cooling system

Abstract

A cooling system comprises a refrigerant supply unit (10), a cooling unit (20) used for cooling a to-be-cooled object, a liquid seal groove (30) and a refrigerant recycling unit (40). The cooling unit (20) communicates with the refrigerant supply unit (10) through a refrigerant input pipe (21). The refrigerant recycling unit (40) comprises a refrigerant recycling pipe set (41) and a vacuum pump set (42). The refrigerant recycling pipe set (41) comprises a refrigerant recycling branch pipe (411), a vacuum pipe (412) and a siphon (413), all of which communicate with one another through the same port. The vacuum pump set (42) is connected with the vacuum pipe (412). The refrigerant recycling branch pipe (411) communicates with the cooling unit (20). The siphon (413) communicates with the liquid seal groove (30). The horizontal plane where the refrigerant supply unit (10) is located is higher than the horizontal plane where the liquid seal groove (30) is located. Due to the fact that a certain height difference exists between the refrigerant supply unit (10) and the liquid seal groove (30), cooling water in the refrigerant supply unit (10) can overcome resistance of a pipeline and enters the liquid seal groove (30) by itself. Due to the fact that the whole cooling system is in negative pressure, when the cooling unit is fractured, a refrigerant cannot overflow or hardly overflows, and accordingly production accidents caused by refrigerant overflow can be better reduced.

Description

Technical field [0001] The invention relates to the field of metallurgy, in particular to a cooling system. Background technique [0002] In the metallurgical process, it is necessary to cool the lining of the pyrometallurgical furnace to keep the temperature of the furnace lining at a lower temperature, which is beneficial to slow down the corrosion of the furnace body, so as to achieve the purpose of extending the life of the furnace body. Normally, the positive pressure cooling method is used for cooling. Positive pressure cooling means that the water pressure in the pipeline from the water inlet to the outlet of the cooling water system is always higher than one atmosphere. In this environment, the pressure and flow of the cooling water are adjusted to achieve the purpose of removing the surface heat of the cooled object in time. [0003] Positive pressure cooling has the characteristics of simple operation, easy adjustment of water pressure and water volume, and obvious cooli...
