Atmospheric dust concentration measurement equipment and method

Abstract

The invention discloses atmospheric dust concentration measurement equipment and a measurement method of the atmospheric dust concentration measurement equipment. The measurement equipment comprises a case, wherein a vertical pipe is arranged at the upper end of the case; a heating pipe and a dehumidification pipe are fixed in the vertical pipe from top to bottom; the lower end of the heating pipe is butted with the upper end of the dehumidification pipe; a sampling port is formed in the upper end of the heating pipe; a dust concentration measuring instrument is arranged in the case; an inlet of the dust concentration measuring instrument is communicated with the lower end of the dehumidification pipe; an outlet of the dust concentration measuring instrument is communicated with a suction power device; the suction power device is fixed in the case. According to the measurement equipment, moisture in atmosphere can be rapidly removed, so that humidity of dust-containing air entering the atmosphere sampling measurement equipment is low, the influence of the air humidity on the accuracy of the dust concentration detection result is reduced as much as possible, and the accuracy of the detection result of the dust concentration measuring instrument at high air humidity is improved.

Description

technical field [0001] The invention relates to an atmospheric dust concentration measuring device, which is suitable for accurate measurement of the dust concentration in the atmosphere, and also relates to a measuring method. Background technique [0002] As the current air pollution is getting more and more serious, people are sampling and monitoring the air components more and more frequently. A kind of equipment, which mainly includes a sampling port set in the atmospheric environment, a dust concentration measuring instrument, but the measurement results of the atmospheric dust concentration measuring equipment of this structure are inaccurate, the reasons are: [0003] Due to the constant change of temperature and humidity in the actual atmospheric environment, especially the humidity value has a great influence on the dust concentration measuring instrument, the result detected by the dust-containing wet air entering the measuring device from the sampling port is dif...

Problems solved by technology

[0002] As the current air pollution is getting more and more serious, people are sampling and monitoring the air components more and more frequently. This kind of equipment mainly includes a sampling port and a dust concentration measuring instrument arranged in the atmospheric environment. However, the measurement results of the atmospheric dust concentration measuring equipment of this structure are inaccurate, and the reasons are:

[0003]Because the temperature and humidity in the actual atmospheric environment change from time to time, especially the humidity value has a great influence on the dust concentration measuring instrument, the wet air containing dust enters from the sampling port into the There are differences between the results detected by the measuring equipment and the actual amount of dust in the atmosphere, resulting in inaccurate results

Especially when dust with high moisture content enters the measuring equipment, it will adhere to the air channel and the dust concentration measuring instrument, which not only causes inaccurate test results, but also sticks to the air channel and the dust concentration measuring instrument and is difficult to discharge , thereby increasing the number of cleanings, which results in a reduction in the amount of dust and affects the accuracy of the test results of the atmospheric measurement equipment
