Description

  The present invention relates to a soot removing device that removes soot generated when soot is burned.

A stone kiln that performs cooking by burning firewood or the like generally has a chimney in the upper part of the stone kiln. In this chimney, the heat of the stone kiln is conducted and exposed to the high temperature, and exposed to the low temperature. Smoke is exhausted using the rising airflow generated by the differential heat from the part.
In addition to smoke evacuation using natural convection as described above, there are those that place a blower at the end of a smoke conduit extending from a stone kiln and suck out smoke, and those that use a cyclone suction device. When using an exhaust fan like this, in order to suppress contamination that accumulates or accumulates on the mechanism part of the fan or the smoke exhaust path due to smoke, a filter is placed in the middle of the smoke conduit or near the source of the smoke. It removes soot and oil contained in the flue gas.

In particular, stone kilns and the like generate high-temperature smoke, so when performing flue gas, a metal mesh filter or the like is used. For example, a heating cooker described in JP 2009-297391 A An exhaust duct is provided above the heating means of the grill cabinet, and a smoke removal filter is installed at the center of the grill cabinet top plate, that is, at the suction port of the exhaust duct. This smoke removal filter is made of a platinum catalyst and is configured to obtain a filtering effect by being heated by high-temperature smoke.
In addition, an aqua filter or the like that removes fats and oils by introducing smoke generated during heating into water is also used in a heating cooking apparatus such as a stone kiln.

Japanese Patent Application No. 2009-297391

When soot or the like burns, soot of various sizes is generated, and smoke ranging from particulate to a size that can be grasped with a finger is included. In addition, relatively large soot may be broken when high-temperature smoke moves due to convection or the like, and its size and shape change during the exhaust of smoke.
Therefore, when trying to adsorb particulate wrinkles by reducing the mesh of the mesh filter that filters the wrinkles, clogging easily occurs due to adsorption of large-sized wrinkles. In addition, in order to avoid such clogging due to large wrinkles, there is a problem that it becomes impossible to adsorb particulate wrinkles when the mesh of the mesh filter is enlarged.

  In addition, the aqua filter must have a configuration in which a smoke conduit is connected to the bottom of the water tank in order to pass smoke into the water, and the aqua filter main body including the water tank is installed at a high place in order not to deteriorate the smoke emission efficiency. It is preferable. Furthermore, since it is necessary to frequently replace the water in the water tank dirty by filtering, there is a problem that a place where a water supply / drainage pipe can be laid has to be secured and the installation cost becomes high. .

  The present invention has been made in order to solve the above-mentioned problems, can efficiently absorb soot, and can be installed in a place where maintenance is easy to perform. An object of the present invention is to provide an apparatus for removing wrinkles that can be suppressed.

  In addition, a plurality of the nickel filters are disposed on the smoke movement path.

  Further, the air volume adjusting unit adjusts the wind speed of the smoke passing through the nickel filter to 0.3 m / sec. It is characterized by adjusting to.

  Further, the present invention is further characterized by further comprising an outside air introduction unit that mixes outside air with the smoke that has passed through the nickel filter and lowers the temperature of the smoke.

  The main body includes the smoke suction portion and the smoke discharge portion on an upper end surface, and the nickel filter is disposed below the upper end surface and between the smoke suction portion and the smoke discharge portion. The smoke sucked from the smoke suction part descends along one inclined surface of the inner wall of the main body and passes through the nickel filter, and the smoke that has passed through the nickel filter passes to the other inclined surface of the inner wall of the main body. It is formed so that it may rise along and it will be discharged | emitted from the said smoke discharge part.

  According to the present invention, smoke containing soot passes through the nickel filter having a three-dimensional network structure at a predetermined wind speed, so that the soot can be efficiently adsorbed on the filter surface while suppressing soot crushing. Moreover, since the soot adhering to the nickel filter can be easily washed away, the filtering performance can be easily maintained.

