Overview

In gas monitoring scenarios in fields such as chemical engineering, metallurgy, environmental protection, and energy, the gas to be monitored often contains interfering components such as dust, water vapor, oil pollution, and corrosive impurities. Directly entering the analyzer can cause problems such as sensor poisoning, drift in detection accuracy, and shortened equipment life. Ma'anshan Maisite Intelligent Technology Co., Ltd. (hereinafter referred to as "Maisite Intelligent") is deeply engaged in gas monitoring full chain solutions. With the core advantages of "efficient purification, stable temperature control, and intelligent adaptation", the independently developed gas pretreatment system has become the "pre guardian" of accurate monitoring, and has formed a collaborative linkage with the company's gas online analyzer to provide reliable monitoring support for various industries throughout the entire process.

Ma'anshan Maisite Intelligent Technology: Gas Pre treatment System, Building a Front Line for Precise Monitoring

Accumulation Empowerment Preprocessing: Breakthrough in Extending the R&D Strength of the Whole Chain

The years of accumulation of Maisite Intelligence in the field of gas monitoring have laid a solid foundation for the research and development of gas pretreatment systems. The core R&D team of the company not only includes experts in sensor technology and data algorithms, but also integrates professionals from fields such as fluid mechanics, materials science, and thermal control to carry out targeted R&D for gas impurity characteristics in different industries. 30% of the annual R&D investment is dedicated to pre-processing technology iteration, and a total of 12 pre-processing related utility models have been obtained, including multiple industry gaps in technologies such as "multi-stage gradient purification device" and "intelligent constant temperature and humidity control system".

Relying on standardized intelligent production workshops, Maisite Intelligent has established an independent production line for the core components of the pre-processing system. From the filtration membrane, condensation chamber to the control module, all are independently manufactured and rigorously tested to ensure product consistency and stability. The company has passed ISO9001 quality management system certification and CE certification. The pre-treatment system and gas online analyzer cover more than 20 provinces in China and overseas markets such as Southeast Asia and the Middle East, and are suitable for more than a thousand complex monitoring scenarios such as chemical parks, power plants, and steel plants.

Four core technologies: solving the problem of pre-processing complex working conditions

The core competitiveness of the Maisite intelligent gas pretreatment system lies in its precise control of impurity treatment requirements under different working conditions. Through four key technological innovations, it achieves a treatment effect of "purification, parameter stability, extremely low loss, and convenient operation and maintenance":

1. Multi level gradient purification technology: targeted removal of multiple types of impurities

The system adopts a three-level processing architecture of "pre filtration deep purification precision filtration" to achieve targeted removal for different types of impurities. The front-end is equipped with a self-developed anti clogging sampling probe, with a built-in wedge-shaped filter that can filter dust particles with a particle size of ≥ 5 μ m, with a filtration efficiency of 99.5%. It also has an automatic blowback function (blowback pressure of 0.4-0.6MPa, blowback time can be customized), effectively avoiding dust accumulation and blockage; The deep purification stage flexibly configures purification components based on gas characteristics, such as using high-efficiency condensation dehydration devices for high water vapor gases, with dehydration efficiency ≥ 99%, and dew point can be reduced to below 5 ℃; For oil pollution and organic impurities, a hydrophobic PTFE filter membrane+activated carbon adsorption combination is used, with an interception rate of 99.8% for oil pollution and an adsorption efficiency of over 95% for VOCs impurities; The precision filtration stage adopts a 0.1 μ m ultrafine filter membrane to ensure that the cleanliness of the gas entering the analyzer meets the detection requirements. In the dust and moisture tail gas monitoring project of a certain chemical enterprise, after adopting this system, the service life of the analyzer sensor has been extended from 8 months to 24 months.

