[0011]
The automatic switching valve 8 is a three-way valve provided at the junction of the fuel oil pipe 6 and the waste liquid supply pipe 7. When the temperature detected by the temperature sensor 16 is equal to or lower than a predetermined set temperature, the waste liquid supply pipe 7 The pipe line is automatically switched so that the fuel oil is supplied to the combustor 5 by the fuel oil pipe 6 when the side is cut off, and when the predetermined set temperature is exceeded, the upstream pipe 6a of the fuel oil pipe 6 The organic solvent waste liquid W2 is automatically switched from the waste liquid supply pipe 7 to the combustor 5 through the downstream pipe 6b of the fuel oil pipe 6.
[0012]
Although the distillation apparatus 9 is not shown with respect to accessories such as a pump and a storage tank, the organic solvent waste liquid W2 from the organic waste discharge source W introduced into the waste liquid supply pipe 7 is converted into the regeneration heat exchanger. The fuel oil pipe 6 is heated by exhaust gas passing through the exhaust duct 15 on the downstream side of 13 and the evaporated organic solvent vapor is cooled and condensed with cooling water, thereby purifying and concentrating the organic solvent liquid (organic component liquid). To the downstream side pipe 6b.
The duct 4 is provided with a concentrating device 17 on the upstream side and an intake air cooling device 18 on the downstream side (between the concentrating device 17 and the compressor 3).
[0013]
Although the concentrator 17 is not illustrated for an accessory device such as a blower, the organic component-containing air introduced into the inside by the duct 4 from the organic waste discharge source W is passed through the adsorbent layer in the adsorption treatment area, and the concentrator 17 The organic solvent gas W1 in the organic component-containing air is adsorbed on the adsorbent layer, and the exhaust gas passes through the branch duct (exhaust duct) 15a branched from the exhaust duct 15 on the downstream side of the regeneration heat exchanger 13 in the desorption treatment area.

As the concentrating device 17, a rotary concentrating device having an adsorbing rotor and capable of continuously repeating the adsorption and desorption can be preferably used.
[0014]
The intake air cooling device 18 forcibly supplies high-temperature organic component-containing air sent from the concentrating device 17 to the compressor 3 by cooling air blown from a fan 20 driven by an electric motor 19 through an air duct 21. The structure is composed of a flow rate of exhaust gas from the turbine 10 (primary fluid flow rate) flowing through the regeneration heat exchanger 13 and a flow rate of organic component-containing air to the combustor 5 (secondary fluid). Flow rate), and the flow rate (secondary fluid flow rate) of the organic component-containing air from the concentrator 17 flowing through the intake air cooling device 18 and the fan. 20 Since the flow rate of the cooling air from both (primary fluid flow rate) is substantially the same, the temperature of the fluid flowing through the inside is different, but it can be configured in the same manner as the regeneration heat exchanger 13, The regeneration heat exchanger 13 is used as an alternative.
[0015]
As shown in FIGS. 2 and 3, the regeneration heat exchanger 13 includes a rectangular parallelepiped box-shaped casing 22 having flanges 22a and 22b respectively connected to the inlet side and the outlet side of the primary fluid at both ends. Inside, a heat exchanger body 23 is mounted with a heat insulating material (buffer material) 24 having heat insulating properties such as ceramic wool interposed therebetween. The upper and other ends (primary fluid outlet chamber h2 side of the casing 22) (right side in FIG. 2) of the heat exchanger body 23 at one end side (primary fluid inlet chamber h1 side of the casing 22) (left side in FIG. 2). In the lower part of the pipe, there are a semi-cylindrical secondary fluid outlet header tank 25b and an inlet header tank 25a, respectively, in the width direction of the heat exchanger body 23 (the direction perpendicular to the paper surface in FIG. 2, left and right in FIG. The secondary fluid outlet chamber k2 and the secondary fluid inlet chamber k1 are formed by welding m or the like along the direction).
