Device and method for maintaining safe operation of water cooler with internal leakage

Abstract

The invention provides a device and method for maintaining safe operation of a water cooler during leakage (internal leakage) of a pipe bundle of the water cooler. The device comprises the water cooler, a pipeline pump and a liquid separation pot, wherein the water cooler is provided with a circulating water inlet, a circulating water outlet, a process medium inlet and a process medium outlet, thecirculating water inlet and the circulating water outlet both communicate with a circulating water source, the process medium inlet communicates with a process medium source, and a first valve is installed on a first pipeline; the pipeline pump and the first valve are installed in parallel; and the liquid separation pot is provided with a process medium inlet and a process medium outlet, the process medium outlet of the water cooler communicates with the process medium inlet of the liquid separation pot, and the process medium outlet of the liquid separation pot communicates with the processmedium source. Through the device and method, circulating water quality deterioration, high operation cost and possible potential safety hazards caused by leakage of the pipe bundle of the water cooler are avoided, the service life of the crucial water cooler of the device can be guaranteed, the operation period of the device is prolonged, and an important technological means is provided for guaranteeing long-period operation of the oil refining and chemical engineering device.

Description

technical field [0001] The invention relates to the technical field of oil refining and chemical equipment, in particular to a device and method for maintaining safe operation of a water cooler when the water cooler leaks internally. Background technique [0002] In refinery and chemical plants, due to corrosion on the process medium side and water side, the tube bundle of the water cooler will leak. After a leak occurs, for water coolers that can be isolated from the system for maintenance without causing a major impact on normal production, a plan to stop maintenance is adopted; for those that are difficult to isolate from the system, stop maintenance (or stop maintenance from the system Large economic losses) water coolers (such as catalytic cracking units, interstage coolers of delayed coking unit air compressors, etc.) need to adopt reliable technical means to continue to maintain their safe and stable operation until the normal maintenance of the units.

Problems solved by technology

[0003] However, at present, for water coolers that are difficult to isolate from the system for shutdown and maintenance (or shutdown and maintenance from the system have great economic losses), the technical means to maintain their safe and stable operation are not yet mature, so it is necessary to propose a Device and method for maintaining safe operation of water cooler when water cooler leaks
