Problems solved by technology
[0004] There are some problems in the real-scale onshore test of PCHE for LNG: 1) The LNG working fluid required for the test process is flammable and explosive, and its storage has extremely strict environmental requirements. Safety issues are very important to be considered during the test process Therefore, there are almost no land-based laboratories that can use LNG as a working medium; 2) Some LNG storage tanks have a small storage capacity, which cannot meet the large demand for LNG in a large number of tests; A large amount of supercritical natural gas produced in the thermal process is difficult to recycle, and it is a waste to burn it. Liquefaction and recovery requires an additional set of natural gas liquefaction equipment, which is expensive, and direct discharge will pollute the environment and pose a safety hazard; 4) PCHE The heat exchange is large, and the demand for heating heat sources such as steam and propane is also large. The test also needs to increase the corresponding auxiliary devices, and the investment cost is huge.

The invention discloses an efficient and compact heat exchanger testing device and a testing method thereof. The efficient and compact heat exchanger testing device comprises a skid-mounted box body, as well as a heat source system, a cold source system, a measuring system and a monitoring system which are all arranged in the skid-mounted box body. The heat source system, the cold source system, the measuring system and the monitoring system are assembled in the skid-mounted box body and are integrated into a movable skid-mounted module, and four hose connecting interfaces connected with an FSRU are reserved on the skid-mounted module. When the heat exchange performance of a heat exchanger is tested, only the skid-mounted module needs to be connected with the FSRU, so that the field workload and the installation time are greatly saved, and the cost is saved.
Description
technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a high-efficiency compact heat exchanger testing device and a testing method thereof. Background technique [0002] With the increase in global natural gas demand and the development of the liquefied natural gas industry chain, the offshore LNG floating storage and regasification unit (FSRU) has gradually emerged and has become an important development direction in my country's energy field, and the heat exchanger is the core technology of the FSRU device part. As a new type of microchannel heat exchanger, the printed board heat exchanger (PCHE) has the characteristics of compactness, high efficiency, and reliability, and can meet the requirements of the main cryogenic heat exchanger for offshore floating liquefied natural gas (LNG) regasification. In recent years, it has gradually become one of the potential options for the main low-temperature heat exchanger of offshore fl...
