Abstract

The invention discloses a regulating valve. The regulating valve comprises an adjusting rod and a plurality of butterfly valves. Each butterfly valve comprises a valve body, a valve plate and a connecting rod sleeve. A valve adjusting rod is sleeved with the connecting rod sleeve and is fixedly connected with the connecting rod sleeve. The butterfly valves are connected in series with each other through the valve adjusting rod, and the two ends of the valve adjusting rod both extend out of the connecting rod sleeve. The invention discloses a desulfurizing tower. The desulfurizing tower comprises the regulating valve. The regulating valve is arranged at the end, far away from a spraying layer, of a pipe bundle demister, one end of the valve body is connected with demisting pipes, and the two ends of the valve adjusting rod are connected with a main body. The valve body is mounted in a plurality of pipelines connected in parallel, the multiple pipelines in parallel can be opened and closed at the same time, and meanwhile, the regulating valve has the beneficial effects of being simple in structure and low in cost; and when the working condition load fluctuates, the amount of flue gasin the remaining demisting pipes reaches the designed flow rate range by closing part of the demisting pipes through the regulating valve, so that the purpose of controlling the flow rate of the pipebundle demister is achieved, and the demisting and dust removing efficiency is improved.

Description

technical field [0001] The invention relates to the field of valves and desulfurization towers, in particular to a regulating valve and a desulfurization tower. Background technique [0002] The valve is a pipeline accessory used to open and close the pipeline, control the flow direction, adjust and control the parameters of the conveying medium. When the current valves are in use, each valve is installed on one pipeline. When there are many pipelines, the valves on each pipeline need to be adjusted separately, which is troublesome to adjust. At present, it can only be electrically connected to the controller by using a solenoid valve. In order to realize batch adjustment of valves, the cost is high. [0003] Tube bundle demisters are often used in desulfurization towers to deal with smoke and dust. The necessary condition for tube bundle demisters to achieve ultra-low emissions is sufficient flue gas volume under working conditions, so that the flue gas has a faster flow r...
