Industry Background:

Iron and steel smelting is an important source of environmental pollution. The production process from raw materials, coking, sintering to ironmaking, steelmaking, continuous casting as well as rolling produces a large amount of exhaust gases, causing serious environmental pollution. In this process its process involves the control of oxygen concentration, carbon monoxide, sulfur dioxide, hydrogen sulfide, nitrogen oxides and other gases.

Solution:

Monitoring location: sintering fan room, sintering area, blast furnace fan room, coal spraying area, roll weighing area, blast furnace body area, cloth bag area

Monitoring factors: combustible gases, oxygen, carbon monoxide, sulfur dioxide, hydrogen sulfide, nitrogen oxides

Data transmission: one kind is wired transmission, one kind is wireless transmission.

Wired transmission: The gas detection and alarm instrument is transmitted to the gas alarm controller in the form of 4-20mA current signal or RS485 bus digital signal, which is then converted into RS232 signal and transmitted to the computer terminal;

② wireless transmission: gas detection and alarm instrument through the RTU433 or GPRS wireless transmission form of data transmission to the gas alarm controller, and then through the Internet network, wireless transmission to the computer terminal.

Program composition:

Front-end media monitoring: gas detection and alarm instrument, shielded cable wire, optical fiber, wireless module, switch, gas alarm controller, PLC, DCS, etc..

Terminal monitoring and management: client gas online monitoring software platform, monitoring center monitoring platform system.
