Boiler flue gas desulfurization gas monitoring system

Automatic control system for water quality analyzer, boiler flue gas desulfurization gas monitoring system

Detailed description

Economic development has gradually improved people's living standards, but at the same time, it has also led to a continuous deterioration of the living environment around them. People have gradually realized the harm of environmental pollution and put forward the requirement for coordinated development between the economy and the environment. Air pollution is closely related to people's lives, as it directly causes an increase in population mortality, damages ecosystems, and causes huge economic losses. The exhaust gases emitted by industries such as thermal power plants and steel mills are the main source of air pollution.

In view of this, relevant national departments have formulated regulations requiring power plants to add desulfurization PLC control systems. The main method for reducing sulfur dioxide emissions in the current industry is flue gas desulfurization. After the boiler burns coal, the flue gas is washed with lime water to absorb sulfur products. After washing the lime water with gas, sodium hydroxide NaOH is added for regeneration, which is desulfurization.
At present, the widely used flue gas desulfurization processes include limestone (lime) gypsum wet desulfurization, spray drying desulfurization, flue gas circulating fluidized bed desulfurization, seawater desulfurization, and electron beam desulfurization. Priority is given to using limestone gypsum wet desulfurization for large units exceeding 200MW in China. Analyze instrument monitoring data, upload it in real-time to the data center, and monitor the data.

The practical application of gas analysis instruments in flue gas desulfurization systems, with a focus on the design and practical application of the limestone (lime) - gypsum wet desulfurization monitoring system.
