Definitions
- the present invention relates to a waste treatment process containing asbestos, from a site generating such waste, including a reaction by attack of said waste with a basic solution until a reaction product is obtained without asbestos fibers.
- WO-A-93/18867 describes a process in which the waste is first of all very finely ground in the presence of at least one substance releasing OH ions - in water, so as to form an aqueous suspension . This suspension is optionally then transferred to an autoclave and treated at elevated temperature and pressure.
- WO-A-94/08661 describes a method of treatment as indicated at the beginning. This process has only aim of producing waste that can be unloaded in a warehouse without the risks inherent in asbestos. The only installation described to realize this treatment is a fixed processing center, large dimension, which therefore provides no solution to waste transportation and storage issues containing asbestos. Finally, during treatment, waste undergoes energy-intensive compaction before their introduction into the treatment chamber.
- the object of the present invention is to provide a process and installation which avoid the disadvantages mentioned above and which allow processing of waste on the site generating such waste.
- site waste generator you have to hear not only a building in which we dismantle all the elements containing asbestos, but also for example a deposit rubbish where bags containing asbestos have been previously accumulated. It is therefore desirable that the installation is small and transportable.
- the invention further aims to avoid any risk of pollution between the generating site and the reactor that will process the waste, i.e. risks of waste bagging and transport of these sachets to a remote processing center.
- the bagging of construction debris is awkward and very often causes the piercing of sachets, which then allows the asbestos to spread in the atmosphere outside the site.
- the invention also aims to prevent the maximum any product release occurring in the processing, insofar as it still contains asbestos fibers. Treatment products will be advantageously either recycled or suitable for revaluation.
- the invention finally aims to avoid any crushing, crushing or compacting prior to entry in the reactor and therefore an introduction into it, without sorting, substrates loaded with asbestos.
- the transfer takes place in a container removable, closed, and the method further comprises, during or after the transfer, an external washing of the container with washing liquid.
- an external washing of the container with washing liquid This eliminates asbestos dust that may have settled on the container during its presence in the generating site of waste and therefore not to contaminate the place, near the site, where the basic attack will take place.
- the container wash water is recycled in the formation of basic attack solution which avoids any pollution of the environment at the exit of the container closed off the waste generating site.
- the removable container used for transfer aforementioned is also the reactor in which the attack reaction. There is therefore in this case no risk of asbestos pollution during transfer from one container to another, waste without sorters are directly introduced into the reactor at generator site itself.
- the attack reaction is carried out with the basic attack solution at a temperature of the order of 175 to 190 ° C and under a pressure of about 8 to 10 kg / cm 2 .
- the installation illustrated in FIGS. 1 to 3 comprises a reactor 1 in the form of an autoclave which can be sealed in a sealed manner by a cover, for example a flip-up cover.
- This reactor is designed to be able to withstand internal pressures of up to 10 kg / cm 2 . He. is here movable on a carriage 3 provided with rollers 4.
- This assembly is dimensioned so as to be able to enter buildings, and therefore to be able to pass through doors and enter an elevator. This makes it possible to fill the reactor 1 with waste dismantled in the building, containing asbestos fibers, without prior sorting or grinding. Once the reactor is filled at the waste generating site itself, and therefore without handling bags, the reactor is taken out of the building where the waste is dismantled.
- He is then preferably brought to a post 5 (figure 1) which has a watering ramp 6 upper, preferably supplied with water under pressure, and a cabin 7, the floor of which is arranged in 8 wash water harvesting basin, which is then charged with the dust that has accumulated on the reactor during its passage through the generator site waste, dust which probably contains themselves asbestos fibers.
- the collected wash water is sent to a collecting tank 9, via an outlet conduit 10, fitted with a pump 11.
- the tank 9 is, in the illustrated embodiment, itself mounted so that it can be moved on wheels.
- Reactor 1 was transferred from carriage 3 to a support 12 capable of tilting around a shaft 13.
- the output shaft of a rotary motor 15 is coupled to an installed agitator in a known manner at the bottom of the reactor.
- An engine, no shown, allows the shaft 13 to rotate on its axis and tilt the reactor. All these measures allow appropriate agitation of the contents of the reactor during the attack.
