[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drying space or an air conditioning air which has a processing space for drying clothes and air conditioning and a processing function unit for generating drying air or air conditioning air. Involved in an air circulation system that is connected through a cycle flow path that circulates the gas to be treated, and in which a cyclone type dust collector is installed in the cycle flow path. Related to the technology for achieving this. The air circulation system targeted by the present invention is mainly suitable for a rotary drum type clothes dryer, a fixed type clothes dryer, an air conditioner, and an electric vacuum cleaner, but is limited to such ones. It is not necessary to do so, and it can be applied to any device / apparatus for removing dust from a gas (gas to be processed) including air containing dust.

2. Description of the Related Art (1) In a conventional integrated type washing machine, there is a direct contact water cooling system which is one of the methods for collecting thread waste, fiber dust and the like generated in the drying process. In this method, the air flow and the water flow are opposite flows in the heat exchanger,
Simultaneously with heat exchange, dust in the air is taken into the water stream to remove dust. In this case, the filtration type filter is not used.

(2) Japanese Patent Laid-Open No. 5-200185 discloses
The following technologies are proposed for the washer / dryer. In order to eliminate the problem that the lint filter gets wet and reduces the drying efficiency, the thread waste collected by drying during washing reattaches to the clothes, and the lint filter cannot be maintained unless the clothes are taken out. The detachable lint filter is arranged at an appropriate position.

(3) Japanese Patent Application Laid-Open No. 8-243292 discloses
The following technologies are proposed for the washer / dryer. A filter collects dust such as lint generated during drying.
Dust such as lint adheres to the inside of the filter. At the time of washing, the water drawn up by the pump is jetted in the opposite direction to the filter, and dust such as lint adhering to the filter is removed (backwashed) from the filter and placed between the water tank and the dehydration tank. It should be washed away. Therefore, cleaning becomes unnecessary,
Since the filter is not clogged, the drying efficiency can be improved.

(4) On the other hand, in an air conditioner, a filter having a mesh structure is generally installed at the suction port of an indoor unit, and this filter removes dust in the air for air conditioning.

(5) Japanese Patent Laid-Open No. 5-293323 discloses
The following technologies are presented for the air cleaning device. The contaminated air is branched and one of them is heated to be high temperature and high humidity air, and the other is cooled to be low temperature and high humidity air. Then, in the mixer, high-temperature high-humidity air and low-temperature high-humidity air are caused to collide with each other in a counterflow, and nuclear condensation of water vapor is generated with the pollutants contained in the air as nuclei to generate water droplets. To bloat. The water droplets adsorb pollutants contained in the air. Remove water droplets that have adsorbed contaminants with a filter, impinger or cyclone.

In the technique disclosed in Japanese Patent Laid-Open No. 5-293323, there is a problem in that the location where water droplets are generated by the nuclear condensation of water vapor is different from the location where the water droplets are removed, and the size of the apparatus becomes large.

(6) Japanese Utility Model Laid-Open No. 5-88645 has been proposed in order to solve the problem of increasing the size. The particulate separation and removal device disclosed in this publication is
This is for removing fine particles contained in the air in equipment such as a clean room that requires air cleaning. This particulate separation / removal device has a low temperature and high humidity air introducing pipe connected tangentially to the upper part of a cylindrical cyclone container body, and a high temperature and high humidity air introducing pipe communicating tangentially to the cyclone container main body below it. Connected,
A clean air discharge pipe is provided along the axial direction at the center of the cyclone container body, and a condensed water droplet discharge pipe is formed at the lower end of the cyclone container body. The low-temperature high-humidity air containing fine particles is introduced into the cyclone container body from the upper low-temperature high-humidity air introduction pipe, and the high-temperature high-humidity air containing fine particles is introduced into the cyclone container body from the lower high-temperature high-humidity air introduction pipe. Inflow. The low-temperature high-humidity air and the high-temperature high-humidity air swirl in the same direction in the cyclone container body. The low-temperature high-humidity air swirls while descending, and the high-temperature high-humidity air swirls while rising. While the low-temperature high-humidity air and the high-temperature high-humidity air meet on the way and swirl with adiabatic mixing, nuclear condensation of water vapor occurs with the particles as nuclei, and condensed water droplets grow and grow. The centrifugal force that accompanies swirling acts on the enlarged condensed water droplets, and the condensed water droplets move outward in the radial direction by the centrifugal force, collide with the inner peripheral wall surface of the cyclone container body, and are captured, along the inner peripheral wall surface. It then falls and is discharged from the condensed water droplet discharge pipe to the outside. On the other hand, the clean low-humidity air from which fine particles and water vapor have been removed flows out to the next stage through the clean air discharge pipe.

[0009]

In the heat exchanger of (1) described above, in which dust is removed by using an air flow and a water flow as opposed flows, the air flow and the water flow are brought into contact with each other linearly. Due to the small area, both heat exchange efficiency and dust collection efficiency are low. In order to have the required capacity, it is necessary to enlarge the heat exchanger, but this leads to an increase in the size of the entire equipment.

The distribution of the number of particles of dust, particularly fine particles of 1 to 25 μm, generated in the process of drying cotton cloth as actual clothes was measured in units of 5 μm with the flow rate as a parameter. An actual dryer was used for the experiment, and measurement was performed in the process of drying 3 kg of cotton cloth (when dried). The result is shown in Figure 1.
6 shows. The numerical value of 1.72 is the flow rate (m ³ / min)
And N is the number of samples. Fine particles of 1 to 5 μm have a frequency of occurrence of 50 to 80%, and 90 to 1 to 10 μm.
It was found to have a frequency of occurrence of%.

