Description

Technical Field

[0001] This utility model relates to the field of heat exchangers, and more particularly to a heat exchange device for improving the catalytic efficiency of sulfuric acid catalyst layers. Background Technology

[0002] In the sulfuric acid production process, the key reaction of sulfur dioxide to sulfur trioxide takes place in the catalyst layer, and this reaction is exothermic. If the heat generated during the reaction cannot be effectively managed, the temperature of the catalyst layer will become too high, causing a decrease in catalyst activity, which in turn seriously affects catalytic efficiency and reduces the quality and efficiency of sulfuric acid production.

[0003] According to a Chinese patent document (authorization announcement number: CN220818696U), a heat exchanger for sulfuric acid processing includes a heat exchanger body. Both sides of the top of the heat exchanger body have circular holes, into which insert rods are inserted. A base is provided on the outside of the heat exchanger body. A waterproof plate is provided on the top of the heat exchanger body. Locking blocks are fixed to the upper parts of both sides of the base. Both sides of the waterproof plate have locking grooves, into which the locking blocks are inserted. A vertical hole is provided in the center of each locking block, into which the insert rod is inserted. Locking components are provided on both sides of the waterproof plate for locking and fixing the insert rod and the locking grooves. Two sets of buffer mechanisms are provided at the bottom of the base, located at the bottom of the heat exchanger body. This invention not only protects the heat exchanger body but also saves on installation and disassembly procedures, making it simple to operate and convenient to use.

[0004] However, the above solution still has the following shortcomings when implemented:

[0005] Its heat exchange area is fixed, making it difficult to flexibly adjust the heat exchange efficiency according to different production conditions. When the production load changes, the fixed heat exchange area will either lead to overcooling or heating, resulting in energy waste, or it will be unable to meet the heat exchange requirements during high-load production. At the same time, when the ground space of the production site is limited, traditional heat exchange devices cannot be conveniently installed using the overhead space due to the lack of a suitable hoisting design, which further limits the flexibility and operability of the device layout and makes it difficult to adapt to the installation requirements under different site conditions. Utility Model Content

[0006] This invention addresses the technical problems existing in the prior art. The heat exchange area is fixed, making it difficult to flexibly adjust the heat exchange efficiency according to different production conditions. When the production load changes, the fixed heat exchange area either leads to overcooling or overheating, resulting in energy waste, or it cannot meet the heat exchange requirements during high-load production. At the same time, when the production site has limited floor space, traditional heat exchange devices lack suitable hoisting designs and cannot be easily installed using the overhead space, further limiting the flexibility and operability of the device layout and making it difficult to adapt to the installation requirements under different site conditions.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0008] A heat exchange device for improving the catalytic efficiency of a sulfuric acid catalyst layer includes an installation frame. A dynamic heat exchange pipe assembly is installed inside the installation frame. This assembly is used to open and close specific pipes, allowing for changes in the number of pipes and flow paths involved in the heat exchange, thereby flexibly adjusting the heat exchange area. An extended installation buffer structure is also provided at the top of the installation frame. This buffer structure is used to install the device in the top area and provides cushioning protection. A flow and temperature monitoring component is also installed on the inner wall of the installation frame. This component is used to monitor the fluid flow and temperature parameters in the heat exchange system in real time.

[0009] As a preferred embodiment of the present invention, the dynamic heat exchange pipeline assembly includes a main flow pipe, a first flow pipe is provided at the connection of the main flow pipe and near the bottom, a first connecting flange is provided at the tail end of the first flow pipe, a second connecting flange is provided at the connection of the first connecting flange, and a first connecting hose is installed on the second connecting flange.

[0010] As a preferred embodiment of this utility model, the bottom of the main flow pipe is further provided with a third connecting flange, and a fourth connecting flange is provided at the connection of the third connecting flange. A second connecting hose is installed inside the fourth connecting flange, and both the second connecting hose and the first connecting hose are covered with a metal corrugated pipe protective sleeve.

[0011] As a preferred embodiment of this utility model, a plurality of dynamic pipes are installed at the connection of the main flow pipe and above the first flow pipe, and two solenoid valves are provided at both ends of the plurality of dynamic pipes.

