Description

Technical Field

[0001] This invention belongs to the field of regenerative furnace technology, specifically a modular plate regenerator quick-assembly structure for a regenerative thermal oxidation furnace. Background Technology

[0002] A regenerative thermal oxidizer (RTO) is an energy-saving and environmentally friendly device that uses a heat storage medium to recover the heat from the oxidation and decomposition of organic waste gas. Plate-type heat storage media are widely used due to their advantages such as large specific surface area, low airflow resistance, and high heat exchange efficiency.

[0003] Currently, the main installation methods for plate-type thermal regenerators in the thermal regenerator chamber include bottom grid support, side wall angle steel support, and bolt-pressed plate installation. Their common characteristic is that several thermal regenerator modules need to be arranged in layers on the same plane, and then stacked again on top of each other. However, this stacking method leads to misalignment of the channels in the vertical direction of the plate-type thermal regenerator modules. This causes high-temperature exhaust gas to preferentially pass through the gaps of least resistance or reduces the efficiency of exhaust gas passage, resulting in some thermal regenerators not being effectively utilized, leading to a decrease in heat exchange efficiency. Therefore, to reduce the misalignment between the seams, a significant amount of time is required for re-arranging.

[0004] Meanwhile, with all layers stacked, the bottom heat storage module bears enormous static pressure. In addition, dust particles carried in the flue gas will gradually accumulate in the microchannels of the plates, increasing the pressure drop. If the bottom grille or angle steel support softens and deforms due to high temperature, it will cause problems such as overall tilting or even collapse.

[0005] Therefore, based on the above problems, a modular plate regenerator quick-assembly structure for a regenerative thermal oxidizer is proposed. Summary of the Invention

[0006] To address the problems mentioned in the background art, the present invention provides a modular plate heat exchanger quick-assembly structure for a regenerative thermal oxidizer, which solves the problems of reduced heat exchange efficiency caused by misalignment of heat exchanger module channels in different layers during heat exchanger module installation, and low installation efficiency caused by the large amount of time required for arranging to reduce the degree of misalignment.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a modular plate heat storage quick-assembly structure for a regenerative thermal oxidizer, comprising a heat storage furnace body and a heat storage chamber installed thereon, and further comprising: a heat storage module installed in the heat storage chamber, wherein two sets of support mechanisms are installed on the front and rear side walls of the heat storage chamber. The support mechanism includes a frame fixedly installed on the heat storage chamber. The frame is vertically equidistantly connected to several support members by springs. A tension spring top rod located between two adjacent support members is movably installed inside the frame. A hemisphere is fixedly installed on the top of the tension spring top rod. The hemisphere is movably installed in the support member at the corresponding height in the initial state. Initially, the top of the bottom support is located outside the heat storage chamber, and all other support members except the bottom support are located inside the frame. The bottom of the support member is also provided with a protrusion that abuts against the bottom of the tension spring rod. When the support member rotates downward, the protrusion on it can push the tension spring rod upward.

[0008] Preferably, the top of the support member is arc-shaped, and after the support member is rotated to the horizontal direction, its lower surface will be in contact with the bottom of the frame.

[0009] Preferably, the heat storage module includes a frame, with perforated partitions fixedly installed at the top and bottom of the frame, and a plate-type heat storage body installed between two of the perforated partitions; The frame can be placed inside the heat storage chamber.

[0010] Preferably, the vertical distance between the two support members is greater than the height of the frame.

[0011] Preferably, several wedge-shaped guide positioning modules for guiding and positioning the heat storage module in the front-back direction are vertically and equidistantly installed on the left and right walls of the heat storage chamber.

[0012] Preferably, the wedge-shaped guide positioning module includes a connecting plate rotatably connected to the heat storage chamber. The top and bottom ends of the connecting plate are hinged with connecting rods. The ends of the two sets of connecting rods away from the connecting plate are hinged with wedge-shaped guide blocks. The two sets of wedge-shaped guide blocks are respectively movably installed on the front and rear walls of the heat storage chamber and located above the corresponding support members. A spring floating guide member with an upward tendency due to its own elastic force is movably installed on the wedge-shaped guide block. A one-way locking pin that can be unidirectionally locked into the heat storage chamber cavity is fixedly installed on the top of the spring floating guide member. The one-way locking pin can move outward in one direction only; Initially, the wedge-shaped guide block is subjected to the elastic force of a spring on it, which allows the inclined portion of the wedge-shaped guide block to be located in the cavity of the heat storage chamber.