The main body 10 of the soot removing device 1 has the above-described nickel filter 23 in a two-layered manner as described above, and is arranged so as to be two-layered in the direction of smoke movement. Yes. Specifically, as shown in FIG. 3 (a), the smoke is disposed below the smoke suction part 11 and the smoke discharge part 12, and on the smoke path moving from the smoke suction part 11 to the smoke discharge part 12, Two nickel filters 23 are arranged so as to overlap each other. In addition, as shown in FIG. 3C, two nickel filters 23 are arranged in the vertical direction of the main body 10, and a total of four nickel filters 23 are built in the main body 10. The nickel filter 23 is supported so as to stand on the plane of the bottom end portion 13 inside the main body 10.

Further, the nickel filter 23 is supported by a support mechanism unit (not shown) so that it can be freely inserted into and removed from the main body 10.
Here, a total of four nickel filters 23 are disposed, but the number of filters disposed in the vertical direction of the main body 10 and the number of filters disposed on the smoke movement path are respectively described above. It is not limited to quantity.

The door 14 is attached to the main body 10 so as to be freely opened and closed by, for example, a hinge (not shown), and is configured such that four nickel filters 23 can be inserted or removed in the open state shown in FIG.

As shown in FIG. 3A, the main body 10 has a bottom end 15 below the door 14 formed horizontally, and side surfaces 16 and 17 arranged on the sides of the bottom end 15 in the figure. The shape is inclined and the lower end portion of the main body 10 is narrowed down. The side surface 16 is disposed below the smoke suction port 11, and the side surface 17 is disposed below the smoke discharge port 12, and a similar inclined surface is formed inside the main body 10.

Next, the operation will be described.
In order to heat the stone kiln 5, when putting firewood etc. in the kiln inside the stone kiln 5 and burning it, the exhaust fan 7 installed outdoors is operated. The exhaust fan 7 sucks the inside of the smoke conduit 3, the soot removing device 1, and the smoke conduit 2. Preferably, suction is performed including the inside of the exhaust hole 5 b of the stone furnace 5.
When soot is burned inside the stone kiln 5, the generated smoke rises due to convection generated by heat such as combustion and is sucked into the exhaust port 5 a of the stone kiln 5. At this time, soot contained in the smoke is also sucked into the exhaust hole 5 b from the exhaust port 5 a and proceeds to the smoke conduit 2 through the chamber 4.

  The smoke in the pipe of the smoke conduit 2 descends in the vertical direction and is sucked into the soot removal device 1 from the smoke suction port 11 via the FD 20. Smoke sucked from the smoke suction part 11 moves downward inside the main body 10 and hits the side face 16 and is guided by the inclination of the side face 16 to gradually move toward the side where the smoke discharge part 12 is provided. Change and pass through the nickel filter 23. The smoke that has passed through the nickel filter 23 rises inside the main body 10, is discharged from the smoke discharge port 12, and travels into the pipe of the smoke conduit 3.

  In other words, the smoke generated in the stone kiln 5 travels downward in the figure from the smoke suction port 11 shown in FIG. 3A, that is, travels vertically downward along the inner wall of the main body 10 and strikes the side surface 16. . The smoke changes its direction to the right in the drawing along the inner surface of the side surface 16, that is, the inclined surface 16 a forming the inner wall of the main body 10, and passes through the nickel filter 23. The smoke that has passed through the nickel filter 23 turns upward along the inclined surface 17a that forms the inner wall of the right side surface 17, that is, the inner wall of the main body 10, and rises toward the upper end surface 13. Then, it is discharged from the smoke discharge port 12.

