Nuclear power station diesel oil system pipeline low-temperature environment oil cleaning system and process thereof

Abstract

The invention belongs to the technical field of nuclear power station pipeline engineering construction, and particularly discloses a diesel system pipeline low-temperature environment oil cleaning system and a process thereof. The diesel system pipeline low-temperature environment oil cleaning system comprises a primary loop system and a secondary loop system, and the primary loop system comprises a water tank, a stop valve A, a water pump, a check valve A, a regulating valve B, a heat exchanger and a stop valve C which are sequentially connected in series; and the secondary loop system comprises a heat exchanger, a stop valve D, an oil pump, a check valve B, an adjusting valve E, a stop valve F, a filter screen, a stop valve G, a sampling valve A and a sampling valve B, wherein the stop valve D, the oil pump, the check valve B and the adjusting valve E are sequentially connected with the heat exchanger in series, and the stop valve F, the filter screen, the stop valve G, the sampling valve A and the sampling valve B are sequentially connected with the heat exchanger in series. The primary loop system exchanges heat with the secondary loop system through the heat exchanger. According to the diesel system pipeline low-temperature environment oil cleaning system and the process thereof, when the atmospheric environment temperature is lower than or reduced to the diesel oil condensation point temperature (0 DEG C) in the oil cleaning process of the diesel oil system pipeline, the wax precipitation phenomenon of diesel oil is avoided; and meanwhile, the oil cleaning efficiency of the diesel oil system pipeline is improved, the oil cleaning time is shortened, and the labor cost is saved.

Description

Technical field [0001] The present invention belongs to the construction technology of nuclear power plant pipeline engineering, and in particular, the present invention relates to a low temperature environmental oil cleaning system of diesel system pipelines and processes. Background technique [0002] Engineering experience shows that the quality of diesel system pipeline oil cleaning directly affects the normal operation of diesel engine equipment, and the pipeline cleanliness will result in a decrease in filter efficiency, and impurities enters an abnormal grinding problem inside the diesel engine, resulting in wear of diesel engine parts, resulting in diesel engine The life and reliability have declined. [0003] According to the "Industrial Metal Pipeline Engineering Construction Specification" GB 50235-2010, the oil pipeline of the lubrication, seal and control system should be cleaned before the mechanical equipment and the pipeline is cleaned, and the system will be clea...
