Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of chemical equipment, especially to a device integrating condensation and heat exchange functions. BACKGROUND

[0002] In the field of industrial production and energy utilization, condensation and heat exchange are two extremely critical links. In many industrial processes, such as chemical industry, pharmaceutical industry, petroleum refining, etc., a large amount of high-temperature gas is often generated, which needs to be condensed to recover useful substances or meet subsequent process requirements. At the same time, the effective use of the heat contained in these high-temperature gases not only improves energy utilization efficiency and reduces production costs, but also meets the development trend of energy saving and emission reduction in today's society.

[0003] In the prior art, common condensation and heat exchange equipment often operates independently. Traditional condensation equipment mainly cools gaseous substances into liquid state through cooling medium, but it only focuses on completing the condensation process and ignores the effective use of heat released during condensation. For example, the common shell-and-tube condenser cools the gaseous substances in the tube by passing the cooling medium in the shell, but the heat taken away by the cooling medium is usually directly discharged into the environment, causing waste of energy.

[0004] In terms of heat exchange equipment, although the traditional heat exchanger can realize heat transfer from one medium to another, it is usually not combined with the condensation process. For example, the plate heat exchanger only simply realizes heat exchange between cold and hot fluids, and for those processes that need to be condensed first and then heat exchanged, additional condensation equipment needs to be configured, which not only increases the equipment investment cost, but also occupies a large space.

[0005] Moreover, the existing condensation and heat exchange equipment has obvious deficiencies in temperature control and adaptation to different working conditions. When the gas flow, temperature or pressure in the process changes, these devices are difficult to adjust quickly and accurately, thereby affecting the condensation and heat exchange effect, reducing production efficiency and product quality. For example, in some chemical production, due to the fluctuation of reaction conditions, the gas temperature and flow entering the condensation equipment are unstable, and the traditional equipment cannot timely adapt to these changes, resulting in poor condensation effect, which further affects the subsequent heat exchange and production process.

[0006] In addition, the existing condensation and heat exchange equipment is often not compact in structure design, and the connecting pipeline is complex, which not only increases the installation and maintenance difficulty of the equipment, but also is prone to leakage and other problems, reducing the reliability and operation stability of the equipment.

[0007] Therefore, a device integrating condensation and heat exchange functions is needed to solve the above problems. UTILITY MODEL CONTENTS

[0008] The utility model discloses a kind of integrated condensing and heat exchange function equipment to solve the shortcoming existing in prior art.

[0009] To achieve the above object, the utility model adopts the following technical scheme: a kind of integrated condensing and heat exchange function equipment, including integrated tower, chemical equipment and condensing tank, the bottom end of the chemical equipment is connected with air inlet pipeline, the bottom end of the air inlet pipeline is connected with air inlet pump, the air inlet pump is installed at the top of integrated tower, condensing tank is placed at the side of the integrated tower, the top end of the side of the condensing tank is connected with liquid inlet pipe, the bottom end of the side of the condensing tank is connected with liquid outlet pipe, serpentine pipe group is installed at the top in the integrated tower.

[0010] Preferably, the top end of the serpentine pipe group is connected with the liquid inlet pipe, and the bottom end of the serpentine pipe group is connected with the liquid outlet pipe.

[0011] Preferably, a sieve plate is installed near the bottom of the serpentine pipe group in the integrated tower, and sieve holes are formed in the top of the sieve plate.

[0012] Preferably, a mounting plate is clamped near the bottom of the sieve plate in the integrated tower, and there are three mounting plates in the integrated tower.

[0013] Preferably, an external connecting pipe is penetrated between adjacent mounting plates in the integrated tower, and a water accumulation tray is installed at the bottom of the integrated tower.

[0014] Preferably, a slot is formed in the middle of the top end of the mounting plate, a temperature detector is installed on one side of the top of the mounting plate, a drive motor is installed on one side in the mounting plate, a stretching plate is slidably connected inside the slot, and the stretching plate is foldable.

[0015] Preferably, a threaded shaft is drivingly connected to one end of the drive motor, a moving ring is threadedly connected to the outside of the threaded shaft, a limiting vertical shaft is threadedly connected to the top end of the moving ring, and the end of the limiting vertical shaft is slidably connected with the slot.

