Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of pipeline safety, and particularly relates to an intelligent self-cleaning flame arrester device. BACKGROUND

[0002] The flame arrester is an important industrial safety device, and its core function is to prevent the spread of fire in the pipeline or equipment while allowing gas or liquid to pass through, thereby preventing the expansion of fire or explosion accidents. During use, rust, dust, coking and other impurities in the pipeline will adhere to the narrow passage of the flame arrester core, causing blockage. Especially in cold environments or high humidity, water condenses on the flame arrester core and mixes with dust to form a muddy substance, which can exacerbate the blockage. In coal mine gas conveying pipelines, once the flame arrester is blocked, it will cause multiple problems such as reduced conveying efficiency due to gas flow obstruction, control failure due to negative pressure system disorder, and flame arrester failure. The traditional method for dealing with the blockage of the flame arrester mainly relies on regular manual inspection and disassembly and cleaning. The commonly used cleaning method is to add a standby flame arrester in the pipeline. After the standby route is enabled, the blocked flame arrester is disassembled and manually cleaned. This method is time-consuming and labor-intensive, and has low efficiency and high cost. Moreover, there is a safety hazard due to the failure to clean in time. Therefore, the flame arrester device with online blockage detection and automatic cleaning functions has attracted more and more attention.

[0003] Chinese Patent Application CN107842389A discloses a gas extraction flame arrester with self-cleaning function, which includes a flame arrester core, a differential pressure monitoring device and a cleaning device. The differential pressure monitoring device is used to detect the pressure difference on both sides of the flame arrester core to determine the degree of blockage of the flame arrester core. When the pressure difference exceeds the preset value, the cleaning device will be triggered to clean the flame arrester core, thereby reducing manual intervention and improving cleaning efficiency and safety. However, in the above-mentioned prior art solution, the flame arrester core directly deals with impurities in the gas pipeline. In gas pipelines with high dust content and humidity in coal mines and the like, the flame arrester core may be blocked frequently, which may trigger the cleaning device excessively frequently and disrupt production continuity. Therefore, this solution is only suitable for scenes with relatively low impurity content. On the other hand, the prior art solution uses a water spraying mechanism to clean the flame arrester core. The nozzle of the water outlet faces the flame arrester core and sprays water for flushing. However, it is actually difficult to clean the flame arrester completely through single-angle and one-way water flushing. In particular, oil stains and the like that block the flame arrester core are not easy to fall off, resulting in poor cleaning effect and affecting the performance recovery of the flame arrester core. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application aims to provide an intelligent self-cleaning flame arrester device. The impurity pre-separation technology is used to reduce the blockage frequency of the flame arrester core and improve production continuity. At the same time, the full-coverage cleaning of the end surface of the flame arrester core and the heating treatment of the pipeline gas are adopted to improve the cleaning efficiency and effect and ensure the performance recovery of the flame arrester core.

[0006] Preferably, the cleaning device mounting bracket is fixed to the inner wall of the cavity of the flame arrester device, the cleaning device connecting base is a hollow structure, the right end is connected with the cleaning connecting pipeline, and the left end is connected with the nozzle seat through double sealing rings.

[0007] Preferably, the cyclone separator has a conical structure that is larger at the top and smaller at the bottom, including a cyclone separator inlet pipe, a cyclone separator outlet pipe, a cyclone separator housing, a cyclone separator slag discharge pipe, and a cyclone separator solenoid valve. The cyclone separator inlet pipe, the cyclone separator outlet pipe, and the cyclone separator slag discharge pipe are respectively installed at the left end, the upper end, and the lower end of the cyclone separator housing. The cyclone separator inlet pipe is connected to the left-side gas delivery pipeline. The cyclone separator achieves the initial separation of impurities in the gas pipeline.

[0008] Preferably, the flame-arresting air inlet is connected to the cyclone separator outlet pipe at the left end of the flame-arresting device, a flame-arresting slag discharge pipe is installed at the lower part of the flame-arresting air inlet, and the flame-arresting air outlet is connected to the right-side conveying gas pipeline at the right end of the flame-arresting device.