[0013] Preferably, the front and rear walls of the heat storage chamber are vertically and equidistantly equipped with a plurality of locking components corresponding to the wedge-shaped guide blocks located below them for locking the wedge-shaped guide blocks in the horizontal direction.

[0014] Preferably, the shaft portion of the support member extends through the frame, and the bottom of the wedge-shaped guide block is provided with several toothed grooves at equal intervals; The locking assembly includes a drive shaft fixedly installed at one end of the shaft portion of the support member. A cam is fixedly sleeved on the outer periphery of the drive shaft. A spring combination locking pin, which has an upward tendency due to the action of its own spring portion, is movably installed on the heat storage chamber. The top end of the spring combination locking pin can be engaged in the tooth groove initially. When the cam rotates around the axis, it can abut against the bottom end of the spring combination locking pin. At this time, the top end of the spring combination locking pin is stuck in the tooth groove and cannot move downward.

[0015] Preferably, in the initial state, there is a gap between the bottom end of the spring combination locking pin and the outer periphery of the cam component. After the support component is rotated to a horizontal state, the cam component will abut against the bottom end of the spring combination locking pin.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The above-described solution involves first assembling the plate-type regenerators in layers on the outside of the regenerator body within a frame. The frame is then lowered into the regenerator chamber from top to bottom using a hoisting device. As the frame descends to its lowest point, its bottom edge abuts against the top of a support component. The support component deflects downwards to a horizontal position during the frame's descent, thus enabling rapid installation of the regenerator modules. During this process, the shaft of the support component pushes a tension spring rod, causing the hemisphere to rise. The rising hemisphere compresses the corresponding support component, causing it to deflect outwards. This facilitates the operator's rapid assembly of the next set of regenerator modules. The above solution works by having the bottom of the frame first contact the top slope of the spring floating guide when it descends, causing it to move downwards and disengage the one-way latch from the heat storage chamber. When all the spring floating guides that the frame is in contact with descend and the one-way latches disengage from their upper one-way slots, the frame continues to descend. At this time, the side wall of the frame will contact the end of the wedge-shaped guide block. When the bottom of the frame first contacts the spring floating guide on one side and moves downwards, the top of the one-way latch corresponding to the bottom of the other side of the frame has not yet disengaged from its upper slot. At this time, the spring floating guide that is in contact with the bottom of the frame will remain stationary and force the frame to move to the other side, thereby ensuring that the frame is in the middle position of the heat storage chamber. The above solution works by forcing the support to rotate at the bottom during the assembly of the frame. The shaft of the support will also drive the transmission shaft and cam to rotate, and the outer periphery of the cam will abut against the bottom end of the spring combination locking pin. At this time, the top of the spring combination locking pin cannot descend and disengage from the tooth groove. Meanwhile, the wedge-shaped guide block will limit the side of the frame during subsequent operation, reducing the probability of the heat storage module becoming loose due to vibration or airflow pulsation during the operation of the device.

[0019] 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.

