<<1st Embodiment>>
FIG. 1 is a configuration diagram of a dust collector 1 according to the first embodiment. Moreover, FIG. 2 is a cross-sectional schematic diagram which shows the dust collector 1 shown in FIG. Note that FIG. 2 omits the description of the control device 80 (the same applies to FIGS. 3 and 4, which will be described later). As shown in FIGS. 1 and 2, the dust collector 1 includes an intake port 10, a processing chamber 20, an exhaust port 30, a shock wave generator 40, a branching mechanism 50, a screw conveyor 60, and a dust discharge port. 70 and a controller 80 .

The intake port 10 is connected to, for example, an incinerator or a boiler of a power plant, and exhaust gas generated in the incinerator or boiler is introduced into the processing chamber 20 via the intake port 10 .

The processing chamber 20 is hollow inside and communicates with the outside through an air inlet 10 and an air outlet 30 . As a result, the exhaust gas introduced from the intake port 10 passes through the internal space of the processing chamber 20 and is discharged from the exhaust port 30 to the outside. A fan may be provided near the exhaust port 30 in order to flow the exhaust gas.

A shock wave output section 21 for outputting a shock wave branched by a branching mechanism 50 (to be described later) to the internal space of the processing chamber 20 is formed in the upper portion of the processing chamber 20 . In this embodiment, a shock wave generator 40 for generating shock waves and a branching mechanism 50 for branching the shock waves generated by the shock wave generator 40 and transmitting them to the shock wave output unit 21 are arranged above the processing chamber 20 . be done. The shock wave generated by the shock wave generator 40 is branched by the branching mechanism 50 and transmitted to the shock wave output section 21 , and output by the shock wave output section 21 to the internal space of the processing chamber 20 . Note that the shock wave output unit 21 according to this embodiment is an opening that communicates the internal space of the processing chamber 20 and the branching mechanism 50 .

The dust collector 1 according to the first embodiment is intended for dust collection, and in order to increase the dust collection efficiency, the flow velocity of the exhaust gas at the intake port 10 is set to 4 to 12 m / sec, and the exhaust gas in the inner space of the processing chamber 20 is preferably 1 to 4 m/sec. Further, it is preferable that the flow velocity of the exhaust gas at the exhaust port 30 is 5 to 10 m/sec. Thus, by making the flow velocity of the exhaust gas in the inner space of the processing chamber 20 slower than the flow velocity of the exhaust gas in the intake port 10 or the exhaust port 30, the flow velocity of the exhaust gas can be changed and the shock wave can be attenuated. The effect of suppressing the noise of shock waves can be obtained.

In the present embodiment, the shock wave output unit 21 is formed on the ceiling of the processing chamber 20 , so the shock waves output from the shock wave output unit 21 are output from the top to the bottom of the processing chamber 20 . It collides from above with the exhaust gas flowing in the internal space of the. Suspended particulate matter in the exhaust gas has mass, so it receives shock waves from above and falls downward. Further, in the present embodiment, the shock wave generator 40 generates a shock wave by burning fuel in the internal combustion engine to cause an explosion, so the shock wave output to the processing chamber 20 has a high temperature. As a result, the moisture adhering to or bound to the suspended particulate matter in the exhaust gas is subdivided by the pressure of the shock wave and evaporates due to the heat of the shock wave and the repeated positive and negative pressure of the shock wave (pressure wave), resulting in water vapor. , and is discharged to the outside through the exhaust port 30 together with the gaseous components of the exhaust gas.