[0010] Preferably, the main body of the flame-arresting air inlet and flame-arresting air outlet is cylindrical, and the front and rear ends are tapered, which is conducive to stable gas flow and reduces airflow resistance.

[0011] Preferably, the solid-liquid separation tank body adopts an inclined structure, the solid-liquid drain outlet is located on the lower part of the lower side of the solid-liquid separation tank body, the solid-liquid slag discharge outlet is located on the lower part of the higher side of the solid-liquid separation tank body, and the filter screen is installed inclined inside the solid-liquid separation tank body.

[0012] Preferably, the intelligent cleaning system further includes a heating module, which is connected to the controller via a line and installed on the cleaning connection pipeline. When the heating module is turned on, the oil, impurities, etc. that are blocking the flame arrestor core can be more easily removed, and the pipeline gas can also be dehydrated and dried.

[0013] The working principle of this technical solution is as follows: Cyclone separator: After the gas enters, it rotates. Under the action of airflow and gravity, large solid and liquid particles accumulate downward along the inner wall of the box and at the slag discharge port. The solenoid valve opens at timed intervals to discharge slag, and the external swirling airflow turns upward and is discharged from the gas outlet pipe, realizing the initial separation of impurities. Flame arrestor: Gas enters through the inlet and passes through the flame arrestor core. Its tiny orifices are easily blocked by small impurities, which will increase the pressure difference on both sides of the flame arrestor core. Solid-liquid separation device: It receives slag through a connecting pipe, the box is tilted, and there is a filter screen inside to perform simple separation of solid and liquid. Water is discharged from the drain outlet, and solid slag is discharged from the slag outlet. Working principle of the intelligent cleaning system: Front and rear pressure probes are installed at both ends of the flame arrester, and the controller monitors the pressure difference between the two ends. If the pressure difference exceeds the preset safety threshold, the controller controls the intelligent cleaning solenoid valve and the solenoid valve on the slag discharge pipe of the flame arrester to open. The high-pressure air or water provided by the power source (high-pressure air circuit, water circuit or temporary high-pressure tank) is sprayed out through the pipeline and nozzle. The nozzle seat rotates under reverse pressure to improve the reverse flushing efficiency. When drying is required, the heating module is turned on to help impurities fall off and dry the gas. When the pressure difference between the two ends of the flame arrester stabilizes, the controller controls the solenoid valve to close, and the cleaning system is shut down.

[0014] The beneficial effects obtained by adopting the above technical solution are as follows: (1) The present invention introduces a cyclone separator, which can change the incoming gas from linear motion to rotational motion. Under the combined action of airflow and gravity, large solid and liquid particles move downward along the inner wall of the separator and eventually accumulate at the slag discharge port, realizing the initial separation of impurities in the gas pipeline. The removal of large particles of impurities in advance can reduce the burden on the flame arrestor and reduce the frequency of cleaning the flame arrestor core. (2) The intelligent cleaning system is based on the principle of high-pressure air or water jet technology. It adopts a multi-angle nozzle mounting hole and nozzle seat rotation design. The existing underground compressed air or water supply system pressurizes the air or water. The high-pressure air or water is sprayed out through nozzles at different angles. The nozzle seat rotates under the reverse pressure of the nozzle, which improves the reverse flushing efficiency, realizes full coverage cleaning of the flame arrestor core end face, reduces cleaning dead angles, and improves cleaning efficiency and effect. (3) The intelligent cleaning system has added a heating module. In addition to high-pressure gas reverse cleaning, the heating module in the pipeline can also be turned on at the same time. On the one hand, it makes it easier for oil stains and impurities that block the flame arrestor core to fall off. On the other hand, it can also dehydrate and dry the gas in the pipeline, reducing the blockage caused by moisture condensing on the flame arrestor core and mixing with dust to form mud.

