The infusion tube 112 shown in fig. 1 has a disk-like structure, but the present embodiment is not limited to the disk-like structure, and the infusion tube 112 may have a U-shaped structure, an S-shaped structure, a spiral structure, or the like. When the infusion tube 112 has the above structure, the volume occupied by the infusion tube 112 is relatively small, and the contact area with the refrigerant is large, so that the heat exchange efficiency between the refrigerant and the liquid to be treated, that is, the refrigeration efficiency can be improved. In the implementation process, the liquid to be treated is input into the infusion tube 112 of the refrigeration device 110 through the input pump 113, the refrigerant is contained in the cavity 111, the refrigerant exchanges heat with the liquid to be treated in the infusion tube 112 for refrigeration, and then the refrigerated liquid is input into the first storage tank 120 for storage.
Referring to fig. 2, the refrigeration device 110 further includes a refrigerant regulating valve 114 connected to the refrigerant regulating valve 114; the cavity 111 is connected with a refrigerant storage tank storing refrigerant through a refrigerant regulating valve 114; and a refrigerant regulating valve 114 for regulating the refrigerant in the cavity 111, wherein the refrigerant regulating valve 114 can be regulated according to the target temperature, and the cavity 111 is connected with the refrigerant storage tank through the refrigerant regulating valve 114. The refrigerant input into the cavity 111 from the refrigerant storage tank can be adjusted by the refrigerant adjusting valve 114, so that the adjustment of the refrigeration power is realized.
Use the refrigerant to be the liquid nitrogen as the example, the liquid nitrogen can be sprayed in transfer line 112 through the shower nozzle, improves the utilization ratio of liquid nitrogen, in addition, can also be through a plurality of refrigerant governing valves 114 with the even input of liquid nitrogen to refrigerating plant 110's cavity 111 in, liquid nitrogen and pending liquid carry out the heat exchange after, the liquid nitrogen vaporization is nitrogen gas, discharges through the gas vent that cavity 111 set up.

For example, the pressure value at the inlet of the liquid transport tube 112 is detected, and when the pressure value at the inlet is smaller than a preset value, that is, when the liquid transport tube 112 is not clogged, the refrigerant around the liquid transport tube 112 can be adjusted according to the target temperature. If the pressure value at the inlet is not less than the preset value, the refrigeration device 110 may stop the refrigeration operation, specifically, the refrigerant regulating valve 114 may be adjusted to stop feeding the refrigerant into the cavity 111, or the input pump 113 may be controlled to stop inputting the liquid to be treated into the liquid conveying pipe 112, so as to reduce the pressure borne by the liquid conveying pipe 112, thereby preventing the refrigeration device 110 from being damaged due to blockage.
