Description

OZONE PRODUCTION APPARATUS AND OZONE TREATMENT APPARATUS [0001]

The present invention relates to an ozone generator and an ozone treatment apparatus.

An ozone treatment apparatus for deodorizing and sterilizing a substance to be treated by ozone is widely used. This type of ozone treatment apparatus has an ozone generating device for containing ozone in a fluid (gas or liquid), and a fluid containing ozone is supplied to the object to be treated to obtain necessary effects.

When the ozone generating device contains ozone in the fluid taken in from the outside and then ozone is contained in the fluid in the step taken into the ozone generating device, . For example, in the conventional ozone generating apparatus described in Patent Document 1 or Patent Document 2, when the ozone generating apparatus is used in a closed space, ozone emitted from the ozone generator into the closed space circulates in the closed space There is a risk that the ozone will be deteriorated by the ozone-generating lamp, the power source for supplying power to the lamp, the fan for circulating the fluid, and the like.

In the household goods deodorizing apparatus described in Patent Document 3, air containing ozone generated in the ozone generating apparatus is supplied into the processing chamber, and air after deodorization in the processing chamber is discharged into the atmosphere outside the apparatus. The ozone decomposer is disposed in the discharge passage and the ozone contained in the discharged air is decomposed by the ozone decomposer to lower the ozone concentration. With such a configuration, when a high concentration of ozone exceeding the decomposition performance of the ozone decomposer is filled in the treatment chamber or when the ozone decomposer is deteriorated, the ozone is not sufficiently decomposed and air containing ozone exceeding the environmental standard value leaks out of the apparatus . In addition, the ozone generating device may again blow out the outside air in which ozone remains, and the constituent parts of the ozone generating device may be deteriorated by ozone. Particularly, when an ozone generating apparatus is used as an excimer lamp, a component that efficiently generates ozone at a high concentration becomes a significant problem.

In a deodorizing device such as a locker disclosed in Patent Document 4, a fan, an ozone generator, a reaction chamber, and a catalyst are arranged in this order from the upstream side of the flow of air in an airflow duct provided separately from the storage portion to be deodorized. Unit is provided. The odor component contained in the air sucked into the airflow duct by the rotation of the fan is oxidatively decomposed in the reaction chamber by the ozone supplied by the ozonizer and the deodorized air is discharged from the airflow duct, . At this time, unreacted ozone which has not reacted with the odor component in the reaction chamber is decomposed while passing through the catalyst unit. With such a configuration, there is a problem in that deodorization can not be efficiently performed because the reaction time between the odor component and ozone is short. It is difficult to make the deodorizing device compact by increasing the size of the reaction chamber in order to lengthen the reaction time between the odor component and ozone. The ozone contained in the exhaust air from the airflow duct is decomposed in the catalyst unit provided downstream of the reaction chamber. However, since no measures are taken against ozone contained in the air sucked into the airflow duct from the outside, There is a possibility that the fan or the ozone generator is deteriorated by the ozone contained in the circulating air.

An object of the present invention is to provide an ozone generating device which is less prone to deterioration of parts due to ozone. It is also an object of the present invention to provide an ozone treatment apparatus capable of performing deodorization and sterilization with high efficiency and in which deterioration of parts by ozone is less likely to occur.

The ozone generating apparatus of the present invention includes ozone generating means and ozone removing means disposed upstream of the flow of fluid than the ozone generating means. The ozone removing means removes at least a part of the ozone contained in the fluid, The ozone generating means is characterized in that ozone is contained in the fluid which has passed through the ozone removing means.

The ozone generating apparatus may include an inlet through which the fluid flows and an outlet through which the fluid flows, and ozone generating means may be provided on the flow path between the inlet and outlet.

An ozone generating device comprising an ozone generating device including a lamp for generating ozone by emitting ultraviolet rays and a power source for supplying power to the lamp and including a lamp accommodating chamber for accommodating the lamp and a power storage compartment for accommodating the power, , The fluid introduced from the inlet is divided at the downstream side of the inlet port and flows into the lamp housing chamber and contains a fluid containing ozone by the lamp and a fluid having at least part of ozone removed by the ozone removing means, Are preferably merged on the upstream side of the outflow port and flow out from the outflow port.

