3 Overview

Dust sampler is measuring flue, chimney and general dust particles by sampling the gas pipeline manner by filtration weighing method Particulate matter concentration of the instrument. Filter dust sampler weighing method principle is. a certain amount of dust gas through the known mass of the filter cartridge or filter dust Particles are retained by the removal of uncombined water, according to the incremental samples before and after the filter cartridge or filter paper, calculated per unit volume of gas The particulate mass. Mentioned below refers to filter dust sampler dust sampler weighing method. Dust sampler type dust sampler is divided into manual and automatic type dust sampler. Manually type dust sampler is measured in advance before sampling the temperature at the sampling point, pressure, gas flow rate and other parameters, namely, Sample flow sampling points required when calculating dust sampler to work, you want to manually adjust the sampling flow through to Demand flow values sampled. The structure shown in Figure 1. Figure 1 Manually type dust sampler chart 1- sampling device; 2- pressure measuring device; 3- a temperature measuring device; 4- flow measurement and control device; 5- suction pump Auto-type dust sampler is a measurement and control system in accordance with various sensors to detect pressure, temperature and other parameters, by , And calculates the corresponding control signal, the control circuit adjusts the suction pump pumping capacity, to achieve the appropriate traffic. from
