[0003]

In a conventional cooling device, water, ammonia, or the like is used as a substance to be attached to an adsorbent. For this reason, it is difficult to maintain the fluidity of the adsorption medium in order to lower the temperature of the liquid such as water. Furthermore, when desorbing from the adsorbent, the pressure is reduced by a compressor or the like, or pressure is applied for liquefaction, so that the energy efficiency is low. It is difficult to reuse the desiccant in the technology of heating the gas by passing the gas through the desiccant.

It is a schematic diagram showing a process.

Referring to FIG. 1, the overall configuration of the water treatment apparatus will be described. In this embodiment, the water treatment apparatus 1 purifies sewage such as a river. The water treatment device 41 includes a primary treatment unit 42, a secondary treatment unit 43, a tertiary treatment unit 44, a flow rate measurement unit 45, and an ozone treatment unit 49. The water to be treated introduced into the primary treatment section 42 is subjected to separation and removal of solids, fine suspended matter, fats and oils, etc.
Sent to 3. In the water to be treated introduced into the secondary treatment section 43, organic substances contained by microorganisms are decomposed and stabilized. The water to be treated introduced into the tertiary treatment section 44 is added with a coagulant or the like, and a substance such as phosphorus is coagulated and precipitated to be removed.

The water treated in the tertiary treatment section 44 is
It is introduced into the flow rate measuring unit 45, and the flow rate measuring unit 45 measures the amount of the water to be treated. Then, a catalyst for promoting oxidative decomposition is added to the water to be treated in accordance with the amount of the water to be treated. That is, the flow rate measuring unit 45 measures the amount of water and adds the catalyst. The catalyst is added and the water to be treated is thereafter introduced into the ozonation unit 49,
Ozone is diffused into the water to be treated, and the water to be treated is purified by the ozone. As described above, since an appropriate amount of catalyst is added in the flow rate measuring section 5 and ozone treatment is performed, the ozone treatment power can be sufficiently exhibited, and the purification efficiency of ozone can be improved.

In the above configuration, a water quality inspection device is connected downstream of the flow rate measuring unit 45 and the ozone processing unit 49, and can recognize the amount of the water to be processed and detect the water to be processed after the ozone processing. It has a configuration. Flow measurement unit 45
In, the flow rate of the water to be treated is recognized, and the detected value of the flow rate of the water to be treated is output to the water quality inspection device. Further, in the ozone treatment section 49, the water subjected to the ozone treatment is collected downstream of the ozone treatment section 49 and introduced into the water quality detection device, where the water quality is inspected.

Next, the ozone storage device 46 of the present invention will be described. The ozone storage device 46 is the water treatment device 41
For storing ozone for supplying ozone to the reaction tank of the ozone processing section 49 of FIG. In the ozone storage device 46, oxygen is introduced into the ozonizer 48. Here, as the oxygen supply source 47 for supplying oxygen to the ozonizer 48, an oxygen cylinder and a liquid oxygen device can be used. Ozone generated by the ozonizer 48 is supplied to the storage device 46 via an ozone monitor and a flow meter. The storage device 46 is filled with silica gel. The ozone discharged from the storage facility 46 is configured to be introduced into the reaction tank of the ozone processing unit 49, and the concentration of the remaining ozone discharged from the reaction tank is monitored by an ozone monitor.

Ozone from the ozone monitor is decomposed and made harmless by an ozone decomposer and discharged to the outside. The ozonizer 48 is controlled by a control device. That is, the ozone generated by the ozonizer 46 is stored in the storage facility 46 and supplied to the ozone processing unit 49. Then, in the ozone treatment section 49, water treatment is performed. The storage device 46 stores ozone mainly generated using midnight power. Then, water is purified using the stored ozone during the daytime, when the amount of treated water such as domestic water is large.

Referring to FIG. 2, the process of adsorbing and releasing ozone will be described. FIG. 2A shows a storage device in the adsorption process, and FIG. 2B shows a storage device in the release process. In FIG. 2A, ozone generated by the ozonizer is introduced into the storage device 46. When ozone is adsorbed on the adsorbent, it generates heat. At this time, FIG.
As shown in (a), the heat exchanger 50 is disposed in the storage device, and a medium cooler than the adsorbent is circulated through the heat exchanger 50, thereby removing the heat at the time of adsorbing ozone and smoothing the adsorption. It can be carried out. The medium circulating in the heat exchanger 50 is heated by absorbing heat from a cold state by being introduced into the storage device 46.

