Universal limestone pipeline distributor

Abstract

The invention relates to a universal limestone pipeline distributor, which includes an inlet flange, a cylinder body, a top cover and an outlet flange. The body is a cylindrical structure, the lower cylinder is a frustum-shaped structure, the bottom of the lower cylinder is provided with an inlet pipe, the inlet flange is fixed on the inlet pipe, and the outer wall of the upper cylinder is provided with a first outlet pipe in a clockwise direction. , the second outlet pipe, the third outlet pipe and the fourth outlet pipe, an outlet flange is respectively fixed on the first outlet pipe, the second outlet pipe, the third outlet pipe and the fourth outlet pipe, and the top cover is detachable Fixed on the top of the upper cylinder, it can realize the pipeline from one to two, from one to three, and from one to four at one time; after the distribution of pipelines, the layout is flexible, and the limitation of site conditions is small, and the multi-pipelines can be evenly fed.

Description

technical field [0001] The invention relates to a universal limestone pipeline distributor, which is applied to the limestone conveying process pipeline of the dry desulfurization system in the furnace of a CFB unit. Background technique [0002] Circulating fluidized bed (CFB) boiler is a clean combustion technology that develops rapidly and is widely used. It can achieve low SO2 emission by adding limestone to the furnace. Since CFB boilers can achieve clean combustion of fuel, they have been rapidly developed around the world. At present, the research level of CFB technology in China is also in the forefront of the world. [0003] One of the great advantages of CFB boiler technology is the desulfurization in the furnace by spraying limestone powder directly into the furnace. Compared with conventional pulverized coal boiler tail flue gas desulfurization (FGD), this desulfurization system is simple, occupies a small area, and the system is stable and reliable in operation...

AI Technical Summary

Problems solved by technology

For a single pipeline to enter multiple boiler furnace inlets, it can only be realized through multiple pipeline distributions, which will inevitably result in many pipeline elbows, large pipeline resistance, and difficult layout.

When the number of boiler furnace inlets is odd, it is difficult to achieve uniform feeding of pipelines