[0016] Advantages

[0017] The utility model discloses, the whole equipment effectively solved the energy waste problem caused by traditional condensation and heat exchange equipment separate operation. Through the collaborative operation of condensing tank, serpentine pipe group and external pipeline, the recycling of condensate and the multistage recovery of heat are realized. When high-temperature gas is condensed in the serpentine pipe group, the released heat can be transmitted to external equipment with different temperature requirements through the external pipeline, completing the heat exchange process of high-temperature, medium-temperature and low-temperature three stages, avoiding direct discharge of heat to the environment, and greatly improving the energy utilization efficiency. At the same time, the integrated design of the equipment reduces the cost of purchasing condensation and heat exchange equipment separately, reduces the operation energy consumption, and in the long run, can significantly reduce the production cost, in line with the development direction of industrial production energy saving and consumption reduction.

[0018] In the utility model, the high-temperature water after condensation first falls on the first layer mounting plate, and the refrigerating fin of the semiconductor refrigerating fin on the mounting plate starts to work to accelerate the cooling of the water, and at the same time, the heat of the high-temperature water is transmitted to external equipment needing high-temperature heat through the external pipeline, realizing high-temperature heat exchange. A high-precision digital temperature detector is selected on one side of the top of the mounting plate to monitor the temperature of the water in real time. When the temperature of the water is detected from high temperature to medium temperature, the temperature detector will quickly transmit the temperature change signal to the driving motor on one side of the mounting plate. After the driving motor starts, the output shaft drives the screw shaft connected with it to start rotating. Since the screw shaft and the moving ring are connected by threads, with the rotation of the screw shaft, the moving ring will move linearly along the screw shaft. The top of the moving ring is connected with the limiting vertical shaft by threads, and the end of the limiting vertical shaft is embedded in the groove in the middle of the top of the mounting plate and is connected with the groove by sliding, ensuring the stability of the moving ring during movement, so that it can only move linearly along the screw shaft. With the movement of the moving ring, the foldable stretching plate connected with it will be pulled and gradually unfolded. BRIEF DESCRIPTION OF DRAWINGS

[0035] Mounting plate 9 is clamped at the bottom close to serpentine pipe group 7 in integrated tower 1, there are three groups of mounting plates 9 in integrated tower 1, external pipeline 8 is penetrated between adjacent mounting plates 9 in integrated tower 1, water accumulation tray 2 is installed at the bottom of integrated tower 1.

[0036] The external pipe 8 here is made of heat-absorbing material, representing the external heat exchange equipment. It is arranged in three groups, one above the other, representing the high-temperature heat exchange zone, the medium-temperature heat exchange zone, and the low-temperature heat exchange zone. This arrangement allows for the use of external equipment operating at various temperatures, such as... Figure 2 There are three areas between the adjacent mounting plates 9 shown. The condensed water first comes to the first mounting plate 9. Each set of mounting plates 9 has a cooling fin to accelerate cooling. The water on the first mounting plate 9 is at a high temperature. When the temperature drops to a medium temperature, the first mounting plate 9 automatically opens. In this way, the condensed water on the first mounting plate 9 will continue to fall onto the second mounting plate 9, and so on, and finally be stored in the water collection tray 2.

[0037] A slot 16 is provided in the middle of the top of the mounting plate 9. A temperature detector 14 is installed on one side of the top of the mounting plate 9. A drive motor 19 is installed on one side inside the mounting plate 9. A tension plate 15 is slidably connected inside the slot 16. The tension plate 15 is foldable.

The top end of the movable ring 18 is connected to a limiting vertical shaft 20. The end of the limiting vertical shaft 20 is slidably connected to the slot 16. Specific Implementation Example 2:

[0040] Reference Figures 1-7 This integrated condensation and heat exchange device is used to condense external high-temperature gas and recover and utilize its heat. During operation, the external high-temperature gas is transported to the integrated tower 1 through the intake pipe 5 by the centrifugal intake pump 4. An air filter is installed at the inlet of the intake pump 4 to prevent dust, debris, and other contaminants from entering the integrated tower 1 and affecting its normal operation and condensation and heat exchange efficiency. The outer shell of the integrated tower 1 is made of high-strength, corrosion-resistant stainless steel, ensuring the stability of the equipment structure and resisting the effects of the external environment and internal high temperature, high pressure, and corrosive gases. The outer shell is also wrapped with insulation materials such as rock wool or polyurethane foam to reduce heat loss, improve energy efficiency, and lower the surface temperature of the equipment to prevent burns.

