PH meter protection device for detecting carbon black flue gas desulfurization slurry

Abstract

The invention discloses a PH meter protection device for detecting carbon black flue gas desulfurization slurry, and relates to a PH meter electrode protection device. The PH meter protection device comprise a tank body, wherein cooling water is introduced into an interlayer of the tank body; a stirrer is arranged in the tank body, a slurry filtering device and an electrode mounting device are arranged in the tank body; a PH meter electrode and a conductivity electrode are fixed on the electrode mounting device; and data measured by means of the two electrodes are accessed to a computer and adisplay of an external DCS control room, the slurry filtering device has filtering holes, a buffer filtering cylinder is arranged outside the electrode mounting device, a cooling water pipe is arranged around the buffer filtering cylinder, a cleaning water access device is arranged above the tank body, and a sewage draining exit is arranged at the bottom part of the tank body. The PH meter protection device is simple in structure, can perform buffering, filtering and cooling on the detected slurry for multiple times, reduces the impact force of the slurry on the PH meter electrode to the maximum extent, lowers the temperature of the detected slurry, prolongs the service life of the PH meter electrode, reduces the production cost of frequent electrode replacement of an enterprise, meanwhile, can detect the conductivity of the detected slurry, and saves manpower and operation time.

Description

technical field [0001] The invention relates to a pH meter electrode protection device, in particular to a pH meter protection device for detecting carbon black flue gas desulfurization slurry. Background technique [0002] Environmental protection is a basic national policy of China. With the development of the national economy and the continuous enhancement of national environmental protection awareness, people have higher and higher requirements for air quality. Carbon black is an important industrial raw material, widely used in rubber products such as tires, as well as dyestuffs, printing, plastics, metallurgy and other industries, and is an indispensable industrial product. The flue gas containing sulfur dioxide will be produced during the production of carbon black. As the country pays more and more attention to energy conservation and emission reduction, the flue gas emission of carbon black enterprises must meet the national requirements to achieve flue gas desulfur...

Problems solved by technology

This protection device is equipped with a cooling water pipe to cool the slurry in the whole box, but it cannot guarantee the stability of the slurry temperature around the pH meter, and the protection device is not equipped with a slurry buffer device, and the slurry has a certain flow rate after entering the box under a certain pressure. It will cause a certain amount of erosion to the pH meter and reduce the life of the electrode. This device does not solve the problem of filtering the slurry. body for cleaning