In an air cycle type dryer having a precise machine in the drying cycle, dust may enter the bearings of the rotating portion, which may cause troubles in the rotating portion.
It is necessary to collect 100% of dust of at least about 10 μm.

However, it is impossible to collect 100% of fine particles of about 10 μm only with the regenerative filter. By the way, when the highest performance filtration filter PS600 that can be recycled by washing with water is used, the collection capacity is about 80% for particles of 10 μm,
It was impossible to collect 100% of the particles.

Further, the size of dust that can be collected by the filtration type filter depends on the fineness of the filter, but it is inevitable that the pressure loss increases with the improvement of the collecting ability.

Then, the pressure loss increases with an increase in the collected amount (passage of the drying time) (see the solid line in FIG. 7). If the pressure loss increases, the operating efficiency of the device will decrease and the power consumption of the power source will increase.

From the above, it is difficult to improve the trapping ability and reduce the pressure loss when the filter of the above (3) is used.

Considering resource saving, it is preferable to recycle the filter rather than to dispose of it. However, if the filtration filter is to be regenerated, the maintenance of the filter becomes a burden on the user, and it is troublesome to take it out and wash it.

Further, regarding the air conditioner of the above (4), since the cross flow fan is used for the indoor unit, the suction port becomes wide, and the filter can be arranged in a large area, so the pressure loss should be kept low. Is possible.

However, in an air-cycle type or duct type (air pipe type) air conditioner, the pipe of the air circulation path connecting the equipment and the air-conditioned space is elongated in a pipe shape, so that dust discharged from the air-conditioned space is piped. Need to be removed in.
Therefore, it is difficult to arrange a large area filter. Placing a high-performance filter in the pipe increases pressure loss and makes maintenance very difficult.

Next, the above-mentioned (5) JP-A-5-2933.
In the case of the air purifying device of Japanese Patent No. 23, for the nuclear condensation,
Both high-temperature and high-humidity air introduced from above and low-temperature and high-humidity air introduced from below are made into a straight flow and collide with each other in a counter flow, so turbulence in the air flow is unavoidable and sufficient dust removal capability. In order to make full use of the above, it is inevitable that the device becomes large. Moreover, the dust removal location and the gas-liquid separation location are different, and in that sense, the size is increased.

On the other hand, the above-mentioned (6) actual opening flat 5-88645
The particulate separation / removal device of Japanese Patent Laid-Open Publication No. 2000-12075 is used to introduce high-temperature high-humidity air and low-temperature high-humidity air into the high-temperature high-humidity air introduction pipe and the low-temperature high-humidity air introduction pipe of the cyclone container body, respectively. It is necessary to divide the air discharged from the air by a distributor, and to guide one to a warming humidifier to make high temperature and high humidity air, and the other to a cooler to make low temperature and high humidity air. This necessitates a distributor, a heating / humidifying device, a cooler, and piping for connecting them to each other, resulting in a significant complication of the structure.

Further, in the cyclone container body of (6), since the swirling flow of the low-temperature and high-humidity air from above and the swirling flow of the high-temperature and high-humidity air from below are mixed, the downward swirling and the ascending Will cause a collision with the turn,
As a result, the smooth swirling flow is disturbed. Even if condensed water droplets grow due to nuclear condensation of water vapor with nuclei of adiabatic mixture due to adiabatic mixing, the swirling flow is disturbed and the centrifugal separation action becomes uncertain, and the inner wall surface of the cyclone container body of condensed water droplets becomes uncertain. Will be insufficiently captured due to collisions with. That is, there is a problem that the dust collection capability is not fully exhibited.

In particular, the introduction of high-temperature, high-humidity air having a low density from below has the following problems. Since the high temperature and high humidity air inlet is placed in the lower part and the low temperature and high humidity air inlet is placed in the upper part, the dust contained in the high temperature and high humidity air introduced from the lower inlet is centrifuged. In order to satisfactorily receive the collection by the cyclone container body, the size of the cyclone container body becomes large in order to secure the number of rotations.

The present invention was created in order to solve the above-mentioned problems, and it is an object of the present invention to improve the dust collecting capability and reduce the size.

[Means for Solving the Problems] FIG.
Air circulation system according to claim 1 according to the present invention, which wax has the following configuration. That is, the structure of an air circulation system in which the processing space and the processing function unit are connected via a cycle flow path for circulating the processing gas, and a cyclone type dust collector is interposed in the cycle flow path. It is assumed. And, as the cyclone type dust collector, a first treated gas introducing portion located at a higher order for introducing a treated gas of high temperature and high humidity containing dust, and a low temperature and high humidity containing less dust. It is characterized in that it is equipped with a second target gas introducing portion located at a lower position for introducing the target gas. According to this structure, there are the following effects. That is, in order to collect dust and water droplets contained in the gas to be treated, it is necessary that both dust and water droplets collide with the inner peripheral wall surface of the cyclone type dust collector while the gas to be treated is swirling. . However, dust is less dense than water droplets. Therefore, dust having a density lower than that of the water droplet needs to rotate more times than the water droplet. For that purpose, it is necessary to make the cyclone height higher for the hot and humid air containing dust. For this reason,
The first treated gas introducing part for introducing high temperature and high humidity air containing dust is arranged in the upper order, and the second treated gas introducing part for introducing low temperature, high humidity air not containing dust is in the lower order. The high temperature and high humidity air containing low density dust and high density water drops is rotated more, and the low temperature high humidity air including high density water drops but low density dust is The number of rotations is reduced and the dust removal and the gas-liquid separation are performed at the same time. As a result, the heat exchange efficiency is increased, the gas-liquid separation action is improved, and at the same time, the dust collection capability is also improved. Since the dust removal location and the gas-liquid separation location are the same location, the device can be downsized.

