Description

Technical Field

[0001] The invention relates to the technical field of heat exchangers, and in particular to a multifunctional integrated heat exchange device. Background Art

[0002] A heat exchanger is an energy-saving device that transfers heat between two or more fluids at different temperatures. It transfers heat from a fluid with a higher temperature to a fluid with a lower temperature so that the fluid temperature reaches the specified index of the process to meet the needs of process conditions. It is also one of the main equipment for improving energy utilization. The heat exchanger industry involves nearly 30 industries such as HVAC, pressure vessels, reclaimed water treatment equipment, chemicals, and petroleum, forming an industrial chain with each other.

[0003] During the use of the heat exchanger, the heat exchanger is jacketed on the outer wall of the container, and the heating surface is limited by the container wall. At the same time, another immersed coil heat exchanger used in the project is to bend the metal tube into various shapes that are suitable for the container, but the heat transfer coefficient outside the tube is small. Since both heat exchangers conduct heat through contact with the tube wall, the simple tube wall heat transfer effect is low. This batch heat exchange requires multiple operations, low production efficiency, and requires more labor costs. In the process of filling materials, the heat exchange pot needs to be opened, which causes the temperature in the heat exchange pot to drop. When heat exchange is performed again, more energy consumption will be generated. Summary of the invention

[0004] The purpose of the present invention is to solve the problems in the prior art of low batch heat exchange production efficiency, requiring more labor costs and generating more energy consumption, and to propose a multifunctional integrated heat exchange equipment.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] The cooling liquefaction component includes a heat exchange conduit and a plurality of interconnected cooling towers. The heat exchange conduit is connected to a heat exchange exhaust pipe and passes through the plurality of cooling towers in sequence. The heat exchange conduit is provided with a plurality of liquid outlet pipes corresponding to the cooling towers.

[0010] Preferably, both ends of the heat exchange tube are provided with mounting grooves, a plurality of connection ports are provided in the mounting grooves, and the mounting ring is sealingly rotatably connected to the mounting grooves, so that the feed pipe, the discharge pipe and the heat exchange discharge pipe are connected to the interior of the heat exchange tube.

[0012] Preferably, a driving gear is fixedly mounted on the output end of the motor, and a gear ring meshing with the driving gear is fixedly disposed on the outer wall of the heat exchange cylinder.

[0013] Preferably, two adjacent cooling towers are connected by an S-shaped elbow, the input end of the S-shaped elbow is connected to the top of the cooling tower, the output end of the S-shaped elbow is connected to the bottom of the cooling tower, the top of the cooling tower close to the heat exchange tube is connected to the cooling water outlet pipe, and the bottom of the cooling tower away from the heat exchange tube is connected to the cooling water inlet pipe.

[0014] Preferably, a three-way pipe is provided on the cooling water outlet pipe, and one end of the three-way pipe is connected to the heat exchange boiler.

[0015] Preferably, the liquid outlet pipe has a U-shaped bending portion, and the height of the bending portion is greater than the diameter of the liquid outlet pipe.

[0016] Preferably, the output end of the liquid outlet pipe corresponding to the cooling tower near one end of the heat exchange tube is connected to a reflux pipe, the output end of the reflux pipe is connected to a mounting ring provided with a feed pipe and communicates with the interior of the heat exchange tube, and a water pump is provided on the reflux pipe.

[0017] Preferably, the heat exchange conduit enters from the top of the cooling tower and extends from the bottom, and the portion of the heat exchange conduit located in the cooling tower is spiral.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. By designing a rotatable heat exchange cylinder, the spiral blades are driven to rotate by the heat exchange cylinder, and the materials are transported during the heat exchange process, so that the hot gas completes the heat exchange during the transportation process, thereby realizing continuous heat exchange.

The heat exchange entering the cooling tower at the end has less hot gas content, mostly low-boiling point substances such as methanol, which can effectively cool down harmful substances such as methanol and reduce their content, ensure product safety and meet hygiene standards, and further improve quality.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described 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.

