For achieving the above object, technical solution of the present invention is as follows:
A kind of drying of wood system comprises dry kiln, humidity generator, thermal energy recoverer, filter, control system, has inlet, outlet on the dry kiln; The high-temp waste gas that discharge the dry kiln gas outlet filters back input thermal energy recoverer through filter, the cryogenic gas that transports with humidity generator in thermal energy recoverer carries out discharging after the heat exchange, and the cryogenic gas after being heated of thermal energy recoverer output is sent into the dry kiln air inlet through pipeline; The work of described control system control dry kiln, and according to the humidity of the temperature in the dry kiln, humidity and the moisture content controlled humidity cryogenic gas that generator is exported that will control, with realization to importing the control of dry kiln gas humidity.
Further, the inlet, outlet place of described dry kiln also is respectively arranged with valve, and described control system is controlled the open degree of dry kiln inlet, outlet by this valve, realizes the control to turnover dry kiln gas flow.
Further, import described humidity generator as source of the gas through pipeline from the described dry kiln waste gas that described thermal energy recoverer is discharged, after waste gas is manufactured the required moisture of system by humidity generator, after the thermal energy recoverer heating, sent back in the dry kiln once more and done work, formed the circulation of whole drying of wood system works gas thus.
Further, described thermal energy recoverer is made of the heat exchanging pipe that is provided with in housing and the inner chamber thereof, housing is provided with two pairs of air inlet/outlets, wherein a pair of is the air inlet/outlet of described heat exchanging pipe, this is used for the turnover of described cryogenic gas to air inlet/outlet, another is to air inlet/outlet and housing intracavity inter-connection, and this is used for the turnover of described dry kiln waste gas to air inlet/outlet.
Further, described humidity generator comprises the housing of enclosed construction, and housing inner chamber bottom is provided with water layer, the middle part is provided with the porous aggregate layer, the packing layer top is provided with spray equipment, and described water layer is that spray equipment supplies water by pump and pipeline, forms the circulation of water in housing; The described dry kiln waste gas of described thermal energy recoverer output is input in the humidity generator through the packing layer below of pipeline from the housing inner chamber, and in packing layer, fully contact, and above packing layer, form after the saturated with moisture gas outlet, top output in the cavity from humidity generator with water under the spray of described spray equipment; Humidity generator has refrigeration and heater, and described control system is controlled the water temperature in the humidity generator by refrigeration and heater, to realize the control to gas humidity that humidity generator is exported.
Further, the described dry kiln waste gas of described thermal energy recoverer output is input in the bottom water of described humidity generator through pipeline, and the gas that enters in the water floats naturally, exports from the gas outlet on humidity generator top after passing described packing layer.
Further, to the pipeline the described thermal energy recoverer, also be provided with gas flow control valve, realize thus passing in and out the further control of described dry kiln gas flow from described humidity generator gas outlet.
Further, described filter comprises the housing of enclosed construction, is perfused with scavenging solution in the housing, and housing is provided with inlet, outlet.
A kind of method for drying wood, be specially: set the drying time of timber, the temperature rise curve in the dry kiln, the flow curve that dry kiln passes in and out gas, the moisture curve that is input to the gas in the dry kiln according to seeds, timber and lumber standards, make dry kiln carry out drying to timber according to the parameters of above-mentioned setting.
Further, described method for drying wood carries out according to tree characteristics and/or timber and lumber standards segmentation, that is: the whole dry run with timber is divided into several time periods, makes dry kiln carry out work according to the moisture curve of different temperature rise curves, gas flow curve, input gas respectively in each time period.
A kind of method for drying wood, be specially: drying time, the temperature rise curve of setting timber according to seeds, timber and lumber standards, make dry kiln according to drying time and the temperature rise curve work set then, and according to the temperature in the dry kiln, humidity and moisture content data, adjust in real time dry kiln turnover gas flow, be input to the humidity of the gas in the dry kiln, the optimum moisture content change curve according to wood to be dried when dry carries out drying to it.
The drying of wood of the present invention system has the following advantages:
