Description
Technical field
The utility model relates to boiler exam technical field, is specially a kind of boiler cold-state aerodynamic field on-line measurement device.
Background technology
The stability that boiler controller system runs and economy depend on the combustion conditions in stove to a great extent, and the performance-critical of combustion conditions depends on the aerodynamic field operating mode of burner and burner hearth, good aerodynamic field operating mode is very large on the impact of stove combustion, so the Actual combustion of the aerodynamic field of coal-fired plant boiler to boiler has very important meaning.
Cold test can eliminate the defect of burner aspect, inquires into the characteristic of burner and jet, thus carries out pre-adjustment to burner, points the direction and reduce blindness and the experiment work amount of hot adjustment for boiler thermal-state firing optimization.Not only can determine degree of uniformity, the flow dynamic characteristic of combustion system according to the characteristic of burner and jet, can also determine to affect the various factors of boiler degree of filling and the aerodynamic field mechanism of slagging.
In order to judge the advantage of the aerodynamic field operating mode of burner hearth, just need to carry out test observation, record to it, this hot be difficult to realize, the method that usual employing cold-stat e simulation is hot, that is: in the cold state, by certain requirement, burner hearth is ventilated, the flow condition of air-flow in observation burner hearth, so-called cold air dynamic field test that Here it is.Cold air dynamic field test observation method mainly comprises: ribbon method, fireworks trace method, mensuration and Computer Numerical Simulation method, wherein: ribbon method, fireworks trace method can measure the direction of air-flow, but cannot draw the size of speed.Computer Numerical Simulation method is a complete field in computational fields by calculating combustion field, speed, pressure, temperature Anywhere in computational fields can be shown, or the regularity of distribution in whole region, but accuracy is difficult to determine, mensuration utilizes pitot tube and anemoscope etc., velocity field in measuring point burner jet and stove, mensuration can only measure the absolute value of gas velocity, can not measure the direction of air-flow, it is the most frequently used method that usual mensuration and ribbon method or fireworks trace method etc. combine.
Mensuration workload is very huge, utilize pitot tube or anemoscope measuring wind, the burner outlet of personnel in boiler is often needed to measure, and burner is higher at the absolute altitude of boiler, environment very severe simultaneously in boiler, burner outlet in boiler carries out measuring more dangerous, and when measuring, instrument is exposed in the environment of band ash, makes measurement often not accurate enough.And ribbon method and fireworks trace method often need take a picture, in order to reach full effect of clapping, also needing staff to take from boiler higher position, also there is very large danger.
At least there is following technical matters in prior art:
In prior art, adopt the mode that the mensuration of artificial enforcement and ribbon method or fireworks trace method combine, the longer time often will be spent to have gone, and in actual mechanical process, staff manually cannot the height of location survey instrument accurately, cause that measuring accuracy is lower, the test period is long, certain threat is formed to the safety of personnel simultaneously.
Summary of the invention

The utility model solves the technical scheme that its technical matters adopts:
A kind of boiler cold-state aerodynamic field on-line measurement device, it includes cruciform guide rail, rectangular guideway, support, dolly, control system, 360 degree of camera heads.Cruciform guide rail is connected with rectangular guideway to be set up on boiler maintenance platform in sphere of movements for the elephants shape, and Bracket setting is below rectangular guideway four end points places, and support is adjustable support, and rail brackets can carry out height control as required.Control system comprises controller and data collecting instrument, dolly is fixedly installed drive motor and measurement mechanism, and dolly can along guide rail movement under drive motor effect, and drive motor and measurement mechanism are connected with controller, and measurement mechanism is also connected with data collecting instrument; Camera head is fixed on place of cruciform guideway centreline by support, and camera head is connected with data collecting instrument and controller.
Rectangular guideway is provided with four dollies, every bar rectangular edges arranges one, cruciform guide rail is arranged four dollies.
Camera head place is provided with LED illuminator, and camera head comprises camera and angle adjustable rack.
Data collecting instrument is provided with pc port, can be connected with computing machine.
Operating process of the present utility model is: under control system manipulation, and dolly drives the measurement mechanisms such as measuring wind speed instrument to run on guide rail, the time that the Distance geometry that its method of operation can set movement as required stops.360 degree of camera heads can as test platform positioning function, and can monitoring test situation in real time; The multiple stage wind speed tester device that cruciform guide rail and rectangular guideway run, be connected to data collecting instrument by data line, data collecting instrument is connected with computer, and Real Time Observation test data also carries out data processing.
The beneficial effects of the utility model are: compare existing manual testing's method, and testing tool is fixed a point on guide rail, timed motion to utilize control system to drive, and realizes the test job of aerodynamic field data, measuring accuracy is high, the test period is short, easy-to-operate.
