Abstract
The present invention relates to a kind of boiler blower system, including fire grate, the exhaust air box that number arranges upward outlet is installed on the fire grate, fuel combination burns on fire grate；Wherein, pipeline is communicated with the outside of every exhaust air box, pipeline forms secondary airduct, and the other end of pipeline is respectively communicated with frequency conversion type blower fan, frequency conversion type Fan Regulation total blast volume.The present invention can accurately control combustion process.
Description
Technical field
The present invention relates to field of boilers, more particularly, to a kind of boiler blower system.
Background technology
It is general at present by setting a big air compartment upward to burner hearth air blast in fire grate bottom in field of boilers, or
The multiple separating chambers being isolated into from dividing plate are in longitudinal dispersion upward to burner hearth air blast.This blower system is in single combustion of burning
Combustion process is relatively easy to control during coal.But with fuel combination, particularly to save fuel cost, concentrated combustion crops fuel
For the purpose of and when combusting rice hull and coal-fired fuel combination, it is difficult to accurately control combustion process, be mainly manifested in needs according to mixed
The composition for closing fuel carries out the accurate adjustment of air quantity in the vertical, otherwise can cause light in front end, and easily by rice husk
Rice husk is blown away from flue before burning.
The content of the invention
To solve the above problems, the invention provides it is a kind of can accurate adjustment boiler blower system, it is particularly suitable for
Rice husk and coal-fired fuel combination.
The exhaust air box that number arranges upward outlet is installed on the boiler blower system that the present invention is provided, including fire grate, the fire grate,
Fuel combination burns on fire grate；
Wherein, pipeline is communicated with the outside of every exhaust air box, pipeline forms secondary airduct, and the other end of pipeline is respectively communicated with change
Frequency formula blower fan, frequency conversion type Fan Regulation total blast volume.
It is preferred that, control valve is installed, the air quantity of every exhaust air box is adjusted by control valve on every pipeline.
It is preferred that, the air outlet front end of frequency conversion type blower fan sets air main, and the air outlet of air main and frequency conversion type blower fan connects
It is logical, while every secondary airduct is also connected with air main.Between air main is set, air main respectively with frequency conversion type blower fan and secondary airduct
Connection.
It is preferred that, what is be spaced between every secondary airduct be arranged in parallel.
The present invention can accurately control combustion process, and be particularly suitable for use in burning quality very light fuel.
Brief description of the drawings
Fig. 1 is the structural representation of the boiler blower system of one embodiment of the present invention.
Schematic diagrames of the Fig. 2 for present invention application in the boiler
Embodiment
In the description of the invention, it is necessary to illustrate, unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or be integrally connected；Can
To be mechanical connection or electrical connection；Can be joined directly together, can also be indirectly connected to by intermediary, Ke Yishi
The connection of two element internals.For the ordinary skill in the art, with concrete condition above-mentioned term can be understood at this
Concrete meaning in invention.
The present invention is described in detail below in conjunction with the accompanying drawings.
Boiler blower system, including fire grate 1, fire grate 1 are preferably chain furnace grate.Fuel combination falls in chain from feed hopper A
On bar formula fire grate, chain furnace grate can drive and install the upward outlet of number row on equipment or part slip thereon, the fire grate 1
Exhaust air box 2, the vertical fire grate 1 of air outlet of exhaust air box 2 set, and the exhaust air box 2 often arranged is spaced, and two rows are set in the present invention
Exhaust air box 2, certainly can also be more multiple rows of, and specific row can be according to being configured the need for specific, two row's exhaust air boxs 2
It is arranged side by side it is parallel, be set up in parallel, fuel combination burn on fire grate 1, and preferably exhaust air box 2 is bucket shape air compartment, and bucket shape air compartment can
Preferably gather smog or air.
The outside of every exhaust air box 2 is communicated with a pipeline, and pipeline forms what is be spaced between secondary airduct 3, every secondary airduct 3
It is arranged in parallel, in order that the air quantity Uniform Flow in exhaust air box, secondary airduct 3 is arranged on the position in the middle of exhaust air box, every pipeline
Upper installation control valve 4, the regulation of control valve 4 enters the air quantity of secondary airduct 3, and the air quantity into every secondary airduct 3 is as needed
Can freely it adjust, the air outlet front end of frequency conversion type blower fan 5 sets air main 6, the air outlet of air main 6 and frequency conversion type blower fan 5
Connection, while being connected in the every secondary insertion of airduct 3 air main 6 with air main 6, frequency conversion type blower fan 5 is used to adjust total blast volume.Its
In, fuel combination is formed by rice husk and coal-fired flour mixed with adulterants.
Two row's bucket shape air compartment air blast upward, often arrange bucket shape air compartment by multiple independent air compartments for being arranged along fire grate bearing of trend
Composition, so, can accurately be adjusted to air quantity everywhere along fire grate direction.According to substantial amounts of experiment, often row arranges in the present invention
Spacing distance between air compartment is preferably between 30-60 centimetres, and such distance will not make the wind between exhaust air box interact.
The present invention technological process be：Fuel combination falls on chain furnace grate from feed hopper, and fuel combination is on fire grate
Burning, opens frequency conversion type blower fan afterwards, adjusts total blast volume, the intake of secondary airduct is regulated using control valve, afterwards from pair
The blowing that airduct is come in is blown to bucket shape air compartment, the row's bucket shape air compartment air blast upward of left and right two.Frequency conversion type blower fan can be with accurate adjustment
Total blast volume, the air quantity of every exhaust air box is adjusted by control valve.So, can accurately it be adjusted to everywhere along fire grate direction
Air quantity.
Fire grate is also provided in the position of prior art in the present invention, and main improvement of the invention is how to control air quantity
Improvement.
Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
The present invention is described in detail with reference to foregoing embodiments for pipe, it will be understood by those within the art that：Its according to
The technical scheme described in foregoing embodiments can so be modified, or which part or all technical characteristic are entered
Row equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the present invention technology
The scope of scheme.
