Description
Technical field
The utility model relates to a kind of system of recycling solar energy drying waste gas residual heat, especially adopts the middle high temperature solar drying system of slot light collection thermal-arrest, belongs to solar energy utilization technique field.
Background technology
In the main trend of current this energy resource consumption, the conventional energy resources such as coal, oil, natural gas can to environment cause huge pollution and some day can exhaustion totally, solar energy is wherein played the part of more and more important role as a kind of emerging energy at this.Solar energy drying with its feature such as easy, energy-conservation, pollution-free, has replaced rapidly other traditional drying technology as solar thermal utilization one important branch, becomes at present one of primary study project both at home and abroad.Solar energy drying is human use's solar energy a kind of form generally with the longest history, most widely used, and solar energy drying is to replace conventional energy resource to carry out the process of heat medium with solar energy.
The solar energy drying system relating to is at present mostly open system, imports and exports onrelevant, and the using waste heat from tail gas after drying medium is not used and directly discharge; Some drying system is designed to enclosed drying system, although now the waste heat of tail gas is recycled, but reenter and in the tail gas of system, contain a large amount of steam and EGR is done perfectly not to the dehumidifying of this portion gas, therefore the efficiency of whole dry run can not make moderate progress.
Summary of the invention
The purpose of this utility model is to have proposed a kind of solar energy drying system, and this drying system can be recycled the part of waste heat of getting rid of from drying box, thereby can improve the thermal efficiency of solar energy drying system.
The utility model completes by the following technical programs: a kind of back-heating type solar energy drying system, comprises trough type solar heat-collector, heat transfer pipe, heat medium pump, heat storage can, heat exchanger, air blast and ventilation shaft; The outlet of air blast is connected with the entrance of the zone of heat liberation of heat exchanger, and the outlet of the zone of heat liberation of heat exchanger is connected with the entrance of drying box; The endothermic tube of trough type solar heat-collector, heat storage can, heat medium pump and heat exchanger zone of heat liberation coil pipe are connected in series by heat transfer pipe, it is characterized in that: be provided with a regenerator with heat exchange effect, the entrance of the zone of heat liberation of this regenerator connects the waste gas outlet of drying box, and the outlet of the cold fluid pass of regenerator connects the entrance of air blast.Like this, the Cryogenic air of the regenerator cold fluid pass of flowing through heats the higher dry waste gas of temperature of the regenerator zone of heat liberation of being flowed through, will be lower and be discharged into airborne dry waste gas temperature, thus improved the thermal efficiency of cycle of drying system.
The beneficial effects of the utility model are: utilize cold air to carry out heat exchange with tail gas in bootstrap system, before the heat exchanger that arrives drying system, reach a higher temperature, reduce to a certain extent the load of groove type solar light-condensing and heat-collecting device, improve the efficiency of whole drying system.