A second aspect of the present invention relates to a drying system, wherein the space to be treated is used as a drying working space, and a processing function section for generating drying air is provided, and the drying is performed with the structure of the first aspect. It is a system. As a drying system,
Exert function.

A third aspect of the present invention relates to an air conditioner system, wherein the treated space is an air-conditioned space, a processing function section for generating air for air conditioning is provided, and the air conditioner according to the first aspect is provided. It is a system. As an air-conditioning system, it exhibits the excellent functions and effects described above.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of an air circulation system according to the present invention will be described below in detail with reference to the drawings.

[Embodiment 1] Embodiment 1 relates to an air circulation type clothes drying system. FIG. 1 is a schematic configuration diagram of an air circulation type clothes drying system according to the first embodiment. In FIG. 1, reference numeral X indicates a cyclone type dust collector,
10 is a flow rate adjusting means, 11 is a drying drum as a drying action space (processed space), 12 is a blower, 13 is a heater, A indicated by a solid arrow is a drying cycle flow path, and B indicated by a broken arrow is a liquid flow path. is there. In the drying cycle flow path A, the outlet of the drying drum 11 is connected to the inlet of the cyclone dust collector X, and the outlet of the cyclone dust collector X is connected to the inlet of the blower 12. The outlet of the blower 12 is connected to the inlet of the heater 13, and the outlet of the heater 13 is connected to the inlet of the drying drum 11. The blower 12 and the heater 13 constitute a processing function section, and the processing function section and the drying drum 11 as a drying action space are connected via the drying cycle flow path A, and the cyclone type collecting path is provided in the drying cycle flow path A. The dust container X is installed. The gas to be processed which circulates and flows in the drying cycle channel A is air. The liquid flow path B, which is a separate system from the drying cycle flow path A, is connected to the cyclone type dust collector X, and the flow rate adjusting means 10 is provided upstream of the cyclone type dust collector X. The liquid flowing through the liquid flow path B is generally water, but is not limited to this.

FIG. 2 is a vertical sectional view showing a schematic structure of the cyclone type dust collector X. The cyclone dust collector X comprises a covered cyclone container body (outer cylinder) 1 composed of an upper right cylindrical portion 1a and a lower lower conical cylindrical portion 1b, and a central portion of the cyclone container main body 1. Is disposed concentrically on the upper part of the main body 1, and communicates with the clean gas discharge part (inner cylinder) 2 extending upward through the top plate part of the main body 1 in the tangential direction on the upper part of the cyclone container main body 1. The gas-to-be-treated introduction part (supply cylinder) 3 and the dust-containing liquid discharge part 4 formed at the lower end of the cyclone container body 1 are provided. The inner peripheral wall surfaces of the right cylinder portion 1a and the conical cylinder portion 1b of the cyclone container body 1 are made smooth so as not to hinder the smooth swirling of the air flow in the cyclone container body 1.

The cyclone type dust collector X of FIG. 2 is incorporated in the drying cycle flow path A of the air circulation type clothes drying system of FIG. In the cyclone dust collector X, the inflow port of the gas to be treated introduction part 3 is connected to the outflow port of the drying drum 11, and the outflow port of the clean gas discharge part 2 is connected to the inflow port of the blower 12.

Next, the operation of the air circulation type clothes drying system of the first embodiment configured as described above will be described.

The air blown by the blower 12 is heated by the heater 13 and is guided to the drying drum 11. The high-temperature air comes into contact with the clothes stored in the drying drum 11 and agitated as the drying drum 11 rotates, evaporates the moisture from the clothes, and performs a drying process on the clothes. The air containing water vapor becomes high temperature and high humidity air and is discharged from the drying drum 11. Dust such as yarn scraps separated from clothes in the drying process is also included in the high temperature and high humidity air and discharged from the drying drum 11.

The high-temperature and high-humidity air containing lint and other fine dust, water droplets, and steam discharged from the drying drum 11 is introduced into the cyclone type dust collector X from the gas to be treated introduction portion 3 of the cyclone container main body 1. It flows in and turns like a solid arrow. The following phenomena occur in the cyclone type dust collector X. The cooling liquid supplied from the liquid flow path B flows down on the inner peripheral wall surface of the cyclone container body 1.
The swirling high-temperature and high-humidity air and the flowing-down cooling liquid come into direct contact with each other to perform heat exchange, and the water vapor contained in the swirling high-temperature and high-humidity air is condensed to form water droplets. The air is cooled by heat exchange and the humidity is lowered by the condensation of water vapor. In a swirling air flow containing water droplets, condensed water adsorbs and collects fine dust. Further, the cooling liquid flowing down adsorbs and collects both fine dust and large dust. The dust and water droplets contained in the swirling air collide with the inner peripheral wall surface of the cyclone container body 1 by the centrifugal separation effect. A part of the cooling liquid that flows down also collides with the inner peripheral wall surface of the cyclone container body 1 due to the centrifugal force and flows down the inner peripheral wall surface. On the inner peripheral wall surface of the cyclone container main body 1, dust and water droplets in the swirling air flow are absorbed by the cooling liquid flowing down, and along with the liquid, the dust-containing liquid discharge part is transmitted along the inner peripheral wall surface of the cyclone container main body 1. 4 is discharged out of the system of the drying cycle channel A. The flow of the liquid flowing down the inner peripheral wall surface of the cyclone container body 1 is shown by a dashed arrow.

