Description

Technical Field

[0001] The present application relates to the field of coal mine machinery and environmental protection technology, and in particular to a smoke treatment device for a monorail heat exchanger. Background Art

[0002] In the modernization process of the coal industry, monorail crane transportation has gradually become an important part of mine transportation due to its advantages such as efficient transportation capacity, flexible material lifting methods and fast track installation. However, in the daily maintenance of monorail crane locomotives, especially the cleaning of heat exchangers, there is a certain contradiction between its operation method and the requirements of environmental protection and personnel health.

[0003] At present, the commonly used method for cleaning the heat exchanger of a monorail crane locomotive is to directly blow away the dust and impurities in the heat exchanger with compressed air. This method is simple and easy to use, and can quickly remove the dirt attached to the heat exchanger to ensure the normal operation of the equipment.

[0004] Although using compressed air to clean the heat exchanger directly can achieve a quick cleaning effect, this process will cause a large amount of smoke and particulate harmful substances to be blown directly into the air in the mine tunnel, thereby polluting the air environment on the downwind side, reducing air quality, and posing a potential threat to the health of miners. Especially in mine tunnels with poor ventilation conditions, this pollution is more likely to accumulate, and in severe cases it may even endanger the lives of workers, and cannot meet the safety and environmental protection requirements of modern coal mine monorail crane transportation systems. Summary of the invention

[0005] An embodiment of the present application provides a smoke treatment device for a monorail heat exchanger to deal with the pollution problem of the working environment and air quality caused by the smoke generated during the operation of the heat exchanger.

[0007] A negative pressure integrator and a spray atomization device are arranged in the housing along the direction from the air inlet to the air outlet;

[0008] It also includes an annular air duct; the annular air duct is arranged at the air outlet and is fixedly connected to the shell.

[0009] In a feasible implementation, the shell is a cylindrical structure, and the centers of the negative pressure integrator and the spray atomization device pass through the axis of the cylindrical structure.

[0010] In a feasible implementation, one side of the negative pressure integrator passes through the shell and is connected to a first pipeline.

[0011] In a feasible implementation, one side of the spray atomization device penetrates through the housing and is connected to a second pipe. In a feasible implementation, the spray atomization device is an annular structure, and a plurality of annular atomization nozzles are evenly distributed on the annular structure.

[0012] In a feasible implementation, the negative pressure integrator includes a plurality of integrated units along the circumference of the shell, and the negative pressure integrator is connected to the inner wall of the shell through a fixing claw. In a feasible implementation, the annular air cylinder is clamped to the air outlet of the shell by a clamp.

[0013] In a feasible implementation, the diameter of the annular wind cylinder is 600 mm.

[0014] In a feasible implementation, the shell is made of stainless steel.

[0015] In a feasible implementation, the inner wall of the shell is provided with an anti-corrosion coating.

[0016] A smoke treatment device for a monorail heat exchanger provided in an embodiment of the present application has a negative pressure integrator arranged at the air inlet of the device, which can generate a strong negative pressure effect, effectively attract and concentrate smoke generated from the outside, and ensure that the smoke is quickly captured at the early stage of exhaust, thereby avoiding the diffusion and secondary pollution of the smoke. Subsequently, the water is finely atomized and fully mixed with the smoke through a spray atomization device, which not only achieves the wetting of the smoke, but also promotes the sedimentation of the smoke particles, greatly improving the purification efficiency of the smoke. The design of the annular wind tube being fixedly connected to the shell enhances the structural stability and dust removal effect of the entire device, and reduces the risk of damage caused by vibration or external force. The smoke purification treatment is achieved through physical methods (negative pressure suction and spray atomization), without the use of chemical agents, and therefore has the characteristics of being environmentally friendly and pollution-free.

[0022] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0023] Monorail crane transportation is widely used in my country's coal industry due to its high transportation efficiency, flexible material hoisting methods, and fast track installation. At present, when the monorail crane locomotive cleans the heat exchanger, it directly uses compressed air to clean it, which will cause the smoke and particulate harmful substances in the heat exchanger to be directly blown into the wind flow, polluting the downwind air and reducing the air quality. In serious cases, it may endanger the personal safety of employees and cannot meet the needs of monorail crane system construction.

