BACKGROUND OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a separator for making a room with various heat loads into a clean room having a comfortable room temperature, and an indoor air conditioner using the separator, and more particularly a triple cyclone that can be compactly packed and can introduce fresh air. It relates to a type separator.
[0002]
[Prior art]
In general, various heat loads (cooling loads) are generated in a room in a building. For example, as heat load, heat transmitted from various heat generation sources, intrusion heat from outside air, heat generated from residents, ventilation heat, heat generated from power and lamps, etc., from various objects entering and exiting the room There are various things such as heat. Therefore, the interior of a building often has a higher temperature than the outside air. In addition, a comfortable living temperature for human beings is about 23 ° C., but it is generally difficult to keep the room at this temperature without using any ventilation or cooling / heating device.
[0003]
As shown in FIG. 6, if the space in the room 31 is divided into two spaces, a lower space (indicated by A) where humans live and an upper space (indicated by B) above this space, (B) generally has a higher temperature than space (A). However, in order to make the interior of the room 31 comfortable, it is necessary to always ventilate the entire interior space so that it is first equal to the outside temperature, and to make it comfortable. In general, a building is provided with an outside air introduction port 38 and an exhaust port 33 as a means for ventilating the room 31, and the outside air enters from the outside air introduction port 38 and expels the room air from the exhaust port 33. In this case, if all the room air can be expelled, the room 31 is ventilated. However, since foreign air and foreign substances are generally mixed in the outside air, a filter 39 is generally provided at the outside air inlet 38 in order to remove this. However, since the filter 39 is a flat body and the inside of the chamber 31 is a three-dimensional body, it is difficult to keep the ventilation in the chamber 31 by the outside air clean by blocking the filter 39 or the like.
[0004]
[Problems to be solved by the invention]
Therefore, as shown in FIG. 7, a cyclone separator that can introduce a large amount of air is generally employed on the outside air inlet 38 side. There are various types of cyclonic separators, for example, those disclosed in Japanese Patent Application Laid-Open No. 10-192739 are common. This has a structure like the cyclonic separator 1a shown in FIG. 7, and its air introduction part 41 is introduced from one tangential direction to the main body 40 of the cyclonic separator as shown in FIG. Most of the formats are.
[0005]
In the case of the cyclonic separator 1a and the like having the above structure, air introduced into the cyclonic separator 1a is subjected to various resistances and depressurized, and in this state, a vortex is generated in the tapered main body 40. Separation of air from foreign matter and the like is performed. For this reason, in the conventional cyclone separator 1a, the efficiency of separating and removing foreign substances and harmful substances in the air is poor, and the removal of fine particles becomes insufficient, and a plurality of filters are required for this removal. For this reason, the filter is clogged, and it is sometimes necessary to replace or clog the clogging, which is extremely inefficient.
[0006]
On the other hand, as described above, the inside of the room 31 needs to be completely ventilated by the outside air and kept in a clean room. Well, the space (B) where the generated heat rises and remains is only required to be ventilated with the outside air and does not need to be at a comfortable temperature. However, the conventional technology employs a cooling / heating device having a capacity to bring the space (A) and the space (B) to a comfortable temperature, and particularly requires a large amount of cooling power consumption.
[0007]
The present invention has been invented in view of the above circumstances, and can completely ventilate the air in the space and keep the space as a clean room, and keeps only the space where people mainly live at a comfortable temperature. An object of the present invention is to provide a triple cyclone separator that saves power consumption and performs efficient air conditioning.
[0008]

It consists of a cylinder which forms an opening. In addition, the removal lid 8 required in order to perform this replacement | exchange and a maintenance is detachably attached to the outer surface of the hollow outer cylinder 2 in the vicinity of the second-stage cyclone separator 4 disposed.
[0011]
The first-stage cyclone separator 3 has a shape similar to that of a conventionally employed cyclone separator, and is connected to the lower side of the outside air introduction portion 9 into which outside air is introduced and is reduced in diameter downward. It has what has the discharge part 11 etc. which are formed in the upper part of the taper tube 10 and the external air introduction part 9 which do. An opening / closing valve 12 is provided at the lower end of the taper tube 10 for discharging separated foreign substances and harmful substances (hereinafter referred to as dust).
