Description

Technical Field

[0001] The invention relates to the technical field of steam condensation, and in particular to a steam condensation recovery and utilization device. Background Art

[0002] The widespread use of steam in industrial production has made the effective treatment of steam condensate an important part of improving energy efficiency and saving costs. During the heating process of steam heating equipment, steam will condense into condensate after heat exchange. If this condensate is not discharged in time or effectively recycled, it will have an adverse effect on the normal operation of the equipment and even lead to energy waste. Most of the existing steam condensate recovery devices adopt a parallel drainage structure, connecting multiple heat exchangers to a steam condensate recovery device, and multiple drainage passages work in parallel. In the existing steam condensate recovery device, although the multiple drainage passages are in parallel, there is still physical connectivity in the structure. If the temperature of the condensate is different after heat exchange in multiple heat exchangers, this physical connectivity will cause the high-temperature condensate to hinder the smooth discharge of the low-temperature condensate during the discharge process, resulting in low discharge efficiency of condensate at different temperatures, which in turn affects the recovery efficiency of condensate. Summary of the invention

[0003] The invention provides a steam condensation recovery device to solve the problem of low condensate recovery efficiency of existing steam condensation recovery devices.

[0004] A steam condensation recovery and utilization device of the present invention adopts the following technical solution:

[0005] A steam condensation recovery and utilization device comprises a collecting tube, a sealing disk and a control unit.

[0008] Furthermore, the adjustment control unit includes an adjustment shaft and an adjustment rod. The adjustment shaft is coaxially rotatably connected to the sealing disk. The adjustment rod is arranged along the radial direction of the adjustment shaft. One end of the adjustment rod is fixedly connected to the adjustment shaft, and the other end of the adjustment rod is arranged as an extrusion slope. When the adjustment shaft rotates, the extrusion slope of the adjustment rod can squeeze the limit block out of the limit groove.

[0009] Furthermore, the adjustment control unit also includes an adjustment torsion spring, which is arranged between the adjustment shaft and the sealing disk. When the adjustment shaft rotates relative to the sealing disk, the adjustment torsion spring can accumulate force. In the process of condensed water discharged from the heat exchanger entering the collection tube, the adjustment shaft gradually rotates.

[0010] Furthermore, the adjustment control unit also includes a water collecting bucket, a guide plate and a transmission member. The guide plate is fixedly arranged in the installation cavity. A guide tube is arranged in the middle of the guide plate. The guide plate can guide the condensed water discharged from the through hole to the inside of the guide tube; the water collecting bucket is arranged inside the guide tube, and the water collecting bucket can slide up and down inside the guide tube. The transmission member is arranged between the water collecting bucket and the adjustment shaft. When the water collecting bucket moves relative to the adjustment shaft, the adjustment shaft rotates through the transmission of the transmission member.

[0011] Furthermore, the transmission member includes a transmission sleeve; the transmission sleeve is coaxially sleeved inside the guide tube, and the transmission sleeve and the water collecting bucket are connected by a connecting rod. When the transmission sleeve slides inside the guide tube, the transmission sleeve is guided to rotate inside at the same time, and when the transmission sleeve rotates, it can drive the regulating shaft to rotate synchronously.

[0012] Furthermore, a spiral protrusion is provided on the outer wall of the transmission sleeve, a spiral groove is provided on the inner wall of the guide tube, and the spiral protrusion is slidably arranged in the spiral groove; when the weight of the water collecting bucket increases, the transmission sleeve slides and rotates inside the guide tube.

[0013] Furthermore, a ratchet groove is provided on the inner side wall of the transmission sleeve, and an elastic claw is provided on the regulating shaft.

When the condensed water inside the water collecting bucket reaches a first preset weight, the water collecting bucket can be flipped over so that the condensed water inside the water collecting bucket is separated from the water collecting bucket; a reset spring is provided between the transmission sleeve and the guide tube, and the reset spring is used to drive the transmission sleeve to reset.

