Description
Title of the invention: Modular wood drying installation
[0001] The present invention relates to a modular wood drying installation.
[0002] It finds a general application in the drying of wood on production sites, and more particularly in the limitation of energy consumption in wood drying.
[0003] Much progress has been made in the field of wood drying, but the drying activity still remains to this day an activity whose energy balance has an ecological impact.
[0004] Indeed, the problem of improving the quality of dried wood generally requires increasing the energy impact of said drying activity.
[0005] Drying systems of the container or motorized drying box type forming a frame are known, and having a system for drying coarse bulk materials, such as wood chips, logs or grain. These systems include a heat pump with accessory condensers and evaporators to better control drying and the energy consumed.
[0006] These wood drying systems have the disadvantage of presenting a costly energy loss, and do not allow to ensure that the drying of the wood allows a fine regulation to avoid glazing or a fracture of said wood to be dried and thus obtain a structurally qualitative wood, and are all the more expensive to manufacture.
[0007] Tubular drying systems are also known that are equipped with an energy-saving heating module, such as a heat pump, for heating and cooling. With the cooling system, the moisture leaving the wood is condensed and the resulting heat is used to heat the installation. The system is completed by a buffer tank, which stores part of the energy used during drying for reuse in the next cycle.
[0008] Such tubular drying systems have the disadvantage of requiring high-power heat pumps to support drying, and their drying energy performance varies greatly depending on the environment in which said drying system is used.
[0009] This problem is all the more important in cold and humid countries, since the power required to heat and maintain a stable temperature during drying is all the more important when the external temperatures are low, and requires excess energy consumption while exposing the wood to be dried to drying defects.
[0010] Such tubular and container-type systems also have the disadvantage major drawback of not having advanced regulation of internal drying conditions, which leads to a disparity in the quality of drying on the same batch of wood to be dried, and does not allow for wood to be uniformly exposed to the same internal drying conditions.
[0011] The present invention overcomes these drawbacks.
[0012] The invention relates to a modular wood drying installation of the prefabricated closed container type, comprising: - -a thermally insulated containment module, capable of accommodating wood to be dried, having opening / closing means forming a door, and whose internal volume forming a drying environment is configured to be heated - heating means configured to heat the internal volume of the containment module forming a drying environment; and - air mixing means configured to thermally standardize the drying environment. According to a general definition of the invention, the modular drying installation comprises: -a first external thermal insulating assembly configured to thermally insulate the internal volume while providing wear resistance limiting the variation in the thermal insulation capacity associated with said first external insulating assembly; - a second internal insulating assembly, arranged on the internal face of the first external insulating assembly, capable of preventing the diffusion of water vapor towards the outside of said confinement module; in that the first and second insulating assemblies are uniformly distributed around the internal volume of the containment module, the opening / closing means forming a door also comprising a uniform distribution of the first and second insulating assemblies over the entire surface of the door; and in that the heating means comprise a closed circuit, configured to inject hot air into the internal volume and extract hot humid air from the internal volume, to enable water extraction, heating and reinjection of the dehumidified air into the drying environment.
[0013] Surprisingly, the installation according to the invention allows for efficient insulation, adaptable to the environment and uniform, which in combination with drying and air distribution means, allows the drying environment to be standardized and finely controlled while drastically reducing any loss of thermal energy, regardless of the external environment in which the drying installation is installed.
[0014] Furthermore, such a system allows for the reduction of manufacturing costs of a drying installation while allowing it to be easily deployed.
[0015] In practice, the first external insulating assembly is tripartite comprising an external vapor-proof layer that is airtight and watertight, and a thermally insulating inner honeycomb layer, comprising an alternation of refraction means and a thermally insulating material, said first external tripartite insulating assembly having a first chosen thermal diffusivity coefficient XI and a chosen thickness E1 and having a first chosen diffusivity coefficient XI less than or equal to 0.045 W / mK
[0016] In practice, the second internal insulating assembly comprises a thermally insulating layer, defined by a second chosen thermal conductivity coefficient X2 less than or equal to 0.045 W / mK and of a chosen variable thickness E2, and a vapor barrier layer oriented towards the internal volume of the confinement module.
