Abstract
The present invention relates to a kind of drying method of timber.Hot-tub with the dimension board that cuts or square bar place 40-60 ℃ soaked 3-5 days, placed under the normal temperature empty water then 1 day, placed in 60-65 ℃ the drying kiln again, kept getting final product in 10-12 days; In the calandria radiator 5 of underground heat circulating water flow through being installed on the kiln top, open blower fan its out temperature is controlled between 61-72 ℃, and the control kiln temperature is between 60-65 ℃.This technology has shortened arid cycle, makes dried timber, quality even, the soft or hard appropriateness, and saved a large amount of energy, reduced the pollution of environment.
Description
The present invention relates to a kind of drying method of timber.
Timber plays a part very important in the development of the national economy.Owing to contain a large amount of moisture content in the timber, through cutting out, be processed into the sheet material of all size after, also will be through oven dry, processing such as typing just can be used.The processing technology of traditional desiccated wood is: utilize air in electricity, coal, the wet goods heat drying stove, then timber is placed the cylinder-drying kiln inner drying, make the water content reduction of timber reach instructions for use.The method of this desiccated wood had both been wasted the energy, had prolonged the drying time of timber again, and dry quality is also bad, was prone to the phenomenon of drying mark.As adopting electrical heating, some dry every cubic metre of timber need expensive 300 yuan of left and right sides RMB, and the coal-fired drying equipment of equipment input ratio increases by 40%.If adopt coal-fired drying, then dry mass is poorer, and the dried timber color and luster deepens, dense, the drying mark of coal smoke flavor, and working strength of workers is big, and auxiliary device is also many.
The object of the present invention is to provide a kind of method of utilizing the geothermal water desiccated wood, both placed hot water to soak in timber, naturally empty then water is put into by the dry kiln drying of the air of GEOTHERMAL WATER heating again, can reach effect energy-conservation and the raising wood drying quality.
The objective of the invention is to realize through following technical measures:
This method comprises the drying means and the formation of technical process and drying kiln:
A, its technical process be, dimension board or the square bar that cuts placed 40-60 ℃ hot-tub, soaked 3-5 days, placed under the normal temperature empty water then 1 day, places in 60-65 ℃ the drying kiln again, keeps getting final product in 10-12 days;
The drying means of b, its drying kiln is with in the calandria radiator 5 of underground heat circulating water flow through being installed on the kiln top, opening blower fan is controlled at its out temperature between 61-72 ℃, and the control kiln temperature is between 60-65 ℃, the degree of saturation of looking furnace air is opened the steam vent on the kiln wall, each about one hour, regularly measure timber moisture content, make it water content and reduce to below 10%;
The formation of c, its drying kiln is that radiator 5 is placed on the roof in the kiln body 1, and is furnished with blower fan, the delivery pipeline is connected in the import and export of radiator 5, bottom at radiator 5 is provided with horizontal baffle, leave the gap with wall around the deflection plate, kiln body 1 sidewall is provided with the steam vent 3 that can open, and whole kiln body is provided with heat-insulation layer, inwall scribbles waterproofing agent and anticorrosive paint.
Advantage of the present invention and good effect are:
1. the thermal source of dry kiln has adopted the mode of hot water calandria radiator, thereby equipment drops into fairly simple.The Hot water immersion method that adopts can make organic acid, resin substitution in the timber thorough, and dry rear defence tidal energy power strengthens, and mothproof characteristics are arranged.
2. this technology has shortened arid cycle, and the timber water content is reduced in about 8%.Improved dry mass, made that product is not yielding, cracking, free from extraneous odour, intensity have no effect.
3. this process makes dried timber, and quality is even, soft or hard is appropriate, has increased machinability.And this process has been saved a large amount of energy, has reduced the pollution of environment.
Description of drawings is as follows:
Accompanying drawing of the present invention is a GEOTHERMAL WATER heat radiator type drying kiln perspective view.
Below in conjunction with drying kiln structure shown in technical process and the accompanying drawing, the present invention is done further detailed description.
At first script specification on demand is cut into sheet material or square bar, the hot-tub that places cement to make, generally can control water temperature between 40-60 ℃, adopt geothermal water, soaked 3-5 days, make it fully to soak into, pull empty 1 sky and water under the natural environment of normal temperature then out, delivered in the drying kiln by special cart, baking is 10-12 days under 60-65 ℃ environment, gets final product kiln discharge again.This drying kiln is made by cement, at Yao Ding, ground and wall heat-insulation layer is housed all, calandria radiator 5 is placed the top within doors of kiln body 1, the GEOTHERMAL WATER out temperature is controlled between 61-72 ℃, dry in kiln by blower fan, baffling through the roof horizontal baffle makes hot-air formation convection current in the kiln, when furnace air reaches the saturated shape of heat steam, open the steam vent 3 on the kiln wall, exhaust one hour, circulation is more than, total kiln temperature that keeps is between 60-65 ℃, through 10-12 days time, record the timber water content below 10%, keep a period of time to get final product kiln discharge.Inwall at kiln body 1 scribbles waterproofing agent and anticorrosive paint, prevents efflorescence and bacterial reproduction after the kiln interior wall humidity, increases its durability.The drying kiln body be furnished with temperature automatically controlled exhaust control device, and carry machinery, the electric utilities such as water pump of geothermal water, be installed in the control room 2 of kiln side.Transport the track of timber in addition with gate 4 corresponding grounds of kiln, timber is sent into or pulled out in the kiln for special cart.
With kiln internal volume 31.60m
3Meter, stackable timber 15m
3, heat exchange area reaches 120m
3, select compressor flow 12000m
3/ h, hot water flow 10t/h, wind speed 1.4-2m/sec between plate, power of fan 1.5KW, heat hydraulic pressure 0.04MPa.Handle same timber relatively with the electrothermal drying method, one cubic metre of timber, 100 degree that can economize on electricity, energy savings 70-80% and coal-fired drying means relatively, 500kg can economize on coal.Therefrom visible its economic benefit and social benefit are appreciable.
