Abstract
The invention discloses a kind of totally-enclosed anti-flour dust overflow skylights of coal bunker, are made of skylight steelframe and resistance dirt ventilator two large divisions, and installation resistance dirt ventilator in dormer two sides is realized and effectively stops that coal dust is excessive in storehouse while coal bunker internal-external heat exchange.Compared with prior art, advantage of the present invention：1. draught area is big, ventilation effect is good；2. effectively preventing coal dust in storehouse excessive while ensureing ventilation effect.3. it makes simply, it is easy for installation.
Description
Technical field
The invention belongs to field of environment protection, and in particular to a kind of totally-enclosed anti-flour dust overflow skylight of coal bunker.
Background technology
At present although traditional totally-enclosed coal bunker solves the problems, such as coal yard dust pollution, but due to coal yard implement it is totally-enclosed after
For confined space, ventilation is poor in storehouse, and stacker-reclaimer takes coal, coal piling to generate a large amount of pollution caused by coal dust in the process；Raw coal was storing
The harmful or inflammable gases such as Cheng Zhonghui volatilizations CH4, H2S；When summer temp is high, coal is easy spontaneous combustion, while dust reaches in storehouse
A certain concentration can explode, and operating personnel faces great occupational health risk.Current totally-enclosed coal bunker is common unpowered logical
Wind ball ventilation effect is poor, although the skylight ventilation effect of open type is good, a large amount of coal dusts can be overflowed by skylight, cause environment dirty
Dye.
Invention content
The object of the invention is intended to provide a kind of a kind of structurally simple, economical practical, anti-flour dust overflow skylight easy for installation.
It can prevent travel fatigue in storehouse excessive in the case where ensureing coal bunker ventilation effect.Fundamentally solves existing closing coal bunker
It should ensure that ventilation will also prevent the problem of flour dust overflow.
In order to achieve the above objectives, the present invention uses following solution:
A kind of anti-flour dust overflow skylight of totally-enclosed coal bunker, it is characterized in that the dormer of rack form, elongated cloth is arranged in top of coal bunker
It sets.It is closed with contour plate at the top of dormer, prevents sleet from entering.The resistance dirt ventilator closing of dormer both sides.Dirt ventilator is hindered by leading
Flowing plate and orifice plate two parts composition.Hole packing free ratio is 28-30%.Mounting guiding board on orifice plate, deflector and orifice plate at
（25°）——（30°）Angle, deflector is while accelerating air-flow, moreover it is possible to stop that sleet enters coal bunker, ensure the work in coal bunker
Industry environment.
Resistance dirt ventilator make full use of aerodynamic principle, when incoming wind by when, deflector generate quickly flowing
Air-flow, orifice plate near zone generate air curtain, when house dust with air-flow reach resistance dirt ventilator near when, due to air curtain
Effect makes indoor and outdoor generate different pressure, and pressure outside is big, and room pressure is small, is realizing ventilation and indoor and outdoor heat exchange
Meanwhile it can effectively stop that coal dust is excessive.
For the present invention in the elongated setting of totally-enclosed top of coal bunker, draught area is big, can effectively ensure to divulge information, and reduces in storehouse
Temperature greatly reduces dust explosion risk, has ensured the safety of operating personnel in storehouse.Meanwhile the present invention can be effectively prevent
Flour dust overflow in storehouse, meets environmental protection inspection and acceptance, protects environment.Ventilation should be ensured again by fundamentally solving totally-enclosed coal bunker
Prevent the problem of flour dust overflow.
The present invention has following advantage compared with the prior art：
1. ventilation effect of the present invention is good, draught area is big.
2. two side elevation of skylight installation resistance dirt ventilator, can prevent coal dust in coal bunker excessive by skylight.
3. mounting guiding board on orifice plate, water conservancy diversion while, which also plays orifice plate tapping, blocks, and can stop external sleet
Into.

Specific implementation mode
Certain power plant's coal yard has had totally-enclosed coal bunker, but since coal yard is implemented totally-enclosed to be confined space afterwards, divulges information in storehouse
Difference, stacker-reclaimer generate a large amount of pollution caused by coal dust during taking coal, coal piling.A large amount of dust is discharged into air by top dormer
In, it can not meet environmental requirement.After anti-flour dust overflow skylight is installed, it both ensure that in storehouse and divulged information, and also effectively prevented dust in storehouse
Excessive, dust-proof effect is good.
Shown in Fig. 1, Fig. 2, Fig. 3, rack form is arranged in top of coal bunker in a kind of totally-enclosed anti-flour dust overflow skylight of coal bunker
Dormer, elongated arrangement.It is closed with contour plate at the top of dormer, prevents sleet from entering.The resistance dirt ventilator closing of dormer both sides.
Shown in Fig. 4, Fig. 5, Fig. 6, resistance dirt ventilator is made of deflector and orifice plate.
Deflector and orifice plate rivet interlacement, orifice plate are connected with skylight steelframe cone tailfiber；Deflector and orifice plate at（ 25°--
30° ）Angle prevents flour dust overflow in storehouse while ensureing to divulge information in storehouse, reaches environmental protection inspection and acceptance standard.
Shown in Fig. 1, rack dormer is that one layer of steel skeleton is protruded at the top of rack, is made of steel rod elements and bolt sphere.Skeleton top
Color steel closing is installed in portion, skeleton and rack wind up it is open between layer, for ventilation in storehouse.Hinder 5 installation of dirt ventilator herein,
Ensure effectively to prevent bisque excessive in the case of available ventilation in storehouse.
Shown in Fig. 6, Fig. 7, Fig. 8, deflector is formed by 0.8mm aluminium plating zinc plate Bending Processings, is fixed on orifice plate with rivet,
Folded plate angle is 110 °, and deflector and orifice plate angle are 25 ° -30 °.Effectively blocking sleet is led into being accelerated through while putting in storage interior
The external air flow of flowing plate enhances ventilation effect inside and outside storehouse.
Shown in Fig. 9, hole packing free ratio is 28-30%.