As described above, the high-temperature and high-humidity air containing dust introduced from the drying drum 11 is removed from water vapor, thread waste, and other fine dust to become clean low-humidity air.
It is discharged from the clean gas discharge part 2 and sent to the blower 4.

FIG. 3A shows a swirling flow p of high-temperature and high-humidity air swirling in the cyclone container body 1 and a cooling liquid flow q flowing down in the cyclone container body 1. For comparison, FIG. 3B shows the states of the straight air flow p ′ and the falling liquid flow q in the case of the conventional technique. The contact area of the swirling air flow p with the cooling liquid flow q flowing down in the constant path is more sufficient than the contact area of the parallel backflow straight air flow p ′ with the falling liquid flow q in the constant path as in the prior art. Is very large.

Therefore, in the air circulation type clothes drying system of the first embodiment, the heat exchange efficiency is increased and the dehumidification efficiency is improved. At the same time, the dust collecting ability is improved.
In this case, since the dust removal location and the gas-liquid separation location are the same location and the dust collection capability is improved, it is possible to downsize the device.

[Second Embodiment] The second embodiment relates to another aspect of the configuration of the cyclone type dust collector X, in which a cooling fluid passage is added. FIG. 4 is a schematic configuration diagram of the cyclone type dust collector X in the second embodiment. The same reference numerals as those in FIG. 2 for the first embodiment indicate the same components also in FIG. 4 for the present second embodiment. Briefly, 1 is a cyclone container body, 1a is a right cylindrical portion. 1b is a conical cylindrical portion, 2
Is a clean gas discharge part, 3 is a to-be-processed gas introduction part, 4 is a dust containing liquid discharge part, and their coupling relationship is also as described above, and therefore detailed description thereof is omitted here. In addition, Fig. 1 shows the overall configuration of the air circulation type clothes drying system.
This is similar to the case of the first embodiment shown in FIG. Matters that have been described in the first embodiment and that are not described again in the second embodiment are also applicable to the second embodiment as they are, and detailed description thereof will be omitted.

The specific configuration of the second embodiment is as follows. A cooling fluid passage 14 is provided inside the cyclone container body 1 of the cyclone dust collector X. The cooling fluid passage 14 may have any structure as long as it does not hinder the swirling of the high temperature and high humidity air inside the cyclone container body 1. For example, it is conceivable to use a spiral metal thin tube as shown in the figure. . The metal thin tube may be arranged in any way with respect to the inner peripheral wall surface of the cyclone container body 1. For example,
A zigzag shape may be used instead of the spiral shape. In the metal capillary,
A cooling medium such as water, brine, a refrigerant, or a heat storage agent is made to flow. The temperature of the cooling medium is set below the dew point temperature so as to condense the water vapor in the high temperature and high humidity air.

The high-temperature and high-humidity air that has flowed into the cyclone container body 1 comes into contact with the metal thin tubes of the cooling fluid flow passage 14 and is cooled by heat exchange, and the nuclear condensation of water vapor with the dust contained in the air as nuclei. Occurs and condensed water droplets are generated. The dust that causes the nuclear condensation is a fine particle, and therefore the fine dust is also captured. The condensed water droplets collide with the inner peripheral wall surface of the cyclone container body 1 by the centrifugal force of the swirling air flow. Further, the water vapor contained in the high-temperature and high-humidity air is condensed by the direct cooling due to the contact with the metal thin tube of the cooling fluid flow path 14 to be condensed water. The condensed water adsorbs and collects dust contained in the high temperature and high humidity air that swirls around. The dew condensation water is separated from the metal thin tubes by the swirling air flow, swirls together with the swirling air flow, and collides with the inner peripheral wall surface of the cyclone container body 1 by the centrifugal force thereof to form a liquid film. And
Embodiment 1 is applied to the liquid film thus formed.
The dust in the swirling airflow is taken in by the same operation as in the above case. The water that forms the liquid film flows down along the inner peripheral wall surface of the cyclone container body 1 due to gravity, and the dust-containing liquid discharge part 4
Is discharged from the system.

In the air circulation type clothes drying system using the cyclone type dust collector X of the second embodiment, the same effect as that of the first embodiment can be obtained. More specifically, the positive cooling further enhances the dehumidification efficiency and the dust collection performance, so that the apparatus can be further downsized.

