Detailed description of the invention
Certain thermal power generation corporations, generating set is 2 600,000 kilowatts of Thermal generation unit, and need fire coal about 3,000,000 tons every year, coal yard width 100 meters, length 360 meters, in field, dump height is at about 15 meters, coal yard maximum storage about 200,000 tons.
Build because power plant borders on the sea, affect by sea wind, the dust pollution of coal yard is serious.In addition, the more travel resort of periphery, environmental requirement is higher, for thoroughly administering strong wind dust pollution, existing open type coal yard is turned into the totally-enclosed environmental protection coal bunker of novel wind curtain type.
Wind curtain type totally-enclosed environmental protection coal bunker height 45 meters, width is 100 meters, and length is 360 meters.With reference to Fig. 1, Fig. 2 and Fig. 6, this project forms across agent structure truss 2 by 12 monosymmetric arcs are whole, and agent structure truss 2 and ground base 1 are bolted.Agent structure truss 2 both sides are connected by the longitudinal purlin 10 of three row with middle.Shape of cross section agent structure truss 2 being provided with the first baffle 3, first baffle 3 is wing or water-drop-shaped, the first baffle 3 is arranged the first flow spoiler 4.
With reference to Fig. 3, Fig. 4 and Fig. 5, the spacing of agent structure truss 2 30 meters, between longitudinally drawn several cable wires 6, be covered with net 7 above cable wire, cable wire 6 and net 7 form closes the roofing 10 that feed bin has sunk part 8 and bossing 9.
With reference to Fig. 1, there is the aggregated(particle) structure truss 5 of multiple symmetry between agent structure truss 2 both sides, aggregated(particle) structure truss 5 is provided with the wallboard of ventilative rate 28%, composition feed bin side wall 13.Be provided with between side wall 13 and roofing 10 on second baffle 11, second baffle 11 and second flow spoiler 12 is installed.Described second baffle 11 is arc towards described side wall side, is pointed towards described roofing side.
When wind is by feed bin side wall 13, air-flow part enters in storehouse by the gravity vent of side wall 13, and other air-flows are accelerated by baffle, simultaneously via the vortex generator control separation above baffle, reduces gas-flow resistance, strengthens the viscosity of top of coal bunker air-flow.Simultaneously by rough surface, top, the inside of sunk part 8 can produce low speed rotation air-flow, can produce whirlpool pad effect and Promoting effect, reducing friction resistance, the leeward side of bossing 9 produces inverse nip, thus increases pressure drag, reducing friction resistance, forms eddy current not of uniform size.Form isolated area segmentation internal and external flow field in feed bin top periphery, preferably suppress top updraft, reduce to the volume of air flow outside feed bin significantly, thus reach the object that dust cannot be excessive.
The totally-enclosed environment protection bulk silo venting of wind curtain type is good, cost is low, span is large, efficiently solve bulk cargo stockyard dust pollution problem, solve traditional totally-enclosed feed bin cost high, dust reaches finite concentration and can blast simultaneously, and it is poor to ventilate in storehouse, temperature is high, and operating personnel faces the problem of great occupational health risk, and construction costs saves 40% than traditional totally-enclosed feed bin.
