Description

Technical Field

[0001] The present invention relates to the technical field of heat exchange devices, and particularly to a heat exchange device for an MTBE reactor. Background Art

[0002] MTBE is the trade name of methyl tert-butyl ether. Methyl tert-butyl ether is a colorless, transparent, high-octane liquid, which can be obtained by the reaction of isobutene and methanol under the catalysis of a catalyst. Its raw materials need to be heated by a heat exchange device before entering the reactor.

[0003] For example, the patent with the publication number CN117824407B: A heat exchange device for an MTBE mixed-phase bed reactor, including a reaction tank, with an inlet for the medium to be heated and an outlet for the medium to be heated respectively provided at both ends of the reaction tank. A plurality of heat exchange units are provided in the reaction tank, and a shaking unit for shaking the heat exchange units is provided on the side of the reaction tank. Through the above patent, by providing a plurality of heat exchange plates, etc., the medium to be heated is separated into multiple thin streams and moves in the flow ports, accelerating the heat exchange efficiency between the heat exchange medium and the medium to be heated. At the same time, the heat exchange plates are provided in multiple numbers and can be shaken by the shaking unit, increasing the mixing effect of the heat exchange medium, accelerating the mixing of the heat exchange medium in the middle and at the edges of the flow cavity, improving the heat conversion rate between the heat exchange medium and the medium to be heated, and the arc-shaped protrusions increase the contact area between the medium to be heated and the heat exchange medium, further improving the overall heat exchange efficiency.

[0004] However, the existing heat exchange devices for MTBE reactors still have some deficiencies in the use process. For example, after the reaction of preparing MTBE inside the MTBE reactor is stable, the temperature of the feed often needs to be reduced. When the raw material concentration is different, the temperature required for heating is also different. The method of changing the temperature of the heat exchange medium takes a long time and has low efficiency, which is not conducive to energy conservation and environmental protection. Moreover, after the heat exchange tubes are used for a long time, scale often forms on their outer walls, affecting the heat exchange efficiency, and then resulting in the heating temperature of the raw materials not reaching the expected value, affecting the output of MTBE. Summary of the Invention

[0005] The purpose of the present invention is to provide a heat exchange device for an MTBE reactor. By using this device for operation, the problems in the above background are solved, that is, after the reaction of preparing MTBE inside the MTBE reactor is stable, the temperature of the feed often needs to be reduced. When the raw material concentration is different, the temperature required for heating is also different. The method of changing the temperature of the heat exchange medium takes a long time and has low efficiency, which is not conducive to energy conservation and environmental protection. Moreover, after the heat exchange tubes are used for a long time, scale often forms on their outer walls, affecting the heat exchange efficiency, and then resulting in the heating temperature of the raw materials not reaching the expected value, affecting the output of MTBE.

A regulating component is commonly installed on each pair of the heat exchange tubes A and the heat exchange tubes B. A moving component is installed between the top surface of the T-shaped plate and the inner top wall of the housing. A bracket is fixed to the moving component. A descaling component is installed on the bracket. One side of the regulating component is fixed to the descaling component;

[0007] The regulating component includes two sliding seats respectively fixedly penetrated on the heat exchange tubes A and the heat exchange tubes B. A slot is formed in the side wall of each sliding seat. A sliding seal is installed on the inner wall of each slot, and the sliding seal is used to seal the slot. A plug is fixed to the top surface of each sliding seal. One end of each plug is grooved. The two plugs are respectively slidably sealed in the heat exchange tubes A and the heat exchange tubes B. A joint is fixed to the bottom surface of each sliding seal. The two joints are communicated through a second pipe. The joint on the same side and the plug are communicated through a first pipe.

[0008] Further, the sliding seal includes a sliding table slidably connected to the sliding seat and fixing plates fixed to both sides of the inner wall of the slot. A plurality of movable plates are stacked on the top surfaces of the two fixing plates. The plurality of movable plates on one side of each fixing plate commonly form an adjusting plate. The movable plates at both ends of each adjusting plate are respectively fixed to the fixing plate and the sliding table. The adjacent fixing plates in the up and down direction in each adjusting plate are slidably connected. Rubber pads are embedded on the side walls of each fixing plate and the movable plate.

[0009] Further, a feed pipe and a discharge pipe are fixedly penetrated and connected to the lower end of the side wall of the housing. The feed pipe is communicated with one side of the T-shaped plate inside the housing. The discharge pipe is communicated with the other side of the T-shaped plate inside the housing.