[Embodiment 3] Embodiment 3 relates to an air-cycle type clothes drying system having a refrigeration cycle. FIG. 5 is a schematic configuration diagram of the air cycle type clothes drying system according to the third embodiment. In FIG.
Reference numeral X is a cyclone type dust collector, 20 is a flow rate adjusting means,
21 is a water storage tank, 22 is a drying action space (air-conditioned space)
As a drying drum, 23 as a compressor, 24 as an expansion turbine, 25 as a motor, 26 as a reheat type heat exchanger, and 27a, 2a.
7b is the first and second gas-liquid separators, indicated by solid arrows A
Is a drying cycle channel, and B shown by a broken line arrow is a liquid channel. The motor 23 in which the compressor 23 and the expansion turbine 24 are common
5 is driven. In the drying cycle flow path A, the outlet of the drying drum 22 is connected to the inlet of the cyclone type dust collector X, that is, the treated gas introduction part 3, and the outlet of the cyclone type dust collector X, that is, the clean gas discharge part 2 is connected. The compressor 23 is connected to the inlet of the compressor 23.
Of the reheat type heat exchanger 26 is connected to the inflow port of the reheat type heat exchanger 26, and the outflow port of the reheat type heat exchanger 26 is connected to the inflow port of the first gas-liquid separator 27a. The outlet of the vessel 27a is connected to the inlet of the expansion turbine 24, and the expansion turbine 2
4 is connected to the inlet of the second gas-liquid separator 27b, the outlet of the second gas-liquid separator 27b is connected to the other inlet of the reheat type heat exchanger 26, and Heat type heat exchanger 2
Another outlet of 6 is connected to the inlet of the drying drum 22. The compressor 23, the expansion turbine 24, the reheat type heat exchanger 26, the first gas-liquid separator 27a and the second gas-liquid separator 27b constitute a processing function section, and the processing function section and the drying action space. Is connected via a drying cycle flow path A, and the cyclone type dust collector X is interposed in the drying cycle flow path A. The gas to be processed which circulates in the drying cycle channel A is air. The liquid outlets of both gas-liquid separators 27a and 27b are connected to the inlet of the water storage tank 21 in the liquid flow path B, and the outlet of the water storage tank 21 communicates with the cyclone dust collector X via the flow rate adjusting means 20. Has been done.

As the cyclone type dust collector X, the one shown in FIG. 2 of the first embodiment or the one shown in FIG. 4 of the second embodiment is used.
The one having the configuration shown in is used.

Next, the operation of the air cycle type clothes drying system according to the third embodiment having the above-mentioned structure will be described.

The high temperature air heated up by the heat exchange in the reheat type heat exchanger 26 is guided to the drying drum 22, and the high temperature air comes into contact with the clothes stirred as the drying drum 22 rotates, Evaporate water from clothes,
Dry the clothes. The air containing water vapor becomes high temperature and high humidity air and is discharged from the drying drum 22.
Dust such as lint separated from clothes in the drying process is also contained in the high temperature and high humidity air and discharged from the drying drum 22 and guided to the cyclone type dust collector X. Cyclone dust collector X
The operation in will be described later. The high-temperature air flowing out from the cyclone type dust collector X is guided to the compressor 23, adiabatically compressed into high-temperature high-pressure air, and guided to the reheat type heat exchanger 26. In the reheat type heat exchanger 26, heat exchange between the high temperature and high pressure air from the compressor 23 and the low temperature and normal pressure air from the expansion turbine 24 is performed. The high temperature and high pressure air from the compressor 23 is cooled by this heat exchange to a temperature below the dew point temperature, and the water vapor contained therein condenses into water droplets.
The air containing the condensed water droplets is guided to the first gas-liquid separator 27a, and the condensed water droplets are removed. The separated condensed water droplets are guided to the water storage tank 21 by the liquid flow path B. The air from which the condensed water droplets have been removed is guided to the expansion turbine 24, becomes low temperature atmospheric pressure air, and is again below the dew point temperature, and the water vapor contained therein is condensed into water droplets. The air containing the condensed water droplets is guided to the second gas-liquid separator 27b, and the condensed water droplets are removed. The separated condensed water droplets are guided to the water storage tank 21 by the liquid flow path B. The air having condensed water droplets removed and having a sufficiently low humidity is guided to the reheat type heat exchanger 26, where it is heated up by heat exchange with the high-temperature high-pressure air from the compressor 23, and then to the drying drum 22. Is led.

First and second gas-liquid separators 27a, 27
The condensed water droplets separated in b are introduced into the water storage tank 21,
The water in the water storage tank 21 is guided to the cyclone type dust collector X in a state where the flow rate is adjusted by the flow rate adjusting means 20 and flows down while forming a liquid film on the inner peripheral wall surface of the cyclone container body 1. Then, high temperature and high humidity air containing dust from the drying drum 22 flows into the cyclone container body 1 from the to-be-treated gas introducing portion 3 which is tangentially connected to the cyclone container body 1 and swirls. The dust contained in the swirling air flow is adsorbed and collected by the liquid film, and is discharged from the dust-containing liquid discharge section 4 below to the outside of the system. The air cleaned in the cyclone dust collector X is discharged from the clean gas discharge part 2 and sent to the compressor 23. The other operations are the same as those in the first embodiment, and thus the description is omitted.

After the completion of the drying operation, the flow rate adjusting means 20 is operated to increase the flow rate and supply it into the cyclone type dust collector X, thereby causing a large amount of liquid to flow down to the inner peripheral wall surface of the cyclone container body 1, The inner peripheral wall surface can be washed.

As described above, since the condensed water or drain water obtained in the air cycle itself is used for the flowing liquid in the cyclone type dust collector X, the liquid is always replenished from the outside. The running cost can be reduced as compared with the case, and the piping system can be omitted.

