A remote operation control system of a crane for delayed coking

Abstract

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. Including a coordinate detection system for detecting the traveling direction of the trolley and trolley on the crane; a camera system for monitoring the running status of the crane; a radar level sensor for scanning the coke pool to obtain information on the thickness of coke accumulation inside the coke pool; A rotary encoder used to detect the vertical displacement of the grab bucket of the crane, the rotary encoder is installed on the pulley block of the control trolley; a tension sensor used to detect the weight of the material grabbed by the grab bucket of the crane, one end of the tension sensor is fixed On the trolley, the other end is connected to the wire rope carrying the trolley; the remote controller is used to remotely control the operation of the crane, and the remote controller is connected to the PLC of the crane. The invention is capable of remote control, so that operators can accurately control the grab crane without being in harsh 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 delayed coking crane. Background technique [0002] Delayed coking is a thermal cracking process. Its main purpose is to convert residual oil with high residual carbon into light oil. The equipment used can be cyclically operated, that is, the heavier fraction in the coking distillate of heavy oil is used as circulating oil. The residence time in the device is longer. Delayed coking is a treatment process with the most serious pollution in oil refineries. For example, in hydraulic decoking, the coke produced is generally stored in the open air. A large amount of coke powder, oil and gas, and water vapor have extremely bad effects on the surrounding environment and usually affect on-site operators. Cause great damages, but also cause great environmental pollution. With the large-scale delayed coking unit and...

Problems solved by technology

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
