Description

Technical Field

[0001] This invention relates to the field of methanol synthesis reactor technology, specifically to a method of using a radial methanol synthesis reactor. Background Technology

[0002] A radial methanol synthesis reactor is a methanol synthesis device in which the gas flow is perpendicular to the axis of the equipment. Its core design optimizes gas distribution and pressure drop through an annular catalyst bed. The boiling water tube in the radial methanol synthesis reactor is an important component. Methanol synthesis is a strongly exothermic reaction. Water in the boiling water tube absorbs the heat of reaction and vaporizes to maintain the bed temperature. Currently, the boiling water tube inside the radial methanol synthesis reactor is prone to leakage due to corrosion and frictional vibration of the catalyst particles. Once the boiling water tube loses pressure, methanol synthesis gas can easily enter the gas tank, causing safety hazards. It is not convenient to realize automatic control to prevent leakage and maintain pressure, as well as to vent the boiling water tube. At the same time, it is not convenient to reduce the axial movement of gas pressure. When the outer distribution cylinder is blocked, it can easily increase the radial movement range of the gas flow, affecting the smoothness of exhaust. It is not convenient to replace catalyst particles in sections without stopping the machine. It is also not convenient to assist in the comprehensive testing of catalyst permeability and uniformity, which can easily affect the operator's judgment of the inlet pressure.

[0003] Therefore, we propose a radial methanol synthesis reactor. Summary of the Invention

[0004] The purpose of this invention is to provide a method for using a radial methanol synthesis reactor, in order to solve the problems mentioned in the background art that current radial methanol synthesis reactors are not convenient for automatic control of leakage prevention and pressure maintenance, boiling water pipe venting, and are not convenient for assisting in comprehensive testing of catalyst flow uniformity.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a radial methanol synthesis reactor, comprising a reaction mounting component, wherein a boiling water control component is mounted on the reaction mounting component; the boiling water control component is used for the flow of boiling water; an evacuation control component is mounted on the boiling water control component; a radial reaction element is mounted on the reaction mounting component; a sealing and blocking component is mounted on the radial reaction element; the sealing and blocking component is used to ensure smooth gas flow; a uniformity test component is mounted on the reaction mounting component; the uniformity test component is used to detect the pressure drop balance of the radial reaction element; the reaction mounting component includes: a reaction tower body and an inlet pipe, wherein the inlet pipe is fixedly mounted at the bottom of the reaction tower body; the inlet pipe is a tee pipe, and a flange cover is bolted to the bottom of the inlet pipe;

[0006] The boiling water control components include: a boiling water rectifier ring, a boiling water pipe, a boiling water discharge pipe, a boiling water inlet pipe, an vent pipe, and a pressure supply pipe. Two boiling water rectifier rings are provided, located on opposite sides of the radial reaction vessel. A ring of boiling water pipe is fixedly installed between the two boiling water rectifier rings, and this ring connects to the boiling water rectifier ring. The boiling water discharge pipe is fixedly installed on the upper boiling water rectifier ring and passes through the main body of the reaction tower. The boiling water discharge pipe has an L-shaped structure and is equipped with... The system includes: a solenoid valve; a boiling water discharge pipe for connecting to the steam drum return pipe; a boiling water inlet pipe fixedly installed on the lower boiling water rectifier ring, for connecting to the steam drum; a solenoid valve on the boiling water inlet pipe; a drain pipe fixedly installed on the boiling water inlet pipe, also equipped with a solenoid valve; a water collection tank outside the drain pipe; a pressure supply pipe fixedly installed on the upper boiling water rectifier ring; the pressure supply pipe passing through the main body of the reaction tower; a solenoid valve on the pressure supply pipe; and an air pump connected to the pressure supply pipe.

