Detailed Description
A device for measuring the level of the dust removed by a dust remover, as shown in figure 1, the device for measuring the level of the dust removed by the dust remover comprises a dust remover ash bin 1, the dust remover ash bin is arranged at the lower end of a dust removal box body 2, industrial flue gas 3 is sucked into the dust removal box body 2 under the action of an induced draft fan 4, the flue gas is discharged from a chimney 5 after passing through a filter screen in the dust removal box body, the separated particles blocked by the filter screen can fall into the dust remover ash bin 1 at the lower end, as the level of the measured dust, the side wall of the dust remover ash bin 1 is vertically arranged at intervals to a plurality of vent pipes 6, the level is set according to the display requirement, one end of the vent pipe extends into the side wall of the dust remover ash bin 1 and is arranged in the inner cavity of the dust remover ash bin, the other end of the vent pipe at the outer side wall of the dust remover ash bin is provided with a pressure sensor 7, one gas pipe 8 is connected with the middle section of the gas pipe 6 at the outer side wall of the dust remover ash bin, and is connected with a constant pressure source 9, the pressure sensor signal output connects the ash material level display controller 10, after the constant pressure air source starts, when the vent pipe outlet of the dust remover ash bin inner cavity is not blocked, the pressure sensor has no pressure signal change output, and when the upper vent pipe outlet and the lower vent pipe outlet of the dust remover ash bin inner cavity are buried in sequence by falling dust particles and blocked, the pressure sensor has pressure signal change output, thereby realizing the measurement of the ash material level in the dust remover ash bin, the bottom 101 of the dust remover ash bin is provided with an ash outlet, and only a gate 11 is arranged on the ash outlet.
In order to prevent the outlet of the vent pipe from being blocked by dust particles to influence the accuracy of measurement, the vent pipe outlet 601 extending into the inner cavity of the dust bin of the dust remover is provided with a steel wire mesh for preventing particles from being clamped into the outlet of the vent pipe. Meanwhile, the vent pipe extending into the inner cavity of the dust bin of the dust remover is bent to enable the outlet of the vent pipe to be arranged downwards in an inclined mode.
In the examples: the diameter of the vent pipe is 10mm to 20mm, and the pressure of the constant pressure air source is 0.1kg/cm2。
In this embodiment: the two vent pipes are respectively arranged at the bottom end side of the dust collector ash bin and the top end side of the dust collector ash bin. Wherein: the distance between the vent pipe arranged at the bottom end side of the dust collector ash bin and the ash discharge port at the bottom end of the dust collector ash bin is 10 cm; the distance between the vent pipe arranged at the top end side of the dust collector ash bin and the top dust collection box body is 20 cm. When the vent pipe on the top end side of the dust remover ash bin blocks the signal sent by the pressure sensor, the dust remover ash bin is informed of the need of cleaning the dust remover ash bin, and after the dust remover ash bin is cleaned, the vent pipe on the bottom end side of the dust remover ash bin still blocks the signal sent by the pressure sensor and informs an operator that the dust remover ash bin is not cleaned.
During installation and debugging, the parameters of the pressure sensor can be adjusted, and the parameters (pressure critical value) of the pressure sensor are adjusted and set according to the specific gravity of the material and the size of the material bin. Inside the breather pipe is installed as material level steel construction pipe fitting, its head portion inserted to the ash bin, pipe fitting fixing device was fixed with ash bin external connection, when the dust material was higher than the breather pipe material level, the resistance rose after the dust granule that the breather pipe export was fallen into was buried and is blockked, and pressure sensor received pressure and is higher than the critical value, and the sensor feedback has material signal, and the red colour is shown to the 10 warning lights of grey material level display controller. When the material is lower than the material level, the resistance is reduced, the pressure sensor receives a pressure lower than a critical value, the pressure sensor feeds back a material-free signal, and the warning lamp of the ash material level display controller 10 displays blue.
The device for measuring the dust removal ash material level of the dust remover in the embodiment has the advantages of simple structure, convenience in disassembly and convenience in maintenance. Only one ventilation pipe fitting is arranged in the bin, so that the installation, the disassembly and the maintenance are very convenient. And, long service life, the general operational environment of dust remover all is comparatively abominable, receives factors influence such as high temperature, corruption in the ash bin, and the inside part of traditional charge level indicator installation in ash bin is the easy loss extremely to influence charge level indicator whole life.