A partition wall may be provided between the lamp housing chamber and the power housing chamber so as to shield ultraviolet rays emitted from the lamp against the power source. The fluid introduced from the inlet is classified on the upstream side of the partition, and the sorted fluid merges on the downstream side of the partition and flows out from the outlet. It is preferable that the partition is located on the power source side with respect to the center axis which is the rotation center of the fan that flows the fluid from the inlet to the outlet.

It is preferable that the center of each of the inlet port and the outlet port is disposed closer to the lamp housing chamber than the power storage chamber with respect to the partition wall and the fan is provided on the flow path between the inlet port and the ozone generating means.

The control means may be provided for controlling the operation of the ozone generating means and the operation of the fan and stop the operation of the fan with a time difference after stopping the generation of ozone by the ozone generating means by the control means. Thus, ozone remaining in the fluid can be efficiently removed by the ozone removing means.

The present invention also relates to an ozone treatment apparatus having a treatment chamber in which an object to be treated by ozone is disposed in addition to an ozone generating apparatus having an inlet, an outlet, an ozone generating means and an ozone removing means, The ozone-containing fluid flowing out from the ozone generating means flows from the inlet again after treating the object to be treated through the treatment chamber, and at least a part of the ozone is removed by the ozone removing means on the upstream side of the ozone generating means in the circulation of the fluid Is removed.

Further, in the ozone treatment apparatus of the present invention, after the object to be treated is treated by the fluid containing ozone in the ozone generating means, the fluid from which at least a part of ozone is removed by the ozone removing means flows back into the ozone generating means .

According to the present invention, at least a part of the ozone contained in the fluid is removed by the ozone removing means disposed on the upstream side of the ozone generating means, so that the ozone generating device and the ozone generating device An ozone treatment apparatus can be obtained. In addition, since the restriction on the flow path configuration on the downstream side of the ozone generating means is small, it is possible to obtain an ozone treatment apparatus capable of efficiently deodorizing and sterilizing the object to be treated.

2 is a cross-sectional view showing an internal structure of an ozone generator according to another embodiment of the present invention.
3 is a sectional view showing the internal structure of the ozone treatment apparatus to which the present invention is applied.

The ozone generator 10 shown in Fig. 1 is configured to take in the fluid from the inlet 12 formed in the case 11 and to contain the ozone in the fluid in the case 11, And discharged out. A fan 30, an excimer lamp 31 (ozone generating means), a power source 32 (ozone generating means), and a startup assistant light source 33 are disposed in the case 11.

The case 11 has a pair of substantially paralleled end walls 14 and 15 and a pair of substantially parallel side walls 16 and 17 connecting the end wall 14 and the end wall 15 An inlet 12 is formed in the end wall 14 and an outlet 13 is formed in the end wall 15. Only the four wall portions of the end walls 14 and 15 and the side walls 16 and 17 are shown in the sectional view of FIG. 1. However, in the case 11, portions other than the inlet 12 and the outlet 13 are sealed Structure. The direction in which the side wall 16 and the side wall 17 are connected (the vertical direction in Fig. 1) is the width direction of the case 11. [ In the width direction of the case 11, the inlet port 12 and the outlet port 13 are located approximately at the center of the corresponding end walls 14 and 15, respectively. A partition wall (18) is provided in the case (11). The partition wall 18 is located between the side wall 16 and the side wall 17 in the width direction of the case 11 and is extended substantially parallel to the side wall 16 and the side wall 17, A lamp housing chamber 19 is formed between the side wall 17 and the partition 18 so that the power housing chamber 20 is formed between the side wall 17 and the partition 18. [ The case 11 is provided with an inflow chamber 21 for spatially connecting the inflow port 12 with the lamp housing chamber 19 and the power supply housing chamber 20 and an inflow chamber 21 for connecting the inflow opening 13 and the lamp housing chamber 19, And an outlet chamber (22) for spatially connecting the power supply housing chamber (20) are formed.

