Description

Technical Field

[0001] This application relates to the technical field of pipeline soot blowing equipment, and in particular to a pipeline soot blowing device based on a blasting type pulse conveyor. Background Art

[0002] In many fields of industrial production, pipeline systems, as key infrastructure for material transportation and gas transmission, are widely used in industries such as chemical engineering, electric power, metallurgy, and building materials. However, as the production process continues, various dusts, impurities, and material particles are extremely likely to adhere to the inner wall of the pipeline. These clogging ash materials adhering to the inner wall of the pipeline bring many severe problems to industrial production. The accumulation of dust significantly increases the roughness of the pipeline, causing a substantial increase in the frictional resistance when gas or materials flow through the pipeline. This directly leads to a sharp decline in the transportation efficiency. In order to maintain the normal production flow, enterprises have to increase the energy consumption of power equipment, thus greatly increasing the production cost. Take a chemical enterprise as an example. Due to severe ash accumulation in its main raw material transportation pipeline, the transportation energy consumption increased by 30% within half a year. If the pipeline ash is not cleaned for a long time, the effective flow cross-sectional area of the pipeline will gradually decrease, and in severe cases, even pipeline blockage will occur. Once the pipeline is blocked, the entire production process will be forced to stop. Enterprises not only need to invest a large amount of manpower and material resources for emergency repair, but also suffer huge economic losses due to production suspension. In an accident of a primary flue gas duct blockage in a power enterprise, the repair took up to 3 days, and the direct economic loss was as high as several million yuan.

[0003] Traditional pipeline ash cleaning methods mainly include mechanical ash cleaning and manual ash cleaning. Mechanical ash cleaning usually uses tools such as rotary scrapers and ash cleaning brushes. Although this method can remove some accumulated ash to a certain extent, it has the disadvantages of incomplete ash cleaning and easy scratching and damage to the inner wall of the pipeline. Moreover, for some complex pipeline structures or narrow pipeline sections, mechanical tools are difficult to operate, and the ash cleaning effect is greatly reduced. Manual ash cleaning consumes a large amount of manpower and time, has a very high labor intensity, and extremely low ash cleaning efficiency. In pipelines with corrosive or high-temperature environments, manual operation also poses great safety risks.

[0004] The patent publication number CN216763526U proposes a pilot rhythm variable flow pneumatic ash conveying embolism valve group, including a pneumatic conveying embolism valve. The pneumatic conveying embolism valve includes an air outlet assembly, a rectifying assembly, and an air inlet assembly. When an embolism occurs in the ash conveying pipeline, the residual gas pressure in the ash conveying pipeline rises. The first check head seals the connection between the air outlet chamber and the ash conveying pipeline. The working gas entering the air inlet chamber through the companion gas pipeline enters the driving chamber through the first one-way valve. The driving element drives the valve plug to move, so that a large amount of working gas enters the intermediate chamber. After the working gas is deflected and rectified by the rectifying element, the working gas pushes open the first check head and enters the ash conveying pipeline, giving full play to the pneumatic ash conveying function and eliminating the embolism. In the pneumatic conveying system using the pilot rhythm variable flow pneumatic ash conveying embolism valve group, the air inlet chamber of the pneumatic conveying embolism valve is connected to the companion gas pipeline, and the air outlet chamber of the pneumatic conveying embolism valve is connected to the ash conveying pipeline, improving the reliability of the pneumatic conveying system.

[0005] In view of the above related technologies, the inventor found the following defects:

[0006] 1. The pilot rhythm variable flow pneumatic ash conveying embolism valve monitors the pressure of the ash conveying pipeline by allowing compressed gas to enter the ash conveying pipeline through the pilot valve. When the ash conveying pipeline is not blocked, compressed air will continuously enter the ash conveying pipeline, resulting in waste of compressed air.