In FIG. 2B, the ozone adsorbed on the adsorbent of the storage device 46 is released from the adsorbent by supplying oxygen into the storage device 46. Ozone absorbs heat as it is released from the adsorbent. At this time, FIG.
As shown in (b), by arranging the heat exchanger 50 in the storage device and circulating the heat transfer medium through the heat exchanger 50, the flow of heat at the time of ozone release is made smooth, and the release of ozone is further improved. It can be done smoothly. And the heat exchanger 5
The medium circulating in the space 0 is cooled by being introduced into the storage device 46. Ozone can be easily released by supplying oxygen. In the adsorption process, oxygen coexists with ozone. In this case, however, the oxygen concentration is low, and properties such as the concentration and the excited state are different from those of oxygen directly supplied from the oxygen supply source.

As described above, cooling can be performed by releasing the ozone once stored. In addition, the stored ozone can be easily released by supplying oxygen. When ozone is released, heat is absorbed. For this reason, a cooling device utilizing adsorption and release of ozone can be configured with an easy configuration. This cooling device can perform cooling in a temperature range where ozone can exist as a gas, and can easily perform cooling at extremely low temperatures.

Next, the state when ozone is adsorbed on the adsorbent and released from the adsorbent will be described with reference to FIG. In this embodiment, silica gel is used as the adsorbent. The ozone is occluded or adsorbed by the silica gel, whereby the ozone is clathrated or associated in the silica gel. (In the present description, adsorption is used below as including occlusion.) Then, these clathrated or associated ozone is easily purged by supplying oxygen to the silica gel, and the ozone is released from the silica gel. (Desorption). Further, the above-mentioned steps are performed at a pressure of about 1-2 at atmospheric pressure.
It can be performed under atmospheric pressure. The inventor considers that the mechanism of adsorption and desorption in this embodiment is based on the following mechanism. FIG. 3A shows the ozone adsorption state, and FIG. 3B shows the ozone release state. It is already known that ozone can easily assume a polarized state stably, and it is thought that a plurality of ozone molecules associate in the pores when the polarized ozone is introduced into the pores of the silica gel. Can be The polarized ozone molecules are adsorbed on the surface of the silica gel by Coulomb force, and the polarized state is stably maintained.
Then, another ozone is associated with the ozone stabilized in the polarization state. Accordingly, it is considered that ozone is likely to stably take a state shown in FIG. 3A in pores having a negatively charged surface such as silica gel.

[0015] The clathrated ozone loses its balance due to the supply of oxygen and cannot be sufficiently stabilized in the silica gel.
Is discharged. Therefore, as shown in FIG. 3B, the ozone that has been stably present on the surface of the silica gel is destabilized by the supply of oxygen, and is discharged from the silica gel. Ozone discharged from silica gel has properties such as easy dissolution in water, so ozone that has collapsed from the clathrate state does not behave as a single molecule at all, but multiple molecules are associated or approached by electrostatic force and stable. It is considered that the molecule is released in a state of being converted and in a state where a plurality of molecules are bound. Thereby, it is considered that the ozone via the silica gel is modified to increase the solubility in water and to improve the oxidative decomposition power. As mentioned above, ozone is easily adsorbed on silica gel,
It is easily released from the adsorbent by the supply of oxygen. Moreover, ozone is released by absorbing heat when released from the adsorbent.

According to the present invention, in the above-described process, after ozone is adsorbed or occluded on silica gel, cooling is performed by using latent heat generated when the ozone is released from silica gel. Ozone is used to generate and store ozone in the middle of the night when power demand is low, such as when performing water purification treatment of sewage, etc.
When used in the daytime, it is also possible to utilize the flow of heat generated by adsorption and desorption of ozone to an adsorbent such as silica gel. Then, it is also possible to introduce ozone into a circulation path that repeatedly adsorbs and releases ozone generated at midnight until it is used during daytime, and cools the ozone.

Next, the configuration of the cooling device 1 utilizing the adsorption and release of ozone to the adsorbent will be described. FIG.

・ 22 ・ 23 ・ 24 are provided. The three-way valves 21 and 24 and the three-way valves 22 and 23 are connected by piping, and the three-way valve is configured to be able to change the circuit in which oxygen and ozone circulate.

