[0040] [First embodiment]

[0041] <Overview of Deodorization System>

[0042] Figure 1 It is a schematic diagram which shows the whole structure of the deodorization system A of 1st Embodiment.

[0043] The deodorization system A comprises: an apparatus 2 having a coating device 1 for coating a film with a coating liquid to form a coating, a recovery device 3 for recovering odor generated by the apparatus 2, a preparation device 4 for preparing a combustion material containing a surplus raw material of the coating liquid, and a deodorization device 6 having a deodorization furnace 5 for burning the recovered odor together with the combustion material. The recovery device 3 is attached to the apparatus 2.

[0044] Figure 1 The thin arrows indicate the feeding direction of the combustion materials and fossil fuels, and the hollow arrows indicate the flow of odor and exhaust gas.

[0045] The equipment 2 with the recovery device 3 is usually arranged in a building B. In the example shown in the figure, one equipment 2 is arranged in one building B, but a plurality of equipment 2 may be arranged in one building (not shown).

[0046] The above-mentioned equipment 2 has a coating device 1 and has any other appropriate device. The above-mentioned coating device 1 is not particularly limited as long as it is a device that can apply a coating liquid on a film to form a coating. For example, as the coating device 1, there can be cited a device that applies an adhesive liquid (or adhesive liquid) on the surface of the film to form an adhesive layer (or adhesive layer) on the above-mentioned film; a device that applies any functional solution on the surface of the film to form a functional layer on the above-mentioned film; a device that prints ink on the film to form a printed layer, etc. For example, in the case where the coating device 1 is a device for forming an adhesive layer (or adhesive layer), the adhesive liquid (or adhesive liquid) is equivalent to the coating liquid, and the adhesive layer (or adhesive layer) is equivalent to the coating layer. For example, in the case where the coating device 1 is a device for forming a functional layer, the functional solution is equivalent to the coating liquid, and the functional layer is equivalent to the coating layer. For example, in the case where the coating device 1 is a printing device, the ink is equivalent to the coating liquid, and the printed layer is equivalent to the coating layer.

[0047] The film is not particularly limited, and optical films, films other than optical films, etc. can be cited. As optical films, polarizing films, phase difference films, anti-reflection films, light diffusion films, brightness enhancement films, light reflection films, surface protection films, etc. can be cited. As films other than optical films, release liner, isotropic film, etc. can be cited. From the viewpoint of material, the above-mentioned film generally uses resin film, but can also be a film other than resin film. As films other than resin film, paper, synthetic paper, nonwoven fabric, fabric, etc. can be cited.

[0048] The recovery device 3 mainly recovers the odor generated by the above-mentioned coating device 1. The recovered odor is sent to the gathering section 32. When the gathering section 32 is filled with odor and reaches a certain concentration, the odor is sent from the gathering section 32 to the deodorizing furnace 5. It should be noted that the odor is not limited to the case where it is generated by the coating device 1. In the case where the odor is generated by a device other than the coating device 1 in the device provided in the above-mentioned equipment 2, the odor can also be recovered and sent to the deodorizing furnace 5 through the gathering section 32. It should be noted that the recovered odor can also be sent directly to the deodorizing furnace 5 without passing through the gathering section 32.

[0049] The excess raw material of the coating liquid is a raw material that is superfluous among the raw materials constituting the coating liquid. In one embodiment, the excess raw material is used to deodorize odor by a combustion method.

[0050] That is, the coating liquid to be applied to the above-mentioned film can be prepared by mixing various raw materials according to the type of coating to be formed. Therefore, the coating liquid is composed of a mixture of two or more raw materials. The coating liquid contains, for example, an active ingredient and an organic solvent that dissolves the active ingredient, and contains any additives as needed. The above-mentioned active ingredient is, for example, a compound containing carbon in the molecule, and the above-mentioned organic solvent is also a compound containing carbon in the molecule. Usually, a given amount of such two or more raw materials is prepared in advance, and they are mixed in a given ratio to prepare the coating liquid. However, due to various circumstances, the raw materials prepared in advance are sometimes left over and are not made into a coating liquid. In one embodiment of the present invention, in order to deodorize the odor, the excess raw material (residual raw material) is effectively used as a combustion material in the deodorizing furnace 5.