[0024] The specific structure of a smoke treatment device for a monorail heat exchanger provided in the present application is described in detail below in conjunction with the accompanying drawings.

[0025] Reference Figure 1 and Figure 2 As shown, an embodiment of the present application provides a smoke treatment device for a monorail heat exchanger, comprising: a shell 1, wherein an air inlet and an air outlet are respectively provided on both sides of the shell 1, to ensure that the dust blown out of the heat exchanger enters from the air inlet and is discharged from the air outlet after being processed, thereby forming a complete airflow channel and improving the efficiency of smoke treatment.

[0026] A negative pressure integrator 2 and a spray atomizer 3 are arranged in the shell 1 along the direction from the air inlet to the air outlet. The negative pressure integrator 2 generates negative pressure at the air inlet, effectively attracting external smoke and dust into the device, thereby ensuring efficient collection of the smoke and dust; the spray atomizer 3 atomizes water and mixes it with the incoming smoke and dust to achieve wetting and sedimentation of the smoke and dust, thereby improving the purification effect of the smoke and dust.

[0027] It also includes an annular wind tube 4; the annular wind tube 4 is arranged at the air outlet and is fixedly connected to the shell 1. The annular wind tube 4 helps to evenly distribute the airflow, reduce the turbulence of the airflow at the air outlet, improve the efficiency of exhausting gas, and enhance the structural stability of the device.

[0028] The embodiment of the present application provides a smoke treatment device for a monorail heat exchanger. By respectively setting an air inlet and an air outlet on both sides of the shell 1, it is ensured that the dust blown out of the heat exchanger can smoothly enter from the air inlet and be discharged from the air outlet after being processed, forming a complete air flow channel, thereby improving the fluidity and efficiency of the smoke treatment process. The negative pressure integrator 2 is installed at the air inlet position, which can generate negative pressure there, thereby effectively attracting external smoke and dust into the device, ensuring efficient collection of smoke and dust. The spray atomization device 3 is located after the negative pressure integrator, which can atomize water and mix it with the incoming smoke and dust. This process can not only make the smoke and dust moist, but also is more conducive to the sedimentation of smoke and dust particles, thereby significantly improving the smoke and dust treatment effect. The annular wind tube 4 is installed at the air outlet and fixedly connected to the shell 1. It can not only help to evenly distribute the airflow and reduce the turbulence of the airflow at the air outlet, thereby improving the fluidity of the exhaust gas, but also enhance the overall structural stability of the device to ensure long-term stable operation.

[0029] Reference Figure 1 and Figure 2 As shown, in some embodiments, the shell 1 is a cylindrical structure, and the centers of the negative pressure integrator 2 and the spray atomization device 3 pass through the axis of the cylindrical structure. The cylindrical shell and the symmetrical distribution design ensure uniform distribution of the airflow, reduce the resistance of the airflow in the shell, and improve the processing efficiency.

[0030] The cylindrical shell structure combined with the central arrangement of the negative pressure integrator and the spray atomizer ensures that the airflow can be evenly distributed along the axis of the cylinder after entering the device. This design reduces the deviation and eddy flow of the airflow in the shell, allowing the smoke to contact the spray atomized water droplets more evenly, thereby improving the wetting and sedimentation efficiency of the smoke. The symmetrical distribution design is not only beautiful, but more importantly, it reduces the resistance of the airflow in the shell. The airflow flows smoothly in the cylinder, reducing the energy loss caused by resistance, so that more energy can be used for the collection and treatment of smoke, thereby improving the treatment efficiency of the entire device. The cylindrical shell structure itself has good stability and load-bearing capacity, and the central arrangement of the negative pressure integrator and the spray atomizer further enhances the symmetry of the structure, making the device more stable and reliable during operation. This design reduces the risk of structural deformation or damage caused by vibration or external force, and extends the service life of the device.