[0017] By way of non-limiting example, the thermally insulating layer of the second internal insulating assembly comprises an insulating material of the sandwich panel type.
[0018] According to another non-limiting example, the thermally insulating material of the internal honeycomb layer of the second internal insulating assembly belongs to the group of thermally insulating materials of the polyethylene foam type.
[0019] In practice, the heating means comprise at least one heat pump having an evaporator capable of extracting thermal energy from outside the drying system, and a capacitor capable of transferring the thermal energy extracted from the outside environment to the drying environment.
[0020] According to an embodiment in accordance with the invention, the heat pump type heating means further comprise at least one accessory capacitor configured to promote the transfer of thermal energy from the heat pump to the drying environment.
[0021] According to another embodiment in accordance with the invention, the heat pump type heating means further comprise at least one accessory evaporator configured to promote the extraction of heat from the environment outside said drying installation.
[0022] These two embodiments can be combined with each other.
[0023] In practice, the installation according to the invention further comprises meteorological monitoring means, configured to measure and record selected meteorological parameters of the internal volume of the containment module forming the drying environment and of the wood to be dried.
[0024] By way of non-limiting example, the meteorological parameters monitored and recorded by meteorological monitoring means belong to the group formed by: temperature of the internal volume of the containment module, humidity of the internal volume of the module confinement, temperature and humidity at the heart of the wood to be dried, temperature and humidity at the surface of the wood to be dried, pressure in the internal volume.
[0025] In practice, the drying installation according to the invention further comprises opening / closing means, the entire surface of which comprises the first and second insulating assemblies.
[0026] In addition, the opening and closing means have a pneumatic seal arranged at the contact areas with the containment module, and configured to maintain complete sealing of the drying environment.
[0027] Advantageously, such a distribution allows uniform performance insulation at any point in the containment module.
[0028] In practice, the installation according to the invention comprises an energy performance coefficient greater than or equal to two.
[0029] Advantageously, such an operating mode always makes it possible to ensure that the total energy balance of the installation is optimized.
[0030] In practice, the containment module is of the prefabricated container type.
[0031] The Applicant observed that such a format offered an easy movement and deployment capacity in any area while providing a solid framework resistant to various external conditions.

[0039] [Fig.7] schematically represents the drying installation in operation in accordance with the invention.
[0040] With reference to figures 1 to 7, the modular drying installation according to the invention comprises a thermally insulated containment module 1, comprising an internal volume 11 forming a drying environment capable of accommodating wood to be dried 100, heating means 2 configured to heat the internal volume 11 of the containment module 1 forming a drying environment, and air mixing means 3 configured to thermally standardize the drying environment.
[0041] The containment module 1 is composed of a structural cladding 12 forming the outer surface layer of said containment module 1.
[0042] In practice, the structural cladding 12 is of the prefabricated container type.
[0043] Advantageously, a container-type format makes it easier to move and set up the drying installation using standard lifting means and thus modulate the position of said installation as close as possible to the wood production areas.
[0044] The drying installation further comprises an aluminum frame fixed to the internal face of the structural cladding 12, having an external face 13A and an internal face 13B, said external 13A and internal 13B faces delimiting an interstitial space capable of accommodating a first tripartite external insulating assembly 4, and a second internal insulating assembly 5.
[0045] In practice, the interstitial space is uniformly formed over the entire internal surface of the structural cladding 12.
[0046] The first tripartite external insulating assembly 4 of the confinement module is arranged in contact with the external face 13A of the frame, and has an external vapor-proof layer 41 which is airtight and waterproof, and a thermally insulating internal honeycomb layer 43.
[0047] The first tripartite external insulating assembly 4 is defined by a first chosen thermal conductivity coefficient XI and a chosen thickness El.
[0048] The thermal conductivity coefficient X is defined as the capacity of a material to diffuse heat in the media without macroscopic movement of matter. It is the ratio of the thermal energy (quantity of heat) transferred per unit of time (therefore homogeneous to a power, in watts) and surface to the temperature gradient.
[0049] In practice, the chosen thermal diffusivity coefficient XI is less than or equal to 0.045 W / (mK).
[0050] By way of non-limiting example, the first tripartite external insulating assembly 4 has a thickness E1 of 40 mm.