Furthermore, in this embodiment, as shown in FIGS. 1 and 2, three shock wave output units 21 are arranged side by side along the flow direction of the exhaust gas. The shock waves generated by the shock wave generator 40 are branched into three by the branching mechanism 50 , output from the three shock wave output units 21 respectively, and collide with the exhaust gas flowing in the internal space of the processing chamber 20 . In this way, by arranging a plurality of shock wave output units 21 side by side along the flow direction of the exhaust gas, it is possible to increase the frequency at which the exhaust gas flowing in the internal space of the processing chamber 20 collides with the shock wave. It becomes possible to separate contained suspended particulate matter with high efficiency. In this embodiment, three shock wave output units 21 are provided and the branching mechanism 50 branches the shock wave into three. The number is not limited to three, but may be, for example, two, or four or more.

The lower part of the processing chamber 20 has a collecting part 22 for collecting the dropped particulate matter, and one end of the collecting part 22 is connected to a dust outlet 70 for discharging the particulate matter accumulated in the collecting part 22 . doing. Further, in the present embodiment, a screw conveyor 60 is installed in the accumulating section 22, and the particulate matter accumulated in the accumulating section 22 is conveyed to the dust outlet 70 by the screw conveyor 60, and is discharged from the dust outlet 70 to the outside. is discharged to Particulate matter such as soot discharged from the dust discharge port 70 can be hardened into pellets, for example, and reused as fuel.

Furthermore, in the processing chamber 20 according to the present embodiment, a partition plate 23 can be provided between the shock wave output units 21 arranged in the flow direction of the exhaust gas. In the internal space of the processing chamber 20, the partition plate 23 is formed so as to spread over the entire width direction of the processing chamber 20 (Y direction in FIGS. ), or a configuration having a partial gap in the width direction of the processing chamber 20 is also possible. In addition, the partition plate 23 extends in the height direction of the processing chamber 20 (the Z direction in FIGS. 1 and 2) in the internal space of the processing chamber 20, and is between the bottom surface or the top surface of the processing chamber 20. A relatively narrow gap is formed. By providing the partition plate 23 in this way, it is possible to change the flow velocity of the exhaust gas in the internal space by changing the cross-sectional area of the exhaust gas in the internal space of the processing chamber 20 . Specifically, as shown in FIG. 2, the flow path immediately after being introduced into the internal space of the processing chamber 20 from the intake port 10, the flow path between the partition plates 23, and the exhaust from the internal space of the processing chamber 20 Let CS1 be the cross-sectional area of the flow channel immediately before discharging to the port 30, and CS2 be the cross-sectional area of the flow channel from the tip of the partition plate 23 to the bottom or top surface of the processing chamber 20. The cross-sectional area CS1 is It is formed wider than the area CS2 (for example, twice or more), so that the flow velocity in the channel having the cross-sectional area CS1 is lower than the flow velocity in the channel having the cross-sectional area CS2. In the present embodiment, in the internal space of the processing chamber 20, the flow path having the cross-sectional area CS1 and the flow path having the cross-sectional area CS2 are alternately repeated. As a result, noise and shock waves are attenuated, and the noise caused by the output of the shock waves can be suppressed. Furthermore, in the present embodiment, by providing the partition plate 23, the flow path of the exhaust gas is lengthened, so the frequency with which the shock wave collides with the exhaust gas can be increased. In this embodiment, the flow velocity of the exhaust gas in the channel having the cross-sectional area CS1 is preferably 1 to 2 m/sec, and the flow velocity of the exhaust gas in the channel having the cross-sectional area CS2 is 2 to 4 m/sec. is preferred. By installing the partition plate 23 in this way, it is possible to reduce the noise caused by the shock wave to 100 db or less.

The shock wave generator 40 is a device for generating shock waves, and in this embodiment, a generator having an internal combustion engine such as an engine generator is used. As such an internal combustion engine, a gasoline engine, a diesel engine, a Stirling engine, a pulse jet engine, etc. can be used. , a diesel engine and a Stirling engine are preferred, and more preferably a gasoline engine or a diesel engine, which is a Stirling engine, a two-stroke engine or a four-stroke engine that can use woody biomass fuel as fuel.