By the way, the temperature of the air flowing out of the expansion turbine 24 is the lowest in the cycle. Therefore, the second gas-liquid separator 2 is separated from the air discharged from the expansion turbine 24.
If the capacity of the expansion turbine 24 is increased so that the amount supplied to the cyclone dust collector X can be covered only by collecting the condensed water droplets at 7b, the first gas on the inlet side of the expansion turbine 24 can be provided. The liquid separator 27a can be omitted.

Further, in the refrigeration cycle of the air cycle system, it is well known that a cold heat source can be obtained by the cycle itself, but the cold heat source is used as a means for cooling the swirling air flow in the cyclone container body 1. It is also possible.

The above can be summed up as follows. By installing the cyclone type dust collector X,
Litter and other fine dust are almost 1 without re-scattering
It is possible to collect 00%. That is, a dramatic improvement in dust collection capability can be observed without increasing pressure loss. Furthermore, since the inside of the cyclone type dust collector X can be washed with running water from above, maintenance can be performed maintenance-free or simplified.

In the air-cycle type clothes drying system using the refrigeration cycle shown in FIG. 5, the cyclone type dust collector X having the structure shown in FIG. 2 of the first embodiment is used as the cyclone type dust collector X. . In this case, the following phenomenon occurs in the cyclone dust collector X. The swirling high-temperature and high-humidity air and the flowing-down liquid are in direct contact with each other to exchange heat with each other, and the water vapor contained in the swirling high-temperature and high-humidity air is condensed to form water droplets. The air is cooled by heat exchange and the humidity is lowered by the condensation of water vapor. In a swirling air flow containing water droplets, condensed water adsorbs and collects fine dust. Further, the falling liquid adsorbs and collects both fine dust and large dust. The dust and water droplets contained in the swirling air collide with the inner peripheral wall surface of the cyclone container body 1 by the centrifugal separation effect. A part of the flowing-down liquid also collides with the inner peripheral wall surface of the cyclone container body 1 due to the centrifugal force and flows down the inner peripheral wall surface. On the inner peripheral wall surface of the cyclone container body 1, dust and water droplets in the swirling air flow are absorbed by the flowing liquid, and along with the liquid, they are transmitted from the dust-containing liquid discharge part 4 along the inner peripheral wall surface of the cyclone container body 1. It is discharged out of the system of the cycle flow path A.

As described above, the high-temperature and high-humidity air containing dust introduced from the drying drum 22 is removed from the water vapor, thread waste and other fine dust, and clean low-humidity air is discharged from the clean gas discharge section 2. It is discharged and sent to the compressor 23.

After the completion of the drying operation, the flow rate adjusting means 2 is operated to increase the flow rate and supply it into the cyclone type dust collector X, thereby causing a large amount of liquid to flow down to the inner peripheral wall surface of the cyclone container body 1. The inner peripheral wall surface of the cyclone container body 1 can be washed.

When the air containing cotton dust is introduced into the cyclone type dust collector at a flow rate of 1 m ³ / min, the cyclone type dust collector is designed so that the minimum particle size of the cotton dust that can be completely separated is about 10 μm. X was designed. Cyclone dust collector X
Is a type that connects to a pipe diameter of 30 mm and has a total height of 280
mm. When the relationship between the flow rate of high-temperature and high-humidity air, the minimum particle size of cotton dust that can be collected, and the pressure loss in the prototype was examined, it was as shown in FIG. The characteristic of the minimum cotton particle size is shown by a broken line, and the pressure loss is shown by a solid line. The minimum particle size of cotton dust that can be completely separated when the flow rate of air is 1 m ³ / min is about 10 μm, and the pressure loss at that time is about 2300 Pa (Pascal).

Therefore, the collection ability of the cyclone type dust collector and the collection ability of the filtration type filter were compared. As the filtration filter, the highest-performance filter PS600 that can be recycled by washing with water was used. As for the filtration type filter, the collection capacity was about 80% for particles of 10 μm, and it was impossible to collect 100% of particles of 10 μm. On the other hand, according to the cyclone type dust collector, 100% of particles of 10 μm can be collected.

The relationship between the amount of dust collected and the pressure loss in the case of the third embodiment using the cyclone type dust collector X is shown by a broken line in FIG. The characteristic of the filter is shown by a solid line. The filtration type filter has a pipe diameter of 50 mm. In the case of a filtration type filter, the pressure loss increases as the trapped amount increases. On the other hand, in the case of the cyclone dust collector X, it was found that the pressure loss was kept constant regardless of the increase in the amount of trapped particles.

In addition, the pressure loss of the filtration type filter is smaller in the initial state where the collection amount is 6 g or less, but it is assumed that the collection rate of particles of 10 μm is about 80%. It ’s just that. If a filtration type filter having a collection rate of 100% is used as in the cyclone type dust collector X, it is assumed that the initial pressure loss is larger than that in the state of FIG. 7 due to the finer mesh. .

From the above-mentioned circumstances, it can be said that the cyclone type dust collector is superior in both the collecting ability and the pressure loss in total.

The above can be summed up as follows. By installing the cyclone type dust collector X,
100 pieces of lint and other fine dust are not scattered
It becomes possible to collect%. That is, a dramatic improvement in dust collection capability is recognized. Furthermore, since the inside of the cyclone type dust collector X can be washed with the liquid flowing down from above, maintenance can be performed maintenance-free or simplified.

