Abstract
Disclosed is an ultrapure water purifier with the online monitoring function for total organic carbon (TOC), comprising a polypropylene filter, a reverse osmosis membrane processor, a mixed ion exchanger, a polishing mixed bed, a CPU and a display unit which are sequentially connected through a pipeline; a water outlet pipeline of a mixed ion processor is provided with a TOC detection probe; and the output signal of the detection probe is processed through an A/D conversion unit, then transmitted to the CPU. The ultrapure water purifier can online monitor the TOC of the ultrapure water and leads the user to timely have a general idea on the quantity of the TOC content in the water, thereby ensuring the water quality.
Description
Technical field
The utility model relates to pure water preparation equipment, particularly adopts reverse osmosis technology to produce the water purification machine of laboratory with ultrapure water.
Background technology
In the present laboratory ultrapure water machine, the TDS that some machine can reflect, and some machine connects can not reflecting of TDS, just more can not monitor TOC (total organic carbon) content in the water.
The utility model content
The purpose of this utility model provides a kind of total organic carbon on-line monitoring function ultrapure water machine, carries out the real-time monitoring of total organic carbon with the pure water after exchange is handled to hybrid ionic.
This novel purpose is achieved in that a kind of total organic carbon on-line monitoring function ultrapure water machine, comprise that the polypropylene filter, reverse osmosis membrane processing device, mixed ion exchanger and the polishing that are connected in turn by pipeline mix bed, central processing unit, display unit, hybrid ionic treater outlet pipeline is provided with the total organic carbon detection probe, and the output signal of this detection probe is delivered to described central processing unit after the A/D converting unit.
The beneficial effects of the utility model are:
1, the TOC (total organic carbon) to pure water carries out on-line real time monitoring, and reflects by instrument.
2, the TOC in the pure water has been carried out on-line monitoring, allowed the user constantly can both carry out the assurance on the amount, thereby guaranteed to produce qualified water the content of TOC in the water.
