Description

Filter material structure and washing filter device using same Technical Field The invention relates to a filter material structure and a water washing filter device applied to the same, in particular to a filter material structure and a filter device capable of improving gas filtering efficiency. Background The development of carbon capture technologies in the prior art can be divided into two general categories, the first category is traditional carbon capture technologies, such as dry calcium oxide, alcohol amine absorption, membrane filtration, etc., which have been developed to a considerable extent due to the global need for clean zero emissions, and commercial application facilities have been developed, however, these technologies still face many challenges and limitations in practical applications. In particular, these carbon capture technologies, during operation, have potential risks to both operators and the environment, as the carbon dioxide capture carriers used therein need to be operated at high temperatures, which not only increases energy consumption, but may also present a certain chemical hazard. Moreover, these technologies typically require high equipment and consumable inputs, which are burdensome on small and medium-sized enterprises, resulting in limited feasibility in small-scale applications. In addition to conventional carbon capture techniques, the second type of carbon capture technique is a wet water wash. The method is mainly applied to some traditional industries, such as food processing and manufacturing industries, and particularly in the field of oil fume combustion treatment, a water-washing type oil fume filtering device is widely applied. These devices use water flow or water mist to purify the burnt gas, however, this type of gas treatment technology has some obvious technical drawbacks, for example, in the process of co-current downflow of the flue gas and water mist, the water mist is light in weight and is not greatly influenced by gravity, while the rising flue gas is pressurized, which results in limited reaction area and contact time between the two, and the action efficiency between the gas and water mist is reduced. In view of the above problems, the prior art proposes an improved oil mist dust washing apparatus, which is mainly improved in that the air inlet direction is changed to make the air flow direction opposite to the water flow, thereby increasing the contact area of the air and the water, however, although this technique can partially enhance the air purifying efficiency, there is a non-negligible disadvantage, firstly, since the air flows reversely, the flow resistance inside the system is significantly increased, which leads to an increase in pressure loss, thereby increasing the overall energy consumption, and the technique requires a more complicated piping system to realize the reverse flow of the air and the water, which increases not only the volume of the apparatus, but also the running and maintenance costs of the whole system. In summary, in the existing carbon capturing device, the dry capturing device has the problems of high cost, high energy consumption and potential chemical hazard, so that the dry capturing device is difficult to popularize in small and medium enterprises, and the wet washing device has poor efficiency of purifying the gas, so that the industry needs a filter material structure capable of improving the capturing efficiency of the carrier and the target gas and a washing and filtering device applied by the filter material structure. In view of the above-mentioned problems of the prior art, the present invention provides a filter structure and a water washing filter device using the same, which provides a designed porous filter structure and a multi-filtering device using the same. Disclosure of Invention An object of the present invention is to provide a filter structure, in which three porous members are connected to each other, wherein one porous member is connected to the other two porous members at an included angle, so that the contact area of the filter structure is increased. An object of the present invention is to provide a water washing filter device using the above filter material structure, which comprises a first capturing device and a second capturing device, wherein the first capturing device is communicated with the second capturing device, the first capturing device and the second capturing device respectively comprise two filter modules, and the inner sides of the two filter modules respectively comprised by the first capturing device and the second capturing device are respectively provided with a filter layer and an up-down spraying module, wherein the filter layer comprises a plurality of filter material structures, so that the filter device improves the efficiency of carbon filtration/capturing. In order to achieve the above-mentioned objects and effects, the present invention provides a filter str