[0051] In practice, the internal honeycomb layer 43 comprises an alternation of refraction means 45 and a thermally insulating material 44.
[0052] According to one embodiment, the refraction means 45 are arranged parallel to the structural cladding 12.
[0053] Furthermore, the thermally insulating material 44 of the inner honeycomb layer 43 is arranged between the refraction means 45 in the form of a zig-zag structure. configured to allow the presence of interstitial spaces forming cells allowing the presence of air in said first tripartite external insulating assembly 4.
[0054] By way of non-limiting example, the thermally insulating material 44 of the internal honeycomb layer 43 of the first external insulating assembly 4 belongs to the group of thermally insulating materials of the polyethylene foam type.
[0055] The Applicant observed that the structure of the first external insulating assembly 4 makes it possible to thermally insulate the internal volume 11 of the confinement module 1 in an efficient manner while minimizing the impact of weather conditions and temperature variations around the drying installation on the average temperature of the internal volume 11.
[0056] Advantageously, the first external insulating assembly 4 also makes it possible, in particular thanks to its vapor barrier layer and its composition, to constitute a lightweight assembly, with a long service life, and with resistance to wear, so that degradation linked to weather conditions is reduced so that the variation in the thermal insulation capacity associated with said first tripartite external insulating assembly 4.
[0057] The confinement module 1 further comprises a second internal insulating assembly 5, arranged between the internal face of the first external insulating assembly 4 and the internal face 13B of the frame.
[0058] Said second internal insulating assembly 5 comprises a thermally insulating layer 51, as well as a vapor barrier layer 52 oriented towards the internal face 13B of the frame, and configured to prevent the diffusion of water vapor towards the outside of said confinement module 1.
[0059] The second internal insulating assembly 5 further has a second chosen thermal diffusivity coefficient / .2 and a chosen variable thickness E2.
[0060] In practice, the chosen thermal diffusivity coefficient / .2 is less than or equal to 0.045 W / (mK).
[0061] By way of non-limiting example, the second internal insulating assembly 5 has a thickness E2 of between 40 mm and 80 mm.
[0062] Depending on the weather conditions in the area of use of the drying installation according to the invention, the thickness E2 is variable.
[0063] As a non-limiting example, a thickness of 40 mm will be indicated for areas where the lower temperatures are greater than 5°C, and a thickness of 80 mm for areas where the lower temperatures are of the order of 5°C to -10°C.
[0064] By way of non-limiting example, the thermally insulating layer 51 of the second internal insulating assembly 5 comprises an insulating material of the sandwich panel type.
[0065] A sandwich panel is understood to mean a panel consisting of an insulating polyurethane foam forecourt between two re-lacquered galvanized steel sheets.
[0066] Advantageously, such a variation in thickness makes it possible to standardize the power. minimum and maximum heating means and thus stabilize the energy consumption of the installation for a given external environment and thus allow the drying installation to be adaptable to the environment in which it is installed.
[0067] The Applicant observed that the vapor barrier layer 52 oriented towards the internal face 13B of the frame, and configured to prevent the diffusion of water vapor towards the outside of said confinement module 1, makes it possible to protect the two insulating assemblies 4, 5 from the conditions of the internal volume 11 during drying, which is saturated with water vapor and other agents, and from the external environment, thus making it possible to extend the period of thermal insulation effectiveness.
[0068] In practice, the first and second insulating assemblies 4, 5 are uniformly distributed around the internal volume 11 of the confinement module 1 so that the internal volume 11 has uniform insulation at 360° so that the thermal energy transferred by the heating means 2 and distributed by the air mixing means 3 is uniform, or almost uniform over the whole of said internal volume 11.
[0069] Advantageously, such uniformity of temperature distribution makes it possible to obtain uniform and quality drying, and helps to minimize any macroscopic damage to the dried wood linked to too great a temperature difference between two points in a batch of wood to be dried.
[0070] The containment module 1 further comprises opening / closing means forming a door, configured to allow access to the internal volume 11 in the open state and thus insert or extract the wood 100 subject to drying, and seal said internal volume 11 in the closed position to allow control of the drying environment.
[0071] In practice, the opening / closing means comprise at least one door.
