Description of the invention [Technical field of the invention] The present invention relates to a fountain solution circulation processing device and a fountain solution circulation processing method for a fountain solution used in lithographic printing. [Prior art] Lithography In printing, it is very important to manage a high-quality printing fountain solution. Impurities such as paper dust, dust, oil, or powder are mixed into the fountain solution during printing. In this way, in order to purify the fountain solution containing impurities, the fountain solution circulation device is connected to the water tank of the printing equipment. The dampening solution circulation device recovers the dampening solution in the water tank and filters it with a porous filter material such as a sponge filter to generate fresh dampening solution and supply it. At the same time, because the bacteria in the air invade the dampening potion, even if the dampening potion circulation device is used to continuously use the dampening potion, malodor will occur. Therefore, in order to prevent the malodor generated by this bacteria, a UV lamp was installed in the fountain solution circulation device, and the bacteria of the fountain solution were eliminated by irradiating ultraviolet rays. However, in general, the regulator used in the fountain solution circulation device, its? Ben Yeque is about m "-lies in the collection of Hei Cui Cui dampening solution circulation device. The filtered dampening solution will become cloudy and have poor transparency. Therefore, it is difficult to say that the light of the ultraviolet lamp cannot be sufficiently spread in the dampening potion. It can hardly be said that it can fully exert the bactericidal effect produced by the irradiation of ultraviolet rays. -5- (2) (2) 200302174 Therefore, in the present invention, there is provided a fountain solution circulation treatment device and a fountain solution circulation treatment method which can improve the transparency of the fountain solution and can be sufficiently covered with ultraviolet rays from an ultraviolet lamp or the like to improve the sterilization effect. [Content] [Invention of the invention] The fountain solution circulation treatment device of the present invention belongs to the circulation treatment device for the fountain solution of circulation and purification treatment of the fountain solution used in lithographic printing, and lies in the circulation path of the fountain solution. On the way, a potential absorption suction device using a zeta potential suction function is provided, and further, a UV irradiation device for irradiating ultraviolet rays to a dampening solution is provided at the rear stage of the potential suction filter device. Meanwhile, the dampening potion circulation treatment method of the present invention belongs to the circulation and purification process of the dampening potion circulation treatment method used in the lithographic printing of the dampening potion, and the filtering dampening potion is irradiated with a zeta potential absorption filter and then irradiated. Ultraviolet rays are characteristic. Particles in impurities in paper powder 'dust, oil, or powder contained in fountain solution, in other words, particles with a diameter of about 0.4 to 1 0 // m that make the fountain solution turbid and affect its transparency, cannot be used. It is removed by a filter made of a general porous filter material. However, since these microparticle components are connected to | to indicate a negative potential, they can be absorbed by the positive zeta potential and removed. Therefore, the dampening solution circulation treatment device of the present invention uses a potential adsorption filter device to suck and remove the particles contained in the dampening solution into -6-(3) (3) 200302174 copies of "in other words" can be borrowed By absorbing and removing the ingredients mixed in the dampening potion to improve the transparency of the dampening potion, the ultraviolet rays irradiated by the ultraviolet device in the subsequent stage are formed to sufficiently spread the dampening potion, and the sterilizing effect by ultraviolet rays can be improved. At the same time, this dampening potion is not turbid after long-term use, so it can be reused without being discarded. This can reduce the running cost of dampening potion. At the same time, by using this refined fountain solution for lithographic printing, the quality of printing can be improved. [Embodiment] [Embodiment of the invention] Fig. 1 is a system diagram of a fountain solution circulation treatment device according to an embodiment of the present invention. The fountain solution circulation processing device 1 according to the embodiment of the present invention introduces fountain solution used in a lithographic rotary printing press from the introduction port 8a (upstream side), and then circulates through the discharge port 8b (downstream side). Roads 9a, 9b, 9c, 9d. Between the circulation paths 9a, 9b, between the circulation paths 9b, 9c, and between the circulation paths 9c, 9d, respectively, a pump device for forced circulation dampening potion 4 is arranged, and a potential suction using a zeta potential suction function is provided. A filter device 2 and an ultraviolet irradiation device 3 which irradiates ultraviolet rays to a dampening solution are provided. Further, the dampening solution circulation processing device 1 is equipped with a siphon filter-device. The device m and the ultraviolet irradiation device 3 are more external, and have a circulation path 9b as a detection introduction port 8a side and a guide port 8b. The differential pressure transmitter 5 of the differential pressure detection device that sends out a detection signal after the differential pressure between 9 and 9d; and issues an alarm in response to the detection level of the detection signal of the differential pressure transmitter 5 (4) ( 4) The rotating light 6 of the alarm device of 200302174. FIG. 2 is a cutaway perspective view of a portion of the potential suction tube contained in the housing of the potential suction filter device 2 shown in FIG. 1. The potential absorbing filter device 2 houses a potential absorbing cartridge 20 in a housing so that the potential absorbing filter can be replaced. The potential suction tube 20 is mainly a cell formed by holding a medium 21 made of resin and cellulose, a polypropylene separator 22, and a cap 23; a polypropylene seal ring 24—side The polypropylene core 25 is used for assembly. Generally