Definitions
- the present invention belongs to the general field of manufacturing thermal and/or acoustic insulation products. It relates more particularly to a system for crosslinking a continuous mat of mineral and/or plant fibers, in particular mineral wool, of the glass or rock wool type. Such a mattress is intended to be cut to then form, for example, thermal and/or acoustic insulation panels or rolls.
- the invention also relates to a crosslinking method implemented by means of such a crosslinking system.
- the manufacture of insulating fiber mats primarily comprises fiberizing and depositing fibers on a conveyor or perforated mobile conveyor.
- the newly formed pile of fibers is placed on the conveyor using suction boxes arranged under the conveyor on which they are deposited.
- a binder is sprayed in the state of solution or suspension in a volatile liquid such as water onto the stretched fibers, this binder having adhesive properties and usually comprising a heat-curable material, such as a thermosetting resin.
- the primary layer of relatively loose fibers on the collecting conveyor is then transferred to a heating device commonly referred to in the art as a crosslinking oven.
- a heating device commonly referred to in the art as a crosslinking oven.
- the continuous mat of fibers crosses the oven over its entire length, thanks to conveyors facing one above the other, pressing the mat between them, and whose spacing distance is adjustable.
- Such a mattress thus has a greater or lesser density depending on the degree of compression exerted by the two conveyors in the oven.
- the mattress is simultaneously dried and subjected to a specific heat treatment which causes the polymerization (or “hardening”) of the thermosetting resin of the binder present on the surface of the fibers.
- the procedure used to cause the binder to harden consists of passing heated air through the entire thickness of the mattress, in such a way that the binder present throughout the thickness of the mattress is itself gradually brought to a temperature higher than its curing temperature.
- the reticulation oven is made up of an enclosure constituting a closed chamber in which a series of boxes are arranged. Each box is supplied with hot air by a combustion chamber to which at least one burner is attached as well as fans allowing respectively to supply air to said at least one burner and to circulate the hot air produced by it. .
- the present invention aims to remedy all or part of the drawbacks of the prior art, in particular those set out above, by proposing a solution which makes it possible to manufacture, in a secure manner, a mattress of insulating fibers by reducing the quantity of gas consumed in comparison with state-of-the-art solutions, and while maintaining excellent energy efficiency.
- the present invention therefore makes it possible in particular to respond to current environmental preservation constraints in that it offers the possibility of limiting the release of greenhouse gases during the manufacture of an insulating fiber mattress.
- the invention relates to a system for crosslinking a continuous mattress of mineral and/or plant fibers, comprising an oven for crosslinking said mattress comprising at least one heating box, each heating box being connected to a combustion chamber.
- Said crosslinking system further comprises a so-called “injection” system arranged outside the crosslinking oven and configured to inject hot air into at least one combustion chamber of a heating box, hot air thus injected replacing a given fraction of hot air produced by at least one burner attached to said at least one combustion chamber, said fraction being between 20% and 100%, for example between 30% and 95%, more particularly between 40% and 80%.
- the plant fibers are preferably chosen from the group consisting of lignocellulosic fibers and cotton fibers.
- the lignocellulosic fibers are preferably chosen from wood fibers, hemp fibers, linen fibers, sisal fibers, cotton fibers, jute fibers, coconut fibers, raffia fibers, abaca fibers, cereal straw or rice straw.
- the hot air injected into a combustion chamber by means of the injection system replaces part of the hot air which would be produced (nominally) by at least one burner without external energy supply (i.e. the hot air circulating in a heating box and produced exclusively from gas used by at least one burner, or in other words, the hot air produced by at least one burner before the injection system is put into operation) .
- the choice of the value of said fraction may depend on the way in which the crosslinking system is intended to be operated.
- the value of the fraction can be set so that the flow rate of hot air injected via said injection system replaces (substitutes) part of the nominal flow rate of hot air circulation at the within said at least one heating box.
- the control of the injection system, and therefore a fortiori the choice of the value of said fraction can be carried out according to still other considerations, such as for example considerations in terms of energy or power provided by the at least one burner of said at least one heating box (i.e. we aim to replace (substitute) part of this energy/power thanks to the hot air injected with the injection system).
- the operational safety of the reticulation oven is guaranteed thanks to this supply of hot air which sweeps the heating box(es).
- the invention offers the advantageous possibility of limiting gas consumption, and therefore ultimately limiting the release of greenhouse gases.
- hot air produced from so-called “green” electricity i.e. electricity produced from energy that emits little CO2, such as renewable energies or even nuclear energy.