2. Intelligent constant temperature and humidity control technology: stable monitoring of basic parameters

Temperature and humidity fluctuations are important factors that cause drift in detection data, and Meister Intelligent uses a dual technology of "semiconductor condensation+PID temperature control" to achieve precise regulation. The system is equipped with high-precision temperature sensors (accuracy ± 0.1 ℃) and humidity sensors (accuracy ± 2% RH), which quickly cool down and remove water through semiconductor condensation modules, and are assisted by electric heating wires to achieve stable gas temperature of 20-25 ℃± 0.5 ℃ after treatment; For low humidity demand scenarios, adsorption dehumidification modules can be used to control gas humidity within the range of 30% -50% RH. In a monitoring project of a power plant in a cold northern region (-30 ℃), the system can stabilize the low-temperature and high humidity flue gas to 25 ℃ and 40% RH, ensuring that the fluctuation amplitude of the analyzer data is ≤± 0.5% FS, far better than the industry average of ± 2% FS.

3. Low loss flow path design technology: ensuring the authenticity of monitoring

To avoid component loss or deterioration of the tested gas during the preprocessing process, the system adopts a full flow path optimization design. The flow path material is made of 316L stainless steel and PTFE, which have strong corrosion resistance and an adsorption rate of ≤ 0.1% for active gases such as H ₂ S and SO ₂; The inner diameter of the flow path is optimized with a diameter of 6mm, combined with low resistance joints, to achieve a system pressure loss of ≤ 0.02MPa and a stable gas flow rate of 0.5-1L/min, ensuring that the gas to be measured quickly enters the analyzer with a response delay of ≤ 3 seconds; For gases that are prone to condensation, the flow path is wrapped with a heat tracing strip (with an adjustable temperature range of 0-120 ℃) to effectively prevent gas condensation and precipitation during transmission, ensuring the integrity of the components. In the monitoring project of blast furnace gas in a certain steel plant, the design achieved a 99.3% consistency between the monitoring data of core components such as CO and CO ₂ and laboratory analysis data.

4. Full process intelligent control technology: reducing operation and maintenance costs

The system is equipped with the "MS-P Intelligent Control System" independently developed by Maisite, which has multiple intelligent functions: real-time monitoring of key parameters such as filter pressure difference, temperature, humidity, etc. When the filter pressure difference is ≥ 0.1MPa or the parameters exceed the standard, the sound and light alarm will be immediately activated and pushed to the cloud platform; Support timed settings for operation and maintenance actions such as automatic blowback and regular calibration. The blowback cycle (10 minutes to 24 hours) and calibration frequency can be customized according to the working conditions; Through interfaces such as 4G and Ethernet, it is linked with analyzers and monitoring platforms to achieve synchronous display and remote control of pre-processing status and monitoring data. In a cluster monitoring project of a chemical industrial park, the system reduced the frequency of manual operation and maintenance from once a day to once a week, and reduced operation and maintenance costs by 70%.

Collaborative service guarantee: worry free adaptation throughout the entire process

Maist Intelligent adheres to the concept of "full chain service" and provides one-stop services from solution design to operation and maintenance support for gas pretreatment systems. In the early stage, a professional team will conduct on-site investigations of the working conditions, and customize personalized pre-treatment plans based on parameters such as gas composition, temperature, and humidity to ensure compatibility with the analyzer; During the installation phase, a certified engineer will come to the site to complete the linkage debugging of the system and analyzer, and synchronize the calibration of key parameters; After sales rely on 8 regional service centers across the country, providing "2-hour response, 24-hour on-site" services, regularly conducting system inspections and filter replacement, and providing free technical training to ensure that operators are proficient in intelligent control functions.

Conclusion: Strengthen the front line of defense and ensure worry free precise monitoring

As the "first hurdle" for precise monitoring, the performance of the gas pretreatment system directly determines the reliability of the entire monitoring system. Ma'anshan Maisite Intelligent Technology, with its independently innovated core technology and full scenario product matrix, has formed a synergistic advantage between the preprocessing system and the gas online analyzer, solving the problem of monitoring interference under complex working conditions.