[0016]
Although not shown in detail in the heat exchanger body 23, for example, a plate that forms a flow path for guiding the primary fluid that has entered the primary fluid inlet chamber h1 of the casing 22 to the primary fluid outlet chamber h2, and the 2 A plurality of plates in which a flow path for guiding the secondary fluid introduced into the secondary fluid inlet chamber k1 to the secondary fluid outlet chamber k2 is alternately stacked in the width direction of the heat exchanger body 23. The secondary fluid and the secondary fluid exchange heat indirectly through the plates.
The regeneration heat exchanger 13 is connected to the primary fluid inlet chamber h1 of the casing 22 on the upstream side of the exhaust duct 15, and to the primary fluid outlet chamber h2 on the downstream side of the exhaust duct 15, The upstream side of the passage 12 is connected to the secondary fluid inlet chamber k1 of the inlet header tank 25a, and the downstream side of the passage 12 is connected to the secondary fluid outlet chamber k2 of the outlet header tank 25b.
[0017]
Further, when the regeneration heat exchanger 13 is used as an alternative to the intake air cooling device 18, the upstream side 21a of the air duct 21 is connected to the primary fluid inlet chamber h1 of the casing 22, and the primary fluid outlet. The downstream side 21b of the air duct 21 is connected to the chamber h2, and the upstream side 4a of the duct 4 is connected to the secondary fluid inlet chamber k1 of the inlet header tank 25a, and the secondary fluid outlet chamber of the outlet header tank 25b is connected. The downstream side 4b of the duct 4 is connected to k2.
In the regenerative heat exchanger 13, the heat exchanger body 23 is constituted by a plate-type heat exchanger. However, the present invention is not limited to this, and other types of heat exchangers may be used.
[0018]
Next, the operation of the organic component-containing air and waste liquid treatment apparatus according to the embodiment will be described.
When the gas turbine 2 is started, the temperature detected by the temperature sensor 16 is naturally lower than a set temperature (for example, 500 to 600 ° C.) for switching the flow path of the automatic switching valve 8, and the automatic switching valve 8 is connected to the fuel oil pipe 6 (6a). , 6b) to the combustor 5 of the gas turbine 2.
In this state, when a start command is issued by a switch such as an operation panel of the gas turbine 2, the compressor 3 of the gas turbine 2 is rotated, and a pilot fuel such as kerosene is combusted through the fuel oil pipe 6. 5 is sent to the pilot premixing pipe 5 and combusted. As a result, the turbine 10 is rotated by the combustion gas generated in the combustor 5 and the compressor 3 is rotated, so that the processing apparatus 1 is warmed up.
[0019]
After the warm-up operation with the pilot fuel, the generator 11 is connected to the turbine 10 via the speed reducer 11a and rotates to supply electric power E. In that case, the turbine 10 supplies the pilot fuel and the main fuel to the pilot premixing pipe and the main premixing pipe of the combustor 5 for combustion, and operates the processing apparatus 1 according to the required amount of electric power. .
Subsequently, for example, when a printing press (organic waste discharge source W) is operated in a printing factory, air (organic component-containing air) containing gaseous toluene (organic component) that is an organic solvent and toluene content are contained therein. Waste liquid (organic component-containing waste liquid) is generated, and air (organic component-containing air) of about 40 ° C. containing the gaseous toluene at a low concentration is sent to the concentrator 17 via the duct 4, and the organic component-containing air The concentration of toluene in the inside is increased, and the temperature is raised to about 150 ° C. and sent to the intake air cooling device 18. The organic component-containing air sent to the intake air cooling device 18 is sent from the fan 20 to the air duct. 21 After being cooled to about 50 ° C. with the cooling air blown through, the compressor 3 sucks and compresses the air and raises the temperature to about 190 ° C. This temperature was raised Contains organic components The air is heated to about 630 ° C. by the regeneration heat exchanger 13 and then sent to the combustor 5, whereby the fuel oil from the fuel oil pipe 6 is combusted by the combustor 5 to a high temperature (about 900 ° C.). The combustion gas is generated and the turbine 10 rotates, and the processing apparatus 1 starts the operation of processing the toluene-containing air and the toluene-containing waste liquid (organic component-containing air and waste liquid).
