Abstract
The invention discloses a drying system for drying straws, which comprises a tubular type air heat collection device, a single-row movable drier, a fan and an electric-heating fan. The fan is connected with the air inlet of the tubular type air heat collection device. The air outlet of the tubular type air heat collection device is connected with the air inlet of the single-row movable drier. The electric-heating fan is also connected with the air inlet of the single-row movable drier. The drying system realizes the combination of the tubular type air heat collection device using solar energy and the electric-heating fan. When the tubular type air heat collection device works normally in sunny day, the system can meet the requirements for straw drying process and minimize the energy consumption. When the tubular type air heat collection device fails to work or in rainy day, the drying operation is completed by electric heating. The invention realizes the complementation of new energy sources and conventional energy sources, and meets the requirements for industrial drying of straws.
Description
Technical field
The invention belongs to drying, relate in particular to a kind of drying system of dry straw.
Background technology
Solar energy is the topmost new forms of energy that slow down and solve environmental problem, and people begin to utilize solar energy to carry out drying very early, the crops of gathering in is placed to tan by the sun under the sun dehydrate, so that long preservation is the drying mode that continue to use for a long time in the rural area.But not only floor space is big for this traditional drying mode, subjects to the pollution of dust, worm excrement and drenches with rain, and influence product quality, and drying time is also long, can not satisfy need of industrial production.
Summary of the invention
The drying system that the purpose of this invention is to provide a kind of dry straw.
For achieving the above object, the present invention adopts following technical scheme: a kind of drying system of dry straw, comprise tubular type air collector, single traveling drier, blower fan and electric calorifier, blower fan links to each other with the air inlet of tubular type air collector, the air outlet of tubular type air collector links to each other with the air inlet of single traveling drier, and electric calorifier also links to each other with the air inlet of single traveling drier.
Also comprise attemperating unit, attemperating unit links to each other with electric calorifier with blower fan respectively.
Described tubular type air collector comprises the cavity of being made up of heat-insulation layer and double-layer heat insulation glass, is attached with the reflecting layer on the heat-insulation layer, and air collector tube is fixed in the cavity by support, and air inlet and air outlet are arranged on the air collector tube.
This drying system will utilize the tubular type air collector and the supporting use of electric calorifier of solar energy, when sunny, when the tubular type air collector normally moves, can satisfy the requirement of stalk drying process, saved the energy greatly; And when overcast and rainy or tubular type air collector can not normally move, can start electrothermal drying, realize the complementation of new forms of energy and conventional energy resource, thereby guarantee the needs of straw industrialization drying.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 looks schematic diagram for the master of tubular type air collector.
Fig. 3 is the A-A schematic diagram of Fig. 2.
The specific embodiment
The drying system of dry straw as shown in Figure 1, comprise tubular type air collector 3, single traveling drier 4, blower fan 1 and electric calorifier 2, blower fan 1 links to each other with the air inlet of tubular type air collector, the air outlet of tubular type air collector links to each other with the air inlet of single traveling drier, and electric calorifier also links to each other with the air inlet of single traveling drier.Also comprise attemperating unit, attemperating unit links to each other with the electric calorifier electricity with blower fan respectively, and the temperature measurement fraction of attemperating unit is contained in the body of single traveling drier.
As Fig. 2, shown in Figure 3, the tubular type air collector comprises the cavity of being made up of heat-insulation layer 10 and double-layer heat insulation glass, be attached with reflecting layer 6 on the heat-insulation layer, between internal layer insulation glass 12 and the outer insulation glass 11 air layer 13 is arranged, air collector tube 7 is fixed in the cavity by support 8, and air inlet 5 and air outlet 9 are arranged on the air collector tube.
The present invention selects single multilayer traveling drier for use, and promptly stalk is placed on a row in a certain direction on the conveyer belt of motion, and conveyer belt is circuitous moving in drying shed, the motion of formation multilayer, increase the time of contact of stalk and hot-air, make full use of the heat of air, improve drying efficiency.
The course of work of the present invention is: solar energy has heated the air in the tubular type air collector, and hot-air enters in the single traveling drier, and the straw on the conveyer belt is carried out drying.Temperature control system is regulated the rotating speed of blower fan according to the temperature in the drying machine, thereby changes the temperature that enters the hot blast in the drying machine, reaches optimum drying effect.When luminous energy is not enough, can start electric calorifier as a supplement, satisfy the needs of straw industrialization drying.
Drying mechanism of the present invention is summarized as follows: water capacity is d1, and relative humidity is
Temperature becomes temperature T 2, water capacity d2, relative humidity after being the cold air process tubular type air collector of T1
Hot-air, T2＞T1, d2=d1, its wettability power is improved.Hot-air absorbs the moisture in the stalk during through single traveling drier, and temperature reduces to that T3, water capacity become d3, relative humidity becomes
D3＞d2,
Humid air after the moisture absorption is discharged drying equipment by moisture exhausting port, and the moisture content of stalk drops to below 6% by 15%, thereby reaches the purpose of dry stalk.