- Quick connect fittings allow connect reactor 1 to an upper duct 16 and to a lower duct 17, each closable by means of valve.
- the upper duct 16 is in communication with a multi-way valve 18.
- the valve 18 allows a entry of rinse water into the reactor from the conduit 19 and / or a basic attack solution inlet from line 20.
- Electric heating elements 21 are, in the illustrated embodiment, provided inside from reactor 1, and they are connected to a source current when the reactor is in place on the support 12.
- the attack with the aqueous basic solution can therefore take place in the reactor 1, without possible exit of asbestos fibers to the outside.
- the basic etching solution may for example be an aqueous solution of OH - ion generating agent, such as alkaline or alkaline-earth bases, in particular 25 M NaOH in flakes, obtained for example by dissolving in 0.5 part by volume of water of 1 part by volume of such NaOH flakes.
- the attack preferably takes place at a temperature of 175 to 190 ° C and under a pressure of 8 to 10 kg / cm 2 , for a period of 20 to 30 minutes, advantageously with slow stirring, optionally intermittently. After this attack, there is substantially no more asbestos fibers in the reaction product which is of pasty consistency.
- This reaction product is taken out of the reactor 1 by the lower pipe 17, after opening the corresponding valve, and it is brought to a running centrifuge 22. This transfer can be followed by an internal rinsing of the reactor by adding rinsing water. from
- fresh water or rinse can still be supplied by a conduit water inlet 23.
- the centrifuge separates in the pasty product a liquid phase and a precipitate solid.
- the liquid phase consisting mainly of water and attack base is recovered at the bottom of the centrifuge to be recycled through a recycling conduit 24.
- the solid precipitate is sent through the outlet 25 in a bin 26 from which a revaluation of this precipitate may take place.
- Reactor 1 when it closed on the generating site, contains in addition to the waste introduced air heavily loaded with dust and therefore asbestos fibers. During the attack, these particles in suspension are washed and attacked in the same way as solid waste, and asbestos fibers that were suspended are therefore also destroyed.
- the cover 2 of the reactor 1 can then be open without any danger of environmental pollution.
- Debris that has been introduced with the waste asbestos on the generating site for example bricks, pieces of wood, etc Vietnamese, can then be discharged by tilting the reactor, and possibly scraping the interior. This debris, completely free of asbestos fibers, can then be routed to a depot or other destination.
- the installation comprises a solution preparation tank 29, capable of withstanding a pressure of 10 kg / cm 2 and capable of being heated for example by a heating jacket 30 in which a thermal fluid circulates, including oil.
- the thermal fluid enters at 31 into the jacket 30 and exits at 32.
- Fresh or rinse water may be supplied in the tank 29 by the inlet duct 36.
- a outlet conduit 37 of the basic etching solution allows the latter to be taken from the bottom of the tank 29, using a pump 38.
- This outlet duct 37 is in communication with conduit 20 previously mentioned (see Figure 2) by a valve 39 which is open when reactor 1 must be supplied with basic solution of attack.
- valve 39 When valve 39 is closed, the solution basic attack is recycled at the top of the tank 29 by a bypass 40, using a static mixer 41. In this tank the basic solution is brought to the desired concentration, at a temperature close to boiling, for example 120 ° C.
- the installation also advantageously comprises an equalization tank 42 for the basic attack solution.
- This tank is preferably capable of withstanding a pressure of 5 kg / cm 2 , and it is capable of being slightly heated, for example by a heating jacket 43 in which a thermal fluid, in particular oil, circulates. The thermal fluid enters 44 in the jacket 43 and exits 45.
- Fresh or rinse water may be introduced into the tank 42 through the inlet conduit 48.
- An outlet conduit 49 of the basic equalization solution allows to take it from the bottom of the tank 42, using a pump 50.
- This outlet duct 49 is there is communication with a supply duct 51, by a valve 52.
- This supply duct 51 allows introduce at the top of the preparation tank 29 a basic equalization solution and thus get a basic attack solution of uniform composition.
- valve 52 is closed, the basic solution equalization is recycled to the top of the tank 42 by a bypass 53, using a static mixer 54.
