ZR-3702 integrated flue gas mercury sampler Introduction
ZR-3702 integrated flue gas mercury sampler is designed in strict accordance with the requirements of HJ917-2017 standard. It integrates sampler adsorption tube, whole-process heat tracing, refrigeration dehumidification and data processing, which improves the portability of on-site sampling. The instrument is suitable for the determination of gaseous mercury in the exhaust gas of coal-fired power plants equipped with desulfurization, denitrification and dust removal.
Executive standard
GB/T 16157-1996 "Measurement of particulate matter in fixed pollution source exhaust gas and sampling method of gaseous pollutants"
HJ/T48-1999 "Technical Conditions for Soot Sampler"
EPA Method 30B Determination of Gaseous Total Mercury Emissions from Coal-Fired Sources by Adsorption Tube Method
HJ917-2017 "Determination of gaseous mercury in fixed source of waste gas - Activated carbon adsorption / thermal cracking atomic absorption method" Features
1. The sampling tube is heated all the way, and the back end is quickly cooled and dehumidified by Peltier to prevent the condensed water from flowing back or sucking into the mercury adsorption tube, and at the same time obtaining the dry volume;
2, sampling tube and host integrated design, small size, light weight, good portability;
3. The titanium alloy material with light weight, high temperature resistance and corrosion resistance is used to heat the adsorption chamber and the sampling tube, which is suitable for long-term sampling;
4. The soft connection mode between the adsorption tube and the adsorption chamber is easy to replace, so as to avoid air leakage due to the rigid connection;
5. Built-in two-way high-negative pressure sampling pump, with 2 completely independent mercury adsorption sampling channels, with air tightness detection function;
6. The sampling flow rate and sampling time can be set. The high-precision sensor is used to automatically measure the working condition parameters such as atmospheric pressure and gauge pressure, and automatically calculate the sampling flow rate and volume of the standard condition;
7. The instrument has a power-down protection function, and the caller automatically resumes sampling;
8, optional GPRS or Bluetooth module, through the mobile phone or tablet as a handheld device on-site control instrument, or remotely operate the instrument and real-time monitoring of the instrument's working status.
9, high-brightness color touch screen + button operation, wide temperature work, easy to operate, good human-computer interaction;
10, with DC power supply interface, can be connected to the lithium battery for power supply;
11. The condensing drainage pipe has a heating function to prevent condensation and freezing of the drainage holes in a low temperature environment;
12. Reserve the RS485 standard communication interface, which can be used in conjunction with the supporting instruments;
13, built-in lithium battery, can meet the instrument query, print, export and other related functions;
14. Optional Bluetooth printer for data printing, support U disk data export. Technical parameters
