Description

Incineration boiler with improved waste heat recovery efficiency and maintainability {A TRASH BOILER IMPROVED THE EFFICIENCY OF WASTE HEAT RECOVERY AND THE ABILITY OF MAINTENANCE AND MANAGEMENT}

The present invention relates to an incineration boiler with improved waste heat recovery efficiency and maintainability, and more particularly, to improve the recovery rate for the waste heat generated during the combustion of combustible waste such as waste tires, waste vinyl or waste plastic, and The present invention relates to an incineration boiler having improved waste heat recovery efficiency and maintainability to prevent foreign substances contained in exhaust gas generated in a process from being adsorbed in a pipe.

In general, the amount of tires, vinyls and plastics used in daily life is significantly increased, and after being used, only a part of them are recycled, and most of them are classified as waste and landfilled or incinerated.

Since the method of landfilling of the wastes causes problems of securing landfills and contamination of groundwater and land by landfilled wastes, methods of disposing wastes by incineration have been intensively discussed.

In other words, the method of incineration of waste generates toxic exhaust gas and soot in the incineration process, which causes air pollution. Therefore, the solution of the incineration process and the high temperature heat generated in the incineration process immediately cause heat pollution. In addition, since a large amount of heat energy is wasted, recovery measures for waste heat generated during combustion are being discussed.

In this case, the waste heat recovery apparatus for recovering waste heat mainly uses a method of obtaining hot water by bringing hot heat generated in a combustion process into contact with cold water to transfer the heat to cold water. That is, a method of causing heat exchange between the hot water and the cold water by causing the hot air to flow around a tube through which cold water passes, or a method of causing heat exchange between hot and cold water by storing cold water around the tube through which the hot water passes. .

However, these prior arts had the following problems.

That is, in the combustion process of waste fuel, not only hot heat but also exhaust gas is generated. Such exhaust gas contains a large amount of foreign matter in various particle forms such as dust. Therefore, there is a problem in that the exhaust gas is adsorbed on the surface of the tube to prevent heat exchange between heat and water with long time use.

In order to solve this problem, it is necessary to periodically clean the pipe surface. However, in order to improve heat exchange efficiency, the contact area between heat and water must be increased. Therefore, even when the heat passes around the tube through which the water passes or, conversely, when the water passes around the tube through which the heat passes, a large number of tubes should be provided so that the diameter of the tube is small and close.

In this state, the removal of foreign substances adsorbed on the outside or inside of many tubes is not only very cumbersome and difficult, but also the inner diameter of the tubes is generally small and curved, so that the operation is not practical in many cases. Therefore, the waste heat recovery device not only significantly reduces the waste heat recovery efficiency as the service life is increased, but also has a problem in that a large amount of maintenance costs are required for removing foreign matters or replacing a pipe that cannot remove foreign matters.

In more detail, the water tank 210 is made in the form of a tub and connected to the water supply pipe 211 for supplying water to the upper portion and the drain pipe 213 for discharging hot water heated by waste heat is connected to the lower portion. .

The waste heat supply pipe 220 is disposed through the water tank 210 at the central portion of the water tank 210. One end of the waste heat supply pipe 220 is in communication with the first exhaust pipe 114 through which the high temperature heat and exhaust gas discharged from the combustion furnace 110 pass, and the other end is in communication with the waste heat receiving chamber 230.

The waste heat return pipe 240 is installed through the water tank 210 around the waste heat supply pipe 220. The waste heat return tube 240 is connected to the waste heat receiving chamber 230 so that hot heat and exhaust gas can pass therein, and the other end of the waste heat exhaust chamber formed at the other end of the water tank 210 ( 260).

The waste heat exhaust chamber 260 is a space in which heat and exhaust gas passing through the waste heat return pipe 240 are collected, and is discharged to the outside air along the second exhaust pipe 270 through the exhaust pump 280. Although not shown in the drawing, the second exhaust pipe 270 is preferably equipped with a filtration and dust collector so that the exhaust gas is exhausted in a purified state.

A second cleaning door 263 may be provided.