[0015] Furthermore, a protective sleeve is provided on the guide tube, which can prevent the condensed water inside the water collecting bucket from turning over when the condensed water does not reach a first preset weight; the protective sleeve can slide on the guide tube, and the first preset weight of the condensed water in the water collecting bucket can be adjusted.

[0016] The beneficial effects of the present invention are as follows: a steam condensation recovery and utilization device of the present invention comprises a collecting tube, a sealing disk and an adjusting control unit. When multiple heat exchangers are connected to the collecting tube at the same time, each connecting pipe is connected to a heat exchanger. Under the action of the sealing disk, condensed water in only one heat exchanger among the multiple heat exchangers can enter the interior of the collecting tube. When the weight of condensed water discharged from any heat exchanger entering the interior of the collecting tube reaches a first preset weight, the adjusting control unit can adjust the sealing disk to rotate a preset angle in the installation cavity, and change the heat exchanger to discharge condensed water into the collecting tube. By setting the sealing disk and the adjusting control unit, it is ensured that multiple heat exchangers can alternately transport condensed water to the interior of the collecting tube. When the temperatures of condensed water are different after heat exchange in multiple heat exchangers, the condensed water in different heat exchangers does not interfere with each other. Moreover, the weight of condensed water discharged from each heat exchanger to the interior of the collecting tube is the first preset weight. Then, the temperature of condensed water after heat exchange in different heat exchangers will not interfere with the weight of condensed water discharged to the interior of the collecting tube, thereby ensuring that the recovered condensed water can run smoothly, thereby improving the recovery efficiency of the condensed water.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0029] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0030] like Figures 1 to 8 As shown, a steam condensation recovery and utilization device provided in an embodiment of the present invention includes a collecting tube 110, a sealing disk 140 and a control unit.

[0031] The collecting tube 110 is cylindrical, the axis of the collecting tube 110 is vertically arranged, the inside of the collecting tube 110 is hollow, the hollow chamber inside the collecting tube 110 is the installation chamber 111, and the upper end of the collecting tube 110 is provided with a plurality of connecting pipes 120 connecting the external environment and the installation chamber 111, that is, the connecting pipe 120 passes through the upper end surface of the collecting tube 110. Each connecting pipe 120 can be connected with a heat exchanger 130, and the condensed water discharged by the heat exchanger 130 can enter the installation chamber 111 through the connecting pipe 120. The plurality of connecting pipes 120 are evenly arranged around the circumferential direction of the upper end surface of the collecting tube 110, wherein the number of the connecting pipes 120 is the same as the number of the heat exchangers 130. When the number of the heat exchangers 130 is four, four connecting pipes 120 are arranged, and the four connecting pipes 120 are evenly distributed around the circumferential direction of the collecting tube 110.

[0032] The blocking disk 140 is coaxially rotatably disposed in the installation cavity 111. The upper end surface of the blocking disk 140 is always in contact with the upper end surface of the inner wall of the collecting tube 110. The upper end surface of the blocking disk 140 can block multiple connecting tubes 120, and the blocking disk 140 can prevent condensed water from entering the installation cavity 111 through the connecting tubes 120. The blocking disk 140 is provided with a through hole 141 that penetrates the upper and lower end surfaces of the blocking disk 140. The through hole 141 on the blocking disk 140 can be connected to any one of the connecting tubes 120. The number of the through hole 141 is one. When the through hole 141 is connected to one connecting tube 120, the condensed water in the heat exchanger 130 connected to the connecting tube 120 can enter the installation cavity 111, and the condensed water in the heat exchangers 130 connected to the other connecting tubes 120 cannot enter the installation cavity 111, so as to prevent the condensed water in different heat exchangers 130 from interfering with each other.

