Description

Incineration apparatus for exhaust gas reduction

The present invention relates to a smoke reduction incineration apparatus.

With the increase of population and the development of industry, the amount of food waste, general waste, and industrial waste is also increasing rapidly, and various pollution caused by these is becoming a social issue, and the legal safety standards for disposal and disposal of these wastes are prepared. This is strictly regulated, and academia and industry are conducting a lot of research and steadily studying the means and methods of treatment.

Waste treatment methods include landfill, reclamation, and incineration, but premodern landfill methods have limitations due to the absolute shortage of landfills and environmental pollution due to undecomposed waste and leachate.

Therefore, the incineration method that can greatly reduce the waste and make effective use of the waste heat is currently preferred as the main treatment method, but exhaust gas is generated when the waste is burned. Exhaust gas has a problem of generating environmentally harmful substances due to unburned incomplete combustion, and the hazardous substances generated by incineration are dioxins, nitrogen oxides (NOx), sulfur oxides (SOx), and hydrocarbons (CxHx) which are classified as poisons. Etc. can be mentioned.

There are several types of dust collection methods to avoid releasing hazardous substances into the atmosphere. For example, a method of collecting exhaust gas by a filter, an electric dust collecting method in which dust is charged by giving a certain amount of electric charges to discharge static electricity, and the exhaust gas is rotated at a very high speed to collect a heavy specific gravity by hitting an outer wall. Cyclone dust collection method.

In case of collecting harmful substances by using a filter, the cost of purchasing increased because a dedicated filter was used.

In the flue part 30, the flue part 30 is arrange | positioned (not shown). The exhaust gas of the combustion chamber may be discharged to the outside of the smoke reduction incineration device 1 through the flue part 30 by driving the fan. However, 휀 disposed in the flue 30 may be omitted. In this case, the fan may be arranged in the combustion chamber. The exhaust gas can flow by driving the combustion chamber 실.

The door 25 is disposed at one side of the filter housing 21. The flow space 211 may be opened by opening the door 25.

The drum 22 includes a drum body 221 and a partition 222.

The drum body 221 is disposed in the flow space 211 and is disposed in a direction perpendicular to the direction in which the exhaust gas flows. The drum body 221 is formed with a filter space 221a penetrating in the longitudinal direction therein. The surface of the drum body 221 is perforated to form drum holes connecting the filter space 221a and the flow space 211. Accordingly, the exhaust gas of the flow space 211 flows through the filter space 221a and is discharged to the outside of the filter housing 21.

The partition wall 222 is positioned in the filter space 221a and is arranged along the circumferential direction with respect to the virtual center of the drum body 221 to partition the filter space 221a into a plurality of spaces. The surface of the partition 222 is perforated. The partitioned plurality of filter spaces 221a may be connected to each other through barrier rib holes of the barrier rib 222. Accordingly, the exhaust gas flowing into the filter space 221a by flowing the flow space 211 in the combustion chamber 11 flows through the filter space 221a divided through the partition wall hole and then passes through the drum hole to the flue part 30. Can be introduced.

Meanwhile, the shaft 223 connected to the partition wall 222 protrudes from the virtual center of the drum body 221. The shaft 223 is rotatably coupled to the support 224 disposed around the interior of the filter housing 21. However, the support 224 can be omitted. In this case, the shaft 223 may be coupled to rotate directly around the inside of the filter housing 21.

The driver 24 includes a motor. The driving unit 24 is disposed at the other side of the filter housing 21 and connected to the shaft 223. The drum body 221 may rotate in the filter space 221a by the driving of the driving unit 24.

The filter net 23 includes a filter body 231 and a filter cover 232 and is disposed in each divided filter space 221a and filters harmful substances contained in exhaust gas flowing through the filter space 221a.

Inside the filter body 231 is a shell space 231a penetrating along the longitudinal direction. However, one side of the filter body 231 may be open and blocked on the other side. The surface of the filter body 231 is perforated to form a plurality of filter holes. The shell space 231a of the filter body 231 is connected to the filter space 221a through the filter hole. The size of the filter hole may be formed less than 5mm. The exhaust gas flowing through the filter space 221a may flow into the filter body 231 through the filter hole and then flow back into the filter space 221a through the filter hole.

The filter cover 232 is detachably coupled to both sides of the filter body 231. The filter cover 232 and the filter body 231 is connected in a variety of separate coupling structure, such as fitting method, screw method. When the other side of the filter body 231 is blocked, the filter cover 232 may be coupled to be separated on one side of the filter body 231. Although not shown in the drawings, filter holes may be formed in the filter cover 232.