[0030] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0031] Reference Figure 1-4 , a multifunctional integrated heat exchange equipment, including a heat exchange generating component 1, a continuous heat exchange component 2 and a cooling liquefaction component 3.

[0032] The heat exchange generating component 1 has a heat exchange boiler 11 that can generate heat exchange. The heat exchange boiler 11 is a prior art and is used to generate high-temperature heat exchange, wherein the heating temperature can be precisely controlled by controlling the heat exchange pressure and flow rate. An outlet pipe 12 is horizontally arranged above the heat exchange boiler 11, and the output end of the heat exchange boiler 11 is connected to the outlet pipe 12. The heat exchange generated by the heat exchange boiler 11 is discharged through the outlet pipe 12 to provide heat to the continuous heat exchange component 2 for heat exchange. No open flame will be generated during the heat exchange heating process. Hot gas is flammable. In the process of brewing hot gas, the use of heat exchange heating reduces the risk of fire accidents and improves production safety.

[0033] The continuous heat exchange component 2 includes two mounting frames, on which mounting rings 21 are fixedly provided. The two mounting rings 21 are coaxially arranged, and a heat exchange tube 22 is rotatably arranged between the two mounting rings 21. A feed pipe 23 is connected to one of the mounting rings 21, and a discharge pipe 24 and a heat exchange discharge pipe 25 are connected to the other mounting ring 21. The end of the heat exchange tube 22 connected to the feed pipe 23 is the feed end, and the end of the heat exchange tube 22 connected to the discharge pipe 24 is the discharge end. Hot gas enters the heat exchange tube 22 through the feed pipe 23, and the heat exchange tube 22 rotates so that the hot gas is transported from the feed end to the discharge end. The hot gas is evaporated in the process of hot gas transportation, and the slag is discharged outward through the discharge pipe 24 when it reaches the discharge end.

[0034] Reference Figure 1-4 Both ends of the heat exchange tube 22 are provided with mounting grooves, and a plurality of connection ports are provided in the mounting grooves, the width of the connection ports is smaller than the width of the mounting grooves, and the mounting ring 21 is rotatably connected with the mounting grooves to make the feed pipe 23, the discharge pipe 24 and the heat exchange discharge pipe 25 communicate with the interior of the heat exchange tube 22, and the mounting ring 21 rotates in coordination with the mounting grooves to ensure the rotation stability of the heat exchange tube 22 and reduce the risk of axial deflection of the heat exchange tube 22, and because the connection ports are provided in the mounting grooves, during the rotation of the heat exchange tube 22, the feed pipe 23, the discharge pipe 24 and the heat exchange discharge pipe 25 can always remain connected with the interior of the heat exchange tube 22.

[0035] The outlet pipe 12 passes through the heat exchange tube 22 and is coaxially sealed and rotatably connected with the heat exchange tube 22. The outlet holes of the outlet pipe 12 are distributed in the internal area of ​​the heat exchange tube 22. The heat generated by the heat exchange boiler 11 is discharged into the heat exchange tube 22 through the outlet pipe 12, and the hot gas in the heat exchange tube 22 is heated to evaporate the hot gas to form heat exchange. The heat exchange enters the cooling and liquefaction component 3 through the heat exchange discharge pipe 25, and is cooled and liquefied to obtain hot gas liquid. A storage tank 28 is arranged above the heat exchange tube 22, and the storage tank 28 is connected to the feed pipe 23. The storage tank 28 is used to store hot gas. A valve is arranged between the storage tank 28 and the feed pipe 23. After the valve is opened, the hot gas flows into the heat exchange tube 22 through the feed pipe 23.

[0036] The continuous heat exchange component 2 also includes a motor 26 for driving the heat exchange tube 22 to rotate. A driving gear 261 is fixedly installed at the output end of the motor 26, and a gear ring 221 meshing with the driving gear 261 is fixedly provided on the outer wall of the heat exchange tube 22. After the motor 26 is started, the output shaft drives the driving gear 261 to rotate, and the driving gear 261 drives the gear ring 221 to rotate, so that the heat exchange tube 22 rotates continuously.

