Device for measuring pH value of seriflux in absorption tower

Abstract

The invention relates to a device for measuring the pH value of seriflux in an absorption tower. The device comprises an inclined connector pipe, a sampling valve, a washing three-way valve, electrode three-way valves, pH electrodes, electrode brackets, an overflow valve, a bent pipe, an overflow pipe and a washing water valve, wherein one end of the inclined connector pipe is communicated with the outlet in the lower part of a seriflux tank of the absorption tower, and is upwards obliquelyarranged on the outer side wall of the seriflux tank in the horizontal direction; the other end of the inclined connector pipe, the sampling valve, the washing three-way valve, the electrode three-way valves, the overflow valve and the bent pipe are communicated in sequence and are obliquely arranged in a sealed manner; the other end of the bent pipe is connected with the downwards arranged overflow pipe. The device has low possibility of blocking pipelines, is small in occupied field space, saves space, is simple and feasible in mounting, reduces the production cost of the equipment, is convenient to operate, has low possibility of breaking down, is convenient to operate and maintain, and can be widely applied to measurement of the pH value of seriflux in all types of absorption towers.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to a measuring device for the pH value of slurry in an absorption tower. Background technique [0002] In wet desulfurization systems, pH value is an important control parameter. The pH value directly affects the desulfurization efficiency of the desulfurization system, the dissolution of limestone, the oxidation of sulfite, the crystallization of gypsum, and the corrosion of the desulfurization system. In practical engineering, the optimum pH value is between 5.2 and 5.6. [0003] In the wet desulfurization system, an industrial online pH analyzer is generally used to measure the pH value of the slurry in the slurry pool of the absorption tower. In the original design, the pH value measuring device installed the pH electrode on the gypsum slurry slurry pump pipeline. There are several problems: 1. The flow rate of the slurry pump pipeline is relatively large, and...
