Embodiment Construction

[0025] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, an anti-blocking two-stage material level measuring device according to an embodiment of the present invention includes two tuning fork material level measuring devices and two compressed air anti-blocking devices.

[0027] The first tuning fork material level measuring device comprises a first retrieving pipeline and a first tuning fork type material level switch 21, the inlet of the first reclaiming pipeline is arranged obliquely relative to the right side wall of the limestone powder bin 1, and is connected to the limestone powder The bin 1 is at 15° in the horizontal direction, the outlet of the first feeding pipeline is fixed with a first welding flange 41, and the first tuning fork type material level switch 21 is set on the first feeding pipeline and connected with the first feeding pip...

Abstract

The invention discloses an anti-blocking double-stage material level measurement device. The anti-blocking double-stage material level measurement device comprises two relatively parallel tuning fork material level measurement devices and two compressed air anti-blocking devices, wherein two tuning fork material level switches are inserted into the right side wall of a limestone powder bin, the two compressed air anti-blocking devices are inserted into the left side wall of the limestone powder bin, and the two compressed air anti-blocking devices and the two tuning fork material level switches are arranged oppositely respectively. The anti-blocking double-stage material level measurement device has the benefits as follows: the measurement device is long in service life, stable in performance, safe and reliable; wall hanging of limestone powder is effectively reduced through inclined arrangement of a material taking pipeline, and the measurement value is more accurate; by means of the arranged tuning fork material level measurement devices, the high material level and the low material level of the limestone powder can be pre-warned; by means of the arranged compressed air anti-blocking devices, false information and misinformation after material accumulation on a level gauge can be effectively avoided, and data reported by the level gauge are more accurate.

Description

technical field [0001] The invention relates to the technical field of desulfurization, in particular to an anti-blocking two-stage 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 i...