[0051] In addition, the coating liquid itself may remain due to various circumstances. In another embodiment of the present invention, in order to deodorize the odor, the excess coating liquid is effectively used as a combustion material in the deodorizing furnace 5. Hereinafter, the excess coating liquid is referred to as "excess coating liquid".

[0052] The following is a specific description.

[0053] <Equipment with coating device>

[0054] Although several equipments 2 including the coating device 1 are exemplified, the coating device 1 and the equipment 2 are not limited to these equipments.

[0055] Figure 2 An exemplary device 2 with a coating apparatus 1 is shown. Figure 2 The thin arrows indicate the transport direction of the film, and the hollow arrows indicate the flow of the odor ( Figure 3 Same).

[0056] Reference Figure 2The device 2 has: a conveying device 23 for conveying a film 28 from a unwinding section 21 to a winding section 22, a coating device 1 for applying an adhesive liquid 71 as a coating liquid to the above-mentioned film 28, a drying device 24 for drying the coating layer, i.e., the adhesive layer 72 formed on the above-mentioned film 28 and recovering the odor, and a bonding device 25 for bonding another film 29 to the above-mentioned adhesive layer 72.

[0057] The unwinding section 21 is arranged on the upstream side of the conveying direction of the film 28, and the winding section 22 is arranged on the downstream side of the conveying direction of the film 28. The coating device 1 continuously applies the adhesive liquid 71 on the surface of the film 28 that is continuously conveyed from the upstream side of the conveying direction to the downstream side of the conveying direction. By applying the adhesive liquid 71 and drying it, an adhesive layer 72 is formed on the surface of the film 28. The coating device 1 is not particularly limited, and a conventionally known coating device can be used. For example, as the coating device 1, a die coater, a gravure coater, a reverse coater, a wire rod coater, etc. can be cited. In the example shown in the figure, a die coater is exemplified.

[0058] The adhesive liquid 71 (coating liquid) contains an adhesive as an active ingredient and an organic solvent, and may contain any other appropriate additives. The adhesive liquid 71 prepared to a given viscosity is obtained by mixing the above-mentioned raw materials (adhesive liquid raw materials) such as the adhesive and the organic solvent in a given ratio.

[0059] The viscosity of the adhesive liquid 71 is adjusted to a viscosity suitable for coating, for example, 100 mPa·s to 1000 mPa·s at 23° C. The viscosity of the adhesive liquid is a value measured at 23° C. using a commercially available E-type viscometer. The coating device 1 is filled with the adhesive liquid 71 prepared above.

[0060] The drying device 24 is disposed on the downstream side of the coating device 1. The fluidity of the adhesive layer 72 just after being coated by the coating device 1 is high, and therefore, the organic solvent must be volatilized. The drying device 24 volatilizes the organic solvent from the adhesive layer 72 just after being coated, and recovers the volatilized organic solvent (odor). Therefore, in the present embodiment, the drying device 24 is equivalent to the recovery device 3 for recovering the odor. The drying device 24 includes: a chamber 241 through which the film 28 can pass, a drying mechanism (not shown) disposed in the chamber 241, and a recovery mechanism 31 disposed in the chamber. The chamber 241 includes an inlet for the transported film 28 to enter, and an outlet for the film 28 to be sent out. When the drying mechanisms are roughly divided, there are mechanisms that actively dry, and mechanisms that passively dry. As an active drying mechanism, for example, there can be mentioned: a method in which a heating mechanism such as an oven is arranged separately from the adhesive layer and the adhesive layer is heated by the heating mechanism; a method in which heated wind or wind at an ambient temperature is blown to the adhesive layer, etc. As a passive drying mechanism, natural drying can be mentioned. These drying mechanisms can be used alone or in combination of two or more. As a representative example of the recovery mechanism 31, an aspirator can be mentioned. The drying mechanism causes the organic solvent to volatilize from the adhesive layer and exist in the chamber. The volatilized organic solvent (odor) is sucked and recovered by the recovery mechanism 31, and after being sent to the gathering section 32 through the piping, it is sent to the deodorizing furnace 5.

[0061] The laminating device 25 laminates the other film 29 onto the dried adhesive layer 72. In this way, a laminate consisting of the film 28 / adhesive layer 72 / other film 29 is obtained. The obtained laminate is wound up in the winding unit 22.