On the other hand, the waste heat return pipe 240 is provided with a foreign material removal unit 250 for preventing the foreign matter by the exhaust gas is adsorbed in the waste heat return pipe 240. In other words, the exhaust gas is generated by burning the pellet formed by processing the combustible waste as a fuel, and contains a large amount of foreign matter in the form of dust or particles. Such foreign matter is contained in the exhaust gas and is exhausted with high temperature heat. The exhaust gas is slowed down or the exhaust gas is adsorbed to the inner circumference of the tube while contacting the inner circumference of the tube. When the amount of adsorption of such foreign substances increases, heat is prevented from being transferred to the water in the water tank 210 through the waste heat return pipe 240. Therefore, in the present invention, the foreign matter removal unit 250 is provided to increase the waste heat recovery rate by preventing the adsorption of foreign matter on the waste heat return pipe 240.

In more detail, the foreign matter removing unit 250 is to prevent the adsorption of foreign matter by the screw-type rotation, the rotary shaft 251 disposed along the inside of the waste heat return pipe 240 and the rotary shaft ( Screw 252 is mounted to the 251, and the rotating means for penetrating the waste heat receiving chamber 230 and is connected to the rotary shaft 251 to rotate the rotary shaft 251.

At this time, the rotating means may be provided in various forms, in the present embodiment adopts a drive method by a chain. That is, the rotating means includes a rotary sprocket wheel 253 connected to the rotary shaft 251, a drive sprocket wheel 254 driven by a motor 255, and the rotary sprocket wheel 253 and a drive sprocket wheel ( It is composed of a chain (256) connecting the 254 to transfer the rotational force of the drive sprocket wheel 254 driven by the motor 255 to the rotary sprocket wheel (253).

The arrangement of the drive sprocket wheel and the rotary sprocket wheel, the method of connecting the chain to the drive sprocket wheel and the rotary sprocket wheel, and the rotation direction of the drive sprocket wheel and the rotary sprocket wheel are illustrated in FIG. Here, the plurality of rotating sprocket wheels 253 sequentially connected to the chain 256 with respect to one driving sprocket wheel 254 requires a rotational force for rotating the rotating shaft 251 on which the screw 252 is mounted. However, since the screw 252 is rotated at a low speed so as to remove and transport a small amount of foreign matter adsorbed and delay the passage of heat, the required rotational force is quite small. Therefore, even if a plurality of rotary sprocket wheels 253 are driven by one drive sprocket wheel 254, there is no problem in achieving the object of the present invention.

On the other hand, the space outside the waste heat receiving chamber 230 in which the rotary sprocket wheel 253 is installed protects the rotary sprocket wheel 253 and the chain 256 from rain or external dust and the like for the insulation of the outside air. The side plate 257 is provided and partitioned from the outside. At this time, the second side plate 257 is preferably provided to be disassembled for the inspection and repair of the rotating means, the cleaning of the screw 252 and waste heat supply pipe 220.

In addition, the foreign matter removal unit 250 as described above may be provided in the waste heat supply pipe 220 to remove foreign matter adsorbed on the waste heat supply pipe 220.

Next, the operation of the incineration boiler with improved waste heat recovery efficiency and maintainability according to the present invention will be described.

Waste fuel processed into pellets of the small particles through the screw conveyor 171 is supplied to the hopper 173 of the fuel injection means 170, the fuel supplied to the hopper 173 is driven by a screw (drive) of the motor 179 177 is rotated and is injected onto the grate 115 through the fuel injection hole 153 of the blowing chamber 150. When a predetermined amount of fuel is injected onto the grate 115, the igniter 190 operates to inject a gas flame from the nozzle 191 to ignite the fuel.

When the waste fuel is ignited in this manner, the reduction motor 131 of the blower 151 and the grate rotating means 130 is operated to blow external air into the blower chamber 150, while the grate 115 Slowly rotating, combustion proceeds. At this time, the outside air blown into the blowing chamber 150 is supplied onto the grate 115 through the blowing hole 155 and the plurality of blowing holes 157 at the blowing pressure. Therefore, combustion occurs and the grate 115 receives oxygen from the air introduced through the blower hole 157 to promote combustion, and the grate 115 rotates slowly by the grate rotating means 130 while the external air is evenly distributed. The air is blown to increase fuel efficiency, thereby providing an environment in which fuel is completely burned.

