Abstract

The present invention is a general-purpose combustible waste treatment system for drying combustible waste using indirect heat and producing alternative energy at the same time by inhibiting generation of harmful gases (dioxin, etc.) by gas decomposition using mineral catalysts in a low temperature and low oxygen environment. Conventional direct incineration causes pollution, and pyrolysis is uneconomical in terms of equipment and operation. The present invention sequentially heats the carbide drum and the dryer by using hot air of a high temperature furnace. Wastes passed through the dryer are introduced into a carbonized drum with an internal temperature of 400 ° C. at low oxygen (within 5%), reacted with a catalyst containing rare earth complex acid, and stirred, carbonized and discharged with a stirring device. The gas is sent to a series of reactors, second catalysts, and separation towers to separate the oil at its boiling point, and the bad gas is burned in a high temperature furnace during a series of circulation processes.

Description

Waste disposal system

The present invention is to dry the combustible waste using indirect heat and to decompose harmful gases (dioxin, etc.) by gas decomposition using mineral catalysts at low temperature and low oxygen environment, and at the same time to replace alternative energy (petrol, diesel, gas, carbon) The present invention relates to a general-purpose combustible waste plant system.

Conventionally, incineration of combustible wastes has been disposed of by direct combustion incineration, and recently pyrolysis has emerged.

However, the former causes a lot of pollution and wastes accumulate in the event of a failure of the equipment. The latter has a problem in that the cost of the equipment is excessive, the cost is insufficient, and the waste accumulates in case of equipment failure by decomposing it into heat and using gas as the gas itself.

An object of the present invention is to enable the production of alternative energy (petrol, diesel, gas, carbon) and carbon that can recycle all flammable waste, and to dispose of the waste without pollution without toxic gas emissions such as dioxins.

It is a waste disposal system with the characteristic of producing oil and removing oil.

In addition, the present invention is a high temperature furnace 22, a drying facility for drying the waste by indirect heat of the high temperature furnace 22, and a dry matter discharged through the automatic discharger (6) in this drying facility is introduced without external exposure, And carbonizing the dry matter introduced by the relatively low indirect heat of the high temperature furnace 22, and having a heat passage device 18 capable of efficient heat transfer between the outer cylinder 15 and the inner cylinder 16, inducing even carbonization of the contents. It is a waste treatment system consisting of a carbide drum (3) having a stirring device (11). An upper discharge space is formed in the upper portion of the carbide drum 3 to induce rapid discharge of the generated gas.

In addition, the present invention utilizes the heat of the high-temperature furnace 22 generated by using the bad gas of the gas generated in the carbonization process and the oxide carbonized in the carbide 3 as a fuel for heating and power generation, and the waste heat is used as a carbide, Waste treatment system characterized in that the heat supply to the drying equipment.

In addition, the present invention is the gas generated during the disposal of the combustible waste is transferred to a series of reactors, a second catalyst device, a separation column to separate the oil according to the boiling point, the defective gas is burned in a high temperature furnace during a series of circulation processes It is a waste treatment system that produces pollutants without pollution by gas fueling and purifying gaseous catalysts by incineration of its own fuel.

The system operating method of the present invention first generates a high temperature furnace 22 1300 ℃ high temperature with the diesel burner 19, the high heat is passed through the boiler thermal efficiency between the outer cylinder 15 and the inner cylinder 16 of the carbide 3 The inner cylinder 16 is heated while moving the lower portion of the apparatus 12-1 to raise the upper portion, and the inner cylinder 16 is heated to the upper portion and exits through the outlet 8.

The outer cylinder 15 and the inner cylinder 16 are divided into three parts to increase the efficiency of heat, and the inlet 7 and the outlet 8 are also divided into three parts. The inner surface of the drum 3 outer cylinder 15 was made of a refractory material 17 to prevent heat loss. Heat exiting between the outer cylinder 15 and the inner cylinder 16 of the carbide 3 is set at a temperature of 120 ° C. in the heat exchanger and introduced into the dryer barrel.

The waste dried in the drying furnace (not shown) is introduced into the carbonized drum 3 cylinder in which the internal temperature of the cylinder 3 is 400 ° C by indirect heat by the automatic input device 2. The injected waste is vaporized by the catalytic reaction 14 of the cylinder attached between the outer cylinder 15 and the inner cylinder 16, and gradually agitated by the stirring device 11, and automatically discharged by the spiral screw 12 ( Carbonized while moving to 6).

The stirring device 11 is attached to the stirring shaft 13 and the pushing spiral device 12 to stir and push the waste on the rotating shaft. In addition, the drum outer cylinder 15 is provided with power units 4a and 5b for rotating the stirring shaft 11, and the stirring shaft 11 inside the drum is divided into two equal parts in the longitudinal direction. The power of the power units 4a and 5b can be freely reversed and reversed in the opposite direction, so that the injected waste is quickly carbonized. The tip of the stirring blade was in the form of a spatula (7-1), and was attached to the blade tip and the tip of the blade (7-1) was configured so that the rotation speed of the stirring shaft 11 evenly stirred.

Gas generated in the waste carbonization process is carried out through a desulfurization, denitrification, and dechlorination reactor (not shown) installed in the outlet pipe through the discharge device 6 in the inside of the barrel 16 (not shown). ) Is reacted to the catalyst and transferred to a separation tower (not shown), and separated into volatile and light oils depending on the boiling point.

The defective gas which cannot be oilified is arranged to be transferred to the heat generating high temperature furnace 22 to explode in the furnace to become the energy of the present process.
