Description

A trash boiler waste gas purifier

The present invention relates to an incineration boiler which obtains heating and industrial hot water by incineration of combustible waste waste such as waste wood or trash, and more specifically, the combustion gas and soot generated during incineration of combustible waste waste in a combustion chamber. The present invention relates to an exhaust gas purifying apparatus of an incineration boiler which completely dissipates toxic gases by blowing the exhaust gas discharged through the convection and the exhaust gas discharged through the communication into the combustion chamber and combusting it again at high temperature.

In general, as a method of treating flammable waste such as waste waste or waste waste, there is a method of disposing of waste in a specific area or by incineration, and in case of landfill, it is necessary to secure a large area for landfilling many wastes. As land pollution causes serious environmental pollution such as land and groundwater, recently, a method of incineration of flammable waste has been adopted.

Incineration furnaces for incineration of combustible wastes such as waste wood and trash are manufactured and used in various forms according to their use, and most of them are used for heating or industrial hot water by using waste heat generated during incineration of waste. Recyclable structures predominate.

As such, a typical incineration boiler for recycling waste heat generated by incineration of flammable waste has a door in which a combustible waste is input, a grate in which the input waste is loaded and burned and a door for discharging the burned incinerator to the outside. In addition, a waste heat exchange chamber containing water is installed around the inner wall of the combustion chamber in order to recycle the waste heat generated during the incineration process.

Applicant has disclosed a technology related to incineration boilers to prevent environmental pollution by condensing combustion gas and soot generated in the process of incineration of waste waste in the combustion chamber, and collecting soot discharged to the atmosphere, to Korean Utility Model Registration No. 0324846. I have registered.

The incineration boiler proposed by the present applicant is configured to convection the combustion gas and the soot generated in the incineration process from the upper part of the combustion chamber to the lower grate, so that the combustion gas and the soot are combusted again. It consists of a structure that collects the exhaust fumes.

However, the existing incineration boiler of this structure can reduce the emission of soot by collecting the smoke to some extent, but the exhaust gas that is harmful to the human body and acts as the main cause of air pollution is not released through a separate purification device and is released as it is. There was a problem causing serious environmental pollution.

The present invention was devised to solve the problems of environmental pollution due to the exhaust gas of the existing incineration boiler as described above. The combustion gas and soot generated in the incineration process of combustible waste waste are condensed in the combustion chamber to be completely combusted while communicating. It is an object of the present invention to provide an incineration boiler exhaust gas purification apparatus that completely exhausts toxic gases harmful to humans and causes air pollution by blowing exhaust gas discharged into a combustion chamber and burning it again at high heat.

The present invention for achieving the above object is a conventional incineration boiler, the convection hole configured to convection combustion gas and soot through one side of the combustion chamber up and down; A chamber connected to an upper portion of the communication and equipped with a trapping network and a blocking plate fitted therein and having an exhaust port; An exhaust passage installed on the chamber and through which exhaust gas is discharged; A blower connected to and installed at an upper portion of the communication in the chamber and operated by driving of a motor; One side is connected to the bottom surface of the opposite side of the blower in the chamber and the other side is connected to the lower portion of the combustion chamber;

In the present invention, the body 10 of the incineration boiler may be generally manufactured in a cylindrical or rectangular structure, and the internal combustion chamber 11 includes a waste heat exchange chamber 12 in which water is received on an inner wall to obtain waste heat. A grate 13 is installed on the lower side of the bottom of the 11 to burn the waste, and a door 14b for treating the burned material is provided on the lower side of the grate 13, while the front of the main body 10 is provided. In the upper portion, doors 14a and 14c for introducing waste waste into the combustion chamber 11 are provided, and an air vent 15 through which external air necessary for combustion flows into the combustion chamber 11 is formed.

In the above, the present invention constitutes a convection hole 16 in which combustion gas and soot convex on the inner wall of the combustion chamber 11. The convection hole 16 is formed by penetrating one inner wall of the combustion chamber 11 up and down. The convection hole 16 is formed to penetrate through the outer side of the waste heat exchange chamber 12 from the upper inner wall of the combustion chamber 11 to the lower inner wall where the grate 13 is located.

Therefore, the convection hole 16 is a convection gas and combustion gases in a high temperature state generated during the combustion process as shown in Figure 2 of the drawing convection from the upper side of the combustion chamber 11 through the convection hole 16 to the lower side where the grate 13 is located. Here, incompletely burned combustion gas and soot are gradually extinguished as they are burned again.

The toxic gas is extinguished as it is blown to the lower part and burned again by the high heat of the combustion chamber 11, and a part of the toxic gas passes through the collecting network 21 and is discharged to the exhaust tube 24 through the exhaust port 23.

That is, the exhaust gas discharged into the chamber 20 through the communication 17 from the combustion chamber 11 is blown by the wind blown from the air vent 31 and is pushed toward the opposite side where the exhaust tube 24 and the air duct 40 are located. The light gas with a specific gravity is discharged into the exhaust tube 24 through the particulate collecting network 21 and the exhaust port 23, and the toxic gas with a relatively high specific gravity is blown under the blowing pressure and installed in the bottom of the chamber 20 (40). By being blown to the lower part of the combustion chamber 11 through), the combustion chamber 11 is burned again at high heat and extinguished.

Therefore, the exhaust gas discharged into the atmosphere through the exhaust cylinder 24 reduces the environmental pollution by discharging the toxic gas, and the soot and the agent collected in the trap 21 are wind blown from the tuyeres 31. It is shaken by the flow into the combustion chamber 11 through the blower tube 40, and by adjusting the opening and closing range of the exhaust port 23 to the blocking plate 22 to adjust the discharge amount of the exhaust gas.
