2. Description of the Related Art When a fluid is passed through a ceramic hollow fiber membrane, it is necessary to bundle the hollow fiber membranes into a module.
The present applicant has previously made an organic solvent suspension of alumina powder (alumina powder slurry) by centrifugal sedimentation at the end of the bundled porous alumina capillaries, removing the organic solvent, and then at the firing temperature of the alumina powder. A method of firing and bundling alumina thin tubes has been proposed (Japanese Patent Laid-Open No. 3-60475).

No other method has been found as a method for binding the ceramic porous hollow fiber membranes, but this method also has the following problems. (1) As a pretreatment for pouring the slurry of alumina powder,
It is necessary to seal the end surface of the alumina thin tube with an epoxy resin or the like, and it is necessary to perform centrifugal treatment until the slurry is dried and solidified, which takes time. (2) Since the thin tube group is bundled only at both ends of the alumina thin tube, the thin tube may be damaged if stress is applied to the central portion in the length direction of the thin tube. (3) When increasing the size of the module, it is necessary to reexamine the centrifugal force for causing the alumina slurry to wrap around the gap between the alumina thin tubes, and it is difficult to set the conditions for that purpose. Further, in this method, when considering bundling without performing centrifugal treatment, the method of injecting the alumina slurry into a cylindrical container, immersing the whole alumina thin tube therein and covering it with the alumina slurry, and solidifying is Conceivable,
The alumina thin tubes bundled by such a method increase the strength in the central portion in the length direction, but the pressure loss in the vicinity of the diametrical center of the module increases, so that it is not possible to increase the size of the module.

The ceramic porous hollow fiber membrane module according to the present invention has the following effects. (1) The modularization by bundling the ceramic hollow fiber membranes can be easily performed by using a dope liquid with a high filling of ceramic powder and firing. (2) It is possible to arbitrarily increase or decrease the number of ceramic porous hollow fiber membranes used. (3) Since the porous ceramic hollow fiber membrane is entirely covered with and retained by the porous ceramic body, there is no fear in terms of strength. Therefore, it can be safely used even in a part such as an automobile that receives a shock. (4) Since a gap space is provided between each unit cell and the filtered fluid is permeated without pressure loss, the number of ceramic porous hollow fiber membranes is increased, that is, the number of unit cells is increased. Even if the pressure is increased, the pressure loss does not become larger than the pressure loss in each unit cell, and thus it is possible to increase the size of the module without increasing the pressure loss. (5) It can be used in high temperature range, such as filtration of high temperature gas, which cannot be used with organic filtration materials. For example, when removing black smoke contained in the exhaust gas of a diesel vehicle, install this module in the muffler part and introduce the exhaust gas into the ceramic porous hollow fiber membrane, It is possible to remove black smoke.
