Description

Technical Field

[0001] This utility model relates to the field of carbon dioxide production technology, specifically to a methanol removal device in a carbon dioxide production process. Background Technology

[0002] Methanol is a colorless and odorless gas or a colorless and odorless gas with a slightly acidic smell. It is also a common greenhouse gas and a component of air. In the production of carbon dioxide, a certain amount of methanol gas is produced, so it is necessary to remove methanol from carbon dioxide through a removal device.

[0003] For example, a methanol removal device in a carbon dioxide production process, authorized by announcement number CN220779613U, includes a housing. An air pump is installed on one side of the housing, and the exhaust end of the air pump is inserted into the inside of the housing. An air inlet pipe is fixedly connected to the side of the housing away from the air pump. Although the above document can remove methanol from carbon dioxide during carbon dioxide recycling and reuse, the operation of the device can be improved without stopping the operation when the activated carbon adsorption plate is replaced through the cooperation between the positioning plate and the blocking component, thereby effectively improving the methanol removal efficiency.

[0004] However, in existing removal devices, when removing methanol from carbon dioxide, carbon dioxide enters the housing through the inlet pipe and is adsorbed by the activated carbon filter. Because the flow rate of carbon dioxide inside the housing is relatively fast, methanol cannot fully contact the activated carbon filter, resulting in incomplete methanol removal and thus reducing the effectiveness of the removal device in removing methanol from inside the carbon dioxide. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a methanol removal device in a carbon dioxide production process. This device solves the problem that the rapid flow rate of carbon dioxide inside the shell prevents methanol from fully contacting the activated carbon filter, resulting in incomplete methanol removal and reduced effectiveness of the removal device in removing methanol from inside the carbon dioxide.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a methanol removal device in a carbon dioxide production process, comprising a housing, a cover fixedly connected to the top of the housing, an inlet pipe and an outlet pipe respectively connected to both sides of the housing, a filter screen and a guide pipe disposed inside the housing, and a connecting structure disposed between the guide pipe and the inlet pipe; the connecting mechanism comprises a connecting seat, a handle, a slide groove, a slider, a locking block and a spring; the connecting seat is sleeved on the outer wall of the inlet pipe, a handle is fixedly connected to the outer wall of the connecting seat, a slide groove is formed on the outer wall of the inlet pipe, a slider is fixedly connected to the inner wall of the connecting seat, the outer wall of the slider slidably engages with the inner wall of the slide groove, a spring is fixedly connected to the inner wall of the connecting seat, a locking block is fixedly connected to the end of the spring, and the outer wall of the locking block is inserted into the inner wall of the guide pipe.

[0007] Preferably, a vertical rod is fixedly connected to the side of the locking block near the spring, and the outer wall of the vertical rod is sleeved on the inner wall of the spring.

[0008] Preferably, a sealing ring is fixed to the outer wall of the end of the air intake pipe, and the outer wall of the sealing ring is attached to the inner wall of the air guide pipe.

[0014] Beneficial effects

[0015] This invention provides a methanol removal device for a carbon dioxide production process. It offers the following advantages: This methanol removal device, through the cooperation of a connecting seat, handle, slide groove, slider, locking block, spring, first guide plate, and second guide plate, reduces the flow velocity of carbon dioxide, thereby effectively removing methanol. This solves the problem that the high flow velocity of carbon dioxide inside the casing prevents methanol from fully contacting the activated carbon filter, resulting in incomplete methanol removal and reduced effectiveness in removing methanol from the carbon dioxide inside the device.

[0016] By coordinating the vertical plate, through holes, and positioning blocks, concentrated carbon dioxide gas is dispersed into multiple small airflows through the through holes, thereby covering the entire surface of the filter screen. This solves the problem that when carbon dioxide gas enters the interior of the shell through the air inlet pipe, it easily forms a converging effect with high flow velocity in the center or low flow velocity at the edge, causing the activated carbon in the central area of ​​the filter screen to quickly become saturated while the activated carbon in the edge area is not fully utilized, resulting in uneven contact between carbon dioxide gas and the filter screen surface.

[0023] 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.

[0024] Because the carbon dioxide flows relatively fast inside the shell, methanol cannot fully contact the activated carbon filter, resulting in incomplete methanol removal and reducing the effectiveness of the removal device in removing methanol from inside the carbon dioxide.

[0025] In view of this, the present invention provides a methanol removal device in a carbon dioxide production process. Through the cooperation of the connecting seat, handle, slide groove, slider, locking block, spring, first guide plate and second guide plate, the flow velocity of carbon dioxide is reduced, thereby fully removing methanol. This solves the problem that the methanol cannot fully contact the activated carbon filter due to the relatively fast flow velocity of carbon dioxide inside the shell, resulting in incomplete methanol removal and reducing the effectiveness of the removal device in removing methanol from inside the carbon dioxide.

