Abstract

Apparatus for treating liquid, for example for ultrafiltration, comprising an elongate housing containing a removable insert, such as an annular array of filter tubes. Liquid to be treated flows through the centre of the annular array from an inlet and is reversed and returned through the filter tubes to emerge at an outlet at the same end of the array as the inlet. A plurality of housings can be interconnected in series connection. <IMAGE>

Description

Liquid Treatment Apparatus The present invention concerns apparatus for the treatment of liquids, for example ultrafiltration and ion exchange apparatus.
According to the present invention apparatus for the treatment of liquids includes an elongate housing containing a removable insert, one end of the insert having an annular chamber sealingly engageable in the housing and having ports cooperable with inlet and outlet ports in the housing, the inlet port communicating directly with a central passage extending through the insert such that a liquid introduced at the inlet flows along the passage to the end of the insert remote from the annular chamber and is then reversed to flow through the insert to enter the annular chamber and emerge at the outlet port.
The insert can comprise an annular array of filter tubes and the housing can be formed with a further outlet or outlets in communication with the region thereof about the array of tubes. Alternatively, the insert can comprise an ion exchange unit or column.
Preferably the annular chamber is provided with a harness seal to provide an effective seal at the inlet and outlet ports.
The housing can comprise a cylindrical member extending from an opening in a support platform, the opening being closed by a removable plug. For the treatment of radioactive or other toxic liquids the platform and plug are formed from an appropriate shielding material.
A plurality of units can be connected together in a desired arrangement, for example, in series connection with the outlet from one housing leading to the inlet of a further housing, a pump being provided to circulate liquid to be treated through the assembly.
When mounted beneath a support platform each insert can be withdrawn and replaced through the opening in the platform upon removal of the plug. The operation can be performed using a maintenance flask which can be moved and located in position above an opening in the platform by means of an overhead hoist.
The invention will be described further, by way of example, with reference to the accompanying drawings; in which:- Figure 1 illustrates, in section, an embodiment of an ultrafiltration unit and a housing; Figure 2 is a perspective view of the unit; Figure 3 shows the filtration unit installed for use.
An ultrafiltration unit in Figure 1 comprises a cylindrical housing 1 containing a removable insert 2.
The insert 2 comprises an annular chamber 3 carrying an elongate annular array of tubular filters 4, the ends of the filter tubes at one end of the array communicating with the chamber 3. The opposite ends of the filter tube open into a compartment 5 which is open to a central passage 6 extending to the chamber 3. The filter tubes 4 are housed within concentric cylindrical walls 7, 8 and the outer wall 7 is provided with openings 9 adjacent its ends.
An inlet port 10 in the housing 1 communicates directly with the passage 6 through a conduit 11 which extends across the chamber 3. An outlet port 12 in the housing communicates directly with the chamber 3. The chamber 3 is provided with a seal 20, preferably a harness seal, to effect seal at the inlet and the outlet ports. Conveniently, the end of the housing 1 is formed with a slight taper and te exterior of the annular chamber 3 has a matching taper to slidingly fit within the end of the housing.
In use, a liquid to be filtered is pumped through the inlet port 10 to flow along the central passage 6 to the compartment 5. The flow direction is then reversed and the liquid travels through the filter tubes 4 into the chamber 3 and emerges through the outlet port 12.
The walls of the filter tubes are chosen to be permeable to a component part of the liquid flow with the result that this component issues through the openings 9 in the outer wall 7 of the array into the housing from which it is removed through a further outlet or outlets.
Figure 2 is a perspective view of the insert showing a pintle 14 on the chamber 3 whereby the insert can be lifted and lowered by means of an overhead hoist.
Figure 3 is a perspective, cut-away illustration of the filtration unit when installed for use. For use with radioactive or toxic liquids the unit and associated pipework is located behind shielding walls. In Figure 3, the housing 1 comprises a cylindrical member 15 extending from an opening in a shielding platform 16 to a tank 17 beneath the platform to receive and collect filtrate.
The opening in the platform 16 is closed by a removable plug 18 of shielding material. An inlet pipe 19 conveys liquid to be treated to the unit and a plurality of the units can be installed in series connection above the tank 17. The liquid is pumped through the units by a recirculation pump.
The units can be mounted and connected together in other desired arrangements. For example, instead of being mounted above the tank 17 the filtrate can be drawn off through conduits coupled to ports in the housings.
In an alternative arrangement the filter tubes can be replaced by a column of ion exchange material. A pipe in communication with the inlet extends through the material to direct inlet flow to be treated to the end of the column remote from the annular chamber. The liquid leaving the pipe flows through the column and is treated before emerging into the chamber and out through the outlet.
