Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, and in particular to a high-precision portable VOCs removal efficiency detector. Background Art

[0002] With the acceleration of industrialization and urbanization, the emission of volatile organic compounds (VOCs) has become increasingly serious, posing a threat to the environment and human health. VOCs mainly come from industries such as chemicals, printing, paints, and coatings, as well as motor vehicle exhaust and home decoration. Therefore, it is particularly important to effectively monitor and control the emission of VOCs.

[0003] At present, there is no detector that can directly measure the removal efficiency of VOCs treatment facilities. Instead, a portable FID or PID detector is used to perform a preliminary conversion to calculate the removal efficiency of the treatment facility. The detection efficiency calculated by this method is inaccurate, mainly because 1. The operating conditions (temperature, pressure, wind speed, etc.) at the inlet and outlet of the treatment facility are different. Simply judging the concentration without converting it into concentration calculation under standard conditions will cause inaccurate calculation results. Some instruments such as thermometers, anemometers, and VOCs concentration meters are used in combination, resulting in the on-site instruments switching back and forth. The time interval cannot accurately display the operating conditions at the same time, resulting in calculation errors, and the operation is cumbersome, making it difficult to meet the needs of on-site rapid and accurate detection of VOCs removal efficiency.

[0004] Therefore, it is of great significance to develop a high-precision, portable and easy-to-operate VOCs removal efficiency detector. Summary of the invention

[0005] The technical problem to be solved by the present invention is the problem that the existing VOCs removal efficiency detector has inaccurate accuracy and complicated operation.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a high-precision portable VOCs removal efficiency detector, including an analytical instrument main body, the analytical instrument main body includes a protective cover, and an upper cover is movably provided on one side of the protective cover, a pipeline socket and an antenna are provided on the protective cover, high-pressure steel cylinders and air filters are respectively provided on the other two sides of the protective cover of the analytical instrument main body, an FID detector is provided on the protective cover of the analytical instrument main body, and a sampling pump, an analyzer, a high-precision sensor, and an instrument chip are provided inside the analytical instrument main body.

[0007] As a further solution of the present invention: the protective cover and the upper cover are connected by a plurality of fixing bolts.

[0008] As a further solution of the present invention: a display screen is provided on the main body of the analytical instrument.

[0009] As a further solution of the present invention: the high-precision sensors include but are not limited to temperature sensors, humidity sensors, wind speed sensors, pressure sensors, oxygen content sensors and organic matter detection sensors.

[0010] As a further solution of the present invention: the pipeline socket is connected to the interface of the inlet and outlet of the treatment facility.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. High precision and reliability: The present invention adopts high-precision sensors and advanced acquisition technology to ensure the accuracy and reliability of data. Through real-time monitoring and rapid response, the changes of various parameters in the flue gas can be captured in time, providing important support for environmental monitoring and safety control.

[0013] 2. Portability and ease of use: The present invention greatly reduces the internal structure and weight of the product through modular design. Compared with similar products, it is smaller in size and lighter in weight, making it more convenient and portable for customers to use on site. At the same time, the operation is simple and easy to learn, without complicated settings and installation processes. It measures the working parameters of the import and export in the standard state at one time, saving time and labor costs and improving work efficiency.

[0014] 3. Versatility and comprehensiveness: In addition to accurately determining the VOCs content, the present invention can also obtain and analyze the gas phase parameters of the flue gas, such as oxygen content, humidity, temperature, flow rate, static pressure and dynamic pressure. These parameters are crucial for the comprehensive assessment of the impact and risk of flue gas emissions, and help to promptly identify problems, summarize and analyze data, and take necessary measures.

[0015] 4. Automatic calculation of efficiency: The present invention can conduct a one-time sampling analysis on the factors of the removal efficiency of the VOCs treatment facility, and automatically calculate the removal efficiency of the VOCs treatment facility through the calculation formula built into the instrument chip, thus reducing the error and time cost of manual calculation.

[0024] The main body of the analytical instrument is equipped with a sampling pump, an analyzer, a high-precision sensor, and an instrument chip, and the instrument chip has a built-in calculation formula.

The pipeline socket 1 is connected to the interface of the inlet and outlet of the treatment facility to detect the VOCs concentration at the inlet and outlet.

[0025] Working principle of the present invention:

[0026] 1. Sampling and pretreatment: The detector draws the exhaust gas into the interior through the sampling pump, and then passes through the pretreatment module for dehumidification, dust removal and temperature adjustment to ensure the accuracy of the test results. The filter and adjustment device in the pretreatment module can remove impurities and moisture in the exhaust gas, and adjust the temperature and pressure of the exhaust gas to the standard state.

[0027] 2. Detection and measurement: The pre-treated exhaust gas enters the detection module, and the high-precision sensor begins to detect the VOCs concentration in the exhaust gas. The sensor uses advanced detection technology to accurately measure the VOCs content in the exhaust gas. At the same time, the instrument also measures parameters such as oxygen content, air pressure and glossiness for subsequent data analysis.

[0028] 3. Data processing and calculation: The instrument chip receives the data transmitted by the sensor in real time and automatically processes and calculates the data. The algorithm built into the chip can automatically calculate the concentration value and removal efficiency of VOCs based on the real-time detected data. At the same time, the chip can also display the test results on the display screen in an intuitive way for users to view and analyze.

[0029] 4. Storage and transmission: The detector is equipped with a memory inside, which can automatically save the test data. Users can also export the test data to external devices such as computers and mobile phones through the data output port for further data analysis and processing.