[0007] The venting control component includes: a pressure measuring tube, a piston, a pressure spring, and a venting switch. The pressure measuring tube is fixedly installed on the upper boiling water rectifier ring. The piston is slidably sleeved inside the pressure measuring tube. The pressure measuring tube passes through the main body of the reaction tower. A pressure spring is sleeved inside the pressure measuring tube, and the pressure spring is connected between the pressure measuring tube and the piston. The venting switch is fixedly installed inside the pressure measuring tube. The tail of the piston is used to squeeze the venting switch.

[0008] The vent switch is electrically connected to the solenoid valves on the boiling water discharge pipe, boiling water inlet pipe, vent pipe, and pressure supply pipe, as well as the air pump connected to the external pressure supply pipe.

[0009] When a leak occurs in the boiling water pipe, the pressure inside the pipe drops. The pressure is insufficient to push the piston to compress the pressure spring. At this time, the piston, under the pressure of the pressure spring, will no longer press the vent switch. The vent switch can then control the solenoid valve on the boiling water discharge pipe to close to prevent backflow, the solenoid valve on the boiling water inlet to close to prevent backflow, and the solenoid valve on the vent pipe to open, independently discharging the boiling water in the boiling water pipe. At the same time, it controls the solenoid valve on the pressure supply pipe to open to supply pressure, and simultaneously controls the external air pump connected to the pressure supply pipe to be energized to maintain air supply. However, the air supply pressure is insufficient to compress the pressure spring, ensuring that there is always pressure available in the boiling water pipe to prevent methanol synthesis gas from seeping into the boiling water pipe. This also achieves the independent discharge of the boiling water in the boiling water pipe to prevent continuous leakage.

[0010] Preferably, the reaction mounting further includes: a pressure gauge and an exhaust pipe, wherein the pressure gauge is fixedly mounted on the bottom side of the air inlet pipe; the exhaust pipe is fixedly mounted on the top of the reaction tower body; and the bottom of the reaction tower body is provided with four support legs.

[0011] Preferably, the radial reaction component includes: an outer distribution cylinder, a bottom plate, and a support plate.

The bottom plate is fixedly sleeved inside the main body of the reaction tower. The support plate is fixedly installed at the top of the outer distribution cylinder, and the support plate has a ring of slots. The support plate is sleeved inside the main body of the reaction tower.

[0012] Preferably, the radial reaction component further includes: a central distribution pipe and partition plates, wherein the central distribution pipe is fixedly installed inside the main body of the reaction tower; the central distribution pipe is fixedly sleeved inside the bottom plate; the top of the central distribution pipe is fixedly installed at the bottom of the support plate; ventilation holes are provided on the central distribution pipe and the outer distribution cylinder respectively; a row of partition plates is fixedly installed inside the outer distribution cylinder, and the row of partition plates is respectively sleeved on the outside of the central distribution pipe; the row of partition plates, the bottom plate and the support plate are equidistantly distributed.

[0013] Preferably, the radial reaction element further includes: flange pipes, a row of flange pipes fixedly installed on the outer distribution cylinder, and the row of flange pipes passing through the main body of the reaction tower; the row of flange pipes are paired up, and each pair of flange pipes is used for adding and discharging reaction particles; flange covers are bolted to the ends of the row of flange pipes; a ring of boiling water pipes is fixedly installed on the partition plate, the bottom plate and the support plate; catalyst particles are filled between the row of partition plate, the bottom plate and the support plate.

[0014] Preferably, the sealing and blocking component includes: a blocking ring, a sealing cylinder, and an electromagnet. A row of blocking rings is fixedly sleeved inside the main body of the reaction tower. Each row of blocking rings is fixedly sleeved on the outer distribution cylinder, and each row of blocking rings has a through hole. A sealing cylinder is attached between each row of blocking rings, the bottom plate, and the support plate, and the sealing cylinder is rotatably sleeved on the outer distribution cylinder. The sealing cylinder has a vent hole aligned with the outer distribution cylinder. Two electromagnets are fixedly installed on each row of sealing cylinders. The two electromagnets are used to adjust the misalignment between the vent holes on the sealing cylinder and the vent holes on the outer distribution cylinder. A row of electromagnets on the right side magnetically attracts a row of flange pipes. Each row of sealing cylinders has two through grooves for sliding on a row of flange pipes to prevent jamming.

