The objective of the invention is to invent a kind of raisins drying equipment, use the method for oven dry thermal source and power source one, whole device does not need other electric energy input and certain electric energy output is arranged.Very high production efficiency is arranged, be suitable for large-scale production.
Structure of the present invention is shown in attached Fig. 1 and 2.It has drying conveyor 11, transmit tape holder 12, belt-driven motor 13, drying channel 14, cloth mouth 15, discharging feeder 16, it is characterized in that: have by low-pressure compressor 1, high-pressure compressor 2, combustion chamber 3, high-pressure turbine 4, the dual-rotor aviation turbofan engine 6 that low-pressure turbine 5 is formed, be connected to free power turbine 7 at turbofan 6 rear portions, free power turbine 7 drives generator 8, free power turbine 7 exhaust outlets are connected to air heat exchanger 9, after the outer culvert air communication of being discharged by low-pressure compressor is crossed air heat exchanger 9 heating, are connected to air ejector 10.
Accompanying drawing 1 is a general structure schematic diagram of the present invention.
Accompanying drawing 2 is the main heat blower structural representation of forming with the aerial turbo fan engine for the present invention.
Operation principle of the present invention is as follows.New fresh grape is dispersed evenly on the conveyer belt 11 by cloth mouth 15, and conveyer belt 11 drives grape and moves to discharge end.Send into the drying channel 14 from cloth mouth end by the hot-air that air ejector 10 is discharged, with the grape effect.Because hot air flowrate is bigger, and certain temperature (a certain the require temperature of Controllable Temperature in 80～200 ℃ of scopes) is arranged, thereby rate of drying is very fast.When conveyer belt 11 is delivered to discharge port end to grape, finished the oven dry task, by 16 outputs of discharging feeder.The hot gas exhaust is discharged by the opening of discharging feeder top.
Among the present invention, the dual-rotor aviation turbofan engine of being made up of low-pressure compressor 1, high-pressure compressor 2, combustion chamber 3, high-pressure turbine 4, low-pressure turbine 56 provides the power of whole device.In the present invention, outside air is sucked by low-pressure compressor 1 and compresses, and low-pressure air after compression is divided into two parts (the intension air-flow of corresponding engine and the outer air-flow of containing).The outer air-flow of containing is drawn as the oven dry heated air source.And the intension air-flow, is sent into combustion chamber 3 and is added fuel combustions after high-pressure compressor 2 further compresses as the air source of turbogenerator 6, and the power of whole device is provided.High-temperature high-pressure fuel gas after the burning expands by high-pressure turbine 4 and low-pressure turbine 5 and does work.Drive low compressor 1 and high-pressure compressor 2 rotation works again after high-pressure turbine 4 and low-pressure turbine 5 absorbs energy, constitute an autonomous independent operating of energy, do not need the external world that the heat blower and the power source integrated apparatus of other form energy are provided.Because the combustion gas of discharging through former nozzle of aircraft engine tail also contains a large amount of kinetic energy and interior energy, therefore install a free power turbine 7 additional, energy in a kinetic energy in the absorption exhaust and the part.Free power turbine 7 drives generator 8 generatings, and drying conveyor rotational energy of the present invention and its power needs of base are provided.After free power turbine, fuel gas exhaust also has energy in certain low-heat, carries out heat exchange by air heat exchanger 9 and low-pressure compressor 1 outer culvert exhaust, contains the temperature of air-flow outside improving, and further recovers energy.Because outer culvert stream pressure is bigger, temperature is also higher after heat exchange, therefore for reducing the temperature of temperature and adjusting control delivery air, be connected to air ejector 10, the outer air of containing is mixed with outside air, mix the temperature of recently regulating the heat outputting air by control and regulation, to satisfy the needs of different oven dry.
In the present invention, heat blower and power source integrated apparatus are by dual-rotor aviation turbofan engine Transform Type design or directly repacking.In Transform Type design or directly in the repacking, need only block the connected entrance between the by-pass air duct of former engine and the nozzle and contain the air-flow outlet on the casing, draw the outer air-flow of containing and get final product.Because the air property during these turbofan 6 operations does not change, working condition is constant, so the aerodynamic parameter of whole engine and not change of thermal parameter, so only repacking workload that need be very little, thereby its controlling organization and control parameter all need not change.Engine also is operated in original optimum Working, makes full use of the optimum working efficiency of aero-engine.The free power turbine 7 that is connected at aerial turbo fan engine nozzle place is present gas turbine earth station standard device, has become series of products, can directly choose the model that is complementary with used aero-engine.
The present invention adopts the design that utilizes existing aero-engine or directly utilizes existing aero-engine to reequip, and self has prime mover, has realized the integrated of oven dry thermal source and power source.Owing to bigger electric energy output is arranged self,, can also export certain electric energy except that being used to drive the conveyer mechanism.Because aero-engine has very big thermal power, and adopt long drying channel form continuous drying, very high production efficiency is arranged, be suitable for large-scale production.
In the present invention, set up the equipment of 50 tons of daily output raisins, can use the SPEY512 aero-engine of Britain Luo Luo company (ROLLS-ROYCE) to reequip, or Transform Type design.When remodeling or repacking, fan is contained air-flow outward draws, send in the air heat exchanger of tail exhaust, can have flow to reach 38 Kilograms Per Seconds, pressure is that 0.24 MPa, temperature are the hot-air output about 460 ℃, the electric power of exportable 8 megawatts of generator that drive by free power turbine.
Can be as shown in Figure 3 form with the supporting air ejector 10 of above-mentioned power source, adopt telescopic injector, high-temperature hot air is introduced surrounding air from the central tube ejection.Central tube endoporus area can be 1: 5 with the ratio of outer sleeve area.At sleeve-port the valve that can control open amount can be housed, with control break injection mixing ratio.Air ejector 10 also can adopt orifice-plate type, as shown in Figure 4.It is made up of high-temperature hot air spray gun and orifice plate, and spray gun is apart from orifice plate opening certain distance, and perforated area is 1: 8 with the ratio of gun slot area.Orifice plate can directly be an opening on the drying channel wall.Air ejector 10 can also can adopt a big injector with undersized a plurality of parallel connections.
