Description
Technical field
The invention belongs to engineering detecting field, be specifically related to a kind of device of measuring desulfuration chimney corrosion height for thermal infrared imager.
Background technology
China's coal-burning power plant's major part has all adopted wet fuel gas desulfurizing technology, and the smoke moisture after desulfuration absorbing tower approaches state of saturation, and flue gas is pressure drop when chimney rises, and it is saturated that adiabatic expansion makes flue gas cools down reach hygrometric state.The saturated wet flue gas of heat touches colder inner wall of stack and forms condensation product, in the condensation product that flue gas after desulfurization forms, comprises sulfuric acid, sulphurous acid, chloride, fluoride etc., and inner wall of stack has been produced to serious corrosion, and its corrosion class is deep-etching.The seriously corroded of chimney wall has affected the security of structure; it is the in the situation that of compressor emergency shutdown that traditional chimney is detected by extent of corrosion; adopt the method for unbearable sampling to detect; not only damage chimney lining anticorrosive coat; and affect the normal operation of genset, because testing on-site sampling exists more work high above the ground link, have a big risk, dangerous high; and an on-the-spot sample analysis of experiments time in later stage is longer, whole process is consuming time, effort.Adopt infrared thermography in the situation that not affecting production, to the corrosivity of chimney wall, to detect, and calculate and can provide quantitatively its corrosion thickness by thermal technology.
Common infrared thermography is when carrying out chimney corrosivity monitor, thermal imaging system is taken on ground, because chimney height inconvenience accurately identifies, in later stage photo disposal, be difficult to accurately determine thermography residing particular location on chimney wall, and in shooting process, because the shake of hand-held thermal imager is larger, can affect thermographic shooting quality, to graphical analysis, bring many difficulties.
Summary of the invention
Technical barrier to be solved in the utility model is height identification difficulty, easy shake etc. in existing thermal imaging system use procedure, object is to provide a kind of thermal infrared imager support, can facilitate thermal imaging system vertical rotating, and with rotational angle display disc, to reach convenient and practical, data read object efficiently.
Technical matters to be solved by this invention is achieved through the following technical solutions:
A kind of device of measuring desulfuration chimney corrosion height for thermal infrared imager, comprise tripod (10), be located at the top board (9) on described tripod (10), it is characterized in that: described top board (9) is provided with vertical supporting bar (5), described vertical supporting bar (5) is fixed with fixedly montant (6) of index dial (1), rotatable dial needle (2) and thermal imaging system by turning axle (3); Described dial needle (2) matches with described index dial (1).
Described thermal imaging system fixedly montant is provided with fixedly snap close (7) of thermal imaging system.
Described top board (9) is provided with magnet base (8), and described magnet base (8) is provided with magnet base switch (4).
Described index dial (1) is round-meshed off-centre operation.
The utility model adopts the technique scheme effect that possesses skills:
The utility model can accurately calculate the height of thermal imaging system camera site according to the distance between measuring point and chimney, and this framework construction is reasonable, uses simply, can assist easily and efficiently the infrared thermal imaging Detection task of desulfurization fume corrosion chimney wall.

Fig. 4 is the eccentric circle diagram of index dial of the present utility model
Wherein, 1-index dial, 2-dial needle, 3-turning axle, 4-magnet base switch, 5-vertical supporting bar, 6-thermal imaging system is montant fixedly, and 7-thermal imaging system is snap close fixedly, 8-magnet base, 9-top board, 10-tripod.11-circular hole
Embodiment
Shown in Fig. 1, Fig. 2 is a kind of device of measuring desulfuration chimney corrosion height for thermal infrared imager, index dial 1 is angle scale, a circular hole (11) is arranged at top, make index dial 1 form an eccentric wheel, when index dial is adjusted around turning axle 3 under Action of Gravity Field like this, can guarantee that described index dial 1 zero angle is horizontal direction all the time, to carry out measurement of angle.Dial needle 2 and turning axle 3 and thermal imaging system fixedly montant 6 are fixed together, and guarantee that thermal imaging system rotates, and described dial needle 2 follows described thermal imaging system to turn an angle together.Magnet base 8 is mainly convenient to dismantle, and runs into the situation of the comparatively narrow or inconvenient mensuration of environment, can by spin magnetization seat switch 4, be unloaded and be got bracket head at any time, to be placed to suitable position, carries out thermal imagery mensuration.Thermal imaging system fixedly montant 6 and thermal imaging system fixedly snap close 7 be mainly fixedly thermal imaging system effect so that safety is installed thermal imaging system securely.Described tripod 10 can stretch and pack up, and is easy to carry.
Using method of the present invention is, first fixing the utility model thermal imaging system support measures the distance L of chimney and carriage center.Utilize thermal imaging system to carry out thermography shooting to chimney, record the corresponding angle value θ on thermography numbering and described angle scale.According to trigonometric function, the position height h that takes thermography chimney wall of living in is: the distance of chimney and carriage center is multiplied by the tangent value of shooting angle, if support height is made as H, and actual h=H+Ltan θ.Utilize this device, by above-mentioned steps, can complete the thermographic accurate location of chimney.
