The control method of lossless electric-type aeration drying system further includes：When detecting 2 region of each first point of wind branch pipe Air quantity when being greater than or equal to default air quantity, detect the temperature of 2 region of each first point of wind branch pipe；When detecting one or more When the temperature of 2 region of a first point of wind branch pipe is more than preset temperature, increase on first point of wind branch pipe 2 of the one or more 6 aperture of control valve；Or, reducing 6 aperture of control valve of other first point of wind branch pipe 2 or closing the control of other first point of wind branch pipe 2 Valve 6 processed；First point of wind branch pipe of one or more is increased while or, reducing 6 aperture of control valve of other first point of wind branch pipe 2 6 aperture of control valve on 2.

When detecting that air quantity everywhere is all higher than or is equal to default air quantity, then need to control the temperature inside material System, prevents internal batch temperature from drastically overheating and causing to be lost to material.By detecting the temperature of material various places inside, Ke Yifang Just material air quantity is adjusted so that the higher local air quantity of internal batch temperature is larger, to which temperature herein is fast Speed is taken out of by air, forms preferably heat dissipation and drying.

The control method of lossless electric-type aeration drying system further includes：Detect drying system run time；Work as drying system When run time reaches preset time, it is default that control divides air hose air-distribution device to be moved along the arragement direction of first point of wind branch pipe 2 Distance.In drying system operational process, since the laying spacing of first point of wind branch pipe 2 is larger, has part and be located at phase Region between two adjacent first point of wind branch pipes 2 cannot access sufficient drying, therefore, can be run in drying system Cheng Zhong, control divide air hose air-distribution device to be adjusted along the laying direction position of multiple first point of wind branch pipe 2 so that air hose cloth wind is divided to fill Region between the two first point of wind branch pipes 2 adjacent before capable of being adjusted to of the position for the first point of wind branch pipe 2 set, to centre Material purged or aspirated, purging or the suction of material maximum area are realized with this, ensures the uniformity of dry materials, and The maximization of drying efficiency.

Specifically, when carrying out the Bit andits control of point air hose air-distribution device, it can be according to drying time, in drying time When more than half or drying time reaches preset time, air hose 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, intermediate material is purged or is aspirated, purging or the suction of material maximum area are realized with this, is protected Hinder the uniformity of dry materials and the maximization of drying efficiency.

Similarly air hose air-distribution device can also will be divided 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, air hose 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, may be implemented in this way, during drying, make each point of material that can be blown by hot wind Effect, and can slightly be adjusted on the time, to make material drying more uniformly rationally.

The control method of lossless electric-type aeration drying system further includes：Detect drying system run time；Work as drying system When run time reaches preset time, control end divides wind branch pipe 4 to rotate predetermined angle around own torque.Since wind is divided in each end There is certain interval between branch pipe 4, during drying, to guarantee that fully material is dried, wind branch is divided in end Pipe 4 can suitably be rotated in the drying process, can not be purged to or be drawn into avoid partial material.

The control method of embodiment according to the present utility model, lossless electric-type aeration drying system includes：Detection air inlet is total Air quantity in pipe 1；When detecting that the air quantity in air inlet manifold 1 is less than default air quantity, opens first part first and divide wind branch pipe 2 On control valve, close other parts first and divide the control valve on wind branch pipe 2, and run the t1 times；Open second part first Divide the control valve on wind branch pipe 2, when closing the control valve that other parts first outside second part are divided on wind branch pipe 2, and running t2 Between, wherein first part first divides wind branch pipe 2 to divide wind branch pipe 2 different from second part first；Control each section first is divided successively Control valve on wind branch pipe 2；After the control valve on all first point of wind branch pipes 2 is opened once, all first are opened Divide the control valve on wind branch pipe 2, carries out low wind speed drying.

Due to being to utilize environmental natural wind, during purging or suction, it may appear that the suddenly big or suddenly small problem of air quantity, wind The too small purging that cannot achieve effective penetrability or suction are measured, the moisture in bed material can not be effectively taken out of in time, when long Between air quantity it is too small, if being sent into bed of materials drying all through more wind-distributing pipe roads, above-mentioned phenomenon can be brought, it is above-mentioned to avoid The generation of phenomenon increases corresponding control device on supervisor at each point, increases corresponding detection module inside pipeline, work as inspection Measure air quantity it is too small for a long time when, the operating method of local air-valves is opened by closing or turning down most of air-valves, to material It is purged or is aspirated, air quantity can effectively be adjusted, ensured to the drying effect inside material.For example, in this implementation In example, the valve for the control valve 6 being originally located on intermediate and lower part first point of wind branch pipe 2 is closed, first point of wind branch on top The valve of control valve 6 on pipe 2 is opened, and Wind Volume purged or after suction a period of time, the control on first point of wind branch pipe 2 on top The valve of valve 6 processed is closed, the valve opening of the control valve 6 on intermediate first point of wind branch pipe 2, first point of wind branch pipe 2 of lower part On the valve of control valve 6 still remain off；After same purging or suction, top, first point of intermediate wind The valve of control valve 6 on branch pipe 2 is closed, and the valve opening of the control valve 6 on first point of wind branch pipe 2 of lower part works as Wind Volume It purges or after suction a period of time, the valve wide open on first point of wind branch pipe 2 of three parts carries out low wind speed drying.

Using the said program of the utility model, has the following advantages：

1, input nonrecurring cost is only needed, and input cost is not high, without consuming power, energy conservation and environmental protection in operational process：

2, microbial activities is reduced, carbon source consumption is reduced, improves calorific value indirectly；

3, Free water in biomass is evaporated, moisture in biomass is reduced, the moisture into burner hearth is reduced, to improve fuel Calorific value improves boiler combustion efficiency；

4, in purging or aspiration procedure, a part of ash content, the blowout of native slag are reduced to avoid enter into boiler to boiler The abrasion of the components such as water-cooling wall, heat exchanger, economizer, air preheater；
