Abstract
The utility model discloses a chemical dosing mixer for water treatment, which comprises a chemical dosing pipe, a metering pump, a controller and two conductivity gauge probes, wherein the metering pump is arranged on the chemical dosing pipe and is connected with the controller through a cable, and the two conductivity gauge probes are respectively connected with the controller. The conductivity of water at a water inlet and a water outlet is measured through the conductivity gauge probes, the added amount of NaOH is determined by the controller according to the measured conductivity, and the NaOH is added by controlling the frequency of the metering pump. Therefore, the chemical dosing mixer can sensitively make a response, can realize accurate control and can be frequently used without being calibrated.
Description
Technical field
The utility model relates to the water treatment chemicals dosing plant, is specifically related to a kind of NaOH dispensing mixing tank.
Background technology
In PREPARATION OF ULTRA-PURE WATER, adopt reverse osmosis membrane that former water is carried out advanced treatment usually; Because it is acid that the reverse osmosis membrane water outlet shows, bicarbonate radical is instability when PH is low, easily resolves into CO
2Gas exists, and reverse osmosis membrane is 0 to the clearance of gas, if enter back level pure water case, can cause electrical conductivity of water to rise, and corrodibility increases.At this moment, generally need to add NaOH solution, reverse osmosis is gone out water ph value regulate.
At present, be to adopt PH to count the pH value that detects the reverse osmosis water outlet, feed back to system, by the addition of system-computed and definite NaOH.There is following shortcoming in this mode: 1, system can not be accurate, and the NaOH addition what know fast, and reaction sensitivity is slow; 2, PH counts each use all needs to demarcate complex operation.
The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, the water treatment dispensing mixing tank that provides a kind of very sensitive to detect the NaOH addition, and also this dispensing mixing tank can easily frequently use, and do not need demarcation.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
A kind of water treatment dispensing mixing tank, described dispensing mixing tank comprises chemical feed pipe, volume pump, controller and conductivity meter probe, and described volume pump is arranged on the chemical feed pipe, and this volume pump connects controller by cable, described conductivity meter probe is two, and is connected with controller respectively.
Described chemical feed pipe is a U type pipe.
With respect to prior art, the utlity model has following advantage:
1, the specific conductivity by conductivity meter probe measurement water-in and water outlet is determined the addition of NaOH by controller by the difference of measured specific conductivity, controls the frequency of volume pump and adds NaOH, is quick on the draw precise control;
2, the utility model NaOH dispensing mixer structure is simple, can frequently use and does not need to demarcate.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, 1 is medicine-chest, and 2 is chemical feed pipe, and 3 is volume pump, and 4 is cable, and 5 is controller, and 6 are the conductivity meter probe, and 7 is water pipe.
Embodiment
Below in conjunction with the drawings and specific embodiments structure of the present utility model is described in further detail.
Referring to as Fig. 1: the utility model water treatment is with the dispensing mixing tank, comprise chemical feed pipe 2, volume pump 3, controller 5 and conductivity meter probe 6, volume pump 3 is arranged on the chemical feed pipe 2, and this volume pump 3 connects controller 5 by cable 4, conductivity meter probe 6 is two, and is connected with controller 5 respectively.
During use, one end of dispensing mixing tank chemical feed pipe 2 leads to NaOH medicine-chest 1, the other end is connected with water pipe 7 by Y-tube, the tie point of chemical feed pipe 2 and water pipe 7 is between two conductivity meter probes 6, chemical feed pipe 2 is a U type pipe, two conductivity meter probes 6 detect the specific conductivity of water-in and water outlet respectively, to detect data and send controller 5 to, whether controller 5 calculates and control NaOH by the specific conductivity difference of water-in and water outlet adds, and the frequency of control volume pump 3 is controlled the additive capacity of NaOH.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
