Existing equipment will dissipate heat from the part where the liquid contacts the pipeline, but the contact area between the liquid and the pipeline wall is limited, resulting in limited heat exchange effect. Summary of the invention

[0007] The cooling mechanism includes:

[0008] A fixing frame, the fixing frame is fixedly connected to the inside of the access pipe;

[0009] A rotating rod, the rotating rod being movably connected inside the fixing frame;

[0010] The baffle plate is fixedly connected to the bottom of the rotating rod and is located inside the connecting tube.

[0011] The circular ring orifice plate is fixedly connected to the top of the baffle plate.

[0012] Preferably, a first spiral push plate is fixedly connected to the bottom of the baffle plate inside the connecting tube, and an outer spiral air push plate is fixedly connected to the outer wall of the connecting tube. The outer spiral air push plate is made of a material with good thermal conductivity and serves to increase the contact area with the external airflow, thereby increasing the heat exchange area.

[0013] Preferably, the outer wall of the connecting pipe is movably connected to a fixed shell, the fixed shell is rotatably connected to the connecting pipe via a bearing, the top of the fixed shell is fixedly connected to a dustproof net, and the outer wall of the fixed shell is fixedly connected to a mounting frame.

[0014] Preferably, the inner wall of the connecting tube is located on the top of the first spiral push plate and is fixedly connected with several inner wall inclined plates, and the spiral direction of each inner wall inclined plate is opposite to that of the first spiral push plate. Since the spiral direction of the inner wall inclined plate is opposite to that of the first spiral push plate, the inner wall inclined plate will play a certain role in pushing the falling liquid upward when it is rotated by the connecting tube.

[0015] Preferably, the circulation mechanism includes a second spiral push plate, which is fixedly connected to the outer wall of the rotating rod, and the bottom of the baffle plate is fixedly connected to a rotating cylinder, and an inner spiral air push plate is fixedly connected to the inside of the rotating cylinder, and the spiral direction of the inner spiral air push plate is opposite to that of the second spiral push plate. An exhaust groove is provided on the outer wall of the rotating cylinder, and the rotation of the rotating cylinder will cause the inner spiral air push plate inside it to play a role of pushing air upwards, and allow the air to be discharged outward from the exhaust groove.

[0016] Preferably, an exhaust plate is fixedly connected to the outer wall of the rotating cylinder, and the position of the exhaust plate corresponds to the position of the exhaust notch.

[0017] Preferably, the bottom of the baffle plate is located inside the rotating cylinder and is fixedly connected to an inner suction pipe, the inner suction pipe is fixedly connected to an inner suction spiral plate, and an opening is provided on the outer wall of the inner suction pipe located at the top of the inner suction spiral plate.

[0019] The present invention provides a chemical high-efficiency heat exchanger for chemical production, which has the following beneficial effects:

[0020] 1. The chemical high-efficiency heat exchanger used in chemical production disperses the liquid from the holes on the circular orifice plate to the surroundings under the action of pressure, hits the inner wall of the connecting pipe, and flows downward along the inner wall of the connecting pipe, which increases the surface area of ​​the liquid in contact with the heat exchange surface. At the same time, the outer spiral air pusher plate pushes the external air flow, thereby promoting the air flow on the surface of the connecting pipe, so that the liquid descending along the surface of the connecting pipe can better transfer heat to the external air, thereby improving the efficiency of heat exchange.

[0021] 2. The chemical high-efficiency heat exchanger used in chemical production is pushed by the liquid through the first spiral push plate, so that the inner wall inclined plate on the inner wall of the connecting pipe rotates together with the connecting pipe. Since the spiral direction of the inner wall inclined plate is opposite to that of the first spiral push plate, the inner wall inclined plate will push the falling liquid upward when being rotated by the connecting pipe, thereby extending the speed of the liquid on the inner wall of the connecting pipe flowing downward and increasing the contact time between the liquid on the inner wall of the connecting pipe and the heat exchange surface, thereby enhancing the heat exchange effect.

[0022] 3. The chemical high-efficiency heat exchanger used for chemical production drives the second spiral push plate through the liquid to rotate the rotating rod, so that the inner spiral push plate can play the role of pushing the air upward, so that the air is discharged outward from the exhaust slot, promoting the air circulation inside the connecting pipe, and at the same time, it is discharged through the inner suction pipe through the opening on the inner suction pipe, and under the action of the airflow generated by the exhaust plate, it flows to the liquid on the inner wall of the connecting pipe, so that the water temperature inside the connecting pipe can become more evenly distributed, which can promote heat exchange and improve the efficiency of heat exchange.