[0012] As a preferred embodiment of this utility model, the flow and temperature monitoring component includes a temperature sensor and a flow sensor. The flow sensor is installed to the right of the temperature sensor. The flow and temperature monitoring component is connected to the solenoid valve and the terminal of the control center. The dynamic pipe is inserted into the first flow pipe and is connected to the first flow pipe.

[0013] As a preferred embodiment of this utility model, the extended installation buffer structure includes an installation plate, a sliding rod installed at the center of the top of the installation plate, a fixed plate provided at the top of the sliding rod, a sliding plate sleeved on the outside of the sliding rod and located at the center, an extension plate installed at both ends of the sliding plate, a connecting support rod provided at the top of each of the two extension plates, and a plurality of dampers symmetrically installed between the fixed plate and the sliding plate and between the sliding plate and the installation plate, with buffer springs provided on the outside of each of the dampers.

[0014] As a preferred embodiment of this utility model, the mounting plate is fixedly installed on the top of the mounting frame, the connecting support rod is fixedly connected to the ceiling or bracket, and the sliding plate is slidably connected to the sliding rod.

[0015] The beneficial effects of this utility model are: by using a dynamic heat exchange pipeline assembly, specific pipelines can be opened and closed, the number of pipelines and flow paths involved in heat exchange can be changed, and the heat exchange area can be flexibly adjusted. When the production load is low, some pipelines can be closed to reduce the heat exchange area and avoid energy waste; when the production load is high, more pipelines can be opened to increase the heat exchange area, meet the demand for efficient heat exchange, and significantly improve energy utilization efficiency and production efficiency.

[0016] With excellent vibration protection performance, the extended installation buffer structure allows the device to be installed in the top area. The damper and buffer spring work together to buffer and protect the device, reducing structural damage caused by vibration, extending the service life of the device, and reducing vibration-induced noise, thus improving the working environment. In addition, the pipeline connection uses a first connecting hose and a second connecting hose, and is covered with a metal corrugated pipe protective sleeve, which further enhances the vibration resistance, prevents the interface from being damaged by vibration, and reduces the risk of leakage.

[0017] Precise operating parameter monitoring: The flow and temperature monitoring components monitor the fluid flow and temperature parameters in the heat exchange system in real time and are connected to the solenoid valve and control center terminal. This allows for timely and accurate feedback of operating data to the operators, facilitating precise control of the opening and closing of dynamic pipelines based on actual working conditions. This ensures that the heat exchange process is always in optimal operating condition, improving the stability and reliability of the heat exchange device. Attached Figure Description

Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0027] Example

[0028] Please see Figure 1-4This heat exchange device is composed of several key components working together. Among them, the mounting frame 1, dynamic heat exchange pipeline assembly, extended installation buffer structure, and flow and temperature monitoring assembly are particularly important. As the basic support structure of the entire device, the mounting frame 1 is usually welded from high-strength steel, which has sufficient strength and stability to withstand various loads during the operation of the heat exchange device. Its frame design fully considers the installation requirements of other components, and reserves precise installation interfaces and fixed positions to facilitate the orderly assembly of each component, ensuring that each component works closely together and collaboratively during operation, and maintaining the stable operation of the entire heat exchange device.

[0029] Main flow pipe 201 and its branches: The main flow pipe 201 is the "main artery" of the entire heat exchange system. It is generally made of corrosion-resistant special alloy material, such as molybdenum-containing stainless steel, to resist the erosion of corrosive fluids such as sulfuric acid. Its pipe diameter is precisely designed according to the fluid flow and pressure requirements in actual production to ensure that the main fluid can be transmitted smoothly and efficiently in the pipe. At the connection point near the bottom of the main flow pipe 201, the first flow pipe 202 is carefully set up. This pipe branch plays an important role in guiding some fluids into specific heat exchange paths. It can flexibly adjust the proportion of fluids participating in heat exchange according to the production conditions to optimize the heat exchange effect. For example, under certain conditions, it is necessary to perform separate enhanced heat exchange treatment on some fluids. The first flow pipe 202 can accurately guide the fluid of the corresponding flow rate into the specific process.