[0012]
As shown in FIG. 2, the outside air introduction portion 9 includes a plurality of (four in the drawing) introduction portions 14 that are formed at equal positions along the circumferential direction. The As shown in the drawing, the introduction path 15 communicating with the introduction portion 14 is formed to curve substantially along the circumference, and a jet outlet 16 communicating with the tapered tube 10 is formed at the tip thereof. The introduction portion 14 and the introduction path 15 are partitioned by an outside air introduction guide plate 13. In addition, a mesh wire net 17 for removing foreign substances is provided in the introduction portion 14. With the structure described above, the outside air introduced from the respective introduction portions 14 of the outside air introduction portion 9 is ejected from the ejection port 16 into the tapered tube 10 through the introduction path 15 after the foreign matter is removed by the mesh metal mesh 17. Not only one place but also four uniform outlets 16 eliminate the pressure attenuation at one place as in the conventional cyclone separator, and an efficient cyclone motion is generated in the taper tube 10. On the other hand, the taper tube 10 is composed of a taper member whose diameter is reduced toward the lower portion as described above, and is configured to perform a cyclonic motion therein. The second-stage cyclone separator 4 to be described next includes a rotating body separator. The first-stage cyclone separator 3 includes the negative pressure side of the second-stage cyclone separator 4 and the outside air pressure. The feature is that it operates by the difference between the two and does not use a rotating gravity body.
[0013]
Next, the structure of the second stage cyclonic separator will be described with reference to FIGS. As shown in FIG. 1, the second-stage cyclone separator 4 is composed of a pair of elements disposed on the left and right objects at an upper part of the first-stage cyclone separator 3 and inclined inward. As shown in FIG. 1, the air intakes 18 and 18 are arranged in communication with the discharge part 11 of the first-stage cyclone separator 3. As shown in FIG. 3, the second-stage cyclone separator 4 includes a case body 19, an external cyclone unit 20 accommodated therein, an internal cyclone unit 21 accommodated therein, and the like. Is done.
[0014]
The case body 19 is formed of a hollow cylinder, and a discharge port 22 is formed in the upper part, and an opening / closing valve 23 is provided in the lower part. On the other hand, the outer cyclone portion 20 is composed of an upper cylinder 24 and a trumpet tubular cylinder 25 which is inserted into the upper cylinder 24 and expands downwardly in a tapered shape. The upper cylinder 24 is provided with a fine filter 26. The internal cyclone portion 21 is composed of a tapered cylindrical tube 27 whose diameter increases upward, and the upper opening portion communicates with the discharge port 22.
[0015]
When air is introduced into the case main body 19 from the air intake 18 of the second-stage cyclonic separator 4 having the above structure, the air is relatively large in the fine dust while winding around the external cyclone portion 20. The dust 28 is removed. The dust 28 descends along the outer surface of the trumpet tubular cylinder 25, accumulates on the on-off valve 23 side, and is removed by opening the on-off valve 23. On the other hand, the air that has passed through the filter 26 of the external cyclone unit 20 is spirally wound, performs a cyclonic motion in the tapered cylindrical tube 27, pushes out the fine particles 29 downward, and sends the purified air upward. The purified air is discharged from the discharge port 22. On the other hand, the particles 29 accumulate below the tapered cylindrical tube 27 and are discharged when the on-off valve 23 is opened.
[0016]
Next, the operation of the triple cyclone separator 1 will be described. Insects and dust are removed from the outside air (air) introduced from the introduction port 6 of the hollow outer cylinder 2 by the mesh wire mesh 17, and the inside from the four introduction parts 14 of the outside air introduction part 9 of the first-stage cyclone separator 3 Enters, passes through the introduction path 15, and is ejected from the ejection port 16 into the taper tube 10 to perform a cyclonic motion. As a result, dust, dust, and the like are further removed and relatively cleaned air is ejected from the upper discharge portion 11. On the other hand, the removed dust, dust or the like is accumulated below the tapered tube 10 and is removed by opening the on-off valve 12.