[0041] The condensate stored in the condensate tank 3 flows into the serpentine pipe group 7 inside the integrated tower 1 through the liquid inlet pipe 10 wrapped with a thermal insulation sleeve. The serpentine pipe group 7 is made of copper pipes with good thermal conductivity, which can quickly transfer the heat of high-temperature gas to the condensate, improving the condensation efficiency. The serpentine pipe group 7 is designed to be detachable, which is convenient for regular cleaning and maintenance to remove internal dirt and impurities, and improves the heat exchange efficiency. The condensate absorbs the heat of high-temperature gas in the serpentine pipe group 7, causing part of the gaseous substances to condense into liquid state. The warmed condensate flows back to the condensate tank 3 through the liquid outlet pipe 11 wrapped with a thermal insulation sleeve to form a cycle. The condensate tank 3 is equipped with a liquid level sensor that automatically replenishes the condensate when the liquid level is below the set value. A safety valve is also provided to automatically release pressure when the internal pressure is too high to ensure safety. The condensate tank 3 is also equipped with a cooling device to cool the returned high-temperature condensate to an appropriate temperature.

[0042] After entering the integrated tower 1, the high-temperature gas encounters the sieve plate 12 made of aluminum alloy. The sieve holes 13 on the sieve plate 12 are composed of different sizes of round holes, which can be adjusted according to the gas flow and properties. The gas is dispersed into multiple small gas streams, increasing the contact area between the gas and the serpentine pipe group 7, accelerating the cooling of the gas. The droplets formed by cooling fall downward under the action of gravity.

[0043] Three sets of mounting plates 9 made of aluminum alloy are provided inside the integrated tower 1. The external connecting pipes 8 passing through adjacent mounting plates 9 constitute high-temperature, medium-temperature, and low-temperature heat exchange zones. The external connecting pipes 8 are made of heat-absorbing materials, and their surfaces are specially treated, such as being plated with a layer of metal with better thermal conductivity or using a micro-channel structure, to increase the contact area and heat exchange coefficient with the condensate. The external connecting pipes 8 are used for heat exchange with external equipment with different temperature requirements.

[0044] The condensed high-temperature water first falls on the first layer of mounting plate 9, and the refrigerating sheet using semiconductor refrigerating sheet on the mounting plate 9 starts to work to accelerate the cooling of the water, at the same time, the heat of the high-temperature water is transmitted to the external equipment needing high-temperature heat through the external pipeline 8 to realize high-temperature heat exchange. The high-precision digital temperature detector 14 selected on one side of the top of the mounting plate 9 can monitor the temperature of the water in real time. When the temperature of the water is detected to decrease from high temperature to medium temperature, the temperature detector 14 will quickly transmit the temperature change signal to the driving motor 19 on one side of the mounting plate 9. After the driving motor 19 is started, the output shaft thereof drives the threaded shaft 17 in transmission connection to start rotating. Since the threaded shaft 17 is in threaded connection with the moving ring 18, with the rotation of the threaded shaft 17, the moving ring 18 will move linearly along the threaded shaft 17. The moving ring 18 is in threaded connection with the limiting vertical shaft 20 at the top end, the end of the limiting vertical shaft 20 is embedded into the slot 16 opened in the middle of the top end of the mounting plate 9 and is in sliding connection with the slot 16, so as to ensure the stability of the moving ring 18 in the moving process and make it only move linearly along the threaded shaft 17. With the movement of the moving ring 18, the foldable stretching plate 15 connected with it will be pulled and gradually unfolded, and the slot 16 originally closed by the stretching plate 15 will be opened, at this time, the water reaching medium temperature on the first layer of mounting plate 9 will fall into the second layer of mounting plate 9. On the second layer of mounting plate 9, the above-mentioned refrigeration, heat exchange and temperature monitoring process is repeated, when the water temperature decreases to low temperature, the second layer of mounting plate 9 is opened in the same way, and the low-temperature water falls into the third layer of mounting plate 9 for low-temperature heat exchange.