[0020]
Even when the operation of the processing apparatus 1 is started, the load of the gas turbine 2 is less than 70% of the total load (corresponding to the set temperature 500 to 600 ° C. at the inlet of the combustor 5 of the organic component-containing air). The automatic switching valve 8 does not switch the pipe line to the waste liquid supply pipe 7 side, the fuel oil is burned in the combustor 5, and high-temperature toluene in the organic component-containing air is burned by this high-temperature combustion gas. (Odor component) is decomposed and removed. Exhaust gas of about 650 ° C. exiting the turbine 10 passes through the exhaust duct 15 and heats the organic component-containing air from the passage 12 in the regeneration heat exchanger 13 to drop the temperature to about 240 ° C. A part is used as a heat source for heating the organic solvent waste liquid (organic component-containing waste liquid) sent to the distillation apparatus 9 from the organic waste discharge source W by being sent to the distillation apparatus 9, and the remainder is used for the exhaust duct 15. Heat is supplied to the concentrating device 19 through the branch duct 15a, and then joined to the exhaust duct 15 that has passed through the distillation device 9 and discharged out of the system.
[0021]
When the gas turbine 2 is started and its load exceeds 70%, the temperature of the organic component-containing air at the inlet of the combustor 5 exceeds the set temperature of the temperature sensor 16. From the command, the automatic switching valve 8 switches the pipeline so as to connect the waste liquid supply pipe 7 and the downstream pipe 6b of the fuel oil pipe 6 so that the toluene solution (organic component liquid) purified and concentrated by the distillation device 9 Is supplied to the combustor 5 through the waste liquid supply pipe 7 and the downstream pipe 6 b of the fuel oil pipe 6 and burned as fuel in the combustor 5. For this reason, both the toluene gas and the toluene solution are simultaneously burned in the gas turbine 2.
[0022]
During the operation of the processing apparatus 1, in the regeneration heat exchanger 13, high-temperature (about 630 ° C.) exhaust from the turbine 10 enters the primary fluid inlet chamber h 1 of the casing 22, while low temperature from the compressor 3. While the air (organic component-containing air) containing toluene gas (about 190 ° C.) enters the inlet header tank 25a and the heat exchange between the exhaust gas and the organic component-containing air is performed, the heat exchanger body 23 is Based on the temperature difference between the exhaust gas and the organic component-containing air, for example, as shown by the chain lines in FIGS. 2 and 4, temperature contour lines a (650 ° C.), b (630 ° C.), c (500 ° C.), d (370 ° C.), e (240 ° C.), f (240 ° C.), and g (190 ° C.).
[0023]
For this reason, as shown in FIG. 5, in the heat exchanger body 23, the primary fluid inlet chamber h1 is deformed to be larger than the primary fluid outlet chamber h2, and the inlet header tank 25a and the outlet header tank 25b On both sides in the width direction (left-right direction in FIG. 5), tensile stress i is on the side close to the primary fluid inlet chamber h1, and compressive stress b is on the opposite side, respectively, for the inlet header tank 25a and the outlet header. It acts in the length direction (vertical direction in FIG. 5) of the tank 25b. However, since the heat insulating material 24 is interposed between the casing 22 and the heat exchanger main body 23, the temperature gradient on the surface of the casing 22 is relaxed by the heat insulating material 24, and deformation of the casing 22 is suppressed. At the same time, the deformation of the casing 22 and the heat exchanger body 23 is separated. Thereby, compared with the case where the heat insulating material 24 is not provided, the thermal stress which arises in the welding part m with the said inlet header tank 25a, the outlet header tank 25b, and those heat exchanger main bodies 23 can be reduced significantly.