[0072] According to a particular embodiment of the invention, the door comprises two pivoting flaps, each around a vertical axis.
[0073] In practice, the entire surface of the opening / closing means comprises a framework in which the first and second insulating assemblies are fixed under the same conditions as the rest of the confinement module 1.
[0074] According to a particular embodiment of the invention, the opening and closing means have at least one pneumatic seal arranged at the contact zones with the rest of the containment module, configured to maintain complete sealing of the drying environment and thus contribute to the uniformity of the thermal insulation around the internal volume 11 forming the drying environment.
[0075] Furthermore, such an arrangement allows better control of the internal temperature of the containment module 1, with minimal heat loss, and thus improves the operating energy balance of the drying installation.
[0076] The drying installation further comprises heating means 2 energized technically optimized and heating the internal volume in which the heated injected and evacuated air circulates in a closed circuit.
[0077] In practice, the heating means 2 comprise at least one heat pump 21.
[0078] Each heat pump 21 has an evaporator 22 capable of extracting thermal energy from outside the drying system by heat extraction via a chosen heat transfer agent, and a condenser 23 capable of transferring the thermal energy extracted from the outside environment to the drying environment.
[0079] By way of non-limiting example, the heat transfer agent is R513a.
[0080] According to a particular embodiment of the invention, several heat pumps 21 can be mounted in cascade so as to increase the power delivered in the internal volume.
[0081] According to a first particular embodiment of the invention, each heat pump 21 comprises at least one accessory capacitor 24 configured to promote the transfer of heat from the heat pump 21 to the drying environment.
[0082] According to a second particular embodiment of the invention, each heat pump 21 further comprises at least one accessory evaporator 25 configured to promote the temperature drop to efficiently collect calories from the environment outside said drying system.
[0083] According to a third particular embodiment of the invention, each heat pump 21 further comprises at least one accessory evaporator 25 and at least one accessory capacitor 24.
[0084] In practice, the heating means 2 comprise at least one heat pump 21, the extracted heat energy from which is transferred in the form of thermal energy by at least one of the capacitors 23, 24 in a heat exchange zone to a hot air circulation module 14 connected to the internal volume 11.
[0085] The hot air circulation module 14 has a closed-loop duct equipped with heating resistors 26, configured to compensate for drops in heat extraction in the event of excessive variations in the temperature outside the drying installation, said hot air circulation module 14 further comprising hot air injection means 29.
[0086] In practice, the hot air injection means 29 are constituted by at least one fan allowing the circulation of hot air from the heat pump 21 to the internal volume 11 forming the drying environment of the wood to be dried 100 in said hot air circulation module 14.
[0087] Advantageously, the heat pump(s) 21 in combination with the hot air circulation module 14 allows the injection of hot air into the internal volume at hy constant grometry. Such a technical advantage also makes it possible to avoid the use of a humidification line in containment module 1.
[0088] The Applicant also observed that the injection of hot air at constant hygrometry makes it possible to obtain homogeneity of the ambient air of the drying environment, and consequently homogeneity of drying in the internal volume 11.
[0089] Furthermore, due to the homogeneity of drying, the wood to be dried deforms little during the drying operation.
[0090] The hot air circulation module 14 further comprises an exhaust duct configured to allow the circulation of air from the drying environment to the heat exchange zone of the heat pump(s) 21.
[0091] In practice, the hot air circulation module 14 further allows the evacuation of hot air saturated with water vapor during a wood drying operation, further allowing the heat pump 21 to be used as a means of condensing said water vapor to allow the separation of the accumulated drying water and the reinjection of the air into the heating means 2 to be injected again into the internal volume 11.
[0092] In practice, the drying installation comprises a condensation tank 15 configured to receive the water condensed from the water vapor present in the air extracted from the internal volume, and to evacuate the water from said installation.
[0093] According to a particular embodiment of the invention, the hot air injection means 29 are configured to allow a variation in the circulation speed of the hot air in the circulation mode. Advantageously, the combination of a heat pump 21 and the hot air circulation module 14 makes it possible to control the humidity of the air injected into the internal volume 11, and to control the extraction of the humidified air from the drying environment.
