Description

Technical Field

[0001] This utility model relates to the field of control cabinet technology, and in particular to an explosion-proof control cabinet for a gasification station. Background Technology

[0002] A control cabinet is a type of equipment in the field of electrical engineering. It mainly has functions such as centralized management of power distribution and signal processing, and is used to control various equipment and instruments.

[0003] The control cabinets at gasification stations are mainly used to manage and control the operation of various equipment within the station to ensure the safety and stability of gas production, storage, and transportation. In practice, control cabinets typically use fans or other gas supply devices to introduce external gas into the cabinet to reduce the temperature of electrical components and prevent overheating from affecting their performance and lifespan. However, during the conversion of liquefied natural gas into gaseous fuel, a large amount of mist often forms around the gasification station. This mist consists of tiny droplets. When the control cabinet ventilates to dissipate heat, external water mist may be brought into the cabinet, causing the internal electrical components to become damp or even damaged.

[0004] In summary, this application proposes an explosion-proof control cabinet for gasification stations to address the aforementioned technical issues. Utility Model Content

[0005] In order to overcome the disadvantage that when the control cabinet is ventilated and cooled, external water mist may be brought into the cabinet, which may cause the internal electrical components to become damp or even damaged, this utility model provides an explosion-proof control cabinet for gasification stations.

[0006] The technical solution of this utility model is as follows: an explosion-proof control cabinet for a gasification station, comprising a cabinet body; further comprising an air inlet pipe, a fan, a ventilation duct, an air outlet pipe, a gas supply pipe, a sealing cover, and a sleeve; the air inlet pipe is fixedly connected to the cabinet body; two fans are installed in the air inlet pipe; the ventilation duct is fixedly connected to the cabinet body, and the ventilation duct is fixedly connected to the air inlet pipe; an air outlet pipe is fixedly connected to the outer wall of the right side of the cabinet body, and the air outlet pipe is fixedly connected to the ventilation duct; the ventilation duct has an air channel, and the air inlet pipe is connected to the air channel, and the air channel is connected to the air outlet pipe; the air outlet pipe is connected to a gas supply pipe, and the gas supply pipe passes through the cabinet body; the ventilation duct has several placement slots, and the placement slots are connected to the air channel; each placement slot contains a sleeve for storing desiccant, and the sleeve is configured with a mesh structure; each sleeve is fixedly connected to a sealing cover.

[0007] Furthermore, it also includes movable plugs and limiting blocks; each placement slot has a movable plug slidably connected to it; a magnet is provided on the front side of the movable plug and a magnet is provided on the rear side of the sleeve, and the two are positioned correspondingly; each movable plug is fixedly connected to two limiting blocks, and the limiting blocks are slidably connected to the air duct.

[0008] Furthermore, it also includes a mounting plate, an air supply pipe, an air blowing pipe 1, and an air blowing pipe 2; the inner wall of the cabinet is fixedly connected to a mounting plate for installing and fixing electrical components; the inner wall of the cabinet is fixedly connected to an air supply pipe, the air supply pipe is fixedly connected to the mounting plate, and the air supply pipe is connected to an air transmission pipe; the air supply pipe is connected to several air blowing pipes 1, and air blowing pipes 1 are fixedly connected to the mounting plate; the air supply pipe is connected to several air blowing pipes 2.

[0009] Furthermore, it also includes dust filters; two dust filters are fixed to the air intake duct, and the dust filters are located to the left of the fan.

[0010] Furthermore, the dustproof net and the air inlet duct are designed to be detachably connected.

[0011] Furthermore, it also includes a humidity indicator; each sealing cap is equipped with a humidity indicator.

[0012] The beneficial effects are:

[0013] The gas enters the mesh-structured sleeve and comes into contact with the desiccant inside, absorbing and removing moisture from the gas. The dried gas then flows into the cabinet through the exhaust duct and gas supply pipe for heat dissipation. This prevents external water vapor from being easily brought into the cabinet when the control cabinet is ventilating for heat dissipation, which could cause internal electrical components to become damp or even be damaged.

[0014] The desiccant can be removed by manually pulling the sealing cover and pulling the sleeve out of the placement slot. Multiple sleeves are provided, and while one sleeve is being removed, the desiccant inside the other sleeves can continue to dry the desiccant, ensuring the overall drying effect. This allows the desiccant to be removed without interrupting the ventilation operation, ensuring the normal operation and performance stability of the entire control cabinet.

Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] It also includes a movable plug 9 and a limiting block 10; each placement slot 42 has a movable plug 9 slidably connected to it; a magnet is provided on the front side of the movable plug 9 and a magnet is provided on the rear side of the sleeve 8, and the two are in corresponding positions; each movable plug 9 is fixedly connected to two limiting blocks 10, and the limiting blocks 10 are slidably connected to the air duct 41.

[0027] It also includes a mounting plate 111, an air supply pipe 112, an air blowing pipe 113, and an air blowing pipe 114; the mounting plate 111 is fixedly connected to the inner wall of the cabinet 1; the air supply pipe 112 is fixedly connected to the inner wall of the cabinet 1, the air supply pipe 112 is fixedly connected to the mounting plate 111, and the air supply pipe 112 is connected to the air supply pipe 6; the air supply pipe 112 is connected to several air blowing pipes 113, and the air blowing pipes 113 are fixedly connected to the mounting plate 111; the air supply pipe 112 is connected to several air blowing pipes 114.