[0062] Figure 3 A further exemplary system 2 with a coating device 1 is shown.

[0063] Reference Figure 3 The device 2 comprises: a conveying device 23 for conveying a film 28 from an unwinding section 21 to a winding section 22, a coating device 1 for coating a functional solution 73 as a coating liquid on the film 28, a drying device 24 for drying the coating layer, i.e., the functional layer 74, formed on the film 28 and recovering odor, and a curing device 26 for curing the functional layer.

[0064] Figure 3The coating device 1 is a device for forming a functional layer 74 on a film 28. The functional layer 74 is not particularly limited, and examples thereof include a hard coating layer, an anti-glare layer, an anti-reflection layer, and the like. The functional solution 73 for forming the functional layer 74 can be appropriately selected according to the type of the functional layer 74. The functional solution 73 (coating liquid) contains an active ingredient for exhibiting its function, and an organic solvent, and may also contain any other appropriate additives. The functional solution 73 adjusted to a given viscosity is obtained by mixing the above-mentioned active ingredients and raw materials such as organic solvents in a given proportion. The above-mentioned functional solution 73 is also prepared to a viscosity suitable for coating in the same manner as the above-mentioned adhesive solution 71. The coating device 1 is filled with the functional solution 73 prepared as above.

[0065] Since the fluidity of the functional layer 74 immediately after being coated by the coating device 1 is high, the organic solvent must be volatilized. Figure 3 The drying device 24 also volatilizes the organic solvent from the functional layer 74 just after coating, and recovers the volatilized organic solvent (odor). Figure 3 The drying device 24 is Figure 2 The drying device 24 is similar in structure to the drying device 24, and the volatile organic solvent (odor) is sucked and recovered by the recovery mechanism 31. The curing device 26 is a device for curing the dried functional layer 74. The curing device 26 can be appropriately set according to the type of active ingredient of the functional solution. For example, in the case where the active ingredient of the functional solution includes a light-curing resin such as an ultraviolet curing resin, a light irradiator such as an ultraviolet light is used as the curing device 26. It should be noted that in the case where the functional layer 74 is a layer that will be fully cured by drying, the above-mentioned curing device can be omitted.

[0066] It should be noted that, although one coating device 1 is provided in the above-mentioned device 2, more than two coating devices (not shown) may also be provided in one device. In addition, a recovery device 3 (a drying device 24 in the example shown) for recovering odor is provided in the above-mentioned device 2, but more than two recovery devices (not shown) may also be provided in one device. In addition, as required, the above-mentioned device 2 may also be equipped with other arbitrary devices. As other arbitrary devices, there may be cited (a) a device for stacking any other film on a film, (b) a device for peeling any film from a stacked film, (c) a device for forming any layer on a film, (d) a device for stretching a film, (e) a device for cutting a film, and the like.

[0067] <Preparation equipment>

[0068] The preparation device 4 is a device for preparing a combustion material including at least one of the remaining raw material of the coating liquid and the remaining coating liquid.

[0069] As described above, at least one of the remaining raw material and the remaining coating liquid is used as a combustion material, but when the remaining raw material and / or the remaining coating liquid are used directly, the viscosity is too high in many cases and the liquid cannot be delivered. In addition, when the remaining raw material and / or the remaining coating liquid are used directly, there is a hidden danger that they cannot be fully burned in the deodorizing furnace 5. Therefore, in the preparation device 4, the remaining raw material and / or the remaining coating liquid are adjusted to an appropriate viscosity to prepare the combustion material. It should be noted that (even if the remaining raw material and / or the remaining coating liquid are not prepared) when the remaining raw material and / or the remaining coating liquid itself has an appropriate viscosity, the preparation process of the preparation device and the combustion material can also be omitted. In this case, the remaining raw material itself and / or the remaining coating liquid itself is used as a combustion material.

By using the mixer 43 to mix the first remaining raw material 81 and the second remaining raw material 82, a combustion material 83 of a given concentration is obtained. The reserve tank 44 is connected to a pipe connected to the mixer 43, through which the combustion material 83 produced by the mixer 43 is supplied to the reserve tank 44. The combustion material 83 in the reserve tank 44 is sent to the deodorizing furnace 5 through the pipe. As a power source for transferring the remaining raw materials and the combustion material, a pump or the like is usually used, but the power source is not shown. It should be noted that a buffer tank 45 for temporarily storing the combustion material can also be provided between the reserve tank 44 and the deodorizing furnace 5.

