Description
A kind of online turbidimeter detecting device that relates to the water quality measurement field belongs to online turbidimeter parts.
Turbidity is the impurity such as suspension, colloidal material and microorganism of different sizes, density, shape in the water produce effect (light scattering) to light an expression language.Turbidity is one of most important physical appearance index of expression water quality, also is the important evidence of examination water treatment facilities purification efficiency and water technology state.There is substantial connection in organic content in the turbidity of water and the water, and the disinfection rate of water is also had a direct impact.Therefore, it is most important that the turbidity of water detects particularly online detection, and the online turbidimeter of exploitation function admirable also is the inevitable requirement of water technology development.
The weak point of existing online turbidimeter detecting device is: the light that photoelectric cell absorbs not exclusively is scattered light (the part transmitted light is arranged), so that the turbidity of surveying does not meet the original definition of turbidity, so the data deficiency comparability of surveying, inconvenience exchanges; In the online turbidimeter operational process, because of the long-term continuous stream of water sample through opacity tube and optical window, its inwall is polluted by turbid grain material very easily and has a strong impact on the stability of instrument and the accuracy of measurement, so instrument must have the function of removing this dirt.Existing simple ultrasonic cleaning only can make the weak dirt of most of adhesion become flexible and be taken out of by current, and because of belonging to intermittently reset mode, the dirt of those strong adhesions can accumulate gradually; Because of TWS, pressure change gas dissolved water is separated out, the bubble of separating out make instrument that drift phenomenon easily take place, so water sample must remove bubble before detecting attached to causing false turbidity in the detecting device.Existing turbidimeter generally adopts the dividing plate that some is set in the current road, make the bubble emptying, prevents false turbidity.The shortcoming of this de-bubbled technology is: dividing plate still can adhere to bubble, when current generation minor fluctuations, the micro-bubble that adheres to can be brought into detecting device inside attached to opacity tube or optical window on, cause drift phenomenon.
It is a kind of simple in structure that the purpose of this utility model is to provide, and has air, the compound automatic cleaning function of ultrasound wave, can satisfy turbidity and detect requirement, sensitivity, the online turbidimeter detecting device that accuracy of detection is high.
The purpose of this utility model is realized by following technical scheme: a kind of online turbidimeter detecting device, it comprises housing 1, light source 2 is set in housing 1, optical window 3, opacity tube 5, photoelectric cell 4, vibrating membrane 6, ultrasonic generator 7, water sample water inlet 8 is set on housing 1, overflow vent 9, water sample water inlet 8, opacity tube 5 and overflow vent 9 are connected, its special character is: photoelectric cell 4 is contained within on the perisporium of opacity tube 5, vibrating membrane 6 places the lower end of opacity tube 5, ultrasonic generator 7 places the lower end of vibrating membrane 6, waste discharge mouth 10 is set on housing 1, and overflow vent 9 also is an air intake.
The advantage applies of online turbidimeter detecting device of the present utility model exists:
1, because photoelectric cell is included in than around the turbid outside, can absorb and the incident light whole scattered lights of turbid matter (no transmitted light absorbs) at an angle of 90, meet the original definition of turbidity, the result is convenient to comparison and is exchanged, and satisfies turbidity and detects requirement;
2, owing to have air, the automatic compound cleaning function of ultrasound wave, make attached to the water sample that the dirt on opacity tube and the optical window comes off fully and quilt flows by air bump rinse operation and sonic oscillation and take detecting device out of, can fundamentally remove snaking;
3, since the design water sample from top to bottom from the opacity tube evacuation structures, make air enter opacity tube from the air intake on detecting device top because of negative pressure, remove micro-bubble by air bump rinse operation attached to opacity tube and optical window water side, eliminated false turbidity phenomenon, avoided " drift " of online turbidimeter, its sensitivity, accuracy of detection height, good stability.
4, simple in structure, make easily, cost is low.
The utility model is described in further detail to utilize drawings and Examples below.
Fig. 1 is online turbidimeter detector arrangement cross-sectional schematic.
With reference to Fig. 1, online turbidimeter detecting device has housing 1, and housing 1 is divided into three sections and links into an integrated entity by clamping cap 19,13 and sealing gasket 18,11.Overflow vent 9 is set in the upper casing of housing 1, and overflow vent 9 also is an air intake, and light source 2 and the optical window 3 that links to each other also are set, and with pressure cap 16 maintenances, is provided with the power lead hole 17 of light source 2 on pressure cap 16.In the middle piece housing of housing 1, opacity tube 5 is set, photoelectric cell 4 is set on the perisporium of opacity tube 5, the power lead hole 20 of photoelectric cell 4 is set on middle piece housing.Vibrating membrane 6, ultrasonic generator 7 are set in the following piece housing of housing 1, vibrating membrane 6 usefulness pressure caps 12 compress, on the piece housing water sample water inlet 8 and waste discharge mouth 10 are being set down, waste discharge mouth 10 is connected with solenoid valve 14, and the power lead hole 15 of ultrasonic generator 7 is set on following piece housing.
During online turbidity sensors work:
1, water sample enters the opacity tube 5 from the water inlet 8 of online turbidimeter detecting device, discharges through overflow vent 9.From the water sample of light beam in optical window 3 projects opacity tube 5 downwards that monochromatic source 2 is sent, be arranged on whole scattered lights and the corresponding electric signal that is transformed into that opacity tube 5 photoelectric cell 4 on every side receives 90 ° of directions of suspension absurd creature in the water, scattered light intensity is directly proportional with turbidity in the water sample, provides the water sample turbidity value by display.
2, the each measurement finishes, and starts ultrasonic generator 7.Detecting device is carried out cleaned by ultrasonic vibration, make attached to the dirt on opacity tube 5 and the optical window 3 and come off, open solenoid valve 14 dirt and the water that split away off are discharged from waste discharge mouth 10, air is from overflow vent 9 simultaneously, and promptly air intake sucks automatically to opacity tube 5 and optical window 3.Carry out air bump rinse operation, dirt is taken out of from waste discharge mouth 10 by water, and other less debris before measuring next time, and water sample is full of opacity tube 5 once more, is taken out of from overflow vent 9, after measuring, repeats the above-mentioned compound process that washes down.By this compound cleaning process that hockets, can guarantee that opacity tube 5 and optical window 3 are in bright and clean state all the time, guarantee the accuracy of turbidimetry.
3, air is from overflow vent 9, and promptly air intake enters detecting device automatically, washes away the water side of opacity tube 5 and optical window 3, the micro-bubble that adheres to is come off enter gas phase, thereby eliminate the generation of the false turbidity phenomenon that scattering of light is caused because of micro-bubble.
