Description of the invention (1) [Background of the invention] (Field of invention) (Please read the notes on the back before filling out this page) This invention is a fountain solution for processing fountain solutions used in offset printing. Circulation treatment device and method for circulation treatment of dampening solution. [Previous technology] In offset printing, the management of fountain solution is very important. The fountain solution circulation device is to supply the clean fountain solution with a predetermined concentration of each component to the medicine tank of the printing unit at a certain flow rate and temperature, and recover the fountain solution through the medicine tank, and then regenerate it. Make fresh fountain solution for the potion. In recent offset printing presses, continuous dampening solution circulation devices are often used. In order to stabilize the pumping, isopropyl alcohol (I P A), an organic agent, is used. Since this I p A is added to the fountain solution, the surface tension of the fountain solution is reduced, and the non-lined parts can be uniformly wetted with a small amount of fountain solution. That is, the water quality of the IPA layout is very good, and the printing quality is maintained. In addition, from the aspect of labor safety and health, the printing of I P A by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs has its problems. It is necessary to limit the use to a minimum or implement a moisturizing solution without I P A. Regardless of the management of any of these fountain solutions, it will become even more important. Fig. 5 is a system diagram of an example of a conventional dampening circulation medicine device 101. In FIG. 5, the fountain solution is mixed with a fountain solution mixing device 102, and the original solution of the fountain solution is mixed with water, methanol, etc. at a correct ratio, and a new fountain solution is sent to the fountain solution circulation device 101. Dampening potion circulation device This paper size is applicable to Chinese National Standard (CNS) A4 (210 X 297 mm) -4- 496752 A7 ____B7 V. Description of the invention (2) 1 〇1 is the potion tank from the printing unit 1 0 The contamination from the fountain solution 7 returned by 3 is removed in the filtering device 104, and then returned to the medicine tank in the fountain solution circulation device 101 (not shown in the figure). When the amount of dampening potion in the potion tank is reduced, a new dampening potion is replenished from the dampening potion mixing device 1 0 2 by a float ball valve 105. The dampening potion in the potion tank is maintained at a set temperature by a cooling device (not shown). Methanol temperature control 106 is to control the concentration of methanol which is easy to evaporate. In the methanol concentration-controlling device 106, the dampening solution in the medicine tank is continuously sent into the usual way. The hydrogen ion concentration is detected by monitoring PΗ 値 in the water, and the necessary amount of methanol is replenished. The concentration of methanol is maintained in the version of the potion. It is also necessary to manage the use of a corrosive liquid as an alternative to IPA. The temperature and concentration of the dampening solution should be kept constant in concentration and evaporation rate. In the case of methanol, the concentration is controlled by a hydrometer. On the one hand, in the case of using corrosive liquid as a substitute for IPA, the conductivity of the dampening potion is printed by the consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Another change, love is empty.

The dyeing place is described in 4 places or the medicine is often on the ο 3 liquid version of the special, 1 ο fullness of the holding is set to 1 rot in the water, but installed in the tank with medicine and other examples of water filtration version of the oil mist !! hi order --------- line! · (Please read the precautions on the back before filling this page) This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) -5- 496752 A7 _ ________________ B7 V. Description of the invention (3) (Please Read the precautions on the back before filling out this page) to remove it. Therefore, its ability to remove impurities depends on the thickness of the filter, and usually only removes impurities up to 100 // m. It is assumed that the mesh size in the filtration is reduced to improve the removal ability of impurities, because the pressure of the dampening potion will increase through the void layer, and the dampening potion will not be circulated at the set flow rate. When the liquid circulation fountain solution cannot be used at the predetermined flow rate, the normal function will be lost and the printing quality will be low. In addition, if the mesh of the filter is too thin, it is necessary to clean the filter frequently because the mesh is blocked by impurities. In addition, in such a conventional dampening circulation device 101, the dampening solution was circulated and used for about 2 to 3 months due to the limitation of its filtering ability. Due to the soiling and failure of the dampening solution, it could not be used as a dampening solution Degree of potion. Here, although the fountain solution needs to be replaced, in the past, only the biochemical oxygen requirement (BOD), chemical oxygen requirement (COD), and n-hexane in the waste liquid of the fountain solution were physically filtered. And suspended substances (printed by SS from the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs) will not pass the legal drainage standards. Therefore, the fountain solution waste liquid will become industrial waste and it cannot be discharged into rivers and the like. As