[0045] Finally, the condensed water cooled through the staged heat exchange falls into the water collecting base 2 for collection, the water collecting base 2 is provided with a water level alarm, which will alarm when the water level reaches a certain height to remind drainage, and a heating device is also arranged to prevent the condensed water from freezing in cold environment to affect the normal operation of the equipment. In addition, the equipment is also provided with a gas flow sensor and a condensate temperature sensor, which can automatically adjust the flow of the air inlet pump 4, the circulation speed of the condensate, the power of the cooling device of the condensing tank 3 and the power of the refrigerating sheet according to the monitoring data, so as to realize intelligent and efficient operation of the equipment and ensure that the equipment works in the best working condition. At the same time, the equipment is provided with a maintenance opening, which is convenient for periodic inspection and maintenance of the components such as the serpentine pipe group 7, the sieve plate 12, the mounting plate 9 and the external pipeline 8, and the condensing tank 3 is also provided with a blowdown opening, which is convenient for cleaning the impurities and precipitates inside. The connection parts of the air inlet pipeline 5 and the air inlet pump 4, the air inlet pump 4 and the integrated tower 1, the liquid inlet pipe 10 and the serpentine pipe group 7, the liquid outlet pipe 11 and the serpentine pipe group 7 and the external pipeline 8 and the mounting plate 9 all adopt sealing measures to prevent gas or liquid leakage.

[0046] In summary:

[0047] 1. In this equipment, after the high-temperature gas enters the integrated tower 1, it will encounter the sieve plate 12 made of aluminum alloy. The sieve holes 13 on the sieve plate 12 are a combination of round holes of different sizes, which can be adjusted according to the gas flow rate and properties to disperse the gas into multiple small airflows, increase the contact area between the gas and the serpentine tube group 7, accelerate the cooling of the gas, and the liquid droplets formed by cooling fall downwards under the action of gravity.

[0048] The integrated tower 1 is equipped with three sets of mounting plates 9, all made of aluminum alloy. The external pipes 8 that run through the adjacent mounting plates 9 form high-temperature, medium-temperature, and low-temperature heat exchange zones. The external pipes 8 are made of heat-absorbing material and have been specially treated, such as being coated with a metal with better thermal conductivity or using a microchannel structure to increase the contact area and heat exchange coefficient with condensate, so as to exchange heat with external equipment with different temperature requirements.

[0049] 2. In this equipment, the condensed high-temperature water first falls onto the first mounting plate 9. The cooling element on the mounting plate 9, using a semiconductor cooling chip, begins to work to accelerate the cooling of the water. Simultaneously, the heat from the high-temperature water is transferred to external equipment requiring high-temperature heat through the external pipe 8, achieving high-temperature heat exchange. A high-precision digital temperature detector 14, located on one side of the top of the mounting plate 9, monitors the water temperature in real time. When the water temperature drops from high to medium, the temperature detector 14 quickly transmits the temperature change signal to the drive motor 19 on one side of the mounting plate 9. After the drive motor 19 starts, its output shaft drives the threaded shaft 17, which is connected to it, to rotate. Because the threaded shaft 17 and the moving ring 18 are threadedly connected, the moving ring 18 moves linearly along the threaded shaft 17 as the threaded shaft 17 rotates. The top of the moving ring 18 is threadedly connected to a limiting vertical shaft 20. The end of the limiting vertical shaft 20 is embedded in and slidably connected to the slot 16 opened in the middle of the top of the mounting plate 9, ensuring the stability of the moving ring 18 during movement and ensuring that it can only move linearly along the threaded shaft 17. As the moving ring 18 moves, the foldable stretchable plate 15 connected to it is pulled and gradually unfolded, opening the slot 16 that was originally closed by the stretchable plate 15. At this time, the water that has reached a medium temperature on the first mounting plate 9 falls onto the second mounting plate 9. On the second mounting plate 9, the above-mentioned cooling, heat exchange, and temperature monitoring process is repeated. When the water temperature drops to a low temperature, the second mounting plate 9 opens in the same way, and the low-temperature water falls into the third mounting plate 9 for low-temperature heat exchange.
