Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wind measurement, in particular to a novel anti-blocking matrix type wind flow measuring device. BACKGROUND

[0002] The novel anti-blocking matrix type wind flow measuring device is a high-efficiency measuring device for industrial ventilation, flue gas emission or pipeline gas flow monitoring, and is particularly suitable for complex working conditions such as containing dust, particulate matter or high humidity that are prone to blockage. The core design goal is to solve the problems of traditional wind flow measuring devices such as easy blockage, frequent maintenance, and reduced measurement accuracy.

[0003] In some industrial environments, there are a large number of dust particles in the airflow. These dust particles will gradually accumulate on the surface of the probe of the anemometer, changing the shape and surface characteristics of the probe, thereby affecting the flow state and pressure distribution of the airflow, causing the measurement result to deviate, and shortening the service life of the probe. When the airflow is transported through two groups of pipelines, there may be a pressure difference. The prior art is relatively difficult to detect wind flow through the pressure difference, and the practicality is relatively single. In addition, some devices are relatively difficult to change the flow direction and velocity distribution of the airflow at the same time, increasing the vortex and turbulent flow of the airflow, and reducing the stability of the airflow.

[0004] Finally, the prior art is relatively difficult to reduce the vortex and secondary flow generated by the inclined pipe to a certain extent when transporting the airflow through the inclined pipe, resulting in uneven flow velocity distribution, affecting the wind flow detection result at the intersection of the inclined pipe and the straight pipe, and the intelligent degree is relatively low. After detecting the three groups of data, the prior art is relatively difficult to fuse the three groups of wind flow data collected, reducing the accuracy and reliability of the measurement result, and some devices are relatively difficult to realize data storage and encryption at the same time, and the security is relatively low.