[0015] Preferably, the uniform test piece includes: a drive motor and a drive screw, wherein the drive motor is fixedly mounted on the flange cover at the bottom of the intake pipe; the output shaft of the drive motor passes through the flange cover at the bottom of the intake pipe; a drive screw is fixedly mounted on the output shaft of the drive motor; and the diameter of the drive screw is smaller than the inner diameter of the intake pipe.

[0016] Preferably, the uniformity test piece further includes: a lifting baffle, the lifting baffle being threadedly connected to the drive screw, and the lifting baffle having a through hole; the lifting baffle being slidably sleeved on the central distribution tube; the length of the lifting baffle being greater than the spacing between adjacent partition plates; a groove being provided on the outer side of the lifting baffle; a protruding strip being provided on the inner side of the central distribution tube, and the groove on the outer side of the lifting baffle sliding on the protruding strip on the inner side of the central distribution tube.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention employs a venting control component in conjunction with a boiling water control component to automatically prevent methanol synthesis gas from seeping into the boiling water pipe under pressure due to boiling water pipe rupture and flowing into the gas chamber. It can achieve automatic pressure protection and reduce the risk of methanol backflow. At the same time, this structure can automatically control the venting of residual boiling water inside the boiling water pipe, which can effectively reduce the pollution of catalyst particles caused by boiling water pipe leakage and reduce economic losses.

[0019] By using a radial reactor, partitioned radial exhaust gas synthesis can be achieved. This ensures pressure drop resistance while allowing for more uniform use of catalyst particles, reducing the axial movement range of methanol synthesis gas within the catalyst particles, and promoting its radial movement.

[0020] The use of a lifting baffle and partition plate for separation allows staff to quickly check the consistency of catalyst particle pressure drop flow in the central distribution pipe and the external distribution cylinder. This avoids the problem of difficulty in judging the flow of catalyst particles in different locations and the blockage of the central distribution pipe or the external distribution cylinder by directly observing the pressure gauge, which is traditional. It also facilitates the replacement of catalyst particles without stopping the machine, ensuring continuous production. In addition, the partitioned structure eliminates the need to replace the entire catalyst particles, making the structure more compact and economical. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figures 1 to 10 As shown:

[0034] This invention provides a technical solution: a radial methanol synthesis reactor, comprising a reaction mounting component 1, on which a boiling water control component 2 is mounted; the boiling water control component 2 is used for the flow of boiling water; an evacuation control component 3 is mounted on the boiling water control component 2; a radial reaction component 4 is mounted on the reaction mounting component 1; a sealing and blocking component 5 is mounted on the radial reaction component 4; the sealing and blocking component 5 is used to ensure smooth gas flow; a uniformity test component 6 is mounted on the reaction mounting component 1; the uniformity test component 6 is used to detect the pressure drop balance of the radial reaction component 4; the reaction mounting component 1 includes: a reaction tower body 101 and an inlet pipe 102, the inlet pipe 102 is fixedly mounted at the bottom of the reaction tower body 101; the inlet pipe 102 is a three-way pipe, and a flange cover is bolted to the bottom of the inlet pipe 102; four support legs are provided at the bottom of the reaction tower body 101.

