Air preheater is a kind of for the dual cavity single-pass configuration casing of the invention specially designed, and solar energy heating
Device pipe group fits together, and air is introduced into cold chamber, enters solar thermal collector bottom then along 304 steel pipes, in 304 steel
Gradually heat up in pipe, subsequently reverse flow, temperature of continuing rising relayed in solar thermal collector, finally from the solar thermal collector mouth of pipe into
Enter hot chamber, flow channel is unique.In the process, cold air will not be directly entered solar thermal collector, can reduce
The temperature difference of solar thermal collector tube wall and cold air, reduces tube wall stress, protects solar thermal collector, increases service life.It is empty
The volume ratio of the two chambers of air preheater will design on the premise of atmospheric density ratio, heat-transfer character is considered, it is accorded with substantially
Temperature requirement is closed, i.e., hot chamber indoor temperature is close to drying requirement.
Hot air duct and air-introduced machine 1 are connected with air preheater outlet, and hot-air is introduced baking room by air-introduced machine 1, to thing
Product are dried；Cold air duct and air-introduced machine 2 are connected with the cold chamber of air preheater, cold air enter solar thermal collector it
The preceding preheating for receiving hot-air.Air preheater, hot air duct and air-introduced machine 1, baking room, cold air duct and air-introduced machine 2 are formed
The air backheating system of the present invention.Hot air duct and air-introduced machine 1 are arranged in below right-side wall, 2 cloth of cold air duct and air-introduced machine
Put above the wall of left side, this structure meets the natural law, is conducive to air flow.
Humidity sensor is installed in baking room, when humidity reaches predetermined moisture angle value, starts dehydrating unit and dehumidifies
Processing；Temperature sensor is installed at baking room hot-wind inlet, when temperature exceedes predetermined temperature value, starts temp.-control valve, into
Row cooling is handled.