In the air cycle type clothes drying system according to the third embodiment, as described in the first embodiment with reference to FIG. 3A, the high temperature and high humidity air flowing in the cyclone type dust collector X is used. Since the cooling fluid is swirling, the cooling fluid is caused to flow into contact with it, so even if the cooling fluid is made to flow linearly, the contact area between the swirling high temperature and high humidity air and the cooling fluid becomes large, Exchange efficiency is increased and gas-liquid separation action is improved. At the same time, the dust collecting ability is also improved. Since the dust removing portion and the gas-liquid separating portion are the same portion, it is possible to downsize the device.

[Embodiment 4] Embodiment 4 relates to an air-cycle type air conditioner system. FIG. 8 is a schematic configuration diagram of the air-cycle type air conditioner system according to the fourth embodiment. In FIG. 8, reference numeral X indicates a cyclone type dust collector, 31 indicates an air-conditioned space as a treated space, 32 indicates a compressor, 33 indicates an expansion turbine, 34 indicates a motor, 35 indicates a heat exchanger, 36 indicates a fan, and C Is an air conditioning cycle flow path.
The compressor 32 and the expansion turbine 33 are driven by a common motor 34. The fan 36 blows cooling air to the heat exchanger 35. In the air conditioning cycle flow path C, the outlet of the air-conditioned space 31 is connected to the inlet of the cyclone dust collector X, the outlet of the cyclone dust collector X is connected to the inlet of the compressor 32, and the compressor The outlet of 32 is connected to the inlet of the heat exchanger 35, the outlet of the heat exchanger 35 is connected to the inlet of the expansion turbine 33, and the outlet of the expansion turbine 33 is connected to the inlet of the air-conditioned space 31. Has been done. Air conditioning cycle channel C
At the end of the air-conveying pipe extended from the outlet of the air-conditioned space 31, the treated gas introducing portion 3 of the cyclone type dust collector X is connected, and extended from the inlet of the compressor 32. The clean gas discharge part 2 of the cyclone type dust collector X is connected to the end of the air carrying pipe. The compressor 32, the heat exchanger 35, and the expansion turbine 33 constitute a processing function unit, and the processing function unit and the air-conditioned space 31 form an air conditioning cycle flow path C.
A cyclone type dust collector X is installed in the air conditioning cycle flow path C. The gas to be processed which circulates in the air conditioning cycle flow path C is air.

As the cyclone type dust collector X, the one shown in FIG. 2 of the first embodiment or the one shown in FIG. 4 of the second embodiment is used.
The one having the configuration shown in is used.

Next, the operation of the air-cycle type air conditioner system of the fourth embodiment having the above configuration will be described.

Air-conditioning air containing dust discharged from the air-conditioned space 31 is guided to the cyclone type dust collector X, where it is dust-removed into clean air and sent to the compressor 32. Compressor 32
Is compressed into high-temperature high-pressure air in the heat exchanger 35.
Is cooled in the air conditioner, and further expanded in the expansion turbine 33 to become low temperature atmospheric pressure air, which is supplied to the air-conditioned space 31.

In the cyclone type dust collector X, the air-conditioning air that has flowed into the cyclone container body 1 from the air-conditioned space 31 through the gas-to-be-treated introduction portion 3 swirls and is included in the swirling air flow by the centrifugal action. The dust that has collided collides with the inner peripheral wall surface of the cyclone container body 1, flows down the inner peripheral wall surface by its own weight, and is discharged to the outside of the air conditioning cycle flow path C. In the case of a filtration type filter, dust is collected by the filter itself set in the air conditioning cycle flow path C and stops there, so that dust accumulates and requires maintenance. On the other hand, in the case of the fourth embodiment, since the dust is discharged to the outside of the system of the air conditioning cycle flow path C, the dust is not accumulated and the maintenance becomes easy.

As described above, since the cyclone type dust collector X has a lower pressure loss than the filtration type filter, the driving force necessary for circulating the air for air conditioning is reduced and the running cost is reduced.

If the liquid is made to flow down to the inner peripheral wall surface of the cyclone container body 1, the inner peripheral wall surface of the cyclone container body 1 can be washed by the flowing liquid, and maintenance-free can be realized. In addition, when the liquid has a low temperature, it has a dehumidifying action.

In the fifth embodiment as well, similar to the fourth embodiment, the maintenance is easy and the running cost can be reduced. In addition, maintenance free can be realized by the liquid flowing down.

Next, a cyclone type dust collector Y provided with two to-be-treated gas introducing portions and the cyclone type dust collector Y
An air-cycle type clothes drying system and an air-cycle type air-conditioning system using the above will be described.

[Sixth Embodiment] FIG. 10 is a schematic configuration diagram of a cyclone dust collector Y. Cyclone dust collector Y is
The upper right cylindrical portion 61a and the lower lower conical cylindrical portion 6
Cyclone container body (outer cylinder) 61 with a lid and comprising 1b
And a clean gas discharge portion (inner cylinder) 62 that is concentrically arranged in the upper part of the central portion in the cyclone container body 61 and extends upward through the top plate portion of the body 61, First and second treated gas introduction portions (feed cylinders) that communicate with each other in the tangential direction at the upper portion of the cyclone container body 61
63a and 63b, and a dust-containing liquid discharge part 64 formed at the lower end of the cyclone container body 61. The inner peripheral wall surfaces of the right cylinder portion 61a and the conical cylinder portion 61b of the cyclone container body 61 are made smooth so as not to hinder the smooth swirling of the air flow inside the cyclone container body 61.