[0024]
According to the organic component-containing air and waste liquid treatment apparatus 1 according to this embodiment, the air containing the toluene gas (organic component-containing air) sent from the organic waste discharge source W to the compressor 3 of the gas turbine 2 is concentrated. Even if the temperature is raised by the concentration operation in the device 17, the intake air cooling device 18 is appropriately cooled, so that the output of the gas turbine 2 can be improved.
In addition, the intake air cooling device 18 is an air blown from a fan 20 using a heat exchanger having the same structure as the regeneration heat exchanger 13 for heating the organic component-containing air sent from the compressor 3 to the combustor 5. Since the organic component-containing air can be forcibly cooled, there is no need to manufacture the intake air cooling device 18 separately from the regeneration heat exchanger 13, and expensive heat exchange can be achieved by diverting the regeneration heat exchanger 13. The cost can be reduced by mass production. Further, the intake air cooling device 18 needs to provide a cooling heat source such as a refrigerator to directly cool the organic component-containing air by injecting pure water into the organic component-containing air or to obtain a primary side cooling fluid. Therefore, the incidental equipment of the processing apparatus 1 can be made inexpensive.
In this embodiment, the intake air cooling device 18 is a heat exchanger having the same structure as the regeneration heat exchanger 13 for heating the organic component-containing air sent from the compressor 3 to the combustor 5. May be different in size and ability. If the model is common, the parts constituting these heat exchangers are common, which can also reduce the cost by mass production. In particular, the intake air cooling device 18 and the regeneration heat exchanger 13 are connected to each other. The When the rate heat exchanger is used, the heat exchange capacity can be easily adjusted by increasing or decreasing the number of plates, and the cost reduction effect by mass production is more synergistic.
[0025]
Further, when the temperature of the organic component-containing air at the inlet of the combustor 5 of the gas turbine 2 is lower than a predetermined set temperature (for example, 500 to 600 ° C.) set in the temperature sensor 16, normal fuel oil such as kerosene is used. Since the toluene solution obtained by distilling the toluene waste liquid is sent to the combustor 5 to be combusted at the appropriate time when the temperature exceeds the preset temperature, both the toluene gas and the toluene waste liquid are removed from the gas turbine. Can be efficiently processed simultaneously by one processing apparatus 1 including two.
In addition, when the set temperature in the temperature sensor 16 is set lower than the predetermined set temperature when the processing apparatus 1 is started, the exhaust gas from the turbine 10 contains toluene gas or the like unburned and is discharged from the exhaust duct 15. However, since the set temperature of the temperature sensor 16 is appropriately set as described above, there is no such risk in the processing apparatus 1 of this embodiment.
[0026]
In addition, the exhaust from the turbine 10 can effectively increase the temperature of the organic component-containing air entering the combustor 5 in the regeneration heat exchanger 13, and the toluene waste liquid (toluene solution) from the distillation apparatus 9 can be removed. The fuel can be effectively recovered as the fuel in the combustor 5, and the fuel for operating the processing apparatus 1 can be saved.
Further, since the fuel oil burned in the combustor 5 can be properly used for kerosene or the like and the toluene solution, the gas turbine 2 is operated under a constant operating condition even when the processing amount of the toluene gas and waste liquid in the processing apparatus 1 is reduced. Therefore, a constant voltage can be secured by the generator 11.
[0027]
Further, when the operation and stop of the processing apparatus 1 are frequently performed in accordance with the operation and stop of the organic waste discharge source W that is frequently operated and stopped like a printing press, the gas turbine 2, the distillation apparatus 9 and the concentrator However, according to the organic component-containing air and waste liquid treatment apparatus 1 according to the embodiment, when the operation of the printing press is stopped, the automatic switching valve 8 is switched. Since the operation of the gas turbine 2 can be continued in the standby operation, the above problem can be solved.
