Copious cooling liquid linkage filling system and filling method

Abstract

The invention provides a cryogenic liquid linkage filling system which comprises a storage tank, the storage tank is connected with a first weighing platform through a filling pipeline, a first branch filling pipeline is arranged on the filling pipeline, one end of the first branch filling pipeline is connected to the filling pipeline, and the other end of the first branch filling pipeline is connected to a gas-liquid separator; a second branch filling pipeline and a third branch filling pipeline are arranged on the first branch filling pipeline, one end of the second branch filling pipeline is connected to the second weighing platform, and one end of the third branch filling pipeline is connected to the third weighing platform; the other end of the third branch filling pipeline penetrates through the first branch filling pipeline and is connected to a safety valve, the filling device can automatically complete precooling and filling, the filling process is stable, efficient and safe, and the labor cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of cryogenic fluid equipment, in particular to a cryogenic liquid linkage filling system and filling method. Background technique [0002] With the continuous development of the national economy, the continuous improvement of the industrialization process, and the rapid development of industrial equipment, the market demand for cryogenic liquids continues to rise. At present, there are two main ways to obtain cryogenic liquids for equipment and containers that use cryogenic liquids: the first is to transport cryogenic liquids to equipment and containers through Dewar tanks. This solution requires frequent replacement of Dewar tanks. Safety risks such as joint air leakage often occur during the process, and it is not suitable for frequent entry and exit in the clean room. The second is to transport the cryogenic liquid to the equipment and container through the pipeline connecting the cryogenic storage tank....

At present, there are two main ways to obtain cryogenic liquids for equipment and containers that use cryogenic liquids: the first is to transport cryogenic liquids to equipment and containers through Dewar tanks. This solution requires frequent replacement of Dewar tanks. During the process, safety risks such as joint air leakage often occur, and it is not suitable for frequent entry and exit in the clean room

The second is to transport the cryogenic liquid to the equipment and container through the pipeline connecting the cryogenic storage tank. This solution can solve the problem of frequent replacement of the Dewar tank, but it cannot realize the automatic filling function.
