Description
1 DEVICE FOR HOUSEHOLD REFUSE TREATMENT The present invention relates to the fabrication of an adsorber, plant necessary for application of patent No. 97005007 belonging to the company DCM. 5 The technical portion of the invention is to improve, on an industrial scale, plant including a "moving bed", a technique known in particular for collecting household refuse, but on the other hand on the basis of this concept to recover energy released by the chemical reaction when the plant concerned is operating, by heat exchange with longitudinal walls. 10 Moreover, consecutively to the concept of the method, it will be provided with an incoming product distributor. Finally, the plant will include a safety installation to alleviate any failure resulting from thermal runaway of the method caused by the action of materials being treated by a reaction that does not conform to the class of material to be 15 treated and unknown to us. The operating principle consists in engaging in the sheet steel adsorber obtained a useful volume corresponding to the hourly flowrate of products to be treated in accordance with the plan described hereinafter (fig. 1 and fig. 2) a product previously mixed with chemical reagents of compounds of elements 20 containing carbon, elements containing cellulose, material liable to decay, slurry, droppings, peat, greases and sludges from purification stations in the receptacle (2, fig. 1), which mixture is spread over the first third of the surface of the plant by distributor and evacuation screws (3, fig. 1). The moving bottom driven by a frequency variation electric motor and a transmission system move the product 25 forward toward the part opposite the inlet (E, fig. 1). It is further engaged by a set of screws (3, fig. 1) to respond to the input flowrate. The rate of advance of the product toward the point (E, fig. 1) is effected at very low speed (from 10 mm/min to 40 mm/min). During the time in which this mass transfer is effected, the mixture 30 introduced gives off energy whose temperature reaches 250 0 C with a low oxygen content. Because of the effect of this chemical reaction the product is hydrated to yield CaO + H 2 0 ... Ca (OH) 2 , by the other reagents induced in the product there is obtained capture of carbonic emissions: 35 CO 2 + H 2 0 ... H*, HCO- 3 + Ca(OH) 2 ... CaCO 3 + H 2 0 2 But also captures products resulting from the decomposition of the organic materials such as: CaCl 2 + RNH 3 As well as the malodorous gases by forming: CaSO 4 , 2H 2 0, the neutralization of the bases Ca(OH) 2 + Mci, the neutralization of the acids and 5 anhydrides such as: H 2 0 + CaA 2 . The gases resulting from the transformation of this mixture are evacuated through the pipework provided for this purpose (C, fig. 1) and directed towards a washer/dust remover. After remaining for approximately four hours in the adsorber, the product is 10 entrained by a set of screws to eject it (E, fig. 1), which set of screws is driven by a variable frequency electric motor. Given the temperature given off at the longitudinal sides of the adsorber, a double wall is provided (6, fig. 1) and (6, fig. 2), in which circulates through circuit delay means water containing glycol or any other usual thermal fluid, which enters at 15 A, fig. 2, and leaves at B, fig. 2. Temperature sensors are disposed at A, fig. 2 and B, fig. 2. In the top part of the adsorber there is a manifold (5, fig. 1 and fig. 2) on each side for injecting a neutral gas if the temperature increases excessively and also to prevent all risk of fire. 20 This invention can be applied to the following treatment processes: - fabrication of organic fertilizer - fabrication of compost. However, the latter must be used only in the context of the patent No. 9705007, because it is the basic application thereof. 25 Said adsorber includes at least one parallelepiped-shaped steel assembly (9. fig. 1 and fig. 2), a receiving hopper (2, fig. 1), a moving bed (1, fig. 1 and fig. 2), a set of screws (3, fig. 1) driven in rotation by any external means (8, fig. 2), which ensures the rapid transfer of the product entering at (D, fig. 1), a set of screws (4, fig. 1) driven in rotation by any external means (8, fig. 2), which ensures the 30 formation of crusting of the product and the extraction thereof by a rotation movement of the screws at low speed. The adsorber has on its longitudinal lateral . walls a double steel body (6, fig. 2) provided with a heat-exchange liquid inlet pipe (A, fig. 1) and a heat-exchange product outlet pipe (B, fig. 1) for recovering heat energy released by the exothermic reaction. The pipes (A and B, fig. 1) are provided 35 with temperature sensors. The body of the adsorber (9, fig. 1) is provided with an 3 opening with a double safety airlock and window (10, fig. 1) for installing an infrared video camera to monitor the reaction continuously to use the neutral gas distribution manifolds (5, fig. 1 and fig. 2) if necessary. Similarly, the body (9. fig. 1) of the adsorber has on its upper face an airlock for taking samples (11, fig. 1) for verifying 5 the behavior of the reaction and readjusting the proportion of the reagents and/or the total reaction of the elements and obtaining the expected result.