[0078] The remaining coating liquid 85 is supplied to the first tank 46 through piping or the like. The viscosity adjusting liquid 86 is supplied to the second tank 47 through piping or the like. The remaining coating liquid 85 is a coating liquid that is left over due to various circumstances in the coating liquid used by the coating device 1, such as the above-mentioned adhesive liquid, functional solution, ink, etc. As the viscosity adjusting liquid 86, an organic solvent can be used representatively. As the viscosity adjusting liquid 86 added to the remaining coating liquid 85 when making the combustion material, for example, a remaining raw material (organic solvent) can be used.

[0079] The mixer 48 may be connected to pipes connected to the first tank 46 and the second tank 47, respectively, and the remaining coating liquid 85 and the viscosity adjusting liquid 86 are respectively supplied to the mixer 48 through the pipes.

The obtained combustion material 83 and Figure 4 The preparation device 4 is similarly supplied to the storage tank 44 and then sent to the deodorizing furnace 5. As a power source for transferring the remaining coating liquid, the combustion material, etc., a pump is usually used, but the power source is not shown. It should be noted that a buffer tank 45 for temporarily storing the combustion material can also be provided between the storage tank 44 and the deodorizing furnace 5.

[0080] Figure 6 A preparation device 4 for preparing a combustion material from a surplus raw material and a surplus coating liquid is illustrated. Figure 6 The thin arrows indicate the feed direction of the remaining raw material, the remaining coating liquid and the combustion material.

The first surplus raw material 81 is, for example, an adhesive, the second surplus raw material 82 is, for example, an organic solvent, and the surplus coating liquid 85 is, for example, an adhesive liquid. In the preparation device 4 of this example, since an organic solvent is used as the second surplus raw material 82, the second surplus raw material 82 in the third tank 46a can be omitted. Figure 5 The viscosity adjusting liquid described in the preparation apparatus 4 is shown.

[0084] The mixer 49a is connected to pipes connected to the respective tanks, and the first remaining raw material 81, the second remaining raw material 82, and the remaining coating liquid 85 are respectively supplied to the mixer 49a through the pipes.

[0085] <Deodorization device>

[0086] The deodorizing device 6 is a device that substantially deodorizes odor.

[0087] The deodorizing device 6 includes a deodorizing furnace 5 for burning and oxidatively decomposing odor, and other devices may be provided as necessary.

[0088] Figure 7 An example of the deodorizing device 6 is shown. Figure 7 The thin arrows indicate the feeding direction of the mixed gas, and the hollow arrows indicate the flow of odor and exhaust gas.

[0089] For example, the deodorizing device 6 includes a deodorizing furnace 5 equipped with a heat storage device 61, a waste heat boiler 62, and an exhaust unit 63. The deodorizing furnace 5 includes a frame 52 that partitions a combustion chamber 51, a heat storage device 61 attached to the frame 52, a combustion material supply unit 53 that supplies a combustion material into the combustion chamber 51, a fuel supply unit 54 that supplies a fossil fuel into the combustion chamber 51, an odor introduction unit 55 that introduces odor, and an exhaust gas exhaust unit 56 that exhausts exhaust gas generated after the odor is burned. It should be noted that the heat storage device 61 can be provided as needed.

[0090] The frame 52 is made of a container body with high heat resistance such as metal. The combustion material supply unit 53 includes: a delivery unit 531 (pump, etc.) that pressurizes the combustion material containing the remaining raw material and / or the remaining coating liquid produced by the preparation device 4 and delivers it to the combustion chamber 51, an air introduction unit 532 (compressor, etc.) that introduces air and pressurizes and delivers it, an ejection unit 533 (spray nozzle, etc.) installed on the frame 52 and ejects the mixed gas of the above-mentioned combustion material and air into the combustion chamber 51, and pipes connecting the ejection unit 533 from the above-mentioned delivery unit 531 and connecting the ejection unit 533 from the air introduction unit 532. The above-mentioned pipes merge in the middle of the delivery unit 531 and the air introduction unit 532, and the air and the combustion material are mixed in the middle of the pipes. Therefore, the mixed gas formed by the mixture of the combustion material and the air becomes mist and is ejected from the ejection unit 533. Hereinafter, the mixed gas containing the combustion material and the air is referred to as "combustion material mixed gas". The combustible mixed gas ejected from the ejection portion 533 is burned in the combustion chamber 51, thereby oxidizing and decomposing the odor. In addition, a blower outlet 534 is provided around the ejection portion 533. The blower (multi-blade fan, etc.) is provided to disperse the mist-like combustible mixed gas ejected from the ejection portion 533.