[0031] Reference Figure 1 and Figure 2 As shown, in some embodiments, one side of the negative pressure integrator 2 passes through the shell 1 and is connected to a first pipe 21, and the first pipe 21 is connected to an external high-pressure air duct to ensure smooth introduction of airflow.

[0032] The first pipe 21 allows high-pressure wind to smoothly pass through the interface into the interior of the device. This direct connection method reduces the resistance and turbulence of the airflow during the introduction process, ensuring that pollutants such as smoke and dust can be efficiently sucked into the device for subsequent treatment. The presence of the first pipe 21 makes the smoke treatment device more flexible in installation and use. Appropriate pipes and connection methods can be selected according to actual needs, and the device can be flexibly arranged near the source of smoke and dust that needs to be treated, so as to maximize its role. After the device has been running for a period of time, the first pipe 21 and the external pipes connected to it may affect the smooth introduction of the airflow due to dust accumulation or blockage. At this time, the user can restore its normal function by disassembling or cleaning the first pipe 21 and the pipes connected to it, thereby ensuring the long-term stable operation of the device.

[0033] Reference Figure 1 and Figure 2 As shown, in some embodiments, one side of the spray atomization device 3 passes through the shell 1 and is connected to a second pipe 31. The second pipe 31 is convenient for connecting to a high-pressure water source to ensure smooth spray atomization. Both the first pipe 21 and the second pipe 31 are detachable for easy connection, maintenance and replacement, thereby improving the ease of use of the device.

[0034] The presence of the second pipe 31 enables the spray atomization device 3 to be easily connected to an external high-pressure water source, thereby ensuring the smooth operation of the spray atomization. The high-pressure water source is stably supplied to the spray atomization device 3 through the second pipe 31, and after atomization, fine water mist is formed, which is fully mixed with the smoke entering the device to achieve the wetting and sedimentation of the smoke. Both the first pipe 21 and the second pipe 31 are detachable. After the device has been running for a period of time, the spray atomization device 3 or the external pipe may need maintenance and replacement due to wear, blockage, etc. At this time, you only need to simply disassemble the quick connector to take out the parts that need maintenance or replacement, and then connect the new parts through the quick connector. The whole process is quick and efficient.

[0035] Reference Figure 1 and Figure 2 As shown, in some embodiments, the spray atomization device 3 is an annular structure, and a plurality of atomization nozzles are evenly distributed on the annular structure. The plurality of atomization nozzles can spray water mist more evenly, increase the contact area with the smoke, and improve the wetting and sedimentation effect of the smoke.

[0036] By evenly distributing multiple atomizing nozzles on the annular structure, a continuous or nearly continuous annular water curtain can be formed. The annular water curtain can significantly increase the contact area between the water mist and the smoke, which helps to more effectively capture and wet the smoke particles and promote their sedimentation. Compared with single-point injection, the annular structure can ensure that the water mist is more evenly distributed in the entire space, avoid local over-wetting or over-drying, and improve the overall processing efficiency. The arrangement of multiple atomizing nozzles enables the water mist to more comprehensively cover the airflow and smoke entering the device. The contact area between the water mist and the smoke is significantly increased, which is conducive to the wetting and sedimentation of the smoke particles. Due to the increase in weight, the smoke particles after being wetted are more likely to settle under the action of gravity, thereby improving the purification effect of the smoke. By designing the spray atomization device 3 as an annular structure and evenly distributing multiple atomizing nozzles, it can be ensured that the water mist is sprayed more evenly inside the device.

[0037] Although the spray atomization device 3 adopts a design of multiple nozzles, the spraying of water mist is more uniform and efficient, which can actually reduce the consumption of water resources and energy. At the same time, due to the improvement of purification efficiency, the operation time of the device can also be shortened accordingly, further reducing energy consumption.