Furthermore, the three-way valve 25
26, 27 and 28 are connected. By switching the three-way valves 25, 26, 27 and 28, the heat exchanger 6.
The medium flowing into 7 can be switched from cooling to heating or from heating to cooling. Pipes 32 and 34 are connected to the three-way valve 25, and pipes 31 and 33 are connected to the three-way valve 26. A medium for heating is sealed in the pipes 31 and 32, and a medium for cooling is sealed in the pipes 33 and 34. Therefore, by connecting the pipes 31 and 32 to the heat exchanger 6 by the three-way valves 26 and 25, a heating medium can be circulated through the heat exchanger 6. Also,
Similarly, the pipes 33 and 34 are connected to the heat exchanger 6,
A cooling medium can be circulated.

The cooling process of the ozone cooling device will be described with reference to FIGS. FIG. 5A shows a process in which ozone is adsorbed by the adsorbent unit 4, and FIG. 5B shows a state in which ozone is sufficiently adsorbed by the adsorbent unit 4. FIG. 6C shows a process in which ozone is adsorbed by the adsorbent unit 5 and ozone is released from the adsorbent unit 4.
(D) shows that ozone is sufficiently adsorbed by the adsorbent unit 5,
This shows a state in which ozone has been sufficiently released from the adsorbent unit 4. (In the figure, the dot portions given to the adsorbent units 4 and 5 schematically show the ozone adsorption state.) First, the process of adsorbing ozone to the adsorbent unit 4 will be described. Three-way valve 21 ・ 22 ・ 2
As shown in FIG. 5A, the path of the pipe is constituted by 3.24. This piping configuration has three-way valves 21, 22 and 23.
· It is configured by switching of 24. The ozonizer 3 is connected to the adsorbent unit 4 by a pipe connecting the three-way valves 21 and 22, and the gas discharge side of the adsorbent unit 4 is connected to the adsorbent unit 5 by a pipe.
The gas discharge side of the adsorbent unit 5 is a three-way valve 24.
The pipe 23 is connected to the ozonizer 3. In this state, the ozone generated by the ozonizer 3 is supplied to the adsorbent unit 4 via the three-way valves 21 and 22 by the air supply device 3a connected to the ozonizer 3.

A heat exchanger 6 is inserted in the adsorbent unit 4. A medium for absorbing heat is circulated in the heat exchanger 6 by three-way valves 25 and 26, so that heat generated in the adsorbent unit 4 is absorbed. A pipe 35 is connected to the heat exchanger 7 by three-way valves 27 and 28.
36 is connected and the cooling medium is circulated. The ozone supplied to the adsorbent unit 4 is adsorbed on the adsorbent unit 4. The oxygen supplied to the adsorbent unit 4 together with the ozone is returned to the ozonizer 3 via the adsorbent unit 5 and the three-way valves 24 and 23. Here, the ozone reduced by the adsorbent unit 4 is supplemented by converting the oxygen supply source or circulating oxygen into ozone by the ozonizer 3. The above steps are performed until ozone is sufficiently adsorbed on the adsorbent unit 4 as shown in FIG.

In the piping configuration shown in FIG. 5B, after the adsorbent unit 4 has sufficiently adsorbed ozone, FIG.
As shown in (c), switching of the three-way valve is performed. As a result, the ozone generated by the ozonizer 3 is transferred to the three-way valve 2
The ozone is adsorbed to the adsorbent unit 5 by being supplied to the adsorbent unit 5 via 1.24. The oxygen supplied to the adsorbent unit 5 together with the ozone passes through the adsorbent unit 5 and is supplied to the adsorbent unit 4. As described above, when oxygen is supplied to the adsorbent unit 4 to which ozone is sufficiently adsorbed, ozone is released from the adsorbent. And
Due to the release of ozone, the adsorbent unit 4 is cooled, and the medium circulating in the heat exchanger 6 is cooled. The ozone released from the adsorbent is supplied to the ozonizer 3 via the three-way valves 22 and 23. The ozone supplied to the ozonizer 3 is disposed on the three-way valve 21 side by an air supply device connected to the ozonizer 3. The ozone that has been decomposed into oxygen can be converted back into ozone by the ozonizer 3.

