Description
Technical field
The present invention relates to heat recovery technology field, especially a kind of waste-heat recovery device of wood drying kiln.
Background technology
The drying of wood is process procedure mostly important in woodwork production process, and its energy consumption accounts for woodwork production total energy
The 40%~70% of consumption, during Wood drying, the heat energy contained by the Hot wet air heating of hothouse discharge accounts for entirely
More than the 56% of whole energy consumptions in drying process, if which part energy can be recycled, production energy-conservation is dried to not guessing
It is significant.Conservation measures to wood drying kiln carries out largely analysis and discussion and drawn：No matter single heat source formula or double
Heat source type heat pump drier, its energy consumption are all significantly lower than steam drying, and selfexcited oscillating-flow heat pipe changes under given operating condition
The heat recovery rate of hot device residual neat recovering system is higher than 18%, and heat exchange of heat pipe is in timber conventional drying room exhausting heat energy recovery technology
Research is when drawing heat exchange of heat pipe energy recovery efficiency highest, and economic benefit preferably when heat exchange of heat pipe optimum proportioning, be
Energy consumption is reduced, a kind of pressure is investigated and concentrates air interchanger, admission line is separated, made by the device with discharge duct by aluminium sheet
Hot wet air heating delivers heat to the Cryogenic air in admission line in discharge process by aluminium sheet, plays certain recovery effect, but
The outdoor Hot wet air heating of discharge still carries amount of heat.
The content of the invention
The technical problem to be solved in the present invention is：Based on above mentioned problem, there is provided a kind of waste heat recovery dress of wood drying kiln
Put.
The technical solution adopted for the present invention to solve the technical problems is：A kind of waste-heat recovery device of wood drying kiln,
Include the housing of cylindrical shape, one end of the housing is provided with fresh dry air admission line, the fresh dry air air inlet pipe
Suction blower fan is provided with road, the other end of housing is provided with admission line, and the top of housing has discharge duct, the exhaust
Pipeline is connected a reversal valve with admission line, and some heat exchanger tubes are horizontally arranged with housing, is vertically arranged with some deflection plates,
Hot wet air heating discharge duct is provided with the periphery of housing, the Hot wet air heating discharge duct is provided with discharge blower fan.
Further, the deflection plate is arched, and the cut height of deflection plate is the 40% of housing inner diameter.
Further, the heat exchanger tube is single tube journey, and the tube pitch of two heat exchanger tubes is 40mm.
The beneficial effects of the invention are as follows：Into hothouse fresh dry air by the present invention waste-heat recovery device after,
Temperature can improve 9~12 DEG C, and Hot wet air heating temperature declines 13~17 DEG C, and heat recovery rate is 19%~28%, and average efficiency is
22%.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
In figure：1. housing, 2. fresh dry air admission lines, 3. suction blower fans, 4. admission lines, 5. discharge ducts, 6.
Reversal valve, 7. Hot wet air heating discharge ducts, 8. discharge blower fans, 11. heat exchanger tubes, 12. deflection plates.
Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
As shown in figure 1, a kind of waste-heat recovery device of wood drying kiln, including cylindric housing 1, one end of housing 1
Fresh dry air admission line 2 is provided with, suction blower fan 3, the other end of housing 1 are provided with fresh dry air admission line 2
Admission line 4 is provided with, the top of housing 1 has discharge duct 5, and discharge duct 5 is connected a reversal valve 6 with admission line 4,
Some heat exchanger tubes 11 are horizontally arranged with housing 1, are vertically arranged with some deflection plates 12, it is wet that heat is provided with the periphery of housing 1
Air exhaust pipeline 7, Hot wet air heating discharge duct 7 are provided with discharge blower fan 8.
Wherein, deflection plate 12 is arched, and the cut height of deflection plate 12 is the 40% of the internal diameter of housing 1.Heat exchanger tube 11 is single
Tube side, the tube pitch of two heat exchanger tubes 11 is 40mm.
In the waste-heat recovery device of this implementation, low temperature fresh air is in tube side, and high temperature Hot wet air heating is in shell side, and low temperature is fresh
Dry air is sent into fresh dry air air inlet heat exchanger tube 11 by sucking blower fan 3, and high temperature Hot wet air heating discharges shell by discharge blower fan 8
Body 1, in the drying process, by the opening and closing of reversal valve 6, corresponding corresponding air inlet and exhaust piper causes the hot wet sky of housing 1
After gas is derived from material heap medium stream export direction all the time, while the fresh dry air supplemented is by housing 1, all the time with from material
Material heap is flowed into again by heater after the cyclic drying medium stream mixing of heap outflow.
It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