[0091] The fuel supply unit 54 includes a delivery unit 541 (pump, etc.) that pressurizes the fossil fuel stored in the fuel tank and delivers it to the combustion chamber 51, an air intake unit 542 (compressor, etc.) that introduces air and pressurizes it and delivers it, an ejection unit 543 (spray nozzle, etc.) that is installed on the frame 52 and ejects the mixed gas of the fuel and air into the combustion chamber 51, and pipes that connect the ejection unit 543 from the delivery unit 541 and the ejection unit 543 from the air intake unit 542. The fuel supply unit 54 can adopt the same structure as the combustion material supply unit 53.

[0092] The heat storage device 61 is provided to heat the odor.

[0093] The heat storage device 61 is not particularly limited, and a conventionally known heat storage device can be used. The figure shows an example of a rotary heat storage device. In such a rotary heat storage device 61, the heat storage chamber is divided into a plurality of chambers, and each chamber is filled with a heat storage body. The odor introduced into the gas chamber 57 from the odor inlet portion 55 passes through the heat storage chamber 611 (hereinafter referred to as the first heat storage chamber) and is supplied to the combustion chamber 51. The odor that has passed through the first heat storage chamber 611 is heated by the heat storage body and is supplied to the combustion chamber 51 in a state where it has reached a high temperature. On the other hand, the exhaust gas obtained by burning the odor in the combustion chamber 51 passes through another heat storage chamber 612 (hereinafter referred to as the second heat storage chamber) and is discharged from the exhaust gas discharge portion 56. The exhaust gas that has passed through the second heat storage chamber 612 releases heat in the heat storage body and is discharged at a relatively low temperature. Such a rotary heat storage device is well known in the art, for example, it has been disclosed in Japanese Patent Application Publication No. 2006-300399, and therefore, no further description is given here. It should be noted that the heat storage device 61 is not limited to a rotary type, and may also be a switching gas supply and exhaust method as disclosed in WO2013 / 077079, for example.

[0094] The waste heat boiler 62 is a device that effectively utilizes energy and is a conventionally known device that recovers heat from exhaust gas and generates steam, etc. from the heat. The exhaust gas that has passed through the waste heat boiler 62 is discharged from the exhaust section 63 .

[0095] <Deodorization system operation and deodorization method>

[0096] (Odor recovery process)

[0097] Reference Figure 1 to Figure 3 , the equipment 2 having the coating device 1 is put into operation.

[0098] As mentioned above, in Figure 2 The coating device 1 is filled with a binder liquid 71 of a given viscosity containing a binder as an active ingredient and an organic solvent. Figure 3 The coating device 1 is filled with a functional solution 73 containing an active ingredient and an organic solvent. Figure 2 The operation of the device 2 having the coating device 1 is described, but Figure 3 The device 2 also recovers odor from the coating device 1 through the recovery device 3.

[0099] After the film 28 is unwound from the unwinding section 21, it is transported to the downstream side, and an adhesive liquid is applied to the surface of the film 28 by the coating device 1. After the adhesive liquid is applied, the film 28 is transported to the drying device 24 to volatilize the organic solvent from the adhesive layer 72 (the adhesive liquid extending in layers on the surface of the film) as a coating. The volatilized organic solvent as an odor is recovered by the recovery device 3 and sent to the gathering section 32. Through the above drying, an adhesive layer 72 with high adhesion is formed on the surface of the film 28. Next, another film 29 is bonded to the surface of the above adhesive layer (the surface on the opposite side of the film 28) by the bonding device 25. The obtained laminate is wound up in the winding section 22. By keeping the device 2 working, the gathering section 32 is continuously filled with an organic solvent as an odor. Organic solvents are representative volatile organic compounds (VOCs), and they must be deodorized.

