Embodiment 3

[0071] The difference between this embodiment and the second embodiment above is that: from the bottom to the top of the pre-washing tower, a certain height difference △h1, △h2...△hn is set at each interval, and a pressure sensor is set. Based on the measured values ​​of each pressure sensor, it is obtained Different height differences △h1, △h2…△hn correspond to desulfurization slurry pressure differences △P1, △P2…△Pn; and then according to the formula ρ=△P / (g△h), the desulfurization slurry in the prewashing tower is obtained respectively Density ρ1, ρ2...ρn; finally calculate the average value of ρ1, ρ2...ρn, the average value = the density ρ of the desulfurization slurry in the pre-washing tower.

[0072] By measuring the concentration of desulfurization slurry at different heights of the pre-washing tower, the concentration of desulfurization slurry is calculated respectively, and then the average value of each concentration is calculated to further improve the accuracy of t...

Abstract

The invention relates to a method for measuring density of desulfurization slurry in a power plant desulfurization pre-washing tower. The method includes: measuring slurry pressures of the pre-washing tower at different horizontal heights, subtracting the measurements to obtain a slurry pressure difference P corresponding to a difference h of the different horizontal height, and acquiring density Rho of the desulfurization slurry in the pre-washing tower according to the formula: Rho = P/(gh). Also related to is a system for measuring density of desulfurization slurry in a power plant desulfurization pre-washing tower, and the density of desulfurization slurry is measured precisely using the method. The density of desulfurization slurry in the desulfurization pre-washing tower can be measured precisely through the system and method, measuring equipment is simplified, and measuring precision is improved; meanwhile, the system is simple in structure, the method is simple, and the system and method have significant effect and are suitable for popularization and use.

Description

technical field [0001] The invention relates to a method for measuring the density of desulfurization slurry in a desulfurization pre-washing tower of a power plant, and also relates to a measurement system for the density of desulfurization slurry in a desulfurization pre-washing tower of a power plant using the above-mentioned measuring method. Background technique [0002] At present, the method of measuring the slurry density of the desulfurization pre-washing desulfurization tower in the desulfurization system of the power plant generally adopts the method of installing a density meter in the pipeline. The density meter generally adopts the E+H mass flowmeter, and the E+H mass flowmeter belongs to the Coriolis force mass flowmeter, which uses the modulation effect of the fluid mass flow on the oscillation of the vibrating tube, that is, the Coriolis force phenomenon, as the principle. A mass flow meter for the purpose of mass flow measurement. The measurement of the de...
