- the cumulation of C0 2 recovered allows exploitation in various ancillary processes.
- the removal of its atmospheric equivalent in greenhouse gases, in each use and each use, is a huge gain for the ecosystem.
- Dioxide carbon C0 2 is produced once and used several times in processes that would have produced it in another way.
- the oxidizer used is preferably industrial oxygen, especially if the system is to be used in a complex with co-generation of energy. The thermal ratio is then much higher.
- the oxidizer can also be air
- the energy recovered in the exchanger 21 makes it possible to heat the C0 2 intended to be used for the treatment of wood, it is also used to produce steam at high pressure for the cogeneration of electricity 26.
- This electricity is used for the stabilization process according to the invention, which makes it autonomous. If the stabilization process according to the invention is used to also carry out the co-combustion of waste, the energy produced is greater than the needs of the system. The excess of cogenerated energies can be marketed and used in annexes to the complex.
- the wood treatment oven 10 is for example produced, with reference to FIGS.
- the two ends 11, 12 are removable to allow the transfer of the materials treated by the two ends.
- This feature makes it possible, with reference to FIG. 3, to assemble several oven modules 10.1, 10.2, 10.3, 10.4 to produce processing units of personalized length.
- the fixed vertical partitions 16.1, 16.2 of the module 10 are double-walled to provide a space in which the treatment gas GT and the charged gas GC extracted after treatment are conveyed.
- the outer wall is preferably insulated to control heat loss.
- the ends 11, 12 are mobile and removable, and they close the treatment volume VT when the load of wood B has entered.
- intermediate movable partitions can be installed to allow two separate treatment zones ZS, ZT, for example: drying on one side, high temperature stabilization on the other.
- a single generator 2 with its specific peripherals will supply the treatment gas GT t the energies useful to the system.
- the ceiling 13 of the oven module 10; 10.1, 10.2, 10.3, 10.4 is also double-walled 130, 131 between which is organized the gas distribution system SD; SD1, SD2, SD3, SD4.
- This distribution system is designed to receive the hot gas GT from the heat generator 2 and extract this charged gas GC after it has passed through the technical treatment volume VT.
- the lower / inner wall which concerns the technical volume of treatment, is movable so as to be adjusted to a suitable height, to compensate for variable heights of the load of wood B to be stabilized.
- the floor of the oven module 10 is equipped with rails 15A, 15B, with reference to FIGS. 2A and 2B, for the rolling of the carriage 14, carrying the load of wood B to be stabilized.
- deflectors 140 are fitted on the carriage 14 on either side to erase the technical rolling height.
- the extracted gas GC is returned to the reactor 23 of the thermal generator 2 to be purified before its reuse. This extracted gas is then charged with gasified elements when the temperature of the wood to be treated increases.
- the C0 2 gas used for treating the wood is thus continuously recycled. It is recovered at the outlet of generator 2 with the C0 2 produced by the combustions in the reactor (combustion of solid fuel and wood elements which have been gasified during treatment).
- the gas extracted after treatment of the wood is composed of the C0 2 introduced, water vapor coming from the wood, and combustible volatile molecules, gasified during the rise in temperature of the load of wood.
- the fuel gas parts will be reduced to the native elements in the thermal reactor, where all their available energy will be realized.
- the water vapor is purified by passing through the solid fuel reactor 23, it will be condensed into pure water after recovery of the thermal energy.
- the thermal energy recovered makes it possible to produce a quality of water vapor which will be used for the cogeneration of electricity 26.
- the residual heat, after cogeneration, is used for the stabilization process. Since the treatment gas is continuously recycled, this residual heat is recovered. There is an overflow of heat as and when recycling, this heat can be exploited in the annexes of a complex, for example: to dehydrate sludge from treatment plants in a closed process where C0 2 a also an active and neutralizing role, to supply electricity and heat to an industry, a community ...
- the treatment volume VT of the oven module 10 is kept under vacuum by an extraction fan 50 independent of the oven.
- the pipe 5 It is located outside on the pipe 5 for extracting the gases from the oven module 10 and for discharging towards the heat generator 2. It is this extraction of the charged gases GC which creates the vacuum in the treatment volume VT of the oven module 10.
- the charged gas GC is discharged to the reactor 23 of the generator 2 which purifies this gas in a permanent recycling.
- the C0 2 is recovered at the output of generator 2 by the methods described above.
- the CO 2 recovered is in the liquid phase, its temperature is between -85 and -100 ° C.
- the change of gas / liquid phase requires a significant amount of energy. This same amount of energy is restored during the change of liquid / gaseous phase, it is during this change of phase that the condensation of the water vapor contained in the extracted gas takes place.
- the C0 2 which must be introduced for the treatment captures its appropriate heat in the heat exchanger 21 as a function of the temperature programmed by the treatment cycle.
