Description

Technical Field

[0001] The present invention relates to the field of condensers, and in particular to an energy-saving and highly efficient flue gas condenser. Background Art

[0002] Flue gas condensers are commonly used for heat recovery of high-temperature flue gas generated by boiler combustion, which can effectively save production costs and improve the thermal efficiency of boilers.

[0003] A Chinese patent with the publication number CN101221021B discloses a flue gas condenser, which includes a housing. The housing is provided with a flue gas inlet, a flue gas outlet, a cooling water inlet and a cooling water outlet. A coiled capillary tube is arranged between the cooling water inlet and the cooling water outlet.

[0004] The flow rate of the cooling water in the above-mentioned coiled capillary tube is relatively fast. Therefore, the cooling water may flow out of the coiled capillary tube before fully absorbing the heat of the flue gas, resulting in a low recovery rate of the heat of the flue gas. Summary of the Invention

[0005] In order to improve the recovery rate of the heat of the flue gas, the present application provides an energy-saving and highly efficient flue gas condenser.

[0006] The energy-saving and highly efficient flue gas condenser provided by the present application adopts the following technical solutions:

[0007] An energy-saving and highly efficient flue gas condenser includes an inner tube. A plurality of partition strips are circumferentially arranged on the outer side wall of the inner tube. A first arc plate is closely attached between two adjacent partition strips. The inner tube, the first arc plate and the two adjacent partition strips form a heat absorption cavity for the cooling water to absorb the heat of the flue gas. The end faces of the first arc plate, the inner tube and the partition strips are coplanar; one end of the inner tube is communicated with a water inlet cylinder, and the other end is communicated with a water outlet cylinder. The water inlet cylinder is communicated with a water inlet pipe. Through holes for communication are opened at positions of the water inlet cylinder corresponding to each heat absorption cavity. Drain valves are arranged at positions of the water outlet cylinder corresponding to each heat absorption cavity. A plurality of drain valves are electrically connected to a control system. The water outlet cylinder is communicated with a water outlet pipe.

[0008] By adopting the above technical solutions, the cooling water flows into the water inlet cylinder from the water inlet pipe, and then flows into each heat absorption cavity in sequence. The high-temperature flue gas enters the inner tube from the water outlet cylinder. During the process of flowing in the inner tube, the heat of the flue gas is absorbed by the cooling water in the heat absorption cavity, and then flows out from the water inlet cylinder. Under the control of the control system, each drain valve is opened in sequence, so as to achieve drainage while replenishing water in sequence. Through the above method, the heat absorption cavity can fully absorb heat before discharging the cooling water, which is beneficial to improving the recovery rate of the heat of the flue gas.

[0009] Optionally, receiving grooves are formed at positions of the water inlet cylinder corresponding to each heat absorption cavity. A floating plate is slidably engaged between the receiving groove and the corresponding heat absorption cavity. The floating plate is in close contact with each side wall of the corresponding heat absorption cavity. An inlet valve electrically connected to the control system is provided on the floating plate.

[0010] By adopting the above technical solution, during drainage, the control system opens the drain valve. At this time, the cooling water below the floating plate flows out of the heat absorption cavity, and the height of the floating plate gradually decreases. At the same time, the cooling water in the water inlet cylinder flows into the heat absorption cavity. After all the cooling water that has fully absorbed heat is drained, the control system closes the drain valve and opens the inlet valve. At this time, the cooling water above the floating plate flows through the inlet valve to the lower part of the floating plate. In this way, the floating plate floats under the buoyancy of the cooling water until the floating plate is completely located in the receiving groove again. During the above drainage and water replenishment processes, the fully heat-absorbed cooling water and the unabsorbed cooling water do not mix, which is beneficial to improving the heat recovery effect of the cooling water on the flue gas heat.

[0011] Optionally, deformation grooves communicating with each heat absorption cavity are formed at positions of the inner tube corresponding to each heat absorption cavity. An elastic water bag is provided in the deformation groove. The first arc plate is slidably engaged with the partition strip. A driving assembly for driving the first arc plate to move along a direction close to or away from the axis of the inner tube and a turnover assembly for driving the driving assembly to rotate circumferentially around the axis of the inner tube are further provided outside the inner tube.

