Abstract

The invention relates to the technical field of thermal power plants and discloses a pH value integrated measurement device. The device comprises a desulfurization tower, a tank body, a tapered chamber, a stirrer, a pH meter probe, a washing water pipe, a washing nozzle, a sampling connection piece and an overflow pipe. The bottom of the tank body is provided with the tapered chamber which is communicated with the tank body and has a large upper end and a small lower end. The stirrer is fixedly installed in the tank body. The pH meter probe is fixedly installed on the inner wall of the top of the tank body. The washing nozzle for washing the pH meter probe is fixedly installed under the pH meter probe. The obliquely upward sampling connection piece is arranged between the bottom of the desulfurization tower and the lower part of tank body and is communicated with the bottom of the desulfurization tower and the lower part of tank body. The overflow pipe is fixedly connected to the upper part of the tank body and the desulfurization tower and is located between the upper part of the tank body and the desulfurization tower. The device has a reasonable and compact structure, is convenient for use, prolongs a service life of the pH meter probe, improves pH meter probe washing effects and solves the problem that the pH meter probe produces scale and a part of blind corners of the tank body are not washed for a long time and produce scale so that the detected pH value linear distortion or measurement delaying is produced.

Description

technical field [0001] The invention relates to the technical field of pH measurement devices for thermal power plants, and relates to a pH value integrated measurement device. Background technique [0002] In the wet desulfurization system, the 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 actual engineering, pH The best value is between 5.2 and 5.6. The pH value of the slurry in the desulfurization absorption tower is an important monitoring index for the operation of the desulfurization system. If the pH value of the slurry is too low, the sulfur dioxide absorption effect will be poor and the desulfurization efficiency will be low; if the pH value is too high , the limestone utilization rate and gypsum purity are low, which is not conducive to the...
