summary:

The AML-2030 remote monitoring and quality control instrument for pollution source exhaust gas (hereinafter referred to as the quality control instrument) is a supervisory testing system on-site equipment that can perform quality control, real-time verification and comparison, regular calibration, periodic verification, simple fault diagnosis, and technical indicator sampling on the continuous monitoring system of fixed pollution source exhaust gas through standard gas.

The quality control monitoring platform sends commands to the on-site quality control instrument. After receiving the corresponding command, the on-site quality control instrument interprets the meaning expressed by the command, switches the valve according to the specific command requirements, and sends the standard gas with the required concentration or automatically configured required concentration into the sampling channel of the fixed pollution source exhaust gas continuous monitoring system. The inlet of the standard gas entering the sampling channel can be the proximal inlet or the distal inlet on the chimney; The standard gas generated by the quality control instrument flows through the sampling channel and enters the fixed pollution source exhaust gas continuous monitoring equipment for testing and measurement; After the testing and measurement are completed, the on-site quality control instrument reads the measurement data results, stores relevant information locally, and sends comprehensive information to the remote quality control instrument supervision platform. The platform analyzes the feedback results and generates corresponding reports.

Scope of application:

Continuous monitoring system for exhaust gas from fixed pollution sources, automatic monitoring system for ambient air quality, and continuous monitoring system for volatile organic compounds from fixed pollution sources.

Execution standards:
HJ212-2017 Data Transmission Standard for Pollutant Online Monitoring System
HJ477-2009 Technical Requirements for Online Automatic Monitoring (Monitoring) Data Collection and Transmission Instrument for Pollution Sources

Q/AML33-2019 Remote Monitoring and Quality Control Instrument for Pollution Source Waste Gas

System composition:
The AML-2030 pollution source exhaust gas remote monitoring quality control instrument consists of a quality control instrument supervision platform and an on-site quality control instrument. The quality control monitoring platform remotely operates the on-site quality control instrument through the network to generate a certain concentration of standard gas or zero gas and deliver it to the online smoke monitoring equipment. The on-site quality control instrument collects real-time monitoring data from the online instrument, compares and analyzes it with the concentration of the standard gas, determines its accuracy, and obtains evidence, and uploads the results to the environmental protection department.

Main features and advantages:

7-inch TFT-LCD screen touch display, Chinese and English operation interface;

By using non thermal regeneration drying technology and multi-stage oxidation adsorbents, pollutants such as water, NO, NO2, SO2, etc. in compressed air are removed to produce clean zero air;

The gas flow rate of the prepared zero gas and gas cylinder is controlled by a mass flow controller, which dilutes to produce different concentrations of quality control gas. The reaction is rapid and the flow control is accurate;
Various units such as PPM, PPB, mg/m3, and g/m3 can be selected;
It has the function of monitoring the gas pressure of steel cylinders, and when the pressure is low, it informs in advance to replace the cylinder pressure;
Standard gas humidification function, simulating real smoke emissions;
The system is unmanned and can automatically perform scheduled spot checks on the operation status and data accuracy of smoke pollution source monitoring equipment;
Login password setting and multi-level user management. We have opened certain functions to third-party operators to promote the operation and management of pollution source flue gas and ensure the quality of monitoring instruments;
Equipped with operation log recording function, it can real-time record the sampling personnel, sampling time, as well as the type and concentration of the prepared gas;
It has the function of setting beyond the standard and issuing an alarm. The system can automatically compare, save, summarize, and issue alerts along with data from on-site online monitoring instruments.
Equipped with power-off protection, self-contained power supply, door opening and closing record, remote parameter setting and other functions;

During the calibration period, it has the output function of a relay, which facilitates the data collector to mark the calibration data and avoid affecting the upload and statistics of daily smoke monitoring data.
