Embodiment Construction

[0028] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0029] like figure 1 As shown, a combined material level measuring device includes a radar level gauge and two tuning fork type level switches arranged in parallel. The radar level gauge is vertically inserted into the middle of the limestone powder silo from the top of the limestone powder silo, and two tuning fork level switches are inserted into the side of the limestone powder silo.

[0030] The radar level gauge includes gauge head 2, extension tube 7 and radar probe 8, gauge head 2 and one end of extension tube 7 are connected, gauge head 2 and extension tube 7 are located at the center above limestone powder bin 1, gauge head 2 One end of the limestone powder bin 1 is fixed with a flange 101, the top of the limestone powder bin 1 is fixed with a first welding flange 51, and the meter head 2 is fixed on the outer wall o...

Abstract

The invention discloses a combined level measuring device. The combined level measuring device comprises a radar level gauge and two tuning fork level switches. The radar level gauge is vertically inserted into the middle of a limestone powder bin from the top of the limestone powder bin. The two tuning fork level switches are inserted into the right sidewall of the limestone powder bin and arranged oppositely in parallel. The combined level measuring device has the advantages that by means of the combined form of the radar level gauge and the two tuning fork level switches, ceaseless monitoring of the level can be ensured, and once any measuring instrument breaks down, the other measuring instruments can continue to monitor the level. Meanwhile, after early warning through the tuning fork level switches, the level can be monitored in real time through the radar level gauge, and then the specific value of the level is obtained.

Description

technical field [0001] The invention relates to the technical field of desulfurization, in particular to a combined material level measuring device. Background technique [0002] In the desulfurization process, limestone-gypsum wet flue gas desulfurization is the mainstream process. In the limestone-gypsum wet flue gas desulfurization process, the limestone slurry in the limestone slurry preparation system is fed into the absorption tower through the slurry supply pump, and the gypsum slurry discharged from the absorption tower is pumped to the dehydration system for dehydration to generate gypsum. The material level parameter of limestone plays a vital role in the operation and control of the whole desulfurization system, so it is necessary to measure the material level of limestone powder bin. However, the existing measuring devices are easily affected by the properties of materials, have unstable performance and inaccurate measurement. Contents of the invention [000...
