Embodiment 1

[0025] Embodiment 1: below by the implementation instance in certain oil refinery, in conjunction with attached figure 2 And attached image 3 The present invention is further described.

[0026] There are two sets of light oil fractionation tower bottom pumps in an oil refinery, one is the main power equipment 1, the main power equipment 1 adopts the lubricating oil cooler of the main compressor, one is the main power equipment 1, and the standby power equipment 2 Adopt spare compressor lubricating oil cooler. The original process is that the main power equipment 1 and the main power equipment 1 are connected in parallel to configure circulating cooling water: the main power equipment 1 is connected to the main pipeline through the main power equipment upper water pipe 5 and the main power equipment return water pipe 6, and the main power equipment upper water pipe 5 and the main power equipment are connected to the main pipeline. The equipment return pipe 6 is respectivel...

Abstract

The invention relates to a method for utilizing cooling water of a host machine and cooling water of a standby machine of power equipment in a cascaded way. The method is applicable to pumps, fans, compressors and other power equipment adopting a circulating water cooling system in the process industry. A crossover pipeline is additionally arranged on host machine and standby machine cooling water feeding and returning pipelines, and the crossover pipeline is connected with original cooling water pipelines through three-way valves to realize two-way cooling water supply. Circulating water is saved, and the situation in which cooling water is cut off and equipment is burnt out due to wrong operation is prevented. By adopting the method of the invention, secondary utilization of cooling water of power equipment is realized, the consumption of cooling water is reduced significantly, the heat of standby power equipment can be preserved in winter, and thus, too low temperature of lubricating oil and the impact thereof on startup are prevented. The method of the invention can be used to optimize and transform the existing power equipment circulating cooling water system and can be directly applied to the links of process design, and has the characteristics of small workload, low cost, and goods benefits.

Description

technical field [0001] The invention belongs to the technical field of energy saving, and relates to a method for cascadingly utilizing the cooling water of a main engine and a standby power equipment, which is suitable for power equipment such as compressors, fans, pumps and the like which use circulating cooling water in the process industry. Background technique [0002] Pumps, fans, compressors and other power equipment are common equipment in the process industry. The main components of power equipment will generate heat due to friction during operation. Generally, cooling water is used as the cooling medium to remove the heat and realize the cooling of the equipment. For small equipment, the cooling water is generally passed directly into the cooling cavity inside the pump equipment to exchange heat directly with the equipment. For large-scale compressor equipment, lubricating oil stations are generally used. While lubricating the equipment with recycled lubricating oi...
