A mercury-containing fumes emission continuous monitoring system and a monitoring method thereof

Abstract

The invention relates to a mercury-containing fumes emission continuous monitoring system and a monitoring method thereof. The monitoring system comprises a sampling device, a reactor, a gas and water separating device, and a mercury concentration measuring device which are sequentially connected through a pipeline; the reactor is connected with a first container containing a divalent mercury adsorption solution through a first peristaltic pump, and is also connected with a second container containing a divalent mercury reduction solution through a second peristaltic pump; and the sampling device, the first peristaltic pump, the second peristaltic pump and the mercury measuring device are separately electrically connected with a control circuit. The monitoring method comprises: firstly, the divalent mercury adsorption solution is pumped into the reactor to adsorb the divalent mercury in the fumes, and the mercury concentration measuring device is used to measure the concentration of zero valent mercury in the fumes; secondly, the divalent mercury reduction solution is pumped into the reactor to reduce the divalent mercury to be zero valent mercury, and the concentration obtained by the mercury measuring device at the same time is the concentration of the mercury in the fumes. The monitoring system of the invention is simple in structure, can prevent environment pollution, is highly reliable, achieves on-line automatic continuous monitoring, and improves operation efficiency and measurement accuracy.

AI Technical Summary

Benefits of technology

This technology allows for an improved testing method that uses fewer chemistry than traditional methods while also being more efficient at collecting data from multiple samples without contamination or harmful environmental concerns. It achieves these benefits through controllers with programming sequences on both devices, allowing them to complete their entire cycle quickly even if they shouldn't be doing anything manually. Additionally, it can measure very tiny amounts accurately due to its simplicity and low production cost compared to current systems.

Problems solved by technology

This patented technical problem addressed by this patent relates to improving the performance of mercapture systems that use fossil fuel or other sources of carbon dioxides (CO2) to remove contaminants from exhaust gases released during burning processes like power plants. Current tests involve expensive equipment and dangerous chemicals, making them difficult to operate efficiently at all stages throughout an entire lifecycle without being able to detect any leaks caused by these substances.
