Abstract
The utility model discloses a water-gas mix cleaning device for an ultrafiltration membrane. The water-gas mix cleaning device comprises an ultrafiltration membrane component; a water inlet adjusting valve, a water-yielding adjusting valve and a water-concentrating adjusting valve are respectively arranged at a water inlet, a water-yielding opening and a water-concentrating opening of the ultrafiltration membrane component; an injector is arranged at a water inlet bypass of the ultrafiltration membrane component; and the injector comprises a venturi nozzle, a suction chamber, and a diffusing pipe which are sequentially connected. In the utility model, the technical scheme that gas is led into the ultrafiltration membrane component automatically under the action of a jet nozzle, so that the inconvenience of arranging a gas source additionally is avoided. Compressed gas blasts in the inner fiber of the ultrafiltration membrane component to cause vibration, so that pollutant adhered to the surface of membrane fiber is removed and taken away by wash water, and the purposes of strengthening the washing effect and reducing the backwash water consumption are achieved.
Description
Technical field
The utility model relates to milipore filter gas-vapor mix cleaning device.
Background technology
Ultrafiltration is to utilize the pressure active membrane, the relative higher material of colloid, particle and molecular weight in the trap water under the effect of extraneous motive force (pressure), and water and little particles of solute see through the separation process of film.When processed water by means of the work of ambient pressure in order to certain flow velocity during by the film surface, hydrone and small-molecular weight solute see through film, and greater than the particulate of fenestra, big molecule etc. since sieving actoion be trapped, thereby water is purified.In ultra-filtration process, big molecule solute such as the particulate in the treat liquid, colloidal particle, organic matter and microorganism and film produce physics chemical action and mechanism and cause absorption in film surface or fenestra, precipitation diminish fenestra or stop up, and cause the permeable amount or the separating power decline of film.Because the impurity that is trapped is constantly accumulation on the film surface, can produce the concentration polarization phenomenon, because the generation of concentration polarization, especially under low flow velocity, high solute concentration situation, when the milipore filter surface meets or exceeds the saturated concentration of solute, the formation of gel layer is just arranged, cause the saturating liquid flux of film not rely on ultrafiltration pressure.The saturating liquid flux of film after the pollution descends, and the ultrafiltration effect worsens, the lost of life, and the cleaning difficulty is big, has had a strong impact on the operating efficiency and the economic benefit of ultrafiltration.For guaranteeing the long-term stability operation of ultrafiltration system, not only need dispose backwash system, chemical cleaning system, purging system, and the gas-vapor mix purging system is also essential.Usually the gas that will purify is sent into ultrafiltration module with water, and under the effect of gas, mixed liquor is known from experience at the violent stirring action of film surface generation, has good clean effect.
Gas-vapor mix purging system configuration air compressor commonly used is brought air into from bypass and is entered milipore filter, produces the effect of water and the common scouring of air on the milipore filter surface, and the polluter attached to the membrane fiber surface is peeled off, and is rinsed water and takes away.This equipment need be established source of the gas in addition, makes complex structure.
The utility model content
Technical problem to be solved in the utility model provides does not need to establish in addition source of the gas, milipore filter gas-vapor mix cleaning device simple in structure, with low cost.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: milipore filter gas-vapor mix cleaning device, comprise hyperfiltration membrane assembly, the water inlet of described hyperfiltration membrane assembly, the product mouth of a river, concentrated water spout are respectively equipped with into water control valve, product water regulating valve, dense water regulating valve, the water inlet bypass of described hyperfiltration membrane assembly is provided with injector, and described injector comprises venturi nozzle, suction chamber, the diffuser pipe that connects successively.
The import and export of described injector are respectively equipped with control valve behind control valve before the injector, the injector.
Described hyperfiltration membrane assembly is provided with the PLC control circuit, and this PLC control circuit connects control valve behind control valve before the described water inlet control valve, injector, the injector.
The utility model utilizes the effect of jet blower owing to adopted technique scheme, brings air into hyperfiltration membrane assembly automatically, has saved the inconvenience of establishing source of the gas in addition.The concussion that utilizes Compressed Gas explosion between the fiber in hyperfiltration membrane assembly to form is peeled off the polluter attached to the membrane fiber surface, and is rinsed water and takes away, thereby reaches the purpose of strengthening developing result and saving the backwash water consumption.This device does not need to establish in addition source of the gas, simple in structure, with low cost.
Description of drawings

Fig. 2 is the structural representation of injector among this embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
Figure 1 shows that the utility model milipore filter gas-vapor mix cleaning device, comprise hyperfiltration membrane assembly 1, the water inlet of described hyperfiltration membrane assembly 1, the product mouth of a river, concentrated water spout are respectively equipped with into water control valve 11, product water regulating valve 12, dense water regulating valve 13, the water inlet bypass of described hyperfiltration membrane assembly 1 is provided with injector 2, as shown in Figure 2, described injector 2 comprises venturi nozzle 21, diffuser pipe 22 and is located at suction chamber 23 between venturi nozzle 21, the diffuser pipe 22.The import and export of described injector 2 are respectively equipped with control valve 32 behind control valve 31 before the injector, the injector.Described hyperfiltration membrane assembly 1 is provided with the PLC control circuit, and this PLC control circuit connects control valve 32 behind control valve 31 before the described water inlet control valve 11, injector, the injector.
During normal operation, open into water control valve 11, close control valve 32 behind control valve 31 before the injector, the injector; Be provided with by the PLC time parameter and close into water control valve 11 when regularly cleaning, before the injector behind control valve 31, the injector control valve 32 open automatically.
The ultrafiltration influent side has certain working pressure, working fluid enters suction chamber 23 by venturi nozzle 21, forming vacuum through the exit region at venturi nozzle 21 in the diffuser pipe 22, thereby air is brought into, and gas-vapor mix enters hyperfiltration membrane assembly 1, forms the effect of water and air bump rinse operation on the milipore filter surface, make the film silk produce shake, by the shear action of water, scrub off the pollutant on milipore filter surface, thereby reach the purpose of strengthening developing result and saving water consumption.