[0007] 2. The pilot rhythm variable flow pneumatic ash conveying embolism valve group mainly relies on the rhythmically changing airflow after the working gas is rectified by the rectifying element for cleaning. Its impact force is relatively weak. For some tightly adhered and hard ash deposits, it may not be able to completely remove them like a blasting pulse conveyor. As the use time increases, the influence of the residual ash deposits on the pipeline conveying efficiency will gradually become apparent.

[0008] 3. Although the pilot rhythm variable flow pneumatic ash conveying embolism valve group can increase the gas flow and pressure when the ash conveying pipeline is embolized, this change is relatively gentle and lacks the instantaneous and powerful impact force like a blasting pulse. When dealing with some firm ash deposits formed by material adhesion and chemical reactions, the ash cleaning efficiency is poor.

[0009] 4. Although the pilot rhythm variable flow pneumatic ash conveying embolism valve group has an intake spring, an outlet spring, and one-way valves to control the gas flow direction and pressure, when dealing with complex and changeable ash cleaning scenarios, the accuracy and flexibility of pressure regulation are far less than the former, and it is difficult to accurately adjust the pressure according to the real-time ash cleaning requirements.

[0019] Optionally, the differential pressure valve regulating slider is installed on the differential pressure regulating screw rod. The differential pressure regulating spring is installed between the differential pressure regulating slider and the gasket on the differential pressure valve diaphragm. By rotating the differential pressure regulating knob, the differential pressure regulating screw rod is driven to rotate, thereby driving the differential pressure regulating slider to move up and down to adjust the pre-tightening force of the differential pressure regulating spring and form an elastic linkage structure with the differential pressure valve diaphragm.

[0020] Optionally, pressure gauge assemblies are provided on one side of both the main valve seat body and the differential pressure valve seat body for monitoring the internal air pressure. The main valve seat body and the differential pressure valve seat body are fixedly connected by valve seat bolts. A manual quick exhaust valve, a compressed air source quick connector, and a differential pressure front valve connection quick connector are sequentially arranged on one side of the differential pressure valve seat body. A differential pressure valve rear connection quick connector is provided on one side of the valve cover body.

[0021] Optionally, the main valve upper gasket, the main valve diaphragm, and the main valve lower gasket are connected together by main valve connection rivets. The main valve spring of the main valve assembly is sleeved on one side of the main valve upper gasket to provide the reset elastic force for the main valve diaphragm.

[0022] Optionally, the quick-opening main link and the quick-opening sub-link of the quick-opening mechanism assembly form a telescopic linkage structure through a quick-opening pull spring. The quick-opening link spring is arranged at the bottom of the quick-opening main link body for triggering the quick opening of the main valve assembly.

[0023] Optionally, the pneumatic pressure monitoring piston body of the pulse valve assembly is elastically connected to the T-shaped hole of the differential pressure valve seat body through a pneumatic pressure monitoring piston spring.

[0024] Optionally, a main valve switch quick exhaust valve gasket is fixedly installed at the bottom of the main valve switch quick exhaust valve piston body of the main valve switch quick exhaust valve assembly. The top of the main valve switch quick exhaust valve gasket forms a sealed structure with the inner and outer sealing rings of the main valve switch quick exhaust valve sealing end cover through the main valve switch quick exhaust valve piston rod. The main valve switch quick exhaust valve piston fixing nut is used for limiting and linkage with the quick opening sub-linkage, so as to drive the opening and closing of the main valve switch quick exhaust valve piston body.

[0025] Optionally, the pulse air pipe is communicated with the gas storage cylinder body through a compressed air source quick joint, and the pulsed air flow is sent to the pipeline to be unclogged through the pulse air pipe after being released by the main valve assembly.

[0026] In summary, the present application includes the following beneficial technical effects:

[0027] 1. In the present invention, the opening and closing of the control valve are monitored by the pressure difference in the ash conveying pipelines at both ends of the soot blowing device. When the ash conveying pipeline is normal, no monitored compressed air enters the ash conveying pipe, and there is no waste of compressed air. Moreover, the opening and closing of the blasting pulse conveyor are controlled by the pressure difference, and the work is stable and the precision is high.