As described above, when the smoke traveling inside the main body 10 passes through the nickel filter 23, the soot contained in the smoke is adsorbed by the nickel filter 23 and rises toward the smoke discharge port 12. Will be removed.
Here, when the soot contained in the smoke is filtered by the nickel filter 23, 0.3 [m / sec. ] Smoke is allowed to pass at the air velocity passing through the filter surface. Preferably, 0.3 [m / sec. ] Pass at the following wind speed. At such a wind speed, the soot is suppressed from being pulverized into fine particles, and a relatively large size soot can be adsorbed on the filter surface. Further, fine wrinkles can be adsorbed to the filter portion having a three-dimensional network structure, and wrinkles can be effectively removed.

  The wind speed of the smoke passing through the nickel filter 23 is determined by the exhaust fan 7 and the FVD 21. The exhaust capacity of the exhaust fan 7 is that at least the smoke on the suction side of the nickel filter 23 built in the main body 10 can be sucked through the smoke conduit 3, and the air flow rate through the filter surface as described above is generally large. Smoke smoke as you get. In this way, when the exhaust fan 7 is operating, the FVD 21 adjusts the opening degree of its own damper so that smoke that has passed through the nickel filter 23 with a preset air volume is discharged from the smoke discharge port 12. . In other words, the flow rate of the smoke discharged from the main body 10 to the smoke conduit 3 is adjusted, and the wind speed of the smoke passing through the nickel filter 23 is set to a predetermined value, that is, 0.3 [m / sec. ] To control.

The smoke from which the soot has been removed by passing through the nickel filter 23 is mixed with the outside air introduced into the main body 10 from the FVD 22 disposed on the inclined surface 103, and the temperature of the smoke is lowered to reduce the exhaust temperature. Are exhausted from the exhaust fan 7 as safe.
When smoke generated when burning soot in the stone kiln 5 is guided to the soot removing device 1 through the smoke conduit 2, the temperature of the smoke reaching the soot removing device 1 is about 65 [° C.] to 70 [° C. ]become. The outside air introduced into the inside of the main body 10 from the FVD 22 is mixed with the smoke having such a temperature, and the temperature of the smoke discharged to the smoke conduit 3 is cooled to about 40 [° C.].
For example, when the effective filter area of the nickel filter 23 is 0.405 [m ² ], the air discharger 7 so that the air flow rate passing through the filter surface is 0.405 × 0.3 × 3600 = 437.4 [CMH]. To move the smoke. Further, when smoke is passed through the nickel filter 23 with such an air volume, if the outside air from the FVD 22 is mixed and the temperature is lowered, the total exhaust air volume discharged from the exhaust fan 7 through the smoke conduit 3 is 2000. It becomes ˜2400 [CMH].

The soot removal device 1 of the present embodiment emits smoke at 0.3 [m / sec. ], Or the soot having various shapes and dimensions contained in the smoke can be efficiently adsorbed to the nickel filter 23 by passing it through the nickel filter 23 of the three-dimensional mesh metal porous body at a passing wind speed of less than that. Moreover, since the nickel filter 23 is passed at a slow wind speed as described above, soot can be filtered while being crushed into particles, and soot can be removed from the smoke with high efficiency.
In addition, the soot removing device 1 is configured so that the nickel filter 23 is double disposed on the smoke movement path inside the main body 10 so that the smoke containing soot passes through the two nickel filters 23. Many wrinkles can be removed.

Further, the smoke inlet 11 and the smoke outlet 12 are provided on the upper end surface 13 of the main body 10 and the main body 10 is formed so that the nickel filter 23 is disposed below them. be able to. In other words, it is possible to reduce the space for installing the soot removing device 1, and it is possible to install the soot removing device 1 in a place where maintenance is easy.
Furthermore, by installing the soot removing device 1 in a place where maintenance can be easily performed, it becomes easy to remove the nickel filter 23 with soot from the main body 10 and clean it. Since the soot adhering to the nickel filter 23 can be washed away relatively easily with water or the like, for example, by washing the nickel filter 23 every time the soot is burned in the stone kiln 5, the filtering performance of the nickel filter 23 is deteriorated. Prevent and maintain efficient removal of soot.
