Description

Three the tunnel three show multi-functional ultrapure water machine

Technical field

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

Background technology

At present, the laboratory is with in the ultrapure water machine, and most of machine has possessed the monitoring function of pure water part water quality.But up to now, also there is not a kind of machine to realize on the market to the former water of machine, RO water (water after the reverse-osmosis treated), three kinds of functions that water quality is monitored simultaneously of UP water (water after ultrapure water, mixed ion exchanger are handled).

The utility model content

The purpose of this utility model provides a kind of three the tunnel three and shows multi-functional ultrapure water machines, and the former water of machine, RO water, UP water are monitored simultaneously, with effective protection RO film (reverse osmosis membrane), increase the service life, guarantees effluent characteristics simultaneously.

This novel purpose is achieved in that a kind of three the tunnel three show multi-functional ultrapure water machine, comprises that the polypropylene filter, reverse osmosis membrane processing device, mixed ion exchanger and the polishing that are connected in turn by pipeline mix bed; Display unit is connected with central processing unit; Be respectively arranged with into the water electricity on reverse osmosis membrane processing device suction culvert and the outlet pipeline and lead detection probe and go out water power and lead detection probe, the outlet pipeline of mixed ion exchanger is provided with water outlet resistance detection probe; Water inlet electricity is led detection probe and is gone out water power and leads the output signal of detection probe and water outlet resistance detection probe be delivered to described central processing unit after the A/D converting unit is handled.

Compared with prior art, this novel beneficial effect is:

1, a plurality of links of ultrapure water is monitored, guaranteed that finally effluent characteristics reaches processing requirement.

In the forward and backward pipeline of reverse osmosis membrane processing device, set up into water and go out water power and lead detection probe, it is gone into quality and effluent characteristics is monitored simultaneously, can control easily on the one hand into quality, guarantee that the RO film works under the operating mode allowing all the time, do not have excessive and unallowed impurity and bring the RO film into and it is caused damage; On the other hand, RO film effluent characteristics is accomplished to know what's what, if the RO effluent characteristics does not reach requirement, then there is the possibility of cleaning, safeguarding or changing in the RO film.In addition, and the water quality after mixed ion exchanger handled carries out the water outlet electrical resistance monitoring, guarantees that final outflow water water quality meets processing requirement.

2, the RO film is formed effective protection, prolonged work-ing life.