[0023] 4. In the chemical high-efficiency heat exchanger used in chemical production, the rotation of the exhaust plate will push the air discharged from the exhaust slot outward through the action of centrifugal force, so that the airflow blows toward the inner wall of the connecting pipe, and the liquid attached to the inner wall of the connecting pipe will become more evenly attached to the inner wall of the connecting pipe under the action of blowing, which can further increase the area of ​​the liquid and the inner wall of the connecting pipe to enhance the efficiency of heat exchange.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0036] Example 1: Please refer to Figure 1-8 The present invention provides a technical solution: a chemical high-efficiency heat exchanger for chemical production, comprising a connecting pipe 1, the connecting pipe 1 is made of a material with good thermal conductivity, the top of the connecting pipe 1 is movably connected with an access pipe 2, which is rotatably connected to the connecting pipe 1 through a bearing, the bottom of the connecting pipe 1 is movably connected with a discharge pipe 3, the discharge pipe 3 is rotatably connected to the connecting pipe 1 through a bearing, the inside of the access pipe 2 is fixedly connected with a cooling mechanism 4, and the bottom of the cooling mechanism 4 is fixedly connected with a circulation mechanism 5;

[0037] The cooling mechanism 4 comprises:

[0038] A fixing frame 401, the fixing frame 401 is fixedly connected to the inside of the access pipe 2;

[0039] A rotating rod 402, the rotating rod 402 is movably connected to the interior of the fixing frame 401;

[0040] The baffle plate 403 is fixedly connected to the bottom of the rotating rod 402, and the baffle plate 403 is located inside the connecting pipe 1

[0041] The circular orifice plate 404 is fixedly connected to the top of the blocking plate 403 .

[0042] Connect the top of the access pipe 2 to the corresponding chemical pipeline, connect the bottom of the discharge pipe 3 to the corresponding chemical pipeline, and make the access pipe 2 at the top and the discharge pipe 3 at the bottom, so that the chemical liquid that needs to be cooled is sent from the access pipe 2 to the discharge pipe 3. The liquid enters the inside of the connecting pipe 1 through the access pipe 2, and then enters the inside of the discharge pipe 3 from the inside of the connecting pipe 1. When the liquid is discharged from the access pipe 2 to the inside of the connecting pipe 1, the liquid will be blocked by the blocking plate 403, and the liquid will be dispersed to the surroundings from the holes on the annular orifice plate 404 under the action of pressure, hit the inner wall of the connecting pipe 1, and flow downward along the inner wall of the connecting pipe 1, which will increase the surface area of ​​the liquid in contact with the heat exchange surface, so that the connecting pipe 1 can better contact with the heat exchange area, flow into the access pipe 2 through the bottom of the connecting pipe 1 and then be discharged.

[0043] A first spiral push plate 410 is fixedly connected to the bottom of the blocking plate 403 inside the connecting tube 1, and an outer spiral air push plate 405 is fixedly connected to the outer wall of the connecting tube 1. The outer spiral air push plate 405 is made of a material with good thermal conductivity and serves to increase the contact area with the external airflow, thereby increasing the heat exchange area.

[0044] When the liquid inside the connecting pipe 1 flows into the discharge pipe 3 through the bottom of the connecting pipe 1, the liquid will flow through the first spiral push plate 410, which will generate thrust on the first spiral push plate 410 to rotate the first spiral push plate 410, and the first spiral push plate 410 will also rotate with the connecting pipe 1. When the connecting pipe 1 is rotated together, it will push the outer spiral push plate 405 to rotate. The outer spiral push plate 405 is located outside and will promote the flow of air outside, thereby promoting the flow of air on the surface of the connecting pipe 1, so that the liquid descending along the surface of the connecting pipe 1 can better transfer heat to the outside air.

[0045] The outer wall of the connecting pipe 1 is movably connected with a fixed shell 406, and the fixed shell 406 is rotatably connected to the connecting pipe 1 through a bearing. The top of the fixed shell 406 is fixedly connected with a dustproof net 408, and the outer wall of the fixed shell 406 is fixedly connected with a mounting frame 407.

