Abstract
A carbonization process for increasing the quality of wood by continuous gradient heating method includes such steps as heating to 120-140 deg.C, eating to 160-240 deg.C, spraying atomized water for slowly cooling to 100 deg.C, filling the saturated steam at 100 deg.C to return the water content back to 4-6%, and cooling to 15-30 deg.C.
Description
Technical field
The present invention relates to a kind of Wood carbonization treatment method, belong to the woodwork technical field of producing.
Background technology
How timber is carried out functionality improvement, it is become the high-quality raw material of high added value woodworks such as production floor, furniture, Development and Production goes out novel woodwork product, benign development for the artificial forest forest zone plantation cause that promotes China, enlarge the raw material sources of numerous wood processing enterprises, reduce raw material and cost of transportation, improve resident's the purchasing power and the market competitiveness of enterprise etc. and have important social meaning, ecological, environmental protective benefit and economic benefit.In existing numerous functionality improvement methods, carbonization of wood treatment technology is because its product size good stability of producing, the corrosion resistant weather resistance is largely increased than unseasoned timber, and the characteristics such as environmentally friendly that do not contain any chemical agent, more and more receive the attention and the concern of wood processing enterprise.
The principle that the carbonization of wood is handled is that timber is placed on the pyrolysis processing of carrying out long-time (usually at 1 to 2 day) in 160 ℃-220 ℃ the environment, by reducing the concentration of hydroxyl in the wood components, reduce the hygroscopicity and the internal stress of timber, thereby reach the purpose that increases the Wood Dimensional Stability energy; Complicated chemical reaction has taken place in wood components in the charing heat treatment process simultaneously, changed some composition of timber, reduced the nutriment of wood-decaying fungus, suppress the growth of mushroom timber from this link of food chain, the complex chemical reaction that takes place in the timber also produces some toxin harmful to rot fungi, can kill rot fungi, improve the corrosion resistant weather resistance of timber.Because carbonization of wood treatment process still in conceptual phase, has the lumber quality instability of PROCESS FOR TREATMENT now, is easy to generate the quality problems of distortion, and the cycle that charing is handled is long, improved production cost greatly, so result of use is unsatisfactory.
Summary of the invention
The objective of the invention is to: provide a kind of cycle of handling to lack, reduce production costs, process the good Wood carbonization treatment method of lumber quality that obtains, to overcome the deficiencies in the prior art.
The present invention is achieved in that this method comprises the steps,
A, press 1t/m with the neat piling of timber and at timber heap top
2Standard compression steel plate frame pouring concrete briquetting, in the carbonization of wood equipment of packing into then;
B, in carbonization of wood equipment, adopt the continuous temperature-rising method of staged, temperature is warming up to 120～140 ℃ by the speed that improved 3～7 ℃ in per 4～6 hours;
C, adopt the continuous temperature-rising method of staged, the speed that improved 8～12 ℃ by per 1～3 hour is warming up to 160～240 ℃, and keeps under maximum temperature 3～6 hours, and the charing processing procedure finishes; When temperature raises, improve 8～12 ℃ rapidly and kept 2 hours later on, after temperature reaches maximum temperature, under this temperature, kept 3～6 hours.
D, treat that the charing processing procedure finishes, stop heating, adopt atomization water method to allow timber slowly be cooled to 100 ℃, the saturated steam that feeds 100 ℃ then carries out damping moisture regain processing to timber, in 6～8 hours processing times, the moisture content of timber is adjusted back 4～6%;
E, timber are cooled to temperature under field conditions (factors) and are higher than kiln discharge after 15～30 ℃ of the room temperatures.
Above-mentioned Wood carbonization treatment method in step b, adopts the continuous temperature-rising method of staged in carbonization of wood equipment, temperature is warming up to 130 ℃ by the speed that improved 5 ℃ in per 5 hours.
Above-mentioned Wood carbonization treatment method in step c, adopts the continuous temperature-rising method of staged, and the speed that improved 10 ℃ by per 2 hours is warming up to 160～240 ℃, and keeps under maximum temperature 4～5 hours, and the charing processing procedure finishes.
The charing of adopting method of the present invention to carry out timber is handled, and has the advantage of following several respects:
1, adopt stepped continuous temperature-rising method, can prevent that timber from producing defective in processing procedure, it is good to handle the lumber quality that obtains.
2, handle no chemical contamination, the charing processing cycle is short, reduces production costs, and has advantages such as efficient, energy-conservation.
3, the method quickening timber cooling rate that the back temperature-fall period adopts atomization water is handled in charing, promptly can shorten the production cycle, improve utilization rate of equipment and installations, and this process can also significantly be eliminated the inner stress that forms of drying and charing processing back sheet material.
4, the timber after utilizing 100 ℃ saturated steam that charing is handled carries out the damping moisture regain and handles, and the sheet material of moistening overdrying is adjusted back 4-6% with the moisture content of sheet material fast and effectively, is beneficial to the following process process and carries out smoothly.
The specific embodiment
Embodiments of the invention: the present invention includes following step,
A, press 1t/m with the neat piling of timber and at timber heap top
2Standard compression steel plate frame pouring concrete briquetting, in the carbonization of wood equipment of packing into then.
B, timber are packed into behind the charing equipment, begin to heat up.The continuous temperature-rising method of the phase I employing staged that heats up, temperature is warming up to 130 ℃ by the speed that improved 5 ℃ in per 5 hours, promptly keep 5h after 5 ℃ heating up on the original temperature basis rapidly, temperature is raised to high 130 ℃ with identical method then, be incubated 5h under 130 ℃ of conditions, first temperature rise period finished.The timber kind difference of processing, its maximum temperature is determined according to the density of wood size, the little temperature height of density, the big temperature of density is low, and the maximum temperature of various timber is set according to prior art.
After c, first temperature rise period finish, entered for second temperature rise period.Second temperature rise period was adopted the continuous temperature-rising method of staged, speed by 10 ℃ of raisings in per 2 hours is warming up to 210 ℃, promptly keep 2h after 10 ℃ heating up on the original temperature basis rapidly, temperature is raised to high 210 ℃ with identical method then, and under 210 ℃ of temperature, kept 4 hours, the charing processing procedure finishes.
D, treat that the charing processing procedure finishes after, close the heating valve of charing treatment facility, stop heating, opening the atomized water device valve, jet atomization water in charing equipment is cooled to 100 ℃ to timber with atomization water, and the saturated steam that feeds 100 ℃ then in charing equipment carries out damping moisture regain processing to timber, in 6 hours processing times, the moisture content of timber is got damp again 6%.
E, timber is naturally cooled to temperature at last in charing equipment and be higher than kiln discharge after 15～30 ℃ of the room temperatures.