The shock wave generator 40 generates a shock wave by burning fuel in the internal combustion engine and causing an explosion. The number of explosions of the shock wave generator 40 is not particularly limited. can. By setting the number of explosions to 20 to 100 times per second, interference between shock waves can be greatly reduced, and dust collection efficiency can be improved.

Further, as shown in FIG. 1, the shock wave generator 40 communicates with the shock wave output section 21 of the processing chamber 20 via the branch mechanism 50, and the shock wave generated by the shock wave generator 40 propagates through the branch mechanism 50. Then, it is output from the shock wave output unit 21 to the inside of the processing chamber 20 . The branching mechanism 50 is, for example, a pipe, one end of which is connected to the shock wave generator 40, and the other end of which is branched into three. It is connected to the three shock wave outputs 21 of the chamber 20 . Thereby, the branch mechanism 50 can transmit the shock waves generated by the shock wave generator 40 to the processing chamber 20 . Further, in the present embodiment, it is preferable that the cross-sectional area of the exhaust port 30 is five times or more the sum of the cross-sectional areas of the three shock wave output portions 21 . In this way, by setting the cross-sectional area of the exhaust port 30 to be five times or more the total cross-sectional area of the shock wave output section 21, it is possible to prevent an excessive amount of shock waves from being output with respect to the flow rate of the exhaust gas. Noise can be reduced.

The controller 80 controls the operations of the shock wave generator 40 and the screw conveyor 60 . Specifically, the control device 80 can control the number of explosions of the shock wave generator 40 and the rotation speed of the screw conveyor 60 . For example, when the object to be treated is exhaust gas as in the present embodiment, the control device 80 can increase the dust collection effect by controlling the number of explosions of the shock wave generator 40 to 20 to 100 Hz. The control device 80 is connected to a fan (not shown) to control the operation of the fan, thereby controlling the temperature of the internal space of the processing chamber 20 and the flow speed of the exhaust gas flowing through the internal space of the processing chamber 20. can also be If the shock wave generating device 40 is a generator, the control device 80 can be configured to operate using electricity generated when the shock wave generating device 40 generates shock waves.

As described above, in the dust collector 1 according to the present embodiment, when the exhaust gas passes through the processing chamber 20, the shock wave (pressure wave) generated by the explosion in the shock wave generator 40 and exceeding the speed of sound is generated in a substantially horizontal direction. By colliding with the flowing exhaust gas from above, solid objects with a relatively large mass contained in the exhaust gas are hit downward and fall, and a high dust collection effect can be exhibited. In addition, if the suspended particulate matter contained in the exhaust gas contains water, or if the suspended particulate matter has water attached to it or combined with it, the high-temperature shock waves will break up such water into fine water droplets that do not get wet. It can evaporate and separate the suspended particulate matter from solid and gas, and the moisture can also be discharged from the exhaust port 30 together with the exhaust gas.

Although not shown, the dust collector 1 is connected to a heat recovery device through the exhaust port 30, and the heat recovery device recovers heat from the exhaust gas discharged through the exhaust port 30. It is possible. As a result, in the dust collector 1 according to the present embodiment, suspended particulate matter such as soot can be collected from high-temperature exhaust gas generated in an incinerator, a boiler of a power plant, etc., and can be reused as fuel. It is possible to recover heat from high-temperature exhaust gas and use it for carbonization or semi-carbonization of biomass fuel, heating facilities, etc.

Next, an example of the dust collector 1 according to this embodiment will be described. In the dust collector 1 according to the present embodiment, a 4-cycle gasoline engine was used as the shock wave generator 40, and the dust collection effect was measured by causing an explosion of 10 to 50 Hz per second. Specifically, a dust collector that does not have the shock wave generator 40 and collects dust with a bag filter, and a dust collector that does not have the shock wave generator 40 and collects dust with a cyclone system. as a comparative example, the weight of the dust collected by the dust collector 1 according to the present embodiment was measured and compared. In the comparative example and the working example, the conditions of the exhaust gas were the same, and the exhaust gas having the same concentration of dust discharged from the foundry and the galvanizing plant was circulated at the same flow rate to collect the dust. As a result, in the dust collector 1 according to the present embodiment, the dust collection effect is 4 to 6 times higher than that of the dust collector of the comparative example using the bag filter, and 2 to 3 times higher than that of the cyclone type dust collector. A double dust collection effect was confirmed.

