Subsequently, a specialized gas-liquid separation component separates the liquefied organics from the remaining gas. The separated liquid VOCs are collected and stored in a specific container for recovery, while the purified gas can be discharged into the atmosphere according to environmental standards.

[0004] In existing technologies, when VOCs are mixed with non-condensable gases such as air, some shipboard low-temperature condensation and recovery devices occupy the effective heat exchange space, resulting in low heat exchange efficiency and reduced VOCs treatment efficiency. Therefore, a shipboard low-temperature condensation and recovery device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a low-temperature condensation and recovery device for volatile organic compounds (VOCs) in ships, which aims to improve the problem in the prior art where non-condensable gases such as air occupy the effective heat exchange space when VOCs are mixed with them, resulting in low heat exchange efficiency and reduced VOCs treatment efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A low-temperature condensation and recovery device for volatile organic compounds (VOCs) in ships includes a base plate, a cooling chamber fixedly connected to the top of the base plate, a filter chamber fixedly connected to the top of the cooling chamber, two filter plates fixedly connected to the inner wall of the filter chamber, a cleaning mechanism fixedly connected to the left side of each of the two filter plates, a conveying pipe fixedly connected to the right side of the filter chamber, a compression mechanism fixedly connected to the right side of the conveying pipe, a temperature display meter fixedly connected to the top of the cooling chamber, the cleaning mechanism including two fixed plates, the right sides of the two fixed plates fixedly connected to the left side of the two filter plates, upper magnetic magnets fixedly connected to the bottom of the two fixed plates, multiple guide plates fixedly connected to the inner wall of the filter chamber, a cleaning plate slidably connected to the adjacent side of every two guide plates, a lower magnetic magnet fixedly connected to the top of the cleaning plate, multiple telescopic rods fixedly connected to the bottom inner wall of the filter chamber, each of the multiple telescopic rods having a spring on its exterior, and shielding components for limiting the magnetic magnets fixedly connected to the front and rear sides of the filter chamber.

[0008] The above scheme involves: the filter chamber performing preliminary filtration of the exhaust gas; the filter plates filtering out solids from the exhaust gas; the upper and lower magnetic magnets causing the cleaning plate to clean the filter plates; the transmission pipeline receiving the filtered exhaust gas; and the exhaust gas entering the cooling chamber for cooling after passing through the compression mechanism.

[0009] As a further description of the above technical solution:

[0010] The compression mechanism includes a housing, the left side of which is fixedly connected to the right side of the conveying pipe, and power blocks are fixedly connected to both the front and rear sides of the housing. Extrusion cooling plates are fixedly connected to the adjacent sides of the two power blocks. A connecting pipe is fixedly connected to the inner wall of the housing, and a collection component for collecting cooling water after extrusion in the exhaust gas is fixedly connected to the bottom of the connecting pipe.

[0011] The above scheme involves the compression mechanism squeezing and cooling the exhaust gas entering the connecting pipe by the electric block against the extrusion cooling plate, causing the moisture in the exhaust gas to separate and be converted into water.

[0012] As a further description of the above technical solution:

[0013] The shielding assembly includes multiple electric push plates, with adjacent sides of the multiple electric push plates fixedly connected to the front and rear sides of the base plate. A force-applying rod is fixedly connected to the drive end of each electric push plate, and a blocking plate is fixedly connected to the rear side of the force-applying rod.

[0014] The above scheme involves moving the electric push plate to make the blocking plate block the upper magnetic magnet. With its own insulation, the upper and lower magnetic magnets lose their magnetic attraction.

[0015] As a further description of the above technical solution:

[0016] The collection assembly includes a collection tank, a recycling tank is fixedly connected to the bottom of the collection tank, and two guide plates are fixedly connected to the inner wall of the recycling tank. A connecting plate is slidably connected to the adjacent side of the two guide plates.

[0017] The above scheme involves a collection tank that collects water from the connecting pipe, and the collected water eventually enters a recycling tank. A guide plate guides the connecting plate, allowing it to move in a straight line.

