For example, the first component 1 and the second component 2 are arranged in a manner of being attached to each other, the filter membrane component is located between the two components, the three components can be tightly fixed through bolts, and can also be fixed through other modes, but the fixing mode needs to be high temperature resistant, namely, the tight connection of the three components can still be realized under the high temperature condition. The first assembly 1 is provided with a mixed fluid flow guiding channel 3 and a first fluid flow guiding channel 4, the mixed fluid enters the purifying unit through the mixed fluid flow guiding channel 3 to complete the subsequent purification, that is, the inlet end of the mixed fluid flow guiding channel 3 is the inlet end of the mixed fluid, and the mixed fluid flow guiding channel 3 is used for introducing the mixed fluid. The mixed fluid enters the purifying unit through the mixed fluid flow guide 3, and then is purified and separated through the filter membrane assembly, so that the second fluid in the mixed fluid is separated out, and only the first fluid is left, namely the mixed fluid is formed by the first fluid and the second fluid, the second fluid in the mixed fluid is separated out through the filter membrane assembly, so that the second fluid passes through the filter membrane assembly and enters the second assembly 2 of the purifying unit, the first fluid is prevented from entering the second assembly 2, and the first fluid is continuously left in the first assembly 1. The second component 2 is provided with a second fluid flow guide 5, and a second fluid entering the second component 2 area through the filter membrane component directly enters the second fluid flow guide 5 and enters a second fluid channel 7 through the second fluid flow guide 5.

As can be seen from the above, the embodiment of the present application has the advantages that the purifier has a simple structure, so that the purifier can be made smaller and smaller, the overall manufacturing process is relatively simple, and the purification of the mixed fluid can be realized only by arranging the first assembly 1, the second assembly 2 and the filter membrane assembly having different fluid channels. In addition, because the purifier is formed by combining at least one purifying unit, a user can flexibly increase or decrease the purifying units according to actual needs, for example, when the flow rate of the mixed fluid is larger, the purifying units can be increased, and when the first flow rate is smaller, the purifying units can be decreased, so that the purifying effect is ensured.
