Description

Technical Field

[0001] The utility model relates to the technical field of pure water preparation, and specifically to a pure water production device. Background Art

[0002] RO water is reverse osmosis water, which is also commercially available pure water. Its principle is to apply a pressure greater than the osmotic pressure on one end of the raw water to produce a reverse osmosis effect. At this time, dissolved and non-dissolved inorganic salts, heavy metals, organic bacterial particles, etc. cannot pass through the semipermeable membrane, so that water molecules and smaller molecular salts penetrate the semipermeable membrane and flow to the side of the purified water, and the pollutants are concentrated in the raw water. The raw water is gradually concentrated, and the applied pressure must be gradually increased until it is infinite. In actual operation, the concentrated water (wastewater) is discharged and the raw water is continuously supplied to maintain a constant pressure.

[0003] The Chinese authorized patent with application number (CN202022812284.8) discloses an improved ultrapure water preparation instrument, including a base, a universal wheel and a filter box, the universal wheel is arranged at the bottom of the base, and the filter box is fixedly arranged on the top left side of the base; it is characterized in that it also includes a pillar, a water storage tank, a connecting pipe, a filter box, a first filter screen, an activated carbon adsorption plate, a first water pump, a first water pumping pipe, a first water supply pipe, a fine filter box, a compressed activated carbon ultrafiltration plate, a second water pump, a second water pumping pipe, a second water supply pipe, a filter press box, a partition, a permeation membrane, an air box, an air inlet pipe, an air bag and a water outlet pipe, the pillar is fixedly arranged on the top of the filter box, and the water storage tank is fixedly arranged on the top of the pillar;

[0004] The above scheme performs preliminary filtration on tap water through the filter in the filter box, and then further filters and adsorbs through the activated carbon adsorption plate and the compressed activated carbon ultrafiltration plate, and finally enters the filter press box to obtain the product through the osmotic membrane under a suitable pressure. However, there is a problem that the direct discharge of wastewater generated when the raw water passes through the osmotic membrane will lead to a large amount of wastewater waste, and the wastewater cannot be reused. For this reason, a pure water production device is proposed. Utility Model Content
