Description

A kind of drying device

The present invention relates to a kind of drying device, relate in particular to and a kind ofly be used for desiccated wood and timber semi-finished product such as glued board or saw a board and the device of other finished product.

As the grove of a kind of wooden perennial plant, broken apart by chopping the back and in timber, contained a large amount of moisture.Known to everybody, in the cell of trees, contain abundant capillary, this capillary contains free fluid and is called as the adsorbed water molecule of moisture, for satisfying the needs that industry is used, this moisture must be reduced to certain standard.Therefore, timber must be through suitably handling, promptly by a kind of method that can prevent multiple seasoning defect drying defect with the drying of wood to certain acceptable final moisture distribution content value.This dry run is referred to as the mayer factor in the economics term.

If timber weather correlated condition is relatively good, just can under the atmosphere natural environment, carries out drying, thereby obtain the quality of acceptable dry sawmilling timber.What must consider is that drying is a very long process in atmosphere, generally needs time several years.After timber is by final drying, just need suitable storage condition to comprise circulation or the like naturally of dry warm air.Must consider that if wood surface is not covered by rainwater, snow or other material, the adsorbed water in the timber will be come out and be evaporated with flowing of surrounding air.Influence the air drying process by piling up the adjustment negotiability again, the reduction that is subjected to the dangerous degree of mould, microorganism, fungi, insect injury (destroying the factor of lumber quality) for timber does not almost have effect.In the air dry run, always there is a potential problem: when and situation that can't prevent unpredictable when the natural air drying takes place, wood deformation can occur.In addition, the mensuration of the moisture abundance in the timber utilizes the air dry technology to carry out according to weather conditions at some cycles after the time, and this just means and occurring time variable in the works, thereby the problem that can cause other is as having increased cost or the like.In addition, also there is other defective in this technology, as low energy consumption, bigger drying area, storage place, security.Can shorten air drying time by the assembling axial fan, all be that axial fan can't influence but also have too many factor as relative humidity etc.

In order to reduce drying time, and take into account cost and quality, developed dissimilar drying equipments: first kind is the compartment type, and second kind is the tunnel drying type of furnace.This drying equipment of two types all is the equipment of fixed type.By first type drying equipment, timber is placed in the compartment, and this compartment can produce the different withering physical conditions that is used for: as temperature, humidity, circulation of air ability etc.By second type drying equipment, timber is down auxiliary horizontal transfer unit, is transmitted through drying equipment, and process is handled under different physical conditions successively, and its purpose is progressively to carry out dry run.Comparatively speaking, the equipment of compartment type is more cheap, but lower than the productive rate of tunnel drying type of furnace equipment, so its cost of investment is also higher relatively.

The drying equipment of known type all has certain defective (will be described in detail following), as bigger cost of investment and consider the difficulty of economic factor on founding the factory.

The technology of now used desiccated wood is that the principle by thermal insulation, convection current, conduction or radiation realizes that low temperature (between 15 to 45 ℃), middle temperature (between 45 to 90 ℃) or high temperature (between 90-130 ℃) carry out drying to timber.

For the drying equipment of certain type, timber is placed in the compartment by suitable means of transportation.By placing the draft fan that (seldom places other places) on the ceiling to produce air stream, under certain situation, can laterally blow, blow but also can level under other situation add laterally, under other situation, can also vertically blow.

The drying equipment that all these are known, its delivery unit constitutes by a kind of mode, and promptly its diameter must be able to satisfy and loads timber as much as possible.Timber in this way of stacking, has air stream along the direction of ventilation stacking at least in a horizontal plane.It is compromise to reach certain between the timber quantity in air gap size (it is necessary flowing for air) and drying oven.In order to quicken dry tenacity, hot-air is blown over by the air gap.When hot-air when highly moist timber contacts, can absorb moisture as much as possible, even also can carry out in the deep of yard.This just means that timber is moist more, and draft fan just must produce strong more air stream, has increased energy consumption thus.Owing to contain a large amount of moisture in air, thereby it may condense on colder place such as furnace wall and other the equipment and causes infringement.Condensate water in drying oven is harmful to for dry run.

As mention a kind of up-to-date drying process in number of patent application EP 0170648A1, its compartment has adiabatic wall.The sawmilling material in drying oven by the longitudinal ventilation stacking.In this drying equipment, be equipped with one and can make air communication cross the draft fan that a heating air register continues also constantly to move in circles by stack wood to a cooling air register then.In heating air register zone, air be heated the back by stack wood to take moisture out of, discharge moisture by the cooling air register to heating air register then.If handle fresh sawmilling, such cohesive process just may produce coagulation.But this process is more suitable for being used to have the timber of the final contact of the timber of low tidal volume-----before industry is used.

If desired, handle extremely moist stack wood, must add hot-air by the mode of saturated air.The discharge of a large amount of saturated airs is accompanied by huge heat loss.Utilize this drying process, its energy utilization ratio is very low.

Except that above-mentioned dry technology, in patent PCT/DK 87/00012 and WO 87/04779, a kind of vacuum drying technique has been described.Wherein, for fear of seasoning defect drying defect, can monitor dry run.The equipment of this use vacuum technique is very responsive for keeping normal vacuum condition, and it is more suitable in the lower timber of dry water content, and this just means the drying process that must first use can remove most of moisture.