[0010] Further, a heat exchange medium inlet is penetrated through the top surface of the housing. A heat exchange medium outlet is penetrated through the lower end of the side wall of the housing. The heat exchange medium inlet and the heat exchange medium outlet are both communicated with one side of the top surface of the T-shaped plate inside the housing.

[0011] Further, the moving component includes a threaded rod rotatably connected between the top wall of the T-shaped plate and the housing, and a plurality of guide rods fixedly connected between the top wall of the T-shaped plate and the housing. A moving block is threadedly connected to the side wall of the threaded rod. The bracket is fixed to the outer wall of the moving block, and the plurality of guide rods are all slidably arranged through the bracket. A first motor is fixedly connected to the top wall of the housing, a first protective cover is fixed to the outside of the first motor, and an output shaft of the first motor is coaxially fixedly connected to one end of the threaded rod.

[0012] Further, the descaling component includes an arc-shaped frame fixed to the bracket. The arc-shaped frame is fixed to the sliding table through a connecting member. Card slots are formed in the inner ring of the arc-shaped frame, and two through holes are symmetrically formed in the side wall of each card slot.

By providing a stroke adjustment component, when the MTBE reaction reaches stability and it is necessary to reduce the feed temperature or when the raw material concentration is different and it is necessary to change the heating temperature, the first motor drives the threaded rod to rotate, so that the moving block drives the bracket to move. When the bracket moves, it drives the connected descaling component to move. The descaling component drives the sliding table to move along the strip hole, so that the plugging positions inside the heat exchange tubes A and B are changed, thereby changing the tube length of the material flowing through the heat exchange tubes A and B, making the heating time of the raw material longer or shorter to meet different heating time requirements. There is no need to change the temperature of the heat exchange medium, with high efficiency, which is beneficial to energy conservation and environmental protection, and can achieve stepless adjustment with high flexibility. After debugging, the sliding table can be accurately positioned according to the common heating time.

[0016] 2. By providing a descaling component and through the forward and reverse rotation of the first motor, the bracket can drive the descaling component to reciprocate along the outer walls of the heat exchange tubes A and B. At the same time, the second motor drives the gear to rotate. Under the meshing action of the gear and the external gear ring, the external gear ring drives the comb to rotate to remove the scale on the outer walls of the heat exchange tubes A and B, avoiding affecting the heat exchange efficiency.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0028] In order to solve the technical problems that after the reaction of preparing MTBE inside the MTBE reactor is stabilized, the temperature of the feed often needs to be lowered, and when the raw material concentration is different, the required heating temperature is also different, and the time required by changing the temperature of the heat exchange medium is relatively long and the efficiency is relatively low, the present invention provides the following preferred technical solutions:

[0029] As Figure 1 - Figure 7 shown, a heat exchange device for an MTBE reactor includes a housing 1 and a frame 2 fixed to the outer wall of the housing 1. A T-shaped plate 3 is fixed to the bottom of the inner wall of the housing 1. The T-shaped plate 3 divides the lower end of the inner wall of the housing 1 into two chambers, separating the feed from the discharge. A plurality of heat exchange tubes A4 are fixedly penetrated through one side of the top wall of the T-shaped plate 3, and a plurality of heat exchange tubes B5 are fixedly penetrated through the other side of the top wall of the T-shaped plate 3. The heat exchange tubes A4 and the heat exchange tubes B5 are arranged in pairs, and the two have the same structure. A stroke adjustment assembly 6 is commonly installed on each pair of heat exchange tubes A4 and heat exchange tubes B5 for synchronously adjusting the tube length of each pair of heat exchange tubes A4 and heat exchange tubes B5, so as to be able to adjust the heating time of the raw material according to the heating requirement and the raw material concentration. A moving assembly 7 is installed between the top surface of the T-shaped plate 3 and the inner top wall of the housing 1. A bracket 8 is fixed to the moving assembly 7, and a plurality of descaling assemblies 9 are installed on the bracket 8. The descaling assemblies 9 are respectively sleeved on the outer walls of the heat exchange tubes A4 and the heat exchange tubes B5. The descaling assemblies 9 move driven by the moving assembly 7 for removing the scale on the outer walls of the heat exchange tubes A4 and the heat exchange tubes B5. The descaling assemblies 9 are fixed to the stroke adjustment assembly 6, so that the moving assembly 7 can drive the movement of the stroke adjustment assembly 6.

