Novel dish tubular reverse osmosis subassembly
Technical Field
The invention belongs to the field of water treatment equipment, and particularly relates to a novel disc tube type reverse osmosis component.
Background
The present disc-tube reverse osmosis flat-plate membrane component is basically constructed as a membrane shell, an upper flange and a lower flange at two ends of the membrane shell, a central pull rod in the membrane shell, and a membrane core formed by superposing a plurality of membranes and a flow guide plate which are arranged on the central pull rod. Usually, a water inlet is arranged at the bottom of the membrane shell, inflow water flows back and forth on the surface of the flow guide disc under the action of pressure, finally, water is produced when the water penetrates through the membrane, concentrated solution is not penetrated through the membrane, and the produced water and the concentrated solution are discharged from a concentrated solution outlet and a produced water outlet which are arranged at the top of the membrane shell. And part of the membrane modules are changed into a mode of water inlet at the upper end of the membrane shell, water outlet from the lower end of the membrane shell and concentrated solution. The structure leads the flow from water inlet to water outlet to be long, and the flow can reach dozens of meters, so the membrane is easy to be polluted, and the concentration polarization phenomenon is obvious. On the other hand, the structure of the central pull rod can not ensure the internal pre-tightening of the membrane shell, and simultaneously has a series of defects of complex installation, increased weight and the like which influence the stability and the economical efficiency.
Disclosure of Invention
The invention aims to provide a novel disc tube type reverse osmosis membrane component structure to overcome the defects. The technical scheme of the invention is as follows:
the utility model provides a novel dish tubular reverse osmosis subassembly, upper and lower flange at membrane shell, the inside membrane core of membrane shell and membrane shell both ends, the membrane core includes the flow guide disc of a plurality of stack combinations, and flow guide disc quotation one side is provided with a plurality of bumps and seal ring groove, and quotation opposite side welding reverse osmosis diaphragm, and it is sealed to the diaphragm to be equipped with O type circle in the seal ring groove, and two adjacent flow guide discs pass through the location boss on the flow guide disc hole and connect with the block mode to make the hole of superimposed flow guide disc form and produce the water passageway, the flow guide disc quotation periphery is the outer ring platform, and two breachs are seted up to the outer ring platform, the through-hole is seted up to membrane shell both sides with two breachs correspond and form water.
Furthermore, the novel disc tube type reverse osmosis component has a structure in a clamping mode that the positioning bosses comprise an upper positioning table above the surface of the flow guide disc and a lower positioning table below the surface of the flow guide disc, the upper positioning table and the lower positioning table are respectively provided with a tenon and a mortise, and the positioning bosses of two adjacent flow guide discs are mutually clamped and fixedly sealed through the tenon and the mortise.
Furthermore, the upper flange and the lower flange of the novel disc tube type reverse osmosis component are hermetically assembled with the upper end and the lower end of the membrane core.
Furthermore, the novel disc tube type reverse osmosis assembly is characterized in that the upper part of the membrane shell is open and is provided with external threads, the membrane core, the upper flange and the lower flange are arranged in the membrane shell, and the membrane core, the upper flange and the lower flange are pre-tightened and fixed in the membrane shell by screwing the nuts.
Furthermore, the upper flange and the nut of the novel disc tube type reverse osmosis component are provided with through holes which are communicated with the water production channel to form a water outlet.
The principle and the beneficial effects of the invention are as follows:
1. the invention has the creativity that the water inlet and outlet form of the traditional disc tube type flat membrane component is changed. The inlet water of the treatment liquid enters from one side of the membrane shell, the gap between the membrane shell and the outer annular platform of the diversion disc is the reserved inlet water space, the inlet water directly passes through the surface of the diversion disc, the turning-back process is not needed, and the inlet water is directly discharged from a concentrated liquid outlet formed by the gap between the other side of the membrane shell and the outer annular platform of the other side of the diversion disc; the water production channel is not additionally arranged, but the position of the original central pull rod is formed into the water production channel, the forming mode of the water production channel is that the diversion disks and the diaphragms are welded into a whole, the adjacent diversion disks are combined and connected through the clamping design of the positioning lug bosses of the diversion disks, the central hole of the superposed diversion disks and the sealing ring arranged on the circumference of the superposed diversion disks enable the central part to form the water production channel, the produced water through the reverse osmosis membrane discharges the membrane shell along the channel, the water is produced by utilizing the position of the original central pull rod, the water production channel does not need to be additionally arranged, and the running mode that the treatment liquid enters the module in the past is changed. In the process, the flow path that the liquid to be treated can be turned back and forth along the diversion disc from top to bottom or from bottom to top in the membrane shell for up to ten meters is reduced, and the distance from the water inlet to the penetrating fluid outlet is only one diversion disc surface, so that the pollution of the process to the membrane is greatly reduced, and the concentration polarization phenomenon can be greatly reduced;
2. the other creativity is that the traditional central pull rod is cancelled, the function of the central pull rod for installing the flow guide disc and the diaphragm is replaced by the clamping design of the flow guide disc, the function of the central pull rod as a pressure bearing is replaced by directly pre-tightening the membrane cores between the upper flange and the lower flange and between the upper flange and the lower flange through the nuts and installing the membrane cores inside the membrane shell, the working stability of the membrane assembly and the economic and environmental protection performance in manufacturing, installing and using are greatly improved, and the integration of the whole product is obviously improved compared with that of the traditional product.