[0033] The control unit is used to adjust the plugging disc 140 to rotate at a preset angle in the installation cavity 111 when the weight of the condensed water discharged from any heat exchanger 130 and entering the collection tube 110 reaches a first preset weight. When the plugging disc 140 rotates at a preset angle, the through hole 141 changes the connected connecting pipe 120, and the heat exchanger 130 is changed to discharge condensed water into the collection tube 110, thereby ensuring that different heat exchangers 130 can discharge condensed water into the collection tube 110. Further, the control unit can adjust the plugging disc 140 to rotate at a preset angle in the installation cavity 111. When the connecting pipe 120 is set to four, the plugging disc 140 rotates at a preset angle of ninety degrees in the installation cavity 111. When the connecting pipe 120 is set to two, the plugging disc 140 rotates at a preset angle of one hundred and eighty degrees in the installation cavity 111.

[0034] In a steam condensation recycling device of the present invention, when multiple heat exchangers 130 are connected to a collection tube 110 at the same time, each connecting pipe 120 is connected to a heat exchanger 130. Under the action of the blocking disk 140, condensed water in only one heat exchanger 130 among the multiple heat exchangers 130 can enter the interior of the collection tube 110. When the weight of condensed water discharged from any heat exchanger 130 entering the interior of the collection tube 110 reaches a first preset weight, the control unit can adjust the blocking disk 140 to rotate a preset angle in the installation cavity 111, thereby changing the heat exchanger 130 to discharge condensed water into the collection tube 110. Water, by setting a sealing plate 140 and a regulating control unit, it is ensured that multiple heat exchangers 130 can alternately transport condensed water to the inside of the collecting tube 110. When the temperatures of the condensed water are different after heat exchange in multiple heat exchangers 130, the condensed water in different heat exchangers 130 does not interfere with each other, and the weight of the condensed water discharged by each heat exchanger 130 to the inside of the collecting tube 110 is the first preset weight. Then, the temperature of the condensed water after heat exchange in different heat exchangers 130 will not interfere with the weight of the condensed water discharged to the inside of the collecting tube 110, thereby ensuring that the recovery of the condensed water can run smoothly, thereby improving the recovery efficiency of the condensed water.

[0035] In one embodiment, a plurality of stop blocks 150 are disposed on the inner side wall of the collection tube 110, each stop block 150 can slide along the radial direction of the collection tube 110, a first elastic member is disposed between each stop block 150 and the side wall of the collection tube 110, specifically, the first elastic member is a first spring 160, the axial direction of the first spring 160 is disposed in the radial direction of the collection tube 110, one end of the first spring 160 is fixedly connected to the inner side wall of the collection tube 110, and the other end of the first spring 160 is fixedly connected to the stop block 150. Each stop block 150 is disposed corresponding to a connecting tube 120, specifically, the number of the stop blocks 150 is the same as the number of the connecting tubes 120, and the plurality of stop blocks 150 are evenly distributed around the circumferential direction of the inner side wall of the collection tube 110. The blocking plate 140 is provided with a limiting groove, the number of which is one, and the limiting groove is provided on the peripheral side wall of the blocking plate 140. Each limiting block 150 can be inserted into the limiting groove. When the limiting block 150 is inserted into the limiting groove, the through hole 141 on the blocking plate 140 is connected with one connecting pipe 120, and the other connecting pipes 120 are blocked by the upper end surface of the blocking plate 140. When the weight of the condensed water discharged from any heat exchanger 130 entering the collecting tube 110 reaches a first preset weight, the control unit can drive the limiting block 150 to disengage from the limiting groove. At the same time, the blocking plate 140 can rotate a preset angle in the installation cavity 111. When the rotation angle of the blocking plate 140 reaches the preset angle, another limiting block 150 enters the limiting groove.