[0035] The reaction installation component 1 further includes: a pressure gauge 103 and an exhaust pipe 104. The pressure gauge 103 is fixedly installed on the bottom side of the inlet pipe 102; the exhaust pipe 104 is fixedly installed on the top of the reaction tower body 101; the inlet pipe 102 is connected to the outlet of the methanol synthesis gas mixing equipment; the boiling water control component 2 includes: a boiling water rectifier ring 201, a boiling water pipe 202, a boiling water discharge pipe 203, a boiling water inlet pipe 204, an vent pipe 205, and a pressure supply pipe 206. Two boiling water rectifier rings 201 are provided, and the two boiling water rectifier rings 201 are respectively located in the radial direction. On both sides of component 4; a ring of boiling water pipe 202 is fixedly installed between the two boiling water rectifier rings 201, and the ring of boiling water pipe 202 is connected to the boiling water rectifier ring 201; a boiling water discharge pipe 203 is fixedly installed on the upper boiling water rectifier ring 201, and the boiling water discharge pipe 203 passes through the main body 101 of the reaction tower; the boiling water discharge pipe 203 has an L-shaped structure; a solenoid valve is provided on the boiling water discharge pipe 203; the boiling water discharge pipe 203 is used to connect to the steam drum return pipe; a boiling water inlet pipe 204 is fixedly installed on the lower boiling water rectifier ring 201, and the boiling water inlet pipe 204 is used to connect to The boiler is connected to a steam drum; a solenoid valve is installed on the boiling water inlet pipe 204; a drain pipe 205 is fixedly installed on the boiling water inlet pipe 204, and a solenoid valve is installed on the drain pipe 205; a water collection tank is externally connected to the drain pipe 205; a pressure supply pipe 206 is fixedly installed on the upper boiling water rectifier ring 201; the pressure supply pipe 206 passes through the main body 101 of the reaction tower; a solenoid valve is installed on the pressure supply pipe 206; control switches are externally connected to the solenoid valves on the boiling water outlet pipe 203, boiling water inlet pipe 204, drain pipe 205, and pressure supply pipe 206; an air pump is externally connected to the pressure supply pipe 206; the drain pipe 206 is connected to the air supply pipe 206. The control component 3 includes: a pressure measuring tube 301, a piston 302, a pressure spring 303, and a drain switch 304. The pressure measuring tube 301 is fixedly installed on the upper boiling water rectifier ring 201; the piston 302 is slidably sleeved inside the pressure measuring tube 301; the pressure measuring tube 301 passes through the reaction tower body 101; the pressure spring 303 is sleeved inside the pressure measuring tube 301 and is connected between the pressure measuring tube 301 and the piston 302; the drain switch 304 is fixedly installed inside the pressure measuring tube 301; the tail of the piston 302 is used to squeeze the drain switch 304.The vent switch 304 is electrically connected to the solenoid valves on the boiling water discharge pipe 203, boiling water inlet pipe 204, vent pipe 205, and pressure supply pipe 206, as well as the air pump connected to the pressure supply pipe 206. By using the vent control component 3 in conjunction with the boiling water control component 2, automatic control can be achieved to prevent methanol synthesis gas from seeping into the boiling water pipe 202 under pressure due to a breakage in the boiling water pipe 202, flowing into the gas chamber. This automatic control provides pressure protection, reducing the risk of methanol backflow. Simultaneously, this structure can automatically control the venting of residual boiling water inside the boiling water pipe 202, effectively reducing the pollution of catalyst particles caused by leakage from the boiling water pipe 202, thus reducing economic losses. The structure is more rational and can achieve automatic control, making it more suitable for high-temperature boiling water pipe protection. In the event of a leak in the boiling water pipe 202, frequent reactor start-ups and shutdowns leading to thermal stress, intensified thermal shock from localized boiling, and internal corrosion can easily cause a leak. If a leak in the boiling water pipe 202 is not detected in time, a loss of pressure inside the pipe can allow methanol synthesis gas from the main body of the reaction tower 101 to enter the boiling water pipe 202 and then the gas chamber. This synthesis gas contains flammable components such as hydrogen and carbon monoxide; after seeping into the gas chamber, it mixes with air, and if the pressure reaches the explosive limit, it can ignite upon contact with high temperature or an electrostatic spark. The system ensures that pressure is always available within the boiling water pipe 202 in the event of a leak, preventing methanol synthesis gas from seeping in. Simultaneously, it allows for the independent discharge of boiling water from the pipe 202 to prevent continuous leakage.

