Automatic detecting system for detecting coke thickness by hydraulic decoking

Abstract

The invention provides an automatic detecting system for detecting coke thickness by hydraulic decoking, consisting of a computer, a dynamic signal analyzer, a PLC (programmable logic controller), a proximity sensor and 4-6 vibration sensors; the vibration sensors are arranged on the external wall of a coke tower at intervals by an assembling bracket in the vertical direction; the vibration sensors are connected with the dynamic signal analyzer by signal cables; the proximity sensor is arranged at one side of a lifting mechanism of the decoking device; an induction block is arranged on the lifting mechanism; the proximity sensor is connected with the PLC by the signal cables; and the dynamic signal analyzer and the PLC are connected with the computer respectively. The automatic detecting system has the advantages of automatically detecting the removal situation of cokes in the coke tower, reducing the labor intensity of a worker and improving the automation level of a device. The assembling bracket of the vibration sensors can be quickly assembled so that the service life of the sensors can be prolonged.

Description

technical field [0001] The invention relates to a detection device for hydraulic decoking of a delayed coking device in the petrochemical industry, in particular to an automatic detection system for hydraulic coke cutting coke thickness. Background technique [0002] At present, during the hydraulic coke cutting process of the device, the operator generally relies on the operator to continuously observe the coke cutting water in the chute exiting from the bottom of the tower, and judge whether the coke in the coke tower is cut clean according to work experience. The distance between the chute and the observation window is about 40 meters. Due to changes in the weather, the operator cannot observe accurately in foggy weather, which affects the progress of coke cutting. With the shortening of the coke generation cycle, the operator needs to cut the coke at night, and the vision is not good , which affects accurate observation, and then affects the focus cutting process.
