Abstract
The utility model discloses an anti-permeation constant flow control system, comprising a pressure control system and an anti-permeation device; wherein the pressure control system comprises a pressure feedback device and a high pressure pump, the anti-permeation device comprises a water inlet pipe, a water production pipe and a concentrated water pipe, the water inlet pipe is connected with the high pressure pump and the pressure feedback device in turn, the high pressure pump is provided with a variable frequency controller, and the water production pipe is provided with a water production flow meter. When anti-permeation water production flow is higher or lower than a preset value, the water production flow meter feeds signal to the high pressure pump which changes the frequency of a power supply via the variable frequency controller, to control the speed of a motor and adjust water intake flow, thereby realizing constant flow of water production. The anti-permeation constant flow control system can confirm the quality of output water and resolve the problem as instable flow of anti-permeation water output, and has low equipment investment and operation cost.
Description
Technical field
The utility model relates to counter-infiltration constant flux control system.
Background technology
Counter-infiltration is a new membrane separation technique that grows up the sixties in last century, and reverse osmosis membrane relies on the solvent that makes under the pressure-driven in the solution to be separated with solute.Under certain pressure, H2O molecule in the former water can pass through the RO film, and impurity such as the inorganic salts in the former water, heavy metal ion, organism, colloid, bacterium, virus can't pass through the RO film, thereby pure water that can see through and the condensed water strictness that can't see through are made a distinction.Reverse osmosis equipment is present a kind of common process water production equipment, is widely used in fields such as scientific research, medicine, food, beverage, desalinization.Reverse osmosis unit is in operational process, because of labile factors such as the water temperature of outer net water inlet, intake pressure, raw water quality cause the instability of producing discharge, if contained salinity or organism are higher in the former water, then osmotic pressure also increases, under the constant situation of intake pressure, net pressure will reduce, and water production rate reduces; Moreover along with the increase of water temperature, the increase that water flux is also linear, just increase/minimizing 2.5%～3.0% of water flux is produced in 1 ℃ of the every rising of water inlet water temperature/reductions, and the variation of the water temperature of intaking can influence water production rate equally.So it is very necessary that discharge is produced in control, because too high product discharge, the too high recovery have not only strengthened concentration polarization, can cause the salt rate to rise again, thereby cause the salt rejection rate influence that descends to produce water water quality.If the water production rate deficiency then can't guarantee the stability that supplies water.
The utility model content
Technical problem to be solved in the utility model provides a kind of in assurance water flow, equipment investment cost and the cheap counter-infiltration constant flux control system of operating cost.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: counter-infiltration constant flux control system, comprise control pressurer system and reverse osmosis unit, described control pressurer system comprises pressure feedback device, high-pressure pump, described reverse osmosis unit is provided with inlet channel, water producing pipe road and dense waterpipe, described inlet channel connects high-pressure pump, pressure feedback device successively, and described high-pressure pump is provided with frequency-variable controller, and described water producing pipe road is provided with the product water ga(u)ge.
Described pressure feedback device is a pressure unit.
Described inlet channel is provided with tensimeter.
