Abstract
The utility model discloses a bunker room of a coal-fired power plant. The bunker room comprises two columns of main frame columns, coal grinding machines, a coal supply machine and a coal conveying belt, wherein the coal supply machine is positioned above the coal grinding machines and is communicated with the coal grinding machines; the coal supply belt is positioned above the coal supply machine; the space between the two columns of main frame columns is 13.5 m; an overhauling passage is arranged between the two columns of main frame columns; edges of bunker rooms on two sides of the two columns of main frame columns are also respectively provided with a column of small frame columns; and the coal grinding machines are longitudinally and sequentially arranged between two main frame columns of each column of main frame columns. According to the bunker room, the floor space of the bunker room is reduced, meanwhile, the investment in a coal loading system is not increased because over lifting of elevation of the coal conveying belt layer of the bunker room is ensured to be avoided , one overhauling passage can be shared by the coal grinding machines on the two sides, and the overhauling is more convenient.
Description
Technical field
The utility model belongs to coal-burning power plant's factory building and arranges field, specifically a kind of design form of bunker bay of coal-burning power plant.
Background technology
Along with the fast development of China's economy, the domestic thermal power plant construction has obtained great-leap-forward development.The preferred arrangement in Power Plant Main House zone is saved occupation of land and is reduced investment for the coal-burning power plant, and very important meaning is arranged.Bunker bay is the important component part of main building, and its layout can have influence on the total arrangement of main building, and then has influence on the engineering construction cost.Therefore to fully optimize the main building arrangement in project engineering stage, rationally reduce the engineering construction cost, just must be optimized design to the bunker bay module.
At present, bunker bay is furnished with three kinds of schemes: bunker bay, furnace side bunker bay behind stokehold bunker bay, the stove.Present stage, domestic coal-burning power plant's bunker bay is arranged and is arranged as the master with the stokehold bunker bay; The furnace side coal bunker also begins to use in recent years; Coal bunker is then less behind the stove, only is in the conceptual phase.At present, it is large that stokehold bunker bay arrangement is subjected to the impact of coal pulverizer pattern, appearance and size and maintenance mode to exist the main building floor space, and the pipeline consumption is large, and the factory building zone is vacant between two stoves simultaneously, causes waste, is not most economical scheme therefore.
The side bunker bay is arranged and is referred to that bunker bay is arranged in a side of boiler, the side coal bunker of present stage, equipment (coal pulverizer, feeder, run coal bin) equally all is arranged in the frame construction of bunker bay, but main building dwindles to the distance of boiler and makes pipeline docking port thrust that adverse influence be arranged, and after the main building compact Layout, arrange with routine and to compare to civil engineering and install and brought certain difficulty.Because coal pulverizer, feeder, run coal bin all are arranged in the frame construction, also to satisfy simultaneously satisfying of pipe arrangement, overhaul of the equipments and service condition, therefore cause the bunker bay span to optimize, cause civil engineering costs to increase.
Be subject to the needs of coal pulverizer and maintenance thereof, if the pillar of main frame of bunker bay adopts three row double-spans, 300MW grade coal warehouse receipt span is basically about 18m, coal pulverizer, feeder are arranged in the frame construction, coal pulverizer is arranged in the bottom, the coal pulverizer top is furnished with feeder, feeder passes through its Belt Conveying coal in coal pulverizer, the feeder top is furnished with fortune coal belt, fortune coal belt flows to feeder to coal, not only cause civil engineering costs to increase, and the maintenance inclement condition, the problems such as pipe arrangement difficulty; For satisfying apparatus arrangement, maintenance, need further to increase coal bunker and take up an area, significantly increase civil engineering costs, cause construction investment to increase.
The utility model content
The utility model technical issues that need to address provide and a kind ofly reduce civil engineering costs, save rolled steel dosage, improve simultaneously the bunker bay of operating maintenance environment.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of coal-burning power plant bunker bay, comprise pillar of main frame, coal pulverizer, be positioned at coal pulverizer top and the feeder that is communicated with coal pulverizer, be positioned at the fortune coal belt above the feeder, the pillar of main frame of described bunker bay is two row, spacing between the two row pillar of main frames is 13.5 meters, be access path between the two row pillar of main frames, the edge of the both sides bunker bay of two row pillar of main frames also respectively is provided with a row small frame post; Described coal pulverizer vertically is arranged in order between two pillar of main frames that are arranged on every row pillar of main frame.
Further improvement of the utility model is: laterally be provided with single track between corresponding two coal pulverizers that arrange between described two pillar of main frames.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
The utility model comprises optimizing reducing coal bunker studding distance and layout by the bunker bay innovative design, guarantees simultaneously that bunker bay coal conveyer belt layer absolute altitude excessively do not raise to cause the coaling system increase of investment.
The utility model is by again planning, the coal pulverizer bunker bay is arranged between pillar of main frame, because equipment all is not arranged between the two row pillar of main frames, making bunker bay is the problem that post distance or span have all been broken away from the equipment that is subject in the past (coal pulverizer, feeder etc.), so that the bunker bay volume no longer is subject to the coal pulverizer type selecting, when reducing the bunker bay volume, make the coal pulverizer of two stoves can share an access path, optimized greatly again the maintenance environment, make access path more unobstructed, the Roller of Coal Grinder lifting is more convenient.Bunker bay is also arranged both sides small frame post, satisfies antidetonation and rainproof requirement.
The utility model is to take up an area, save rolled steel dosage, reduction construction investment in order to reduce factory building, and the response national energy-saving reduces discharging calls.By using the utility model, for 300MW grade unit, the bunker bay volume is significantly reduced, reduce approximately about 25% than traditional side coal bunker, reduce to take up an area 1600m
2About, reduce about special steel material use amount 50t (four large pipeline consumptions), reduce cable consumption and cable testing bridge and invest about 5,000,000 yuans, comparable kilowatt of index of main building reduces about 5%.No matter 100MW, 300MW, 600MW, 1000MW grade unit can be used the present invention, can the operation of improvement equipment, the maintenance condition, and can reach again and save civil engineering costs, reduce to take up an area, reduces the effect of investing.