[0028] 2. The blasting pulse conveyor uses a strong air flow of suddenly ejected compressed gas to directly rush into the blocked fault area of the conveying pipeline storing the blocked ash material at an ultra-high speed. This suddenly released expansion impact wave overcomes the static friction of the ash material, enabling the ash material in the pipeline to flow again. The clogging removal effect is remarkable.

[0029] 3. When in use, the present invention can quickly act when the triggering condition is met through the linkage structure composed of the quick opening main link body, the quick opening sub-linkage, the quick opening main link top ball bolt, and the main and sub-linkage tension springs, driving the valve diaphragm body to quickly open or close, so that a large amount of pulsed air flow instantly surges into the pipeline, quickly removing stubborn accumulated ash with a powerful impact force, greatly improving the ash cleaning efficiency, shortening the ash cleaning cycle, and reducing the equipment shutdown and maintenance time. Through the combination of components such as the valve cover pressure regulating rod body, the valve cover pressure regulating slider, the valve cover pressure regulating rod O-ring, the valve cover regulating knob body, the valve cover regulating knob end cover, and the valve cover pressure regulating spring, the operator can conveniently manually adjust the internal pressure of the device according to the actual working conditions such as the degree of pipeline ash accumulation and the characteristics of the conveyed material, making the soot blowing force just right, which can not only thoroughly remove the accumulated ash, but also not cause excessive impact on the pipeline, and prolong the service life of the equipment.

[0030] 4. When the present invention is in use, the trumpet-shaped opening of the pressure relief pipe is adapted to the conical air seal block, which can accurately guide the pulsed air flow towards the attachment area of the blocked ash material body, enabling the air flow energy to act concentratedly on the ash accumulation part, avoiding energy dispersion, significantly enhancing the cleaning effect on stubborn ash accumulation, and ensuring the cleanliness of the inner wall of the pipeline. Through the mutual cooperation of the arc-shaped airbag, the air charging pipe, the air inlet pipe, the pressure-bearing seat, the air charging ring and the hose, the elastic deformation of the airbag is used to buffer and regulate the air flow, making the ash cleaning air flow more stable and continuous; the gas transmission network constructed by multiple components ensures that sufficient air source supply can be obtained at each ash cleaning action point, synergistically strengthening the ash cleaning effect and improving the overall ash cleaning efficiency. The first retaining ring and the second retaining ring fix the position of the hose, the rotating pipe and the air pump switch seat facilitate the operator to control the small air pump, and the external thread sleeve, the rotating rod and the bearing ring finely adjust the gas flow rate. These designs enable the operator to easily control the ash cleaning mechanism according to the real-time ash cleaning requirements, adjust the ash cleaning strategy at any time, optimize the ash cleaning process, and adapt to the pipeline ash cleaning tasks under different working conditions.

Detailed implementation manners

[0039] The following will Figure 1-7 further describe the present application in detail with reference to the accompanying

[0040] The embodiment of the present application discloses a pipeline soot blowing device based on a blasting type pulse conveyor.

[0041] Please refer to Figure 1-4, A pipeline sootblowing device based on a blasting pulse conveyor, comprising a main valve seat body 1. A pulse air pipe 4 is connected to the bottom of the main valve seat body 1, and a differential pressure valve seat body 2 is fixedly installed at the top. A valve cover body 3 is fixedly installed at the top of the differential pressure valve seat body 2 through valve cover bolts 10. A gas storage cylinder body 5 is connected to one side of the main valve seat body 1, and one side of the main valve seat body 1 and the differential pressure valve seat body 2 is connected through a pneumatic connection pipe assembly 6. A differential pressure adjustment assembly 8 is arranged at the top of the valve cover body 3;

[0042] The differential pressure adjustment assembly 8 includes a differential pressure adjustment knob 801, a differential pressure adjustment screw rod 802, a screw rod sealing ring 803, a differential pressure adjustment slider 804, a differential pressure adjustment spring 805 and a knob cap 806;

[0043] The differential pressure adjustment knob 801 is installed at the top of the valve cover body 3. The differential pressure adjustment screw rod 802 is connected to the differential pressure adjustment slider 804. The differential pressure adjustment spring 805 is sleeved at the bottom of the differential pressure adjustment slider 804 and is used to adjust the pre-tightening force of the differential pressure valve diaphragm 1501.

