Abstract
The utility model discloses a kind of tea drier heat exchanger, comprise boiler, dryer, connect the inlet manifold between boiler and dryer and return main, be arranged on the oven dry coil pipe be connected with inlet manifold in dryer; Also be provided with return duct in described dryer, one end of return duct is connected with the port of export of drying coil pipe, and the other end is connected with return main.The utility model effectively can improve the heat utilization rate of tea drier, reduces energy waste and saving water resource.Meanwhile, the security of boiler can be improved.Tea drier field can be widely used in.
Description
Technical field
The utility model relates to tea drier field, especially relates to a kind of tea drier heat exchanger.
Background technology
Drying tea leaves is a procedure of the indispensability of tea-manufacturing technology, and along with industrialization and the mechanization of Tea Production, drying tea leaves also changes big machinery drying plant into from initial manual charcoal drying mode.In recent years, successively occurred flat and tunnel drier, but this kind of machinery is heated, and easily causes Destruction of Chlorophyll, affects tea quality uneven.So more advanced exchange type dryer instead of original drying plant gradually, usually, in exchange type dryer, be provided with heat-exchange tube, discharge after vapours flows out drying machine in boiler or flow back to boiler.But because vapours temperature is high, after outflow dryer, still have higher temperature, there is a large amount of steam, if directly flow back to boiler, it is arranged on the water pump of boiler end because the pressure of steam is very easy to damage.If directly discharge, this just causes the dual waste at the energy and water source.
Utility model content
The purpose of this utility model is to provide a kind of tea drier heat exchanger, solves existing tea drier heat utilization rate low, the problem that energy consumption is large.
The utility model solves the technical scheme that its technical problem adopts: a kind of tea drier heat exchanger, comprise boiler, dryer, connects the inlet manifold between boiler and dryer and return main, is arranged on the oven dry coil pipe be connected with inlet manifold in dryer; Also be provided with return duct in described dryer, one end of return duct is connected with the port of export of drying coil pipe, and the other end is connected with return main.
For improving afflux amount, make steam have the condensation of longer Distance geometry time, be also provided with and the header of drying the coil pipe port of export and being connected, the backflow air inlet pipe be connected with header, the backflow escape pipe be connected with return duct, is provided with one group of arm that refluxes between backflow air inlet pipe and backflow escape pipe.
For effectively controlling flow, maintain easily process, described inlet manifold is provided with flow-limiting valve, the port of export of described header, the port of export of reflux arm and backflow escape pipe are provided with relief valve.
Preferably, described oven dry coil pipe is provided with 3 air inlets and 3 gas outlets.
The beneficial effects of the utility model: by increasing by one group of return duct, again import gas-vapor mix out from dryer in dryer and carry out heat exchange, improve heat utilization rate, reduce energy consumption.Water with temperature is turned back to boiler and again boils utilization, namely decrease the boiled required energy of this part water, again save water resource.Described backflow arm can to greatest extent by steam-condensation Cheng Shui.The water flowed out through return duct is got back in boiler through return main again, and because this part water temperature is lower, and vapours is less, reduces the boiling amount of boiler, improves the security of producing.
Below with reference to drawings and Examples, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment, as shown in Figure 1, a kind of tea drier heat exchanger, comprises boiler 1, dryer 2, connects the inlet manifold 3 between boiler 1 and dryer 2 and return main 4, is arranged on the oven dry coil pipe 5 be connected with inlet manifold 3 in dryer 2.Oven dry coil pipe 5 is provided with 3 air inlets and is connected with inlet manifold 3, and be also provided with 3 gas outlets at oven dry coil pipe 5 port of export, the water temperature of drying coil pipe 5 port of export, at 90 ~ 100 DEG C, exists a certain amount of steam.Described oven dry coil pipe 5 port of export is connected with header 7, and the end of header 7 is connected with backflow air inlet pipe 8, is also provided with backflow escape pipe 9, is provided with one group of arm 10 that refluxes between backflow air inlet pipe 8 and backflow escape pipe 9.Described backflow escape pipe 9 is connected with return duct 6.Described return duct 6 is placed in dryer, its port of export is connected with return main 4, the entrance point of described return duct 6 is positioned at the below of the port of export, and return duct 6 is positioned at the below of return main 4, utilizes the pressure of gas-vapor mix by the hydraulic pressure Huis supply mains 4 in return duct.This return duct structure can improve the energy utilization rate of dryer, reduces energy waste.
Described inlet manifold 3 is provided with flow-limiting valve 11, for controlling the heat entering air inlet coil pipe.The port of export of described header 7, the port of export of reflux arm 10 and backflow escape pipe 9 are provided with relief valve 12, facilitate the maintenance of each section of pipeline, and are conducive to water vapor condensation Cheng Shui.