As described above, the dust collector 1 according to the first embodiment is a separation device for separating suspended particulate matter contained in exhaust gas from the exhaust gas, and is provided between the intake port 10 and the exhaust port 30. , a processing chamber 20 having a certain space through which the exhaust gas passes; a shock wave generator 40 having an internal combustion engine; The processing chamber 20 includes a shock wave output unit 21 for outputting the shock wave branched by the branching mechanism 50 to the internal space of the processing chamber 20, and a floating object that has received the shock wave. and an accumulation portion 22 where particulate matter is accumulated, and a plurality of shock wave output portions 21 are arranged side by side in the flow direction of the exhaust gas. As a result, in the dust collector 1 according to the first embodiment, the suspended particles contained in the exhaust gas can be dropped by colliding with the shock wave, so compared to conventional bag filters and cyclone dust collectors , can collect dust with high efficiency. In particular, in the dust collector 1 according to the first embodiment, the plurality of shock wave output units 21 are arranged side by side along the flow direction of the exhaust gas. It will collide with, and it becomes possible to raise dust collection efficiency more. In addition, since the dust collector 1 according to the first embodiment can be configured without using a filter such as a bag filter, there is no need to lower high-temperature exhaust gas to 200 ° C. or less, which is the heat resistant temperature of the bag filter. , the heat can also be recovered with high efficiency. The recovered heat can be used to burn biomass fuel such as wood, to carbonize or semi-carbonize wood, or to supply heating equipment. Furthermore, even if the exhaust gas contains moisture, the impact of the high-temperature shock waves on the exhaust gas causes the moisture contained in the exhaust gas to become finer, evaporate, and be discharged together with the exhaust gas. It can be easily separated and can also function as a highly efficient drying device.

In addition, in the dust collector 1 according to the first embodiment, by partitioning the inner space of the processing chamber 20 with the partition plate 23, it is possible to repeatedly change the flow velocity, and the noise caused by the shock wave can be reduced by the pressure wave caused by the change in the flow velocity. It can be suppressed to 100 db or less. Furthermore, in the present embodiment, by providing the partition plate 23, the flow path of the exhaust gas is lengthened, so the frequency with which the shock wave collides with the exhaust gas can be increased.

Furthermore, in the dust collector 1 according to the first embodiment, the shock wave generator 40 can be configured to use biomass fuel. In this case, the internal combustion engine of the shock wave generator 40 has an input port for inputting biomass fuel, and by burning the biomass fuel input from the input port, it is possible to generate shock waves. Thereby, in the dust collector 1, renewable biomass fuel can be effectively used, and consumption of fossil fuel can be reduced. Further, in the dust collector 1 according to the present embodiment, a diesel engine or a gasoline engine having a stroke mechanism, which are relatively easily available, can be used as an internal combustion engine, so that it is relatively inexpensive and noiseless. A suppressed dust collector 1 can be provided. In addition, by using a diesel engine or a gasoline engine, it is possible to partially change the configuration of a conventional bag filter type dust collector. Furthermore, in the dust collector 1 according to the first embodiment, the cross-sectional area of the exhaust port 30 is five times or more the sum of the shock wave output cross-sections of the three shock wave output units 21. A large amount of shock waves can be prevented from being output, and noise can be reduced (for example, reduced to 100 dB or less). In addition, in the dust collector 1 according to the first embodiment, the shock wave generator 40 generates 20 to 1000 shock waves per second due to the explosion, thereby increasing dust collection efficiency.