As the combustion progresses, the motor 255 of the fuel injection means 170 rotates to inject an appropriate amount of fuel, and the hot heat and exhaust gas generated during the combustion process are collected through a waste heat recovery device through the first exhaust pipe 114 of the combustion chamber ( 200).

The waste heat supply pipe 220 communicates with the first exhaust pipe 114 so that the high temperature heat and exhaust gas discharged from the combustion furnace 110 through the first exhaust pipe 114 pass through the waste heat supply pipe 220. It is moved to the receiving chamber (230). In this case, since the waste heat supply pipe 220 passes through the water tank 210, the hot heat may be supplied as water stored in the water tank 210.

The heat and exhaust gas moved to the waste heat receiving chamber 230 enter the waste heat return tube 240 disposed around the waste heat supply pipe 220 while the path is changed in the waste heat receiving chamber 230. At this time, the flow of heat and exhaust gas is guided by the exhaust pump 280 provided in the second exhaust pipe (270). That is, the exhaust pump 280 induces a flow of air from the second exhaust pipe 270 to the outside, so that the heat and exhaust gas introduced into the waste heat supply pipe 220 pass through the waste heat receiving chamber 230 through the waste heat return pipe 230. It is entered (240).

At this time, the waste heat return pipe 240 is provided with a rotating shaft 251 and a screw 252. Therefore, the heat and exhaust gas entering the waste heat return pipe 240 passes through the waste heat return pipe 240 while the path is changed to zigzag as indicated by arrows in FIG. 4 by the screw 252. Accordingly, heat exchange between the high temperature heat passing through the waste heat return pipe 240 and the water stored in the water tank 210 is made more smoothly.

On the other hand, the rotary shaft 251 is installed in the waste heat transfer pipe 240 may be rotated by the rotating means. That is, the rotary sprocket wheel 253 connected to the rotation shaft 251 is rotated in one direction by being connected through the chain 256 and the drive sprocket wheel 254 driven by the motor 255. At this time, since the rotary sprocket wheel 253 is connected to the rotary shaft 251, the rotary shaft 251 is rotated together with the rotation of the rotary sprocket wheel 253.

The screw 252 is driven by the rotation of the rotation shaft 251. The driving of the screw 252 prevents the foreign matter contained in the exhaust gas from being adsorbed to the waste heat return pipe 240 while passing through the waste heat return pipe 240. That is, the end of the screw 252 is installed in contact with the inner wall of the waste heat transfer pipe 240, the screw 252 scrapes the waste heat while scraping off the foreign matter adsorbed to the waste heat transfer pipe 240 by the exhaust gas It serves to transfer to one side of the pipe (240).

Therefore, even if the waste heat recovery apparatus 200 according to the present invention is used for a long time, almost no adsorption of foreign substances is made in the waste heat return tube 240, so that the heat exchange between the hot air and the water of the water tank 210 is always at a constant high efficiency. It can be done.

In addition, since foreign matter is prevented from adsorbing to the waste heat return pipe 240, the foreign matter removal work for the waste heat return pipe 240 is hardly required. Therefore, as in the prior art, the inconvenience of regularly cleaning the pipe through which exhaust gas passes can be eliminated.

In addition, the screw 252 is in contact with the inner circumference of the waste heat return tube 240 to remove the foreign matter, the screw 252 is also heated by hot heat passing through the waste heat return tube 240. Therefore, the heat transmitted to the screw 252 is also transferred to the water in the water tank 210 through the waste heat return pipe 240, thereby improving the waste heat recovery efficiency.

On the other hand, the heat and exhaust gas passing through the waste heat return pipe 240 is collected in the waste heat exhaust chamber 260 and exhausted to the outside air through the second exhaust pipe 270 according to the flow guided by the exhaust pump 280. At this time, the exhaust gas discharged to the second exhaust pipe 270 flows into the filtration and dust collector and is purified and then exhausted into the atmosphere.

During this process, the cold water is supplied to the water tank 210 through the water supply pipe 211. The cold water is heated by recovering waste heat while exchanging heat with hot air passing through the waste heat supply pipe 220 and the waste heat return tube 240. And the heated hot water is drained through the drain pipe 213 provided at the bottom of the water tank 210 is transferred to where the hot water is needed.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. It is self-evident.