[0036] The radial reaction component 4 includes: an outer distribution cylinder 401, a bottom plate 4011, and a support plate 4012. The outer distribution cylinder 401 is located inside the reaction tower body 101. The bottom plate 4011 is fixedly installed at the bottom of the outer distribution cylinder 401. The bottom plate 4011 is fixedly sleeved inside the reaction tower body 101. The support plate 4012 is fixedly installed at the top of the outer distribution cylinder 401, and the support plate 4012 has a ring of slots. The support plate 4012 is sleeved inside the reaction tower body 101. The radial reaction component 4 also includes: a central distribution pipe 402 and a partition plate 403. The central distribution pipe 402... The components are fixedly installed inside the reaction tower body 101; the central distribution pipe 402 is fixedly sleeved inside the bottom plate 4011; the top of the central distribution pipe 402 is fixedly installed at the bottom of the support plate 4012; vent holes are provided on the central distribution pipe 402 and the outer distribution cylinder 401 respectively; a row of partition plates 403 is fixedly installed inside the outer distribution cylinder 401, and the row of partition plates 403 is respectively sleeved on the outside of the central distribution pipe 402; the row of partition plates 403, the bottom plate 4011 and the support plate 4012 are equidistantly distributed; the radial reaction component 4 also includes: a flange pipe 404, which is fixed on the outer distribution cylinder 401. A row of flanged pipes 404 is installed, with each flanged pipe 404 passing through the main body 101 of the reaction tower. The flanged pipes 404 are arranged in pairs, with each pair used for adding and discharging reaction particles. Flange covers are bolted to the ends of each flanged pipe 404. A ring of boiling water pipes 202 is fixedly installed on the partition plate 403, the bottom plate 4011, and the support plate 4012. Catalyst particles are filled between the partition plate 403, the bottom plate 4011, and the support plate 4012. The use of radial reaction elements 4 allows for zoned radial exhaust synthesis, ensuring... While reducing pressure resistance, the catalyst particles are used more evenly, reducing the axial movement range of methanol synthesis gas inside the catalyst particles and promoting its radial movement. When the area above the outer distribution cylinder 401 is blocked by paraffin and fine catalyst powder generated by methanol synthesis gas, the outlet resistance is greater than the inlet thrust, a large amount of airflow is blocked, which easily generates downward wind resistance and causes interference. In the actual case, when the methanol synthesis gas enters the central distribution pipe 402 from the inlet pipe 102 and flows through the catalyst particles to be discharged from the outer distribution cylinder 401, local blockage will also occur, which will be blocked by the partition plate 403.

