Description
Technical field
It the utility model is related to silicon carbide micro-powder production equipment technology, and in particular at a kind of carborundum industrial water
Manage equipment back purge system.
Background technology
Carborundum（SiC）Also known as diamond dust is with quartz sand, petroleum coke（Or coal tar）, wood chip（When producing green silicon carbide
Need to add salt）Formed Deng raw material by resistance furnace pyrolytic semlting.There is also rare mineral, Mo Sang in the Nature for carborundum
Stone.Carborundum is also known as moissanite.In the non-oxidized substance high-tech refractory raw material such as contemporary C, N, B, carborundum is most widely used
General, most economical one kind, it is properly termed as corundum or fire sand.The carborundum of Chinese industrial production at present is divided into black silicon carbide
Two kinds of silicon and green silicon carbide, it is hexagonal, proportion is 3.20~3.25, and microhardness is 2840~3320kg/mm2.
At present, green silicon carbide is set, it is necessary to prepare substantial amounts of pure water during grading technology in counter-infiltration pure water
In standby, most make us headache be exactly stifled film because the fenestra of reverse osmosis membrane can have a strong impact on aquifer yield after being blocked, for solution
This problem, regularly film must be rinsed, nevertheless, after using a period of time, fenestra can still block, because conventional
Backwashing manner is is rinsed in reverse osmosis membrane Membrane cover raw water area side, and reverse osmosis membrane is due to many miscellaneous in the presence of high pressure
Matter is all trapped in fenestra, and above-mentioned backwashing manner can not solve the problems, such as stifled film.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of carborundum industrial water processing equipment backwash dress
Put, the utility model efficiently solves the backwashing manner that existing counter-infiltration pure water equipment uses during actually water processed can not
Solves the problems, such as stifled film.
The utility model is achieved through the following technical solutions：
A kind of carborundum industrial water processing equipment back purge system, it is characterised in that：The back purge system includes
High-pressure hydraulic pump（11）, counter-infiltration Membrane cover（2）, elevated tank（7）, concentrated water flow control valve（4）, recoil drain solenoid valve（5）, instead
Permeate Membrane cover（2）Including reverse osmosis membrane（3）, reverse osmosis membrane（3）Downside is raw water side（10）, upside is water purification side（9）, water under high pressure
Pump（11）Pass through raw water water inlet pipe（12）Raw water is pumped into reverse osmosis membrane set（2）Raw water side（10）, counter-infiltration Membrane cover（2）It is net
Water side（9）Pass through pure water water-supply-pipe（8）With elevated tank（7）Connection, counter-infiltration Membrane cover（2）Raw water side（10）Pass through concentrated water
Drainpipe（6）It is provided with concentrated water flow control valve（4）, recoil drain solenoid valve（5）.
The further Technological improvement plan of the utility model is：
The concentrated water flow control valve（4）With the drain solenoid valve that recoils（5）It is arranged in parallel in concentrated water drainpipe（6）On.
The further Technological improvement plan of the utility model is：
The concentrated water flow control valve（4）For hand control valve, for adjusting counter-infiltration Membrane cover（2）The stream of outer row's concentrated water
Amount.
The utility model compared with prior art, has following obvious advantage：The utility model uses back purge system, leads to
The pressure differential of counter-infiltration Membrane cover water purification side and raw water side is crossed, is zero by adjusting recoil drain solenoid valve to adjust raw water lateral pressure,
So as to be pasted onto on film and intrapore impurity rinses, and the considerably less can of pure water used solves to block up film
Problem.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, back purge system of the present utility model include high-pressure hydraulic pump 11, counter-infiltration Membrane cover 2, elevated tank 7,
Concentrated water flow control valve 4, recoil drain solenoid valve 5, counter-infiltration Membrane cover 2 include reverse osmosis membrane 3, and the downside of reverse osmosis membrane 3 is raw water
Side 10, upside are water purification side 9, and raw water is pumped into the raw water side 10 of reverse osmosis membrane set 2 by raw water water inlet pipe 12 by high-pressure hydraulic pump 11,
The water purification side 9 of counter-infiltration Membrane cover 2 is connected by pure water water-supply-pipe 8 with elevated tank 7, and the raw water side 10 of counter-infiltration Membrane cover 2 is logical
Cross concentrated water drainpipe 6 and be provided with concentrated water flow control valve 4, recoil drain solenoid valve 5, the concentrated water flow control valve 4 and recoil
Drain solenoid valve 5 is arranged in parallel on concentrated water drainpipe 6, and the concentrated water flow control valve 4 is hand control valve, anti-for adjusting
Permeate outside Membrane cover 2 and arrange the flow of concentrated water.
Illustrate the course of work of the present utility model below in conjunction with the accompanying drawings.
Raw water is pressed into the raw water side 10 of counter-infiltration Membrane cover 2 by high-pressure hydraulic pump 11 by the raw water that raw water water inlet pipe 12 conveys,
Because recoil drain solenoid valve 5 is closed, the uninterrupted of concentrated water is arranged outside regulation concentrated water flow control valve 4；Due to original
The raw water of water side 10 is in high pressure conditions, and most of water enters water purification side 9 through reverse osmosis membrane 3 under the effect of the pressure, former
Solute and impurity in water are trapped within raw water side 10.The pure water of water purification side 9 is transported to pure water height through pure water water-supply-pipe 8
Position water tank 7, is then transported to water equipment through pure water outlet 1.The solid impurity of raw water side 10 is trapped within, in water under high pressure
Under effect, it is set to be pasted onto on reverse osmosis membrane 3, so as to block the water penetration of the fenestra of reverse osmosis membrane 3.When high-pressure hydraulic pump 11 stops work
After work, recoil drain solenoid valve 5 open, the pressure of raw water side 10 is reduced to 0, water purification side 9 due to being connected with elevated tank 7, therefore
And still have enough pressure, force pure water to return to raw water side 10 by fenestra, will can thus be pasted onto on reverse osmosis membrane 3
Impurity rinses, so as to reach the purpose for washing film.Using the method for this backwash, pure water used is few.
Technological means disclosed in the utility model is not limited only to the technological means disclosed in above-mentioned embodiment, also
Including being combined formed technical scheme by above technical characteristic.It should be pointed out that the ordinary skill for the art
For personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these are improved and profit
Decorations are also considered as the scope of protection of the utility model.