[0012] By adopting the above technical solution, under the action of the turnover assembly, the driving assembly rotates circumferentially. When the driving assembly moves to the corresponding position, it drives the first arc plate to move along a direction close to the axis of the inner tube, so that part of the heat absorption cavity can be squeezed into the elastic water bag. The elastic water bag deforms towards the inner tube, so as to be in direct contact with the high-temperature flue gas in the inner tube, which is beneficial to improving the heat absorption effect of the cooling water on the flue gas heat.

[0013] Optionally, a second arc plate is provided on the side of the first arc plate facing away from the axis of the inner tube. A bearing rod is provided between the first arc plate and the second arc plate. The driving assembly includes guide blocks respectively arranged on both arc-shaped sides of the first arc plate. A sliding groove for the guide blocks to slide is formed on the side wall of the partition strip. A compression spring is propped between one end of the sliding groove relative to the axis of the inner tube and the guide block. The driving assembly further includes a bearing ring that is at the same level as and in close contact with the second arc plate. The distance between the inner side wall of the bearing ring and the axis of the inner tube is equal to the distance between the outer side wall of the partition strip and the axis of the inner tube. A notch is formed on the bearing ring, and a bearing plate is provided directly below the notch. A first motor electrically connected to the control system is provided on the bearing plate. A runner is fixedly sleeved on the output shaft of the first motor. The runner is eccentrically arranged with the output shaft of the first motor and the runner abuts against the outer arc surface of the second arc plate.

[0014] By adopting the above technical solution, the output shaft of the first motor drives the runner to rotate. Since the runner is eccentrically arranged with the output shaft of the first motor, during the rotation process, the first arc plate can be pushed to move towards the direction close to the axis of the inner tube through the second arc plate and the bearing rod. At the same time, during the rotation of the runner, the deformation force of the compression spring can push the first arc plate to move along the direction away from the axis of the inner tube, so that the cooling water in the elastic water bag flows back into the heat absorption cavity.

[0015] Optionally, the turnover assembly includes a second motor electrically connected to the control system, a sprocket fixedly sleeved on the output shaft of the second motor, a chain ring rotatably sleeved outside several of the partition strips, and a chain sleeved between the chain ring and the sprocket. A support rod is provided between the chain ring and the bearing ring.

[0016] By adopting the above technical solution, the output shaft of the second motor drives the chain ring to rotate through the sprocket and the chain, and the chain ring drives the bearing ring to rotate through the support rod, so as to realize the turnover of the drive assembly.

[0017] Optionally, a liquid level sensor electrically connected to the control system is provided in the water inlet cylinder, and an exhaust hole is further opened at the top of the water inlet cylinder.

[0018] By adopting the above technical solution, the liquid level sensor can detect the water level in the water inlet cylinder. When the water level is too low, the liquid level sensor can timely send a signal for water replenishment to the control system.

[0019] Optionally, when the distance between the first arc plate and the axis of the inner tube is the smallest, the communicating part between the drain valve and the heat absorption cavity is located on the side of the first arc plate facing the inner tube.

[0020] By adopting the above technical solution, in this way, regardless of whether the drive assembly operates or not, the drain valve can drain the cooling water in the corresponding heat absorption cavity.

[0021] Optionally, a corrugated heat conduction tube in a tubular shape is provided in the inner tube.

[0022] By adopting the above technical solution, during the deformation process of the elastic water bag into the inner tube, the elastic water bag will tend to deform towards the heat conduction tube, which is beneficial to increasing the contact area between the elastic water bag and the high-temperature flue gas, thereby improving the heat recovery effect of the cooling water on the flue gas heat.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Cooling water flows into the water inlet cylinder from the water inlet pipe, and then flows into each heat absorption cavity in sequence. High-temperature flue gas enters the inner pipe from the water outlet cylinder. During the flow in the inner pipe, the heat is absorbed by the cooling water in the heat absorption cavity, and then flows out from the water inlet cylinder. Under the control of the control system, each drain valve is opened in sequence, so as to achieve drainage while replenishing water in sequence. Through the above method, the heat absorption cavity can fully absorb heat before discharging, which is beneficial to improving the recovery utilization rate of flue gas heat;

