Novel desulfurizing tower

Abstract

The present invention is a new type of desulfurization tower, which includes a tower body, the bottom and top of the tower body are respectively provided with a flue gas inlet and a clean gas outlet, the inside of the tower body is provided with a gas distributor, and the gas distributor is sequentially above the gas distributor. There are four layers of parallel spraying main pipelines, and the spraying main pipelines are provided with spraying pipelines, and the spraying pipelines are connected with nozzles, and a supporting frame is arranged above the uppermost spraying main pipelines, and the supporting frame There are a plurality of rotating impeller groups on the top, and a regular flow demister is arranged above the support frame, and the regular flow demister includes a central fixing device and a surrounding ring-shaped demist chamber, and the ring-shaped demister Filling balls are installed inside the bin, and a tuned mass damper is provided on the tower body at the outlet of the clean gas. The invention not only improves the mist removal efficiency, eliminates fouling and blockage of the mist eliminator, but also avoids wind-induced vibration accidents in towering desulfurization towers, ensuring safe and smooth production.

Description

technical field [0001] The invention relates to the field of flue gas desulfurization, in particular to a novel desulfurization tower. Background technique [0002] Most of the desulfurization towers currently used in my country are traditional structure towers designed and manufactured by China, namely wooden lattice packing, horseshoe pipe overflow, spray nozzle, and ceramic ring defoaming. In daily production and operation, if you are not careful, it will cause liquid entrainment, and the desulfurization liquid will enter the heat exchanger from the outlet of the gas phase pipe through the separator, causing blockage of the heat exchanger tubes. Therefore, preventing desulfurization towers from entraining liquid has become an important research topic. Generally, there are corrugated plate demisters, swirl plate demisters and electrostatic demisters in the desulfurization tower to prevent the phenomenon of gas liquid entrainment, but the baffles and electrostatic plates o...

AI Technical Summary

Problems solved by technology

Generally, there are corrugated plate demisters, swirl plate demisters and electrostatic demisters in the desulfurization tower to prevent the phenomenon of gas liquid entrainment, but the baffles and electrostatic plates of these demisters are in a static state. It is easy to accumulate dust and scale, which may cause the desulfurization system to fail and shut down in serious cases

At the same time, in order to install these demisters in the desulfurization tower, the desulfurization tower will develop towards a higher and higher direction, and the towering desulfurization tower is prone to wind-induced vibration accidents

Wind-induced vibration will not only cause large bending and tilting of the tower body, affecting normal production and operation, but also cause excessive stress on the tower body, form fatigue cracks, and even lead to equipment damage, production stoppage and personnel casualties
