Problems solved by technology

[0003] The pH meter is used to monitor the pH value change of the slurry. The pH meter installation box is a special device for fixed installation of pH. The pH meter measures the pH of the slurry flowing through the pH meter installation box, but the existing pH meter installation box takes a long time After work, there will be slurry precipitation at the bottom, so it is necessary to regularly clean the bottom of the pH meter installation box. The maintenance workload is heavy. If it is not cleaned in time, it will affect the accuracy of the pH value measurement of the slurry. meter not working

Embodiment Construction

[0022] Such as Figure 1 to Figure 5 As shown, the pH meter installation box of the present invention includes an outer box body 100 , an inner box body 200 and a liquid inlet pipe 300 .

[0023] The outer box 100 has a cylindrical structure as a whole, with an open top, a cylindrical section 101 on the upper part, and an inverted conical section 102 on the lower part, and a slurry outlet 103 at the bottom of the conical section 102 . In addition, the outer box body 100 also has a box cover 104 that covers the top opening. In order to prevent the case cover 104 from slipping off, an annular locking groove 105 is provided on the edge of the lower surface of the case cover 104 , and the annular locking groove 105 is just buckled on the top opening edge of the outer case body 100 .

[0024] The inner boxes 200 are also cylindrical structures, and the inner boxes 200 are welded and fixed inside the cylindrical section 101 of the outer box 100 through the bracket 201 . The liquid...

Abstract

The invention discloses a pH meter installation case. The pH meter installation case comprises an outer case body, an inner case body fixed in the outer case body, and a liquid inlet pipe extending into the inner case body from the exterior of the outer case body, wherein a case cover is arranged at the top of the outer case body, and a slurry outlet is arranged at the bottom of the outer case body; the inner case body is closed at bottom and opened at top, and an interval space between the inner case body and the outer case body forms an interlayer passageway communicated to the liquid outlet of the outer case body from the top opening of the inner case body; a pH meter installation hole is formed in the case cover and above the inner case body; and a tapered piece with an upward tip is arranged at the bottom of the inner case body, the downward opening of the liquid inlet pipe is just aligned to the tip, and the bottom edge of the tapered piece is close to that of the inner case body. The pH meter installation case has the advantage of preventing slurry from settling at the bottom of the inner case body when flowing through the inner case body.

Description

technical field [0001] The invention belongs to the field of environmental protection desulfurization, and relates to a slurry pH meter of a wet flue gas desulfurization absorption tower, in particular to a pH meter installation box. Background technique [0002] Wet flue gas desulfurization in coal-fired power plants is currently the desulfurization technology with the highest desulfurization rate and the most widely used. This technology uses limestone slurry (made by grinding limestone with water) as a desulfurizer, and sprays and washes the sulfur dioxide contained in the flue gas in the absorption tower (chemical reaction device) to make the SO2 in the flue gas 2 The reaction produces CaSO 4 , the key point of this reaction is Ca 2+ The formation of , while the formation of H + The concentration of the limestone is related to the pH value of the slurry. The optimal range is 5.8-6.2, which is most conducive to the decomposition of the limestone slurry to form Ca 2+ T...
