Dual-level-meter density measuring device for use at column bottom

Abstract

The invention discloses a dual-level-meter density measuring device for use at a column bottom; the dual-level-meter density measuring device comprises a desulfurizing column; a normal level line is arranged in the desulfurizing column, a diaphragm level meter is arranged on one side of the desulfurizing column, a first upper connection pipe and a first lower connection pipe are connected to the diaphragm level meter, and both the first upper lower connection pipe and the first lower connection pipe are connected right below the normal level line of the desulfurizing column; a magnetic flip level meter is arranged on the other side of the desulfurizing column and is provided with a second upper connection pipe and a second lower connection pipe, the second upper connection pipe is connected above the normal level line of the desulfurizing column, the second lower connection pipe is connected below the normal level line of the desulfurizing column, and both the second lower connection pipe and the first lower connection pipe are positioned on a same horizontal plane. As the dual level meters are arranged at the column bottom, density of magnesium sulfate solution at the bottom of the desulfurizing column can be monitored accurately in time; it is avoided that detection inaccuracy due to errors or failure of individual detection meters leads to blockage of a pipeline in the desulfurizing column due to crystal from too high density of magnesium sulfate solution.

Description

technical field [0001] The invention belongs to the field of coal-fired flue gas desulfurization equipment, and relates to a density meter measuring device, in particular to a double liquid level measuring density measuring device arranged at the bottom of a tower. Background technique [0002] In the traditional magnesium desulfurization process, the lower part of the desulfurization tower is equipped with a liquid storage tank, which is mostly used for temporary storage of magnesium sulfate solution, but the concentration of magnesium sulfate solution in the desulfurization tower is difficult to control, and the concentration is too high to easily lead to liquid crystallization generation of clogging problems. It is very important to know and control the concentration of magnesium sulfite solution in a timely manner, but at present, individual detection instruments sometimes cause deviations in the concentration of magnesium sulfate solution detected due to failure or erro...

[0002] In the traditional magnesium desulfurization process, the lower part of the desulfurization tower is equipped with a liquid storage tank, which is mostly used for temporary storage of magnesium sulfate solution, but the concentration of magnesium sulfate solution in the desulfurization tower is difficult to control, and the concentration is too high to easily lead to liquid crystallization generation of clogging problem

It is very important to know and control the concentration of magnesium sulfite solution in a timely manner, but at present, individual detection instruments sometimes cause deviations in the concentration of magnesium sulfate solution detected due to failure or error, so that the concentration of magnesium sulfate solution cannot be accurately monitored; in order to solve The above defects, now provide a solution