[0100] (Process for preparing combustion materials)

[0101] The combustion material is prepared at a different time from the recovery of the odor or simultaneously with the recovery of the odor.

[0102] Reference Figure 1 and Figure 4 , the first remaining raw material 81 is supplied to the first tank 41 of the preparation device 4, and the second remaining raw material 82 is supplied to the second tank 42 of the preparation device 4. For example, the adhesive is supplied to the first tank 41, and the organic solvent is supplied to the second tank 42. The adhesive and the organic solvent are the remaining raw materials in the raw materials of the adhesive liquid. For example, the adhesive remaining when the adhesive liquid 71 used in the coating device 1 of the device 2 is prepared is supplied to the first tank 41, and the organic solvent remaining when the adhesive liquid 71 is prepared is supplied to the second tank 42 (refer to Figure 1 dashed line).

[0103] The first remaining raw material 81 and the second remaining raw material 82 supplied to the first tank 41 and the second tank 42 are respectively measured for viscosity, temperature, etc. while being slowly stirred by the stirrers 411 and 421. When the first remaining raw material 81 is an adhesive, its viscosity is, for example, 100 mPa·s or more and 1000 mPa·s or less at 23° C., and when the second remaining raw material 82 is an organic solvent, its viscosity is about 1 mPa·s.

[0104] Here, the viscosity of the remaining raw materials such as the first remaining raw material and the combustible material refers to a value measured at 23° C. using a commercially available E-type viscometer.

[0105] Next, a predetermined amount of binder (first remaining raw material 81) is supplied from the first tank 41 to the mixer 43, and a predetermined amount of organic solvent (second remaining raw material 82) is supplied from the second tank 42 to the mixer 43. The binder and organic solvent supplied to the mixer 43 are stirred and mixed by the stirrer 431, and the viscosity and temperature thereof are measured. The mixture having a predetermined viscosity is used as the combustion material 83.

[0106] The combustible material 83 is in a liquid state, and its viscosity is, for example, 1 mPa·s to 50 mPa·s, preferably 1 mPa·s to 40 mPa·s at 23° C. The combustible material 83 in such a viscosity range is easily mixed with air in the combustible material supply unit 53, and can be ejected from the ejection unit 533 in a good mist state.

[0107] In order to obtain the combustion material 83 having the viscosity in the above range, a given amount of the binder (the first remaining raw material 81) and the organic solvent (the second remaining raw material 82) are supplied to the mixer 43. In detail, in the preparation device 4, the viscosity of the predetermined combustion material 83 is set in the control unit (not shown) of the preparation device 4. The viscosity of the binder (the first remaining raw material 81) supplied to the first tank 41 and the viscosity of the organic solvent (the second remaining raw material 82) supplied to the second tank 42 are already clear when the coating liquid is prepared. Therefore, in order to obtain the combustion material of the viscosity set by the above control unit, the mixing ratio of these raw materials can be calculated. The amount of raw materials to be mixed is pre-set in the control unit of the preparation device 4, or the control unit calculates and stores it. It should be noted that by measuring the viscosity of the first remaining raw material 81 in the first tank 41 and measuring the viscosity of the second remaining raw material 82 in the second tank 42, it is possible to confirm whether the viscosity of the binder (the first remaining raw material 81) and the organic solvent (the second remaining raw material 82) is a known viscosity. Furthermore, the control unit of the preparation device 4 supplies a predetermined amount of binder (first remaining raw material 81) and a predetermined amount of organic solvent (second remaining raw material 82) to the mixer 43, and measures the viscosity in the mixer 43 to confirm whether a mixture (combustion material 83) having a set viscosity is produced. If the set viscosity is not reached, the binder or organic solvent is further supplied to the mixer 43 to adjust the viscosity, thereby obtaining a combustion material having the above-mentioned viscosity range.

[0108] In addition, a raw material whose viscosity is unknown may be used. In this case, the viscosity of the first remaining raw material 81 and the second remaining raw material 82 is stored in the control unit of the preparation device 4 by supplying them to the first tank 41 and the second tank 42 and measuring the viscosity, and the amount of the first remaining raw material 81 and the second remaining raw material 82 supplied to the mixer 43 is determined by calculation of the control unit.