<<Second embodiment>>
Next, a second embodiment of the invention will be described. In the second embodiment, a solid-gas separation device 2 that separates solid substances from a liquid containing solid substances, such as waste liquid, will be described as an example.

In addition, in the solid-gas separation device 2 according to the second embodiment, solid matter contained in the waste liquid is accumulated in the accumulation unit 22 and dust is discharged by the screw conveyor 60 by causing the waste liquid to collide with the shock wave to separate solid and gas. In addition to discharging from the outlet 70, the water contained in the waste liquid is solid-gas separated and discharged as water vapor (fine water droplets) from the exhaust port 30. It has similar configuration and operation.

The liquid-feeding pipe 90 is a pipe for feeding the waste liquid to the processing chamber 20 , and the fed waste liquid is sprayed into the inner space of the processing chamber 20 from a nozzle 91 formed in the liquid-feeding pipe 90 . be. Further, as shown in FIG. 3, the liquid feed pipe 90 is arranged in the upper part inside the processing chamber 20, and the waste liquid is sprayed downward from the nozzle 91. As shown in FIG. The discharged liquid sprayed from the nozzle 91 collides with the high-temperature shock wave output from the shock wave output section 21 arranged further above. As a result, the liquid contained in the waste liquid is fragmented by the shock waves, and is evaporated by the heat of the shock waves to become water vapor (fine water droplets), which is discharged from the exhaust port 30 to the outside. Solid matter contained in the liquid drops and accumulates in the accumulation section 22 below the processing chamber 20 due to the shock wave.

Also in the second embodiment, the number of explosions of the shock wave generator 40 is not particularly limited, and can be 20 to 1000 times per second. It is preferable to increase the number of explosions more than the number of explosions of the dust collector 1 . For example, in the dust collector 1 according to the first embodiment, if the number of explosions is 20 to 100 times per second, in the solid-gas separation apparatus 2 according to the second embodiment, the number of explosions is 20 to 1000 times. and more preferably 100 to 1000 times. In particular, as in the second embodiment, when the object to be treated has a large amount of moisture such as waste liquid, or the moisture is difficult to remove, the number of explosions of the shock wave generator 40 should be 300 to 1000 Hz. is preferred.

As described above, in the solid-gas separation apparatus 2 according to the second embodiment, the high-temperature shock wave collides with the waste liquid introduced into the processing chamber 20 through the liquid feed pipe 90, thereby evaporating the liquid contained in the waste liquid. This enables solid-gas separation to separate the solid matter contained in the waste liquid.

<<Third embodiment>>
Next, a third embodiment of the invention will be described. In the third embodiment, a solid-gas separation device 3 that separates solids from semi-solids such as mud containing liquids and solids will be described as an example.

The transport path 110 is a path for transporting sludge to the processing chamber 20, and as shown in FIG. Further, the screw conveyor 100 conveys the sludge to the inner space of the processing chamber 20 on the conveying path 110 . While the screw conveyor 100 conveys the sludge, part of the sludge falls from the respective holes 111 of the conveying path 110, and while falling, the sludge collides with the shock wave output from the shock wave output unit 21 and is dispersed. At the same time, the heat of the shock wave evaporates the moisture and separates the solids from the solids, thereby dropping the solids onto the accumulating portion 22 and accumulating them.

Also in the third embodiment, the number of explosions of the shock wave generator 40 is not particularly limited, and can be 20 to 1000 times per second. It is preferable to increase the number of explosions than the number of explosions of the dust collector 1 according to . On the other hand, since sludge has a lower moisture content than waste liquid, it is preferable to make the number of explosions smaller than the number of explosions of the solid-gas separation device 2 according to the second embodiment. Specifically, as in the third embodiment, when the object to be treated has a medium moisture content such as sludge, the control device 80 can set the number of explosions of the shock wave generator 40 to 100 to 300 Hz. preferable.
