Description

WATER-CO0LED AND INTERMITTENCE THROWING TYPE INCINERRATOR}

The present invention relates to a water-cooled intermittent incinerator, and more specifically, the cooling system has a water-cooled structure, and the water-cooled air is supplied three-dimensionally in the combustion chamber to improve the combustion efficiency of the incinerator incinerated by injecting incinerators intermittently. It relates to an intermittent incinerator.

As the industrial society is advanced and the standard of living of the people is improved, industrial and household waste is increased to become a social problem, and it is difficult to establish narrow facilities such as waste incinerators due to local autonomy. Increasingly, various types of incinerators have recently been installed.

On the other hand, the general incinerator has a structure in which a plurality of orifices for introducing air are installed on the wall of the heat chamber, but such an incinerator is not supplied to the deep part of the incinerator because air is supplied only around the inner wall of the combustion chamber, The carbon body adheres to the inner wall of the combustion chamber during the incineration process, so that the combustion area and the combustion efficiency are lowered and the air outlet of the orifice is blocked, causing incomplete combustion.

Therefore, in recent years, the wall of the combustion chamber is doubled to form a cooling jacket filled with coolant therein, and an air supply pipe is formed in the inside of the cooling jacket, while an injection nozzle for injecting air is provided to the wall. A water-cooled intermittent incinerator constructed at right angles has been proposed.

However, the conventional water-cooled intermittent incinerator has been solved somewhat by the problem of carbon adhering to the inner wall of the combustion chamber. Therefore, air is supplied to the incinerator flatly, and incomplete combustion occurs due to the unsupply of air at the deep part of the incinerator and the bottom of the incinerator, which causes serious environmental pollution due to the increase of soot and harmful gases. The residence time of the incinerator is increased in the combustion chamber, and the incineration efficiency is reduced, and a separate worker for supplying air to the unburned incinerator by manual operation (the operation of changing the position of the incinerator as a separate tool such as a stick) during incineration. This increases management costs and risks of safety accidents such as burns at work. There is a problem in that material.

The present invention is to solve the above problems, the object of the combustion efficiency is that the air supplied in the combustion chamber of the incinerator is injected three-dimensionally from the bottom wall and the upper wall as well as the side wall and vortex generated in the air injected in the combustion chamber It is to provide a water-cooled intermittent incinerator to improve this.

In order to achieve the above object, the present invention is composed of a combustion chamber divided into a first combustion chamber in which the incineration is first burned and a second combustion chamber in which secondary combustion is carried out by a connection duct above the first combustion chamber. A cooling jacket is formed between the side wall formed by the inner plate and the outer plate so that the combustion chamber is formed, and the first air chamber is installed outside the incinerator body to store the compressed air applied from the fan, and the first air chamber is in communication with the first air chamber. A plurality of first supply pipes installed in communication with a second air chamber formed at the bottom of the incinerator main body and communicated with the second air chambers in the left and right side walls, a plurality of second supply pipes installed on the front and rear side walls; And a plurality of third supply pipes connected to the first supply pipe and the second supply pipe so as to be horizontally arranged inside the upper wall of the combustion chamber, and the injection nozzles are inclined on each supply pipe. In the water-cooled intermittent incinerator is provided with a cyclone for separating the solids in the exhaust gas discharged through the duct communicating with the combustion chamber, the installed air supply device, and a stack through which the exhaust gas passing through the cyclone is discharged. The nozzle has a spray nozzle installed on the bottom wall to be inclined into the first combustion chamber through the bottom wall to directly communicate with the second air chamber, and an air control valve is installed on the first air chamber to control the amount of air supplied into the second air chamber. Characterized in that the exhaust pipe is connected.

When the combustion occurs in the first combustion chamber 11a, the temperature of the water cooling jacket 50 is increased, so that the temperature of the air supplied into the combustion chamber through the supply pipe 60 installed in the water cooling jacket 50 is increased so that the combustion efficiency is increased. This improves and the phenomenon that the carbon body adheres to the inner wall of the combustion chamber 11a by combustion by the water cooling jacket 50 is reduced.
