Description
Technical field
The utility model belongs to the water purification apparatus, particularly makes the equipment of water purifying treatment of mode of reverse osmosis.
Background technology
What current experiments chamber ultrapure water machine adopted usually is surge pump, and at present commercially available surge pump flow when satisfying the operating pressure of reverse osmosis membrane is all less, and when being used to make the two steps ro ultrapure water machine, the general maximum of the system water yield per hour only has several decaliters; When requiring to make the water yield per hour more than 100 liters the time, the ability of surge pump just is difficult to reach requirement.Reverse osmosis unit in the industrial production adopts the higher high-pressure pump of lift usually, as the operating pressure and the flow of reverse osmosis membrane are provided with vertical multi-stage centrifugal pump; For the two steps ro device, first-stage reverse osmosis film and two-pass reverse osmosis film need to use respectively high-pressure pump separately in the prior art, are called one-level high-pressure pump and secondary high-pressure pump.But the high-pressure pump that full scale plant is used is compared with surge pump as vertical multi-stage centrifugal pump, and power is big, and volume is big, and its volume is more than ten times of surge pump often.Therefore, when being used to make the bigger two steps ro ultrapure water machine of the water yield, make high-pressure pump if adopt prior art that two vertical multi-stage centrifugal pumps are set, the volume of device will increase a lot, current consumption also will increase greatly, and the high-pressure pump noise of full scale plant is bigger than surge pump, if adopt two high-pressure pump, noise will double again.
Summary of the invention
At the above-mentioned defective that prior art exists, intend the reverse osmosis unit in the existing industrial production is improved, design a kind of compact construction, volume is less, the big flow type two steps ro formula ultrapure water machine that power consumption economizes.
The technical solution adopted in the utility model is as follows.
A kind of big flow type two steps ro formula ultrapure water machine, include pre-treatment and filter assembly, high-pressure pump, first-stage reverse osmosis assembly and two-pass reverse osmosis assembly, first-stage reverse osmosis assembly one end has one-level pure water rising pipe and one-level wastewater effluent pipe, two-pass reverse osmosis assembly one end has secondary pure water rising pipe and secondary wastewater effluent pipe, the first-stage reverse osmosis assembly the other end and the two-pass reverse osmosis assembly the other end are respectively equipped with water-in, it is characterized in that: high-pressure pump is arranged on before the first-stage reverse osmosis assembly water-in; One-level pure water rising pipe is communicated with two-pass reverse osmosis assembly water-in; Be provided with recycle pump between secondary wastewater effluent pipe and the one-level pure water rising pipe, pump inlet is communicated with secondary wastewater effluent pipe, and circulating-pump outlet is communicated with one-level pure water rising pipe.
The utility model is work like this, tap water is pressurizeed by high-pressure pump after pre-treatment is filtered, handle through the first-stage reverse osmosis assembly, the one-level pure water that obtains enters the two-pass reverse osmosis assembly having under the pressure state, handle through the two-pass reverse osmosis assembly, the secondary pure water of gained is flowed out by secondary pure water rising pipe, uses for the user; The secondary waste water part of gained is fallen by secondary wastewater effluent tube drainage, or is recycled to and reenters high-pressure pump before the high-pressure pump and utilize once more, and another part returns through the recycle pump foldback to be incorporated the two-pass reverse osmosis assembly into the one-level pure water in the one-level pure water rising pipe and handle.Adopt this design, high-pressure pump can provide the system water conservancy project of first-stage reverse osmosis assembly and two-pass reverse osmosis assembly to make pressure simultaneously, the pump around circuit of secondary waste water has increased the flow velocity of reverse-osmosis membrane element in the two-pass reverse osmosis assembly of flowing through, make that the rate of recovery of two-pass reverse osmosis membrane element can be not too high, and make the rate of recovery of two-pass reverse osmosis membrane element can reach that the rate of recovery is lower than 30% regulation in the reverse-osmosis membrane element guide rule.
The big flow type of the utility model two steps ro formula ultrapure water machine compact construction, volume is less, the power consumptive province, an available high-pressure pump provides the system water conservancy project of first-stage reverse osmosis assembly and two-pass reverse osmosis assembly to make pressure simultaneously, the rate of recovery that just can guarantee reverse-osmosis membrane element in the two-pass reverse osmosis assembly with a little recycle pump is lower than 30%, make its regulation that meets the reverse-osmosis membrane element guide rule, prolonged the work-ing life of reverse-osmosis membrane element.It had both overcome the not enough shortcoming of the surge pump system water yield, had avoided adopting two industrial high-pressure pump volumes big again, and power consumption is many, the shortcoming that noise is big.
