Remote operation control system of overhead traveling crane for delayed coking

Abstract

The invention relates to an operation control system of a hydraulic-decoking overhead travelling crane for delayed coking, in particular to a remote operation control system of an overhead travelling crane for delayed coking. The remote operation control system comprises a coordinate detecting system, a camera system, radar material level sensors, rotating encoders, tension sensors and a remote controller. The coordinate detecting system is used for detecting running directions of large cranes and small cranes on the overhead travelling crane. The camera system is used for monitoring operation conditions of the overhead travelling crane. The radar material level sensors are used for scanning a coking pool to acquire stacking thickness information of coke in the coking pool. The rotating encoders are used for detecting displacement of grab buckets of the overhead travelling crane in the vertical direction. The rotating encoders are mounted on pulley blocks of the small cranes. The tension sensors are used for detecting weight of materials grabbed by the grab buckets of the overhead traveling crane. One ends of the tension sensors are fixed on the small cranes while the other ends of the same are connected with steel wire ropes supporting the small cranes. The remote controller is used for remotely controlling operations of the overhead travelling crane and is connected with a PLC (programmable logic controller) of the overhead travelling crane. Remote control can be realized by the operation control system, so that operators can accurately control grab cranes while being away from severe environments.

Description

technical field [0001] The invention relates to a hydraulic decoking crane operation control system for delayed coking, in particular to a remote operation control system for a delayed coking crane. Background technique [0002] Delayed coking is a thermal cracking process, the main purpose of which is to convert high-carbon residual oil into light oil, and the equipment used can be used for recycling operations, that is, the heavier fraction of the coking distillate oil of heavy oil is used as circulating oil. The residence time in the device is longer. Delayed coking is one of the most polluting treatment processes in refineries. For example, in hydraulic decoking, the coke produced is generally stored in the open air. A large amount of coke powder, oil gas, and water vapor have extremely bad effects on the surrounding environment, and are usually harmful to on-site operators. It will cause great damage, and also cause great environmental pollution. With the scale-up of d...

Delayed coking is one of the most polluting treatment processes in refineries. For example, in hydraulic decoking, the coke produced is generally stored in the open air. A large amount of coke powder, oil gas, and water vapor have extremely bad effects on the surrounding environment, and are usually harmful to on-site operators. It will cause great damage, and also cause great environmental pollution. With the scale-up of delayed coking units and the improvement of the status of such units in the refining process of oil refineries, how to reduce the harm of the working environment to operators and reduce the environment Pollution is an urgent problem that needs to be improved in this unit, and it is one of the key issues restricting the development of delayed coking units
