Embodiment 1
As shown in Figure 1, 2, the present invention has disclosed a kind of circular stockyard veil dust suppression system, this circular stockyard 15 comprises annular barricade 9, be located at rack dome 10 on annular barricade 9, be located at rack dome 10 tops ventilator cowling 14, be located at gate 12 on annular barricade 9, run through the curved top 10 of rack the ribbon conveyer 7 of marching into the arena, run through 8 annular barricades 9 appearance ribbon conveyer 8, be located at the heap feeding equipment 6 in circular stockyard 15; Between annular barricade 9 structures and rack dome 10, be provided with loop vent mouth 13; Its key is: circular stockyard veil dust suppression system comprises the dust suppression system 1, the loop vent mouth veil device 2 that is located at circular stockyard 15 loop vent mouth 13 places that are located at outside circular stockyard 15, is located at circular stockyard 15 12Chu gate, gate veil devices 3, is located at the head sprayer 4 of stacker 11 heads and the afterbody sprayer 5 of stacker 11 afterbodys in heap feeding equipment 6.
Described dust suppression system 1 comprises multi-functional mist machine a, electric-control system b, air compressor machine c, air accumulator d, flow control system e, aqueous vapor connecting line f, the electric tracer heating system etc. made. Multi-functional make mist machine a by suspension in the water at external water source filter out reach veil device require use standard, it has gathered all filters, battery control valve, blowing pipeline valve and pressure sensor. Gas, water after filtering, open or close with pressure, the flow follow procedure control magnetic valve set, are transported to veil device through pipeline, realize spray dust-arrest. Electric-control system b is the control centre of dry fog machine dust suppression system 1, it is connected with circular stockyard heap feeding equipment 6 control signals, automatically receive by stacker 11 remote job signals, attitude signal, trigger dry fog machine dust suppression system 1 and start or stop loop vent mouth veil device 2, gate veil device 3, stacker head sprayer 4, stacker afterbody sprayer 5 and work. Air compressor machine c provides standard source of the gas for dry fog machine dust suppression system 1. The effect of air accumulator d is the compressed air that pre-stored air compressor machine c discharges, and in the time that the capacity of air compressor machine c can not meet dry fog machine a instantaneous displacement and requires, provides the instantaneous gas consumption of drying machine a. Electric tracer heating system g substep is on drying machine a, veil device and air water pipeline, when environment temperature is used during lower than 5 °.
This multi-functional mist machine of making can be multi-functional dry fog machine or Multi-functional water fog machine.
As saving cost mode, micron order dry fog machine can be replaced by water smoke device.
Described loop vent mouth veil device 2 can be divided into many groups and be evenly arranged along 360 ° of loop vent mouths 13 of circular stockyard, and this embodiment arranges 24 groups, and each veil device 2 can independently open, the row of stopping transport. Every group of loop vent mouth veil device 2 can arrange 2 row's shower nozzles, upper row's nozzle layout of sprinkler spout on rack dome 10 is downward, lower row's nozzle layout of sprinkler spout on annular barricade 9 upwards, is the sector region veil wall of 15 ° of radiuses, central angle at loop vent interruption-forming circular stockyard radius when one group of loop vent mouth veil device 2 is worked. Form veil at loop vent mouth 13, prevent dust at loop vent mouth 13 to outdoor escape.
Described gate veil device 3 can be established 3 row's shower nozzles, upper row's nozzle layout of sprinkler is downward in annular barrier wall structure gate 12 top spouts, left bank nozzle layout of sprinkler in annular barrier wall structure gate 12 left part spouts to the right, right row's nozzle layout of sprinkler in annular barrier wall structure gate 12 right part spouts left, when gate veil device 3 is worked at formation rectangular area, gate place veil wall. For gate place form veil, prevent dust at gate to outdoor escape.
Described stacker head sprayer 4 can arrange 4 shower nozzles, is arranged in the stacker 11 head discharge places of circular stockyard heap feeding equipment, directly forms veil when stacker head sprayer 4 is worked in discharging region. Described stacker head sprayer 4, for forming veil in discharging surrounding, is suppressed at product dirt pits by dust.
Described stacker afterbody sprayer 5 can be established 3 shower nozzles, is arranged in the stacker afterbody reloading point material feeding section place of circular stockyard heap feeding equipment, directly forms veil when stacker afterbody sprayer 5 is worked in material feeding region. For forming veil in material feeding place, the dust that suppresses this reloading point produces.
In the time that stacker reclaimer of round stock yard equipment 6 carries out windrow operation, dry fog machine dust suppression system 1 receives the working signal of stacker 11, its electric-control system b triggers stacker 11 head sprayers 4 and stacker 11 afterbody sprayers 5 are worked, material feeding place and discharge pit at stacker 11 form respectively veil, and the dust that suppresses stacker material feeding point and emptying point produces; Electric-control system b is simultaneously according to the position signalling of stacker 11, works according to one group of the procedure triggers relevant position of setting or many groups loop vent mouth veil device 2 of close position, forms the veil wall of certain area at loop vent mouth 13, suppresses dust and leaks; In the time that stacker 11 operating positions arrive or approach circular stockyard gate place, electric-control system b works according to the procedure triggers gate veil device 3 of setting, and forms veil wall at gate place, suppresses dust and leaks. What loop vent mouth veil device group 2 and gate veil device 3 followed that stacker 11 sends close on or away from corresponding the starting or stoping of position signalling. User can arrange amendment veil device working group, spray cycles etc. by PLC.
The present invention makes mist dust suppression principle: the probability maximum of adsorbing, filtering, condense when water fog particle is close with dust granules size. When single air-flow containing grit is walked around droplet, it is relevant with the diameter of droplet that droplet catches in air-flow the probability of grit. When droplet is large, grit is only along with air-flow is walked around droplet and at large catching. When droplet is close with grit footpath, is easier to bump against and catches grit. Micron order dry fog applies just this principle and produces below 5 μ m, and the droplet close with ultra-fine dust size effectively catches dust. Because droplet is trickle, part droplet can be in air evaporation rapidly, make the relative humidity in local space saturated rapidly, the steam after saturated can condense taking grit as core, grit diameter is constantly increased, until whereabouts.
As further saving cost mode, southern user can cancel the electric tracer heating system of making in mist dust suppression system 1.
As further saving cost mode, also can cancel stacker 11 head sprayers 4 and stacker 11 afterbody sprayers 5.
The foregoing is only the preferred embodiment of this method, not in order to limit this method, any amendment of doing within all spirit in this method and principle, be equal to and replace and improvement etc., within all should being included in the protection domain of this method.