[0020] like Figures 1 to 9 As shown, the present invention provides a modular plate heat storage quick-assembly structure for a regenerative thermal oxidizer, including a heat storage furnace body 6 and a heat storage chamber 1 installed thereon, and further including: a heat storage module 2 installed in the heat storage chamber 1, and two sets of support mechanisms 3 are installed on the front and rear side walls of the heat storage chamber 1. The support mechanism 3 includes a frame 31 fixedly installed on the heat storage chamber 1. The frame 31 is vertically equidistant and connected by a number of support members 33 by springs. A tension spring rod 32 located between two adjacent support members 33 is movably installed inside the frame 31. A hemisphere 34 is fixedly installed on the top of the tension spring rod 32. The hemisphere 34 is movably installed in the support member 33 at the corresponding height in the initial state. Initially, the top of the support member 33 at the bottom is located outside the heat storage chamber 1, and all the other support members 33 except the bottom support member 33 are located in the frame 31. The bottom of the support member 33 is also provided with a protrusion that abuts against the bottom of the tension spring rod 32. When the support member 33 rotates downward, the protrusion on it can push the tension spring rod 32 upward. The top of the support member 33 is arc-shaped. After the support member 33 is rotated to the horizontal direction, its lower surface will be in contact with the bottom of the frame 31. The heat storage module 2 includes a frame 21, with perforated partitions 23 fixedly installed at the top and bottom of the frame 21, and a plate-type heat storage body 22 installed between the two perforated partitions 23; the frame 21 can be placed into the heat storage chamber 1. Using the above scheme, the plate-type heat storage body 22 is first assembled in layers on the outside of the heat storage furnace body 6 and then assembled in the frame 21. The frame 21 is then lowered into the heat storage chamber 1 from top to bottom using a hoisting device. After the frame 21 descends to the bottom, its bottom edge abuts against the top of the support member 33. The support member 33 deflects downward to a horizontal state during the descent of the frame 21, thereby achieving rapid installation of the heat storage body module 2. During this process, the shaft of the support member 33 pushes the tension spring rod 32 to drive the hemisphere 34 upward. The upward movement of the hemisphere 34 compresses the corresponding support member 33, causing it to deflect outward. This facilitates the operator to quickly assemble the next set of heat storage body modules 2. Since the vertical distance between the two support members 33 is greater than the height of the frame 21, after several sets of heat storage body modules 2 are assembled, there is a vertical distance between the two heat storage body modules 2, thus avoiding the problem of misalignment of the two sets of heat storage body channels in the vertical direction, which would reduce the exhaust gas throughput.

[0021] like Figures 3-5 and Figures 7-9 As shown, several wedge-shaped guide positioning modules 4 are vertically and equidistantly installed on the left and right walls of the heat storage chamber 1 for guiding and positioning the heat storage module 2 in the front-back direction. The wedge-shaped guide positioning module 4 includes a connecting plate 41 rotatably connected to the heat storage chamber 1. The top and bottom ends of the connecting plate 41 are hinged with connecting rods 42. The ends of the two sets of connecting rods 42 away from the connecting plate 41 are hinged with wedge-shaped guide blocks 43. The two sets of wedge-shaped guide blocks 43 are respectively movably installed on the front-back walls of the heat storage chamber 1 and are located above the corresponding support members 33. A spring floating guide member 44 with an upward tendency due to its own elastic force is movably installed on the wedge-shaped guide block 43. A one-way locking pin 45 that can be unidirectionally inserted into the cavity of the heat storage chamber 1 is fixedly installed on the top of the spring floating guide member 44. The one-way locking pin 45 can move outward in one direction. Initially, the wedge-shaped guide block 43 will be subject to the elastic force of the spring set on it, so that the inclined part of the wedge-shaped guide block 43 is located in the cavity of the heat storage chamber. Using the above scheme, when the frame 21 moves downward, its bottom end first abuts against the top inclined surface of the spring floating guide 44, causing it to move downward and drive the one-way latch 45 to disengage from the heat storage chamber 1. When all the spring floating guides 44 abutting the frame 21 move downward and cause the one-way latch 45 to disengage from the one-way slot above them, the frame 21 will continue to move downward. At this time, the side wall of the frame 21 will abut against the end of the wedge-shaped guide block 43. When the bottom end of the frame 21 abuts against the spring floating guide 44 on one side and moves downward, the top of the one-way latch 45 corresponding to the bottom of the other side of the frame 21 has not yet disengaged from the slot above it. At this time, the spring floating guide 44 abutting against the bottom of the frame 21 will remain stationary and force the frame 21 to move to the other side, thereby ensuring that the frame 21 is in the middle position of the heat storage chamber 1.

