Description

BACKGROUND OF THE INVENTION The invention relates to waste disposal equipment and is intended to recover tires, rubber and plastic waste.

A known pyrolysis apparatus for the disposal of rubber waste is described in SI <patent no. 50772007, published June 06, 2008, consists of a chimney furnace containing a pyrolysis chamber with an exhaust duct connected to a suction device. At least one electric heating element and a burner are provided in the space between the heating chamber and the pyrolysis chamber. A collection tank is provided for collecting the substances released during the pyrolysis process.

The disadvantage of the known pyrolysis apparatus is that the heating of the chamber is electric and uneconomic. In addition, the temperature of the pyrolysis process is not high enough to cause the concentration of combustion products to be exceeded in the environment.

The purpose of the invention is to provide environmentally safe, efficient and economical utilization of tires, rubber and plastic waste.

In order to achieve the object of the invention, the tire, rubber and plastic recovery unit comprises a solid fuel firebox, a gas chamber, a burner mounted between the gas chamber and a gas combustion chamber with an exhaust chimney, a metal vessel with a lid, integrated in a gas combustion chamber, waste condensate collector. - a dehumidifier having one end connected to a gas outlet pipe connected through a sleeve to a pipe in a metal vessel cap and the other end connected to a residual gas channel to the burner on the side of the gas collection chamber; in addition, the condensate collector-cooler is equipped with condensate drain valves.

Also, in order to achieve the object of the invention, the body of the gas combustion chamber is double, the internal part is fired brick, the outer part is metal. In addition, the body of the gas combustion chamber may be insulated with insulating material.

The invention is illustrated in the drawing. The drawing shows a tire, rubber and plastic recovery unit.

The tire, rubber and plastic waste disposal unit comprises a solid fuel furnace 1, a gas collection chamber 2, a burner 3, a gas incineration chamber 4 with an exhaust chimney 5 provided with a metal receptacle 6 with a lid 7 for containing waste, a gas outlet pipe 8 a condensate collector 9 on the side of the gas collection chamber 2 of the residual gas channel 10 to the burner 3. A pipe 11 is provided in the lid 7 of the metal vessel 6, connected to the gas outlet pipe 8 via a sleeve 12. The condensate drain valves 13 are provided in the condensate collector 9, between the gas combustion chamber 4 and the gas collection chamber 2. mixture at high temperature. The gas burner chamber 4 has a double body. Its inner part is made of fireclay brick and the outer part is metallic. The gas combustion chamber 4 may be insulated with insulating material.

During combustion of solid fuels such as firewood in the furnace 1, the flammable gas from the gas collection chamber 2 enters the burner 3. In the burner 3, the flammable gas mixes with the hot air supplied from the environment to the hot burner. Heat a metal container 6 containing tires, rubber or plastic to a temperature of C. In this way, the thermal treatment of waste - pyrolysis - takes place. The waste, when heated at high temperature, to a temperature of at least 1000 ° C in the lower part of the vessel 6, produces gaseous, liquid and solid materials. The gas from the metal vessel 6 passes through a conduit 7 in the cap 7, which is connected via a coupling to the gas outlet 8. The volatile gas is discharged through the gas outlet 8 and the residual gas suitable for use is routed back to the burner 3 . In the burner 3, they mix with the flammable gas entering the burner 3 from the gas collection chamber 2 and with hot air, again forming a flammable mixture. Liquid material - condensate (flammable liquid) - is discharged through condensate drain valves 13 from condensate collector-cooler 8. Solid carbon, which is accumulated in the lower part of the metal vessel 6, is removed by opening the lid 7. This carbon can be used in a wide variety of applications.

The claimed recovery facility operates efficiently and reliably. It ensures safe, environmentally friendly and economical disposal of tires, rubber and plastic waste. An important advantage of the claimed unit is that its design allows the use of residual gas to produce a flammable mixture while saving fuel costs. The reduction in fuel consumption is also particularly influenced by the fact that the declared recovery unit is equipped with a furnace and burner, which achieves a high combustion temperature of the combustible mixture. In addition, the pyrolysis of waste in the metal vessel does not produce, as in a normal combustion process, the presence of harmful substances and the concentration of combustion products discharged into the environment through the exhaust chimney is below acceptable limits. In addition, the double combustion chamber of the gas-fired chamber, the internal part of which is made of fireclay brick and the outer part of which is made of metal, allows to maintain a constant and high temperature necessary for pyrolysis.
