Description
Technical field
The utility model relates to water field of purification, particularly a kind of counter-infiltration purging system.
Background technology
In counter-infiltration system running, understand due to the concentrated deposition producing to indissoluble material in the existence of the polluters such as mud pool, jelly, organic matter, microorganism in former water and film separation process on reverse osmosis membrane surface, and then form the pollution to reverse osmosis membrane.We know, the pretreatment unit of counter-infiltration system is to cause that for removing as much as possible the material of film pollution is custom-designed, however, even if system has quite perfect pre-processing device can not avoid film pollution in use completely, so need to periodically remove the operation of pollutant in film system, this operating process is just called the cleaning on the spot of counter-infiltration system.
Utility model content
The problem existing for prior art, the purpose of this utility model is to provide a kind of counter-infiltration purging system that can periodically remove pollutant in film system.
In order to arrive above-mentioned purpose, the utility model is by the following technical solutions: a kind of counter-infiltration purging system, comprise cleaning water tank, flushing water pump and cleaning cartridge filter, described cleaning water tank is provided with water inlet, delivery port, circulating water intake and circulating water outlet, described delivery port is provided with the first valve, described circulating water outlet is connected with a side of the second valve, the opposite side of the second described valve is connected to the water inlet of flushing water pump, the water outlet of described flushing water pump is provided with the first pressure transmitter, the delivery port of described flushing water pump is connected with check-valves, between the first described pressure transmitter and check-valves, by the 3rd valve, be connected on the circulating water intake that cleans water tank, described check-valves is connected with the 4th valve, the 4th described valve is connected with in turn and cleans cartridge filter and the 5th valve, between the 4th described valve and cleaning cartridge filter, be provided with the second pressure transmitter, between described cleaning cartridge filter and the 5th valve, be provided with the 3rd pressure transmitter.The 5th described valve is connected with flowmeter.The first to the 5th described valve is Hand-operated butterfly valve.
Adopt after technique scheme, the utlity model has following beneficial effect: the utility model can periodically be removed pollutant in film system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, clean water tank 2, flushing water pump 3, clean cartridge filter 4, water inlet 5, delivery port 6, circulating water intake 7, circulating water outlet 8, the first valve 9, the second valve 10, the first pressure transmitter 11, check-valves 12, the 3rd valve 13, the 4th valve 14, the 5th valve 15, the second pressure transmitter 16, the 3rd pressure transmitter 17, flowmeter.
The specific embodiment
According to specification drawings and specific embodiments, the utility model is further explained below.
As described in Figure 1, a kind of counter-infiltration purging system, comprise and clean water tank 1, flushing water pump 2 and cleaning cartridge filter 3, described cleaning water tank 1 is provided with water inlet 4, delivery port 5, circulating water intake 6 and circulating water outlet 7, described delivery port 5 is provided with the first valve 8, described circulating water outlet 7 is connected with a side of the second valve 9, the opposite side of the second described valve 9 is connected to the water inlet of flushing water pump 2, the water outlet of described flushing water pump 2 is provided with the first pressure transmitter 10, the delivery port of described flushing water pump 2 is connected with check-valves 11, between the first described pressure transmitter 10 and check-valves 11, by the 3rd valve 12, be connected on the circulating water intake 6 that cleans water tank 1, described check-valves 11 is connected with the 4th valve 13, the 4th described valve 13 is connected with in turn and cleans cartridge filter 3 and the 5th valve 14, between the 4th described valve 13 and cleaning cartridge filter 3, be provided with the second pressure transmitter 15, between described cleaning cartridge filter 3 and the 5th valve 14, be provided with the 3rd pressure transmitter 16.The 5th described valve 14 is connected with flowmeter 17.The first to the 5th described valve is Hand-operated butterfly valve.
Clean cartridge filter 3 and be contained in counter-infiltration import department, to prevent that small solid particle from entering reverse osmosis membrane assembly, filter core adopts polypropylene material, should regularly replace to guarantee that flow of inlet water does not decline, otherwise may cause particle in water to enter reverse osmosis unit, shorten reverse osmosis membrane service life, therefore renew cartridge more when micro-filter pressure drop is increased to 0.08MPa.Native system manually moves, and the inlet and outlet pressure reading of current entry micro-filter is manually judged.
Working method: flushing water pump on control panel 2 is selected to enable possition, start flushing water pump 2, operating pressure is controlled below 0.4MPa, control valve is controlled flow, with low discharge, injects cleaning fluid, low pressure remover apparatus (pressure vessel) Yu Shui, with the pressure that only enough compensation concentrate the pressure drop of water outlet from intaking to, clean, this pressure should substantially not produce infiltration and is advisable, and low pressure can make concentrate deposit and reduce to minimum again on film, liquid circulation 30 minutes.Close flushing water pump 2, soaking and washing unit, generally, soak time is 1 hour; But for polluting more serious unit prolongation soak time, be useful, can soak 10～15 hours.Restart scavenging pump, the dirt peeling off with the flow flushing membrane surface clean with reference to subordinate list, if unit is seriously polluted, by the flow cleaning that exceeds subordinate list 150%, but high flow capacity can cause pressure drop, maximum allowed pressure drop is that each cleaning unit is 0.14MPa, circulates 30～60 minutes.
