Description

High temperature combustion burner for incinerator

The present invention relates to a high-temperature combustion burner for incinerators, and more particularly, is installed in communication with an incinerator for incineration of waste tires and waste synthetic resins, so that the incomplete gas generated in the incinerator stays and retards in the burner as high temperature heat. It is configured to burn completely.

In general, the amount of waste tires is increasing as the demand for automobiles increases due to industrial development and the improvement of people's living standard. Such waste tires are treated by incineration, landfilling, and recycling. Among them, recycling of waste tires is preferred as the most efficient method in terms of environment, but recycling of waste tires is extremely limited. On the contrary, incineration and landfill of waste tires have the advantage of easy processing and low cost.

However, it is pointed out that the landfill of waste tires requires a wide landfill, and soil and groundwater are contaminated with pollutants generated from waste tires after landfill. Another method, incineration of waste tires, involves the consumption of fuel, and there is a great concern for air pollution due to dust and waste gases including harmful substances generated during incineration.

Even with these problems, it is difficult to secure sufficient landfill in a narrow land area. Currently, Korea is heavily dependent on the incineration of waste tires. As described above, an energy efficient boiler apparatus has been proposed to reuse heated water as hot water or heating water by heating water using hot combustion gas generated by reburning waste gas generated by incineration of waste tires. to be.

However, boiler devices connected to such incinerators cannot charge a lot of waste tires inside the incinerator, so the combustion time is not long, so the incineration of waste tires cannot continuously supply heating water and hot water. In order to operate the auxiliary burner, the charging cycle of the waste tire is short, and the maintenance cost of the boiler device is high.

In order to solve this problem, Patent Registration No. 10-0247294 (name of the invention: waste tire combustion device for waste incinerator) was provided.

The waste tire combustion device for the conventional waste incinerator is generally cylindrical, and the inner wall is installed on the upper part of the body made of refractory bricks so as to open and close a lid made of refractory, and the lower part of the body has an air spray pipe connected to the blower. A primary combustor having a gas supply chamber, a combustion chamber, and a backflow passage connecting the communication pipes with the communication pipes interposed therebetween so as to form an incinerator by installing a ignition device connected to the controller; Secondary combustor composed of long cylindrical pipes are connected in order, and the air inlet pipe connected to the blower is installed in the communication path and the reverse flow path of the primary combustor, and the temperature sensing sensor connected to the controller in the combustion chamber of the first and second combustors. By installing a normal burner, it is characterized in that it is to be used as a heat source of waste incinerators or industrial boilers.

Such a conventional invention does not cause an environmental pollution during incineration of waste tires by allowing the unburned gas generated during incineration of waste tires to completely burn while passing through the first and second combustors. Not only can the high temperature be obtained, but also the external factors that occur during the incineration of the waste tires, when the temperature of the first and second combustors drops below the appropriate temperature, the burner operates to maintain the proper temperature which is always needed. Waste heat generated during incineration of waste synthetic resin can be used as a heat source for various industrial boilers and waste incinerators.

However, in the related art, the incomplete gas generated in the incinerator is supplied into the primary combustor to communicate with the gas supply chamber, the communication path, the combustion chamber, and the backflow path, so that the space in which the incomplete gas stays inside cannot be secured. The incomplete gas is not completely incinerated as it is supplied to the combustor.

The present invention has been made in order to solve such a conventional problem, an object of the present invention is to configure the air supply line to allow the incomplete gas generated in the incinerator during incineration of waste tires and waste synthetic resin to stay and delay in the burner To provide a high-temperature combustion burner for incinerators configured for complete incineration.

Another object of the present invention is to treat residual organic pollutants (Phlorinated Biphenyls: PCB _C ) included in insulating oils and smooth oils of electrical equipment by using high temperature (high temperature) generated from a high temperature combustion burner.

The problem solving means of the present invention is the waste tire and the synthetic resin is in communication with the incinerator is incinerated, incomplete gas of the incinerator is introduced into the incineration furnace to complete the combustion process to supply high-temperature heat to the after-stage equipment A combustion burner, wherein the high temperature combustion burner includes: a body part having an incinerator mounting flange mounted on an incinerator and a rear end installation mounting flange mounted on a rear end equipment; A gas supply chamber and a gas combustion chamber connected to the inside of the body by a horizontal passage and connected to a vertical connection passage; And an air supply device provided in the body portion, the horizontal passage and the vertical connection passage region to delay and guide the incomplete gas supplied from the incinerator to the gas supply chamber to the gas combustion chamber.

According to the present invention, the incomplete gas generated in the incinerator at the time of incineration of the waste tire and the synthetic resin is supplied to the inside of the high temperature combustion burner to sufficiently stay and delay, and then is supplied to the gas combustion chamber to completely incinerate as the high temperature (high temperature) of the oil burner. As it is treated, a complete gas supply is provided to the rear end equipment, providing a benefit to the environment.

In addition, the present invention provides an effect of protecting the environment by treating the residual organic pollutants contained in the insulating oil, smooth oil of the electrical equipment by using the high temperature (high heat) generated in the high-temperature combustion burner.