- the C0 2 is thus tempered and suitable for a new treatment cycle, it is sucked in by the vacuum created in the technical volume VT of the oven module 10, via the gas distribution system SD and so on.
- a system for compensating for pressure drops, linked to a large distance between the generator 2 and the oven module 10, can be installed on the line 4 of treatment gas GT.
- the thermal generator 2, the oven module 1 and the gas pipes 4, 5, connecting these two units, are thermally insulated, effectively to reduce energy losses and secure the surroundings.
- the continuous production of C0 2 accumulates with recycled C0 2 , which induces an overabundance of this gas.
- C0 2 is a strategic gas in the emerging economy, by its properties as a neutral gas for the conservation of certain foodstuffs in the food industry, as a substitute gas for prohibited refrigerant gases, as a raw material in technological materials.
- the gas distribution system SD located in the double wall of the ceiling 13 of the oven module 10, is designed to alternate the extraction of the charged gases GC , sometimes by the left wall 16.1 and sometimes by the right wall 16.2. Consequently, this ensures the alternation of entry of the hot treatment gases GT through the opposite wall.
- the effects of the hot treatment gas GT on the mass of wood B to be stabilized are thus distributed uniformly, the temperature of this mass thus rising very homogeneous.
- a four-way mechanism 6 is positioned at the junction of the connections: of the pipe 4 bringing the hot gas GT for stabilization, of the pipe 5 extracting the charged gas GC and, - of the pipes 62.1, 62.2 communicating with the fixed vertical walls 16.1, 16.2 of the oven module 10.
- This mechanism 6 is automatically controlled by the electronic program for conducting the treatment. It transfers and alternates the flows / extraction from one to the other of the vertical walls 16.1, 16.2.
- This four-way mechanism 6 is produced for example in the form of a parallelepiped whose four vertical faces are connected opposite: to the right and left walls 16.2, 16.1 of the oven module 10, at the gas inlet 4 GT treatment heat from the heat generator 2, as well as the extraction pipe 5 of the charged gases GC which are discharged to the heat generator 2.
- This mechanism 4 has a movable wall 60, centered on its vertical axis 61, which obscures the diagonals of the parallelepiped by pivoting on axis 61. This action alternates incoming and outgoing gas communications to the right-hand walls 16.2 or left-hand 16.1.
- vertical vents 52.1, 52.2 are arranged so that the transfers of gases, flow / extraction, can take place in the treatment volume VT.
- These louvers are fitted with mobile deflectors, which can be mechanized to distribute the treatment flow well.
- An upper part of these deflectors is made up of elements which can be closed independently, to allow the height of the ceiling to be adjusted in the VT treatment volume.
- the treatment gas flow GT is adjusted by varying the vacuum in the treatment volume VT of the oven module 10 by the power variation of the extraction motor 50. The purpose of this heat transfer mode is to make the 'aerodynamics of gases more fluid and thus avoid overheating of zones.
- the constant vacuum guarantees the impossibility of gas concentration inside the oven module.
- Means for injecting water vapor into the treatment gas flow are arranged to control the drying of the wood under the best technical conditions. In fact, drying too quickly would result in physical damage to the treated wood.
- the deflectors of the fixed vertical walls can completely block the louvers, this makes it possible to provide neutral zones when the load of wood to be treated does not occupy all the technical space of the oven module. In this case, a removable and adjustable partition separates the neutral zone from the active one to save the energy used and reduce the cost of treatment.
- the oven module 10 can also be arranged so that the movable end walls can also be moved in horizontal translation so as to be placed in close proximity to the ends of the load of wood B.
- the energy which is produced by the heat generator 2, to be transferred to the treatment gas C0 2 (which transfers part of it to the wood to be treated) is largely recovered by the generator 2, since the treatment gas GT is recycled continuously, so the energy it carries is also.
- the gas used for cooling the load of wood B, before taking it out of the oven module 10, is also recycled in the generator 2. There is therefore a large amount of energy available during and at the end of the cycle treatment.
- This energy can be used in ancillary processes, in particular for drying wood, energy which can be used in the stabilization process.
- the operation of the system can be made sustainable and more profitable by using certain wastes as co-fuels with [Bio-D] ®, for example,
- PUNR Used Non-Reusable Tires
- polluted wood which benefit from a disposal tax which comes to the benefit of exploitation.
- This exploitation of the system makes it possible to integrate it into a synergistic whole where: - the initial energy and the thermal base is plant biomass, therefore a renewable energy source, additional energy is supplied by combustible waste or wastes whose production required an energy supply.
- the "co-combustible" waste therefore contains a residual of the manufacturing energy which is entirely restored in the process.
- This is therefore also a renewable energy source, the cumulative energy produced can be used in ancillary systems having their own profitability and which will buy this clean energy.