[0030] Flange connection mechanism: The tail end of the first flow pipe 202 is equipped with a standard first connecting flange 203. Multiple bolt holes are evenly distributed on the flange for connection with the matching second connecting flange 204. This flange connection method uses bolts to tightly fasten the two flanges together. A gasket, such as a polytetrafluoroethylene (PTFE) gasket, is usually added to the flange sealing surface. Utilizing its good flexibility and corrosion resistance, the gasket undergoes elastic deformation under the pressure generated by tightening the bolts, filling the tiny gaps on the flange sealing surface, thereby forming a reliable sealing effect and effectively preventing fluid leakage. This connection method has significant advantages in practical applications. When the pipeline assembly needs maintenance, repair, or replacement, the two flanges can be easily separated simply by unscrewing the bolts, achieving quick disassembly and installation, greatly improving the convenience and efficiency of equipment maintenance.

[0031] Connecting hose and protective sleeve: At the bottom of the main flow pipe 201, a third connecting flange 206 is also installed, and a matching fourth connecting flange 207 is installed at the connection point. Inside the fourth connecting flange 207, a second connecting hose 208 is installed. Together with the previously mentioned first connecting hose 205, they are all made of high-performance fluororubber or polytetrafluoroethylene (PTFE) and other flexible materials. These flexible materials have excellent corrosion resistance, can adapt to highly corrosive media such as sulfuric acid, and also possess good flexibility and extensibility. During the operation of the heat exchange device, the pipes will experience thermal expansion and contraction due to temperature changes. Vibrations from the equipment itself and the surrounding environment will also affect the pipes. At this time, the connecting hose, with its inherent flexibility, can effectively prevent thermal expansion and contraction. To effectively compensate for these displacements and prevent pipe ruptures or leaks caused by rigid connections being unable to adapt to displacement, ensuring the continuity and safety of the heat exchange process, a metal corrugated protective sleeve is installed on the outer layer of the connecting hose to further improve its performance. The metal corrugated protective sleeve is generally made of stainless steel. Its unique corrugated structure not only significantly enhances the mechanical strength of the connecting hose, enabling it to resist possible external collisions and frictions and reduce the risk of physical damage, but also plays a certain role in heat insulation during the heat exchange process. By reflecting and blocking some heat transfer, it reduces the heat exchange between the fluid inside the connecting hose and the external environment, maintains the stability of the heat distribution inside the heat exchange system, and thus ensures that the heat exchange efficiency is not affected by too many external factors.

[0032] Solenoid valves 210 control dynamic pipes 209: Several dynamic pipes 209 are installed at the connection of the main flow pipe 201 and above the first flow pipe 202. The number and diameter of these dynamic pipes 209 are precisely designed and configured according to the specific heat exchange requirements of the heat exchange device. Two solenoid valves 210 are installed at both ends of each dynamic pipe 209. As a key component for controlling the opening and closing of the dynamic pipes 209, the solenoid valve 210 has a sophisticated internal structure. Its core component, the electromagnetic coil, generates a strong electromagnetic force when energized. This electromagnetic force can attract the valve core to move, thereby changing the on / off state of the valve. In the actual heat exchange process, the control center adjusts the flow rate and... The data fed back by the temperature monitoring component accurately determines the current production condition. For example, when the production load decreases and the heat exchange demand decreases, the control center sends a power-off signal to the solenoid valves 210 at both ends of the dynamic pipeline 209. The electromagnetic force disappears, and the valve core closes the valve under the action of the return spring. The dynamic pipeline 209 closes accordingly, reducing the number of pipelines and flow paths involved in heat exchange, reducing the heat exchange area, and avoiding excessive energy consumption. Conversely, when the production load increases and the heat exchange demand increases, the control center sends a power-on signal, the solenoid valve 210 opens, the dynamic pipeline 209 is open, more fluid can participate in heat exchange, the heat exchange area is increased, and the demand for efficient heat exchange is met.

