Embodiment 1

[0020] See Figure 1-3 , the testing wind tunnel system of the dust sensor of the present embodiment comprises: a dust drying device 1, an adjustable speed dust feeding device 2 connected to the dust output port of the dust drying device 1, and a dust wind tunnel 3; Hole 3 includes: air inlet, test section and air outlet.

[0021] The dust output end of the adjustable-speed dust feeding device 2 is set at the air inlet of the dust wind tunnel 3, and the dust sensor 7 and the dust sampler 8 are arranged in parallel in the test section of the dust wind tunnel 3; the outlet of the dust wind tunnel 3 The tuyere is sequentially connected with a dust removal device 5 and a dust discharge device 6 .

[0022] The dust sensor 7 is connected with a dust concentration display device 9 that displays the dust concentration value. The dust sampled by the dust sampler 8 is weighed by the dust weighing device 10 to obtain the dust weight obtained per unit time, and then calculated by the com...

Abstract

The invention relates to a wind tunnel test system for a dust sensor, which comprises a dust drying device, a speed adjustable dust feed device connected with a dust output port of the dust drying device, and a dust wind tunnel. The dust wind tunnel comprises a wind inlet, a test section and a wind outlet; a dust output end of the speed adjustable dust feed device is arranged on the wind inlet of the dust wind tunnel; a dust sensor and a dust sampler are arranged in the test section of the dust wind tunnel parallelly; the wind outlet of the dust wind tunnel is connected with a dust removal device and a residual dust emission device in sequence; the dust sensor is connected with a dust concentration display device which displays a dust concentration value; dust sampled by the dust sampler is weighed through a dust weighing device to obtain the dust weight acquired in unit time; then, a corresponding dust concentration value can be calculated; and finally, the dust concentration value is compared with the dust concentration value displayed on the dust concentration display device, and a measurement error of the dust sensor can be calculated, thereby providing basis for trial manufacture, production and maintenance of the dust sensor.

Description

technical field [0001] The invention relates to a wind tunnel system for testing dust sensors. Background technique [0002] The dust wind tunnel system is specially designed for the actual test, calibration and performance assessment of the newly produced dust sensor, and it is the necessary test equipment for the trial production, production and maintenance of the dust sensor. No such test equipment exists in the prior art. Contents of the invention [0003] The purpose of the present invention is to provide a dust sensor testing wind tunnel system with simple structure and high degree of automation. [0004] In order to achieve the above object, the present invention designs a dust sensor testing wind tunnel system, including: a dust drying device, an adjustable speed dust feeding device connected to the dust output port of the dust drying device, and a dust wind tunnel; The dust wind tunnel includes: air inlet, test section and air outlet; the dust output end of the ...