[0022] The cyclone separator 1 includes a cyclone separator inlet pipe 11, a cyclone separator outlet pipe 12, a cyclone separator housing 13, a cyclone separator slag discharge pipe 14, and a cyclone separator solenoid valve 15. The cyclone separator housing 13 has the cyclone separator inlet pipe 11 installed at the left end, the cyclone separator outlet pipe 12 installed at the upper end, and the cyclone separator slag discharge pipe 14 installed at the lower end. The cyclone separator inlet pipe 11 is connected to the left-side gas delivery pipeline. The cyclone separator outlet pipe 12 is connected to the left end of the flame arrestor 2.

[0023] The flame arresting device 2 is a hollow cavity, including a flame arresting air inlet 21, a flame arresting air outlet 22, and a flame arresting core 23.

A flame arresting slag discharge pipe 213 is installed at the lower part of the flame arresting air inlet 21. The flame arresting slag discharge pipe 213 is sealed to the upper part of the solid-liquid separation device 3 through flanges, gaskets, bolts, and nuts. The flame arresting air outlet 22 is connected to the right-side delivery air pipe at the right end of the flame arresting device 2. The gas flow is connected via flanges. The main body of the flame-arresting inlet end 21 and the flame-arresting outlet end 22 is cylindrical, with tapered structures at both ends, which facilitates stable gas flow and reduces airflow resistance. The flame-arresting inlet end 21 and the flame-arresting outlet end 22 are externally fastened together with bolts, washers, and nuts, and internally sealed together with sealing gaskets 211 and sealing rings 212. The flame-arresting core 23 is installed in the middle of the cavity of the flame-arresting device 2, and the flame-arresting core is self-fixed according to the structural dimensions of the flame-arresting device 2. Figure 2 As shown, the flame-arresting core 23 includes a flame-arresting core frame 231 and a flame-arresting core body 232, with the flame-arresting core body 232 installed inside the flame-arresting core frame 231.

The cyclone separation connecting pipe 31 and the flame arrestor connecting pipe 32 are connected to the cyclone separation slag discharge pipe 14 and the flame arrestor slag discharge pipe 213 respectively at the upper end of the solid-liquid separation device 3 via flanges. A cyclone separation solenoid valve 311 and a flame arrestor solenoid valve 321 are respectively installed on the cyclone separation connecting pipe 31 and the flame arrestor connecting pipe 32. The solid-liquid separation tank 33 has an inclined structure, with the solid-liquid drain outlet 34 on the lower part of the lower side and the solid-liquid slag discharge outlet 35 on the lower part of the upper side. An inclined filter screen 36 is installed inside. The solid-liquid separation device performs simple separation of the solid and liquid discharged into the solid-liquid separation tank 33 by the cyclone separation connecting pipe 31 and the flame arrestor connecting pipe 32.

[0025] The intelligent cleaning system 4 includes a front-end pressure probe 41, a rear-end pressure probe 42, a controller 43, an intelligent cleaning solenoid valve 45, a cleaning device 46, and a cleaning connection pipeline 47. The front-end pressure probe 41 is installed at the flame arrestor air inlet 21, and the rear-end pressure probe 42 is installed at the flame arrestor air outlet 22. The front-end pressure probe 41 and the rear-end pressure probe 42 are connected to the controller 43 via power lines and data lines. The controller 43 is connected to the intelligent cleaning solenoid valve 45 and the flame arrestor solenoid valve 321 via wiring. The intelligent cleaning solenoid valve 45 is installed on the cleaning connection pipeline 47. The cleaning device 46 is installed inside the flame arrestor device 2 cavity and is located within the flame arrestor core 23. On the right side, the upper end of the cleaning connection pipe 47 is connected to the power source, and the lower end of the cleaning connection pipe 47 extends into the internal cavity of the flame arrester 2 through the sealing connection sleeve 221 and is connected to the cleaning device 46. The above-mentioned intelligent cleaning system can use a high-pressure gas line, water line or temporary high-pressure tank as a power source for cleaning according to actual needs. The intelligent cleaning system 4 also includes a heating module 44, which is connected to the controller 43 through a line. The heating module 44 is installed on the cleaning connection pipe 47. Therefore, in addition to using high-pressure fluid reverse cleaning, the heating module 44 in the pipe can also be turned on simultaneously, making it easier for oil stains and impurities blocking the flame arrester core to fall off, and can also dehydrate and dry the gas in the pipe.

