Device and method for testing airflow distribution of dust remover

Abstract

The invention relates to a method for testing the airflow distribution of a dust remover. The method is characterized by comprising selecting a test cross section of the dust remover and determining test points; installing steel pipes (1) according to the positions of the test points, wherein wind speed test probes are embedded in the steel pipes (1); adjusting the positions of the probes (5) in the steel pipes (1) so as to be consistent with the those of the test points; enabling a cable (8) connected to the probes (5) to extend out of the dust remover (7) from the steel pipes (1)in order tobe connected with a controller (6); turning on a fan and turning on an airflow distribution test device after the air volume and the air pressure of the fan are stabilized, transmitting the measured data to the controller (6) through the cable (8) so as to automatically calculate the mean square error of the airflow distribution and display the wind speed at each test point in real time. The method avoids the injury caused by the operation of a worker in the dust remover, is high in safety factor and easy and quick to operate, simultaneously measures multiple test points, can test the airflowdistribution in any partial range of a distribution point cross section, and improves the measurement efficiency and accuracy.

Description

technical field [0001] The invention relates to a test device, in particular to a test device and method for airflow distribution of a dust collector. Background technique [0002] In actual production, there are many factors that affect the purification efficiency of the dust collector, among which whether the air flow is evenly distributed in the dust collector has a great impact on the dust removal efficiency. When the airflow is evenly distributed, the dust collector can operate at its best; when the airflow is unevenly distributed, there is a big difference between the dust removal efficiency in the area with low flow velocity and the area with high flow velocity, and the total efficiency of dust removal will decrease, and the worse the airflow distribution will be. Uniformity, the lower the overall efficiency of dust removal. [0003] At present, in order to obtain a more accurate actual airflow distribution, the following two methods are usually adopted: first, the s...