[0025] 2. During the process of the heat absorption cavity realizing drainage and water replenishment, the fully heat-absorbed cooling water and the unabsorbed cooling water will not be mixed, which is beneficial to improving the heat recovery effect of the cooling water on the flue gas heat;

[0026] 3. Under the action of the turnover assembly, the driving assembly rotates circumferentially. When the driving assembly moves to the corresponding position, the first arc plate is driven to move along the direction close to the axis of the inner pipe, so as to squeeze part of the inside of the heat absorption cavity into the elastic water bag. The elastic water bag deforms into the inner pipe, so as to be in direct contact with the high-temperature flue gas in the inner pipe, which is beneficial to improving the heat absorption effect of the cooling water on the flue gas heat.

Detailed Embodiment

[0031] The following is a further detailed description of the present application in conjunction with the attached Figures 1-3 to further illustrate the present application.

[0032] The embodiment of the present application discloses an energy-saving and highly efficient flue gas condenser.

[0033] Refer to Figure 1 and Figure 2 , the energy-saving and high-efficiency flue gas condenser includes an inner tube 1 arranged vertically. A plurality of partition strips 2 are circumferentially arranged on the outer side wall of the inner tube 1. The partition strips 2 are made of heat-insulating materials. A first arc plate 3 is closely attached between two adjacent partition strips 2. Both the first arc plate 3 and the partition strips 2 are parallel to the axis direction of the inner tube 1.

[0034] Refer to Figure 1 , a heat absorption cavity 4 for the cooling water to absorb the heat of the flue gas is formed between the inner tube 1, the first arc plate 3 and the two partition strips 2 adjacent to the first arc plate 3. The end faces of the first arc plate 3, the inner tube 1 and the partition strips 2 are coplanar. The inner tube 1 is made of heat-conducting materials, while the first arc plate 3 and the partition strips 2 are both made of heat-insulating materials.

[0035] Refer to Figure 1 and Figure 2 , one end of the inner tube 1 is welded with a water inlet cylinder 5, and the other end is welded with a water outlet cylinder 6. Both the water inlet cylinder 5 and the water outlet cylinder 6 are made of heat-insulating materials. Both the water inlet cylinder 5 and the water outlet cylinder 6 are annularly arranged and hollow inside. The high-temperature flue gas flows into the inner tube 1 through the water outlet cylinder 6, and after being absorbed heat in the inner tube 1, it is discharged from the water inlet cylinder 5.

[0036] The inner cavity of the water inlet cylinder 5 is communicated with a water inlet pipe 7. Through holes (not shown in the figure) for communication are opened at positions of the water inlet cylinder 5 corresponding to each heat absorption cavity 4. Drain valves 8 are threadedly connected to the water outlet cylinder 6 at positions corresponding to each heat absorption cavity 4. A plurality of drain valves 8 are electrically connected to the control system. The water outlet cylinder 6 is communicated with a water outlet pipe 9.

[0037] Refer to Figure 1 and Figure 2 , the cooling water enters the water inlet cylinder 5 through the water inlet pipe 7, and then flows into the corresponding heat absorption cavity 4 through the through holes, and the plurality of heat absorption cavities 4 are filled with water in sequence. During the process of filling water in one heat absorption cavity 4, the cooling water in the remaining heat absorption cavities 4 has sufficient time to absorb the heat of the high-temperature flue gas in the inner tube 1, which is beneficial to improving the recovery and utilization effect of the flue gas heat.

[0038] Refer to Figure 2 , a liquid level sensor 17 electrically connected to the control system is threadedly connected inside the water inlet cylinder 5, and an exhaust hole 501 is also opened at the top end of the water inlet cylinder 5. The liquid level sensor 17 can detect the water volume of the cooling water in the water inlet cylinder 5, so that when the water level in the water inlet cylinder 5 is too low, a signal for replenishing water can be sent out in time.