[0044] Pressure gauge assemblies 7 are arranged on one side of both the main valve seat body 1 and the differential pressure valve seat body 2 for monitoring the internal air pressure;

[0045] The main valve seat body 1 and the differential pressure valve seat body 2 are fixedly connected through valve seat bolts 9;

[0046] A manual quick exhaust valve 11, a compressed air origin quick connector 12 and a differential pressure front valve connection quick connector 13 are sequentially arranged on one side of the differential pressure valve seat body 2. A differential pressure valve rear connection quick connector 14 is arranged on one side of the valve cover body 3.

[0047] The pulse air pipe 4 and the gas storage cylinder body 5 are connected through the compressed air origin quick connector 12, and the pulsed air flow is delivered to the pipeline to be unclogged through the pulse air pipe 4 after being released by the main valve assembly 17.

[0048] Please refer to Figure 1-5 , The differential pressure valve assembly 15 includes a differential pressure valve diaphragm 1501, a differential pressure valve upper gasket 1502, a differential pressure valve lower gasket 1503 and a differential pressure valve connection rivet 1504. Among them, the differential pressure valve diaphragm 1501 is fixedly installed between the differential pressure valve seat body 2 and the valve cover body 3 and is connected to the differential pressure adjustment assembly 8 through the differential pressure valve connection rivet 1504. The bottom of the differential pressure valve connection rivet 1504 is fixedly connected to the differential pressure adjustment slider 804, and the differential pressure adjustment slider 804 and the differential pressure valve diaphragm 1501 form an elastic linkage structure through the differential pressure adjustment spring 805.

[0049] It should be further explained that: The differential pressure valve assembly 15 is mainly composed of a differential pressure valve diaphragm 1501, a differential pressure valve upper gasket 1502, a differential pressure valve lower gasket 1503, and a differential pressure valve connecting rivet 1504. It plays a key role in pressure regulation and balance in the entire pipeline soot blowing device. The differential pressure valve diaphragm 1501 is fixed between the differential pressure valve seat body 2 and the valve cover body 3, and will deform according to the pressure difference inside and outside the device. When the pressure on both sides is unbalanced, the deformation of the diaphragm will be transmitted to the differential pressure regulating assembly 8 through the differential pressure valve connecting rivet 1504. The upper and lower gaskets of the differential pressure valve ensure the sealing between the diaphragm and surrounding components, prevent gas leakage, and ensure the accuracy of pressure monitoring. The differential pressure regulating assembly 8 can, according to the received signal, adjust the pre-tightening force of the differential pressure valve diaphragm 1501 to restore the internal pressure of the device to balance, creating conditions for the stable generation and transportation of subsequent pulsed airflows.

[0050] Please refer to Figure 1-5 , the quick-opening mechanism assembly 16 includes a quick-opening main connecting rod body 1601, a quick-opening main connecting rod top ball 1602, a quick-opening secondary connecting rod 1603, a quick-opening pull spring 1604, a quick-opening connecting rod spring 1605, a quick-opening mechanism fixing seat body 1606, and a quick-opening mechanism fixing seat bolt 1607. It is fixed inside the differential pressure valve seat body 2 through the quick-opening mechanism fixing seat bolt 1607; the quick-opening main connecting rod body 1601 of the quick-opening mechanism assembly 16 and the quick-opening secondary connecting rod 1603 form a telescopic linkage structure through the quick-opening pull spring 1604. The quick-opening connecting rod spring 1605 is arranged at the bottom of the quick-opening main connecting rod body 1601 and is used to trigger the quick opening of the main valve switch quick exhaust valve assembly 18.

