Embodiment 1

[0046]The basic information and testing equipment information of the coke drum tested are shown in Table 1. The coke drum was internally inspected in 2016. The maximum inner diameter measured by physical measurement method was 6300mm, the designed inner diameter was 6100mm, and the inner diameter increased by about 200mm. However, the deformation amount and position obtained by this detection method are relatively rough.

[0047] Table 1 Basic parameters of coke drum detection

[0048]

[0049] Since there is no actual measurement data of the original size of the coke drum, a three-dimensional model of the undeformed coke drum is established with reference to the design structure size.

[0050] This method is used to detect the coke drum, and the point cloud data of the deformed coke drum body obtained according to the actual measurement results is compared with the three-dimensional model of the undeformed coke drum. The result is as figure 1 shown. Depend on figure 1 ...

Abstract

The invention discloses a three-dimensional laser scanning detection method for the deformation of a coke tower cylinder, which comprises the following steps: (1) preparation before detection; (2) connection between a scanner and a nozzle of a coke cutter; (3) detection parameters and remote control setting ;(4) Enter the coke tower for scanning and detection; (5) Take out and disassemble and confirm the results; (6) Generate point cloud data of the deformed coke tower body; (7) Establish point cloud data or three-dimensional model of the undeformed coke tower; (8) Coke tower deformation and deformation position analysis.

Description

technical field [0001] The invention relates to a detection method for the deformation and damage of the coke tower equipment cylinder of the delayed coking device in the petrochemical field, more particularly, it refers to a detection technology based on three-dimensional laser scanning, which can detect the cylinder deformation of the coke tower equipment in service on-line method for rapid detection. Background technique [0002] The coke tower is the key equipment for producing coke in the refinery. Its production process is a delayed coking process, and its function is to provide thermal decomposition and comprehensive reaction sites for raw materials. The operating conditions of the coke drum are harsh, and it is a pressure vessel subjected to thermomechanical stress cycles. Generally speaking, the entire operation period of the coke tower is 24-48 hours. The process flow of the coke tower includes four stages: steam heating, oil filling, water cooling and decoking. ...