[0030] The stroke adjustment assembly 6 includes two sliding seats 61 respectively fixedly penetrated through the side walls of the heat exchange tube A4 and the heat exchange tube B5. A strip hole 611 is formed in the side wall of each sliding seat 61. A sliding seal 62 is fixed to the inner wall of each strip hole 611, and the sliding seal 62 is used to seal the strip hole 611. A plug 64 is fixed to the top surface of each sliding seal 62. One end of each plug 64 is grooved. The two plugs 64 are respectively slidably sealed in the heat exchange tube A4 and the heat exchange tube B5, so as to be able to block the subsequent tube length of the heat exchange tube A4 and the heat exchange tube B5 through the plug 64 and introduce the raw material into the notch inside the plug 64. A joint 65 is fixed to the bottom surface of each sliding seal 62. The two joints 65 are connected through a second pipeline 63. The joints 65 on the same side and the plug 64 are connected through a first pipeline 66, so that the raw material enters the heat exchange tube B5 from the heat exchange tube A4, and the tube length can be changed by changing the position of the sliding seal 62, thereby realizing stepless adjustment of the heating time.

[0031] The sliding seal 62 includes a sliding table 624 slidably connected to the sliding base 61 and fixing plates 621 fixed to both sides of the inner wall of the strip hole 611. A plurality of movable plates 622 are stacked on the top surfaces of the two fixing plates 621. The plurality of movable plates 622 on one side of each fixing plate 621 together form an adjusting plate. The movable plates 622 at both ends of each adjusting plate are respectively fixedly connected to the fixing plate 621 and the sliding table 624. The two adjacent fixing plates 621 in the vertical direction of each adjusting plate are slidably connected. When the sliding table 624 moves, it drives the movable plates 622 to move so as to contract or expand, so that the strip hole 611 is always in a sealed state. Rubber pads 623 are embedded on the side walls of each fixing plate 621 and the movable plates 622. The rubber pads 623 are in close contact with the strip hole 611 and slide, further strengthening the seal at the strip hole 611 when the movable plates 622 slide.

[0032] A feed pipe 11 and a discharge pipe 12 are fixedly connected through the lower end of the side wall of the housing 1. The feed pipe 11 communicates with one side of the T-shaped plate 3 inside the housing 1, and the discharge pipe 12 communicates with the other side of the T-shaped plate 3 inside the housing 1. The MTBE raw material enters one side of the T-shaped plate 3 inside the housing 1 through the feed pipe 11, and then sequentially enters the heat exchange tubes A4 and B5 for heat exchange, and then enters the other side of the T-shaped plate 3 and is output to the MTBE reactor through the discharge pipe 12.

[0033] A heat exchange medium inlet 13 is provided through the top surface of the housing 1, and a heat exchange medium outlet 14 is provided through the lower end of the side wall of the housing 1. Both the heat exchange medium inlet 13 and the heat exchange medium outlet 14 communicate with one side of the top surface of the T-shaped plate 3 inside the housing 1. The heat exchange medium enters through the heat exchange medium inlet 13, passes through the shell side, and finally discharges from the heat exchange medium outlet 14, and circulates in this way.

[0034] The moving assembly 7 includes a threaded rod 71 rotatably connected between the top wall of the T-shaped plate 3 and the housing 1 and a plurality of guide rods 72 fixedly connected between the top wall of the T-shaped plate 3 and the housing 1. A moving block 73 is threadedly connected to the side wall of the threaded rod 71. The bracket 8 is fixed to the outer wall of the moving block 73, and the plurality of guide rods 72 are all slidably arranged through the bracket 8. A first motor 74 is fixedly connected to the top wall of the housing 1. A first protective cover 75 is fixed to the outside of the first motor 74. The output shaft of the first motor 74 is coaxially fixedly connected to one end of the threaded rod 71. The first motor 74 can drive the threaded rod 71 to rotate, and then drive the descaling assembly 9 and the stroke adjusting assembly 6 to move through the moving block 73.