[0026] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly introduced below.

[0027] Example 1, by Figure 1-5 It is understood that the methanol removal device in the carbon dioxide production process of this case includes a shell 1, a shell cover 2 fixedly connected to the top of the shell 1, an air inlet pipe 4 and an exhaust pipe 5 respectively connected to the two sides of the shell 1, a filter screen 7 and an air guide pipe 9 are provided inside the shell 1, and a connecting structure is provided between the air guide pipe 9 and the air inlet pipe 4; the connecting mechanism includes a connecting seat 10, a handle 11, a slide groove 12, a slider 13, a locking block 14 and a spring 15; the connecting seat 10 is sleeved on the outer wall of the air inlet pipe 4, the handle 11 is fixedly connected to the outer wall of the connecting seat 10, the slide groove 12 is opened on the outer wall of the air inlet pipe 4, the slider 13 is fixedly connected to the inner wall of the connecting seat 10, the outer wall of the slider 13 slides and locks into the inner wall of the slide groove 12, the spring 15 is fixedly connected to the inner wall of the connecting seat 10, the locking block 14 is fixedly connected to the end of the spring 15, and the outer wall of the locking block 14 is inserted into the inner wall of the air guide pipe 9;

[0028] In the specific implementation process, it is worth noting that the shell 1 and the cover 2 can be connected by bolts, allowing the cover 2 to be disassembled. A sealing gasket is placed between them, and the gasket model only needs to meet the working conditions to improve the sealing effect. When removing methanol from the carbon dioxide, the operator first removes the cover 2, then inserts the gas guide tube 9 into the end of the air inlet tube 4. After that, the operator moves the connecting seat 10, which drives the slider 13 to slide in the slide groove 12, limiting the axial movement of the connecting seat 10. The connecting seat 10 then drives the locking block 14 to move. When the locking block 14 moves to the side wall of the gas guide tube 9, the locking block 14 is squeezed by the gas guide tube 9, causing the spring 15 to compress. The model of the spring 15 is selected according to the actual situation, as long as it meets the working conditions. The locking block 14 moves into the interior of the connecting seat 10. When the locking block 14 moves to the corresponding slot position of the gas guide tube 9, Spring 15 rebounds, and the elastic force causes the locking block 14 to insert into the slot on the outer wall of the air guide pipe 9, thereby fixing the air guide pipe 9 to the air inlet pipe 4. After completion, the operator re-fixes the cover 2 to the top of the housing 1. The operator opens the valves on the air inlet pipe 4 and the exhaust pipe 5, and the external carbon dioxide enters the air guide pipe 9 through the air inlet pipe 4. At this time, according to fluid mechanics, the smaller the cross-sectional area of ​​the channel, the faster the airflow speed. Conversely, increasing the inlet cross-sectional area can reduce the flow velocity. For example, the diameter of the air inlet pipe 4 is smaller than the diameter of the air guide pipe 9. At this time, the airflow speed decreases due to the expansion of space. The flow velocity of carbon dioxide in the housing 1 decreases. The carbon dioxide slowly flows through multiple filter screens 7 in sequence. The filter screens 7 are activated carbon filter screens. At this time, the filter screens 7 adsorb the methanol inside the carbon dioxide. The carbon dioxide with removed methanol is finally discharged into the housing 1 through the exhaust pipe 5, thereby reducing the flow velocity of carbon dioxide and thus fully removing methanol.

[0029] Furthermore, a vertical rod 16 is fixedly connected to the side of the locking block 14 near the spring 15, and the outer wall of the vertical rod 16 is sleeved on the inner wall of the spring 15.

[0030] In the specific implementation process, it is worth noting that when the spring 15 moves, the locking block 14 drives the spring 15 and the vertical rod 16 to move, so that the spring 15 moves on the vertical rod 16, thereby limiting the spring 15.

[0031] Furthermore, a sealing ring 17 is fixed to the outer wall of the end of the air intake pipe 4, and the outer wall of the sealing ring 17 is attached to the inner wall of the air guide pipe 9.

[0032] In the specific implementation process, it is worth noting that the material of the sealing ring 17 can be selected according to the actual situation, as long as it meets the working conditions. The sealing ring 17 increases the sealing effect between the air guide pipe 9 and the air inlet pipe 4.

[0033] Furthermore, a first guide plate 21 is fixedly connected to the bottom of the inner wall of the housing 1 near the air duct 9, and a second guide plate 22 is fixedly connected to the top of the inner wall of the housing cover 2 near the air inlet pipe 4.