a result, specialized operators must be entrusted to dispose of the waste liquid, which will cost a lot of money. Here, the present invention provides that it is possible to remove the components of BOD, COD, n-hexane, and SS from the fountain solution without pressurizing the fountain solution. Dampening circulation processing device and method for recycling dampening solution. -6-This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) 496752 A7 _ B7 V. Description of the invention (4) [Summary of invention] (Please read the notes on the back before filling in this Page) The fountain solution of the present invention is a fountain solution circulation treatment device for the purification treatment of the fountain solution used in offset printing. It is characterized in that it is used on the way to circulate the fountain solution. Z-potential adsorption filter device, and activated carbon filter device using activated carbon. --Line Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Because the particles of ink, paper powder or oil contained in fountain solution generally show no negative potential, the potential in the potential absorption filter device The suction filter has a positive Z-potential and can absorb fine particles that cannot be removed by a filter formed by a generally porous filter material. In addition, according to this potential absorption function, the particulate component can be reduced without pressurizing the fountain solution passing through the potential absorption filter. In addition, the dampening solution can be decolored and deodorized by passing through a live or charcoal filter. That is, it can maintain the predetermined flow rate and reduce the components of B.OD, CoD, (n-hexane 値) 値 and S S., and the decolorizing and deodorizing fountain solution can be used for a long period of time without waste. Can be reused. As a result, no waste liquid of dampening solution is generated, because the external liquid waste treatment does not need to be commissioned, so the running cost of dampening solution for offset printing can be reduced. In addition, the use of such refined fountain solution for offset printing can also improve printing quality. Especially in the circulation path, a potential suction filter is installed on the upper side and an activated carbon filter device is installed on the lower side to constitute 'the particles of ink, paper powder or oil contained in the fountain solution are absorbed by the potential. After the filtering device is removed, the life of the activated carbon filter in the activated carbon filtering device can be greatly extended by passing through the activated carbon filtering device. This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 Gongchu) Printed by the Employees' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 496752 A7 B7 V. Description of the invention (5) And it is better to have the introduction of a detection loop A differential pressure detection device for the differential pressure between the port and the outlet port side, and an alarm device that issues an alarm corresponding to the detection result of the differential pressure detection device. By detecting the difference between the inlet side and the outlet side of the circulation path, an alarm is issued, and the operator is informed of the exchange time of the potential filter and the activated carbon filter, which can prevent the flow rate of the dampening solution from exceeding the set value. The operator can simply manage the dampening potion. Here, it is desirable that the differential pressure between the inlet port side and the outlet port side of the circulation path is 2 · 2 k g / cm 2 or less. This makes it possible to make the most effective use of the potential absorbing filter device and the activated carbon filter device as the fountain solution flow rate, and it is possible to easily maintain the printing quality. In the case of exceeding 2 · 2 k g / cm 2, the purification treatment cannot be performed sufficiently because the mesh of the potential adsorption filter or the activated carbon filter device is blocked. The dampening potion circulation treatment method performed by a water circulation processing device of the present invention is characterized in that the dampening potion circulation treatment method for circulating and purifying the dampening potion is used in offset printing, and the dampening potion is passed through a Z-potential The suction filter is filtered, and then the activated carbon filter is filtered and recycled. In this way, particles such as ink, paper powder, or oil contained in the fountain solution can be removed by Z-potential adsorption, and then decolorized and refined by activated carbon, so that the fountain solution can be used semi-permanently.

Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, a potential difference will generally occur at the out-of-phase contact interface. Among the potentials due to the electrical double layer in the particle boundary, there are parts that do not act (fixed layer) and parts that act ( Diffusion layer). In the case where there is only relative movement between different phases', the electrical phenomenon caused at the interface is called the interface kinetic phenomenon, and the potential existing here is called the interface kinetic potential or Z-potential. Z potential system is the same as Tyndall (scattering) phenomenon or Brownian motion. It is a physical phenomenon due to the characteristics of fine particles. Generally, particles or microorganisms are in the liquid. 11----: ---, ------ II __ (Please read the precautions on the back before filling out this page) Line-This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 496752 A7-B7 V.
