[0024] This disclosure aims to address the problem that existing marine dry pulping processes typically lack a systematic dust concentration detection device, making it impossible to monitor dust concentration in real time and ensuring a safe operating environment. This can lead to equipment damage, health hazards, and even dust explosions in severe cases. Therefore, this disclosure proposes a dust concentration detection device for marine dry pulping. By incorporating a novel dust concentration detection device, utilizing a light scattering sensor and intelligent data processing technology, it achieves real-time monitoring and safety management of dust concentration during the marine pulping process. Through integration with ventilation and dust removal equipment and an explosion-proof design, this device effectively prevents dust hazards, ensures the safe operation of the pulping production line, and adapts to the special requirements of the marine environment.

[0025] like Figures 1 to 5 As shown, a dust concentration detection device based on marine dry pulping includes a dust sensing component 1, a data acquisition and processing terminal 2, an alarm system 3, and an automatic ventilation control system 4. The light-scattering dust sensing component 1 array is installed around the pulping chamber, and is used to monitor the concentration of dust particles in the air during the pulping process in real time. The data acquisition and processing terminal 2 is installed on one side of the pulping chamber, and is used to process the data collected by the dust sensors, calculate the current dust concentration, and make a judgment. The alarm system 3 is installed on top of the data acquisition and processing terminal 2, and is used to issue alarms in various ways when the dust concentration exceeds a set safety threshold, so as to handle the situation promptly. The automatic ventilation control system 4 is installed around the pulping chamber, and is used to automatically start dust removal equipment or enhance ventilation.

[0026] By installing a new dust concentration detection device that utilizes light scattering sensors and intelligent data processing technology, real-time monitoring and safety management of dust concentration during the ship's pulping process have been achieved. Through linkage with ventilation and dust removal equipment and its explosion-proof design, this device effectively prevents dust hazards, ensures the safe operation of the pulping production line, and adapts to the special requirements of the ship's environment.

[0027] like Figures 1 to 2 As shown, the dust sensing component 1 includes a mounting frame 11, a light scattering dust sensor 12, and a particle size detection sensor 13. The mounting frame 11 is installed around the pulping chamber, and the light scattering sensor and the particle size sensor are installed on the mounting frame 11.

[0028] Light scattering sensors are used to detect the degree of light scattering by airborne dust particles based on the principle of laser or infrared light scattering, and to calculate the dust concentration by observing changes in light signal intensity. These sensors have high sensitivity and are suitable for detecting fine dust in marine dry pulping processes.

[0029] The particulate matter size detection sensor 13 can detect dust particles of different sizes. The particulate matter of concern usually includes PM2.5 and PM10 to ensure the detection of particles of different sizes.

[0030] Meanwhile, the sensor needs to be adapted to the high humidity and high temperature that may exist in the marine pulping environment to ensure the stability and accuracy of the detection results.

[0031] like Figure 1 and Figure 3 As shown, the data acquisition and processing terminal 2 includes a data processing device 21 and a signal receiving device 22. The data processing device 21 is installed on one side of the pulping chamber, and the signal receiving device 22 is installed on the top of the data processing device 21.

[0032] The data collected by the sensors will be analyzed and processed by the data processing device 21. The system collects dust concentration data in real time through the signal receiving device 22 and uses the data processing device 21 to perform rapid analysis to determine whether it exceeds the set safety range. At the same time, it can record and store historical dust concentration data to analyze the trend of dust concentration changes and provide a basis for maintenance and optimization. If the pulping production line is long or has multiple dust generation points, the system can connect multiple sensors to monitor the dust concentration in different areas and perform comprehensive analysis.

[0033] like Figure 1 and Figure 3 As shown, the alarm system 3 includes an alarm light 31 and a buzzer 32. The alarm light 31 is installed on one side of the signal receiving device 22, and the buzzer 32 is installed on the top of the alarm light 31. When the dust concentration exceeds the set safety threshold, the system will issue an alarm in various ways to handle the situation in a timely manner.

[0034] The system alerts operators via warning lights and buzzers 32, facilitating timely responses. It is connected to the data processing device 21 of the pulping system, enabling the transmission of alarm signals to staff for remote monitoring and emergency response. In unattended or remotely monitored scenarios, the system can notify relevant personnel via the network, SMS, or other means.

[0035] like Figure 1 and Figure 4 As shown, the automatic ventilation control system 4 includes a ventilation frame 41, a control motor 42, and a ventilation fan 43. The ventilation frame 41 is installed around the top of the pulping chamber. The control motor 42 is installed on the ventilation frame 41. An output shaft is installed at the output end of the control motor 42. The ventilation fan 43 is installed on the output shaft.

[0036] To prevent dangerous situations caused by excessive dust concentration, the device can be linked with the ventilation and dust removal system. When high dust concentration is detected, the dust removal equipment will be automatically activated or ventilation will be strengthened. When the dust concentration exceeds the preset value, the system will automatically activate the exhaust equipment to remove the high-concentration dust from the cabin or enclosed area. When the dust concentration is reduced to a safe range, the system will automatically reduce the working intensity of the ventilation or dust removal equipment to save energy.

[0037] 1. Because the dust generated during the dry pulping process poses an explosion hazard at high concentrations, the equipment must have good explosion-proof performance:

[0038] Explosion-proof design: The dust concentration detection device and its supporting electrical equipment shall be designed to be explosion-proof to ensure that no explosion will occur in potentially high dust environments.

[0039] Anti-static measures: The surface materials and design of the equipment should have anti-static properties to avoid spark discharge caused by static electricity accumulation.

[0040] Corrosion and vibration resistant design: Due to the humid and vibrating working environment of ships, the outer shell of the equipment should be made of corrosion-resistant materials (such as stainless steel), and the internal structure should be designed to be vibration resistant to ensure that the equipment can work stably during long-term ship voyages.

[0041] 2. Environmentally adaptable design;

[0042] This device is specifically designed for shipboard pulping production lines and must be adapted to the characteristics of the marine environment.

[0043] Salt spray corrosion resistance: Salt spray in marine environments is highly corrosive, and equipment housings and components must be made of materials resistant to salt spray corrosion.

[0044] Moisture and high temperature resistance: High temperature and moisture may be generated during the pulping process, so sensors and electronic equipment must be moisture-proof to ensure stable operation over a long period of time.

[0045] Stable power supply and electromagnetic interference protection: Marine power systems may experience voltage fluctuations and electromagnetic interference, and the equipment should have stable power management and electromagnetic compatibility design.

[0046] 3. Intelligentization and System Integration: The dust concentration detection device can be integrated with the control platform of the entire pulping system to achieve automated management;

[0047] Data sharing and remote control: The detection device can communicate with the ship's central control system via network to achieve data sharing and remote monitoring. Operators can view dust concentration data in real time through a remote terminal.

[0048] Automation and linkage: The detection device is linked with the ship's ventilation, dust removal, alarm and other systems to form a complete automated control system, reducing manual intervention.

[0049] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