- the inventors notably estimated that the gas requirement for a crosslinking oven could be reduced by 50% to 70% thanks to the invention, which induces a substantial quantity of greenhouse gases not released into the atmosphere.
- This possibility of reducing the need for gas is also advantageous in that it makes it possible, a fortiori, to limit the production of combustion gases inside the oven. This therefore contributes to reinforcing the safety of use of the crosslinking system, it being understood that such combustion gases can accumulate in addition to releases linked to the binder used.
- Yet another advantage of the invention lies in the fact that the injection system can be easily installed on an existing fleet.
- the injection system can be positioned on the ground next to the reticulation oven enclosure, or even higher up, for example on a dedicated walkway.
- the external position of the injection system makes it possible to protect it from any pollution (example: release of particles) generated by the crosslinking oven, such pollution being able to cause clogging capable of limit its effectiveness, or even be fatal to its operation, and therefore possibly cause operating safety problems (example: fire in the case of dirty electrical resistance).
- any pollution example: release of particles
- the crosslinking oven such pollution being able to cause clogging capable of limit its effectiveness, or even be fatal to its operation, and therefore possibly cause operating safety problems (example: fire in the case of dirty electrical resistance).
- the crosslinking system according to the invention finds a particularly advantageous application in the case of the use of biosourced binders. Indeed, due to the injection of hot air, the cooking air is drier, which allows a considerable part of the dilution water used to make the biosourced binder to be sprayed onto the fibers of the mattress to be evacuated. . This advantage also applies in the case of a binder obtained by esterification reaction, where a very large part of the water resulting from the reaction can be evacuated. In other words, the invention makes it possible to gain in drying/cooking capacity (and therefore even more in energy and limitation of CO2 emissions).
- biosourced binder reference is made here to a binder partially or totally derived from biomass. This is for example a phenolic binder or an alternative binder with a low formaldehyde content, preferably even without formaldehyde, a binder sometimes referred to as a "green binder", particularly when it is at least partially derived from a base of renewable raw material, in particular plant-based, in particular of the type based on hydrogenated or non-hydrogenated sugars.
- the crosslinking system may also include one or more of the following characteristics, taken individually or in all technically possible combinations.
- the injection system comprises heating means, for example electric heating means, configured to heat ambient air to a given temperature.
- said given temperature is between 500°C and 2000°C, more particularly between 700°C and 1900°C, or even between 1000°C and 1900°C, even more particularly substantially equal to 1800°C. °C.
- the heating means comprise at least one electric battery whose power is between 100 kW and 900 kW, more particularly between 500 kW and 700 kW, for example substantially equal to 600 kW.
- the injection system is supplied with preheated air
- At least part of the preheated air comes from a glass melting furnace and/or corresponds to hot recovery air.
- the injection system is connected to an emergency evacuation of hot air positioned between said injection system and said reticulation oven.
- the injection system is configured to inject hot air coming from outside the crosslinking oven.
- the injection system comprises a hot air supply pipe arranged between a hot air source arranged outside the reticulation oven and the at least one combustion chamber .
- the invention relates to a line for manufacturing a continuous mattress of mineral and/or vegetable fibers, comprising a unit for fiberizing a continuous mattress of mineral and/or vegetable fibers, a conveyor for transporting the mattress as well as a crosslinking system according to the invention.
- the invention relates to a method for crosslinking a continuous mattress of mineral and/or plant fibers, said method being implemented by means of a crosslinking system according to the invention.
- the invention relates to a process for manufacturing a continuous mattress of mineral and/or plant fibers, said process being implemented by means of a manufacturing line according to the invention.
- the L_FAB manufacturing line comprises a fiber drawing unit 1 configured to implement an internal centrifugation fiber drawing process known per se.
- the fiberizing unit 1 includes a hood (not shown on the ) topped with at least one centrifuge 2.
- Each centrifuge 2 comprises a basket (not shown on the ) for the recovery of a previously melted fiberglass net and a plate-shaped part 3 whose peripheral wall is provided with a large number of orifices.
- the molten glass brought in a stream 4 from a melting furnace (not shown) and first recovered in the basket of the centrifuge 2, escapes through the orifices of the plate 3 in the form of a multitude of filaments driven in rotation.
- the centrifuge 2 is also surrounded by an annular burner 5 which creates at the periphery of the wall of the centrifuge 2 a gas stream at high speed and at a sufficiently high temperature to stretch the glass filaments into fibers in the form of a veil 6 .