[0036] In one embodiment, the adjustment control unit includes an adjustment shaft 210 and an adjustment rod 220. The adjustment shaft 210 is coaxially connected to the blocking disk 140 for rotation. The adjustment rod 220 is arranged along the radial direction of the adjustment shaft 210. One end of the adjustment rod 220 is fixedly connected to the adjustment shaft 210. The other end of the adjustment rod 220 is arranged to be an extrusion slope. When the adjustment shaft 210 rotates, the extrusion slope of the adjustment rod 220 can squeeze the limit block 150 out of the limit groove. Specifically, when any limit block 150 is in the limit groove, the blocking disk 140 is in a relatively static state. At this time, the adjustment shaft 210 rotates relative to the blocking disk 140, and the adjustment rod 220 is coaxially connected to the blocking disk 140. The regulating rod 220 and the regulating shaft 210 are both arranged below the blocking disk 140. By adjusting the thickness of the limit block 150 in the vertical direction to be greater than the thickness of the blocking disk 140 in the vertical direction, it is ensured that the end of the regulating rod 220 away from the regulating shaft 210 can contact the limit block 150. Since the end of the regulating rod 220 away from the regulating shaft 210 is an extrusion slope, when the regulating rod 220 rotates relative to the blocking disk 140, the extrusion slope of the regulating rod 220 can contact the limit block 150. With the further rotation of the regulating rod 220, the extrusion slope on the regulating rod 220 squeezes the limit block 150 out of the limit groove.

[0037] In one of the embodiments, the adjustment control unit also includes an adjustment torsion spring 230, which is arranged between the adjustment shaft 210 and the blocking disk 140. Specifically, the axis of the adjustment torsion spring 230 is in the same direction as the axis of the adjustment shaft 210, one end of the adjustment torsion spring 230 is fixedly connected to the blocking disk 140, and the other end of the adjustment torsion spring 230 is fixedly connected to the adjustment shaft 210. When the adjustment shaft 210 rotates relative to the blocking disk 140, the adjustment torsion spring 230 can store force. In the initial state, the adjustment torsion spring 230 is in an uncharged state. In the process of condensed water discharged from the heat exchanger 130 entering the interior of the collecting tube 110, the adjustment shaft 210 gradually rotates. When the weight of the condensed water discharged from the heat exchanger 130 into the collecting tube 110 reaches a first preset weight, the adjustment shaft 210 rotates by a preset angle. When there are four heat exchangers 130, the preset rotation angle of the regulating shaft 210 is ninety degrees, the regulating torsion spring 230 accumulates force, and the rotation angle of the regulating rod 220 is also ninety degrees. When the regulating rod 220 rotates ninety degrees, the regulating rod 220 squeezes the limit block 150 out of the limit groove, and then the regulating torsion spring 230 releases force. The regulating torsion spring 230 can quickly drive the sealing disk 140 to rotate ninety degrees in the installation cavity 111, and the through hole 141 on the sealing disk 140 quickly changes the connected connecting pipe 120, thereby changing the heat exchanger 130 to discharge condensed water into the collecting tube 110. Under the action of the regulating torsion spring 230, the rotation time of the sealing disk 140 is shortened, and the time interval for changing the heat exchanger 130 to discharge condensed water is reduced, thereby improving the recovery efficiency of condensed water.

[0038] In one embodiment, the control unit further includes a water collecting bucket 310, a guide plate 320 and a transmission member. The guide plate 320 is fixedly arranged in the installation cavity 111. The guide plate 320 is in an upwardly expanded shape. The condensed water entering the installation cavity 111 can fall on the guide plate 320. According to the shape of the guide plate 320, the condensed water falling on the guide plate 320 can be concentrated in the middle of the guide plate 320. A guide pipe 330 is arranged in the middle of the guide plate 320. The guide pipe 330 is coaxially arranged with the guide plate 320. The guide pipe 330 penetrates the guide plate 320. The condensed water falling on the guide plate 320 can enter the inside of the guide pipe 330. The water collecting bucket 310 is arranged inside the guide tube 330, and the water collecting bucket 310 can slide up and down inside the guide tube 330. In the initial state, there is no condensed water inside the water collecting bucket 310, and the water collecting bucket 310 and the guide tube 330 are in a relatively static state. As the condensed water enters the water collecting bucket 310, the overall weight of the water collecting bucket 310 increases, and the water collecting bucket 310 moves relative to the guide tube 330 under the action of its own gravity. The transmission member is arranged between the water collecting bucket 310 and the regulating shaft 210. When the water collecting bucket 310 moves relative to the regulating shaft 210, the regulating shaft 210 rotates through the transmission of the transmission member. When the weight of the condensed water discharged from the heat exchanger 130 to the water collecting bucket 310 reaches the first preset weight, the distance moved by the water collecting bucket 310 relative to the regulating shaft 210 is constant, and the angle of rotation of the regulating shaft 210 is constant through the transmission of the transmission member, thereby ensuring that the weight of the condensed water discharged from each heat exchanger 130 to the water collecting bucket 310 is the first preset weight.