The shell space 231a accommodates a filter medium F for filtering harmful substances contained in the exhaust gas. The filter medium F may include shells such as cockles, clams, swamps, oyster shells and shellfish. The shell is crushed into 5 to 30 mm in size after heat treatment. When the shell size is less than 5 mm, the gap formed between neighboring shells is narrow, and the shell space 231a may be blocked. This causes a problem that the flow of exhaust gas is not made smoothly. If the size of the shell exceeds 30mm, the space between neighboring shells is increased, so that the exhaust gas flows smoothly, but the filterability is reduced.

Hazardous substances contained in the exhaust gas introduced into the shell space 231a may be adsorbed by the shell. The exhaust gas from which the harmful substances have been removed may be discharged to the outside of the filter housing 21 through the filter body 231 and the drum body 221. In addition, since the drum 22 is rotated by the driving unit 24, harmful substances may be evenly adsorbed on the shell.

Meanwhile, the filter net 23 may be drawn out of the filter housing 21 from the filter space 221a in the state in which the door 25 is opened. At this time, the filter cover 232 may be opened and the shell which is the filter medium F may be replaced.

The filter unit 20 according to the present embodiment may further include a guide 26.

The guide 26 is located in the flow space 211 and is disposed between the incineration portion 10 and the drum 22. The drum 22 guides the exhaust gas of the combustion chamber 11 to flow into the filter net 23. With the arrangement of the guides 26, the lower flow space 211 of the drum 22 is narrower than the diameter of the drum 22. The exhaust gas introduced from the combustion chamber 11 in the arrangement of the guide 26 may flow into the filter space 221a through the drum hole.

The filter unit 20 according to the present embodiment may further include a blocking member 27.

The blocking member 27 is disposed in the guide 26 to be in contact with the outer circumference of the drum 22. The blocking member 27 blocks the flow of exhaust gas between the outer circumference of the drum 22 and the inner circumference of the filter housing 21. By the arrangement of the blocking member 27, the exhaust gas is discharged only through the filter space 221a.

The following describes the operation of the soot reduction incinerator described above.

The door of the incinerator 10 is opened to inject waste to be incinerated into the first space of the combustion chamber 11 to incinerate with a heat source provided by the burner. At this time, the exhaust gas generated while the waste is incinerated by the driving of the fan may flow into the flow space 211 of the filter housing 21.

The exhaust gas of the flow space 211 is guided to the drum 22 by the guide 26 and flows into the drum 22 which is being rotated by the driving unit 24. That is, the exhaust gas of the flow space 211 flows into the filter space 221a through the drum hole. The exhaust gas of the filter space 221a flows into the shell space 231a through the filter hole. At this time, the harmful substances contained in the exhaust gas may be adsorbed by the shell filling the shell space 231a.

In the case of oyster shells, the main component is calcium carbonate (CaCO3), which also contains some silicon and magnesium.

In the case of oyster shells, the internal, external and cross-sectional structures are different. Outer surface Inner surface has a layered structure in which a thin plate shape is layered, and in the outer surface, a hexagonal or quadrangular plate-like face is densely shared with each other. Also, in the case of a cross section, there is an empty space between the layer and the layer having a nano size thickness. Hazardous substances contained in the exhaust gas can be filtered while the exhaust gas passes through the empty space and odor components contained in the exhaust gas can be decomposed while the exhaust gas passes through the empty space.

Therefore, the exhaust gas generated in the combustion chamber 11 passes through the filter unit 20, and at this time, the exhaust gas passes through the filter material F formed of a shell, and harmful substances contained in the exhaust gas are adsorbed to the filter material F. Hazardous odors decompose. Accordingly, the exhaust gas from which harmful substances and harmful smells are removed may be discharged to the outside of the smoke reduction incineration device 1 through the flue part 30 through the filter part 20.

On the other hand, since the drum 22 is rotated by the drive unit 24, while the filter medium F moves in the shell space 231a, harmful substances may be evenly adsorbed on the surface of the filter medium F. This may increase the efficiency of removing harmful substances and odors.

In addition, when the removal efficiency of harmful substances and harmful smells decreases, the door 25 may be opened to draw out the filter net 23 from the filter space 221a. The filter medium F used by separating the filter body 231 and the filter cover 232 may be recovered, and a new filter medium F may be introduced into the shell space 231a. Since the filter medium (F) can be replaced, the efficiency of removing harmful substances and odors can be increased.

In addition, by using the smoke reduction incinerator to dry dead oysters, abalone, etc., it is possible to prevent the occurrence of odor generated by decay.

In the above description and drawings, the filter part of the present invention is disposed between the incineration part and the flue part to remove harmful substances contained in the exhaust gas generated by the waste incineration. It can filter out harmful substances contained in sewage.
