Background
When a nanofiltration membrane element or a reverse osmosis membrane element (hereinafter, simply referred to as a membrane element) is used, a plurality of membrane elements are required to be sequentially filled in a pressure container along a water flow direction for use in order to improve the filtration effect. At present, the pressure container is mostly of a circular tube type, two grooves are annularly arranged on the inner tube wall of the pressure container, and the two grooves are respectively positioned at two ends of the pressure container; the two ends of the pressure container are respectively provided with an end cover which is tightly attached to the membrane element, the arrangement of the groove is convenient for the end covers to be tightly clamped on the pressure container, and the end covers are used for forming a closed space with the pressure container, so that the membrane element is prevented from moving when the membrane element works, and the pressurized water body is prevented from leaking out of the membrane element; a water inlet communicated with the water inlet pipeline is arranged on one end cover of the pressure container, and a water outlet communicated with the water drainage pipeline is arranged on the other end cover; the water inlet pipeline is connected with a first membrane element arranged in the pressure container along the water flow direction through a water inlet, and the water discharge pipeline is connected with a last membrane element arranged in the pressure container along the water flow direction through a water discharge port; and a water outlet for discharging purified water is arranged on the side wall of the pressure container, and the water outlet is connected with purified water collecting equipment through a water outlet pipeline.
A common replacement scheme when regularly replacing a used membrane element is as follows: firstly, detaching a water inlet pipeline, a water drainage pipeline and end covers at two ends of a pressure container; secondly, selecting a rigid long rod, and wrapping soft materials such as cloth, sponge and the like at the operation end of the long rod; then, an operator holds the long rod by hand, the operating end of the long rod extends into the pressure container, and all the membrane elements are sequentially ejected out of the pressure container; then, cleaning the pressure container, and sequentially filling a plurality of new membrane elements into the pressure container along the water flow direction; and finally, connecting the water inlet pipeline and the water discharge pipeline with the membrane elements at two ends of the pressure container respectively along the water flow direction, and then tightly clamping the end covers at two ends of the pressure container on the pressure container. According to the replacement scheme, the membrane element can be put into use after a new membrane element is assembled in the pressure container. However, the use of the above replacement scheme is prone to the following drawbacks:
1) when the membrane element is used in the pressure container, in order to ensure the flow of the water body, the water body flowing into the membrane element needs to be pressurized, the pressurized water body flows in the membrane element for a long time, so that the firm sticking between the membrane element and the inner pipe wall of the pressure container is easily caused, the membrane withdrawing difficulty is increased, the membrane element is not conveniently and smoothly ejected out of the pressure container by singly using the rigid long rod, and the membrane withdrawing efficiency is reduced.
2) The membrane element is ejected out of the pressure container by the rigid long rod, so that even if soft materials such as cloth and sponge are wrapped at the operation end of the long rod, the membrane element is hardly damaged, and the reuse rate of the membrane element is reduced.