[0039] In one of the embodiments, the transmission member includes a transmission sleeve 340, which is coaxially sleeved inside the guide tube 330. The transmission sleeve 340 and the water collecting bucket 310 are connected by a connecting rod 370. The connecting rod 370 is vertically arranged, the upper end of the connecting rod 370 is connected to the transmission sleeve 340, and the lower end of the connecting rod 370 is connected to the water collecting bucket 310. When there is no condensed water inside the water collecting bucket 310, the water collecting bucket 310 is in a relatively static state inside the guide tube 330. When the condensed water inside the water collecting bucket 310 gradually increases, the weight of the water collecting bucket 310 increases, and the water collecting bucket 310 moves relative to the guide tube 330. The movement of the water collecting bucket 310 drives the transmission sleeve 340 to move at the same time through the connecting rod 370 When the transmission sleeve 340 slides inside the guide tube 330, the transmission sleeve 340 rotates inside the guide tube 330 at the same time. Specifically, the outer wall of the transmission sleeve 340 is provided with a spiral protrusion, and the inner wall of the guide tube 330 is provided with a spiral groove, and the spiral protrusion is slidably arranged in the spiral groove; when the weight of the water collecting bucket 310 increases, the transmission sleeve 340 slides and rotates inside the guide tube 330. While the transmission sleeve 340 rotates, the water collecting bucket 310 rotates synchronously in the guide tube 330. When the transmission sleeve 340 rotates, it drives the regulating shaft 210 to rotate synchronously. Furthermore, when the weight of the condensed water inside the water collecting bucket 310 reaches the first preset weight, the condensed water in the water collecting bucket 310 can be discharged from the water collecting bucket 310 in time.

[0040] In one of the embodiments, a ratchet groove 350 is provided on the inner wall of the transmission sleeve 340, and the ratchet grooves 350 are arranged circumferentially around the inner wall of the transmission sleeve 340. An elastic claw 360 is provided on the regulating shaft 210, and the elastic claw 360 can cooperate with the ratchet groove 350 to form a one-way transmission member. When the weight of the water collecting bucket 310 increases, the transmission sleeve 340 rotates and moves downward relative to the guide tube 330. At this time, the elastic claw 360 cannot move relative to the ratchet groove 350, and the rotation of the transmission sleeve 340 is transmitted to the regulating shaft 210 through the transmission of the elastic claw 360 and the ratchet groove 350, so that the regulating shaft 210 rotates. At this time, there is relative movement between the regulating shaft 210 and the transmission sleeve 340 in the axial direction. By setting the length of the ratchet groove 350 in the axial direction, it is ensured that the elastic claw 360 is always in the ratchet groove 350.

