Special dust meter for steel mills, this security explosive type

1、 Product Overview

Special dust meter for steel mills, this security explosive typeWidely used in various industrial applications, including steelmaking, power generation, petroleum, chemical, pharmaceutical, building materials processing, coal mining and mining, cement manufacturing and packaging industries.Typical applications include detecting bag filter bag damage in bag filtersOn line monitoring of various dust collectors, material dust concentration, boiler flue gas dust concentration, gas pipeline dust concentration in iron making gas dedusting process, or monitoring of powder material recovery and total product delivery.Especially forTRTOnline monitoring of dust concentration in power generation gas pipelines plays an important role, as it can monitor in real-time whether the dust in the gas pipelines meets the requirementsTRTThe requirement for power generation ensures that the fan is not worn out. The device has high sensitivity, accurate and timely signals, and the sensor can directly output4～20mA(orRS485Communication,Modbus RTUAgreement)To reduce signal interference during transmission and become a practical dust online monitoring device for various industrial enterprises.

Dust detectorIt is one of the important equipment to ensure the safe and environmentally friendly operation of dust removal equipment systems. It can integrate operation, display, alarm, and system operation status traceability, achieve real-time online monitoring of dust concentration in the clean air chamber of the dust collector, prevent dust concentration exceeding the standard due to factors such as bag dropping and leakage during operation, eliminate hidden dangers, improve equipment safety guarantee, timely, continuously, and accurately reflect equipment operation status, avoid safety accidents, and reduce equipment accident rate.

twoWorking principle

Special dust meter for steel mills, this security explosive typeThe working principle of is based on the principle of electrostatic induction. The detected dust particles move with the airflow inside the pipeline, and when the dust particles pass through the dust meter probe, they rub and collide with the probe, causing dynamic charge induction and generating charge signals. The dust analyzer will collect dynamic charge signals and obtain corresponding dust particle data through multi-stage operation amplification, filtering, and calculation processing. Continuously collecting dust particle data through a software system, and finally obtaining dust concentration through complex algorithm statistics.The principle of electrostatic detection is widely applied and suitable for the detection environment of gas-solid two-phase flow. The collection process does not require manual intervention, is efficient and convenient, and has strong real-time data.
