Conventional drier has electrical drying device, coal-fired drier, fuel oil drier and heat pump drier at present.Wherein, heat pump drier is energy-efficient because having, safety and environmental protection, the achieve effective control of humiture energy and can keep preferably the advantage such as quality of material to receive much concern, and is subject to practical more and more widely in recent years.But also there are some problems in current heat pump drier, the problem such as wherein distinct issues are exactly that drying time is long, equipment investment is large, dust and waste gas leak.In order to improve the shipment amount and the requirement that meets environmental protection of drying system, often more complicated of the Analysis of Heat Pump Drying System adopting, and system is larger, thus cause equipment investment significantly to increase, and this has just seriously restricted promoting the use of of heat pump drier.
By literature survey, the research of heat pump drier is mainly concentrated on to the following aspects both at home and abroad at present: for its optimum operating condition of different material experimental studies; Improve heat pump part to improve baking temperature; In heat pump drier, utilize regenerative resource and new forms of energy as solar energy etc., but these all fail fundamentally to address the above problem.
Summary of the invention
The purpose of this utility model is for the above-mentioned defect existing in prior art, a kind of new type solar energy drying system taking solar energy as main thermal source is provided, the problems such as it has solved that existing drier energy-output ratio is large, the wasting of resources, heat pump drier exist drying time is long, equipment investment is large, dust and waste gas leak, can reach not only energy-conservation but also environmental protection.
The purpose of this utility model realizes by the following technical solutions: this new type solar energy drying system, it comprises and is installed on outdoor solar thermal collector, solar thermal collector is connected to form a hydrothermal circulation system with the heat exchanger being installed in hot water storage tank by pipeline, air bleeding valve and water circulating pump are installed in connecting pipe, on the water inlet pipe of hot water storage tank and drainage pipeline, are separately installed with ball valve; Hot water storage tank be installed on the underfloor ground warm device of hothouse and be connected to form a hydrothermal circulation system by pipeline, water circulating pump and electric three passes are installed in connecting pipe; Hothouse is connected to form a wind-heat circulatory system with water-cooled evaporimeter and water cooled condenser successively by airduct, on the air outlet of airduct, hot air circulation blower is installed; Between water-cooled evaporimeter and water cooled condenser, be connected with compressor, four-way change-over valve, choke valve and electric three passes.
Specifically, described solar thermal collector and hot water storage tank are installed on the roof of hothouse.Described ground warm device mainly comprises and is layed in the underfloor water pipe of hothouse.
The utility model utilizes the photo-thermal transforming principle of solar energy, rely on solar thermal collector to collect solar energy, the heat energy that utilization is collected also stores wherein as the water in thermal source heating hot water storage tank, by rise thermal insulation delivery pipe road, the water of high temperature is delivered in the pipeline of laying in hothouse floor, by the flooring radiation rising indoor air temperature that dispels the heat.First from water cooled condenser, emit the dry gas of high temperature low humidity, with the acting in conjunction of solar heat thermal source, the material in hothouse is carried out to heat drying.Material can rapid draing in the gas of high temperature low humidity, inferior hot and humid gas is discharged and is entered water-cooled evaporimeter through airduct from hothouse, the cooling moisture of separating out, form low temperature and low humidity gas, after processing through water cooled condenser, again obtain the gas of high temperature low humidity, the gas of this high temperature low humidity reenters in hothouse and does further and be dried, and forms a complete dry cycle process.
The solar thermal collector that the utility model applies to and the ground warm device that the solar energy of collection is fully utilized are all the settings of strengthening solar energy utilization ratio.Solar thermal collector can adjust flexibly towards and inclination angle, to improve the utilization rate of solar energy, and ground warm device is that unnecessary solar energy is carried out to thermal power transfer, the pipeline of laying under the floor, flow of hot water drying chamber of heat accumulation is to be reached for the effect of the gas-heated that is dried indoor moveable.The utility model utilizes the mode of the dry indoor gas of dual-heated to provide continuously and the origin of heat of high-quality for dry, has strengthened drying efficiency, has accelerated drying time, has reduced energy input.Aspect environmental protection, gas circulation utilization, so just can shield leaking of dust and waste gas in addition, and dust and waste gas are realized to control effectively, avoids its contaminated environment.