[0034] In the specific implementation process, it is worth noting that both the first guide plate 21 and the second guide plate 22 adopt arc-shaped curved surfaces and are arranged in an alternating manner with an included angle of 60°. The surfaces of the first guide plate 21 and the second guide plate 22 are coated with polytetrafluoroethylene to reduce gas flow resistance. After functional verification, CFD simulation shows that after adding the first guide plate 21 and the second guide plate 22, the residence time of carbon dioxide gas in the housing 1 is extended from 1.2 seconds to 2.8 seconds, and the probability of methanol molecules contacting the filter screen 7 is increased by 45%, thereby further improving the methanol removal effect.

[0035] Furthermore, a socket 23 is fixedly connected to the bottom of the inner wall of the housing 1 and the top of the inner wall of the housing cover 2 on the other side near the exhaust pipe 5, and the inner wall of the socket 23 is inserted into the outer wall of the filter screen 7.

[0036] In the specific implementation process, it is worth noting that rubber pads are provided between the top and bottom of the filter screen 7 and the socket 23, and rubber pads are also provided between the front and rear positions of the filter screen 7 and the inner wall of the housing 1. The material of the rubber pads is selected according to the actual situation, as long as it meets the working conditions, to improve the sealing between the housing 1, the socket 23 and the filter screen 7. When replacing the filter screen 7, the operator removes the housing cover 2. At this time, the socket 23 on the housing cover 2 is removed from the top of the filter screen 7. After that, the operator removes the filter screen 7 from the socket 23 inside the housing 1 and replaces the filter screen 7. The bottom of the replacement filter screen 7 is inserted into the socket 23 in the housing 1. After that, the socket 23 on the housing cover 2 is inserted into the top of the replacement filter screen 7 to fix the filter screen 7, thus realizing the replacement of the filter screen 7.

[0037] Example 2, by Figure 1 , 2 As can be seen from 5, the side wall of the filter screen 7 is provided with an auxiliary mechanism; the auxiliary mechanism includes a vertical plate 18, a through hole 19 and a positioning block 20; the vertical plate 18 is fixedly connected to the side wall of the filter screen 7 by bolts, and the positioning block 20 is fixedly connected to the side wall of the vertical plate 18, and the outer wall of the positioning block 20 is inserted into the outer wall of the filter screen 7.

[0038] In the specific implementation process, it is worth noting that the upright plate 18 is made of stainless steel. Before the staff fixes the filter screen 7 to the inside of the housing 1, the staff moves the upright plate 18, which drives the positioning block 20 to move. The positioning block 20 is inserted into the positioning hole on the outer wall of the filter screen 7 to position the upright plate 18. After that, the staff turns the bolt to fix the upright plate 18 to the filter screen 7. Finally, the filter screen 7 with the upright plate 18 is fixed to the housing 1. When removing methanol inside the carbon dioxide, the carbon dioxide gas comes into contact with the surface of the upright plate 18. Then, the carbon dioxide gas comes into contact with the filter screen 7 through several through holes 19 on the surface of the upright plate 18, so as to disperse the concentrated carbon dioxide gas into multiple small airflows through the through holes 19, thereby covering the entire surface of the filter screen 7.

[0039] Furthermore, a wind speed sensor 8 is bolted to the inner wall of the housing 1 on the side near the exhaust pipe 5.

[0040] In the specific implementation process, it is worth noting that the model of wind speed sensor 8 is TSI9565-A10. The connection method between wind speed sensor 8 and external controller is analog signal connection. Connect the positive terminal of the sensor to the + terminal of the controller AI module and the negative terminal to the - terminal. A 250Ω precision resistor needs to be connected in series. 0~10V voltage signal. The output terminal of the sensor is connected to the voltage input port of the controller AI module. Note that it is connected to a common ground. The operator can disassemble and assemble the wind speed sensor 8 by turning the bolt. When the speed of the gas flow detected by the wind speed sensor 8 decreases to a predetermined value, the wind speed sensor 8 transmits the signal to the controller. The controller issues an alarm, thereby reminding the operator to replace the filter screen 7, realizing the monitoring of the degree of blockage of the filter screen 7.

[0041] Furthermore, a handle 3 is fixedly connected to the top of the cover 2, and a connecting lug 6 is fixedly connected to the outer wall of the housing 1;

[0042] In the specific implementation process, it is worth noting that when the staff replaces the filter screen 7, the staff first holds the handle 3 and moves the handle 3, which moves the cover 2 away from the housing 1, exposing the filter screen 7 for replacement. After the replacement is completed, the staff uses the handle 3 to put the cover 2 back on the housing 1 and fix it in place. The staff can easily move the cover 2 using the handle 3. The surface of the connecting ear 6 has a mounting hole, through which the staff installs the removal device into the working position.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
