Abstract

<P>PROBLEM TO BE SOLVED: To decompose and reutilize waste rubbers, waste plastics or the like, which has been hard to decompose heretofore, causing troubles recently into substances not exerting bad influences to the environments. <P>SOLUTION: The waste rubbers, waste plastics or the like are put in through a crushing machine part of the apparatus and are safely decomposed, gasified and separated by heat rays and α-rays, generated by heating heat storage stones or mica, and by catalytic reactions in the decomposition chamber, and a plurality of pure substances are obtained using a water-cooled condenser, water-cooled direct expansion freezing, a chiller or the like. As harmful substances are treated in a radiant tube helically coated with Ca (calcium) while intermittent discharge is carried out using a carbon electrode, tungsten or the like in the inner flame of the flame from the burner head, the apparatus is almost harmless and friendly to the environments. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention is intended to decompose, carbonize, gasify, and recycle waste rubbers, waste plastics, petroleum intermediates and the like.

  Conventionally, it has been considered difficult to completely decompose waste rubber, waste plastic, or an intermediate substance thereof.

  This time, it was found that waste rubber, waste plastic or its intermediate substances can be decomposed by α-waves and catalyst generated by applying heat to mica to generate a specific α-ray.

Means to solve the problem

  The structure of the treatment modification / reuse device for waste rubber, waste plastic or intermediate materials thereof will be described.

  Insert waste rubber, waste plastic or its intermediate material from the insertion slot.

  As for small things as they are, as for big things, waste rubber, waste plastic or its intermediate substance etc. are crushed finely by the crusher 1 and put in.

  The radiant tube 3 heated by the burner or the electric heater 27 gives specific heat energy to the mica or mica stone 2 to generate α rays from the mica or mica stone 2. At this time, the heat storage stone also emits heat rays.

  Waste rubber, waste plastics and intermediates are decomposed by the α-ray, heat, and the atmosphere adjusting gas and heat medium discharged from the atmosphere adjusting valve 12 set in the decomposition chamber.

  Since the mica and mica stone 2 or the equivalent is set around the radiant tube 3 during this thermal reaction, the contact effective area can be greatly increased and the heat radiation angle changes in various directions. Since the radiation angle is the same, the decomposition reaction efficiency can be increased.

  A method for removing the residue mixed in the waste rubber, waste plastic, or an intermediate substance thereof is to blow the gas by the blow pipe 4 in the decomposition chamber as shown in FIG. During discharge, residues, carbides, ash, sludge, etc. are removed from the reaction chamber so as not to circulate through the dust collector 6. In some cases, a secondary filter is attached but removed.

  However, if it is performed at a low temperature, it is controlled so that it is performed after baking. This operation was performed below the ignition point, but it was possible even at high temperatures using an inert gas atmosphere.

  There is no problem even if infiltration of sand, mud, various metal pieces, moisture, and the like is present in the processed object as shown in FIG.

  At this time, since the decomposed gas becomes hot, the apparatus is cooled by the cooling jacket 14, and the water heated to the high temperature by the cooling jacket 14 is converted into water vapor, led to the condenser, condensed, and passes through the boiler steam tank 18 and passes through the turbine 17.

  An electromotive force is generated from the turbine 17 by the generator 16 and used as electric power for the motor 25 control panel or the like.

  The steam that has entered the turbine 17 passes through the heat exchanger 10, is cooled by a refrigerator 11 (which may be a chiller), becomes water, and is sent to a water cooling jacket 14 for circulation.

  Heat storage stones heated by the radiant tube 3, mica stone 2 generate heat rays from the heat storage stone, and mica stones generate α rays, and the α rays and heat decompose the waste rubber, waste plastic and its intermediate substances into gas, It is divided into light oil, naphtha (fuel), heavy oil (A heavy oil / B heavy oil / C heavy oil) acid, salt, carbide, etc. through a fault passing through the insulator 7 and having a temperature difference by the water-cooled condenser 13.

  Further, the remaining gas at this time is burned by the blower burner 28 and becomes heat.

  The heavy oil that can be consumed here can be returned to the fuel tank and used as fuel.

The invention's effect

  This device generates electric power by the generator 16 and operates while using the converter 23 and the motor 25 control unit etc., so that power consumption can be suppressed and almost all HC (hydrocarbon constituent) is oiled. Can be

  Although various substances can be collected from the layer of the water-cooled condenser, the gas generated at this time is burned by the burner 28 and used, but the gas exhausted from the exhaust boiler 24 spirals Ca (calcium) into the radiant tube 3. It is harmless because it is coated and treated even if harmful substances are generated by pulse discharge with a carbon electrode.

  Moreover, since it is not burned, no harmful substances such as dioxin and CO2 are emitted.