[0026] like Figure 3 As shown, the cleaning device 46 includes a cleaning device mounting bracket 461, a cleaning device bearing 462, a cleaning device connecting base 463, a nozzle seat 464, and a nozzle 465. The cleaning device mounting bracket 461 is fixed to the inner surface of the cavity of the flame arrestor 2. The cleaning device connecting base 463 has a hollow structure, with its right end connected to the cleaning connection pipe 47 and its left end slidably sealed to the nozzle seat 464 via double sealing rings 466. The cleaning device bearing 462 is mounted on... Between the nozzle seat 464 and the cleaning device mounting bracket 461, the nozzle seat 464 is a hollow structure, and the left end of the nozzle seat 464 is a conical structure with nozzle mounting holes at different angles. The nozzle 465 is installed on the mounting holes of the nozzle seat 464. The cleaning device pressurizes air or water through the underground compressed air or water supply system and ejects it through the nozzle at the end of the pipeline to clean and unblock the flame arrestor core. By using different nozzle mounting angles and the rotation of the nozzle seat, full coverage of the flame arrestor core end face cleaning can be achieved.

[0027] The working process of the above-mentioned intelligent self-cleaning flame arrester device is as follows: The gas containing impurities, transported in the pipeline, first enters the cyclone separator, where its linear motion changes to rotational motion. Under the combined action of airflow and gravity, large solid-liquid particles move downwards along the inner wall of the separator, eventually accumulating at the discharge port. The solenoid valve opens and closes according to a set timer, discharging the waste residue into the solid-liquid separator. The downward swirling airflow turns upwards near the conical bottom of the separator, ultimately exiting through the exhaust pipe at the top of the separator, achieving initial separation.

[0028] The discharged gas continues to flow after passing through the flame arrestor. Due to the characteristics of the flame arrestor core, its internal fine pores are easily clogged by small impurities carried in the gas. As the degree of clogging increases, the pressure difference across the flame arrestor core also increases. Through pressure probes installed on both sides of the flame arrestor core, when the pressure difference exceeds a preset safety threshold, the valves at the connection between the flame arrestor's inlet and the left gas pipeline, and at the connection between the outlet and the right gas pipeline, are closed. The intelligent cleaning system is activated, and the controller simultaneously opens the intelligent cleaning solenoid valve and the flame arrestor's slag discharge pipe solenoid valve. High-pressure gas or water flows through the pipeline and is sprayed out through nozzles at different angles to clean the flame arrestor core. The nozzle seat rotates under the reverse pressure of the nozzle, improving the efficiency of reverse rinsing the flame arrestor core. In addition to high-pressure gas reverse cleaning, the heating module in the pipeline can also be activated simultaneously. This makes it easier for oil and impurities clogging the flame arrestor core to fall off, and also dehydrates and dries the gas in the pipeline.

[0029] Under high-pressure gas or hydraulic pressure, impurities and particles clogging the flame arrestor core are discharged into the solid-liquid separation device through the slag discharge pipe at the inlet of the flame arrestor. An inclined filter screen installed in the separation chamber separates the water and slag. Water is discharged through the drain outlet along the inclined surface at the bottom of the chamber, while solid slag is discharged through the slag discharge outlet via the inclined filter screen. When the pressure on both sides of the flame arrestor core stabilizes, the controller controls the solenoid valve, shutting off the intelligent cleaning system and restoring normal gas delivery. To ensure overall pipeline delivery efficiency, the operating time of the intelligent cleaning system can be set as required, but should not be too long.