speaking, after the potential difference is generated at the interface of heterogeneous contact, the potentials generated in the electrical double layer at the particle interface are the part that does not play a dynamic role (fixed layer) and the part that plays a dynamic role ( Diffusion layer). In different phases, only in the case of relative motion, the electrical phenomenon that occurs at this interface is called the interface electrokinetic phenomenon, and the potential that exists there is called the interface electrokinetic or zeta potential. The zeta potential, which is the same as the Tyndali phenomenon or Brownian motion, is a physical phenomenon formed by the characteristics of microparticles. Generally speaking, microparticles or microorganisms in a liquid have no negative potential. Particles such as ink, paper powder, or oil contained in fountain solution also indicate a negative potential. Correspondingly, the potential attracts the medium 2 1 in the filter device 2 because it has a positive zeta potential characteristic. Absorption and removal of ordinary membranes, Qin qi can not slap some ceremonial particles. Jieji's shoulder-position effect removes particulates without the need to pressurize the fountain solution through the potential absorption filter device 2. In addition, the dampening solution circulation treatment device 1-8 in this embodiment (5) (5) 200302174 uses the differential pressure transmitter 5 to detect the differential pressure between the circulation paths 9 b and 9 d, and when When a differential pressure exceeds 2 · 2 kg / cm 2, the rotating lamp 6 is turned on and an alarm is issued. The medium 2 1 in the potential suction filter device 2 is because the differential pressure suddenly rises when the potential suction force reaches a critical point, and the operator is notified to replace the potential suction filter by detecting the rise in the differential pressure. The timing of the device 2 can prevent the flow of the dampening potion from exceeding the set value. Fig. 3 is a perspective view of the ultraviolet irradiation device 3 shown in Fig. 1. The ultraviolet irradiation device 3 shown in FIG. 3 is provided in the middle of the hollow valve body 30 having an inlet flange 31 connected to the circulation path 9c at both ends and a hollow valve body 30 connected to the guide port 32 of the circulation path 9d. Equipment 33. The ultraviolet irradiation device 33 is inserted into the ultraviolet lamp 34 to the valve body 30, and then irradiates the ultraviolet rays to the ultraviolet rays passing through the valve body 30. The irradiation equipment 33 can be detached from the valve body 30, and the ultraviolet lamp 34 and the like can be replaced regularly for maintenance. The dampening solution circulation treatment device 1 configured as described above is connected to the water tank 12 of the lithographic rotary printing machine as shown in FIG. 1. Here, the water tank 12 constitutes a part of the dampening section 11 provided on the plate 16 of the lithographic rotary printing press, and the dampening section 11 includes a plurality of water fountains 12 in the order of the water tank 12 to the plate 16. Rollers 1 3, 1, 4, 1 5. The dampening solution circulation processing device 1 is connected to the connection paths 10a, 10b, and 10a by the water tank 12. The connection path 10a is connected to the introduction port 8a of the fountain solution circulation processing device 1, and the connection path 10b is connected to the guide port 8b. In the above configuration, the water tank 12 is inside The dampening solution is forcibly input into the circulation path 9a by the pump device 4. The dampening solution in the water tank 12 is introduced into the circulation path 9a from the introduction port 8a through the connection path 10a, and then is introduced into the potential suction filter device 2 through the (6) (6) 200302174 circulation path 9b. The potential suction filter device 2 uses the zeta potential suction function to suck and remove particulate components such as ink, powder paper, or oil contained in a fountain solution. In this way, the potential absorption works are used to adsorb and remove the fine particle components, and it is possible to remove the fine particle components without forming a fountain solution that is pressurized to the potential absorption device 2. Further, the dampening solution introduced into the ultraviolet irradiation device 3 through the circulation path 9c is sterilized by the ultraviolet light emitted by the ultraviolet lamp 34, and then returned to the water tank 12 using the circulation path 9d and the connection path 1 Ob . As described above, the dampening solution circulation treatment device 1 according to this embodiment absorbs and removes the particulate components contained in the dampening solution using a potential suction filter device 2 and then irradiates the ultraviolet rays with the ultraviolet irradiation device 3 to sterilize. In other words, the potential absorption filter device 2 is used to absorb and remove the moisturizing potion, so that the transparency of the moisturizing potion can be improved, so that the ultraviolet rays irradiated by the ultraviolet irradiation device 3 in the subsequent stage can be spread throughout the moisturizing plate. Potion produces a bactericidal effect that can increase ultraviolet rays. Therefore, the dampening solution circulation treatment device 1 of this embodiment uses a potential suction filter device 2 and an ultraviolet irradiation device 3 prepared in the middle of the circulation paths 9a to 9d to maintain a predetermined flow rate, thereby reducing biochemical requirements. The amount of oxygen (B0D), chemical oxygen demand (COD), n-hexane extract index, and Luzhu Biomedical HS +, etc., and further prevent the sterilized potion from being cloudy after long-term use. It can be recycled without being treated as waste. As a result, waste liquid of dampening solution does not occur, and it is not necessary to entrust outsourcing. (7) 200302174 Disposal of waste liquid results in a reduction in running cost of dampening solution used in lithographic printing. At the same time, by using this refined fountain solution to treat lithographic printing, the printing quality can be improved. [Industrial Applicability] As described above, the fountain solution circulation treatment device and the fountain solution circulation treatment method of the present invention are suitable for recycling the fountain solution used in lithographic printing.