[0028]
In the organic solvent gas / waste liquid treatment apparatus 1 according to each of the above-described embodiments, the fuel oil pipe 6 and the waste liquid supply pipe 7 are joined in the middle of the fuel oil pipe 6, and the automatic switching valve 8 comprising a three-way valve is formed at this joining portion. However, the fuel oil pipe 6 and the waste liquid supply pipe 7 are not joined but connected in parallel to the combustor 5, and an automatic on-off valve (switching means) is individually connected to the fuel oil pipe 6 and the waste liquid supply pipe 7. The automatic open / close valve may be linked and switched so that the other automatic open / close valve closes the pipe line when one of the automatic open / close valves communicates the line to the combustor.
[0029]
Further, the automatic switching valve 8 is not a simple flow path switching valve that stops the supply to the combustor 5 when one of the fuel oil and the toluene solution is supplied to the combustor 5. The fuel oil and the toluene solution can be switched to the combustor 5 and the supply ratio of the fuel oil and the toluene solution to the combustor 5 can be adjusted, and the toluene solution is sent to the combustor 5. During operation, when the toluene solution corresponding to the output of the gas turbine 2 can no longer be supplied, fuel oil is mixed into the toluene solution and supplied to the combustor 5 by adjusting the automatic switching mixing valve by the shortage. Also good.
Further, in the organic component-containing air and waste liquid treatment apparatus 1 according to each of the above embodiments, the air and waste liquid containing toluene are treated, but in the present invention, the organic component-containing air and waste liquid are air containing toluene, Not only waste liquid but also mixed solvent-containing air such as methanol, methyl ethyl ketone, isopropylene alcohol, and waste liquid can be treated.
[0030]
【The invention's effect】
As described above, according to the present invention, the following excellent effects are obtained.
According to the organic component-containing air and waste liquid processing apparatus according to claim 1, the organic component-containing air from the organic waste discharge source is concentrated by the concentrating device and cooled by the intake air cooling device, and is then supplied to the compressor of the gas turbine. While being sucked and sent to the combustor as organic component-containing air, the organic component-containing waste liquid from the organic waste discharge source is supplied to the combustor through the waste liquid supply pipe and burned in a timely manner, and the high temperature generated by this combustion Since the organic component-containing air and the organic component in the organic component-containing waste liquid are simultaneously decomposed and removed by the combustion gas, both the organic component-containing air and the organic component-containing waste liquid are simultaneously removed by a single processing device including a gas turbine. Can be processed efficiently.
[0031]
In addition, since the organic component-containing air heated and heated by the concentrator is cooled by the intake air cooling device and sent to the compressor, the high-temperature organic component-containing air is not sucked into the compressor, and the gas turbine The output can be improved.
Furthermore, since the intake air cooling device that cools the organic component-containing air has the same model as the heat exchanger for gas turbine regeneration, the components that make up these heat exchangers are common, and the cost can be reduced through mass production. .
Further, in the intake air cooling device, the primary side cooling fluid is air, and in order to directly cool the organic component containing air by injecting pure water into the organic component containing air or to obtain the primary side cooling fluid Since it is not necessary to provide a cold heat source such as a refrigerator, the incidental facilities of the processing apparatus can be made inexpensive.
[0032]
Also , Dark Since the exhaust heat from the turbine of the gas turbine is input to the compressor, the exhaust heat of the turbine can be used effectively, and the operating efficiency of the gas turbine (processing device) can be increased, and the concentrator can be heated separately. It is not necessary to add an apparatus, and the equipment cost of the processing apparatus can be reduced.
[0033]
Claims 2 According to the organic component-containing air and waste liquid treatment apparatus described in 1., the waste liquid supply pipe is provided with a distillation device, and the organic component-containing waste liquid is distilled in the distillation device by the exhaust heat of the turbine of the gas turbine. Because it is sent to the combustor as a liquid, the organic component waste liquid from the organic waste discharge source can be effectively recovered as the fuel in the combustor by the exhaust of the turbine, saving the fuel for operating the processing equipment can do.
Claims 3 According to the processing apparatus for organic component-containing air and waste liquid described in 1., the heat exchanger capacity can be easily adjusted by increasing or decreasing the number of plates by adopting a plate-type heat exchanger for the intake air cooling device and the regeneration heat exchanger.