[0037] Reference Figure 3-4 The inner wall of the heat exchange tube 22 is provided with a spiral twisted sheet 27. When the heat exchange tube 22 rotates, the spiral twisted sheet 27 rotates together, so that the material in the heat exchange tube 22 is transported from the feed pipe 23 to the discharge pipe 24.

[0038] The spiral blades 27 are driven to rotate by the heat exchange cylinder 22, and the material is transported during the heat exchange process, so that the hot gas completes the heat exchange during the transportation process, thereby realizing continuous heat exchange. Compared with the batch heat exchange in the prior art, the heat exchange efficiency can be improved, and the production time and labor costs can be saved. In the continuous heat exchange process, there is no need to frequently switch on and off the equipment, which can reduce heat loss, reduce energy consumption, and improve production efficiency. Due to the stability and continuity of the heat exchange conditions, the stability of product quality can be guaranteed and the difference between batches can be reduced.

[0039] The axial position of the spiral blade 27 does not contact the outlet pipe 12, exposing the space for heat exchange circulation. The height of the hot gas in the heat exchange cylinder 22 does not exceed the thickness of the spiral blade 27, so that the spiral blade 27 can separate the hot gas intervals, preventing the hot gas that has not been completely evaporated from flowing directly to the discharge pipe 24 from the heat exchange circulation space, and a plurality of paddles 271 are arranged between the pitch gaps of the spiral blade 27. When the spiral blade 27 rotates, the paddle 271 will lift the hot gas to a certain height and then drop it, which has a stirring effect on the hot gas, thereby increasing the contact area between the hot gas and the heating heat exchange, thereby improving the heat exchange effect and making the heat exchange process more sufficient and uniform.

[0040] Reference Figure 1 , 2 The cooling liquefaction component 3 includes a heat exchange conduit 32 and a plurality of interconnected cooling towers 31. The heat exchange conduit 32 is connected to the heat exchange exhaust pipe 25 and passes through the plurality of cooling towers 31 in sequence. The cooling water enters through the cooling tower 31 on the side away from the heat exchange exhaust pipe 25, and gradually fills the plurality of cooling towers 31 in sequence. Since the cooling water flow direction in the cooling tower 31 is opposite to the heat exchange flow direction in the heat exchange conduit 32, the heat exchange effect between the hot gas heat exchange and the cooling water can be improved, and the hot gas heat exchange will be cooled every time it passes through a cooling tower 31. A portion of the cooling water is condensed and liquefied, and the temperature of the cooling tower 31 at the corresponding position is increased, and the temperature of the cooling tower 31 closer to one end of the heat exchange pipe 25 is higher, so that a stepped temperature difference is formed between each cooling tower 31, and as the cooling water flows, the cooling water in the low-temperature cooling tower 31 flows into the high-temperature cooling tower 31, and the flow rate of the cooling water is controlled, so that the temperature difference between each cooling tower 31 can be kept unchanged, and the effect of graded cooling is achieved, and a plurality of liquid outlet pipes 33 corresponding to the cooling tower 31 are arranged on the heat exchange pipe 32. The liquid outlet pipe 33 is arranged at a low position of the heat exchange pipe 32, and the hot gas liquid generated by the heat exchange of the condensed and liquefied hot gas enters the liquid outlet pipe 33 and is discharged outward through the liquid outlet pipe 33.

[0041] Reference Figure 6The liquid outlet pipe 33 has a U-shaped bending portion, and the height difference of the bending portion is greater than the diameter of the liquid outlet pipe 33. When the hot gas and liquid enter the liquid outlet pipe 33, the hot gas and liquid will accumulate at the bending portion until the liquid level exceeds the output end position of the liquid outlet pipe 33, and the hot gas and liquid will be discharged outward. The accumulation of hot gas and liquid at the bending portion will separate the connected hot gas heat exchange in the liquid outlet pipe 33 from the outside air, thereby preventing the hot gas heat exchange from leaking out.