The fan 30 is disposed in the inflow chamber 21 at a position adjacent to the inlet 12 and rotates about the central axis 30x. When the fan 30 rotates, a flow of fluid indicated by a thick white arrow in FIG. 1 is generated. The fluid first flows into the inflow chamber 21 from the outside of the case 11 through the inflow port 12 and the inflow fluid is divided into both sides of the partition 18 and stored in the lamp accommodating chamber 19 and the power receiving chamber 20 Passes through the outflow port 13, and is discharged to the outside of the case 11. That is, a flow path through which the fluid flows is formed by upstream of the inlet port 12 and downstream of the outlet port 13, and the flow path is divided in the width direction of the case 11 in the range in which the partition wall 18 is provided. The partition wall 18 is disposed closer to the side wall 17 than the central axis 30x in the width direction of the case 11. [ Therefore, when the fan 30 rotates, the fluid proceeding downstream from the inflow chamber 21 flows predominantly toward the lamp housing chamber 19 side. The center of the inlet port 12 and the center of the outlet port 13 are located at positions substantially coinciding with the center axis 30x of the fan 30 in the width direction of the case 11. [ That is, both the center of the inlet 12 and the center of the outlet 13 are located closer to the side wall 16 (the lamp housing chamber 19) than the partition 18 in the width direction.

The excimer lamp 31 is disposed in the lamp housing chamber 19 and the power source 32 is disposed in the power housing chamber 20. [ The excimer lamp 31 emits ultraviolet rays to generate ozone from surrounding oxygen. The startup assistant light source 33 is mounted on the partition wall 18 and emits ultraviolet rays to facilitate starting of the excimer lamp 31. [ The power source 32 supplies power to the fan 30, the excimer lamp 31, and the startup assistant light source 33. The ozone generating apparatus 10 is provided with an operating section 34 (control means) which can be operated from the outside of the case 11 and operates the operating section 34 to operate the ozone generator 10, (31) can be controlled. For example, when the ozone generator 10 is started, the fan 30 and the excimer lamp 31 are operated almost simultaneously, or the excimer lamp 31 is first turned on, The fan 30 may be rotated. When the ozone generator 10 is stopped, it is possible to stop the rotation of the fan 30 after the excimer lamp 31 is turned off first and a predetermined (predetermined) period of time has elapsed after the excimer lamp 31 is turned off .

The ozone generator 10 also includes an ozone removing unit 40 having an ability to remove ozone. Removal of ozone is a concept that includes the entire function of reducing ozone contained in a fluid such as decomposition or adsorption. Activated carbon or a catalyst for adsorbing and decomposing ozone, a low-pressure mercury lamp for decomposing ozone by emitting light having a wavelength of 254 nm, Any one can be selected as the ozone removing means 40. The ozone removing means 40 is provided at the inlet of the inlet 12 and can lower the ozone concentration of the fluid flowing into the inlet chamber 21 from the inlet 12.

When ozone is contained in the fluid outside the case 11, the ozone generating apparatus 10 having the above-described structure removes at least a part of the ozone by the ozone removing means 40 located on the upstream side The exciter lamp 31, the power source 32, and the startup assistant light source 33, which are disposed in the case 11, are not in contact with the case 11 because the fluid flows into the case 11 through the inlet port 12 It is possible to prevent or reduce deterioration of the component parts due to ozone. The fluid that has flowed into the inflow chamber 21 of the case 11 (fluid having undergone ozone removal by the ozone removal means 40) is generated by the excimer lamp 31 when passing through the lamp chamber 19 Containing ozone at a high concentration. On the other hand, the fluid passing through the power storage chamber 20 keeps the ozone removed by the ozone removing means 40 to cool the power supply 32. Fluids having different ozone concentrations and passing through the lamp housing chamber 19 and the power source housing chamber 20 respectively join together in the outflow chamber 22 and the fluid containing ozone is discharged from the outflow port 13. The concentration of ozone in the fluid flowing from the outlet chamber 22 to the outlet 13 is higher than the fluid flowing from the inlet 12 to the inlet chamber 21. As described above, the ozone generator 10 removes ozone by the ozone removing means 40 provided on the upstream side to efficiently protect the fluid containing the high concentration ozone from the deterioration of the components in the case 11 by ozone Can be supplied to the outside. In addition, the configuration in which the ozone removing means 40 is provided so as to cover the inlet 12 does not impair the compactness of the ozone generating device 10.

