Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust meter sealing flange technology, specifically to the sealing flange structure of an electric charge dust meter. Background Technology
[0002] The concentration of dust in the air is measured using the charge induction method. The basic principle of the charge induction method for dust concentration detection is that dust particles collide and rub against each other during gas transport, causing them to lose electrons and form charged particles. As the dust concentration changes, the amount of charge also changes according to a certain pattern. Therefore, by measuring the amount of charge carried by the flowing dust and performing corresponding data conversion and processing, the dust concentration can be obtained. The flange is used to connect the dust meter and the pipe being measured. It is usually a circular disc structure with multiple bolt holes.
[0003] Charge dust monitors are usually connected by flanges and bolts. Due to the nature of the gas in the flue and the sealing problem between the two flanges, the gas is prone to leaking between the two flanges. Over time, the bolt threads will rust, eventually making disassembly and maintenance difficult. In addition, the detection rod mechanism of most existing charge dust monitors is fixed, which makes it unsuitable for pipes of various diameters. Utility Model Content