[0035] Specifically, during operation, the heat exchange tube A4, the first pipeline 66, the second pipeline 63 and the heat exchange tube B5 form a U-shaped bent tubular channel. The raw material is input through the feed pipe 11, enters the notch of the plug 64 through the heat exchange tube A4, then enters the heat exchange tube B5 through the first pipeline 66 and the second pipeline 63, and finally is output to the reactor through the discharge pipe 12. A large amount of fluid heat exchange medium enters through the heat exchange medium inlet 13, passes through the shell side, and finally is discharged through the heat exchange medium outlet 14. When the MTBE reaction reaches a stable state and it is necessary to reduce the feed temperature or change the heating temperature due to different raw material concentrations, the prior art takes a relatively long time and has low efficiency by changing the temperature of the heat exchange medium. At this time, the first motor 74 is driven to rotate the threaded rod 71, so that the moving block 73 drives the bracket 8 to move. When the bracket 8 moves, it drives the descaling assembly 9 connected thereto to move. The descaling assembly 9 drives the sliding table 624 to move along the strip hole 611, and the position of the plug 64 inside the heat exchange tube A4 and the heat exchange tube B5 changes, thereby changing the tube length of the material flowing through the heat exchange tube A4 and the heat exchange tube B5, making the heating time of the raw material longer or shorter to meet different heating time requirements, and enabling stepless adjustment with high flexibility. Moreover, after debugging, the sliding table 624 can be accurately positioned according to the common heating time. When the sliding table 624 moves, it drives the movable plates 622 on both sides thereof to slide, so that they extend or retract according to the moving direction of the sliding table 624, making the strip hole 611 always in a closed state, and tightly abutting and sliding with the strip hole 611 through the rubber pad 623, further strengthening the sealing at the strip hole 611 when the movable plate 622 slides.

[0036] In order to solve the technical problem that after the heat exchange tube is used for a long time, scale often forms on its outer wall, affecting the heat exchange efficiency, and further causing the heating temperature of the raw material to fail to reach the expected value, affecting the output of MTBE, the present invention provides the following preferred technical solutions:

[0037] As Figure 7 - Figure 9 As shown, the descaling assembly 9 includes an arc-shaped frame 91 fixed on the bracket 8. The arc-shaped frame 91 enables the heat exchange tube A4 and the heat exchange tube B5 to be clamped through its own notch. The arc-shaped frame 91 and the sliding table 624 are fixed through a connecting member 92. A clamping groove 911 is formed in the inner circle of the arc-shaped frame 91, through holes 912 are symmetrically formed in the side wall of the clamping groove 911, and an external gear ring 93 is rotatably installed in the clamping groove 911. Comb teeth 931 are provided on the inner circle of the external gear ring 93. When adjusting the tube length of the heat exchange tube A4 and the heat exchange tube B5, the comb teeth 931 on the inner circle of the external gear ring 93 slide up and down along the outer walls of the heat exchange tube A4 and the heat exchange tube B5, achieving the effect of cleaning the outer walls of the heat exchange tubes, and reducing the generation of scale on the outer walls of the heat exchange tube A4 and the heat exchange tube B5 during operation.

[0038] One end of the outer side of the through hole 912 is fixedly connected with a second protective cover 94. A gear 95 is rotatably connected to the inner wall of the second protective cover 94. The gear 95 is meshed and driven with an external gear ring 93. The top wall of the second protective cover 94 is fixedly connected with a second motor 96. The output shaft of the second motor 96 is coaxially and fixedly connected with one end of the rotating shaft of the gear 95. The second motor 96 is used to drive the gear 95 to rotate. Through the meshing drive between the gear 95 and the external gear ring 93, the external gear ring 93 can drive the comb teeth 931 to rotate. During shutdown maintenance, through the rotation of the external gear ring 93, the comb teeth 931 are used to remove the scale on the outer walls of the heat exchange tubes A4 and B5 along the circumferential direction, avoiding excessive scale from affecting the heat exchange efficiency during operation, and also being able to avoid the scale from corroding the tube walls.

[0039] Specifically, after long-term use, the outer walls of the heat exchange tubes A4 and B5 often scale, resulting in a reduction in heat exchange efficiency and requiring timely cleaning. During maintenance, through the forward and reverse rotation of the first motor 74, the bracket 8 can drive the descaling assembly 9 to reciprocate along the outer walls of the heat exchange tubes A4 and B5. At the same time, the second motor 96 drives the gear 95 to rotate. Under the meshing action between the gear 95 and the external gear ring 93, the external gear ring 93 drives the comb teeth 931 to rotate to remove the scale on the outer walls of the heat exchange tubes A4 and B5, avoiding affecting the heat exchange efficiency.
