Dust particle detector

Abstract

The invention relates to the field of detection and particularly relates to a dust particle detector. A technical problem to be solved is to provide the dust particle detector. The dust particle detector comprises an air inlet drying system, a detection system and the like, wherein the air inlet drying system is connected with the detection system. According to the dust particle detection device, the single method that air flow is simply matched with laser and a photoelectric receiver for dust particle detection traditionally is abandoned, the defect that detection air continuously and repeatedly enters the device, so dust particle detection precision is not high is overcome, and the detected dust particles are attached and collected; and meanwhile, according to the characteristic that the distribution rule of the dust particles in the air is not fixed due to different particle sizes, the air at different heights in the same space is drawn to realize the detection of the dust particles, so an accurate detection result is obtained.

Description

technical field [0001] The invention relates to the detection field, in particular to a dust particle detector. Background technique [0002] Dust particle detector, also known as dust particle counter, is an instrument used to measure the number and particle size distribution of dust particles per unit volume in a clean environment. [0003] The traditional dust particle detector is too single for the detection of dust particles. It simply uses air flow to cooperate with laser and photoelectric receivers to detect dust particles; but the disadvantage of this method is that the detection air will continuously enter the device repeatedly, making the dust particles The detection accuracy is not high, and according to the different particle sizes of dust particles, the distribution law in the air is not fixed, so the traditional method of directly extracting air is difficult to obtain accurate detection results. [0004] In view of the above problems, a dust particle detector ...

[0005] In order to overcome the single detection of dust particles in the traditional dust particle detector, it simply uses air flow to cooperate with laser and photoelectric receivers to detect dust particles; but the disadvantage of this method is that the detection air will repeatedly enter the device, making The accuracy of dust particle detection is not high. At the same time, according to the different particle sizes of dust particles, the distribution law in the air is not fixed. Therefore, it is difficult to obtain accurate detection results in the traditional way of directly extracting air. The technical problem to be solved is : provide a dust particle detector