[0018] As a further description of the above technical solution:

[0019] The bottom of each of the two connecting plates is fixedly connected to a telescopic rod 2, and the outside of each of the two telescopic rod 2 is provided with a spring 2;

[0020] The above solution involves both the telescopic rod and the spring, which buffer the force applied to the connecting plate, thus slowing down its movement.

[0021] As a further description of the above technical solution:

[0022] A force-bearing plate is fixedly connected to one of the adjacent sides of the two connecting plates, and a telescopic plate is fixedly connected to the bottom of the force-bearing plate;

[0023] Through the above scheme: the force plate receives the weight of the water and thus moves downwards, while the telescopic plate protects the telescopic rod and the spring.

[0024] As a further description of the above technical solution:

[0025] The right side of the cleaning plate is slidably connected to the left side of the filter plate, and the bottom of the cleaning plate is in contact with the top of the telescopic rod.

[0026] The above method involves the cleaning plate cleaning the filter plate under the action of upper and lower magnets, and the extension rod cushioning the cleaning plate as it moves downward.

[0027] As a further description of the above technical solution:

[0028] The external part of the extrusion cooling plate is slidably connected to the inner wall of the connecting pipe, and the left side of the connecting pipe is in contact with the right side of the conveying pipe.

[0029] The above scheme utilizes a compression cooling plate that receives power from the power block, allowing it to move. A connecting pipe connects to the transmission pipes on both sides, ensuring stable waste gas transmission.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, the cleaning plate moves upward under the action of the upper and lower magnetic magnets. Under the action of the shielding component, the cleaning plate moves downward under the action of gravity, causing the telescopic rod and spring to squeeze and buffer it, thereby achieving the treatment of non-condensable substances. In addition, it accelerates the heat transfer in the device, reduces the temperature of the exhaust gas more quickly, and promotes the efficient condensation of volatile organic compounds, improves the recovery efficiency, and increases the resource utilization rate.

[0032] 2. In this utility model, the extrusion cooling plate moves under the action of the electric block to compress the exhaust gas, causing it to heat up. Then, the extrusion cooling plate cools down under the action of the electric block, causing the water vapor in the exhaust gas to condense into water. Under the action of the collection component, the water inside the shell is collected, thereby cleaning the water vapor in the exhaust gas. In addition, it prevents water vapor condensation from causing equipment corrosion, ensuring the durability of the low-temperature condensation recovery device, thereby reducing equipment maintenance costs and failure risks.

[0040] 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.

[0041] Reference Figure 2 and Figure 3 This utility model provides an embodiment of a low-temperature condensation and recovery device for volatile organic compounds in ships, including a base plate 1, which is the foundation of the entire device and supports it. A cooling chamber 2 is fixedly connected to the top of the base plate 1. The cooling chamber 2 cools the exhaust gas, reducing its temperature. A filter chamber 3 is fixedly connected to the top of the cooling chamber 2. The filter chamber 3 performs preliminary filtration on the exhaust gas entering the device. Two filter plates 4 are fixedly connected to the inner wall of the filter chamber 3. The filter plates 4 filter out the solids remaining in the exhaust gas. A cleaning mechanism 5 is fixedly connected to the left side of each of the two filter plates 4. The cleaning mechanism 5 cleans the filter plates 4. A conveying pipe 7 is fixedly connected to the right side of the filter chamber 3. The conveying pipe conveys the filtered exhaust gas. A compression mechanism 8 is fixedly connected to the right side of the conveying pipe 7. The compression mechanism 8 compresses and cools the exhaust gas, causing it to separate out water. A temperature display 10 is fixedly connected to the top of the cooling chamber 2. The temperature display 10 displays the temperature of the cooling chamber 2 in real time.

[0042] Specifically, the exhaust gas enters the filter chamber 3 for preliminary filtration, is separated by the compression mechanism 8 under the action of the conveying pipe 7, and then enters the cooling chamber 2.