[0109] Such control of the production device 4 can be performed based on a programmed electronic computer. It should be noted that the same is true for other devices such as the coating device 1.

[0110] The combustion material 83 having the above-mentioned viscosity is supplied to the reserve tank 44 and stored. The viscosity of the combustion material 83 can also be measured in the reserve tank 44 as needed. By measuring the viscosity in the reserve tank 44, it can be confirmed again whether the viscosity of the combustion material 83 is within the allowable range. The combustion material 83 in the reserve tank 44 is sent to the buffer tank 45 when the deodorizing furnace 5 is in operation, and is further sent to the deodorizing furnace 5.

[0111] It should be noted that the preparation of the combustion material is not limited to Figure 4 In the case of using the device 4 for preparing the combustion material containing the residual raw material as shown, it is also possible to use the device 4 as shown. Figure 5 Alternatively, the apparatus for preparing a combustion material containing a residual coating liquid as shown in Figure 6 The apparatus for preparing a combustion material including a surplus raw material and a surplus coating liquid is shown. The viscosity of the combustion material including the surplus coating liquid is also adjusted to, for example, 1 mPa·s or more and 50 mPa·s or less, preferably 1 mPa·s or more and 40 mPa·s or less at 23°C. The viscosity of the combustion material including the surplus raw material and the surplus coating liquid is also adjusted to, for example, 1 mPa·s or more and 50 mPa·s or less, preferably 1 mPa·s or more and 40 mPa·s or less at 23°C.

[0112] (Odor-free process)

[0113] If the odor is accumulated in the accumulation section 32, the odor is sent to the deodorizing furnace 5 at an appropriate time to be deodorized.

[0114] Reference Figure 1 and Figure 7 , the odor is sent from the gas chamber 57 of the heat storage device 61 to the first heat storage chamber 611 through the odor introduction part 55, and is heated while passing through the first heat storage chamber 611. The odor that has reached a high temperature enters the combustion chamber 51 from the first heat storage chamber 611 and is burned. The odor after combustion is decomposed into exhaust gas (odorless gas such as water and carbon dioxide), and the exhaust gas enters the second heat storage chamber 612 from the combustion chamber 51. In the second heat storage chamber 612, the heat of the exhaust gas is transferred to the heat storage body, and the exhaust gas that has reached a relatively low temperature is discharged from the exhaust part 63 after passing through the waste heat boiler 62. If the combustion is continued, the temperature of the heat storage body of the first heat storage chamber 611 is lowered, and the temperature of the second heat storage chamber 612 is raised. Therefore, the exchange action of allowing the odor to enter the second heat storage chamber 612 and the exhaust gas to enter the first heat storage chamber 611 is timely performed, and this exchange action is repeated.

[0115] On the other hand, in order to make the odor burn in the combustion chamber 51, the combustible material is supplied to the combustion chamber 51 after passing through the combustible material supply part 53. The combustible material supply part 53 mixes the combustible material with air and sprays (sprays) the combustible material mixed gas from the spray part 533. In the above-mentioned combustible material mixed gas, the combustible material becomes mist and is sprayed into the combustion chamber 51. Mist means that the combustible material becomes countless fine particles. If the combustible material mixed gas containing the misted combustible material is sprayed, it will ignite in the combustion chamber 51. At the same time as the combustible material mixed gas is sprayed, air is blown from the vicinity of the spray part 533 to the central part of the combustion chamber 51 by the blower. The wind speed of the above-mentioned blower is not particularly limited. From the viewpoint of rectifying the flame formed by the combustible material mixed gas, for example, 5m 3 / min or more and 20m 3 / min or less, preferably 10m 3 / min or more and 15m 3 The wind speed mentioned above refers to the wind volume just after it is blown out from the air outlet 534.

[0116] For the mixing ratio of the combustible material and the air, for example, the air is 3 to 11 parts by mass relative to 1 part by mass of the combustible material, preferably 6 to 8 parts by mass. By mixing the combustible material and the air in such a range of mixing ratios, the combustible material can be burned without any residue.

