Technical field
The invention belongs to removing dust and clearing ash equipment technical field, the ash bucket monitoring material position of more particularly to a kind of accumulatingdust is with meeting an urgent need
Ash-discharging device and method.
Background technology
At present, waste heat boiler due to the monitoring of grey position it is not in place, often result in each ash bucket all high grey positions, eventually lead to
Afterheat boiler system is unstable or failure is had to shutdown maintenance.In normal operation, the height of grey position is ash disposal in ash bucket
Operations staff implements the important information of tracking, and ash disposal personnel need to control the material position in ash bucket, in addition need whether observation ash bucket is located
In the ash buckets failure such as dust stratification, dust, fluffy ash in normal operating conditions, such as ash bucket.
With the continuous maturation of domestic cogeneration technology, for waste heat boiler operation and maintenance requirement also increasingly
Height, the degree of automation of cogeneration are also constantly improving, but still remain operations staff for boiler in many projects
The inadequate situation of the attention degree of deashing, often has ash bucket or even the excessive situation of dust deposit in flue occurs, serious threat to pot
The safety of stove operation.
Invention content
In order to overcome shortcoming and deficiency in the prior art, the present invention provides a kind of ash bucket material position prisons of accumulatingdust
Survey and emergent ash-discharging device and method, can not only realize ash bucket monitoring material position, can also realize that ash bucket ash position reaches setting
Automatic ash-discharging emergency processing when high-order.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of ash bucket monitoring material position of accumulatingdust and emergent ash-discharging device, including conventional discharge system, bypass ash poking system
System, automatic ash-discharging system and emergency alert system;The routine discharge system is connected at the lower section ash hole of ash bucket, is routinely unloaded
Material system includes being located at the top of discharger by the flat gate valve and discharger of take over connection, flat gate valve;The bypass ash poking
System includes that bypass ash poking mouth, thermocouple, bypass are emergent to put grey bend pipe, gate valve and bypass is emergent puts ash and take over, and bypass is emergent
Put grey bend pipe, gate valve and bypass it is emergent put ash and take over be sequentially connected from top to bottom;Bypass is emergent to put grey bend pipe and is being located at ash bucket just
The side of lower section, bypass ash poking mouth are located at the emergent oblique upper end for putting grey bend pipe of bypass and positioned at the lower parts of ash bucket, and thermocouple is located at
The routine discharge system takes over inlet;The automatic ash-discharging system is connected to the side below ash bucket, automatic ash-discharging system
System includes interface, flap valve and automatic ash-discharging and takes over, and flap valve is located at the intersection of ash bucket and interface, and automatic ash-discharging is connect under interface
It takes over;The emergency alert system is located at the inside of ash bucket, and emergency alert system includes level-sensing device, probe and protection board, protection
Plate is located at the top of probe;The routine discharge system, bypass the thermocouple of ash poking system, automatic ash-discharging system flap valve,
The horizontally disposed height of the probe of emergency alert system is incremented by successively.
Further, the conventional discharge system, bypass ash poking system, automatic ash-discharging system and emergency alert system is each
From central axes and ash bucket in center line be arranged on same plane.
Further, the bypass ash poking mouth is set at the height H1 of the ash hole immediately below ash bucket;It is described to answer
Anxious warning device is set to below the center line of exhaust pass at height H2.
Further, the flat gate valve is manual one-way fashion;Discharger is Star-like unloader.The thermocouple is E types
Thermocouple.The flap valve is gravity flap valve.The material position is calculated as radio frequency admittance level-sensing device;It pops one's head in and pops one's head in for bar type.It is described
Bypass is emergent, and to put grey bend pipe and the angle of vertical direction be 120~140 °.
Using the method for the ash bucket monitoring material position and emergent ash-discharging device of a kind of accumulatingdust, process is as follows:It is remaining
Heat boiler at runtime, it is described routine discharge system open, the dust fallen into ash bucket out of waste heat boiler by take over via
Discharger is constantly discharged;When the temperature that the thermocouple of the bypass ash poking system detects is less than setting range, then institute is opened
The emergent gate valve put ash and taken over of bypass is stated, dust stratification is made to be put during ash takes over from bypass is emergent by the bypass ash poking mouth ash poking
Discharge;If dust stratification cannot be solved effectively in ash bucket, and waste heat boiler continues to run with, and ash bucket dust stratification reaches the automatic ash-discharging system
When at the flap valve of system, flap valve automatically turns under material gravity effect, meet an urgent need and unloads ash;If above-mentioned each system is still not
Can solve the problems, such as to unload it is grey, in ash bucket dust stratification arrival emergency altitude and trigger the emergency alert system, then shut down waste heat boiler, treat
Waste heat boiler can be just restarted after dust stratification is cleaned out in ash bucket.
Further, when the conventional discharge system breaks down, then the flat gate valve on conventional discharge system is closed,
Open simultaneously the bypass it is emergent put the gate valve that ash is taken over and meet an urgent need unload ash;Institute is then turned on after waiting for conventional discharge system reparation
It states flat gate valve and closes the emergent gate valve put ash and taken over of bypass.
Part dust into waste heat boiler entrained by flue gas falls into ash bucket and is discharged via the ash-discharging device of the present invention,
He takes away dust with flue gas via exhaust pass.
Apparatus of the present invention can not only effectively monitor ash bucket material position by the way that four systems are be combined with each other, can also be in spy
Automatic emergency unloads ash in the case of different, realize waste heat boiler ash bucket it is safe and stable, efficiently unload ash, manpower money is greatly saved
Source.
The conventional discharge system, bypass ash poking system, automatic ash-discharging system and emergency alert system four of apparatus of the present invention
System is set from top to bottom successively in position, and each system coordinates cooperation during ash is unloaded, all linked with one another, and design is very skilful
It is wonderful, it ensure that device is run steadily in the long term:If dust stratification situation occurs in conventional discharge system, bypass ash poking system, which is opened, to be used;
When bypass ash poking system does not play effect, automatic ash-discharging system begins to use;When automatic ash-discharging system does not play effect,
When dust stratification reaches the alarm state of emergency alert system, emergency alert system plays a role.
In addition, each system structure simplicity of apparatus of the present invention is compact, it is easily installed and dismantles;Plant automation operation is horizontal
Also higher reduces the execute-in-place difficulty of worker.