[0043] The cleaning mechanism 5 includes two fixed plates 51. The right sides of both fixed plates 51 are fixedly connected to the left sides of the two filter plates 4. The fixed plates 51 are fixed to the left sides of the filter plates 4. The bottom of both fixed plates 51 is fixedly connected to an upper magnetic magnet 52. The upper magnetic magnet 52 is fixed to the bottom of the fixed plates 51. Multiple guide plates 53 are fixedly connected to the inner wall of the filter chamber 3. A cleaning plate 54 is slidably connected to the adjacent side of every two guide plates 53. The top of the cleaning plate 54 is fixedly connected to a lower magnetic magnet 55. Multiple extension plates are fixedly connected to the bottom inner wall of the filter chamber 3. The telescopic rod 56 and multiple telescopic rods 56 are equipped with springs 57 on their exteriors. The guide plate 53 guides the cleaning plate 54, allowing it to move linearly. The cleaning plate 54 cleans the filter plate 4. The lower magnet 55 is magnetically attracted to the upper magnet 52, allowing the lower magnet 55 to move. The telescopic rods 56 and springs 57 are subjected to the force applied by the cleaning plate 54, thus squeezing it and providing a buffer force to the cleaning plate 54. The front and rear sides of the filter chamber 3 are fixedly connected with shielding components 6 for limiting the magnets.

[0044] Specifically, the upper and lower magnets 55 attract each other, thereby driving the cleaning plate 54 to move upward. The telescopic rod 56 and the spring 57 receive the force applied by the cleaning plate 54, thereby providing a buffer force for the cleaning plate 54. The guide plate 53 provides linear motion for the cleaning plate 54.

[0045] The shielding assembly 6 includes multiple electric push plates 61. The adjacent sides of the multiple electric push plates 61 are fixedly connected to the front and rear sides of the base plate 1. The electric push plates 61 receive the power of the equipment and are also the driving source of the shielding assembly 6. The driving end of the electric push plate 61 is fixedly connected to a force rod 62. The force rod 62 receives the power of the electric push plate 61 and moves accordingly. The rear side of the force rod 62 is fixedly connected to a blocking plate 63. The blocking plate 63 receives the pushing force of the force rod 62 and thus blocks the upper magnetic magnet 52. The blocking plate is insulated.

[0046] Specifically, the electric push plate 61 moves the force application rod 62, causing it to move the blocking plate 63. The blocking plate 63 then blocks the upper magnet 52, and due to its own insulation, it deprives the lower magnet 55 of its magnetic force, thus allowing the cleaning plate 54 to move downwards.

[0047] Reference Figure 1 , Figure 4 and Figure 5The compression mechanism 8 includes a housing 81. The left side of the housing 81 is fixedly connected to the right side of the conveying pipe 7. The housing 81 serves as an external component, connecting the internal compression components. Power blocks 82 are fixedly connected to both the front and rear sides of the housing 81. The power blocks 82 have two functions: providing a pushing force and a cooling effect to the extrusion cooling plate 84. Extrusion cooling plates 84 are fixedly connected to the adjacent sides of the two power blocks 82. A connecting pipe 83 is fixedly connected to the inner wall of the housing 81. The extrusion cooling plate 84 receives the pushing force and electric cooling from the power blocks 82 and has conductivity, thereby cooling the inside of its connecting pipe 83. The connecting pipe 83 connects the left and right conveying pipes 7. A collection component 9 for collecting cooling water after extrusion in the exhaust gas is fixedly connected to the bottom of the connecting pipe 83.

[0048] Specifically, the extrusion cooling plate 84, under the action of the electric block 82, extrudes and heats the exhaust gas entering the connecting pipe 83, and then cools the inside of the connecting pipe 83, thereby achieving the effect of converting the moisture in the exhaust gas into water.

[0049] The collection component 9 includes a collection tank 91, which serves as a connecting component, connecting the connecting pipe 83 and the recovery tank 92. The bottom of the collection tank 91 is fixedly connected to the recovery tank 92, which is the place where the collected water is stored. The inner wall of the recovery tank 92 is fixedly connected to two guide plates 93. A connecting plate 94 is slidably connected to the adjacent side of the two guide plates 93. The guide plates allow the connecting plate 94 to move linearly and make its movement stable. The connecting plate 94 is connected to other components.