[0117] In addition, the ejection pressure of the combustion material mixed gas is not particularly limited. In order to make the above-mentioned combustion material mixed gas disperse well in the combustion chamber 51 without causing clogging in the ejection portion 533, the ejection pressure of the above-mentioned combustion material mixed gas is, for example, not less than 0.3MPa and not more than 1MPa, preferably not less than 0.4MPa and not more than 0.8MPa. As mentioned above, the combustion material has a viscosity of not less than 1mPa·s and not more than 50mPa·s, so the combustion material mixed gas can be ejected at an ejection pressure within the above range. In addition, the combustion material in the above-mentioned viscosity range is easy to mix with air, and it is also possible to make the combustion material pass through the ejection portion 533 (spray nozzle, etc.) and become a mist and eject it into the combustion chamber 51.

[0118] By using the combustible material in the above-mentioned viscosity range, the combustible material mixed gas easily flies far away in the combustion chamber 51, and the odor can be burned well in the combustion chamber 51. In particular, by blowing the wind E from the blowing port 534 arranged around the ejection part 533 to the combustion chamber 51, the flame F formed by the combustible material mixed gas is adjusted, and the flame F can spread to a farther place, and the odor is oxidized and decomposed without omission in the combustion chamber 51. In addition, due to the above-mentioned wind E, the combustible material mixed gas is not easy to burn near the ejection part 533, so that the frame 52 and the ejection part 533 can be prevented from being deteriorated at an early stage.

[0119] In the case where a combustible material containing residual raw materials and / or residual coating liquid can be produced in a relatively large amount, the odor can be burned only by the combustible material. Although it depends on the amount of odor treated, when the deodorization of the odor is insufficient only by the combustion of the combustible material mixed gas, a fossil fuel is used in combination. When the combustible material is prepared from the residual raw materials of the coating liquid and / or the residual coating liquid, there is sometimes no residual raw material and / or residual coating liquid to the extent that a given amount of odor can be deodorized. In such a case, the fossil fuel is supplied to the combustion chamber 51 from the fossil fuel tank 58 through the fuel supply unit 54, and is burned together with the combustible material. As fossil fuels, natural gas, petroleum, coal, etc. can be cited, and natural gas such as LNG is generally used. In the case of using fossil fuels, in order to reduce the amount of fossil fuels used, it is also preferred to use the combustible material in combination with the fossil fuel to deodorize the odor. The combustion of odor using fossil fuels is well known in the art, and in the case of using fossil fuels, it can be implemented as in the past.

[0120] The deodorization system and deodorization method of the present invention can deodorize the odor by burning the remaining raw material of the coating liquid and / or the remaining coating liquid. By using the remaining raw material and / or the remaining coating liquid as a combustion material, the amount of fossil fuel used can be reduced compared to the conventional method of using fossil fuel to deodorize the odor. Therefore, the cost required for deodorizing the odor can be suppressed compared to the conventional method, and it can also contribute to the reduction of CO2 emissions.

[0121] [Second embodiment]

[0122] In general factories, there are often a plurality of buildings equipped with facilities including coating devices on a site.

[0123] In the above-mentioned first embodiment, the case where one deodorizing furnace 5 is installed corresponding to one building B is exemplified, but the present invention is not limited to this.

[0124] For example, Figure 8 As shown, when there are multiple (two for convenience in the example shown in the figure) buildings with equipment 2 in the same land, for example, the odors recovered from the equipment 2 of multiple buildings B-1 and B-2 can be collected and then deodorized in the deodorizing furnace 5.

[0125] In the first embodiment, the remaining raw material in the coating device 1 of the equipment 2 of the building B is used as the remaining raw material for preparing the combustion material for burning the odor recovered from the equipment 2 of the building B in the deodorizing furnace 5, but the present invention is not limited to this.

[0126] For example, Fig. 9As shown, in a case where there are multiple (two for convenience in the example shown in the figure) buildings having equipment 2 within the same site, for example, as residual raw materials for preparing combustible materials for burning odor recovered from equipment 2 of one building B-3 in a deodorizing furnace 5, residual raw materials in equipment 2 of another building B-4 can also be used.

[0127] The same is true for the remaining coating liquid. The coating liquid remaining in any one device 2 or any two or more devices 2 can be used as a combustion material.
