Abstract

PURPOSE:To prevent the leakage of a gas from the gas generator by partitioning the inside of a feed-in path by a plurality of switching doors and connecting either chamber of the feed-in path and a chimney by a pipe with a blower for suction. CONSTITUTION:When the waste tire 80 is pushed into a charging port 21, it drops along the inclined plane of the feed-in path 20 and is fed to the automatic switching door 30 while alternately opening or closing doors 22, 23, 24, and the automatic switching door 30 is opened by its own weight of the tire. When the waste tire falls into the generator 1, the gas in the gas generator flows out in a chamber 28 from a falling port 4, and intrudes in a chamber 27 when next waste tire is charged. However, some quantity of the gas flowing out of the gas generator 1 is discharged into atmospheric air from the chimney because the chamber 27 and the chimney are connected by the pipe 25 and the blower 39 for suction is installed to the pipe 25.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an exhaust gas generator using exhaust tires as raw materials.

In today's highly automobile-driven society, various problems have arisen regarding the disposal of old tires. In other words, tires are petroleum products and contain a large amount of carbon and tar), so when they are incinerated, they release black smoke and tar, which can become a source of pollution such as exhaust and bad odors. Ta. Therefore, when the tire loading door was opened to replenish tires during the evening incineration, black smoke and foul odors were emitted into the atmosphere).
Alternatively, there was a risk that outside air would flow back into the generator, rapidly increasing the pressure inside the generator and causing an explosion.

In view of these conventional drawbacks, the present invention provides a plurality of opening/closing doors in the passage for introducing tires, thereby preventing air from flowing back into the generating furnace and removing reducing gas containing black smoke, etc. inside the boiler.