[0094] The drying installation according to the invention further comprises meteorological monitoring means 6, configured to measure and record selected meteorological parameters of the internal volume of the containment module forming the drying environment and of the wood to be dried.
[0095] In practice, the meteorological parameters monitored and recorded by meteorological monitoring means belong to the group formed by temperature of the internal volume of the containment module, humidity of the internal volume of the containment module, temperature and humidity at the heart of the wood to be dried, temperature and humidity at the surface of the wood to be dried, pressure in the internal volume 11, or a combination of the aforementioned parameters.
[0096] In practice, the metrological monitoring means comprise at least one temperature probe, one probe for measuring the humidity of the internal volume 11, at least 3 humidity measuring probes and at least 3 temperature measuring probes in surface and core of the wood to be dried 100, so as to precisely follow the drying operation.
[0097] Advantageously, a measurement of the humidity and temperature on the surface of the wood to be dried and in its core allows regulation of the drying conditions by the control unit based on the hygrometry / humidity threshold of the wood, which also allows retro-regulation of the activity of the heating means 2 and of the hot air circulation module 14.
[0098] The Applicant also observed that measuring the temperature and humidity on the surface and at the core of the wood made it possible to avoid the phenomenon of glazing of the surface part of the wood to be dried 100, the glazing forming a crust on the wood and preventing the water at the core from escaping.
[0099] As a non-limiting example, the meteorological monitoring means 6 allowing temperature monitoring belong to the PT 100 probes.
[0100] As a non-limiting example, the meteorological monitoring means 6 allowing humidity monitoring belong to the EMC probes.
[0101] According to an optimal embodiment of the invention, the metrological monitoring means 6 arranged in the confinement module 1 comprise n PT 100 probes and n EMC probes arranged transversely and radially on the internal surface of the confinement module 1, in a regular manner and in the corner-type dead points (critical values), where n is an integer greater than 1.
[0102] By way of non-limiting example, the metrological monitoring means 6 further comprise at least one probe for measuring the pressure in the internal volume 11 of the confinement module 1.
[0103] Advantageously, measuring the pressure in the internal volume 11 of the containment module makes it possible to ensure that the drying environment is always less than or equal to atmospheric pressure, so as to maximize the extraction of water from the wood to be dried.
[0104] According to a particular embodiment of the invention, the drying installation further comprises overpressure flaps configured to discharge excess pressure beyond a defined threshold.
[0105] The drying installation according to the invention further comprises air mixing means 3, arranged in a high position in the internal volume 11 of the confinement module and configured to mix the hot air in the drying environment and thus standardize the temperature in the internal volume 11.
[0106] According to a particular embodiment, thermal reflectors are arranged on any angular surface of the internal volume 11 of the confinement module in order to reduce the temperature variations between the critical points such as the corners and the rest of the internal volume 11.
[0107] The energy performance coefficient is defined as the ratio between energy produced and energy expended by the installation.
[0108] The Applicant also observed that such a combination of technical means allows the drying installation to maintain an energy performance coefficient greater than or equal to two under all conditions.
[0109] For example, the drying installation makes it possible to maintain an energy performance coefficient greater than or equal to 3, greater than or equal to 3.5, or greater than or equal to 4.
[0110] Furthermore, the energy performance coefficient COP depends on the outside temperature, the heat output supplied by the heating means 2 and the power absorbed.
[0111] In a closed circuit, the energy performance coefficient COP is asymptotic because it is the ratio of heat power supplied / power absorbed by said heating means 2 which leads to variations.
[0112] Advantageously, the drying installation according to the invention makes it possible to ensure fine regulation of the drying of the wood to avoid glazing or fracture of said wood to be dried and thus obtain structurally high-quality wood.
[0113] The Applicant also observed that the drying installation in accordance with the invention makes it possible to stabilize the drying energy performance and thus reduce the variations in said drying energy performance linked to the external conditions in which the drying installation is used.
[0114] Finally, the combination of special insulation and fine regulation of heating and energy expenditure, while ensuring uniformity of the internal drying environment, makes it possible to limit the disparity in the drying quality on the same batch of wood to be dried, and makes it possible to have wood uniformly exposed to the same internal drying conditions, said wood drying operations not sacrificing the total energy balance in favor of the quality or speed of drying.