[0033] The extended installation buffer structure uses mounting plate 401 as the basic connecting component. Mounting plate 401 is firmly fixed to the top of mounting frame 1 using high-strength bolts, ensuring a tight connection between the entire buffer structure and the main body of the heat exchange device. A sliding rod 402 is vertically installed at the top center of mounting plate 401. The sliding rod 402 is generally made of surface-hardened alloy steel to ensure sufficient strength and wear resistance. A fixing plate 403 is fixed to the top of the sliding rod 402. The fixing plate 403 is used to connect and fix to the ceiling or specially constructed supports and other top structures, typically using reliable methods such as welding or bolting. A sliding plate 404, which can slide up and down along the sliding rod 402, is fitted at the outer center of the sliding rod 402. The sliding plate 404 has two ends... An extension plate 405 is horizontally installed, which further expands the connection range of the structure and enhances the stability of the connection with the top structure. The top of each extension plate 405 is equipped with a connecting support rod 406, which is stably connected to the ceiling or bracket by bolts or welding. Several dampers 407 are symmetrically installed between the fixed plate 403 and the sliding plate 404, and between the sliding plate 404 and the mounting plate 401. The number and specifications of the dampers 407 are reasonably selected according to factors such as the weight of the heat exchange device and the expected vibration intensity. A buffer spring 408 is arranged around the outside of the damper 407. The buffer spring 408 is made of high-quality spring steel and undergoes a precise heat treatment process, which gives it good elasticity and fatigue life.

[0034] When the heat exchanger is subjected to vibrations from its own operation and the surrounding environment, the vibration is first transmitted to the mounting frame 1, and then to the extended mounting buffer structure. At this time, the sliding plate 404 will have relative displacement on the sliding rod 402, and the damper 407 will start to function. Its interior is usually filled with high-viscosity silicone oil or other damping media. When the sliding plate 404 moves, the piston inside the damper 407 moves in the damping media. Due to the viscous resistance of the damping media, the piston movement is hindered, thereby converting the mechanical energy of the vibration into heat. The damper 407 can dissipate and effectively slow down the movement speed of the sliding plate 404, playing an initial shock absorption role. After the initial shock absorption by the damper 407, the remaining part of the vibration energy is absorbed by the buffer spring 408. When subjected to vibration impact, the buffer spring 408 will undergo elastic deformation, converting the vibration energy into the elastic potential energy of the spring and storing it. Then, during the process of the spring recovering its deformation, this part of the energy is slowly released, further buffering the vibration impact, protecting the main body of the heat exchange device from vibration damage, extending the service life of the device, and reducing the noise caused by vibration, creating a better working environment.

[0035] Sensor Working Principle: The system consists of a temperature sensor 301 and a flow sensor 302 working together. The temperature sensor 301 can be categorized into several types based on its working principle. For example, a thermocouple-type temperature sensor 301 utilizes the thermoelectric effect; when two different metal conductors form a closed circuit, a thermoelectric electromotive force (EMF) is generated in the circuit when the temperatures of the two junctions are different. The fluid temperature can be calculated by measuring the magnitude of the EMF. A resistance temperature sensor 301 is based on the thermal resistance effect; the resistance of certain metals or semiconductors changes with temperature, and the fluid temperature is obtained by measuring the change in resistance. Similarly, the flow sensor 302 also comes in various types, such as electromagnetic flow meters which utilize the principle of electromagnetic induction. When a conductive fluid flows in a magnetic field, it cuts magnetic lines of force, generating an induced electromotive force. The magnitude of the induced electromotive force is proportional to the fluid velocity, and the fluid flow rate can be calculated by measuring the induced electromotive force. A vortex flow meter utilizes the Karman vortex street principle. When a fluid flows through a non-streamlined obstruction fluid perpendicular to the fluid flow direction, a regular vortex array is generated alternately on both sides downstream of the obstruction fluid. The frequency of the vortex is proportional to the fluid velocity, and the fluid flow rate is measured by detecting the vortex frequency. In this heat exchange device, the flow sensor 302 is installed to the right of the temperature sensor 301. They are precisely installed at specific locations in the heat exchange pipeline to ensure accurate measurement of the flow rate and temperature parameters of the fluid participating in the heat exchange.