[0051] It should be further explained that: The quick-opening mechanism assembly 16 can achieve a quick-opening action within a short time.

The quick-opening main connecting rod body 1601 and the quick-opening secondary connecting rod 1603 form a telescopic linkage structure through the quick-opening pull spring 1604. This structure enables them to quickly adjust their positions according to air pressure changes. When the air pressure reaches a certain threshold, the quick-opening connecting rod spring 1605 releases energy to trigger the quick opening of the main valve switch quick exhaust valve assembly 18. The quick-opening main connecting rod top ball 1602 ensures the accuracy of force transmission and the reliability of the entire quick-opening process.

[0053] It should be further explained that: the main valve assembly 17 is the core component that controls the air flow from the gas cylinder body 5 to the pulse air pipe 4. It includes a main valve diaphragm 1701, a main valve upper gasket 1702, a main valve lower gasket 1703, a main valve connecting rivet 1704 and a main valve spring 1705. The main valve diaphragm 1701 is installed between the main valve seat body 1 and the differential pressure valve seat body 2 and functions as a switch. When the main valve diaphragm 1701 is opened, the compressed air in the gas cylinder body 5 can smoothly pass through and enter the pulse air pipe 4; when the main valve diaphragm 1701 is closed, the air flow channel is blocked. The main valve upper gasket 1702 and the main valve lower gasket 1703 ensure the sealing performance of the main valve diaphragm 1701 and prevent air leakage.

The pneumatic pressure monitoring piston body 1901 of the pulse valve assembly 19 is elastically connected to the T-shaped hole of the differential pressure valve seat body 2 through the pneumatic pressure monitoring piston spring 1902. The pulse control valve plate body 1907 is linked with the main valve upper gasket 1702 through the pulse control valve plate spring piece body 1908 to control the pulse opening and closing of the main valve assembly 17. The top of the pulse control valve rod body 1905 is connected to the differential pressure valve seat body 2 through the pulse control valve rod spring 1906, and the bottom forms a dynamic seal with the pulse control valve plate body 1907 through the pulse control valve sealing ring 1910.

[0057] It should be further explained that: The pulse valve assembly 19 is a key component for generating pulsed airflows. It can deliver the airflows to the pipeline to be unclogged in the form of pulses, enhancing the soot blowing effect. This assembly includes a pneumatic pressure monitoring piston body 1901, a pneumatic pressure monitoring piston spring 1902, a pneumatic pressure monitoring piston adjusting end cover 1903, a pneumatic pressure monitoring piston sealing ring 1904, a pulse control valve rod body 1905, a pulse control valve rod spring 1906, a pulse control valve disc body 1907, a pulse control valve disc spring body 1908, a pulse control valve disc spring fixing bolt 1909, and a pulse control valve sealing ring 1910. The pneumatic pressure monitoring piston body 1901 is elastically connected to the T-shaped hole of the differential pressure valve seat body 2 through the pneumatic pressure monitoring piston spring 1902 to monitor the pneumatic pressure changes in real time. When the pneumatic pressure reaches the set value, the pneumatic pressure monitoring piston body 1901 moves, driving the movement of the pulse control valve rod body 1905. The pulse control valve rod body 1905 is connected to the differential pressure valve seat body 2 through the pulse control valve rod spring 1906, and its bottom forms a dynamic seal with the pulse control valve disc body 1907 through the pulse control valve sealing ring 1910. The pulse control valve disc body 1907 is linked with the main valve upper gasket 1702 through the pulse control valve disc spring body 1908, controlling the pulse opening and closing of the main valve assembly 17 according to the pneumatic pressure changes, thereby generating pulsed airflows and effectively blowing and unclogging the pipeline.