[0050] Specifically, the collection tank 91 receives the water transferred from the connecting pipe 83, so that the water eventually enters the recycling tank 92, thereby stabilizing it, while the guide plate provides linear motion for the connecting plate 94.

[0051] Reference Figures 1 to 3Both connecting plates 94 have telescopic rods 95 fixedly connected to their bottoms. Each telescopic rod 95 has a spring 96 on its exterior. The telescopic rods 95 and springs 96 receive the force transmitted from the connecting plates 94, storing elastic force before transferring it back to the connecting plates 94. Each connecting plate 94 has a force-bearing plate 97 fixedly connected to its adjacent side. A telescopic plate 98 is fixedly connected to the bottom of the force-bearing plate 97. The connecting plates 94 move by receiving the force from the force-bearing plate 97. The force-bearing plate 97 receives water from the collection tank 91 and moves downwards under gravity. The telescopic plate 98 applies pressure under the force of the force-bearing plate 97 and also protects the springs 96. 6 and telescopic rod 2 95, to prevent them from being corroded by water. The right side of the cleaning plate 54 is slidably connected to the left side of the filter plate 4. The sliding plate moves up and down under the action of the lower magnet 55, thereby cleaning the filter plate 4. The bottom of the cleaning plate 54 is in contact with the top of the telescopic rod 1 56. When the cleaning plate 54 moves downward, the telescopic rod 1 56 provides a buffer for the cleaning plate 54. The outside of the compression cooling plate 84 is slidably connected to the inner wall of the connecting pipe 83. The left side of the connecting pipe 83 is in contact with the right side of the conveying pipe 7. The compression cooling plate 84 is moved by the action of the electric block 82. The connecting pipe 83 connects the conveying pipes 7 on both sides.

[0052] Specifically, the force plate 97 moves downward under the gravity of the water, which drives the connecting plate 94 to move. The telescopic rod 95 and the spring 96 provide buffer for the connecting plate 94. The telescopic plate 98 protects the telescopic rod 95 and the spring 96. The cleaning plate 54 cleans the filter plate 4 under the action of the lower magnet 55. The compression cooling plate 84 moves inside the connecting pipe 83 to compress the exhaust gas.

[0053] Working principle: Under the action of the upper magnetic magnet 52, the lower magnetic magnet 55 drives the cleaning plate 54 to move upward, thereby cleaning the filter plate 4. At this time, the operator opens the shielding assembly 6, which allows the electric push plate 61 to move the force rod 62 to drive the blocking plate 63, so that the blocking plate 63 blocks the upper magnetic magnet 52, preventing the lower magnetic magnet 55 from receiving the magnetic force of the upper magnetic magnet 52, and thus moves downward. At this time, the cleaning plate 54 cleans the filter plate 4. When the cleaning plate 54 moves downward, it also cleans the telescopic rod 5. Force is applied to spring 57 and telescopic rod 56, which in turn buffer the cleaning plate 54, thus cushioning its downward movement. At this time, electric push plate 61 causes the baffle plate to disengage from the upper magnet 52, allowing the lower magnet 55 to drive the cleaning plate 54 upward, thereby achieving the treatment of non-condensing substances. In addition, it accelerates heat transfer within the device, reduces the temperature of the exhaust gas more quickly, and promotes efficient condensation of volatile organic compounds, improving recovery efficiency and increasing resource utilization.

[0054] The filtered exhaust gas enters the outer casing 81 through the conveying pipe 7. The electric block 82 first moves the compression cooling plate 84, bringing the two compression cooling plates 84 closer together, thereby compressing the exhaust gas and raising its temperature. Then, the compression cooling plates 84 move away from each other, and under the action of the electric block 82, they continue to heat up, cooling the water vapor in the exhaust gas and generating water. Under the action of the collection component 9, the water enters the collection tank 91. The force plate 97 moves downward under the action of the water, causing the spring 96 and the telescopic rod 95 to compress, allowing the water on the force plate 97 to enter the recovery tank 92. This achieves the cleaning of water vapor in the exhaust gas, prevents water vapor condensation from causing equipment corrosion, ensures the durability of the low-temperature condensation recovery device, and reduces equipment maintenance costs and failure risks.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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. 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.
