1、 Product Overview

GLT-F seriesHigh temperature dust detectorWidely 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 detection of bag damage of bag type dust remover, online monitoring of dust concentration of various dust removers, materials, boiler flue gas, and gas pipeline dust concentration in iron making gas dedusting process, or monitoring of powder material recovery and total product transportation. Especially for online monitoring of dust concentration in TRT power generation gas pipelines, it plays an important role in real-time monitoring whether the dust in the gas pipelines meets the requirements of TRT power generation, thereby ensuring that the fans are not worn out. This device has high sensitivity, accurate and timely signals, and the sensor can directly output 4-20mA (or RS485 communication, Modbus RTU protocol), reducing signal interference during transmission, making it a practical dust online monitoring device for various industrial enterprises.

High temperature 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.

2、 Working principle

GLT-F seriesHigh temperature dust detectorMeasure the electrostatic induction of dust particles passing through a fixed probe. Dust particles and probes induce static charges, which are amplified by the probe and transmitted to the monitoring and control system. The size of static charge is proportional to the flow rate of dust particles. The high-tech electronic circuit of this system converts this part of the charge into a control signal output, activates the dust over limit emission alarm, and is used to continuously record the total amount or concentration of dust particles.

GLT-F seriesHigh temperature dust detectorProvided the latest global communication coupling technology. This is a modern, precise and stable monitoring technology, particularly suitable for continuous emission recording and data accumulation. The working principle of this monitoring system is to use the charge induction generated by the flow of dust particles around the probe to confirm the online emission amount (mg/sec) or emission concentration (mg/m3) of dust particles. Under relatively stable combustion conditions (i.e. at the same emission point, there is no significant change in flow rate, temperature, pressure, humidity, and particulate properties of smoke particles, with a variation of less than ± 90%), this system can also be used for online monitoring of emission concentration (unit=mg/M3) after direct calibration.
