Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for recovering fuel oil and fuel gas from polymer compound waste such as scrap tires.

Incineration of polymer compounds such as waste tires generates toxic gases such as NOx, so such incineration treatment is currently difficult.

Therefore, in recent years, research and development has been conducted to recover useful substances by thermal decomposition as a treatment for these.

However, the conventional collection equipment is large and requires a considerable amount of equipment, making it impossible for general waste disposal companies to contract for it.

Therefore, the local government has installed it on one side and has it used.
Since it is necessary to transport it to the installation location, it causes a time and financial burden.

Therefore, the present invention aims to downsize the device and recover more useful substances, particularly fuel oil.

An embodiment of the apparatus of the present invention will be described based on the drawings. 1 is a decomposition tank, 2 is a cooling tank, 3 is a gas cleaning tank, and 4 is a decomposition tank.
is Gashordan.

The decomposition pot 1 is fitted into the heating furnace 11 and is fixed or detachable.

Reference numeral 1a denotes a sealing lid that is pivotally attached to the disassembly pot 1 so as to be openable and closable.

12 is a connecting pipe that connects the upper part of the disassembly kettle 1 and the lower part of the end plate 2a of the cooling unit 2.

The cooling tank 2 has a water jacket 21 on its outer peripheral surface, and the inside of the tank is divided into compartments by a blocking wall 22 provided with through holes 22a.

23 is a recovered oil faucet. 24 is a connecting pipe, which connects the upper part of the end plate 2b of the cooling tank 2 and the end plate 3a of the gas cleaning tank 3.
It is connected to the lower part of.

The gas cleaning tank 3 has a shielding wall 31 that holds water and has a through hole 31a.

A connecting pipe 32 connects the upper part of the gas cleaning tank 3 and the lower part of the gas holder 4.

Since the present invention has the above-described structure, when the lid 1a of the decomposition pot 1 is opened and a waste tire is loaded, the lid 1a is sealed and heated, the waste tire is thermally decomposed in the decomposition pot and gas is generated. do.

This pyrolysis gas passes through the connecting pipe 12 to the cooling tank 2.
flows into.

Since the cooling tank 2 is divided into compartments by the shielding wall 22, the gas does not leave the cooling tank 2 all at once, but instead flows turbulently in each compartment.Only the remaining gas flows into the gas cleaning tank after passing through the through holes 22a. It happens.

Therefore, the time during which the gas stops flowing in the cooling tank 2 becomes longer, the cooling efficiency can be increased, and the recovery rate of fuel oil can be increased.

Further, the residual gas that has flowed into the clean tank 3 may contain NOx, but when it comes into contact with the water in the clean tank, it is desulfurized and the gas is purified.

Therefore, the purified gas passes through the connecting pipe 32 and is stored in the gas holder 4.

In addition, if a water jacket 21 is provided on the outer peripheral surface of the cooling tank 2 and water is constantly allowed to flow therein, it is possible to prevent the temperature of the tank surface from rising, and the cooling efficiency can be further improved.

In this way, the present invention can recover purified fuel oil and fuel gas by thermal decomposition of waste tires and other polymeric wastes, which not only prevents pollution but also enables recycling. Since the device also has a blocking wall erected inside the cooling tank, it can be made smaller and can be installed in a small-scale waste treatment plant.