In the ozone generator 10, the partition wall 18 provided between the excimer lamp 31 and the power source 32 can protect the power source 32 from the ultraviolet rays emitted by the excimer lamp 31. As described above, by arranging the partition 18 in the width direction of the case 11 closer to the power source 32 (side wall 17) than the central axis 30x of the fan 30, The fluid flowing downstream from the lamp chamber 31 flows predominantly toward the side of the lamp housing chamber 19 having the excimer lamp 31 so that ozone can efficiently be contained in the fluid.

In the ozone generating apparatus 10 described above, the ozone removing unit 40 is provided at a position adjacent to the inlet 12 at the most upstream side. However, the ozone removing unit may be disposed at a different position. In the ozone generator 110 shown in Fig. 2 as an example thereof, the ozone removing unit 140 is disposed upstream of the power source 32 in the power storage room 20. [ According to this configuration, among the fluids classified into the lamp housing chamber 19 and the power housing compartment 20 from the inflow chamber 21, the ozone contained in the fluid that cools the power source 32 through the power source compartment 20, It is possible to prevent or reduce deterioration of the power source 32 due to ozone by removing at least a part of the power source 32 by the ozone removing means 140. [ As described above, a configuration in which ozone removing means is provided in a limited form upstream of a part of constituent elements of the ozone generating means is also effective.

In addition to the ozone removing means 140 shown in Fig. 2, the ozone removing means may be provided on the upstream side of the excimer lamp 31 in the lamp housing chamber 19. In this configuration, as in the case of the ozone generator 10 of Fig. 1, the effect of preventing the deterioration of both the excimer lamp 31 and the power source 32 by ozone can be obtained. As a new modification, it is also possible to dispose ozone removing means in the inflow chamber 21. [ That is, when the condition that the upstream side of the element constituting the ozone generating means is satisfied, it is possible to dispose the ozone removing means at an arbitrary position.

The ozone treatment apparatus 50 shown in Fig. 3 is one in which the ozone generating apparatus 10 of Fig. A treatment chamber 52 for spatially connecting the downstream side of the outflow port 13 in the ozone generator 10 and the upstream side of the inflow port 12 is formed in the outer case 51, The object to be processed 53 is disposed. The fluid introduced into the inflow chamber 21 from the inflow opening 12 is classified into the lamp housing chamber 19 and the power housing compartment 20 by rotating the fan 30 of the ozone generator 10. [ At least a part of the ozone is removed by the ozone removing means 40 in the fluid in the inflow chamber 21 and the fluid passing through the lamp accommodating chamber 19 contains ozone generated by the excimer lamp 31, The fluid passing through the chamber 20 is maintained in a state in which the ozone is removed by the ozone removing means 40. These fluids join together in the outflow chamber 22 and flow out of the outflow port 13 and flow into the processing chamber 52. The fluid containing ozone flowing out of the outlet 13 is subjected to treatment of the object 53 in the treatment chamber 52 and at least part of the residual ozone is removed from the ozone removal means 40, And then flows into the inflow chamber 21 again. With this configuration, even when a fluid containing ozone at a high concentration is supplied to the sealed processing chamber 52 in the outer case 51 by the excimer lamp 31, the ozone generating apparatus 10 The excimer lamp 31, the power source 32, and the startup assistant light source 33 in the ozone generator 10 are lowered by the ozone removing means 40. Therefore, Or the like can be prevented or reduced from being deteriorated by the ozone. Since the ozone removing unit 40 is disposed on the upstream side of the ozone generating apparatus 10, the ozone generating apparatus 10 is not compacted, ), So that it is possible to effectively deodorize and sterilize the object 53. [0157] The ozone treatment apparatus 50 of FIG. 3 includes the ozone generator 10 of FIG. 1 in the outer case 51 but may be provided in the outer case 51 of another type such as the ozone generator 110 of FIG. The ozone generating means may be provided.

