Description
Technical field
The present invention relates to a kind of bedding plant, be specifically related to a kind of thermal power generation station-service coal yard of modified node method, be applicable to store jumbo production coal or other mineral.Belong to the ancillary facility technical field of steam power station.
Background technology
Steam power station generates electricity by fire coal, and therefore coal yard is an important component part of steam power station, for the normal operation of power plant provides safeguard.Generally speaking, the coal yard of steam power station all requirement can meet the reserves of 7 ~ 20 days, because the coal storage of coal yard is very large, so floor space is also quite large, the layout of whole power plant is had a great impact, and a large amount of dust severe contamination of coal yard environment around, environmental administration requires also more and more stricter to the environmental practice of coal yard.
Existing coal yard has bar shaped coal yard, silo coal yard and circular coal storage yard, bar shaped coal yard, the coal yard of this kind of form is the most frequently used in steam power station at home, as shown in Figure 1: the centre of coal yard is bucket-wheel stacker reclaimer track, stacker-reclaimer moves above, the two ends of track are defeated coal transfer stations, and track both sides are coal piling places.But this coal yard is high limited owing to piling, and is generally 12m-15m, and being that loose shape is stacked naturally, so coal storage is smaller, then needing to strengthen the floor space of coal yard to increase reserves.Because the dust pollution of this coal yard to periphery is larger, in order to reduce the pollution of dust to environment, additionally environmental practice must be increased, to stop the diffusion of dust, such as build wind-proof dust-suppression net etc. in coal yard surrounding, which adds additional investment, make overall investment larger.
In order to prevent the diffusion of dust, someone adopts totally enclosed type circular coal storage yard, as shown in Figure 2 and Figure 3, this circular coal storage yard can stop the pollution of dust to surrounding enviroment of coal yard, but the complex structure of this coal yard, overall cost are very high, the Investment portion that the investment of this coal yard accounts for whole power plant is sizable, is not suitable for applying.
Summary of the invention
Object of the present invention, the closed-type circular coal yard complex structure in order to overcome prior art, defect that cost is high, a kind of thermal power generation station-service coal yard of modified node method is provided, this coal yard have structure simple, the impact on surrounding enviroment, feature that cost is low can be prevented.
Object of the present invention can be achieved through the following technical solutions:
A kind of thermal power generation station-service coal yard of modified node method, it is characterized in that: comprise rectangle coal yard and be arranged on the fire fighting device established in rectangle coal yard, rectangle coal yard is enclosed by the coal-stopping wall of surrounding and the top cover at top and forms, coal transporting trestle and transfer station is on the ground provided with in the outside of rectangle coal yard, many support columns are provided with in the inside of rectangle coal yard, formed the braced structures supporting top covers by these many support columns, by described braced structures rectangle coal yard is divided into 2-5 across; Be provided with high-order fortune coal yard in the side of rectangle coal yard, described high position fortune coal yard leads directly to rectangle coal yard inner chamber by coal flowing channel, is formed and unload coal into the unloading area of rectangle coal yard; Or described a high position fortune coal yard be positioned at maintain an equal level with the tip height of coal-stopping wall position, directly unload coal into the unloading area of rectangle coal yard.
Further: be provided with low level fortune coal yard in the opposite flank of the high position fortune coal yard of rectangle coal yard, described low level fortune coal yard is positioned at ground, and the coal-stopping wall of low level fortune coal yard side is provided with automobile ingress/egress door.
Further: the ground of described rectangle coal yard has underground coal transporting trestle, this underground coal transporting trestle is communicated with the transfer station be arranged on outside rectangle coal yard.
Further: described underground coal transporting trestle is arranged on the middle part of rectangle coal yard.
Further: be arranged on rectangle coal yard interior support posts and be divided into 25 rows.
Further: the coal-stopping wall being positioned at low level fortune coal yard side is provided with four road automobile ingress/egress doors.
Further: described coal-stopping wall is made up of steel concrete.
1, the present invention due to whole coal yard rectangular, arrange a grade coal wall in coal yard surrounding, top arranges top cover, makes whole coal yard be semi-closed state, effectively can suppress the dust pollution of coal yard, and has effectively saved the construction cost of coal yard; Owing to being provided with many support columns in the inside of rectangle coal yard, formed the braced structures supporting top covers by these many support columns, by described braced structures rectangle coal yard is divided into 25 across, overall structure is firm, and vehicles while passing coal yard is convenient.Therefore, the present invention have structure simple, rationally distributed, easy to use, prevent the pollution of the environment and beneficial effect that building costs is low.
2, the present invention is owing to arranging high-order fortune coal yard in coal yard side, and coal is directly discharged into coal yard by high-order Yun Mei square by coal conveyor, need not arrange coal receiving bunker to unload the coal on coal conveyor; Owing to being provided with on the ground coal transporting trestle and transfer station in the outside of rectangle coal yard, therefore, have the storage capacity improving whole coal yard and convenient from coal yard transport useful for effect.
3, the present invention is owing to arranging low level fortune coal yard in the another side of coal yard, when coal storage is relatively less, the door that can be arranged by the coal-stopping wall place of side, low level Yun Mei square enters coal yard unloading, and tool reduces fine coal and crosses outside the effect of coal-stopping wall when loading and unloading, also have the effect of passageway for fire apparatus.
