Abstract

The utility model discloses an ultrapure water machine with a double wavelength ultraviolet which includes a fine filter, a reverse osmosis (RO) system, an ultra pure (UP) system, the double wavelength ultraviolet (185 nm, 185 nm) and a ultra-filtration (UF) system. All system units are connected to transmit through a polyethylene (PE) pipe/ 2. The ultrapure water machine with a double wavelength ultraviolet is characterized in that the double wavelength ultraviolet is installed between the UP system and the UF system. The double wave ultraviolet is composed by a lampshade, a cable, a seal, a water inlet, a water outlet, 185 nm tube and 254 nm light tube, wherein the 185 nm tube is connected with the 254 nm tube. The ultrapure water enters into the ultraviolet through the water inlet of the double wavelength ultraviolet, and the total organic carbon (TOC) is reduced by the 185 nm light tube at first, and sterilized by the 254 nm light tube. The ultrapure water machine with a double wavelength ultraviolet has the advantages of being simple in structure, without manual operation, and the use standards of the pure water through double wavelength ultraviolet are greatly improved.

Description

A kind of ultrapure water machine with dual wavelength ultraviolet

Technical field

The utility model relates to the equipment for preparing pure water, particularly use for laboratory, adopts reverse osmosis technology and ion exchange technique to produce the ultrapure water machine of ultrapure water.

Background technology

At present, in laboratory and industrial ultrapure water machine, most of ultrapure water machine is all with single ripple (185nm or 254nm) ultraviolet sterilization instrument, but up to the present, also there is not a ultrapure water machine to dispose dual wavelength ultraviolet (185nm, 254nm), the 185nm ultraviolet mainly reduces TOC (total organic carbon) content in the ultrapure water, 254nm mainly is to the ultrapure water sterilization that carries out disinfection, this is novel to have played the effect of working along both lines, TOC and bacterium have been played the removal effect, and this novel be to adopt built-in two tubes of lampshade, thoroughly change a traditional lampshade and only pacified a tubes, also can only play an effect, will change this present situation and basis is novel.

The utility model content

The purpose of this utility model namely produces thus, a kind of ultrapure water machine with dual wavelength ultraviolet is proposed, make machine that a ultraviolet is installed and play two kinds of effects, the one, the removal of bacteria rate of ultrapure water is reached 99%, the 2nd, the TOC (total organic carbon) of ultrapure water is down to below the 3PPb, and the ultraviolet of traditional ultrapure water machine is to use single length ultraviolet basically, the 254nm fluorescent tube is with the most use, next is the 185nm fluorescent tube, so its effect also can only be a kind of, sterilization or fall TOC, and this novel be to unite two into one, play two-tube effect under it.

For achieving the above object, the utility model is achieved through the following technical solutions: a kind of ultrapure water machine with dual wavelength ultraviolet, comprise the essence filter, the RO system, the UP system, dual wavelength ultraviolet (185nm, 254nm) with the UF system, all system elements all are to be connected by 2 minutes PE water pipes to transmit, described dual wavelength ultraviolet is installed between UP system and the UF system, UP system water out is ultrapure water, its specific conductivity is extremely low, pass through again the dual wavelength ultraviolet sterilization and fall TOC, and bacterium can stay the bacterium corpse after killing, namely intracellular toxin, tackle so need increase a UF system in the dual wavelength ultraviolet rear end, guarantee to produce the water quality of water.

Further, described dual wavelength ultraviolet, by lampshade, cable, seal, water-in, water outlet, 185nm fluorescent tube and 254nm fluorescent tube form, and 185nm fluorescent tube and 254nm fluorescent tube are connected in one, ultrapure water enters ultraviolet by the water-in of dual wavelength ultraviolet, first by the 185nm fluorescent tube TOC falls, under the action of ultraviolet radiation of 185nm wavelength, free hydroxyl in the water is intensified, and constantly impact chemical bond between the organism, destroying the chemical bond that connects between the organism under the ultraviolet catalysis, the chemical reaction of process series of complex finally makes organic carbon be decomposed into the most basic carbonic acid gas and water.Carry out sterilization by the 254nm fluorescent tube again, wavelength is DNA (thymus nucleic acid) and the RNA (Yeast Nucleic Acid) that the ultraviolet wastewater of 254nm directly destroys cell, virus, makes microorganism dead rapidly.

Further, described 185nm and 254nm refer to the wavelength of ultraviolet.

The beneficial effects of the utility model are: by being installed on the dual wavelength ultraviolet between UP system and the UF system, make machine reach 99% to the removal of bacteria rate of ultrapure water, but also the TOC (total organic carbon) of ultrapure water is down to below the 3PPb, this device structure is simple, need not manual operation, greatly improved the Application standard of pure water.
