Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, specifically to an acetylene component detection device for a calcium carbide dust collector. Background Technology

[0002] Carbide crushing dust collectors are installed outdoors, and long-term use can lead to problems such as corrosion of the sealing plates, rainwater ingress, the inhalation of moisture, and condensation on the inner walls due to temperature differences. The carbide crushing process generates a large amount of dust, which is collected by the dust collector. However, when the dust collector becomes damp, increasing the ambient humidity, or when rainwater enters, the carbide powder inside reacts with the moisture to produce acetylene gas. The accumulation of acetylene gas inside the dust collector poses a potential explosion risk. Therefore, it is urgent to address how to prevent safety accidents caused by the accumulation of this flammable and explosive gas inside the dust collector. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An acetylene component detection device for a calcium carbide dust collector includes a sampling mechanism and an analysis mechanism connected to the sampling mechanism. The sampling mechanism includes a sampling pipeline and a sampling system. One end of the sampling pipeline is installed on the outlet flue of the calcium carbide dust collector, and the other end is connected to the sampling system.

The inlet of the gas delivery pipe is connected to the inert gas booster pump, and the outlet is installed on the outlet flue of the calcium carbide dust collector. The one-way sealing component is disposed at the end of the outlet and can seal or open the outlet. The inert gas booster pump is communicatively connected to the analysis and detection device.

[0006] A further technical solution is that the one-way sealing assembly includes a base, a spring, and a sealing plug. The base is sleeved on the inner wall of the gas supply pipe and fixedly connected to the inner wall of the gas supply pipe. The base is circular in shape. One end of the spring is connected to the base, and the other end extends toward the gas outlet and is connected to the sealing plug. The sealing plug has a trapezoidal cross-section, and an installation cylinder is installed at the end of the gas outlet. The installation cylinder is adapted to the sealing plug.

[0007] A further technical solution is that the sampling pipeline includes a sampling probe and a sampling line, with the sampling probe inserted into the front end of the sampling line; the sampling system includes a sampling pump, a ball valve, and a sampling valve, with the end of the sampling line connected to the sampling pump via a pipe, the ball valve mounted on the pipe, and the sampling valve installed on the sampling line.

[0012] The acetylene component detection device for the calcium carbide dust collector provided in this embodiment, through gas sampling, processing, analysis, and emission, combined with intelligent analysis and detection equipment, can monitor and control the acetylene gas concentration inside the calcium carbide dust collector in real time. When the acetylene gas concentration inside the dust collector exceeds the normal range, the analysis and detection equipment controls the inert gas booster pump to start and transmit inert gas to the gas delivery pipe. The inert gas pushes the one-way sealing component at the end of the gas delivery pipe to open the gas outlet, allowing the inert gas to reach the dust collector outlet flue to dilute the acetylene, thereby reducing the acetylene gas concentration inside the dust collector outlet flue. This effectively prevents explosion accidents caused by acetylene accumulation, reduces safety hazards caused by rain or increased environmental humidity, and ensures the safety and environmental protection of the dust collector.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Example 1

[0019] This embodiment provides an acetylene component detection device for a calcium carbide dust collector, including a sampling mechanism and an analysis mechanism connected to the sampling mechanism. The sampling mechanism includes a sampling pipeline 12 and a sampling system 11. One end of the sampling pipeline 12 is installed on the outlet flue of the calcium carbide dust collector, and the other end is connected to the sampling system 11. The analysis mechanism includes a cabinet 21 and a processing system 22, an analysis and detection device 23, an emission system 24, and a dilution system disposed within the cabinet 21. The processing system 22 is connected to the sampling system 11, and the processing system 22 is also connected to the analysis and detection device 23. The analysis and detection device 23 is also connected to the emission system 24. The dilution system includes an inert gas booster pump 25, a one-way sealing assembly, and a gas delivery pipe 26. One end of the gas delivery pipe 26 is connected to the inert gas booster pump 25, and the other end is installed on the outlet flue of the calcium carbide dust collector. The one-way sealing assembly is disposed inside the gas delivery pipe 26. The inert gas booster pump 25 is communicatively connected to the analysis and detection device 23.

