2. Product introduction of Online odor monitoring system

Online odor monitoring system consists of power supply system, gas collection system, sensor monitoring system, data control system, display and transmission;

The Online odor monitoring system uses a unique compensation and anti-interference algorithm. The system uses array sensors to detect three major categories (S series, N series, VOCs series) in accordance with national standards. The monitoring parameters mainly include ammonia, hydrogen sulfide, trimethylamine, and carbon disulfide. , methyl mercaptan, styrene, methyl sulfide, dimethyl disulfide, single gas and composite odor concentration OU values of 8 gas substances, a total of nine parameters.

There are four conventional parameters for online monitoring of odor: NH3, H2S, TVOC, and OU value;

Power supply system: Mains power supply conversion system

Gas collection system: The air in the environment is pumped into the gas collection chamber (sniffing bag) through the sampling pump and gas collection rod (including the flow control unit) for detection and analysis;

Monitoring system: gas sensor detection module, meteorological parameter detection module, responsible for the identification and analysis of different odor components in odor samples; sensor array design, integrated multi-gas cross-interference algorithm, temperature and humidity compensation algorithm Control system: the control unit controls each After the sensor detection data is collected, the big data model is used for analysis and calculation to obtain accurate data;

Display system: presents the collected and processed monitoring factor data in an easy-to-understand manner; the chassis is integrated with a 7-inch high-definition color screen, which can be equipped with an external LED display screen or a large-screen control center;

Transmission system: The transmission unit passes DTU or data acquisition instrument (2-channel 232 interface, 3-channel 485 interface, 2-channel Ethernet interface, other interfaces are optional), transmission protocol J212; the data can be displayed on the smart environmental protection supervision platform, as required Party designated platform, Environmental Protection Bureau platform, etc.;

3. Product features of Online odor monitoring system

Gas monitoring parameters: ammonia, hydrogen sulfide, trimethylamine, carbon disulfide, methyl mercaptan, styrene, methyl sulfide, dimethyl disulfide; dimensionless OU value meteorological monitoring parameters: temperature, humidity, wind speed, wind direction, air pressure, Lighting, noise, etc.

Features:

▲Customized design of intelligent modules:

The 9 index target gases including odor OU value, ammonia, hydrogen sulfide, trimethylamine, methyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide, and styrene can be combined in any way, and the technical principles are not limited. The detection range is not limited, and the sensor is pluggable;

At the same time, it supports the monitoring of meteorological parameters, temperature and humidity, wind speed and direction, and atmospheric pressure.

Product introduction and application areas

Portable portable composite gas gas detector

(also called portable composite gas analyzer)

It is a high-precision pump-type composite gas analyzer suitable for complex environmental detection. With built-in pre-processing, error compensation, anti-electrical interference, wireless signal output and other functions, the analyzer can detect up to 8 gas types at the same time.

The portable gas detector has built-in optional wireless transmission and can be connected to the Ampal server to realize functions such as remote monitoring, remote setting of alarm values, and remote calibration.

Main purposes and scope of use: Suitable for professional technicians, operators, leaders and other workers.

6. After-sales service commitment

Reasons for purchasing Online odor monitoring system:

1Objective assessment of odor pollutant emissions

For production enterprises, it is inevitable to discharge or leak a small amount of odorous pollutants during the production process. By installing the Online odor monitoring system, the pollutant emissions can be continuously monitored 24 hours a day, and the over-standard alarm function in the system can be used to It is possible to detect and deal with excessive pollutants in a timely manner; by analyzing real-time data and historical data, we can summarize patterns, identify problems, improve corporate management levels, and ensure that pollutant emissions comply with national standards.

2Response to residents’ complaints

When an odor pollution accident occurs, companies that have installed the Online odor monitoring system can take timely response measures to reduce the hazards of the accident, give residents a proper explanation, and improve the harmonious relationship between the company and residents; the environmental regulatory department uses the odor monitoring system to Conduct on-site monitoring of sudden odor pollution accidents, obtain monitoring results immediately, inform enterprises and residents of the pollution situation on-site, and improve the credibility of environmental protection departments.

3 Investigation of pollution sources of odor accidents

Enterprises that have installed an Online odor monitoring system can use odor monitoring data combined with meteorological monitoring data to eliminate or determine whether pollutants are emitted by their own companies; environmental supervision departments can use the odor monitoring system to establish a database of characteristic pollutants of enterprises within their jurisdiction. When a pollution accident occurs, polluting enterprises can be quickly identified by combining meteorological data.

4. Improve public image

4.1 Enhance corporate public image and increase brand value

Through the installation of the Online odor monitoring system, we can effectively reduce the occurrence of odor pollution accidents, live in harmony with surrounding residents, and respond to the policy of "lucid waters and lush mountains are valuable assets" strongly advocated by the country. Supplemented by appropriate media promotion, it can effectively enhance the corporate image, increase brand value, and can also become a bonus for corporate financing.

4.2 Improve the credibility of environmental protection authorities

The timely handling of odor pollution accidents has always been one of the headaches for environmental protection regulatory authorities. In the past, when there was a lack of effective monitoring methods, residents often mistakenly believed that the competent authorities were inactive and shielding polluting enterprises; while production companies believed that regulatory authorities were stuck in their efforts. Arbitrary fines will have a negative impact on the government's image. Through the use of odor monitoring analyzers, monitoring data can be clearly provided on site, effectively improving the credibility of regulatory authorities.
