Abstract

The invention discloses a method of measuring dust concentration. The method comprises: emitting a laser to to-be-measured gas, detecting a transmitted light signal and a scattered light signal passing through the to-be-measured gas, carrying out amplification processing on the transmitted light signal and the scattered light signal, and then carrying out conversion processing to obtain the dust concentration of the to-be-measured gas. According to the measuring method of the invention, measurement accuracy of dust is further improved through combining the transmitted light signal and the scattered light signal, an optical system can be cleaned synchronously, and manual post-maintenance is omitted.

Description

technical field [0001] The invention belongs to the technical field of dust measurement, and relates to dust concentration measurement, in particular to a method for measuring dust concentration. Background technique [0002] With the development of industry, the pollution of dust in the air is becoming more and more serious. Because the dust in the air is not only a serious hazard to human health, but also in some occasions where the dust concentration is too high, there is a potential risk of dust explosion, so the detection of dust concentration is very important. [0003] At present, there are mainly the following methods for measuring the dust concentration: one is the sampling method of first depositing dust and then measuring, that is, taking a part of representative samples containing dust particles from the area to be tested and sending them into the subsequent analysis and measurement device system to measure the concentration and particle size of dust particles; ...