[0041] In one of the embodiments, a partition 311 is provided in the middle of the water collecting barrel 310 in the axial direction. Specifically, the water collecting barrel 310 is arranged to penetrate up and down, and a partition 311 is provided in the middle of the water collecting barrel 310. The partition 311 is fixedly connected to the inner wall of the water collecting barrel 310. When the water collecting barrel 310 is in a vertical state, the partition 311 can separate the inside of the water collecting barrel 310 into two relatively isolated chambers. One end of the connecting rod 370 is fixedly connected to the transmission sleeve 340, and the other end of the connecting rod 370 is rotatably connected to the partition 311 in the middle of the water collecting barrel 310. When the condensed water inside the water collecting barrel 310 reaches a first preset weight, the water collecting barrel 310 can be flipped over, so that the condensed water inside the water collecting barrel 310 is separated from the water collecting barrel 310. When the condensed water inside the water collecting barrel 310 is separated from the water collecting barrel 310, the weight of the water collecting barrel 310 is reduced. To ensure that the condensed water is transported to the inside of the water collecting barrel 310 after the heat exchanger 130 is replaced, and to ensure that the weight of each heat exchanger 130 discharging the condensed water into the water collecting barrel 310 is the first preset weight, the transmission sleeve 340 needs to be restored to its initial position at this time. However, the regulating shaft 210 does not need to rotate in the opposite direction at this time. The guide tube 330 is provided with a return spring 380 to drive the transmission sleeve 340 to reset. Specifically, the return spring 380 is coaxially arranged with the transmission sleeve 340. The upper end of the return spring 380 is fixedly connected to the guide tube 330. The lower end of the return spring 380 is fixedly connected to a connecting ring. The connecting ring is rotatably connected to the transmission sleeve 340 to prevent the return spring 380 from hindering the rotation of the transmission sleeve 340. When the return spring 380 drives the transmission sleeve 340 to reset, the transmission sleeve 340 moves up relative to the guide tube 330. With the cooperation of the spiral protrusion and the spiral groove, the transmission sleeve 340 rotates in the opposite direction. At the same time, under the action of the elastic claw 360 and the ratchet groove 350, the regulating shaft 210 is in a stationary state.

[0042] In one embodiment, a protective sleeve 410 is provided on the guide tube 330, and the protective sleeve 410 can prevent the water collecting bucket 310 from turning over when the condensed water inside the water collecting bucket 310 does not reach the first preset weight. Specifically, the protective sleeve 410 is coaxially arranged with the guide tube 330, and when the condensed water inside the water collecting bucket 310 reaches the first preset weight, the upper end of the water collecting bucket 310 is separated from the lower end of the protective sleeve 410, and the protective sleeve 410 no longer hinders the turning over of the water collecting bucket 310, wherein the reason for the turning over of the water collecting bucket 310 is that the center of gravity of the water collecting bucket 310 is offset. Furthermore, the protective sleeve 410 can slide on the guide tube 330, and the first preset weight of the condensed water in the water collecting bucket 310 can be adjusted. It is easy to understand that when the upper end of the water collecting bucket 310 is separated from the lower end of the protective sleeve 410, the protective sleeve 410 will not hinder the turning of the water collecting bucket 310. By sliding the protective sleeve 410 on the guide tube 330, the distance that the water collecting bucket 310 moves downward can be changed when the upper end of the water collecting bucket 310 is separated from the lower end of the protective sleeve 410. The reason why the water collecting bucket 310 moves downward is that the condensed water inside the water collecting bucket 310 gradually increases, thereby realizing the regulation of the first preset weight of the condensed water in the water collecting bucket 310. Furthermore, the first preset weight should also be adjusted in combination with the number of heat exchangers 130 to ensure that the force stored in the regulating torsion spring 230 when the regulating shaft 210 rotates is sufficient to drive the blocking disk 140 to rotate a preset angle.

[0043] In one of the embodiments, in order to facilitate the adjustment of the protective sleeve 410, the guide tube 330 is arranged to pass through the lower end surface of the collecting tube 110, the protective sleeve 410 is arranged outside the installation cavity 111, and the water collecting bucket 310 is arranged outside the installation cavity 111. The condensed water discharged from the water collecting bucket 310 can be directly transported to the external environment.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
