Description
Technical field
The utility model is related to coal-burning boiler integral arrangement technical fields more particularly to a kind of boiler tail sunk type to arrange
Structure.
Background technology
The rear vertical shaft underlying space of existing routine coal-fired power station boiler is inadequate, needs to add across a denitration steel at rear vertical shaft rear
Structure to De-NO_x, therefore causes arrangement to take up a large area, and is needed in parallel arrangement in the structure of spatial position
It to be connected to denitrification apparatus outward by pipeline, then back into access air preheater etc. below rear vertical shaft with pipeline from denitrification apparatus
Device, convoluted conduit is excessive, and air-flow is unsmooth, and flue gas resistance increases, and energy consumption increases；Due to denitrification apparatus and air preheater
, mounting height is high, and installation, maintenance are inconvenient；It exists simultaneously pressure fan and primary air fan is arranged on ground, fan noise is strong
Up to 80-100 decibel of degree, noise is big to personal and environmental pollution, the noise region be the noise regions current coal-burning power plant Ji great it
One.
Utility model content
The purpose of this utility model is to provide a kind of boiler tail sunk type arrangements, to solve above-mentioned background skill
The problem of art proposes.
A kind of boiler tail sunk type arrangement, including boiler, horizontal flue, rear vertical shaft, denitrification apparatus, air preheat
Device, primary air fan and pressure fan, it is characterised in that：The denitrification apparatus is connected under the heating surface of the rear vertical shaft, described de-
The air preheater is connected below nitre device, and is in serial positional structure；Level ground below the air preheater
Under open up a deep basal pit space, the air preheater lower end enters the deep basal pit space by pipeline, then is connected to described one
Secondary wind turbine, pressure fan and exhaust pass；The supporting steel structure or concrete structure of vertical direction, the support are equipped in the deep basal pit space
The primary air fan and the pressure fan are mounted between steel structure or concrete structure.
Preferably, the deep basal pit top of space is equipped with cover board, and the deep basal pit space is formed confined space.
Preferably, draining pump has been disposed below in the deep basal pit space bottom, and the draining pump is arranged by pipeline to ground
Face.
Due to taking above-mentioned technical solution, the utility model has the beneficial effects that：The depth direction of boiler erects after being located at
Reduce by across a denitration steel construction in well rear；Denitrification apparatus moves to below rear vertical shaft, reduces floor space；Denitrification apparatus and air
Preheater is changed into serial arrangement on spatial position from parallel arrangement, reduces flue length so that flue gas stream is smooth, flue gas
Resistance reduces；The height reduction of denitrification apparatus, air preheater so that installation and repairing is more convenient, uses manpower and material resources sparingly；To give,
Primary air fan takes underground confined space to arrange so that boiler send, 80% or more primary air fan region lower noise；It is comprehensive to reduce
Cost of investment meets industrial innovation direction in terms of necessarily, and market prospects are big.
Description of the drawings
Fig. 1 is a kind of boiler tail sunk type arrangement schematic diagram of the utility model.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Please refer to a kind of boiler tail sunk type arrangement of the description of attached drawing 1, including boiler 1, horizontal flue 2, rear perpendicular
Well 3, denitrification apparatus 4, air preheater 5, primary air fan 6 and pressure fan 7, it is characterised in that：Denitrification apparatus 4 is connected to rear vertical shaft
Under 3 heating surface, across a denitration steel construction is reduced by rear, and denitrification apparatus moves to below rear vertical shaft, reduces floor space, denitration
The lower section of device 4 connects air preheater 5, is changed into serial arrangement from parallel arrangement on spatial position, is filled from rear vertical shaft 3 to denitration
It is in serial positional structure to set 4 and arrive air preheater 5 again all, and tunnel gas flows smoothly；Below air preheater 5 flatly
A deep basal pit space 8 is opened up under face, 5 lower end of air preheater enters deep basal pit space 8 by pipeline, and air preheater 5 moves to
Close to ground, then it is connected to exhaust pass 9；The supporting steel structure or concrete structure 10 of vertical direction, supporting steel structure are equipped in deep basal pit space 8
Or concrete structure 10 is mounted with primary air fan 6 and air-supply for playing a supporting role to deep basal pit space 8 between supporting steel structure or concrete structure 10
Primary air fan 6 and pressure fan 7 are taken the underground space to arrange by machine 7 so that boiler is sent, primary air fan region noise substantially reduces.
Since preferably 8 top of deep basal pit space is equipped with cover board 11, deep basal pit space 8 is formed into confined space, it also can office as needed
Portion opens up maintenance or ventilation hole, and the noise intensity of primary air fan 6 and pressure fan 7, which is initially positioned in underground measured value ratio on ground, pacifies
Measured value when setting reduces by 80% or more, is effectively protected operating environment.
8 bottom of deep basal pit space is mounted with draining pump 12, since deep basal pit space 8 is easy to form ponding, causes to primary
The damage of wind turbine 6 and pressure fan 7, therefore arranged earthward by pipeline using draining pump 12 in 8 bottom of deep basal pit space, discharge ground
Lower ponding.Acoustic material can be also preferably dressed a corpse outside primary air fan 6 and pressure fan 7, reduction noise result in this way is more preferable, comprehensive
Reduced steel structure cost of investment is closed in terms of necessarily, reduces flue resistance, brings and improves power plant's high benefit.
Particular embodiments described above, the technical issues of the utility model is solved, technical solution and advantageous effect into
It has gone further description, it should be understood that the foregoing is merely specific embodiment of the utility model, and has not had to
In limitation the utility model, within the spirit and principle of the utility model, any modification, equivalent substitution and improvements done
Deng should be included within the scope of protection of this utility model.
