Problems solved by technology

However, the γ-ray radiation absorption density meter has limitations in application: for example, a radioactive use license is required; suspended solids and dissolved solids cannot be distinguished; once solid deposits and scaling occur in the pipeline, error signals will appear, etc.

Embodiment Construction

[0009] On the flue gas desulfurization absorption tower or slurry tank, according to the monitoring system design specifications, a plurality of pressure measurement points are evenly distributed along the circumferential direction of the same height, and the pressure signal is sent to the monitoring system through a differential pressure transmitter. These pressure measuring points can be used to measure the density of the absorption tower or slurry tank without adding other detection equipment, and realize pressure measurement and slurry density detection at the same time. The technical solution is: use the existing pressure measurement device and pressure transmitter on the flue gas desulfurization absorption tower or slurry tank, select any one of the measurement point openings to be placed at a low position, and avoid the installation position of the agitator. For the flue gas desulfurization absorption tower or the slurry tank, in order to prevent the solid deposition in ...

Abstract

This invention relates to smoke desulfuration absorptive tower or slurry intensity test method, which set multiple pressure measurement devices with its any measurement device point open position at low level and with remaining positions unchanged to avoid first mixture device and second mixture device fixing position to get slurry intensity according to high difference through formula of difference value equals to intensity times pressure mouth vertical height times weight acceleration to get slurry intensity.

Description

technical field [0001] The invention relates to a detection method for limestone slurry and gypsum slurry density of an absorption tower or a slurry tank used in wet flue gas desulfurization (WFGD) or similar fields, and belongs to the technical field of wet flue gas desulfurization measurement. Background technique [0002] At present, there are many known wet flue gas desulfurization limestone slurry and gypsum slurry density detection devices, the most commonly used is the gamma ray radiation absorption density detection method, the measurement principle is that gamma rays are attenuated after passing through the material, and the attenuation degree depends on the measurement Density of channels and matter. When the measurement channel is constant, the ray absorption is a function of the density of the measured medium. However, the γ-ray radiation absorption density meter has limitations in application: for example, a radioactive use license is required; suspended solids...