[0042] In the process of batch heat exchange of hot gas, in order to ensure the quality of hot gas, it is necessary to remove the hot gas, that is, remove the head hot gas and the tail hot gas, and intercept the middle hot gas of the heat exchange. The reason is that the head hot gas contains more low-boiling point substances, including methanol, etc., which will be first exchanged out with the formation of heat exchange, affecting the taste of the hot gas and harmful to the human body. The tail hot gas is low-grade hot gas formed after the hot gas content is reduced, which does not meet the production quality. In the present invention, continuous heat exchange is carried out, and new hot gas is continuously added to the heat exchange cylinder 22. Therefore, new impurities such as methanol will be introduced. The traditional method of removing hot gas is obviously no longer applicable.

[0043] Reference Figure 1-2 Specifically, the traditional hot gas removal process is realized by cooling the liquefied component 3 in a graded cooling manner. It should be noted that at normal temperature and pressure, each cooling tower 31 is equipped with an independent thermometer to observe the real-time temperature. Warm water is introduced into the cooling tower 31a, and the water temperature needs to be lower than 64.5°C. As the heat exchange proceeds, the cooling water temperature in the cooling tower 31b and the cooling tower 31c rises. It is necessary to keep the water temperature in the cooling tower 31b and the cooling tower 31c greater than 64.5°C, and control the water temperature of the cooling tower 31d to 78.5°C±5°C. During the heat exchange process, the heat enters the cooling tower 31d along the heat exchange conduit 32.

[0044] Reference Figure 1-2 5. Two adjacent cooling towers 31 are connected by an S-shaped elbow 34. The input end of the S-shaped elbow 34 is connected to the top of the cooling tower 31, and the output end of the S-shaped elbow 34 is connected to the bottom of the cooling tower 31. The top of the cooling tower 31 close to the heat exchange tube 22 is connected to the cooling water outlet pipe 35, and the bottom of the cooling tower 31 far away from the heat exchange tube 22 is connected to the cooling water inlet pipe 36. The heat exchange conduit 32 enters from the top of the cooling tower 31 and extends from the bottom, so that the cooling water enters from the bottom and exits from the top, and the heat exchange enters from the top and exits from the bottom, which can improve the efficiency and purity of the heat exchange, promote more sufficient contact between the heat exchange and the coolant, increase the heat transfer effect, and help improve the yield and purity of the hot gas. The part of the heat exchange conduit 32 located in the cooling tower 31 is spiral, the purpose of which is to increase the heat exchange time and heat exchange contact area with the cooling water and maintain efficient heat exchange.

[0045] The output end of the liquid outlet pipe 33 corresponding to the cooling tower 31 near one end of the heat exchange tube 22 is connected to a return pipe 37. The output end of the return pipe 37 is connected to the mounting ring 21 provided with the feed pipe 23 and communicates with the interior of the heat exchange tube 22. A water pump is provided on the return pipe 37. The low-degree hot gas liquid collected by the liquid outlet pipe 33 below the cooling tower 31d is pumped into the heat exchange tube 22 through the return pipe 37 for re-evaporation. This part of the low-degree hot gas liquid has fewer impurities, and re-evaporation is beneficial to reducing losses.

[0046] A tee is provided on the cooling water outlet pipe 35, one end of which is connected to the heat exchange boiler 11. When water inside the heat exchange boiler 11 needs to be added, the cooling water is guided into the heat exchange boiler 11 through the tee for replenishment. Since the cooling water in the cooling tower 31 has a higher temperature after heat exchange, it can be used in the heat exchange boiler 11 to reduce the energy consumption of the heat exchange boiler 11 and reduce heat energy loss.

[0047] 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.
