Abstract

The invention discloses a cooling water circulation device of a diesel engine. The cooling water circulation device comprises a cooling water pond and a circulation pipeline. A cooler and a variable frequency pump are arranged on the circulation pipeline. The circulation pipeline is composed of a water inlet pipeline and a water outlet pipeline. A water inlet three-way valve is arranged on the water inlet pipeline, and a water outlet three-way valve is arranged on the water outlet pipeline. The circulation device further comprises a pipeline wall thickness measuring meter and a descaling agentpond. The pipeline wall thickness measuring meter is arranged on the circulation pipeline. The descaling agent pond provides a descaling agent conveying pipeline to communicate with the water inlet three-way valve and provides a descaling agent backflow pipeline to communicate with the water outlet three-way valve. The circulation device further comprises a controller. According to the cooling water circulation device, the pipeline scaling condition can be monitored in real time, circulation of a descaling agent in the pipeline can be carried out automatically when too much scale is formed onthe inner wall of the pipeline, dirt in the pipeline is cleared away fast, normal cooling water circulation is automatically restored after the dirt is cleared away, the treatment time is short, theautomation degree is high, and an obvious promotion function is achieved on waste heat utilization of an ORC generator unit.

Description

technical field [0001] The invention relates to the technical field of marine diesel engines, in particular to a cooling water circulation device for diesel engines. Background technique [0002] my country's marine low-speed diesel engine waste heat utilization technology started late, and there is still a big gap with foreign ship main engine production companies and waste heat utilization system related companies in terms of key technology breakthroughs and supporting products. At present, energy conservation and emission reduction have become the wind vane of the development of the shipbuilding industry. How to reduce energy consumption, reduce emissions, and meet the EEDI requirements of IMO has always been one of the hot spots in the study of the shipbuilding industry. As the main power of the ship, the thermal efficiency of the diesel engine is close to 50%, but 50% of the energy is still taken away by the exhaust gas and cooling medium. If this part of waste heat ca...
