Problems solved by technology

[0004] When the traditional cryogenic treatment equipment operates at cryogenic temperature, in order to overcome the heat exchange between the equipment and the environment space, liquid nitrogen needs to be continuously replenished. At the same time, in order to ensure the balance of the quality and energy of the system, a part of the low-temperature nitrogen needs to be discharged from the outlet. The cooling capacity of this part of the nitrogen will be wasted as the nitrogen is released into the atmosphere

Abstract

The invention discloses a cryogenic treatment device with a cold energy recovering device. The cryogenic treatment device with the cold energy recovering device comprises a cryogenic device box body (1) and a liquid nitrogen supply device (2), and is characterized by further comprising the cold energy recovering device (3) which is connected with a nitrogen outlet of the cryogenic device box body (1) and is used for recovering cold energy in nitrogen discharged from the nitrogen outlet. Due to the fact that the old energy recovering device which is used for recovering the cold energy in the nitrogen discharged by the cryogenic treatment device is arranged at the position of a nitrogen outlet of a traditional cryogenic treatment device, the mode that the cold energy is directly discharged by the traditional cryogenic treatment device is changed. The cryogenic treatment device with the cold energy recovering device can reduce consumption of liquid nitrogen, and therefore energy consumption of the device is reduced. Besides, the cryogenic treatment device with the cold energy recovering device further has the advantages of being high in recovering efficiency and in operation stability, easy to control and the like.

Description

technical field [0001] The invention relates to the technical field of cryogenic treatment, in particular to a cryogenic treatment equipment with a cold recovery device. Background technique [0002] Cryogenic treatment is a supplementary process of ordinary heat treatment, which can effectively improve the mechanical properties of materials such as wear resistance, dimensional stability, strength and toughness, thereby improving product quality, prolonging service life, and ultimately reducing production costs. In recent years, some large and small domestic enterprises have added the cryogenic treatment process to their production lines. At the same time, the liquid nitrogen used in the cryogenic treatment process is easier to obtain and the cost of liquid nitrogen is reduced, which also promotes the wide application of cryogenic treatment technology. [0003] Cryogenic treatment equipment is a kind of equipment that can heat up and down temperature and heat preservation of...