[0039] Refer to Figure 2 and Figure 3, a receiving groove (not shown in the figure) is provided at the position of the water inlet cylinder 5 corresponding to each heat absorption cavity 4. A floating plate 10 is slidably fitted between the receiving groove and the corresponding heat absorption cavity 4. The floating plate 10 is in close contact with each side wall of the corresponding heat absorption cavity 4. An inlet valve 11 electrically connected to the control system is provided on the floating plate 10.

[0040] When the heat absorption cavity 4 is filled with cooling water, the floating plate 10 is located in the receiving groove and the inlet valve 11 is inserted into the through hole. When the drain valve 8 drains water, the floating plate 10 will gradually lower until all the cooling water in the heat absorption cavity 4 is drained.

[0041] At this time, the control system closes the drain valve 8 and opens the inlet valve 11, so that the cooling water above the floating plate 10 can flow to the lower part of the floating plate 10, and the floating plate 10 moves upward back into the receiving groove under the action of buoyancy.

[0042] By the above method, the heat absorption cavity 4 is drained and replenished with water. During the process of draining and replenishing water, the heated cooling water and the unheated cooling water will not be mixed, which is beneficial to improving the recovery effect of the cooling water on the heat of the flue gas.

[0043] Refer to Figure 2 and Figure 3 , deformation grooves 101 communicating with each heat absorption cavity 4 are provided at the positions of the inner tube 1 corresponding to each heat absorption cavity 4. Elastic water bags 12 are bonded in the deformation grooves 101. The first arc plate 3 is slidably fitted with the partition strip 2. A driving assembly 15 for driving the first arc plate 3 to move along the direction close to or away from the axis of the inner tube 1 and a turnover assembly 16 for driving the driving assembly 15 to rotate circumferentially around the axis of the inner tube 1 are further provided outside the inner tube 1.

[0044] When the heat absorption cavity 4 is filled with water, under the action of the turnover assembly 16, the driving assembly 15 rotates circumferentially around the axis of the inner tube 1. When the driving assembly 15 moves in place, the driving assembly 15 drives the first arc plate 3 to move towards the direction close to the axis of the inner tube 1, so that a part of the cooling water in the heat absorption cavity 4 is pushed into the elastic water bag 12 by the first arc plate 3.

[0045] Under the thrust of the cooling water, the elastic water bag 12 deforms towards the inside of the inner tube 1, so that the cooling water in the elastic water bag 12 can directly contact the high-temperature flue gas in the inner tube 1, thereby enhancing the heat absorption effect of the cooling water on the flue gas.

[0046] At the same time, during the process of the elastic water bag 12 deforming towards the inside of the inner tube 1, its wall thickness will gradually become thinner, which is beneficial to the heat transfer of the flue gas to the cooling water.

[0047] Refer to Figure 2 and Figure 3, a wavy inner frame is provided inside the inner tube 1 and surrounds the tubular heat conduction tube 18. During the deformation process of the elastic water bag 12 into the inner tube 1, the elastic water bag 12 tends to deform towards the heat conduction tube 18, which is beneficial to increasing the contact area between the elastic water bag 12 and the high-temperature flue gas, thereby improving the recovery effect of the cooling water on the heat of the flue gas.

[0048] Refer to Figure 1 , on the side of the first arc plate 3 facing away from the axis of the inner tube 1, a second arc plate 13 is provided, and a bearing rod 14 is fixedly connected between the first arc plate 3 and the second arc plate 13.

[0049] The driving assembly 15 includes guide blocks 151 integrally formed on both arc-shaped sides of the first arc plate 3. A sliding groove 201 for the guide blocks 151 to slide is opened on the side wall of the partition strip 2. A compression spring 152 is propped between one end of the sliding groove 201 relative to the axis of the inner tube 1 and the guide block 151.

[0050] The driving assembly 15 further includes a bearing ring 153 that is at the same level as and closely attached to the second arc plate 13. The distance between the inner side wall of the bearing ring 153 and the axis of the inner tube 1 is equal to the distance between the outer side wall of the partition strip 2 and the axis of the inner tube 1.

