Description
Technical field
The utility model relates to middle water reclamation technology field, relates in particular to a kind of energy-conservation immersion ultrafiltration apparatus.
Background technology
The middle water of industries such as the immersion ultrafiltration apparatus is widely used in printing and dyeing, plating, papermaking reclaims, consider according to maximum stream flow during its design, as shown in Figure 1, connect successively between membrane cisterna 7 and the product pond 8 and produce water valve 5, self priming pump 9, outlet valve 4, flowmeter 2, outlet valve 1,10 of the outlet pipes that links to each other with outlet valve 1 reach and produce 8 upper ends, pond.Traditional operating process is: when membrane cisterna 7 high liquid levels, producing water valve 5, outlet valve 4 and outlet valve 1 opens, self priming pump 9 brings into operation, and produces water and enters ultrafiltration product pond 8, when membrane cisterna 7 hangs down liquid level, water inlet pneumatic operated valve 6 is opened, membrane cisterna 7 replenishes former water from raw water box, and when raw water box did not have liquid level yet, self priming pump 9 stopped, produce water valve 5 and close, stop to produce water.This kind mode can cause the frequent unlatching of self priming pump 9 when former water is not enough, be unfavorable for the stable of system.There is tangible dull and rush season in some enterprise, is 1500t/d such as design discharge, has only 500t/d in the dull season, if must cause frequent startup-shutdown according to normal mode of operation in the past, cause the film silk regular accept pulse, quicken the damage of film silk; And system can autostop when the raw water box liquid level is low, and at this moment having membrane cisterna 7 just needs backwash, and cause can not backwash and shut down, and makes film silk surface aggregation dirt, along with the prolongation of time, might stop up fenestra; Attempting to turn down pump discharge in addition, to control the measure of flow also be worthless, because what the immersion ultrafiltration was used is self priming pump, self priming pump generally is displacement pump or the tendency that displacement pump is arranged, and closes minor valve and causes pump discharge pressure sharply to raise, and the long-time running meeting causes the damage of pump and pump discharge pipeline.
Summary of the invention
The defective of frequent switching on and shutting down when having low discharge at existing immersion ultrafiltration apparatus; the utility model provides a kind of stable operation for a long time; when low discharge not frequently switching on and shutting down make the regular pulse of pair of films silk; but shut down when avoiding membrane cisterna just to need backwash because of liquid level is low; need not drive self priming pump, not only save the energy-conservation immersion ultrafiltration apparatus that energy has also been avoided the wearing and tearing of pump.
For achieving the above object, the utility model adopts following technical scheme:
Energy-conservation immersion ultrafiltration apparatus, comprise membrane cisterna, produce the pond, connect successively between described membrane cisterna and the product pond and produce water valve, self priming pump, outlet valve, flowmeter, outlet valve, between product water valve and outlet valve by-passing valve is set, the outlet pipe that links to each other with outlet valve stretches into the bottom of producing the pond.Opening of by-passing valve can make water without pump, can reduce most of resistance like this, and outlet pipe stretches into the bottom of producing the pond makes the water producing pipe road all seal to producing the pond from membrane cisterna, avoids gas leakage.A rotary knob is arranged on the control panel of self priming pump, and it has three positions, 1. stops 2. manually 3. automatic control.Under the situation that power supply is being opened: button is when " stopping ", and pump is at a stop; Button is when " manually ", and pump is operation manually; Button is when " automatically ", and pump can move according to programme-control.The power supply of self priming pump is arranged on the position of " pass ", and rotary knob is on " automatic control " position, and the self priming pump control of not choosing can allow its automatic operation.During the high liquid level of membrane cisterna, by-passing valve cuts out, and produces water valve, outlet valve, outlet valve and opens the self priming pump operation, behind the stability of flow, self priming pump cuts out, and opens by-passing valve, owing to produce the pond underground, be lower than the membrane cisterna water level, utilize siphon principle water to flow out, enter and produce the pond from outlet valve.Because self priming pump does not move, can save the considerable electricity charge during dull season, avoided the frequent switching on and shutting down of system simultaneously, reduce infringement to the film silk.
As preferably, described flow is counted vortex-shedding meter.Vortex-shedding meter is compared with spinner flowmeter, can reduce pipe resistance, is beneficial to the siphon water outlet.
Energy-conservation immersion ultrafiltration apparatus of the present utility model has increased the siphon bypass on the basis of self priming pump; when low discharge, need not the frequent starting self priming pump; utilize siphon principle to produce water; make the immersion ultrafiltration apparatus in enterprise's stable operation for a long time during dull season; reduce the impact number of times of frequent start to film silk instantaneous pressure; but shut down when avoiding membrane cisterna just to need backwash, need not drive self priming pump, not only saved the wearing and tearing that energy has also been avoided pump because of liquid level is low.
Description of drawings
Fig. 1 is the structural representation of existing immersion ultrafiltration apparatus.
Fig. 2 is the structural representation of the energy-conservation immersion ultrafiltration apparatus of the utility model embodiment.
The specific embodiment
Below in conjunction with the Fig. 2 and the specific embodiment the utility model is described further.
Energy-conservation immersion ultrafiltration apparatus, as shown in Figure 2, comprise membrane cisterna 7, produce pond 8, connect successively between described membrane cisterna 7 and the product pond 8 and produce water valve 5, self priming pump 9, outlet valve 4, flowmeter 2, outlet valve 1, between product water valve 5 and outlet valve 1 by-passing valve 3 is set, the outlet pipe 10 that links to each other with outlet valve 1 stretches into the bottom of producing pond 8.Described flowmeter 2 is a vortex-shedding meter.
During the high liquid level of membrane cisterna 7, by-passing valve 3 cuts out, and produces water valve 5, outlet valve 4, outlet valve 1 and opens, self priming pump 9 operations, behind the stability of flow, self priming pump 9 cuts out, power supply with self priming pump 9 is arranged on the position of " pass " afterwards, and the rotary knob on self priming pump 9 control panels is on " automatic control " position.Open by-passing valve 3,, be lower than membrane cisterna 7 water levels, utilize siphon principle water to flow out, enter and produce pond 8 from outlet valve 1 owing to produce pond 8 underground.
Certain printing and dyeing mill's immersion ultrafiltration apparatus design discharge is 130t/h, and have only 40t/h dull season, if according to former operational mode, the metered flow of a self priming pump 9 is 90/h, actual aquifer yield is 80t/h, and the every unlatching of ultrafiltration apparatus will stop 40 minutes half an hour like this.Use the utility model, utilize the siphon principle aquifer yield can reach 35t/h, ultrafiltration this moment just can long-play, operation after 18 hours because raw water box is full, open self priming pump 9 this moment, the immersion ultrafiltration apparatus moves according to original mode, and the low liquid level of raw water box switches to siphon bypass operation after 3 hours.The power of self priming pump 9 is 32KW, and self priming pump 9 shutdown every day were probably saved the 576KW electric energy in such one day by 18 hours, and every kilowatt of monobasic of commercial power average price can be saved 576 yuan of electricity charge in such one day, and one month is 17280 yuan.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model, and all equivalences of doing according to the content of the application's claim change and modify, and all should be technology category of the present utility model.