[0038] Reference Figure 1 and Figure 2 As shown, in some embodiments, the negative pressure integrator 2 includes several integrated units along the circumference of the shell 1, and the negative pressure integrator 2 is connected to the inner wall of the shell 1 through fixing claws. The design of the fixing claws ensures the stable installation of the negative pressure integrator 2, prevents loosening due to vibration, and improves the reliability and safety of the device; a filter is provided inside the negative pressure integrator 2, and the filter can preliminarily filter the incoming smoke and dust, reduce large particles entering the subsequent processing links, and extend the service life of the spray atomization device 3.

[0039] The negative pressure integrator 2 is closely connected to the inner wall of the shell 1 through the fixing claws, ensuring that the negative pressure integrator 2 can remain stable when running at high speed or subjected to external impact. The circumferential integrated units of the negative pressure integrator 2, each integrated unit is a relatively independent unit body, which can be maintained and replaced separately. When an integrated unit fails or needs to be cleaned, it can be quickly located and processed without disassembling or shutting down the entire negative pressure integrator 2. The fixing claw effectively prevents the loosening or falling off of the negative pressure integrator 2 due to vibration through its strong fixing force and stability, thereby improving the reliability and safety of the entire device. The filter net set inside the negative pressure integrator 2 can initially filter the smoke and dust entering the device, and effectively intercept large particles before the subsequent processing link. This design not only reduces the impact and wear of large particles on the spray atomization device, prolongs its service life, but also improves the efficiency and effect of the entire smoke and dust treatment process. Through the preliminary filtration of the filter net, the smoke and dust entering the spray atomization device 3 are more delicate and uniform, which is conducive to the full mixing and sedimentation of the water mist.

[0040] Reference Figure 1 and Figure 2 As shown, in some embodiments, the annular air duct 4 is clamped to the air outlet of the shell 1 by a clamp. The design of the clamp makes the connection between the annular air duct 4 and the shell 1 more convenient and firm, and is easy to install and disassemble, while ensuring the uniform distribution of the airflow at the air outlet, reducing the turbulence of the airflow, and improving the quality of the exhaust gas.

[0041] The clamp design ensures that the connection between the annular wind tube 4 and the shell 1 is firm and reliable. During the operation of the device, even if it is impacted or vibrated by the airflow, the clamp can maintain its connection stability and prevent the annular wind tube 4 from loosening or falling off. When the airflow passes through the annular wind tube 4, its flow rate and flow direction are further adjusted and optimized, reducing the turbulence and vortex phenomena of the airflow. By reducing the turbulence and vortex phenomena of the airflow, the design of the annular wind tube 4 also helps to improve the fluidity and efficiency of the smoke treatment process. During the smoke treatment process, the gas treated by the spray atomization device may still contain a certain amount of tiny particles. The uniform airflow distribution of the annular wind tube 4 helps these tiny particles to be better discharged from the outside of the device, thereby improving the purification effect of the smoke.

[0042] Reference Figure 1 and Figure 2 As shown, in some embodiments, the diameter of the annular air cylinder 4 is 600 mm. The appropriate diameter size ensures the uniform distribution of the airflow at the air outlet, avoids excessive local pressure caused by concentrated airflow, and improves the stability and treatment effect of the airflow.

[0043] The diameter of 600mm allows sufficient internal space for the annular wind tube 4, allowing the airflow to gradually diffuse and reach a balanced state during the flow process. Excessive local pressure caused by the concentration of airflow at the air outlet is avoided, ensuring the uniform distribution of airflow. Evenly distributed airflow helps to reduce turbulence and vortex phenomena, and improve the stability and discharge effect of airflow. The appropriate diameter size also helps to reduce the energy consumption and noise level of the device. When the airflow flows smoothly in the wind tube, the energy loss and noise pollution caused by poor airflow or turbulence are reduced. This not only improves the operating efficiency of the device, but also improves the working environment. The diameter of 600mm also provides strong support for the structural stability of the annular wind tube 4. The larger diameter makes the wind tube more stable when subjected to the impact of airflow, reducing the risk of performance degradation or damage due to vibration or deformation.

