Abstract

The invention provides a system for recycling vaporized cold quantities. The system can recycle the vaporized cold quantities of a cryogenic liquid with a higher energy utilization rate, and comprises an air-bath carburetor (3) connected with a cryogenic liquid tank (1), and a vaporized gas outlet of the cryogenic liquid (7). The system is characterized in that a water-bath carburetor (2) is connected in parallel at both ends of the air-bath carburetor (3), and a sink (4) of the water-bath carburetor (2) is connected with technological equipment (5) through a circulating water pump (6), a valve, a water supply pipeline (8) and a backwater pipeline (9) to form a cooling water circulating system.

Description

(1) Technical field [0001] The invention relates to system equipment for industrial energy recovery and utilization, in particular to a system for recovery and utilization of vaporized cooling capacity of cryogenic liquids. (2) Background technology [0002] At present, many domestic industrial plant process equipment need to use nitrogen, argon and other gases, and these gases are often vaporized from canned low-temperature liquid nitrogen, liquid argon, etc., especially in the electronics industry. The amount is also very large, and some plants use as much as 30 tons of liquid nitrogen per day. The low-temperature liquid nitrogen and argon will absorb heat during the vaporization process of the vaporizer, which will generate a large amount of cold around the vaporizer, thereby condensing the water vapor in the air around the vaporizer, resulting in a thick layer of frost on the vaporizer. If the above-mentioned large amount of cold energy is not recovered, it will not onl...