The operation of the ozone treatment apparatus 50 shown in Fig. 3 is carried out by the operation unit 34 provided in the case 11 of the ozone generator 10 or the operation unit provided in the outer case 51 of the ozone treatment apparatus 50 ). As an example of the operation mode, the excimer lamp 31 is first turned on by irradiating the startup assistant light source 33. [ The fan 30 is rotated after a predetermined (predetermined) period of time has elapsed since the excimer lamp 31 was turned on. Ozone can be contained in the remaining fluid in the lamp housing chamber 19 by first turning on the excimer lamp 31 so that the fluid contained in the ozone can be introduced into the case 11 from the initial stage of starting the ozone generator 10, As shown in Fig. The excimer lamp 30 may be turned on and the fan 30 may be rotated at substantially the same time or the excimer lamp 30 may be turned on after the fan 30 is rotated.

After the object 53 is processed in the processing chamber 52, the excimer lamp 31 is turned off. The operation of the ozone generator 10 is stopped by stopping the rotation of the fan 30 at a time difference after the excimer lamp 31 is turned off. Ozone is not contained in the fluid passing through the lamp housing chamber 19 and the fluid passing through the power source housing chamber 20 is supplied to the ozone removing means 40 by at least a part of the ozone removing means 40 Since the removed state is maintained, the ozone concentration of the fluid flowing out of the outlet 13 is lowered. The fluid flowing out of the outlet 13 passes through the treatment chamber 52 and at least part of the ozone is removed again from the ozone removing means 40 and then flows into the inflow chamber 21 from the inlet 12 again. That is, even after the excimer lamp 30 is turned off, the circulation of the fluid is continued by rotating the fan 30, whereby the fluid flowing in the ozone treatment apparatus 50 (in the ozone generator 10 and in the treatment chamber 52) The ozone contained in the ozone is gradually removed by the ozone removing means. With this operation, the ozone concentration in the ozone treatment device 50 can be efficiently lowered to the environmental standard value or lower, and the ozone treatment device 50 can be safely used. The control for stopping the rotation of the fan 30 after turning off the excimer lamp 31 (stopping the generation of ozone) can be controlled to stop automatically after a predetermined (predetermined) period of time has elapsed. An ozone sensor (not shown) for detecting whether ozone of a predetermined concentration or higher is contained may be provided in the case 11 of the ozone generator 10 or the outer case 51 of the ozone treatment device 50 Do. In this configuration, it is possible to control the fan 30 to stop when the concentration of ozone detected by the ozone sensor becomes equal to or less than a predetermined value after the excimer lamp 31 is turned off (generation of ozone is stopped). Further, the manner of operation of the ozone treatment device 50 is not limited to the above, and can be properly controlled.

In the ozone generating apparatuses 10 and 110 of the respective embodiments described above, the inlet port 12 and the outlet port 13 are arranged substantially at the center in the width direction of the case 11. [ The inlet 12 and the outlet 13 may be arranged closer to the side of the lamp housing chamber 19 (the side wall 16) in the width direction of the case 11. [ The center of each of the inlet port 12 and the outlet port 13 in the width direction of the case 11 is located closer to the lamp housing chamber 19 (side wall 16) than the power storage chamber 20 with respect to the partition wall 18 The inflow port 12 and the outflow port 13 may be arranged close to the lamp housing chamber 19 with respect to the end walls 14 and 15 of the case 11 as well. This arrangement makes it easier for the fluid to be classified in the case 11 to flow into the lamp housing chamber 19 side and efficiently perform the inclusion of ozone in the fluid by the excimer lamp 31. [

The ozone generator and the ozone treatment apparatus of the present invention can be applied to either a gas or a liquid as a fluid containing ozone. The ozone generating apparatuses 10 and 110 and the ozone treatment apparatus 50 of the embodiment each have an excimer lamp 31 as ozone generating means and a gas (air) is suitable as the fluid containing ozone. However, by appropriately changing the configuration of the ozone generating means and the like, it is also applicable to an ozone generating apparatus and an ozone processing apparatus of a type using liquid as a fluid. In addition to the excimer lamp 31, a low-pressure mercury lamp or a discharge method (discharge method) is applicable as the ozone generating means.

The ozone generating apparatuses 10 and 110 and the ozone processing apparatus 50 are not limited to the above-described embodiments. The present invention is adaptable to an ozone generating apparatus having ozone generating means and a general ozone processing apparatus.