[0051] A notch 1541 is opened on the bearing ring 153, and a bearing plate 154 is fixedly connected directly below the notch 1541. A first motor 155 electrically connected to the control system is bolted to the bearing plate 154. A runner 156 is fixedly sleeved on the output shaft of the first motor 155. The runner 156 is eccentrically arranged with respect to the output shaft of the first motor 155 and the runner 156 abuts against the outer arc surface of the second arc plate 13.

[0052] Refer to Figure 1 , Figure 2 and Figure 3 , when the notch 1541 on the bearing ring 153 is directly opposite the outer arc surface of a first arc plate 3, the output shaft of the first motor 155 drives the runner 156 to rotate. Since the runner 156 is eccentrically arranged, during the rotation of the runner 156, the first arc plate 3 can be pushed towards the direction close to the axis of the inner tube 1.

[0053] When the first arc plate 3 is directly opposite the notch 1541 again, the thrust of the compression spring 152 on the guide block 151 can push the first arc plate 3 towards the direction away from the axis of the inner tube 1. Therefore, the cooling water in the elastic water bag 12 after sufficient heat absorption flows back into the heat absorption cavity 4 under the action of the deformation force.

[0054] Refer to Figure 1 , Figure 2 and Figure 3, the turnover assembly 16 includes a second motor 161 electrically connected to the control system, a sprocket 162 fixedly sleeved on the output shaft of the second motor 161, a chain link 163 rotatably sleeved outside several partition bars 2, and a chain 164 sleeved between the chain link 163 and the sprocket 162. A support rod 165 is fixedly connected between the chain link 163 and the bearing ring 153. In the prior art, there is also a bracket (not shown in the figure) for supporting the second motor 161.

[0055] Referring to Figure 1 , Figure 2 and Figure 3 , the output shaft of the second motor 161 drives the chain link 163 to rotate through the sprocket 162 and the chain 164, and the chain link 163 drives the bearing ring 153 to rotate through the support rod 165, thereby realizing the turnover of the drive assembly 15.

[0056] Referring to Figure 1 , Figure 2 and Figure 3 , when the distance between the first arc plate 3 and the axis of the inner tube 1 is the smallest, the communication between the drain valve 8 and the heat absorption chamber 4 is located on the side of the first arc plate 3 facing the inner tube 1. When the condenser is about to stop working, the control system opens all the drain valves 8 and the inlet valves 11, so that all the drain valves 8 can drain all the cooling water in the corresponding heat absorption chamber 4.

[0057] The implementation principle of an energy-saving and highly efficient flue gas condenser in an embodiment of the present application is as follows:

[0058] The control system starts the second motor 161, and the output shaft of the second motor 161 drives the chain link 163 to rotate through the sprocket 162 and the chain 164, and the chain link 163 drives the drive assembly 15 to rotate through the support rod 165.

[0059] The cooling water flows into the water inlet cylinder 5 through the water inlet pipe 7. The control system sequentially opens the drain valves 8 circumferentially, and then discharges the original cooling water with sufficient heat absorption in the heat absorption chamber 4. The floating plate 10 gradually descends until it reaches the lowest position. Then, the control system closes the drain valves 8 and opens the corresponding inlet valves 11. The cooling water above the floating plate 10 flows through the inlet valves 11 to the lower side of the floating plate 10. At this time, the floating plate 10 floats upward under the action of buoyancy until it is completely in the receiving groove, and at this time, the control system closes the inlet valves 11.

[0060] The control system starts the first motor 155, and the output shaft of the first motor 155 drives the runner 156 to rotate. During the rotation of the runner 156, the second arc plate 13 and the bearing rod 14 can push the first arc plate 3 to move towards the axis of the inner tube 1. The first arc plate 3 pushes a part of the cooling water in the heat absorption cavity 4 into the elastic water bag 12, and the elastic water bag 12 deforms into the inner tube 1. When the driving component 15 rotates one circle, during the process of the output shaft of the first motor 155 driving the runner 156 to rotate, the compression spring 152 can push the first arc plate 3 away from the inner tube 1, and then the cooling water in the heat absorption cavity 4 can be discharged.

[0061] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
