Detailed Description
In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
Fig. 1 shows an overall structural connection diagram of a cleaning apparatus for a membrane column according to an embodiment of the present invention.
Referring to fig. 1, the present embodiment provides a washing apparatus for a membrane column, including at least one ejector 210, an air pump 220, and a washing water tank 230.
The outlet end of an injector 210 is correspondingly communicated with a membrane column 100; thus, each membrane column 100 is disposed in correspondence with one injector 210.
The air pump 220 is connected to an inlet end of the ejector 210 through an air inlet pipe 221, and the air pump 220 is used to pump air into the ejector 210.
The washing water tank 230 is communicated with the other inlet end of the injector 210 through a water inlet pipe 231, and the washing water tank 230 is used for introducing washing liquid into the injector 210.
The mode that this embodiment adopted aqueous vapor to jointly inject into the membrane column washs membrane column 100, and the bubble that can utilize aqueous vapor to jointly produce reduces the hindrance of osmotic membrane and carries out more thorough washing to the membrane column, has avoided the hindrance that the inside complicated route of membrane column 100 caused the washing simultaneously, improves the cleaning efficiency.