- FIG 4 there is shown the arrangement on a platform 56, transportable by trailer, training part of the basic attack solution the installation.
- the tanks 29 and 42 of Figure 3 are supported on tray 56. Next to these tanks is a current thermal fluid heating device with a thermal fluid tank 57 and a boiler 58.
- a battery is shown of reactors 1 supported on a transportable tray 64 by trailer.
- the reactors are introduced into a heated enclosure 59, the upper part of which can be opened for insertion or the extraction of reactor 1.
- This operation is carried out using a lifting device known per se 60.
- the heated enclosure 59 is supported on two ends of the shaft 65 and 66 coaxial so as to be able to rotate around their axis.
- An agitation of 40 at 50 rpm is for example favorable.
- the left reactor in Figure 5 is supplied by a removable container in the form of a tray 61, whose upper wall 62 can be opened for the introduction of waste on the generating site.
- the bottom of this tank 61 provided for transportable and displaceable between the generating site and the transportable unit of treatment according to the invention, is formed by a hopper 63 closable by a drawer, not shown.
- the upper opening of the reactor is then closed by a corresponding drawer cover. When the two drawers are open, waste from bin 61 can flow into reactor 1, so as not to be able to come into contact with the surrounding environment.
- the two plates 56 and 64 can be installed side by side and to allow communication between the different containers by the conduits cited above.
- FIG. 6 a variant of improved installation of the following installation the invention, where the reactor 1 formed from an autoclave at high pressure of the installation according to Figures 1 at 3 is replaced by two successive reactors: 1) a removable reactor 1 'for example in the form a small autoclave capable of operating under extremely moderate pressure and 2 °) a 1 '' fixed reactor.
- Autoclaves corresponding to requirements of the removable reactor 1 ' are those used commonly in chemistry labs, and they're readily available on the market at moderate cost. These autoclaves have the added benefit of can be expected to be much lighter and less pressure resistant, due to low pressure Implementation.
- Waste containing asbestos is introduced into reactor 1 'as in reactor 1 of Figure 1 and it is advantageously washed with the same way when leaving the generator site waste. It is then connected to an upper conduit 16 ' which allows to put it in communication with the tank of preparation 29 of the basic attack solution.
- treatment of waste in reactor 1 'with the basic solution attack at a temperature of 160 to 175 ° C, advantageously at 170 ° C for 15 minutes.
- reaction product is then transferred by a conduit 17 'to a first centrifuge 22' where the liquid phase is separated from the solid phase.
- sentence liquid is recycled through line 24 'to the tank preparation 29 or to the equalization tank 42.
- the solid phase is in the form a paste which still contains asbestos fibers, totally separated. After analysis, we have already been able estimate that, in this state, the fibers obtained do not already pose more danger to human health.
- This solid phase now has a reduced volume 70% compared to that introduced into the reactor 1 '. It is brought, via a pipe 25 ', to the reactor 1' '.
- This is a fixed reactor, that is to say which no longer has need to be moved to the waste generating site, and yet it is of a small volume.
- it is arranged horizontally in order to be able to rotate around an axis horizontal.
- the basic etching solution is introduced through the 16 '' conduit and a temperature above 180 ° C, for example from 190 to 210 ° C, advantageously around 200 ° C, is maintained in the 1 '' reactor by a 21 '' heat source. There is then decomposition and total disappearance of the asbestos fibers, and formation of a pressure inside the reactor. However, since the treated volume of solid phase is reduced, a pressure of 2.5 kg to 10 kg / cm 2 , preferably 2.5 to 5 kg / cm 2 , may suffice.
- the reaction product is then transferred in a second centrifuge 22 '' through the conduit 17 '', passing through a cooling device 70.
- the temperature of the product from the 1 '' reactor is dropped below the temperature at which the soda vaporizes, i.e. around 180 ° C.
- this centrifuge there is phase separation liquid and solid phase.
- the liquid phase is recycled through the 24 '' pipe to the preparation tanks and / or equalization of the basic attack solution and the solid phase is brought through the 25 '' conduit to the tray 26.
- the 16 'and 16' 'conduits can, like the conduit 16 in FIG. 2, serve as recycling means gaseous medium from the respective reactor to the source of basic attack solution.
