Description
Technical field
The utility model relates to a kind of water quality pH intelligence sensor.
Background technology
Water quality detection is the basis of water treatment system, just can carry out on the basis that water treatment must detect at the every monitoring index to water quality.Common detection index comprises: pH value, colourity, five-day BOD, chemical oxygen demand (COD), formaldehyde, phenyl amines, nitrobenzene etc.
For the detection of pH value, normally complete by pH value sensor at present.The measuring process of common pH value sensor: utilize electrode sensor to measure pH in aqueous solution, sensor is by glass point set calomel (or silver, silver chloride) battery of contrast electrode composition can produce the potential difference (PD) relevant to pH according to Nernst equation.The electrode of sensor is connected with pH value instrument, the potential difference (PD) that realization detects and the conversion between pH.
PH value sensor of the prior art is generally all made the blister glass electrode with silica glass material, and its stain resistance is poor, and physical strength is low, is unsuitable for the continuous monitoring to water quality.Particularly in sewage disposal process, pH is very strict to the requirement of sensor in the on-line continuous monitoring, and sensor must satisfy following requirement: structure wants firm and durable, stable testing safe and reliable, and stain resistance is strong, noiseless, pollution-free to test environment.
The utility model content
It is a kind of to test environment is noiseless, reliability and durability, physical strength is high and the pH sensor of long service life that the purpose of this utility model is to provide, and this pH sensor can be used for the continuous on-line monitoring to the pH value of water quality.
For achieving the above object, the utility model adopts following technical scheme:
A kind of water quality pH intelligence sensor, described sensor comprises electrode shell body, contrast electrode, test electrode and electrode outlet line, it is inner that described test electrode and contrast electrode are arranged on the electrode shell body; Described electrode shell body rear end is provided with interface extraction electrode extension line; Described sensor also comprises battery.
The utility model pH sensor is provided with battery, and when externally power supply broke down, this battery can be used as the standby power supply of salinity sensor, to guarantee the continuous monitoring to water quality.
Preferably, the test electrode of described sensor arranges screen pack outward, and sleeve is set outside screen pack, and sleeve is fixed on screen pack outside the test electrode of sensor head, and the outer circumference surface of sleeve evenly is provided with through hole.
Because sensor head is provided with screen pack and sleeve, the solid particle during test in water does not contact with test electrode, therefore, can not produce precipitation and incrustation, and stain resistance is good.
Preferably, described sensor also comprises the temperature sensing module.
Because the current potential of contrast electrode can change along with the variation of temperature, therefore can cause the contrast electrode potential stability can be poor.The utility model pH sensor has increased the temperature sensing module, makes the pH of the measured object that can cause temperature in test change and compensates, and makes measurement result more accurate.

Embodiment
With reference to attached Fig. 1 and 2, a kind of water quality pH intelligence sensor, described sensor comprise electrode shell body 1, contrast electrode 2, test electrode 3 and electrode outlet line 4, and described test electrode 3 and contrast electrode 4 are arranged on electrode shell body 1 inside; Described electrode shell body 1 rear end is provided with interface extraction electrode extension line 4, and electrode shell body 1 is the carbon fibre resin shell, and described test electrode 3 is the cobalt nitride electrode; Described sensor also comprises battery 9.
PH outer sensor housing 1 adopts carbon fibre resin to make, so pH sensor decay resistance is very good, sturdy and durable, can not exert an influence to test environment; And test electrode 3 is metal nitride electrode, and is larger than glass electrode intensity commonly used, is difficult for oxidation, long service life.These characteristics makes the pH sensor to use for a long time, does not need frequent maintenance, can realize the long-time on-line monitoring to water quality.
The utility model pH sensor is provided with battery 9, and when externally power supply broke down, this battery 9 can be used as the standby power supply of salinity sensor, to guarantee the continuous monitoring to water quality.
The outer screen pack 5 that arranges of the test electrode 3 of described sensor head, at the outer sleeve 6 that arranges of screen pack 5, sleeve 6 is fixed on screen pack 5 outside the test electrode 3 of sensor head, and the outer circumference surface of sleeve 6 evenly is provided with through hole 7.
Because sensor head is provided with screen pack 5 and sleeve 6, the solid particle during test in water does not contact with test electrode 3, therefore, can not produce precipitation and incrustation, and stain resistance is good.
Described sensor also comprises temperature sensing module 8.
The pH sensor has increased temperature sensing module 8, makes the pH of the measured object that can cause temperature in test change and compensates, and makes measurement result more accurate.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change and revise above-mentioned embodiment.Therefore, the embodiment that discloses and describe above the utility model is not limited to also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this instructions, these terms do not consist of any restriction to the utility model just for convenience of description.
