Detailed Description

Example 1

Referring to fig. 1 and 2, the reverse osmosis membrane element capable of improving the pH value of produced water comprises a central water collecting pipe 1 and at least one group of reverse osmosis membrane groups 2 wound on the central water collecting pipe 1, wherein a cavity 3 with a closed head end and an open tail end is arranged in the central water collecting pipe 1, calcite particles 5 wrapped by a non-woven bag 4 are filled in the cavity 3, a plurality of water through holes 6 are formed in the side wall of the central water collecting pipe 1, and a purified water outlet 7 is arranged at the tail end of the central water collecting pipe; the reverse osmosis membrane group 2 is rectangular after being unfolded and comprises a produced water diversion net 8, a first reverse osmosis membrane 9, a raw water diversion net 10 and a second reverse osmosis membrane 11 which are sequentially arranged, two transverse edges of contact surfaces of the produced water diversion net, the first reverse osmosis membrane and the second reverse osmosis membrane and a longitudinal edge far away from the central water collecting pipe are bonded and sealed through a bonding agent, the longitudinal edge close to the central water collecting pipe is open, and the front surfaces of the first reverse osmosis membrane and the second reverse osmosis membrane face the raw water diversion net; two annular grooves 12 are formed in the purified water outlet of the central water collecting pipe, and O-shaped sealing rings 13 are sleeved at the annular grooves 12; the non-woven bag 4 is matched with the cavity 3, and the length of the non-woven bag is the length from the head end of the cavity 3 to the annular groove 12 of the central water collecting pipe 1; a waterproof layer 14 is arranged on the outer side of the reverse osmosis membrane group 2, and the waterproof layer 14 is formed by winding a waterproof adhesive tape on the outer side of the reverse osmosis membrane group 2; and a Y-shaped water stop ring 15 is arranged at the position, close to the head end of the central water collecting pipe 1, on the outer side of the waterproof layer 14.

The more detailed explanation is:

raw water enters the front face of the reverse osmosis membrane through the raw water diversion net 10, purified water filtered by the reverse osmosis membrane is drained to the water through the water production diversion net 8 and then enters the cavity 3 of the central water collection pipe 1, then the purified water enters the non-woven fabric bag 4 and flows through the calcite particles 5, a small amount of mineral substances and trace elements are dissolved out, the pH value of the purified water is adjusted to be alkalescent from acidity, and finally the purified water is output through the purified water outlet 7.