[0037] In Example 2, based on Example 1, the sealing and blocking component 5 includes: a blocking ring 501, a sealing cylinder 502, and an electromagnet 503. A row of blocking rings 501 is fixedly sleeved inside the reaction tower body 101, and each row of blocking rings 501 is fixedly sleeved on the outer distribution cylinder 401. Each row of blocking rings 501 has a through hole. A sealing cylinder 502 is attached between the row of blocking rings 501, the bottom plate 4011, and the support plate 4012, and the row of sealing cylinders 502 is rotatably sleeved on the outer distribution cylinder 401. The sealing cylinder 502 has vent holes aligned with the outer distribution cylinder 401. Two electromagnets 503 are fixedly installed on each row of sealing cylinders 502, and the two electromagnets 503 are used to adjust the misalignment between the vent holes on the sealing cylinder 502 and the vent holes on the outer distribution cylinder 401. A row of electromagnets 503 on the right side magnetically attracts a row of flange pipes 404. The sealing and blocking component 5 can be used for external... The distribution cylinder 401 is enclosed for easy replacement of catalyst particles; each of the row of enclosed cylinders 502 has two through grooves for sliding on a row of flange pipes 404 to prevent jamming; the uniformity test piece 6 includes: a drive motor 601 and a drive screw 602, the drive motor 601 is fixedly mounted on the flange cover at the bottom of the air inlet pipe 102; the output shaft of the drive motor 601 passes through the flange cover at the bottom of the air inlet pipe 102; the drive screw 602 is fixedly mounted on the output shaft of the drive motor 601; the diameter of the drive screw 602 is smaller than the inner diameter of the air inlet pipe 102; the uniformity test piece 6 also includes: a lifting baffle 603, the lifting baffle 603 is threadedly connected to the drive screw 602, and the lifting baffle 603 has a ring of through holes; the lifting baffle 603 is slidably sleeved on the central distribution pipe 402; the length of the lifting baffle 603 is greater than the spacing between adjacent partition plates 403; the outer side of the lifting baffle 603 has a groove;The inner side of the central distribution pipe 402 is provided with a raised strip. The groove on the outer side of the lifting baffle 603 slides on the raised strip on the inner side of the central distribution pipe 402. The lifting baffle 603, together with the partition plate 403, provides separation, which facilitates the staff to quickly detect the consistency of the pressure drop and flow of catalyst particles in the central distribution pipe 402 and the outer distribution cylinder 401. This is more suitable for daily inspections and avoids the problem of difficulty in judging the flow of catalyst particles at different locations and the blockage of the central distribution pipe 402 or the outer distribution cylinder 401 by directly observing the pressure gauge. It makes it easier for staff to carry out maintenance and avoids the problem of difficulty in detecting excessive local blockage. The structure is simple and reasonable, and it also facilitates the staff to replace the catalyst particles without stopping the machine, which can ensure continuous production. This structure, employing a segmented approach, eliminates the need for complete catalyst particle replacement, resulting in a more compact and economical design. The drive motor 601 rotates the drive screw 602, causing the lifting baffle 603 to move within the central distribution pipe 402. This baffle sequentially blocks the gaps between a row of partition plates 403, the bottom plate 4011, and the support plate 4012. If each blockage results in a slight deviation in the pressure gauge 103 reading, and the deviation is roughly the same each time, it indicates minimal variation in the catalyst particle flow. However, if a blockage at a particular point causes the reading to remain unchanged or show only a small deviation, it indicates a blockage in that section. This explains why, even when blocked, the pressure within the reaction tower body 101 remains unaffected, facilitating problem identification.

[0038] The working principle of this embodiment is as follows: First, the structure is placed on the ground. When the actual methanol synthesis gas enters the central distribution pipe 402 from the inlet pipe 102 and flows through the catalyst particles to exit from the outer distribution cylinder 401, local blockage will occur. This blockage will be mitigated by the partition plate 403. The methanol synthesis gas will then exit through the through hole on the blocking ring 501 and then exit from the exhaust pipe 104. The exhaust pipe 104 can be connected to the inlet pipe of equipment such as a methanol separator for subsequent separation and other processes. During the actual synthesis reaction, the pressure gauge 103 can be used to observe the reaction process. The reaction tower body 101 is pressurized, and then the drive motor 601 is started to drive the drive screw 602 to rotate, driving the lifting baffle 603 to move inside the central distribution pipe 402. This can sequentially block the gaps between a row of partition plates 403, the bottom plate 4011, and the support plate 4012. If the pressure gauge 103 reading deviates after each blockage, and the deviation is roughly the same each time, it indicates that the airflow permeability of the catalyst particles is not significantly different. However, if the reading remains unchanged or has a small deviation after a blockage at a certain point, it indicates that... The section is already blocked, which is why even when blocked, it fails to affect the internal pressure of the reaction tower body 101. This facilitates the screening of the problem area. At the same time, the moving lifting baffle 603 is stopped at this point to block the flow. In conjunction with the control, the electromagnet 503 on the left side of the adjusting closed cylinder 502 is energized, while the electromagnet 503 on the right side is de-energized. At this time, the closed cylinder 502 rotates on the outer distribution cylinder 401. The vent holes on the closed cylinder 502 and the vent holes on the outer distribution cylinder 401 are misaligned to achieve closure. During this process, the normal operation of the through holes on the blocking ring 501 is not affected. With proper ventilation, no shutdown is required. The intake pressure can be appropriately reduced to ensure continuous production. When catalyst particles need to be replaced, the flange covers on the two corresponding flange pipes 404 can be removed normally to replace the internal catalyst particles and refill them. The operation is simple and convenient. After replacement, the lifting baffle 603 is moved down and reset, the electromagnet 503 on the right is energized, and the electromagnet 503 on the left is de-energized. The ventilation holes on the closed cylinder 502 and the ventilation holes on the outer distribution cylinder 401 are aligned, and methanol synthesis gas can flow normally for the synthesis reaction.