[0058] The implementation principle of the pipeline soot blowing device based on the blasting type pulse conveyor in the embodiment of the present application is as follows:

[0059] First, before the device starts to operate, the gas storage cylinder body 5 pre-stores compressed air to provide a stable gas source for the main valve seat body 1. The pressure gauge assembly 7 on one side of the main valve seat body 1 and the differential pressure valve seat body 2 monitors the internal pneumatic pressure in real time to ensure that the pneumatic pressure is within the normal working range. The operator can judge whether the initial state of the device meets the requirements by observing the pressure gauge value. At the same time, the differential pressure adjustment assembly 8 can, according to actual needs, rotate the differential pressure adjustment knob 801 to adjust the positions of the differential pressure adjustment screw rod 802 and the differential pressure adjustment slider 804, changing the pre-tightening force of the differential pressure valve diaphragm 1501 and setting the pneumatic pressure difference threshold for the device to trigger an action.

[0060] Second, when the compressed air in the gas storage cylinder body 5 continues to be input into the main valve seat body 1, the pneumatic pressure between the main valve seat body 1 and the differential pressure valve seat body 2 gradually changes. The differential pressure valve diaphragm 1501 in the differential pressure valve assembly 15 keenly senses this change in the pneumatic pressure difference. Since it is fixedly installed between the differential pressure valve seat body 2 and the valve cover body 3, the pneumatic pressure difference will cause the diaphragm to deform, and through the differential pressure valve connecting rivet 1504, this deformation is transmitted to the differential pressure adjustment slider 804 in the differential pressure adjustment assembly 8, thereby triggering subsequent mechanical actions.

[0061] Next, as the pressure difference further increases and reaches the trigger threshold of the quick-opening mechanism assembly 16, the quick-opening mechanism starts to work. The telescopic linkage structure formed by the quick-opening main connecting rod body 1601 and the quick-opening sub-connecting rod 1603 through the quick-opening tension spring 1604 responds quickly. The quick-opening connecting rod spring 1605 releases energy to push the quick-opening main connecting rod body 1601 to move. The quick-opening main connecting rod top ball 1602 ensures the accuracy of force transmission. The action of the quick-opening mechanism is transmitted to the main valve switch quick exhaust valve assembly 18 through the main valve switch quick exhaust valve piston fixing nut 1807.

[0062] Next, triggered by the quick-opening mechanism, the main valve switch quick exhaust valve piston body 1801 of the main valve switch quick exhaust valve assembly 18 overcomes the elastic force of the main valve switch quick exhaust valve spring 1803 and moves upward in the valve cylinder cavity of the differential pressure valve seat body 2. The main valve switch quick exhaust valve gasket 1802 at the bottom of the main valve switch quick exhaust valve piston body 1801 leaves the exhaust hole in the differential pressure valve seat body 2, opening the exhaust passage to achieve rapid gas discharge. At the same time, the main valve diaphragm 1701 in the main valve assembly 17 is opened under the influence of the air pressure change and the action of the quick exhaust valve, overcoming the elastic force of the main valve spring 1705. At this time, the compressed air in the gas storage cylinder body 5 enters the pulse air pipe 4 through the main valve seat body 1.

[0063] Finally, the pulse valve assembly 19 plays a key role in the whole process to generate pulsed air flow. The air pressure monitoring piston body 1901 is elastically connected in the T-shaped hole of the differential pressure valve seat body 2 through the air pressure monitoring piston spring 1902 to monitor the air pressure change in real time. When the air pressure changes, the air pressure monitoring piston body 1901 moves, driving the pulse control valve rod body 1905 to move. The pulse control valve rod body 1905 is connected to the differential pressure valve seat body 2 through the pulse control valve rod spring 1906. Its bottom forms a dynamic seal with the pulse control valve plate body 1907 through the pulse control valve seal ring 1910. The pulse control valve plate body 1907 is linked with the main valve upper gasket 1702 through the pulse control valve plate spring piece body 1908 and opens and closes continuously according to the air pressure change, so that the air flow entering the pulse air pipe 4 is transported to the pipeline to be unblocked in a pulsed form, realizing effective soot blowing and blockage removal of the pipeline. When the air pressure returns to a certain level, each component returns to the initial state under the action of the spring, waiting for the next working cycle.

[0064] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
