Description

Technical Field

[0001] The invention relates to the technical field of air volume measurement, in particular to a novel anti-blocking matrix air volume measurement device. Background Art

[0002] The new anti-blocking matrix air volume measurement device is a highly efficient measurement device used for industrial ventilation, flue gas emissions, or duct airflow flow monitoring. It is particularly suitable for complex working conditions prone to clogging, such as those containing dust, particulate matter, or high humidity. Its core design goal is to solve the problems of traditional air volume measurement devices such as easy clogging, frequent maintenance, and reduced measurement accuracy.

[0003] In some industrial environments, the airflow contains a large amount of dust particles, which will gradually accumulate on the surface of the anemometer probe, changing the shape and surface characteristics of the probe, thereby affecting the flow state and pressure distribution of the airflow, causing deviations in the measurement results and shortening the service life of the probe. When the airflow is transported through two sets of pipes, there may be an air pressure difference. Existing technologies are difficult to detect air volume based on the air pressure difference, and their practicality is relatively simple. In addition, some equipment finds it difficult to simultaneously change the flow direction and velocity distribution of the airflow, which increases the vortex and turbulence of the airflow and reduces the stability of the airflow.

[0004] Finally: When the existing technology transports airflow through an inclined tube, it is difficult to reduce the eddy currents and secondary flows generated by the inclined tube to a certain extent, resulting in a relatively uneven flow velocity distribution, affecting the air volume detection results at the intersection of the inclined tube and the straight tube, and the degree of intelligence is low; after the existing technology detects the three sets of data, it is difficult to fuse the three sets of collected air volume data, which reduces the accuracy and reliability of the measurement results, and it is difficult for some equipment to achieve data storage and encryption simultaneously, and the security is low.