[0022] like Figure 3 , Figure 6 , Figure 7 and Figure 9 As shown, several locking components 5 are installed vertically at equal intervals on the front and rear walls of the heat storage chamber 1, corresponding to the wedge-shaped guide blocks 43 located below them, for locking the wedge-shaped guide blocks 43 in the horizontal direction; the shaft portion of the support member 33 passes through the frame 31, and several toothed grooves 431 are equally spaced at the bottom of the wedge-shaped guide blocks 43. The locking assembly 5 includes a drive shaft 51 fixedly installed at one end of the shaft portion of the support member 33. A cam member 52 is fixedly sleeved on the outer periphery of the drive shaft 51. A spring combination locking pin 53 with an upward tendency due to the action of its own spring portion is movably installed on the heat storage chamber 1. The top end of the spring combination locking pin 53 can be engaged in the tooth groove 431 at the beginning. When the cam 52 rotates around the axis, it can abut against the bottom end of the spring combination locking pin 53. At this time, the top end of the spring combination locking pin 53 is stuck in the tooth groove 431 and cannot move downward. By adopting the above scheme, when the bottom of the frame 21 is forced to rotate during the assembly process, the shaft part of the support 33 will also drive the transmission shaft 51 and the cam 52 to rotate, and the outer periphery of the cam 52 will abut against the bottom end of the spring combination locking pin 53. At this time, the top end of the spring combination locking pin 53 cannot descend and disengage from the tooth groove 431. At this time, the wedge guide block 43 will play a limiting role on the side of the frame 21 during subsequent operation, reducing the probability of the heat storage module 2 becoming loose due to vibration or airflow pulsation during the operation of the device.

[0023] It should be noted that in the initial state, there is a gap between the bottom end of the spring combination locking pin 53 and the outer periphery of the cam member 52. After the support member 33 is rotated to the horizontal state, the cam member 52 will abut against the bottom end of the spring combination locking pin 53, thereby ensuring that when the frame 21 moves downward, the tooth groove 431 can squeeze the top end of the spring combination locking pin 53 to make it move downward, avoiding the situation where the wedge guide block 43 cannot move due to the jamming between the tooth groove 431 and the top end of the spring combination locking pin 53. Working principle and usage process of this invention: In use, the plate-type heat storage body 22 is first assembled in layers on the outside of the heat storage furnace body 6 and then assembled in the frame 21. The frame 21 is then lowered into the heat storage chamber 1 from top to bottom using a hoisting device. After the frame 21 descends to the bottom, the bottom edge of the frame 21 will abut against the top of the support member 33. The support member 33 deflects downward to a horizontal state during the descent of the frame 21, thereby realizing the rapid installation of the heat storage body module 2. During this process, the shaft part of the support member 33 will push the tension spring top rod 32 to drive the hemisphere 34 upward. The upward movement of the hemisphere 34 will compress the corresponding support member 33 to deflect outward, which facilitates the operator to quickly assemble the next set of heat storage body modules 2. As the frame 21 descends, its bottom end first abuts against the top inclined surface of the spring floating guide 44, causing it to descend and drive the one-way latch 45 to disengage from the heat storage chamber 1. When all the spring floating guides 44 abutting the frame 21 descend and cause the one-way latch 45 to disengage from the one-way slot above them, the frame 21 will continue to descend. At this time, the side wall of the frame 21 will abut against the end of the wedge-shaped guide block 43. When the bottom end of the frame 21 abuts against the spring floating guide 44 on one side and causes it to descend, the top end of the one-way latch 45 corresponding to the bottom of the other side of the frame 21 has not yet disengaged from the slot above it. At this time, the spring floating guide 44 abutting against the bottom of the frame 21 will remain stationary and force the frame 21 to move to the other side, thereby ensuring that the frame 21 is in the middle position of the heat storage chamber 1. During the assembly of the heat storage module 2, when the bottom of the frame 21 forces the support 33 to rotate, the shaft of the support 33 will also drive the transmission shaft 51 and the cam 52 to rotate, and the outer periphery of the cam 52 will abut against the bottom end of the spring combination locking pin 53. At this time, the top end of the spring combination locking pin 53 cannot descend and disengage from the tooth groove 431. At this time, the wedge guide block 43 will play a limiting role on the side of the frame 21 during subsequent operation, reducing the probability of the heat storage module 2 becoming loose due to vibration or airflow pulsation during the operation of the device.
