1. Overview

This manual describes the installation, operation, inspection, and maintenance of this smoke concentration monitor.

The instrument is based on the principle of backscattering of smoke particles and is used for online continuous measurement of particulate pollutants from fixed pollution sources.

be careful:

This smoke concentration monitor uses a 10mW, 650nm semiconductor laser. Direct injection of the laser beam and reflected light into the eyes can cause serious damage.

Do not look directly at the laser beam and its reflected light

Without proper training, operations beyond the scope of this manual are not allowed.

2. Scope of application

stem or root of plantsSmoke and dust monitoring deviceReal time continuous measurement of particulate pollutant concentration for various pollution emission sources, compatible with smoke monitoring systems, and capable of singleoneConnect one or several devices to form a smoke and dust monitoring network, sharing a front desk. The instrument can be used for monitoring smoke and dust in power plants, steel mills, cement plants, etc. It can also be used for process control of dust removal equipment and other powder engineering.

3. Technical features

lSmoke and dust monitoring deviceAdopting the principle of laser backscattering. Not afraid of mechanical vibration of the flue and beam oscillation caused by uneven refractive index due to uneven flue gas temperature;

Single end installation, no need for optical alignment. The instrument design process greatly reduces the complexity of on-site installation. The installation of instruments and rainproof systems only requires a screwdriver for electrical connections, which can be completed within 20 minutes. Installation and maintenance are extremely simple, greatly reducing the many problems caused by on-site installation and debugging;

Adopting standard 4-20mA industrial standard current output, easy to connect;

The overall power consumption of the instrument is very low, about 5W;

Place the calibrator on site to avoid confusion and loss;

High resolution, suitable for monitoring low concentration emissions as well as high concentration emissions;

Non point measurement, with a large sampling area, can be used for chimneys of various diameters.

5. System principle and composition

The schematic diagram of the host structure is shown in Figure 1

The host includes a laser light source and power control unit, a photoelectric sensing and small signal preprocessing unit, a scattered light receiving unit, a display and input unit, an output driving unit, and a main control unit. The 650nm beam emitted by the laser enters the emission source at a small angle, and the laser beam interacts with smoke particles to produce scattered light. The backscattered light enters the sensor through the receiving system and is converted into an electrical signal for processing The circuit part realizes the functions of photoelectric conversion, modulation of laser beam, signal amplification, demodulation, power control of light source, and V/I conversion.