In the piping configuration shown in FIG. 6C, the three-way valves 25, 26, 27 and 28 are also switched, and the heat exchanger 6 is connected to the piping 33 and 34 and the heat exchanger 7 is connected to the piping 37 and 38. Have been. The heat exchanger 6 circulates a cooling medium, and the heat exchanger 7 circulates a medium for absorbing the heat of the adsorbent. Thus, in the adsorbent unit 4, the medium flowing into the heat exchanger 6 is cooled by the release of ozone, and in the adsorbent unit 5, the medium flowing into the heat exchanger 7 absorbs the heat of the adsorbent. It is. Then, as shown in FIG. 6D, this piping configuration is maintained until the ozone of the adsorbent unit 4 is sufficiently released, and the ozone is sufficiently adsorbed by the adsorbent unit 5, and thereafter, FIG. ).
As described above, by configuring the cooling device, ozone and oxygen can be circulated, and ozone can be repeatedly adsorbed on the adsorbent and released from the adsorbent. By releasing the ozone adsorbed on the adsorbent, the medium circulating in the heat exchanger inserted into the adsorbent can be cooled. That is, the medium in the heat exchanger is cooled in the adsorbent unit that releases ozone, and the medium in the heat exchanger is heated in the adsorbent unit that stores ozone.

Next, another embodiment will be described. FIG.

5 and heat exchangers 6 and 7. The adsorption units 4 and 5 are filled with silica gel as an adsorbent. The adsorbent units 4 and 5 have openings, and the heat exchangers 6 and 7 are inserted into the openings of the adsorbent units 4 and 5, respectively. The oxygen supply source 2 is connected to the ozonizer 3 by a pipe, and oxygen is supplied from the oxygen supply source 2 to the ozonizer 3. Ozonizer 3
Is connected to the adsorbent unit 4 via a valve 9, and the adsorbent unit 4 is connected to the adsorbent unit 5 by a pipe via a valve 8 and a valve 10. The ozonizer 3 is connected to the adsorbent unit 5 via a pipe via a valve 11. The ozonizer 3 has a built-in air supply device, and is configured to circulate the gas in the pipe.

Next, a cooling process by the cooling device 1 will be described. FIG. 8 is a schematic view showing a cooling step by a cooling device. 8A shows a process in which ozone is adsorbed by the adsorbent unit 4, and FIG. 8B shows a state in which ozone is sufficiently adsorbed by the adsorbent unit 4, and FIG. (C) shows a state in which the adsorbent unit 4 and the adsorbent unit 5 have been exchanged. FIG. 8D shows a process in which the ozone of the adsorbent unit 4 is released and the ozone is adsorbed by the adsorbent unit 5. In FIG. 8, the adsorbent units 4 and 5 are used.
The oblique line indicates the amount of adsorbed ozone.

First, as shown in FIG. 8A, oxygen is supplied from the oxygen supply source 2 to the ozonizer 3. Part of the oxygen supplied to the ozonizer 3 is converted to ozone,
It is introduced into the adsorption unit 4 together with oxygen. Then, the ozone is adsorbed by the adsorbent filled in the adsorbent unit 4. In the present embodiment, as the adsorbent, the adsorbent units 4 and 5 are filled with lica gel, and ozone is adsorbed by silica gel. Ozone generated by the ozonizer 3 is adsorbed by the adsorbent unit 4, and adsorbent oxygen passes through the adsorbent unit 4 together with ozone. The oxygen returns to the ozonizer 3 via the adsorbent unit 5. Then, part of the oxygen is further converted into ozone by the ozonizer 3 and supplied to the adsorbent unit 4. Here, the cooling device 1
Oxygen is supplied from the oxygen supply source 2 to the ozonizer 3 so that the internal pressure becomes constant.

When ozone is adsorbed by the adsorbent unit 4, the adsorbent is warmed by latent heat due to ozone adsorption. Since the heat exchanger 6 is inserted into the adsorbent unit 4, the amount of heat transmitted to the adsorbent is taken out by the heat exchanger 6. This makes it possible to easily discharge the heat generated by the adsorption of ozone.