[0044] Reference Figure 1 As shown, in some embodiments, the shell 1 is made of stainless steel, which has good corrosion resistance, ensuring the stability and durability of the shell 1 in long-term use.

[0045] During the smoke treatment process, the device often comes into contact with various corrosive substances, such as acidic gases, moisture, etc. Stainless steel can effectively resist the erosion of these corrosive substances, ensuring that the shell 1 will not be damaged by corrosion during long-term use, thereby extending the service life of the equipment. Stainless steel materials are not only corrosion-resistant, but also have high strength and hardness. This enables the shell 1 to maintain a stable shape and structure when subjected to internal airflow and external impact, and is not prone to deformation or cracking. The surface of stainless steel is smooth and not easy to adhere to dirt and dust. This makes the shell 1 more convenient and quick to clean and maintain, reducing the risk of equipment performance degradation or damage caused by improper cleaning. In addition, stainless steel materials also have good antibacterial properties, which helps to reduce the risk of bacterial growth and cross infection. Stainless steel is a recyclable environmentally friendly material. When the device is scrapped or updated, the stainless steel shell can be recycled and reused, reducing resource waste and environmental pollution. This meets the current social requirements for environmental protection and sustainable development.

[0046] Reference Figure 1 As shown, in some embodiments, the inner wall of the shell 1 is provided with an anti-corrosion coating, which can effectively prevent the inner wall of the shell from being corroded by smoke and water mist, thereby extending the service life of the device.

[0047] The main function of the anti-corrosion coating is that it can effectively isolate smoke, water mist and other corrosive substances from direct contact with the inner wall of the shell 1. By coating the anti-corrosion coating on the inner wall, a protective layer can be formed to effectively block the erosion of these corrosive substances, thereby protecting the integrity and stability of the shell 1. In addition, the anti-corrosion coating also has certain wear resistance and impact resistance. During the smoke treatment process, the scouring of airflow and water mist and the impact of particulate matter may cause certain wear on the inner wall of the shell 1. The anti-corrosion coating can resist the effects of these external forces, reduce the degree of wear, and further extend the service life of the device.

[0048] According to the above technical features, the working principle of the smoke treatment device for a monorail heat exchanger provided by the present application in an actual application scenario is:

[0049] First, the external dust-containing airflow is introduced into the device through the air inlet set on the shell 1. The negative pressure integrator 2 located at the air inlet will generate negative pressure, effectively attracting the external dust-containing airflow into the device, and ensuring the efficient collection of smoke and dust. A filter is provided inside the negative pressure integrator 2, which can initially filter out larger particles of impurities and reduce damage to subsequent processing components. The spray atomization device 3 starts working. The spray atomization device 3 is connected to the external high-pressure water source through the second pipe 31, atomizes the water into fine droplets, and mixes them with the smoke and dust particles in the airflow. This process can make the smoke and dust particles wet, increase their weight, and make them easier to settle. The design of multiple atomization nozzles ensures the uniform distribution of water mist, increases the contact area between smoke and dust particles and water mist, and thus improves the purification efficiency. The treated airflow continues to move along the inside of the shell 1 and finally reaches the air outlet. In this process, the annular wind tube 4 installed at the air outlet is connected to the shell 1 through a clamp, which enhances the structural stability of the device, evenly distributes the airflow, reduces the turbulence of the airflow at the air outlet, and improves the fluidity and efficiency of the smoke and dust treatment process. The reasonable diameter design of the annular air cylinder 4 (for example, 600 mm) ensures the uniform distribution of the airflow at the air outlet, avoids the situation of excessive local pressure, and further improves the stability and treatment effect of the airflow. In order to ensure the long-term stable operation of the device, the first pipe 21 and the second pipe 31 are designed as quick connectors, which are easy to connect and disassemble, and convenient for users to maintain and replace. In addition, the shell 1 is made of stainless steel, and an anti-corrosion coating is provided on its inner wall to improve the corrosion resistance and service life of the device.