[0020] In this embodiment, the analysis unit in the acetylene component detection device of the calcium carbide dust collector is directly installed inside the analysis cabinet. The cabinet 21 is made of heat-insulating and ventilated materials, such as a brick-built analysis chamber or a polystyrene color steel plate structure, so that the cabinet 21 has the characteristics of heat insulation, lighting and ventilation, allowing the analysis unit to work stably and safely inside the analysis cabinet; the distance between the sampling mechanism and the analysis unit should be less than 50 meters, the closer the distance between the sampling mechanism and the analysis unit, the more accurate the analysis; the sampling system 11 includes a sampling pump, a ball valve and a sampling valve, and the sampling pipeline 1 2. Includes a sampling probe and a sampling pipeline; the sampling pipeline is made of stainless steel of at least 316 grade and is externally wrapped with a temperature-controlled heat tracing pipeline or heating tape. The temperature-controlled heat tracing pipeline or heating tape is connected to the power supply via a dedicated connecting wire or terminal block. Insulation material is also used to wrap the temperature-controlled heat tracing pipeline or heating tape with the sampling pipeline to ensure heat tracing effect. If the sampling pipeline consists of multiple sections, they can be connected together by welding or flanges. The sampling probe is installed inside the outlet flue of the calcium carbide dust collector to collect gas samples from the flue. The sampling probe is an in-line pluggable probe with a pre-filter, made of stainless steel, which effectively filters dust and prevents clogging. The probe is inserted into the front end of the sampling line, and the connection is sealed using seals (e.g., gaskets) and fasteners (e.g., nuts). The filter portion of the sampling probe is located at the inlet of the sampling line to filter the collected sample gas. The end of the sampling line is connected to the inlet of the sampling pump in the sampling system 11 via a pipe (e.g., a DN40 pipe). A ball valve in the sampling system 11 is installed on the pipe between the sampling line and the sampling pump. The sampling system is used to control the flow of sample gas. All pipeline connections are paired flanges, and gaskets are installed between the flanges. The flanges are tightened with fasteners (such as bolts and nuts) to ensure the sealing and reliability of the connection. The sampling valve in the sampling system 11 is installed on the sampling pipeline through pipes and fasteners. A tag nameplate is fixedly installed on the surface of the sampling valve or the sampling pipeline to identify the number or name of the sampling point. The sampling mechanism starts sampling. The sampling probe collects sample gas at the outlet flue of the dust collector. The sample gas then enters the sampling pump through the sampling pipeline and the DN40 pipe to complete the sampling.

[0021] Furthermore, the sampling pump is connected to the pretreatment equipment of the processing system 22 in the analysis cabinet via a pipeline. The pretreatment equipment includes a dust collector, a condenser, and a filter. The sample gas in the sampling pump enters the dust collector, condenser, and filter sequentially through the pipeline, so that the dust collector, condenser, and filter can sequentially perform dust removal, dehumidification, and filtration treatment on the sample gas. Through the combination of pretreatment equipment, dust, moisture, and impurities in the sample gas can be effectively removed, ensuring that the sample gas reaches an ideal clean and dry state before entering the analysis and detection equipment 23. For the discharge of condensate from the condenser, a condensate drain device is connected to the condenser, such as a peristaltic pump, to discharge the condensate and prevent condensate accumulation. After the filter treatment is completed, the pretreated sample gas enters the analysis and detection equipment 23 through a pipeline. A flow stabilization device, such as a flow stabilizing valve, is installed on the pipeline between the filter and the analysis and detection equipment 23 to ensure that the pretreated sample gas can enter the analysis and detection equipment 23 with a stable flow rate.

[0022] Furthermore, the pretreated sample gas enters the analysis and detection equipment 23 through a pipeline. The analysis and detection equipment 23 can be a specially purchased device capable of automatic control, detection, data processing, and storage, such as using intelligent instruments. The analysis and detection equipment 23 is initially housed within an explosion-proof enclosure, the explosion-proof rating of which is selected based on environmental requirements. The analysis and detection equipment 23 includes a central control system, a detector, and an alarm. The central control system communicates with the inert gas booster pump 25 via a communication protocol, such as Modbus, allowing the central control system to control the pump's on / off operation. The control processing module, data storage module, communication module, and user interaction module within the central control system are respectively connected to these modules. The detector, based on the acetylene medium detection principle, uses infrared or laser detection to detect whether the pretreated sample gas contains acetylene gas and to determine its concentration. The detector is connected to a gas calibration system to obtain accurate results. After obtaining the results, the detector sends them to the control processing module. The control processing module processes the data and determines whether the acetylene concentration exceeds the standard. The control processing module then sends the results to the data storage module for storage. It also sends the results to the communication module, which then transmits them to external devices, such as the operator's monitoring phone, so that the operator can receive the results promptly. When the control processing module determines that the acetylene concentration exceeds the standard, it sends a command to the inert gas booster pump 25 in the dilution system to activate it. This allows the inert gas booster pump 25 to deliver inert gas to the dust collector's outlet flue to dilute the acetylene concentration in the flue. It also sends an alarm command to the alarm device, which sends an alarm message. Simultaneously, it sends the exceedance information to the operator's monitoring phone via the communication module, allowing the operator to see the exceedance information promptly.

