Abstract
The invention discloses a coal storage yard of a thermal power plant. The coal storage yard comprises a coal transporting trestle, a transfer station and a fire-fighting device, wherein the coal transporting trestle is arranged outside the coal storage yard, and the fire-fighting device is arranged in the coal storage yard. The coal storage yard is characterized in that the coal storage yard is rectangular, coal bulkheads are arranged around the coal storage yard, a plurality of supporting pillars are arranged in the coal storage yard, a coal storage yard top cover is arranged through the supporting pillars, a high-position coal conveying square is arranged on the side face of the coal storage yard and flushed with the top level of the coal bulkheads, and a coal conveyor enters the coal storage yard to be unloaded through the high-position coal conveying square. The coal storage yard of the thermal power plant is simple in structure and reasonable in layout, the whole coal storage yard is in a semi-closed state, dust pollution of the coal storage yard can be effectively controlled, and construction cost of the coal storage yard is effectively saved. Coal is directly unloaded into the coal storage yard through the high-position coal conveying square, a coal-unloading ditch does not need to be arranged for unloading the coal in the coal conveyor, and besides, the storage volume of the whole coal storage yard is increased.
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 that improves structure, be applicable to store jumbo production with coal or other mineral.The ancillary facility technical field that belongs to the steam power station.
Background technology
The steam power station is to generate electricity by fire coal, so 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 satisfy the reserves of 7～20 days, because the coal storage of coal yard is very large, so floor space is also quite large, layout to whole power plant has a great impact, and the dust severe contamination that coal yard is a large amount of around environment, 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 yard, the bar shaped coal yard, the coal yard of this kind form is the most frequently used in the steam power station at home, as shown in Figure 1: the centre of coal yard is the bucket-wheel stacker reclaimer track, stacker-reclaimer moves in the above, the two ends of track are defeated coal transfer stations, and track both sides are coal piling places.But this coal yard is generally 12m-15m because heap is high limited, and naturally stacks for loose shape, so coal storage is smaller, need strengthen the floor space of coal yard if will increase reserves.Because this coal yard is larger to the dust pollution of periphery, in order to reduce dust to the pollution of environment, must additionally increase environmental practice, to stop the diffusion of dust, such as building wind-proof dust-suppression net etc. in the coal yard surrounding, so just increased additional investment, make whole investment larger.
In order to prevent the diffusion of dust, someone adopts the circular coal yard of totally enclosed type, as shown in Figure 2 and Figure 3, this circle coal yard can stop the dust of coal yard to the pollution of surrounding enviroment, but the complex structure of this coal yard, overall cost are very high, the investment proportion that the investment of this coal yard accounts for whole power plant is sizable, is not suitable for applying.
Summary of the invention
Purpose of the present invention, for the closed-type circular coal yard complex structure that overcomes prior art, the defective that cost is high, a kind of thermal power generation station-service coal yard that improves structure is provided, and that this coal yard has is simple in structure, can prevent the low characteristics of impact, cost on surrounding enviroment.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of thermal power generation station-service coal yard that improves structure, it is characterized in that: comprise the rectangle coal yard and be arranged on the fire fighting device of establishing in the rectangle coal yard, the rectangle coal yard is enclosed by the top cover at the coal-stopping wall of surrounding and top and forms, be provided with coal transporting trestle and transfer station on the ground in the outside of rectangle coal yard, be provided with many support columns in the inside of rectangle coal yard, form the braced structures that supports top covers by these many support columns, by described braced structures with the rectangle coal yard be divided into 2-5 across; Be provided with high-order fortune coal yard in the side of rectangle coal yard, described high-order fortune coal yard leads directly to rectangle coal yard inner chamber, forms and unload coal into the unloading area of rectangle coal yard by coal flowing channel; Perhaps described high-order fortune coal yard is positioned at the position fair with the top height of shelves coal wall, directly unloads coal into the unloading area of rectangle coal yard.
Further: the opposite flank of transporting coal yard in the high position of rectangle coal yard is provided with low level fortune coal yard, and described low level fortune coal yard is positioned at ground, is provided with the automobile ingress/egress door on the coal-stopping wall of low level fortune coal yard side.
Further: the ground of described rectangle coal yard has underground coal transporting trestle, and this underground coal transporting trestle is communicated with the transfer station that is arranged on the rectangle coal yard outside.
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 2-5 row.
Further: the coal-stopping wall that is positioned at low level fortune coal yard one side is provided with four road automobile ingress/egress doors.
Further: described coal-stopping wall is made of steel concrete.
1, the present invention because whole coal yard is rectangular, arranges a grade coal wall in the coal yard surrounding, and top arranges top cover, makes whole coal yard be semi-closed state, can effectively suppress the dust pollution of coal yard, and has effectively saved the construction cost of coal yard; Because the inside at the rectangle coal yard is provided with many support columns, form the braced structures that supports top covers by these many support columns, by described braced structures with the rectangle coal yard be divided into 2-5 across, overall structure is firm, the vehicles while passing coal yard is convenient.Therefore, the present invention have simple in structure, 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 the coal yard side, and coal conveyor is transported the coal square by a high position coal directly is discharged into coal yard, coal receiving bunker need not be set unload coal on coal conveyor; Because the outside at the rectangle coal yard is provided with on the ground coal transporting trestle and transfer station, therefore, have the storage capacity that improves whole coal yard and convenient useful for effect from the coal yard transhipment.
3, the present invention is because the another side at coal yard arranges low level fortune coal yard, when coal storage is relatively less, can transport the door that the shelves coal wall place of coal square side arranges by low level and enter the coal yard unloading, tool reduces fine coal when loading and unloading crosses outside the effect of coal-stopping wall, also has the effect of passageway for fire apparatus.
