The nozzle 61 is Fine-fog nozzle.
The present invention on source by administering dust, and for administering below 10 μm of particle diameter, particularly respirable dust is imitated
Fruit is preferable, is completely suitable for weather conditions in the region of Guizhou and administers the dust that grey storehouse inorganization spreads.Regulation effect is entirely capable of
Enough reach GB13223-2011《Fossil-fuel power plant atmospheric pollutant emission standard》、GB3095-2012《Ambient air quality》、
GBZ2.1-2007《People's Republic of China's Occupational sanitary standard workplace harmful factors occupational exposure limit the 1st
Point:Chemical noxious factor》Regulation.Grey storehouse both efficiently, thoroughly can have been administered in ash of removing stage makeup and costume from source using micro- mist dust suppression technology
Dust caused by process, realize the dust removing effects that traditional deduster is unable to reach, it is ensured that work production scene dust emission concentration
Reach setting, substantially improve current dust pollution status, can be that site operation personnel creates, provides good building ring
Border, the equipment safety stable operation in respective regions can be also ensured, reduce equipment fault.The work of maintainer is also reduced simultaneously
Measure, greatly facilitate maintainer's regular maintenance, save the energy.
According to the Dust Characteristics below most of 10 μm of coal dust, using formed objects are identical with dust size, motion state
Micro- mist below 10 μm of identical sinks after condensing increase quality with dust, and is unloaded in canning cart telescopic head discharge port with bulk vehicle
Check apron is arranged in material mouth region.Dust and dry fog change direction decline after check apron is collided after condensing.
Can be with caused coal dust in the operation process of effective and thorough solution coal-fired power plant's ash storehouse using suppressing dust with dry mist system
Pollution problem.Height, not only dust suppression efficiency high, automaticity, and stable, easy maintenance, maintenance cost are low.
For the characteristic of caused coal dust, live pollution situation, service condition, improvement require in grey storehouse operation process, adopt
It is most preferable effective measures and at first to administer caused pollution caused by coal dust in grey storehouse operation process with the micro- mist dust suppression technology of two-fluid
The technology entered.At present, it is also originality and uniqueness in terms of the technology coal-fired power plant ash storehouse coal dust control.The micro- mist suppression of two-fluid
Dirt system is the form using gas-vapor mix, compressed air and water is mixed into steam atomizing nozzle in proportion, by compressed air
Accelerated after washing the spring of atomizer open and crushed the concussion room of water inlet nozzle, uniformly, using accelerating gas
The water smoke of grain diameter≤10 μm after will be broken sprays from nozzle, forms close and dense " mist pond ", suppresses space from source
Interior coal dust
Grey storehouse elimination of dust contamination thinking:
According to the Dust Characteristics below most of 10 μm of coal dust, using formed objects are identical with dust size, motion state
Micro- mist below 10 μm of identical sinks after condensing increase quality with dust, and is unloaded in canning cart telescopic head discharge port with bulk vehicle
Check apron is arranged in material mouth region.Dust and dry fog change direction decline after check apron is collided after condensing.In grey storehouse wagon spout column surrounding
Check apron is set, and check apron height is highly higher 100mm than automobile, and particular location determines according to on-site actual situations.
Using automatic curtain, closed in tank car or bulk vehicle with roof interplanar, prevent dust escape diffusion.In roller shutter
A number of Fine-fog nozzle module is arranged around discharge port, is caught using ultrasonic dry fog, declined after condensation dust.Work as operator
When member starts discharge port, automatic curtain is begun to decline, and makes to put gray area one closed environment of formation.When discharge port starts 2 seconds
The nozzle around discharge port starts to spray afterwards.When entrucking is expired soon (operations staff can be observed by central station of floating dock), unload
Material mouth stops putting ash, stops spraying after roller shutter rises after being delayed 5 seconds, spraying postpones 4 seconds, so as to reach dust suppression purpose.Work as entrucking
After, the dust for being scattered in ground has operations staff to rinse immediately, prevents occurring reentrainment of dust when vehicle from passing through.According to
Cloud physics principle, rainfall is formed by the nuclei of condensation of dust;Generation is mutually collided according to ultrasonic dry fog principle, same particle size simultaneously
It is high to condense probability, and is collided by check apron, is agglomerating, sedimentation, micro- mist plays a part of catching dust in whole process.
Loading spout discharge port is changed, discharge port uses the loading spout discharge port supporting with dusting fan.In grey storehouse second floor cloth
Dusting fan is put, dust caused by whereabouts and negative pressure are let out to top discharge duct, form it into a circulatory system.
1) grey storehouse in discharging due to having a large amount of dust caused by height fall and negative pressure.
2) loading spout discharge port is changed, discharge port uses and the supporting loading spout discharge port of dusting fan.
3) dusting fan is arranged in grey storehouse second floor, dust caused by whereabouts and negative pressure is let out to top discharge duct, make it
Form a circulatory system.
4. observation ward
Dust overflows during to prevent from putting ash, and operations staff will observe at any time puts grey height and put ash to stop discharge port, is
Run observer and design an observation ward.Observation ward is arranged in the grey vacant position of storehouse second floor, and there is monitoring system inside, runs people
Member can be shown with wagon box material position by screen to judge to put grey height.Camera is arranged on top directly over each discharge port,
The each discharge port of observable puts grey height.
1) to be overflowed for dust when preventing from putting ash, operations staff will observe at any time puts grey height and puts ash to stop discharge port,
For operation, observer designs an observation ward.
2) observation ward is arranged in the grey vacant position of storehouse second floor, and there is monitoring system inside, and operations staff can be shown by screen