[0028] It also includes a dustproof net 101; the air inlet duct 2 is fixedly connected to two dustproof nets 101, and the dustproof nets 101 are located to the left of the fan 3.

[0029] The dustproof net 101 and the air inlet duct 2 are designed to be detachably connected. When the surface of the dustproof net 101 is covered with a lot of dust, it can be manually removed and replaced.

[0030] It also includes a humidity indicator 102; each sealing cover 7 is equipped with a humidity indicator 102, which can monitor the humidity of the desiccant inside the sleeve 8, so as to facilitate manual understanding of the desiccant usage and subsequent replacement.

[0031] The control cabinet's heat dissipation mechanism works as follows: Fan 3 is manually operated to draw outside air into the intake duct 2. The air inside the intake duct 2 then flows sequentially through the ventilation duct 41, the exhaust duct 5, and the gas supply pipe 6 into the cabinet 1, thereby dissipating heat from the electrical components inside the cabinet 1 and preventing overheating that could affect their performance and lifespan. However, during the process of converting liquefied natural gas into gaseous fuel at the gasification station, a large amount of mist is often generated. This mist consists of tiny droplets. When the control cabinet is ventilated for heat dissipation, external water mist can easily be drawn into the cabinet 1, causing the internal electrical components to become damp or even damaged. Therefore, during operation, a sleeve 8 containing desiccant and a sealing cap 7 are manually inserted into the placement slot 42. The sleeve 8 is designed with a mesh structure. When the air is drawn into the intake duct 2... When the gas passes through the air duct 41 of the ventilation duct 4, it enters the inside of the mesh structure sleeve 8 and comes into contact with the desiccant inside. The desiccant inside the sleeve 8 dries the gas and absorbs and removes the moisture in the gas. The dried gas then passes through the air outlet duct 5 and the air supply pipe 6 into the cabinet 1 for heat dissipation. This prevents external water vapor from being easily brought into the cabinet 1 when the control cabinet is ventilating for heat dissipation, which could cause the internal electrical components to become damp or even damaged. It should be noted that a dust filter 101 is installed on the left side of the fan 3. The dust filter 101 can filter dust in the gas and prevent external dust from being drawn into the cabinet. The dust filter 101 is detachably connected to the air inlet duct 2. When a lot of dust adheres to the surface of the dust filter 101, it can be manually removed and replaced.

[0032] Meanwhile, considering that the desiccant will absorb a large amount of moisture after a period of use, and its drying effect will gradually weaken, it needs to be replaced regularly. However, the current replacement method usually requires stopping the ventilation of the control cabinet in order to remove and replace the desiccant. But this method will interrupt the heat dissipation process of the control cabinet, thereby affecting its normal operation and performance stability, which is not conducive to the continuous and efficient operation of the control cabinet. Therefore, when the desiccant inside the sleeve 8 absorbs a large amount of moisture and the drying effect decreases, the sealing cover 7 is manually pulled to pull the sleeve 8 out of the placement slot 42 to remove the desiccant. Multiple sleeves 8 are provided, and during the removal of one sleeve 8, the desiccant inside other sleeves 8 can be removed. Drying is performed to ensure the overall drying effect, allowing the desiccant to be removed without interrupting ventilation, thus ensuring the normal operation and performance stability of the overall control cabinet. Simultaneously, to prevent gas in the air duct 41 from flowing out through the placement slot 42 and failing to enter the outlet duct 5 and air supply pipe 6 for subsequent heat dissipation, a movable plug 9 and a limiting block 10 are provided. A magnet is located on the front of the movable plug 9 and a magnet is located on the rear of the sleeve 8. The movable plug 9 and the sleeve 8 are magnetically attracted to each other. When the sleeve 8 is manually pulled out of the placement slot 42, the sleeve 8 simultaneously moves the movable plug 9. When the limiting block 10 moves to the front of the air duct 41, it cannot move further. The sleeve 8 can then be manually pulled out of the placement slot 42. Figure 4 As shown, under the restriction of the limiting block 10, the movable plug 9 separates from the sleeve 8 and seals the placement groove 42, so that when the sleeve 8 is pulled out to replace the desiccant, the gas in the air duct 41 cannot flow out to the outside through the placement groove 42, thus ensuring the overall heat dissipation function. After the desiccant inside the sleeve 8 is replaced, it is inserted back into the placement groove 42, and the movable plug 9 and the limiting block 10 are pushed back into the rear side of the placement groove 42. In addition, a humidity indicator 102 is provided on the sealing cover 7, which can monitor the humidity of the desiccant inside the sleeve 8, so as to facilitate manual understanding of the desiccant usage and facilitate subsequent replacement.

[0033] Meanwhile, considering that when external gas is introduced into the cabinet 1, it is difficult for the gas to fully contact the internal electrical components, the dried gas is introduced into the gas supply pipe 6 and then into the gas supply pipe 112. The electrical components inside the cabinet 1 are mounted on the mounting plate 111. The gas in the gas supply pipe 112 can directly blow air onto the surface of the electrical components to dissipate heat through the first air blowing pipe 113 and the second air blowing pipe 114, thereby enhancing the overall heat dissipation effect.

[0034] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
