Description
Technical field
The invention belongs to the renewable energy utilization technology, relates generally to a kind of device of bearing and accomplish the crops drying operation with solar energy combination greenhouse.
Background technology
The cereal drying is important process process in the processing of farm products process, and purpose is to remove redundant moisture in the cereal, so that product processing, transportation, storage and use.Adopt conventional drying cereal and other agricultural product, investment is big, needs to consume a large amount of coals, fuel oil equal energy source, causes costs of farm produce to increase, and causes environmental pollution in various degree.The baking temperature of cereal and general agricultural product requirement is lower, greatly between 40-55 ℃, is complementary with low-temperature heat utilization in the solar energy heat utilization field; With the artificial solar energy drying cereal of gathering; Can shorten arid cycle, improve the quality of products, still; Should technology not obtain development and use as yet at present, still belonged to blank.
Summary of the invention
The purpose of the invention is exactly the problem that exists to above-mentioned prior art; Design provides a kind of greenhouse heat accumulation type solar energy hot blast grain drying device; Accomplish the bake drying operation of agricultural crops through the mode of all utilizing solar thermal energy, reach and practice thrift non-renewable energy resources, reduce operating cost, reduce the purpose of environmental pollution.
The purpose of the invention is achieved in that subsurface is provided with underground heat accumulation tank in drying shed room, greenhouse, and the air channel division wall is set in underground heat accumulation tank, and heat accumulating is filled in the underground heat accumulation tank; The drying shed outer upper is installed solar energy air heat collector in the greenhouse; Hot blast conveying pipe and cold air loopback pipe are configured in the greenhouse drying shed; The two ends of hot blast conveying pipe are communicated with the air outlet of solar energy air heat collector and the air inlet of underground heat accumulation tank respectively; Induced-draught fan and the 3rd valve are fitted on the hot blast conveying pipe, and the cold air loopback pipe two ends of equipped first valve are communicated with the air inlet of solar energy air heat collector and the air outlet of underground heat accumulation tank respectively; The hot blast discharge pipe that on tube wall, is provided with vent is configured in the greenhouse drying shed; The two ends of hot blast discharge pipe are communicated with hot blast conveying pipe and cold air loopback pipe respectively; The tie point of hot blast discharge pipe and hot blast conveying pipe is between induced-draught fan and the 3rd valve; The tie point of hot blast discharge pipe and cold air loopback pipe is between first valve and solar energy air heat collector air inlet, and second valve is fitted on the hot blast discharge pipe; Hair-dryer and automatic controller configuration are installed in the greenhouse drying shed, and lead is connected automatic controller respectively with induced-draught fan, hair-dryer, first valve, second valve, the 3rd valve; On greenhouse drying shed wall, be provided with exhaust outlet, so far constitute greenhouse heat accumulation type solar energy hot blast grain drying device.
The invention utilizes solar energy drying cereal from three aspects: first utilizes the building structure in greenhouse, directly accepts sunlight, improves the temperature of hothouse, is equivalent to the dried grain of natural drying formula; Second utilizes the high-temperature hot-air of solar energy air heat collector, blows in the greenhouse drying shed, further improves the temperature of drying shed, quickens the cereal dry run; The 3rd utilizes underground heat accumulation tank heat energy, makes hothouse terrestrial surface radiation heat energy, is equivalent to dry by the fire the dried grain of a heatable brick bed formula, further quickens the cereal drying.More than three kinds of ways concentrate and use, the high wind of auxilliary again hair-dryer, the air that quickens drying shed flows, just can take the damp steam in the cereal out of rapidly, through the exhaust outlet of wall behind the greenhouse, row in atmosphere, the drying of realization cereal.
The characteristics of the invention are: (1) is simple in structure, and is cheap, easy and simple to handle, and drying cost is low, can suit measures to local conditions to build, and is fit to vast rural area and adopts on the spot; (2) fuel saving, according to the estimation of relevant technologies data, normal pressure is evaporation 1kg water down, needs 2.5*10 approximately
3The heat of kl/kg.For this reason, dry 1 ton of agricultural byproducts approximately will consume the raw coal more than 1 ton; (3) minimizing is to the pollution of environment.Atmosphere pollution comes from the flue dust and the waste gas of fossil energy burning back dischargings such as coal, oil, adopts solar energy drying cereal, not only practices thrift fossil fuel, also can alleviate environmental pressure; (4) operating cost is low.With regard to initial cost, solar energy and conventional energy resource drying are more or less the same.But during system's operation, solar energy drying is much lower than the dry expense of conventional energy resource, generally has only about 30% of conventional energy resource operating cost.
