Problems solved by technology

[0003] However, on the one hand, due to the influence of the gypsum slurry discharge pump, the flow velocity of the gypsum slurry in the main pipe and the vertical branch pipe is unstable, which makes it difficult to control the flow velocity of the gypsum slurry stably
However, because the flow rate of the gypsum slurry cannot be stably controlled and the gypsum slurry is abrasive and easy to clog, the wear of the gypsum slurry on the density meter and the pH meter during the flow is very large, and if the flow rate is reduced in order to reduce wear, the density meter Clogs easily, reducing the life of density and pH meters
On the other hand, due to the high pipe pressure in the pipeline and the high-speed flow of the gypsum slurry in the pipeline, it is difficult to stabilize the flow rate of the gypsum slurry within the required range through manual adjustment, thus increasing the maintenance of on-site equipment. workload

Embodiment Construction

[0018] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements.

[0019] Such as figure 1 As shown, the device for measuring slurry density and pH of the present invention includes a hollow sampling tube assembly, a density meter 10 , a first pH meter 20 and a second pH meter 30 . The hollow sampling tube assembly includes a first branch pipe 41 , a second branch pipe 42 , a third branch pipe 43 , a fourth branch pipe 44 and a fifth branch pipe 45 . The first branch pipe 41 is inclined upwards by 45 degrees and the lower end of the first branch pipe 41 communicates with the lower end of the absorption tower (not shown) and is 1 meter away from the bottom of the absorption tower (not shown), so The first pH meter 20 is inserted into the first branch pipe 41 from the upper end of the first branch pipe 41 . The second branch pipe 42 is horizontally communicated with the first branch pipe...

Abstract

The invention discloses a device for measuring the density and the pH value of slurry. The device comprises an air sampling pipe component, a densitometer, a first pH meter and a second pH meter, wherein the air sampling pipe component comprises a first branch pipe, a second branch pipe, a third branch pipe, a fourth branch pipe and a fifth branch pipe; the lower end of the first branch pipe is connected with the lower end of an absorption tower; the first pH meter is inserted into the first branch pipe; the second branch pipe is horizontally communicated with the first branch pipe; the free end of the second branch pipe is connected with a flushing water pipe; the upper end and lower end of the third branch pipe are respectively communicated with the lower ends of the first branch pipe and the densitometer; the upper end of the densitometer is communicated with the lower end of the fourth branch pipe; the second pH meter is inserted into the fourth branch pipe; the fifth branch pipe is vertically communicated with the fourth branch pipe; and the central lines of the third branch pipe, the fourth branch pipe and the densitometer are positioned on the same straight line and are parallel to the wall of the absorption tower. The device for measuring the density and the pH value of slurry can prolong the service life of the densitometer and the pH meters and reduce the maintenanceworkload of field equipment.

Description

technical field [0001] The invention relates to the field of environmental protection desulfurization, in particular to a method for measuring the density and pH value of gypsum slurry in a desulfurization absorption tower. Background technique [0002] In the environmental protection desulfurization industry, in order to monitor the desulfurization of gypsum slurry, it is usually necessary to use a density meter and a pH meter to monitor the density and pH value of the gypsum slurry in real time. At present, the domestic method for measuring the density and pH value of the gypsum slurry in the desulfurization system is: both the density meter and the pH meter are arranged on the vertical branch pipe of the main pipe where the gypsum slurry discharge pump is located. [0003] However, on the one hand, due to the influence of the gypsum slurry discharge pump, the flow velocity of the gypsum slurry in the main pipe and the vertical branch pipe is unstable, which makes it diffi...