[0046] The fixed shell 406 is fixed on the fixing device through the mounting frame 407, and the rotation of the outer spiral air pushing plate 405 allows the air to flow downward through the dustproof net 408. The dustproof net 408 can block the dust in the air and prevent the dust from hindering the heat transfer between the connecting pipe 1 and the surface of the outer spiral air pushing plate 405.

[0047] The inner wall of the connecting pipe 1 is located on the top of the first spiral push plate 410 and is fixedly connected with a plurality of inner wall inclined plates 409 , and the spiral direction of each inner wall inclined plate 409 is opposite to that of the first spiral push plate 410 .

[0048] When the first spiral push plate 410 is driven by the liquid to rotate the connecting pipe 1, the inner wall inclined plate 409 on the inner wall of the connecting pipe 1 will rotate together with the connecting pipe 1. Since the spiral direction of the inner wall inclined plate 409 is opposite to that of the first spiral push plate 410, the inner wall inclined plate 409 will play a certain role in pushing the falling liquid upward when being rotated by the connecting pipe 1, thereby extending the speed of the liquid on the inner wall of the connecting pipe 1 flowing downward and increasing the contact time between the liquid on the inner wall of the connecting pipe 1 and the heat exchange surface.

[0049] Example 2: Please refer to Figure 1-9 Based on the first embodiment, the present invention provides a technical solution:

[0050] The circulation mechanism 5 includes a second spiral push plate 501, which is fixedly connected to the outer wall of the rotating rod 402. The bottom of the blocking plate 403 is fixedly connected to a rotating cylinder 502. The inside of the rotating cylinder 502 is fixedly connected to an inner spiral air push plate 503, and the spiral direction of the inner spiral air push plate 503 is opposite to that of the second spiral push plate 501. An exhaust slot 504 is opened on the outer wall of the rotating cylinder 502.

[0051] When liquid enters the connecting pipe 1 through the access pipe 2, it pushes the second spiral push plate 501 to rotate the rotating rod 402, and the rotating cylinder 502 at the bottom of the blocking plate 403 rotates through the rotation of the rotating rod 402. The rotation of the rotating cylinder 502 allows the inner spiral air push plate 503 inside it to push the air upward, and let the air be discharged from the exhaust slot 504, thereby promoting air circulation inside the connecting pipe 1.

[0052] An exhaust plate 505 is fixedly connected to the outer wall of the rotating cylinder 502 , and the position of the exhaust plate 505 corresponds to the position of the exhaust notch 504 .

[0053] The exhaust plate 505 will rotate together with the rotating cylinder 502. The rotation of the exhaust plate 505 will push the air exhausted from the exhaust slot 504 outward through the action of centrifugal force, and will allow the air to blow onto the liquid flowing downward from the inner wall of the connecting tube 1. Since the liquid inside the connecting tube 1 flows downward along the inner wall of the connecting tube 1 in a dispersed manner, the airflow will be able to better act on the connecting tube 1. At the same time, the airflow will blow onto the inner wall of the connecting tube 1, and the liquid attached to the inner wall of the connecting tube 1 will become more evenly attached to the inner wall of the connecting tube 1 under the action of blowing.

[0054] The bottom of the blocking plate 403 is located inside the rotating cylinder 502 and is fixedly connected to an inner suction pipe 506 , an inner suction spiral plate 507 is fixedly connected inside the inner suction pipe 506 , and an opening is provided on the outer wall of the inner suction pipe 506 located at the top of the inner suction spiral plate 507 .

[0055] The spiral direction of the inner suction spiral plate 507 is opposite to that of the second spiral push plate 501 , and the bottom of the inner suction pipe 506 corresponds to the position.

[0056] When the liquid flows to the bottom of the access pipe 2, the inner suction pipe 506 will be rotated together with the crushing rotating cylinder 502 by the baffle plate 403. When the inner suction pipe 506 rotates, the internal inner suction spiral plate 507 will pump the water flowing to the bottom of the access pipe 2 upward. Since the inner suction spiral plate 507 continues to pump the liquid, the liquid pressure inside the inner suction pipe 506 will increase, and then it will be discharged through the opening on the inner suction pipe 506, and on the liquid flowing on the inner wall of the connecting pipe 1 under the action of the airflow generated by the exhaust plate 505. The temperature of the liquid at the bottom is lower. According to the basic principle of heat conduction, its heat transfer rate with the outside world is lower. Extracting liquid through the inner suction pipe 506 can make the water temperature inside the connecting pipe 1 become more evenly distributed.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
