Abstract
The utility model relates to an inorganic micro filter membrane modifying device, which is characterized in that an inorganic micro filter membrane support (3) is arranged in a modifying container (2). The device is simple in structure, easy to operate and low-cost. Saturated steam environment guarantees that homogeneous reaction in membrane holes proceeds successfully. Modified reaction product is of nanometer size and equably deposits on the surface of the wall of the membrane holes. And thereby, filter efficiency of the inorganic micro filter membrane is much higher than that of the filter membranes not modified and other chemical properties of the membrane are also remarkably improved.
Description
Technical field
The utility model relates to the inorganic micro filtering technology field of membrane materials, is specifically related to a kind of device that is used for the inorganic micro filtering membrane modification.
Background technology
Membrane technology is that twentieth century enters industrial circle the sixties, because its energy consumption is low, preparation process is simple, treating capacity is big, has obtained application more and more widely since the seventies in each industrial circle and research.Inorganic micro filtering membrane requires to have good microstructure, suitable pore size and distribution, higher porosity and mechanical strength, convection cell should have high mass transfer permeation flux etc., thereby is vital to the modification of inorganic micro filtering membrane.By introducing some specific material, form modified coating, to improve the performance of fenestra wall surface, enable to satisfy the requirement that micro-filtration, ultrafiltration or gas separate, become the research focus in the membrane technology field.
In the prior art, make the device structure complexity of fenestra wall surface formation modified coating, and the inaccessible desirable technique effect of coating that forms.
Summary of the invention
The utility model provides a kind of and has made the inorganic micro filtering membrane hole wall surface form oxide coating by homogeneous precipitation method at the deficiency of present inorganic micro filtering membrane modification technology, thus the device that inorganic micro filtering membrane is carried out modification.This apparatus structure is simple, and modified effect is good.
The technical solution of the utility model is: a kind of device that is used for the inorganic micro filtering membrane modification is characterized in that the inorganic micro filtering membrane carriage places in the modification container.
Description of drawings
Fig. 1 is the structural representation of inorganic micro filtering membrane reforming apparatus.
The specific embodiment
Now in conjunction with the accompanying drawings the structure of inorganic micro filtering membrane reforming apparatus is described in detail:
As shown in Figure 1, the reforming apparatus of a kind of inorganic micro filtering membrane of the present utility model comprises sealing modification container 2 with cover, micro-filtration membrane carriage 3 is arranged in the container 2, the micro-filtration membrane 1 for the treatment of modification places on the carriage 3, be added with an amount of water 4 in the container 2, can place drying box, water-bath after container 2 seals or adopt the external heating jacket that directly links to each other to heat with container 2.After the heating, modified-reaction carries out under the saturated vapor environment, prevented the volatilization of water and precipitation from homogeneous solution agent configurational ion in the modified solution, thereby guaranteed that precipitation from homogeneous solution is reflected at carrying out smoothly in the fenestra, product is deposited on the fenestra wall surface and forms modified coating.
The utility model compared with prior art has following advantage and effect:
(1) reforming apparatus is simple, easy operating, and cost is low, and the saturated vapor environment has guaranteed that homogeneous reaction carries out smoothly in inorganic fenestra;
(2) modified-reaction product crystal grain is the nano-scale size, and uniform deposition is at the fenestra wall surface, and existing inorganic micro filtering membrane is obviously improved water filtration efficient, other chemical property of film also be improved significantly.