[0036] This component is closely connected to the solenoid valve 210 in the dynamic heat exchange pipeline assembly and the control center terminal via data transmission lines. Temperature sensor 301 and flow sensor 302 convert the real-time monitored fluid flow and temperature data into electrical signals, which are then quickly and accurately transmitted to the control center terminal via shielded cables and other data transmission lines. The control center typically consists of a high-performance industrial computer and supporting data processing software, possessing powerful data processing and analysis capabilities. Operators pre-set ideal threshold ranges for flow and temperature in the control center based on actual production process requirements and heat exchange needs. After receiving the monitoring data, the control center processes the real-time data... By comparing and analyzing the data with preset thresholds, if the data is found to deviate from the ideal range, it is determined that the current production conditions have changed. For example, when the flow rate is lower than the preset lower limit and the temperature is higher than the preset upper limit, the control center determines that the heat exchange efficiency is insufficient and the heat exchange area needs to be increased. Therefore, it sends an energizing command to the solenoid valves 210 at both ends of the dynamic pipe 209 to open more dynamic pipes 209, increase the heat exchange area, and improve the heat exchange efficiency. Conversely, when the flow rate is too high and the temperature is too low, the control center sends an energizing command to close some dynamic pipes 209, reduce the heat exchange area, avoid energy waste, and ensure that the heat exchange process is always in the best operating state.

[0037] Work process summary

[0038] Installation Phase: During the installation of this heat exchange device, the device is first connected to the top structure using the extended installation buffer structure. Construction personnel reliably fix the connecting support rod 406 to the ceiling or a pre-built sturdy bracket. The connection method can be welding or high-strength bolt tightening, depending on the actual situation, to ensure a secure connection. Simultaneously, the mounting plate 401 is firmly fixed to the top of the mounting frame 1 with bolts, ensuring a tight connection between the extended installation buffer structure and the main body of the heat exchange device. During installation, the verticality of the sliding rod 402 is carefully adjusted to ensure that the sliding plate 404 can slide smoothly up and down on the sliding rod 402. After installation, the damper 407 and buffer spring 408 are inspected and adjusted to ensure they are in normal working condition, providing reliable vibration buffer protection for subsequent device operation.

[0039] Operation monitoring phase: After the heat exchange unit is put into operation, the flow and temperature monitoring components immediately enter the working state. Temperature sensor 301 and flow sensor 302 continuously and in real time monitor the flow and temperature parameters of the fluid in the heat exchange system. These parameters are continuously transmitted to the control center terminal in the form of electrical signals through the data transmission line. The control center displays and stores this data in real time, so that operators can check the operating status of the heat exchange unit at any time. At the same time, the control center also performs real-time analysis of the data to determine whether the heat exchange process is normal, providing accurate data basis for subsequent heat exchange regulation.

[0040] During the heat exchange regulation phase: Based on the received flow and temperature data, and combined with preset production parameters, the control center determines the current production condition in real time. If the production load is low, for example, the flow data is near the lower limit of the preset range and the temperature data is below the ideal temperature range, the control center determines that the heat exchange demand has decreased and sends a power-off signal to the solenoid valves 210 at both ends of the dynamic pipe 209 in the dynamic heat exchange pipe assembly, closing part of the dynamic pipe 209. This operation reduces the number of pipes and flow paths involved in heat exchange, reduces the heat exchange area, and avoids energy waste caused by excessive heat exchange. Conversely, if the production load is high, the flow data exceeds the upper limit of the preset range, and the temperature data is above the ideal temperature range, the control center determines the heat exchange demand has decreased. If the heat exchange efficiency is insufficient, the control center will send an energizing signal to the solenoid valve 210 to open more dynamic pipes 209, increasing the heat exchange area and meeting the requirements for high-efficiency heat exchange. During the entire heat exchange adjustment process, the first connecting hose 205, the second connecting hose 208, and their outer metal corrugated protective sleeve, together with the extended installation buffer structure, work in concert. The connecting hoses compensate for pipe displacement due to their flexibility, the metal corrugated protective sleeves enhance the mechanical strength and thermal insulation performance of the connecting hoses, and the extended installation buffer structure effectively buffers vibrations. Together, they ensure the stable operation of the device, ensuring that the heat exchange process is always in the best condition, significantly improving the catalytic efficiency of the sulfuric acid catalyst layer, and enhancing the quality and efficiency of sulfuric acid production.