[0023] Furthermore, for the dilution system, when the analysis and detection device 23 detects that the acetylene gas concentration in the collected sample gas exceeds the standard, it will control the inert gas booster pump 25 to start, and the gas delivery pipe 26 will deliver inert gas. When the inert gas does not reach the outlet of the gas delivery pipe 26, the one-way sealing component seals the outlet; when the inert gas reaches the outlet end of the gas delivery pipe 26, due to the inconsistent gas pressure on both sides of the one-way sealing component, the inert gas will squeeze the one-way sealing component, causing the one-way sealing component to open the outlet, thereby allowing the inert gas to reach the outlet flue of the dust collector and dilute the acetylene gas in the flue.

[0024] In one embodiment, the one-way sealing assembly includes a base 271, a spring 272, and a sealing plug 273. The base 271 is an annular base 271 fitted onto the inner wall of the gas supply pipe 26 near the outlet. The base 271 is fixedly connected to the inner wall of the gas supply pipe 26 by bolts. One end of the spring 272 is connected to the base 271, and the other end extends along the length of the gas supply pipe 26 and toward the outlet. The other end of the spring 272 is connected to the sealing plug 273, which is a rubber sealing plug with a trapezoidal cross-section. An installation cylinder 261 is fixedly installed at the outlet end of the gas supply pipe 26 by bolts. The shape and size of the installation cylinder 261 are adapted to the rubber sealing plug, meaning the rubber sealing plug can seal the installation cylinder 261. When the inert gas booster pump 25 is not turned on, there is no inert gas in the gas supply pipe 26, the rubber sealing plug seals the installation cylinder 261, and the spring 272 is naturally stationary. In the off state, the outlet of the gas supply pipe 26 is closed. When the central control system of the analysis and detection equipment 23 controls the inert gas booster pump 25 to open, the gas supply pipe 26 transmits inert gas, and the inert gas is pressurized. When the inert gas reaches the one-way sealing component, the pressurized inert gas contacts the rubber sealing plug through the annular base 271 and the spring 272 and pushes the rubber sealing plug away from the mounting cylinder 261. At this time, the spring 272 is stretched, the rubber sealing plug leaves the mounting cylinder 261, and the outlet of the gas supply pipe 26 opens. Thus, the inert gas reaches the outlet flue of the dust collector to dilute the acetylene gas. After the central control system controls the inert gas booster pump 25 to close, the gas supply pipe 26 no longer transmits inert gas. When the spring 272 returns to its natural static state, it will drive the rubber sealing plug to move to the sealing mounting cylinder 261. At this time, the outlet of the gas supply pipe 26 closes again to prevent impurities in the outlet flue of the dust collector from entering the gas supply pipe 26 and contaminating the gas supply pipe 26.

[0025] Furthermore, the inert gas booster pump 25 stores nitrogen gas, which is delivered to the outlet flue of the dust collector through the gas delivery pipe 26. This is to dilute the acetylene gas in the flue with nitrogen gas and prevent an explosion due to excessive acetylene.

[0026] Furthermore, after the analysis and detection equipment 23 completes the analysis and detection of the sample gas, the analysis and detection equipment 23 transports the sample gas to the emission system 24 through the pipeline. The emission system 24 processes the sample gas, for example, by diluting the sample gas, and then discharges the sample gas. In addition, the emission system 24 can also discharge the drainage in the treatment system 22 to prevent liquid accumulation.

[0027] The acetylene component detection device for a calcium carbide dust collector provided in this embodiment has a one-way sealing assembly consisting of a sealing plug 273, a spring 272, and a base 271 installed on the outlet of the gas supply pipe 26. The sealing plug 273 can seal or open the outlet of the gas supply pipe 26 during the reciprocating motion of the spring 272. Thus, when the gas supply pipe 26 is supplying nitrogen, the sealing plug 273 moves away from the mounting cylinder 261 at the outlet, the outlet opens, and nitrogen enters the outlet flue to dilute the acetylene gas. When the gas supply pipe 26 is not supplying nitrogen... The outlet is sealed by the sealing plug 273 due to the return motion of the spring 272, preventing impurities in the outlet flue from entering the gas supply pipe 26, thus protecting the inside of the gas supply pipe 26. Furthermore, the device can continuously monitor the acetylene gas concentration in the dust collector outlet flue, promptly detect concentration exceeding the standard, and effectively prevent explosion accidents caused by acetylene accumulation in the dust collector outlet flue due to rain or humid environment through real-time monitoring and automatic alarm functions. The use of intelligent instruments and automated control system improves monitoring efficiency and accuracy.
