Flow adjusting device and flow adjusting method of slurry conveying pipeline for wet desulphurization process
The invention relates to the technical field of desulfurization treatment, in particular to a flow adjusting device and a flow adjusting method of a slurry conveying pipeline for a wet desulfurization process, and the device comprises desulfurization tower equipment for desulfurizing and generating gypsum in a slurry pond; and the buffer container is connected with the slurry pond through a first pipeline and is used for conveying the slurry in the slurry pond to the buffer container. On the basis of an original structure, only one shut-off valve and the flow limiting orifice plate are additionally arranged on the second pipeline, when the shut-off valve of the main pipeline is closed, a working medium flows only through the flow limiting orifice plate, due to throttling of the flow limiting orifice plate, the pipeline conveying capacity meets the handling capacity of one dewatering device, and the working medium flowing dead zone in front of and behind the shut-off valve is extremely short; the flow limiting orifice plate is installed above the shut-off valve, so that the slurry clogging phenomenon is avoided, the overall manufacturing cost is low, and the larger the slurry conveying amount is, the more investment can be saved.
本发明涉及脱硫处理技术领域，具体而言涉及用于湿法脱硫工艺的浆液输送管道的流量调节装置与流量调节方法，该装置包括：脱硫塔设备，用于脱硫并在浆液池中产生石膏；缓存容器，与浆液池通过第一管道连接，用于将浆液池中的浆液输送至所述缓存容器。本发明在原结构上，仅在第二管道上增加一个关断阀和限流孔板，当主管路的关断阀关闭时，工质仅通过限流孔板流通，由于受到限流孔板节流，管道输送量满足1台脱水设备的处理量，且关断阀前后工质流动死区极短，限流孔板安装在关断阀上方，因此，不会发生浆液淤堵现象，整体造价成本低，且浆液输送量越大，越能节省投资。
