Abstract
The utility model discloses an ultrafiltration membrane component unit, which comprises: have water inlet, produce the mouth of a river, backwash delivery port and dense mouth of a river's milipore filter subassembly, its characterized in that: the concentrated water outlet is provided with two branches of a concentrated water drain pipe and a flushing water outlet pipe, the concentrated water drain pipe and the flushing water outlet pipe are respectively provided with a valve, and the pipe diameter of the flushing water outlet pipe is 1/4-1/2 of that of the concentrated water drain pipe.
Description
The technical field is as follows:
the utility model relates to a part product of an ultrafilter, in particular to an ultrafiltration membrane component unit.
Background art:
the existing ultrafilter generally comprises a plurality of ultrafiltration membrane component units, each ultrafiltration membrane component unit comprises a group of ultrafiltration membrane components with a water inlet, a water production port, a back flushing water outlet and a concentrated water port, and the water inlet, the water production port, the back flushing water outlet and the concentrated water port of the ultrafiltration membrane component in each ultrafiltration membrane component unit are connected in parallel to a system main pipe through pipelines. The ultrafilter runs for a period of time and is subjected to back flushing and forward flushing, the forward flushing refers to the drainage from the water inlet end of the ultrafiltration membrane component to the concentrated water inlet end, the forward flushing is safely considered relative to the membrane running, and the forward flushing is very necessary in the running process of the external pressure type ultrafilter because the general back flushing cannot completely flush out temporary dirt blocks, and if the flushed loose dirt blocks are flushed out without the forward flushing, the dirt blocks are adhered to the surface of the membrane once running, and the recovery degree is poor. Because the pipe diameter of the concentrated water outlet end of each ultrafiltration membrane component unit is larger, under the condition that one group of ultrafiltration membrane components are subjected to forward washing, water can be discharged from the concentrated water outlet end of the first group of ultrafiltration membrane components, and the subsequent ultrafiltration components cannot be subjected to forward washing.
The utility model has the following contents:
the technical problem to be solved by the utility model is to provide an ultrafiltration membrane component unit, which comprises: the ultrafiltration membrane component with a water inlet, a water producing port, a back flushing water outlet and a dense water port is characterized in that: the concentrated water outlet is provided with two branches of a concentrated water drain pipe and a flushing water outlet pipe, the concentrated water drain pipe and the flushing water outlet pipe are respectively provided with a valve, and the pipe diameter of the flushing water outlet pipe is 1/4-1/2 of that of the concentrated water drain pipe.
The utility model is further characterized in that:
the valves are all electromagnetic valves.
The utility model has the beneficial effects that:
because the concentrated water outlet pipe and the flushing water outlet pipe are provided with two branches, the concentrated water outlet pipe and the flushing water outlet pipe are respectively provided with a valve, and the pipe diameter of the flushing water outlet pipe is 1/4-1/2 of that of the concentrated water outlet pipe, all ultrafiltration membrane modules can be effectively cleaned when the ultrafilter is flushed in the forward direction.
Description of the drawings:
fig. 1 is a schematic structural diagram of an embodiment of the present invention.
The specific implementation mode is as follows:
the utility model is further described below with reference to the accompanying drawings:
fig. 1 is a schematic structural view of an embodiment of the present invention, and as shown in fig. 1, an ultrafiltration membrane module unit includes: the ultrafiltration membrane component 5 is provided with a water inlet 1, a water production port 2, a concentrated water port 3 and a back flushing water outlet 4, wherein the concentrated water port 3 is provided with two branches of a concentrated water drainage pipe 301 and a flushing water outlet pipe 302, the concentrated water drainage pipe 301 and the flushing water outlet pipe 302 are respectively provided with a valve 6, and the pipe diameter of the flushing water outlet pipe 302 is 1/4-1/2 of the pipe diameter of the concentrated water drainage pipe 301. In this embodiment, the valves 6 are all solenoid valves.
When the ultrafilter consists of three ultrafiltration membrane component units, the pipe diameter of the flushing water outlet pipe 302 in each group of ultrafiltration membrane components is 1/3 or less than that of the concentrated water drain pipe 301; when the ultrafilter is composed of two ultrafiltration membrane component units, the pipe diameter of the flushing water outlet pipe 302 in each group of ultrafiltration membrane components is 1/2 or less than that of the concentrated water drain pipe 301; when the ultrafilter consists of four ultrafiltration membrane component units, the pipe diameter of the flushing water outlet pipe 302 in each group of ultrafiltration membrane components is 1/4 or less than that of the concentrated water drain pipe 301; this ensures that all ultrafiltration membrane modules can be effectively cleaned during forward flushing of the ultrafilter.
The working principle of the utility model is as follows: when the ultrafilter needs forward flushing, the water generating port, the reverse flushing water outlet and the valves on the concentrated water discharge pipe 301 of the ultrafiltration membrane modules in each ultrafiltration membrane module unit are closed, and the valves on the water inlet and the flushing water outlet pipe 302 are opened to carry out forward flushing.
While the utility model has been described with respect to the foregoing technical disclosure and features, it will be understood that various changes and modifications in the above-described arrangements, including combinations of features disclosed herein either individually or as claimed, may be suggested to one skilled in the art and are to be included within the spirit and scope of the appended claims. These modifications and/or combinations are within the skill of the art to which the utility model relates and are within the scope of the following claims.
