Device measuring pH value of absorption tower slurry based on environment-friendly wet desulphurization system

Abstract

The invention provides a device measuring the pH value of absorption tower slurry based on an environment-friendly wet desulphurization system. The device comprises a tank body structure, wherein a pipeline structure is connected with and mounted at the bottom of the tank body structure, and an intercepting structure is arranged on the pipeline structure; a mounting structure is arranged at the bottom end of the tank body structure, and a stabilizing structure is mounted on the mounting structure; a stirring structure is arranged in the stabilizing structure; and the tank body structure comprises a main tank body, a bottom face and an outer connector, the bottom face of the main tank body is of a structure inclining towards one side, the outer connector is arranged at the lowest end of the bottom face in the inclined state, a connecting pipe extending outwards is installed on the outer connector, a positioning ring is arranged on the connecting pipe, and an open groove is formed in the position close to the positioning ring. After slurry flows into a stirring barrel through the intercepting structure, the slurry in the stirring barrel is inevitably shaken and is not stable enough; and since an elastic ring and a bottom spring are additionally arranged between the stirring barrel and a mounting barrel, the slurry in the stirring barrel is more quickly to become static, and subsequent detection is facilitated.

Description

technical field [0001] The invention belongs to the technical field of testing equipment, and more specifically relates to a device for measuring the pH of slurry in an absorption tower based on an environmental protection wet desulfurization system. Background technique [0002] The absorption tower slurry, the pH control of the absorption tower slurry is the core of the limestone-gypsum wet desulfurization reaction, which is affected by the load of the unit, the concentration of sulfur dioxide in the original flue gas, the control value of desulfurization efficiency, and the quality of limestone. Within a certain range, the higher the pH value, the more conducive to the absorption of sulfur dioxide. Increase the desulfurization rate, but when the pH is greater than 5.8, the dissolution rate of Ca2 in limestone will slow down, and the oxidation of SO32- will also be inhibited, which is not conducive to the crystallization of gypsum , on the contrary, the lower the pH, the m...

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a pH measurement device based on the absorption tower slurry of the environmental protection wet desulfurization system, to solve the problem that the existing slurry is relatively viscous and the whole is not uniform enough, and the slurry needs to be fully stirred before detection, but The usual detection needs to be detected in a static state, otherwise the detection will be inaccurate and other phenomena will occur, and the slurry after stirring will shake, and the effect of fast static cannot be achieved.
