cooling system

Abstract

A cooling system, comprising: a coolant supplying unit (10); a cooling unit (20) for cooling an object to be cooled, being connected to the coolant supplying unit (10) by means of a coolant inlet pipe (21); a coolant recovery unit (30), comprising a coolant recovery pipe network (31) and a coolant recovery tank (32), the coolant recovery pipe network (31) comprising a coolant recovery branch pipe (311) and a suction pipe (312) that are connected by means of the same port, the port of the coolant recovery branch pipe (311) that is away from the suction pipe (312) being connected to the cooling unit (20), the port of the suction pipe (312) that is away from the coolant recovery branch pipe (311) being connected to the coolant recovery tank (32), the horizontal plane of the coolant supplying unit (10) being higher than the horizontal plane of the coolant recovery tank (32); and a jet pump group (40), comprising an injector (41) and a jet pump (42), the injector (41) being connected to the jet pump (42), and the injector (41) being provided on and in connection with the suction pipe (312). The jet pump group is turned on to enable the fluid in the coolant recovery tank (32) to be discharged to the outside, such that the pressure in the coolant recovery tank (32) becomes negative, therefore coolant spillover will not, or will hardly, occur even if the cooling unit (20) has a leakage point, helping to reduce potential safety hazards and lower resistance to fluid flow.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a cooling system. Background technique [0002] During the metallurgical process, it is necessary to cool the lining of the high-temperature metallurgical furnace to keep the temperature of the furnace lining low, which is beneficial to slow down the corrosion of the furnace body, thereby achieving the purpose of prolonging the life of the furnace body. Normally, positive pressure cooling is used for cooling. Positive pressure cooling means that the water pressure in the pipeline of the cooling water system from the water inlet to the water outlet is always kept higher than one atmospheric pressure. In this environment, the pressure and flow of the cooling water are adjusted to remove the surface heat of the cooled object in time. [0003] Under normal circumstances, the circulating refrigerant enters the water jacket of the furnace body through the refrigerant input pipe, and returns ...
