Description

TECHNICAL FIELD

[0001] The utility model relates to a boiler technical field, especially a kind of boiler inner wall coking and temperature measuring device. BACKGROUND

[0002] At present, the observation of the coking condition in the furnace of a boiler is mostly carried out by manual observation, i.e., the coking condition in the furnace is observed through the observation hole by naked eyes. Under normal circumstances, the inside of the furnace of a boiler is in a negative pressure environment, but the negative pressure in the furnace of a boiler is unstable, and if the coking in the furnace of a boiler occurs, positive pressure may appear in the furnace of a boiler, and in serious cases, flames may be spouted out from the observation hole. When the coking condition is directly observed by naked eyes, in order to ensure personal safety, protective goggles, protective masks and other protective articles need to be worn, so that the observation of coking is not conducive to the observation of the surrounding working environment, and once danger occurs, it is not conducive to personal avoidance. In addition, direct observation by naked eyes cannot observe the overall coking of the inner wall of a boiler, but only a small part of the coking condition of the inner wall can be observed, which may cause blind area coking to be unable to be predicted, and the coking condition in other areas of the furnace cannot be grasped, which may cause major production accidents. Therefore, how to ensure comprehensive observation of the inside of a boiler under the condition of ensuring the safety of the observer is a problem that needs to be considered by those skilled in the art.

[0024] The content of the utility model will be further described in detail in combination with specific embodiments:

[0025] As Figures 1-5 shown, the utility model is applied to the observation of the coking condition of the inner wall of a boiler. The measuring device is sent into the interior of the boiler through the observation hole, and the inner wall around the observation hole is photographed through rotation, forming a hexagonal area with the observation hole as the center. After observation at several different observation holes, a grid is formed, which can basically cover the entire area inside the boiler. Specifically:

[0026] A coking and temperature measuring device for the inner wall of a boiler, comprising a connecting device 1 arranged on the outside of the boiler, and a measuring mechanism 2 connected with the connecting device 1 and capable of being inserted into the boiler through an observation hole on the boiler. The measuring mechanism 2 comprises a protective device 21 provided with a window, a measuring device 22 arranged inside the protective device 21, and an adjusting device 23 connected with the measuring device 22, the adjusting device 23 being connected with the connecting device 1 at the same time; the connecting device 1 drives the protective device 21 to be inserted into the boiler from the observation hole through the adjusting device 23, and the measuring device 22 is used for observation and measurement.

[0027] The connecting device 1 comprises a support frame 11 fixedly arranged on the outside of the boiler, and a drive device 12 connected with the support frame 11, the drive device 12 being connected with the measuring mechanism 2 through the adjusting device 23 and capable of driving the measuring device 22 to be inserted into or withdrawn from the boiler. In this embodiment, the support frame 11 can be arranged on the outer wall of the boiler, or on a separate device relative to the boiler; the drive device 12 can be driven by a motor or started by a pneumatic cylinder, and the driving direction thereof is the horizontal direction.

[0028] The adjusting device 23 comprises a rotating device 231 connected with the shielding device 21 and capable of driving the shielding device 21 and the measuring device 22 to rotate. The rotating device 231 can be a rotating motor or a rotating cylinder, which can drive the measuring mechanism 2 to rotate 60 degrees each time to collect the overall image information of the circumferential area of the observation hole by the measuring device 22; when the measuring mechanism 2 extends into the boiler, the adjusting device 23 is located outside the boiler, and the side of the adjusting device 23 close to the boiler shields the gap between the observation hole and the shielding device 21, thereby reducing the risk of flame spouting out of the boiler.

[0029] The measuring device 22 comprises a camera assembly 221 and a mirror 222 arranged close to the window 216, and the camera assembly 221 can collect the image information outside the window 216 through the mirror 222. The shielding device 21 comprises an outer shell 211, an inner shell 212 arranged inside the outer shell 211, and a fixing block 213, and the fixing block 213 and the inner shell 212 form a first cavity 21a in which the measuring device 22 is arranged; a second cavity 21b is formed between the inner shell 212, the outer shell 211 and the adjusting device 23, and the second cavity 21b is provided with a water inlet pipe 214 and a water outlet pipe 215. The window 216 comprises a first opening arranged on the inner shell 212 and a second opening arranged on the outer shell 211, and the first opening and the second opening are both provided with high-temperature-resistant glass.

[0030] In the embodiment, the first opening and the second opening can adopt a coincident design and share a piece of high-temperature-resistant glass, so as to avoid the influence of the cooling liquid flowing between the first opening and the second opening on image collection. The cooling liquid enters the second cavity 21b through the water inlet pipe 214 and flows in the second cavity 21b to cool the outer shell 211 and is discharged through the water outlet pipe 215. The camera assembly can adopt an infrared camera, which can obtain temperature information while collecting the focused image.

[0031] In the embodiment, during observation, the observation mechanism is driven by the driving device 12 to extend into the inside of the boiler through the observation hole; then the measuring device 22 is driven by the rotating device 231 to rotate 60 degrees each time to collect the image information of six areas around the observation hole respectively and form a whole; then the image collection is sequentially performed through other observation holes, and all the image information is connected as a whole, so that the overall image information of the inner wall of the boiler can be obtained, and the coking condition of the inner wall can be analyzed.