The step of supplying ozone to the adsorbent 4 is shown in FIG.
As shown in (b), the operation is performed until the ozone adsorption amount of the adsorbent unit 4 reaches saturation by the supply of ozone.
By continuously supplying the ozone supplied from the ozonizer 3 to the adsorbent unit 4, the amount of ozone adsorbed by the silica gel in the adsorbent unit 4 reaches saturation. For this reason, even if ozone is supplied to the adsorbent unit 4 in which the amount of adsorbed ozone has reached saturation, the amount of heat associated with further adsorption cannot be obtained. Then, as shown in FIG. 8C, the adsorbent unit 4 and the adsorbent unit 5 are exchanged. When it is difficult to replace the adsorbent unit, a method such as changing pipes can be used. That is, the valve 9 is connected to the adsorbent unit 5, and the valve 11 is connected to the adsorbent unit 4.
Connect to Thus, the ozone adsorbed by the adsorbent unit can be released and cooled without moving the adsorbent unit. Then, after replacing the adsorbent unit 4 and the adsorbent unit 5, ozone is supplied to the adsorbent unit 5. Ozone is adsorbed in the adsorbent unit 5, and heat accompanying the ozone adsorption is taken out by the heat exchanger 6. On the other hand, oxygen is supplied to the adsorbent unit 4 via the adsorbent unit 5.

The ozone adsorbed on the adsorbent unit 4 is easily released by supplying oxygen. As described above, the ozone adsorbed by the adsorbent is stabilized in the pores of the adsorbent in a clathrated or associated state. Due to this stabilization, ozone is adsorbed to the adsorbent under a condition of 1 to 2 atmospheres and 20 degrees Celsius or less. However, the clathrated or associated and stabilized ozone is easily released from the adsorbent by the supply of oxygen. Therefore, FIG.
As shown in (d), the ozone adsorbed by the adsorbent unit 4 is released from the adsorbent unit 4 by the supply of oxygen, and is supplied to the adsorbent unit 5. The latent heat generated by the release of ozone cools the adsorbent. At this time, the heat exchanger 7 is inserted into the adsorbent unit 4, and the heat exchanger 7 is cooled. That is, the heat exchanger 7
Thereby, the latent heat generated by the release of ozone can be used for cooling.
Since the heat exchanger 7 is cooled by latent heat accompanying the release of ozone from the adsorbent, it is possible to perform cooling in a temperature range in which the fluidity of ozone is maintained.

In the state shown in FIG. 8D, ozone is released from the adsorbent unit 4 and the adsorbent unit 5
, It is not necessary to always operate the ozonizer 3. However, since ozone is decomposed into oxygen, it is necessary to operate the ozonizer 3 to an extent sufficient to compensate for the shortage of ozone and replenish ozone. Therefore, the cooling device 1 can be operated with a small amount of electric power.

Then, in the state shown in FIG.
After the amount of ozone released from the adsorbent unit 4 decreases and ozone is sufficiently adsorbed on the adsorbent unit 5, the adsorbent unit 4 and the adsorbent unit 5 are exchanged, and the same operation is repeated. Thus, the heat generated by the adsorption of ozone is extracted by the heat exchanger 6, and the latent heat generated by the release of ozone is used for cooling by the heat exchanger 7. Since the cooling effect by the release of the ozone from the adsorbent is used, the cooling device 1 can be operated at a temperature of 1 to 2 atm and at a temperature of 20 degrees Celsius or less, and can be safely operated. Further, since the pressure range in which ozone is used is 1 to 2 atm, corrosion of the device due to ozone can be reduced. The cooling device can be operated within a temperature range in which ozone is adsorbed by the adsorbent and can be desorbed. Therefore, cooling can be easily performed even at an extremely low temperature.

[0031]

According to the first aspect of the present invention, since the flow of heat into and out of ozone by adsorption and desorption of the ozone to the adsorbent is utilized, cooling can be performed by a substance which can be easily handled without using a medium such as chlorofluorocarbon. Thereby, the safety of the cooling device can be improved.

As described in the second aspect, ozone is adsorbed and desorbed under a pressure of 1 to 2 atm, so that cooling can be performed safely. In addition, the cost for equipment can be reduced.

As described in the third aspect, ozone is discharged from the adsorbent by supplying oxygen, so that cooling can be easily carried out by oxygen and ozone, and the cost can be easily increased by using a closed system. Cooling can be performed with efficiency.

According to a fourth aspect of the present invention, by utilizing the flow of heat by the adsorption and desorption of ozone to and from the adsorbent,
Since the adsorption-type cooling device that adsorbs and desorbs ozone at a pressure of 2 atm and discharges ozone from the adsorbent by supplying oxygen is configured, a cooling device that does not pollute the environment can be configured. Further, since cooling is performed by the difference in properties between ozone and oxygen, cooling can be easily performed in a closed system.