[0039] When a leak occurs in the boiling water pipe 202, the pressure inside the boiling water pipe 202 drops. The pressure is insufficient to push the piston 302 to compress the pressure spring 303. At this time, the piston 302, under the pressure of the pressure spring 303, will no longer compress the vent switch 304. At this time, the vent switch 304 can control the solenoid valve on the boiling water discharge pipe 203 to close to prevent backflow, the solenoid valve on the boiling water inlet pipe 204 to close to prevent backflow, and the solenoid valve on the vent pipe 205 to open, so as to independently discharge the boiling water in the boiling water pipe 202. At the same time, it controls the solenoid valve on the pressure supply pipe 206 to open to supply pressure, and controls the external air pump connected to the pressure supply pipe 206 to be energized to maintain air supply. However, the air supply pressure is insufficient to compress the pressure spring 303, ensuring that there is always pressure available in the boiling water pipe 202, preventing methanol synthesis gas from seeping into the boiling water pipe 202, and achieving independent discharge of the boiling water in the boiling water pipe 202 to prevent continuous leakage.

A ring of boiling water pipe (202) is fixedly installed between the two boiling water rectifier rings (201), and the ring of boiling water pipe (202) connects to the boiling water rectifier ring (201). The boiling water discharge pipe (203) is fixedly installed on the upper boiling water rectifier ring (201), and the boiling water discharge pipe (203) passes through the reaction tower body (101). The boiling water discharge pipe (203) has an L-shaped structure. A solenoid valve is provided on the discharge pipe (203); the boiling water discharge pipe (203) is used to connect to the steam drum return pipe; a boiling water inlet pipe (204) is fixedly installed on the lower boiling water rectifier ring (201), and the boiling water inlet pipe (204) is used to connect to the steam drum; a solenoid valve is provided on the boiling water inlet pipe (204); an empty pipe (205) is fixedly installed on the boiling water inlet pipe (204), and a solenoid valve is provided on the empty pipe (205); the empty pipe (205) receives a water collection tank; the pressure supply pipe (206) is fixedly installed on the upper boiling water rectifier ring (201); the pressure supply pipe (206) passes through the main body of the reaction tower (101); a solenoid valve is provided on the pressure supply pipe (206); an air pump is connected to the pressure supply pipe (206); The venting control component (3) includes: a pressure measuring tube (301), a piston (302), a pressure spring (303), and a venting switch (304). The pressure measuring tube (301) is fixedly installed on the upper boiling water rectifier ring (201). The piston (302) is slidably sleeved inside the pressure measuring tube (301). The pressure measuring tube (301) passes through the main body of the reaction tower (101).

At the same time, the solenoid valve on the pressure supply pipe (206) is opened to supply pressure, and the external air pump connected to the pressure supply pipe (206) is energized to maintain air supply. However, the air supply pressure is insufficient to compress the pressure spring (303), ensuring that there is always pressure in the boiling water pipe (202) to prevent methanol synthesis gas from seeping into the boiling water pipe (202). At the same time, the boiling water in the boiling water pipe (202) is independently discharged to prevent continuous leakage.