For above-mentioned all known methods, can sum up following defectives: as: for global economy be unacceptable lower capacity usage ratio, to the high requirement in occupied ground space, to the higher dependence of the energy, higher seasoning defect drying defect rate, almost do not have an adaptable ability, and it is built to a kind of equipment with fixed type of drying capacity and dry technology, and wherein drying capacity is meant the quantity of desiccated wood.

41,42,43,44, unit ventilators 40, being contained in the exhaust fan 25 on the thermal compression unit and the exhaust fan 71 opened carries out dry run.This system ventilation mouth 111 correspondingly is installed within the walls, closes fire door 11.Thermal compression unit 2 is opened, and produces suitable gas communication under pre-set temperature, and this temperature is to obtain by the

heating element heater

430 and 440 that starts unit ventilators 40.When meeting required condition,

heating element heater

430 and 440 quits work, and this moment, required heat only provided by the thermocompressor 2 that starts.In order to reach the purpose of quickening dry run, must foundation suitably add the circulation of hot-air.In appearing at timber/on moisture when the thermocompressor 2 by absorption of air, at this, utilize compression unit 21 as shown in Figure 8 moisture to be removed and by blast pipe 201 gas is discharged subsequently.In this stage, dry burner hearth 1 links to each other with air outside with 122 by ventilation shaft 121.When by thermocompressor 2, air is heated to uniform temperature and is sucked to circulate by tunnel shape ventilation shaft 1000 by

fan

25,41,42,43, at this, if necessary, gas is heated by suitable

heating element heater

430 and 440, and the air passage 30 of flowing through makes gas enter in the dry furnace chamber 6 by system ventilation mouth 111 and air diverts device 3 then, at this, gas is to import by draft fan 17 according to being deposited in the shape that transmits the timber on the stacked units 50.

This drying condition can effectively be realized moisture from the transmission of timber to ventilating air.By ventilation shaft 122, air is from dry furnace chamber 6 appearance and logical to outside ambient flow.Known on science, the cooling water that is rich in moisture has the trend that flows downward, and therefore is rich in also flowing to the bottom of dry burner hearth 1 than cold air of moisture.Yet, owing to pressure differential occurred simultaneously, utilizing micro climate port 1211, the air of the ventilation shaft of flowing through is replaced by the fresh air that ventilation shaft 121 is contained less moisture.

When the gas of the remainder in dry furnace chamber 6 passes through thermal compression unit 2, utilize compression unit 21, moisture is removed from air, gas partly is heated to temperature required by heating unit 22, utilize all draft fans to make gas enter into the tunnel ventilation well to begin circulation cycle again then.Especially the incipient stage when on the timber/during a large amount of free water of lining appearance, above-mentioned drying mode is a kind of very effective method, it need not to be heated to high temperature and causes the seasoning defect drying defect that may occur in the past the dry run.

Utilize above-mentioned drying process, make in the dry burner hearth 1 and the air humidity in the dry furnace chamber 6 reaches predetermined and controlled value, just must change drying condition.Known to everybody, in the cell of trees, contain capillary, capillary contains free fluid and adsorbed water molecule (being called moisture), if used appropriate drying process, just must under the appropriate climate condition, carry out drying, thereby reduction moisture, these conditions mainly depend on the kind of timber, change with the change of its kind.In addition, moving air always can reduce the moisture content in the timber.

In said method, if used the new drying equipment of this improved, just might in the extremely short time, finish dry run, and need not to assemble any accessory and, also do not need in addition air is additionally heated the accumulation again of timber.Air is opened system ventilating opening 111 as shown in Figure 6 through the passage 30 of contiguous air diverts device 3, considers to need not in most cases additionally air to be heated, even behind defunctionalization, also can finish the dry run of this new improved.When using the drying process of this new improved, micro climate ventilating opening 1211 and

ventilation shaft

121 and 122 are in closed condition.

Thus, this drying process described in the present invention is compared with known dry run technology, and its difference is: need not air and saturated air are carried out flowing repeatedly and mixing, improved the operating efficiency of this new drying process thus.Open the

draft fan

41,42,43,44 of ventilating opening unit 40, the draft fan 25 of thermocompressor 2, and draft fan 71 can produce suitable circulation of air.Extraneous air by system ventilation mouth 111 enter dry burner hearth 1 and and then enter dry furnace chamber 6 and self-regulation ventilating opening 31, the thermocompressor 2 of flowing through subsequently and having heating unit 22, because thermocompressor 2 is not opened under most situations, therefore extraneous air is to utilize draft fan 25 and flow to tunnel shape ventilation shaft 1000, thereby arrives air duct 30.When system ventilation mouth 111 was opened, the air that comes out from air duct 30 can not reenter in the dry furnace chamber 6, but is discharged to the outside atmosphere from dry burner hearth 1.In this way, make drying only to be arranged and ozone can contact with timber.When the technical staff in this field should be understood that and extreme condition occurs, must handle in some way for the live gas that enters, this processing can be by means of accessory mentioned herein, but these changes do not influence principle of the present invention.
