Description
Technical field
The present invention relates to environmental technology field, more particularly to cleaner, and in particular to it is tight that one kind is used for dust collector ash hopper
The automatic safety signal valve for putting ash under weight dust stratification state.
Background technology
Showing for the of short duration dust stratification of ash bucket occurs often because of ash discharge failure in the dust collector ash hopper that thermal power plant is equipped with often
As this belongs to normal phenomenon, as long as general dust stratification is in the grey capacity of storage that dust collector ash hopper allows, and dust stratification duration correspondence is extensive
In the time range of multiple normal ash disposal, deduster would not be caused harm.Therefore dust collector ash hopper dust stratification causes to endanger to deduster
Harmful case, is entirely because failture evacuation not in time, makes dust stratification inside dust collector ash hopper exceed deduster design permission
Storage capacity.
It is domestic repeatedly to occur the security incident caused by the serious dust stratification of dust collector ash hopper.Such as：Hubei Pu in 2005
No. 2 electric cleaner " 1.1 " total collapse accidents of boundary Power Plant No.1 unit (300,000 kilowatts)；The second thermoelectricity of the packet header of the Inner Mongol in 2005
Electric field " 3.20 " the ash bucket total collapse accident of factory No. 2 units (200,000 kilowatts) electric cleaner one；Inner Mongol Huo Mei groups in 2005
No. 3 unit " 4.9 " ash bucket case accidents of one phase of power plant for self-supply of Hong Junlv electricity companies；The grey hair of 2006 time electricity international Anhui Chizhou City nine
Electric No. 2 unit electric cleaner " 3.14 " cave-in accidents of Co., Ltd；The safe and sound Iron And Steel Co., Ltd in Tangshan " 9.23 " electricity is removed within 2014
Dirt device ash bucket cave-in accident etc..Above-mentioned its inducement of startling accident can all be attributed to the accident dust stratification of deduster and not and
When deashing.
Current domestic thermal power plant deduster judges whether the technological means of dust stratification mainly has three aspects for inside：Deduster ash
The high charge level switch that struggles against judges；Deduster ash disposal system operational factor indirect discrimination；Measure checking is disassembled in maintenance.
The factor of ash disposal system operational factor indirect discrimination influence is a lot, and needs the comparison of longtime running parameter, has
There is very big hysteresis quality, it is impossible to find dust stratification hidden danger in time.The feelings that measure checking often has occurred and that in accident are disassembled in maintenance
Under condition, that takes has the interim measure of certain risk and damaging, is not the technical measures that equipment is normally run.So,
At present in the industry it is main choose ash bucket high charge level switch judge measure judge inside deduster whether dust stratification.
Generally judge to coordinate artificial accident cinerary device to handle inside deduster seriously using high charge level switch at this stage
Dust stratification failure, the premise of such a mode is will be using ash bucket high charge level switching signal as operation foundation, if high charge level switch letter
Number go wrong, then this mode just can not normal work.In addition, when high charge level switching signal fails, not only can not and
When process accident hidden danger, accident potential can not be judged whether in time by also resulting in staff, and this is also to cause domestic hair
The key technology factor of the serious dust stratification accident of raw deduster.
As shown in figure 1, existing dust collector ash hopper when on ash bucket high charge level switch 01 alarm when, it is necessary to which ash bucket is opened manually
The urgent cinerary device 02 of bottom accident, carries out urgent ash discharge, if carry out accident promptly puts ash and fully relies on high charge level switch 01
Single source signal.
In ash bucket high charge level switch type selecting, because radio frequency admittance material level indicator is relatively economical, reliable, therefore, general
Time design selection use radio frequency admittance material level indicator.Theoretically, radio frequency admittance material level indicator is used in design
Advanced anti-adhesive circuit, using the measurement of many reference amounts, wherein by using exchange phase demodulation sampler, being solved from mathematical theory
Bridging problem on switch.But, in dust collector ash hopper in adverse circumstances, radio frequency admittance material level indicator still goes out unavoidably
Existing false alarm and damage, exactly because also radio frequency admittance material level indicator false alarm takes place frequently in actual applications, it is easy to operation
Administrative staff produce the misleading in understanding.In addition, radio frequency admittance level-sensing device is needed by having using debugging is preceding needed during debugging
Grey and ashless two states, ability accurate calibration level-sensing device, so, in deduster ash disposal system existing defects, such as ash disposal
When design conveying capacity is not enough, deduster air flow method is uneven, it will make the presence of very big wind in ash disposal system running
Dangerous hidden danger.If deduster is run in the case where there is hidden danger for a long time, maintainer can not in time have found and exclude again to ask
Topic, the accumulation of problem for a long time finally will result in serious harm.The country has many dedusters serious product occur going into operation in 1 year
Grey failure, is exactly mainly caused by above-mentioned reason.
With the constantly improve of passive nucleon material-level measure technological means, passive nuclear level sensing device has obtained more and more wider
General use.But, for passive nuclear level sensing device, equally there is also the possibility for breaking down and failing, in addition, passive nucleon
Test and checking that level-sensing device does not also pass through under the state of emergency, so, even if being led using passive nuclear level sensing device instead of radio frequency
Stuff level switch of receiving can not avoid deduster to occur serious dust stratification harm completely.
Thus, ash bucket dust stratification can be judged accurately, conveniently, reliably, in time by how realizing, and safe and simple, effective
The serious dust stratification accident potential of processing deduster is the important topic of urgent need to resolve in the industry.