- a binder sometimes referred to as a "green binder", particularly when it is at least partially derived from a base of renewable raw material, in particular plant-based, in particular of the type based on hydrogenated or non-hydrogenated sugars.
- Each box 21-25 comprises a central compartment 21_CC-25_CC forming an enclosure of said box and surrounded by an insulation material.
- hoods 19A and 19B arranged at the inlet and outlet of the SYS_R reticulation system only constitutes a variant implementation of the invention. Any other variant known to those skilled in the art can be considered, such as for example a variant according to which a hood is arranged substantially in the center of the crosslinking oven 14.
- Each burner is supplied with gas and combustion air from a gas pipe 26, so as to produce hot air intended for the heating box 21-25 connected to the combustion chamber 31-35 with which it cooperates said burner.
- This gas supply is symbolized on the using arrows F1.
- the setting temperature of a combustion chamber 31-35 is between 200°C and 250°C (or even up to 300°C), for example equal to 210°C, 215 °C, 225°C, etc.
- the crosslinking system SYS_R comprises, in addition to the crosslinking oven 14, a so-called “injection” system SYS_I arranged outside said oven 14.
- the SYS_I system can be positioned on the ground next to the enclosure of the oven 14, or even at height, for example on a dedicated walkway.
- the injection system SYS_I is configured to inject hot air into at least one combustion chamber 31-35 (and therefore a fortiori into at least one heating box 21-25), the hot air thus injected coming into replacement of a given fraction of hot air produced by the burner attached (cooperating) with said at least one combustion chamber 31-35, said fraction being between 20% and 100%, for example between 30% and 95%, more particularly between 40% and 80%.
- the hot air injected into a combustion chamber 31-35 by means of the SYS_I system replaces all or part of the hot air produced by the burners (i.e. the hot air circulating in a heating box 21- 25 and produced exclusively from gas used by the burners).
- the value of the fraction is fixed so as to replace (substitute), with the hot air injected with the injection system SYS_I, a given part of the energy/power supplied by the burner of said at least one combustion chamber 31-35.
- the hot air source is external to the oven.
- the hot air injected is distinct from the gases recirculated by the recirculation circuits of the combustion chambers 31-35.
- the injection system SYS_I is configured to inject hot air into the recirculation circuits of each of the combustion chambers 31-35, more particularly at the inlet of said combustion chambers 31-35. This injection of hot air is symbolized on the using arrows F2.
- the injection system SYS_I may include balancing valves 60 arranged between a hot air supply pipe 70 of the system SYS_I and said combustion chambers.
- Each balancing valve 60 can be controlled, so as to allow a supply of hot air to a particular combustion chamber 31-35, for example for a given period of time.
- the control of one or more balancing valves 60 can be carried out automatically (ie in a programmed manner).
- the inlet of the hot air supply pipe 70 is in fluid communication with an exterior of the oven 14.
- the hot air supply pipe 70 is configured to supply hot air coming from outside the oven 14.
- the electric heating means 80 can for example comprise at least one electric battery whose power is between 100 kW and 900 kW, more particularly between 500 kW and 700 kW, for example substantially equal to 600 kW, said at least one battery allowing to supply electricity, for example, to one or more electrical resistances (not shown in the figures) capable of heating the ambient air to the desired temperature.
- the number of electric batteries is equal to the number of heating boxes in the oven 14.
- the injection system SYS_I is also connected to an emergency evacuation 100 of hot air (also called “emergency chimney") positioned between said system SYS_I and said reticulation oven 14. More particularly, and as illustrated over there , the connection between the SYS_I system and the emergency evacuation 100 is made by means of an evacuation pipe 110 equipped with a balancing valve 120.
- an evacuation pipe 110 equipped with a balancing valve 120.
- Such a configuration is optional, and has the advantage, particularly (but not exclusively) when the SYS_I system is supplied with preheated air, to avoid any accumulation of heat damaging to the operation of the SYS_C reticulation system.
- the invention does not only relate to the SYS_C crosslinking system as well as the L_FAB manufacturing line. Indeed, the invention also targets a method of crosslinking the mattress 12 implemented by means of the SYS_C crosslinking system.
- Said crosslinking process comprises in particular steps of heating the mattress 12 within each of the heating boxes 21-25, it being understood that all or part of these heating steps (depending on whether all or part of the heating boxes 21-25 are connected to the SYS_I system) are carried out by supplying hot air from said SYS_I system.
