Detailed Introduction
3072 type intelligent dual channel flue gas sampler
1、 Product Overview: This instrument is specifically designed for sampling gaseous pollutants in fixed pollution sources. According to the national standard HJ543-2009 "Determination of Mercury in Fixed Pollution Source Waste Gas - Cold Atomic Absorption Spectrometric Method (Provisional)", it is compatible with the Laoying 1080C flue gas preprocessor and can be used for the determination of mercury in flue gas. Design an embedded software control platform with dual channel mode, combined with high-tech in the fields of computers, sensors, and new materials, to enable the instrument to have the characteristics of small portability, reliable performance, stable and accurate flow, and long service life. It can be used for measuring the emission concentration and total amount of gaseous pollutants in various fixed pollution sources such as boilers, flues, industrial furnaces, etc. It can automatically detect parameters such as pressure, temperature, atmospheric pressure, and ambient temperature before the flow meter, and automatically calculate the sampling volume under standard conditions.
2、 Implementation standards: HJ/T47-1999 "Technical Conditions for Smoke Samplers", HJ/T397-2007 "Technical Specification for Monitoring Fixed Source Waste Gas", HJ543-2009 "Determination of Mercury in Fixed Pollution Source Waste Gas - Cold Atomic Absorption Spectrometric Method (Provisional)"
3、 Product features: ◆ Ultra low frequency brushless sampling pump with strong load capacity and long service life, ensuring reliable operation for a long time. ◆ Small size, light weight, simple operation interface, easy to carry. ◆ High precision electronic flowmeter control, real-time monitoring of temperature and pressure, automatic flow adjustment. ◆ Temperature compensation, improving sensor measurement accuracy. ◆ Two stage high-efficiency dust filtration design, with high-quality titanium dust filter tube at the front end of the sampling tube and polytetrafluoroethylene filter element for the host. ◆ Absorption bottle directly hung on the heating sampling gun to shorten the pipeline connection length and reduce adsorption loss. ◆ Dual channel air path color * * separation, easy to connect and use. ◆ Large capacity, high-efficiency anti backflow suction dryer, variable diameter air path connection tube design, efficient water removal, avoiding backflow of test solution. ◆ Multi sampling mode, dual sampling flow rate, start time Sampling time can be controlled separately. In case of sampling failure, the instrument has automatic protection function. It automatically accumulates sampling volume and converts it to standard sampling volume based on atmospheric pressure and temperature. During the sampling process, if there is a power outage, the sampling data will be automatically memorized and saved, and the sampling during power outage will be automatically restored. The wide temperature LCD display screen is suitable for clear display in outdoor low temperature and low dark environments