[0017]
The relatively purified air ejected from the discharge part 11 enters the case body 19 from the air intakes 18 and 18 of the respective second-stage cyclone separators 4 and 4, and enters the external cyclone part 20 and the internal cyclone. Dust 28 and particles 29 are removed by the part 21 and the purified air is moved upward while moving in a cyclone motion, proceeds from the discharge port 22 toward the blowout port 7, and is connected to the blowout port 7. From FIG. 4).
[0018]
Next, an indoor air conditioner 100 using the triple cyclone separator 1 having the above structure will be described with reference to FIG. As described above, the room 31 of the building 32 where the thermal load is generated is divided into a space (A) where a human lives and a space (B) above it. The heat due to the heat load rises and accumulates on the space (B) side. The triple cyclone separator 1 is installed upright near one side of the outside of the chamber 31, and a fresh air intake pipe 30 connected to the outlet 7 is inserted into the chamber 31. In the case of the present embodiment, the fresh air intake pipe 30 is piped along the horizontal direction and inserted into the space (B). On the other hand, an exhaust port 33 is formed in the other side surface of the chamber 31 at a position substantially opposite to the fresh air intake pipe 30. An exhaust fan 34 may be provided in the exhaust port 33. In addition, a heat pump 35 is provided in a space (A) where a person or the like lives. For example, the heat pump 35 has a structure in which cold air is discharged from the outlet 36 into the space (A) and heat exchange with the space (A) is performed, and then the return of the cold air is introduced into the heat pump 35 from the inlet 37. Thus, by making the exhaust capacity of the triple cyclone separator 1 ventilate the entire chamber 31, the inside of the chamber 31 becomes substantially equal to the outside air temperature, and air is supplied from the triple cyclone separator 1. The air in the chamber 31 is discharged from the exhaust port 33 to the outside air side by the fresh air.
[0019]
When the season is summer, the outside air temperature outside the building 32 is about 35 ° C., for example. Therefore, when this outside air is introduced into the chamber 31, the air itself is fresh, but the temperature in the chamber 31 is close to 35 ° C. There is no particular problem if the space (B) where humans do not live is filled with fresh air even if it reaches 35 ° C, but it cannot be said that the space (A) is a comfortable space at 35 ° C. . Since the temperature of the comfortable space is about 23 ° C., the temperature should be lowered by 35 ° C.−23 ° C. = 12 ° C. in order to create a comfortable space. Therefore, the heat pump 35 only needs to exchange heat at 12 ° C., and may have a smaller capacity than the conventional case where both the spaces (B) and (A) are held at 23 ° C. Reduction and power saving effect. Since the heat generated in the chamber is excluded by the cyclone external air and is not considered as a load on the refrigerator, the load on the refrigerator may be small.
[0020]
On the other hand, if the outside air temperature is about 5 ° C. in winter, the temperature of fresh air introduced from the triple cyclone separator 1 into the chamber 31 is about 5 ° C. In this case, the space (A) only needs a heat pump 35 having a capacity for heating the space (A) by 23 ° C.−5 ° C. = 18 ° C. As described above, according to the present invention, clean air is sent into the chamber 31 and complete ventilation is performed to form a clean room. At the same time, equipment costs can be reduced and significant power savings can be achieved. . If there is heat generated in the room, it is used for heating. In addition, a heat pump that uses exhaust heat that uses generated heat as a heat source is provided in the air exhaust unit. FIG. 4 shows an example in which an exhaust heat recovery heat pump 45 is provided.
[0021]
Next, an indoor air conditioner 100a using the triple cyclone separator 1 of the present invention will be described with reference to FIG. In this case, as shown in the figure, the fresh air intake pipe 30 connected to the outlet 7 of the triple cyclone separator 1 extends horizontally in the chamber 31 to form a downward outlet 42 in the middle thereof and a heat pipe. A heat exchanger 43 is connected. A duct 44 communicating with the space (B) side of the chamber 31 is connected to the heat pipe heat exchanger 43. The duct 44 includes an inlet 45 communicating with the space (B) and an outlet 46 communicating with the atmosphere. A filter 47 is provided at the inlet 45. By adopting the above heat pipe heat exchanger 43, the heat in the chamber 31 can be used, and fresh air introduced from the triple cyclone separator 1 into the chamber 31 is heated without any special heat supply. In particular, power saving of the heat pump 35 in the space (A) in winter can be achieved.
[0022]
