Description
The utility model relates to a kind of drying equipment, especially a kind of Wood drying apparatus.
Existing a kind of timber dryer is made of hothouse and the steam heater that is positioned in the hothouse, and the steam that utilizes boiler to produce makes the steam heater heating, and the timber in the hothouse is carried out drying.Because this drying equipment needs by boiler heat supplying, its investment is bigger, and it is more to expend fuel, in being unfavorable for, small enterprise's employing.
The purpose of this utility model provides a kind of small investment, makes Wood drying apparatus easy, that fuel consumption is low, arid cycle is short.
Wood drying apparatus of the present utility model is provided with hothouse, combustion chamber and heat supply chamber in housing.The combustion chamber has smokejack, indoor radiator, blower fan and the sparge pipe of being provided with of heat supply.The inlet end of radiator advances mouth with combustion chamber outlet flue and smokejack respectively with the outlet side and links to each other, and the smokejack outlet flue communicates with hull outside.Be connected by air intake passage that separates setting and air-out passage between heat supply chamber and the hothouse, blower fan at the outlet and inlet passage between the indoor opening of heat supply.Radiator is positioned at the blower fan front end.The sparge pipe delivery port is towards radiator, and the sparge pipe water inlet is positioned at hull outside.Hothouse has at least two passages that communicate with hull outside, and each passage separates setting, and passage is provided with by-pass valve control.In the utility model, above-mentioned combustion chamber can be firebrand or fired coal combustion chamber, also can be fuel oil or gas combustion chamber.When using this dry device, the high hot flue gas that fuel produces when combustion chambers burn flow to smokejack through radiator, is discharged by the smokejack outlet flue, in this process again, most heats in the flue gas are distributed to heat supply is indoor by radiator, improve the indoor temperature of heat supply.In addition, spray water smoke by the sparge pipe delivery port to radiator, this water smoke contacts with red-hot radiator outer wall and at the indoor generation steam of heat supply.Because radiator is positioned at the blower fan front end, the heat that radiator sends and the steam of generation can enter hothouse through air intake passage under the promotion of blower fan wind-force, the timber in the hothouse are implemented dry.Meanwhile, air in the hothouse enters the heat supply chamber through the air-out passage, for blower fan provides wind regime, and then hothouse and the indoor air generation of heat supply are circulated, the high hot-air that promptly contains water vapour enters hothouse by air intake passage, air after the cooling then drains into the heat supply chamber by the air-out passage, enters hothouse once more after the indoor heating of heat supply.In the utility model, the purpose that allows the air that enters hothouse close suitable quantity of water steam is that the pressure that the air wet volume capacity strengthens, the timber internal water is discharged is reduced, and this both can accelerate rate of drying, helped preventing the timber crack again.By adjusting injection flow rate, can control the quantum of output of water vapour.In addition, when the dry processing of beginning, the passage of hothouse is closed condition.When the temperature and humidity in the hothouse reaches certain value, can open the by-pass valve control of passage.Because passage is at least two, and separates setting, under the effect of blower fan wind-force, the pressure reduction difference at different passages place, the passage of air pressure general goal is discharged the high hot highly humid air in the hothouse, and the passage at the little place of air pressure then sucks outdoor fresh air, promptly allows hothouse nature " ventilation ".After this process continued appropriate time, dry indoor air humidity reduced, and close the passage valve this moment again, timber was imposed next round is dry to be handled, until with the timber bone dry.Certainly, in order to promote the hothouse ventilation, also can scavenger fan be set at above-mentioned passage place.
Wood drying apparatus of the present utility model is compared with aforementioned existing same device, and it is made easily, and cost is corresponding lower.After room temperature reaches fiducial temperature in hothouse, only can continue to keep dry processing procedure, thereby can cut down the consumption of energy greatly with small amount of fuel.In addition, this device is convenient to control the air humidity in the hothouse, helps accelerating dry run, guarantees product quality.Undertaken preferably also can utilizing fume afterheat by the position that is provided with, further reduce fuel consumption flue.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
Fig. 1 is the structural representation of Wood drying apparatus among the embodiment.
Fig. 2 is A-A cutaway view.
Shown in Fig. 1～2, the Wood drying apparatus among the embodiment is provided with hothouse 2, fired coal combustion chamber 3 and heat supply chamber 4 in housing 1.Combustion chamber 3 has coal feed point 5, grate 6 and left and right smokejack 7,8.Be provided with multi-tubular radiator 9 blower fan 10 and sparge pipes in the heat supply chamber 4.The delivery port 11 of sparge pipe is towards radiator 9, and the water inlet 12 of sparge pipe is positioned at the outside of housing 1.The inlet end of radiator 9 advances mouth 14 with combustion chamber outlet flue 13 and smokejack respectively with the outlet side and links to each other.Smokejack outlet flue 15 communicates with hull outside.Be connected by air intake passage 16 that separates setting and air-out passage 17 between heat supply chamber 3 and the hothouse.Blower fan 10 at this outlet and inlet passage 16,17 between the indoor opening of heat supply.Radiator 9 is positioned at the front end of blower fan 10.Hothouse 2 has two passages, 19,20, two passages that communicate with hull outside and separates setting, is provided with butterfly valve 21 on the passage.In the present embodiment, the purpose that left and right two groups of smokejacks 7,8 are set is to be convenient to utilize fume afterheat, and left and right smokejack is separately positioned on the both sides of hothouse 2.The radiating tube horizontally set of multi-tubular radiator 9 is so that heat radiation and water smoke is evaporated to steam.In addition, smokejack advances the flue gas distribution cavity that mouth 14 has formed left and right smokejack, and helps flue dust in this place's deposition, reduces environmental pollution.When using this device, can open hothouse door 18 earlier, in hothouse, insert timber after, again the hothouse door is closed.When timber was implemented dry the processing, on the one hand, the high hot flue gas in the combustion chamber 3 was discharged housing through smokejack 7,8 after radiator 9 heat radiations.On the other hand, the heat that radiator 9 distributes raises the temperature in the heat supply chamber 4, and makes the water smoke of sparge pipe delivery port 11 ejections become steam.Under the wind-force of blower fan 10 promoted, the air circulation in heat supply chamber 4 and the hothouse 2 flowed, and realizes the drying to timber.Handle the initial stage in drying, butterfly valve 21 is in closed condition.After dry processing a period of time, opened butterfly valve 21 can utilize the ventilation of the pressure reduction realization hothouse between the passage 19,20.
The multi-tubular radiator 9 that is adopted among the embodiment also can be replaced by the radiator of heat radiation type.In addition, butterfly valve 21 also can be replaced by the by-pass valve control of other forms such as magnetic valve, stop valve.
