Description

  The present invention relates to a water treatment filter module including a membrane used for water treatment, and a water treatment filter device including the water treatment filter module.

  Membrane separation technology represented by so-called solid-liquid separation, which separates suspension in water and water, has attracted attention in recent years.

  For example, a reverse osmosis membrane is used when desalinating seawater. This separation method using a reverse osmosis membrane has higher energy efficiency than, for example, a distillation method that is another separation method employed when desalinating seawater. In addition, microfiltration membranes, ultrafiltration membranes, nanofilters, and the like are also used in the manufacturing process of foods and pharmaceuticals in which a substance to be treated is easily affected by stress such as heat. In addition, in water treatment and sewage treatment, introduction of membrane separation technology using a microfiltration membrane, an ultrafiltration membrane, or the like is progressing.

  The type of separation membrane can be classified by the separation hole diameter, material, shape, and the like. For example, a separation membrane that prevents passage of particles of about 0.1 μm to several μm is called a microfiltration membrane. A separation membrane that prevents passage of particles of about 2 nm to 0.1 μm is called an ultrafiltration membrane. Furthermore, a separation membrane that prevents passage of particles smaller than 2 nm is called a nanofiltration membrane.

  The material of the separation membrane can be broadly classified into three types: organic polymer, metal, and ceramic, and organic polymer membranes that are relatively inexpensive and highly versatile are the mainstream, but heat resistance, environmental resistance, and repeated use Metal films and ceramic films having excellent resistance and the like are also used depending on applications.

  As a general merit of the membrane separation technique, there is an advantage that the target substance can be separated by controlling the pore diameter of the membrane material in addition to the above-mentioned high energy efficiency.

  Moreover, as a general demerit of the membrane separation technology, for example, when purifying a large volume of water, the occupied volume of the separation membrane increases in proportion to the amount of water treated. This is because the amount of treatment in the separation membrane depends on the surface area of the separation membrane.

  Therefore, the surface area per unit volume in the separation membrane has been improved. For example, the surface area is increased by devising the shape of the separation membrane. In organic polymer membranes, flat membranes have traditionally been used well, but in recent years, the demand for hollow fiber membranes has increased due to the large surface area per unit volume. There are two main types of metal films, wire mesh and powder sintering, both of which are used after being processed into a cylindrical or pleated shape. Many ceramic membranes are used after being processed into a cylindrical shape, a cylindrical shape, or a honeycomb shape (for example, see Patent Document 1).

For example, when the water treatment filter module 10 is used under conditions where corrosion resistance and heat resistance are required, a metal material such as stainless steel or titanium, or a ceramic material excellent in corrosion resistance or heat resistance is used. It is preferable to do.

  Further, the thickness of the first flat plate member 20 is formed to be about 50 μm to 1000 μm in order to reduce the thickness of the water treatment filter module 10 and increase the membrane surface area of the filter 40 with respect to the entire volume of the water treatment filter module 10. It is preferred that

  For example, when the first flat plate member 20 is made of metal, the recess 23 of the first flat plate member 20 can be formed by etching, machining, pressing, or the like. Further, when the first flat plate member 20 is formed of a ceramic material, the concave portion 23 of the first flat plate member 20 can be formed by machining or the like.

It is preferable to be in the range. That is, the linear expansion coefficient of the joining member is in the range of 0.9 to 1.1 times the linear expansion coefficient of the first flat plate member 20. For example, when stainless steel is used as the first flat plate member 20, the linear expansion coefficient (20 ° C.) of stainless steel is 14.7 × 10 ⁻⁶ / K. It is set in the range of ^{.2 × 10 -6 /K~16.2×10 -6 / K} . By setting it as this range, it can prevent that a junction part peels or a crack arises in a junction part.

The material which comprises the 2nd flat plate member 30 can be selected from an above-described material suitably according to the environment where the filter module 10 for water treatment is used. For example, when the water treatment filter module 10 is used under conditions where corrosion resistance and heat resistance are required, a metal material such as stainless steel or titanium, or a ceramic material excellent in corrosion resistance or heat resistance is used. It is preferable to do.

  The thickness of the second flat plate member 30 is formed to be about 50 μm to 1000 μm in order to reduce the thickness of the water treatment filter module 10 and increase the membrane surface area of the filter 40 with respect to the entire volume of the water treatment filter module 10. It is preferred that Further, the height of the protrusion 33, that is, the height of the liquid flow path 32 is such that the second flat plate member 30 is thin while suppressing pressure loss in the liquid flow path 32 when the liquid is guided to the discharge port 31. Therefore, it is preferably formed to have a thickness of about 25 μm to 900 μm.

  For example, when the second flat plate member 30 is made of metal, the liquid flow path 32 and the protrusion 33 can be formed by etching, machining, pressing, or the like. Moreover, when the 2nd flat plate member 30 is formed with the ceramic material, the liquid flow path 32 and the projection part 33 can be formed by machining. Moreover, when the 2nd flat plate member 30 is formed with the resin material, the liquid flow path 32 and the projection part 33 can be formed by machining, press molding, etc. FIG. Moreover, when the resin material is a thermoplastic resin, the second flat plate member 30 may be formed by using injection molding.

  The first flat plate member 20 and the first flat plate member 20 are joined together by joining the outer peripheral edge of the other surface 20b of the first flat plate member 20 and the outer peripheral edge of the first surface 30a of the second flat plate member 30 with a joining member. The two flat plate members 30 are airtightly bonded so that the liquid does not flow out from the outer peripheral portion.

Even when the pressure difference between the one surface side and the other surface side is large, the filter 40 can be prevented from being deformed to the liquid flow path 32 side.

  Further, the first flat plate member 20, the second flat plate member 30, and the filter 40 can be formed of thin flat plate members to achieve a reduction in thickness. Further, by reducing the thickness of the water treatment filter module 10, the membrane surface area of the filter 40 with respect to the entire volume of the water treatment filter module 10 can be increased. Thereby, the water treatment capability in the filter module 10 for water treatment can be improved.
