If distance.In drying system running, because the laying spacing of first point of wind branch pipe 2 is larger, therefore has part and be located at
Region between two adjacent first point of wind branch pipes 2 can not access sufficient drying, therefore, can be run in drying system
During, control divides cloth set direction position adjustment of the airduct air-distribution device along multiple first point of wind branch pipe 2 so that divides airduct cloth wind
Region between the two first point of wind branch pipes 2 adjacent before being adjusted to of the position of first point of wind branch pipe 2 of device, centering
Between material purged, the purging of material maximum area realized with this, ensure the uniformity of dry materials, and drying efficiency
Maximize.
Specifically, can be according to drying time, in drying time when carrying out the Bit andits control of point airduct air-distribution device
When more than half or drying time reaches preset time, airduct air-distribution device will be divided to adjust to former two first point of adjacent wind branch pipe 2
Between the two away from midpoint, to centre material purge, the purging of material maximum area is realized with this, ensures dry materials
Uniformity, and the maximization of drying efficiency.
Same can also will be divided to airduct air-distribution device to be moved to original two adjacent first in the 1/3 dry period
Point wind branch pipe 2 between the two away from 1/3 at, when 2/3 period, airduct air-distribution device will be divided to be moved to adjacent first point of original two
Wind branch pipe 2 between the two away from 2/3 at, can so realize, during drying, each point of material is blown by hot blast
Effect, and can slightly be adjusted on the time so that the drying of material more uniformly rationally.
Lossless electric-type divides the control method of airduct drying system also to include：Detect drying system run time；It is when drying
When run time of uniting reaches preset time, control end divides wind branch pipe 4 to rotate predetermined angle around own torque.Due to each end point
There is certain interval between wind branch pipe 4, during drying, to guarantee that fully material is dried, wind is divided in end
Branch pipe 4 can suitably be rotated in the drying process, to avoid partial material from not being purged to.
According to embodiment of the present utility model, lossless electric-type divides the control method of airduct drying system to include：Detect air intake
Air quantity in house steward 1；When detecting that the air quantity in air intake house steward 1 is less than default air quantity, open Part I first and divide wind branch
Control valve on pipe 2, the control valve that other parts first are divided on wind branch pipe 2 is closed, and run the t1 times；Open Part II the
Control valve on one point of wind branch pipe 2, the control valve that the outer other parts first of Part II are divided on wind branch pipe 2 is closed, and run t2
Time, wherein Part I first divides wind branch pipe 2 to divide wind branch pipe 2 different from Part II first；Each several part first is controlled successively
The control valve divided on wind branch pipe 2；After the control valve on all first point of wind branch pipes 2 is opened once, all are opened
Control valve on one point of wind branch pipe 2, carry out low wind speed drying.
Due to being to utilize environmental natural wind, during purging, it may appear that the problem of air quantity is suddenly big or suddenly small, air quantity are too small
The purging of effective penetrability can not be realized, the moisture that effectively can not be taken out of in time in bed material, when long-time air quantity is too small, such as
Fruit is sent into the bed of material all through more wind-distributing pipe roads and dried, then can bring above-mentioned phenomenon, to avoid the generation of above-mentioned phenomenon,
Increase corresponding control device on each point of supervisor, increase corresponding detection module inside pipeline, when detecting that air quantity is long
Between it is too small when, the operating method of local air-valve is opened by closing or turning down most of air-valves, material is purged, can
Air quantity is effectively adjusted, ensured to the drying effect inside material.For example, in the present embodiment, be originally located in it is middle and
The valve of control valve 6 on first point of wind branch pipe 2 of bottom is closed, the valve of the control valve 6 on first point of wind branch pipe 2 on top
To open, after Wind Volume purging a period of time, the valve of the control valve 6 on first point of wind branch pipe 2 on top is closed, and middle first
The valve opening of control valve 6 on point wind branch pipe 2, the valve of the control valve 6 on first point of wind branch pipe 2 of bottom still keep closing
Closed state；After same purging, top, the valve of control valve 6 on first point of middle wind branch pipe 2 are closed, bottom
The valve opening of control valve 6 on first point of wind branch pipe 2, after Wind Volume purges a period of time, first point of wind of three parts
Valve wide open on branch pipe 2, carry out low wind speed drying.
Using such scheme of the present utility model, there is advantages below：
1st, only need to put into nonrecurring cost, and input cost is not high, and power, energy-conserving and environment-protective need not be consumed in running：
2nd, microbial activities is reduced, carbon source consumption is reduced, improves calorific value indirectly；
3rd, Free water in biomass is evaporated, reduces moisture in biomass, the moisture into burner hearth is reduced, so as to improve fuel
Calorific value, improve boiler combustion efficiency；
4th, in purge, by a part of ash content, native slag blow out, so as to avoid enter into boiler, reduce to boiler water wall,
The abrasion of the parts such as heat exchanger, economizer, air preheater；
5th, in burner hearth moisture reduction, reduce the low-temperature corrosion of back-end ductwork；
6th, the overall efficiency in power plant is improved；
7th, the consumption of fuel is reduced to a certain extent, reduces the expenditure of cash flow, reduces enterprise operation burden.
Certainly, above is preferred embodiment of the present utility model.It should be pointed out that the ordinary skill for the art
For personnel, on the premise of the utility model general principle is not departed from, some improvements and modifications can also be made, these improvement
The scope of protection of the utility model is also considered as with retouching.