The first gas-to-be-treated introduction portion 63a and the second gas-to-be-treated introduction portion 63b are connected to each other on the peripheral surface of the upper end portion of the cyclone container body 61 with a vertical gap. It is assumed that high temperature and high humidity air is introduced into the upper first gas to be treated introduction portion 63a and low temperature and high humidity air is introduced into the second lower treatment gas introduction portion 63b. In addition, although the 1st to-be-processed gas introducing | transducing part 63a and the 2nd to-be-processed gas introducing | transducing part 63b are provided in the same position of the circumferential direction of the cyclone container main body 61, it is shown, but it is necessary to limit to this. Alternatively, they may be provided at different positions in the circumferential direction. However, it is necessary that the direction of the swirling flow of the high temperature and high humidity air is the same as that of the low temperature and high humidity air. However, it does not prevent the swirling flow in the opposite direction.

First treated gas introducing portion 63a and second
In the case of the cyclone type dust collector Y having the treated gas introducing portion 63b, the high temperature and high humidity air containing dust having a density lower than that of water droplets is introduced into the cyclone container body 61 from the upper first treated gas introducing portion 63a. On the other hand, the low-temperature and high-humidity air that does not contain dust is introduced into the cyclone container main body 61 from the second lower gas to be treated introducing portion 63b. The solid line in FIG. 11 shows the flow of high temperature and high humidity air, and the broken line shows the flow of low temperature and high humidity air. By swirling in the same direction and contact mixing, dust and water droplets generated by nuclear condensation are collected and dust is collected. The clean air discharged from the contained liquid discharge part 64 is sent to the outside from the clean gas discharge part 62.

Here, there are two types of high temperature and high humidity air and low temperature and high humidity air.
When the fluid swirls in the cyclone container body 61, the number of rotations is the height a from the dust-containing liquid discharge portion 64 to the first treated gas introduction portion 63a shown in FIG. It is determined by b up to the second treated gas introducing portion 63b. In order to collect dust and water droplets contained in the air, both dust and water droplets need to collide with the inner peripheral wall surface of the cyclone container body 61 while the air is swirling. However, dust is less dense than water droplets. Therefore, dust having a density lower than that of water drops needs to rotate more times than water drops. For that purpose, the cyclone height a is required to be higher for the hot and humid air containing dust. For example, in the cyclone container main body 61 having a diameter of 70 mm, the size of the gas introduction portion to be treated is 17.5 mm in length and 3 in width.
In the case of a 5 mm cyclone dust collector, when 1 m ³ / min of gas is introduced into the cyclone container body, it takes 5 rotations to collect cotton dust and 0.4 rotations to collect water droplets. It has been confirmed.

For this reason, the first gas-to-be-treated introduction portion 63a for introducing the high temperature and high humidity air containing dust is arranged at the upper level, and the first low temperature and high humidity air containing no dust is introduced. The second gas-to-be-treated introducing portion 63b is arranged in the lower order. In other words, the high temperature and high humidity air that contains low-density dust and high-density water droplets is rotated more,
The low-temperature and high-humidity air that contains high-density water droplets but does not contain low-density dust is rotated at a low number of rotations to simultaneously remove dust and gas-liquid.

Here, a comparison with the prior art will be described for reference. In the case of Japanese Utility Model Laid-Open No. 5-88645, on the contrary to the above, since the introduction part of the high temperature and high humidity air is arranged in the lower order and the introduction part of the low temperature and high humidity air is arranged in the higher order, the lower introduction part. In order for the dust contained in the high temperature and high humidity air introduced from the above to be favorably collected by the centrifugal separation, the cyclone container body becomes large in size in order to secure the number of rotations. On the other hand, in the sixth embodiment,
Since the high-temperature and high-humidity air containing dust is introduced from the upper first gas-to-be-treated introduction portion 63a, it is possible to reduce the height of the cyclone container main body 61 by ensuring the same number of rotations, and to reduce the entire equipment. It can be miniaturized.

To be done. Further, the air flowing out from the expansion turbine 74 is clean low-temperature high-humidity air containing no dust, and this low-temperature high-humidity air is a lower second gas to be treated introduction portion with respect to the cyclone dust collector Y. It is introduced into the cyclone container body 61 from 63b.

The condensed water can collect dust in the vicinity, and can also collide with the inner peripheral wall surface of the cyclone container main body 61 by the centrifugal force due to the swirling, and collect dust on the inner peripheral wall surface. The condensed water containing dust flows down along the inner peripheral wall surface and is discharged from the dust-containing liquid discharge portion 64. At this time, it is desirable to use the condensed water collected by the gas-liquid separator 77 as the insufficient water. When the cyclone dust collector Y has sufficient gas-liquid separation capability, the gas-liquid separator 77 can be omitted.

As described above, in the air-cycle type air conditioner system according to the seventh embodiment, the dust is collected in the cyclone container body 61 without being scattered again, and the dust collecting ability is improved. Moreover, since the inner peripheral wall surface of the cyclone container body 61 is purified by running water,

It is possible to downsize the equipment of the air cycle type clothes drying system.

In particular, the first treated gas introducing portion 63a for introducing high temperature and high humidity air containing dust is arranged in the upper layer,

By rotating more and more high-temperature and high-humidity air containing air, the dust collection capability and the gas-liquid separation function are improved.
