Description

incinerator

The present invention relates to an incinerator for incineration of wastes, and more particularly, to an incinerator for improving the incineration efficiency by forming a second combustion chamber to achieve complete combustion.

In general, incinerators are used to conveniently and cleanly treat wastes such as waste at industrial wastes or production sites, and are used to operate boilers using waste heat generated by them. Such a normal incinerator is provided with a combustion chamber capable of injecting waste and incineration, and a cyclone device for forcibly circulating air for smooth incineration of the waste. The air circulation during the cron operation is smooth but rather blows unburned gas particles into the exhaust gas passage. Therefore, in particular, thermoplastics such as plastics and synthetic resins are incinerated in the solid-liquid-gas phase. However, the conventional incinerator structure has a short combustion residence time in the combustion chamber, so that it cannot be completely burned. As the temperature is lowered, it accumulates in the exhaust gas passage again as a liquid. Therefore, the incinerator must be shut down to remove the unburned gas particles, resulting in a lot of time and labor loss, and unburned gas particles are discharged into the atmosphere through the outlet, causing secondary pollution. Increasingly, waste heat is not properly transmitted to the waste heat recovery boiler, so the efficiency of the boiler is significantly reduced, and the boiler operation rate is low as 60 to 70%.

For example, as shown in FIG. 1, the structure of a direct incinerator, as shown in FIG. 1, includes an inlet 1 for injecting waste, a cylinder 2 for injecting the waste into the combustion chamber 5, and to facilitate smooth combustion. An air nozzle (4) for supplying air into the combustion chamber (5), a pushing device (3) for inverting or pushing the center of the combustion chamber (5) for even combustion of the waste, and an outlet for discharging the incinerated ash (6) and in-line communication (8) to incinerate the incineration state and waste heat to the boiler, and the waste to be incinerated is combusted in the combustion chamber (5) in the solid and liquid state, and gaseous unburned gas particles They are combusted until they exit the straight line communication (8) until the combustion chamber (5) has a narrow and short structure, so that the unburned gas particles in the gaseous state cannot be completely burned together with the heat generated through the straight line communication (8).And songyeol the boiler waste gas it is released to the atmosphere. In other words, since the combustion is performed in a straight line in the straight incinerator, there is a lot of heat loss and heavy and light unburned gas is layered and moved to the waste heat recovery boiler. Trigo unburned gas is also emitted to the atmosphere through communication, increasing the environmental pollution.

Therefore, the present invention has been devised in view of the above problems, and the purpose is to improve the combustion chamber structure of the incinerator to lengthen the combustion residence time to achieve complete combustion, so that more than 90% of the waste heat is transmitted to the boiler without loss and unburned gas. It is to provide an incinerator that minimizes particles to be discharged to the atmosphere to prevent environmental pollution.

In order to achieve the above object, the present invention provides an inlet for incineration of waste, an air nozzle for supplying air to assist combustion, and a first combustion chamber and an incompletely burned gas for burning solid and liquid gaseous waste. The combustion chamber is composed of a second combustion chamber having a 'c' shaped vortex which is completely combusted, a horizontal wall which is horizontally installed at the upper end of the lower wall of the second combustion chamber, a horizontal wall and an upper side wall that surrounds the upper ceiling, and waste. It consists of a pushing device pushed into the chamber, a discharge port for discharging the incinerated ash, a see-through port for viewing the incineration state, and a communication for transmitting waste heat to the boiler.

The incinerator of the present invention constructed as described above will be described in detail with reference to the accompanying drawings.

2 is a view showing an internal structure in which the combustion chamber of the incinerator of the present invention is improved.

First, the inner wall is formed of a heat-resistant wall, a heat insulating wall, a heat-insulating silica board, and the outer wall is an incinerator 30 made of iron plate to form an inlet 21 of a fallopian tube on one side of the left and right sides, and the lower part of the inlet 21 A first combustion chamber having a cylinder 22 for pushing the waste into the combustion chamber at the incineration position, and having a pushing device 23 for inverting and pushing the waste for even incineration of the waste to the lower side of the inlet 21; An air nozzle 24 for supplying oxygen into the combustion chamber is formed at one side of the first combustion chamber 25 and discharged completely incinerated at one side of the first combustion chamber 25. The outlet 26 is formed, the first combustion chamber 25 is formed on the lower side of the outlet 26 for releasing the completely incinerated ash, one side of the first combustion chamber 25, the veneer for supplying thermal power (27) is installed. Then, the lower ceiling 25a is installed at the upper end of the first combustion chamber 25, the arch ceiling 25c is formed at the upper side of the lower wall 25b, and the upper side wall 29a and the upper ceiling 29b are formed around the lower ceiling 25b. To form a second combustion chamber 29 having a U-shape. One side of the second combustion chamber 29 is provided with a communication 28 for transmitting heat to the waste heat recovery boiler.

It will be described the operation relationship of the present invention made of the above configuration. The incinerator 30 ignited through the burner 27 feeds waste through the inlet 21 and is pushed completely into the first combustion chamber 25 into the cylinder 22. The waste is then combusted with the oxygen supplied through the air nozzle 24 (at this time the heating temperature is normally maintained at 800-900 ° C.). Combustion occurs, but the lower waste is not combusted, so the waste is inverted and pushed to the center using the pushing device 23, so that the solid waste and the liquid waste are evenly burned in the first combustion chamber 25. The gaseous unburned gas particles are formed of a jade ceiling 25c formed on an upper side of the lower wall 25b of the first combustion chamber 25, an upper side wall 29a formed along the periphery, and an upper ceiling ( It is completely burned through the second combustion chamber 29 composed of 29b). At this time, the vortex action occurs while passing through the rotating arrow, and the hot gas and the light gas are mixed and rectified, and the temperature is continuously maintained. The air is sent to the waste heat recovery boiler and the unburned gas is completely burned, thereby minimizing air pollution. The incinerator of the above configuration is easy to use in a narrow or narrow space production site or waste disposal site, has the advantage of maximizing the efficiency of the waste heat recovery boiler as well as complete combustion. Incidentally, the incinerator of the present invention is not limited to this, but may also constitute a plurality of layers of the structure of the second combustion chamber.

Therefore, the present invention facilitates the waste disposal work in a narrow space and constitutes a second combustion chamber in the 'c' shape, which extends the combustion space to achieve complete combustion and also generates vortex action in the bending section. The high temperature heavy gas and light gas rectify to maintain the temperature continuously to maximize the efficiency of the waste heat recovery boiler, and the exhaust gas is also completely burned to minimize the unburned gas particles and discharge into the atmosphere. In addition, the incinerator is shut down to remove unburned gas particles, thereby preventing time and manpower loss.
