Description
Technical field
The present invention relates to performance testing device, especially sewage Laser Measuring test stand.
Background technology
The life of the mankind and production activity all be unable to do without water, the water taken from nature is contaminated owing to having infiltrated various pollutant, change the physics that natural water is original, chemical or biological composition and character, even lose use value, then outer row is discarded, this water going out of use outer row is called sewage. sewage is originated by it, sanitary sewage and the big class of trade effluent two can be divided into, in general, the index of sewage is checked to have following: COD, BOD, colourity, float, heavy metal etc..
Sewage physics parameter test method all uses sensor on-line testing at present, but owing to sewage contains significantly high stickup liquid, have on sensor and be stained with mucus, make sensor lose sensitivity, optic test can at a high speed, detect in real time, be the developing direction of sewage discharge performance test.
Currently without sewage performance parameter is carried out optic test tester and method of testing.
Therefore design sewage Laser Measuring test stand, for grasping its performance parameter thus promoting that the raising of clean-up effect has important meaning.
Summary of the invention
It is an object of the invention to provide sewage Laser Measuring test stand, effluent treatment plant can be detected in real time its clean-up effect, there is safe and reliable, low cost and other advantages.
For achieving the above object, the present invention adopts the following technical scheme that
Sewage Laser Measuring test stand, including the soil pipe being arranged at bilge well exit, the laser sewage detection device being arranged on soil pipe, discharge outlet.Laser instrument, convex lens I, concavees lens II, transparent sensing chamber, lens III and avalanche photodide composition light path it is sequentially provided with in order from top to bottom in described laser sewage detection apparatus housing；Described concavees lens II is arranged on the out-of-focus of convex lens I, and avalanche photodide is arranged on the focal length of convex lens III；Filter amplifier, microprocessor it is provided with after described avalanche photodide；
Described microprocessor, microprocessor are connected with computer with electric cleaner.Described front end laser sewage detection device microprocessor, rear end laser sewage detection device microprocessor are connected with computer with ultrasonic purification device.
Described laser instrument is installed with the mutual correlation of avalanche photodide.
Described described soil pipe and light path are arranged vertically；
Described transparent sensing chamber is rectangular configuration.
Compared with prior art, the invention has the beneficial effects as follows: owing to have employed technique scheme, it is possible to the gauge check to the counting of sewage particle number and size, it is not necessary to change and take manpower and materials collection, and simple in construction, volume are little, can real-time testing, convenient and swift.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
In order to make technical scheme become apparent from, below in conjunction with accompanying drawing 1, the present invention is described in detail.It should be appreciated that the detailed description of the invention described in this specification is only used to explain the present invention, it is not intended to limit protection scope of the present invention.
The present invention is sewage Laser Measuring test stand, including the soil pipe 3 being arranged at bilge well 2 exit, the laser sewage detection apparatus housing 4 being arranged on soil pipe, discharge outlet 13.It is sequentially provided with laser instrument 5, convex lens I6, concavees lens II7, transparent sensing chamber 12, lens III8 and avalanche photodide 9 in order from top to bottom in described laser sewage detection apparatus housing 4 and forms light path, described concavees lens II7 is arranged on the out-of-focus of convex lens I6, and avalanche photodide 9 is arranged on the focal length of lens III8；Parallel connection is set after described avalanche photodide 9 and is connected to filter amplifier 10, microprocessor 11；Described microprocessor 11 is connected with computer 1.
The second described microprocessor 11 is connected with computer 1 with bilge well 2.
Described laser instrument 5 is installed with receiving device avalanche photodide 9 straight line.
Described soil pipe is mutually perpendicular to layout with detection light path.
Described transparent sensing chamber 12 is rectangular configuration.
The operation principle of the present invention is: the sewage discharged in bilge well 2, accesses in laser sewage detection apparatus housing 4, measure sewage content in sewage after soil pipe 3, and data are uploaded to computer 1.Using laser instrument 5 as light source, avalanche photodide 9 is as receptor, the light that laser instrument 5 sends is irradiated to transparent sensing chamber 12 after convex lens I6, concavees lens II7, when the sewage having particulate matter passes through transparent sensing chamber 12, the intensity of light will change, and light is received by avalanche photodide 9 after lens 8, produces the electric impulse signal being in proportion with particulate matter, by filter amplifier 10, microprocessor 11 sampling processing, signal is delivered in computer 1.
Preferably, the present invention adopts correlation type detection mode, and mutual to emitter and receptor correlation is installed, and makes the luminous energy that emitter sends enter receptor.When there being detection object to enter between emitter and receptor, measured object will shield lights and cause that the light quantity entering receptor reduces, just can detect the content of measured object according to the change of receptor light quantity.The method stability is high, response is fast, and the impact that particulate matter is detected by the factor such as the color of object, gloss is smaller.
