As can be seen from above, the crystallizing tank refrigerating plant that the utility model provides by the installation of refrigerant transfer tank, was lowered the temperature before refrigerant flows back to storage tank, made the refrigerant in storage tank keep cold, had guaranteed refrigeration.The setting of the second circulating line makes to flow out a part of refrigerant after crystallizing tank and can again be incorporated to into matchmaker and roll into a ball with fresh refrigerant and together proceed refrigeration, takes full advantage of refrigerant, has further reduced energy consumption.
Accompanying drawing explanation
Fig. 1 is the utility model crystallizing tank refrigerating plant embodiment schematic diagram;
Fig. 2 is the utility model crystallizing tank refrigerating plant the first circulating line embodiment schematic diagram.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the utility model is further described.
Crystallizing tank refrigerating plant as shown in Figure 1, is loaded with grease to be cooled in crystallizing tank 1, cooling coil is the refrigerating plant in crystallizing tank 1, is divided into upper and lower two parts coil pipe, and every a part of coil pipe has respectively an entrance and exit.The entrance and exit of upper part cooling coil is called upper inlet 7 and upper outlet 8, and the entrance and exit of lower part cooling coil is called lower inlet 9 and lower outlet 10.The upper inlet 7 of crystallizing tank 1 is connected by pipeline with storage tank 2 with lower inlet 9, and this segment pipe is called into matchmaker's pipeline 5, and fresh refrigerant is through entering matchmaker's pipeline 5 and pumped into upper inlet 7 by pump 12 and lower inlet 9 entering cooling coil.Refrigerant is flowed through after cooling coil lowers the temperature to the grease in crystallizing tank 1, flows out respectively from upper outlet 8 and outlet 10.Upper outlet 8 is connected with the first circulating line 6 with lower outlet 10, and the other end of the first circulating line 6 connects respectively storage tank 2 and transfer tank 3, and transfer tank 3 is connected with storage tank 2 by refrigeration machine 4.Refrigerant flows back to storage tank 2 or transfer tank 3 through the first circulating line 6, can be by the valve control on pipeline.Significantly raise if flow out the temperature of refrigerant of crystallizing tank 1, directly flow back to the cold that storage tank 2 can the serious refrigerant that lowers storage, can select to allow refrigerant first flow to transfer tank 3, entering refrigeration machine 4 after naturally cooling freezes, and finally flows back in storage tank 2.
By the installation of refrigerant transfer tank 3, before flowing back to storage tank 2, refrigerant lowers the temperature, and make the refrigerant in storage tank 2 keep cold, guarantee refrigeration, reduce the energy consumption of refrigeration machine 4.
As one preferred embodiment, as shown in Figure 2, the upper outlet 8 of crystallizing tank and lower outlet 10 also by pipeline with enter matchmaker's pipeline 5 and be connected, this section of connecting pipe is called the second circulating line 11.The refrigerant flowing out from upper outlet 8 and outlet 10 can enter into matchmaker's pipeline 5 again through the second circulating line 11, is pumped to crystallizing tank 1 and freezes together with fresh refrigerant, has improved the utilization rate of refrigerant.At work, as shown in Figure 2, together with the refrigerant flowing out converges to, require refrigerant to be divided into two-way according to concrete cooling from upper outlet 8 with outlet 10, wherein a road refrigerant first circulating line 6 of flowing through enters transfer tank 3, finally flows back to storage tank 2; Another road refrigerant enters into matchmaker's pipeline 5 again through the second circulating line 11, is pumped in crystallizing tank 1 and again grease is lowered the temperature together with fresh refrigerant.The utilization of this shunting design maximizes refrigerant, reduced energy consumption for cooling.
As one preferred embodiment, as shown in Figure 2, on described the first circulating line 6, pneumatic operated valve 13 and temperature control system are installed, the switch of described pneumatic operated valve 13 and the size of folding are subject to temperature control system control, described in described temperature control system control pneumatic operated valve 13 adjust refrigerant flow back to the ratio of described transfer tank 3 and again flow into described in enter the ratio of matchmaker's pipeline 5, reasonably alleviate the load of refrigeration machine 4, reduce energy consumption.Described temperature control system adopts conventional PLC system (Programmable Logic Controller) now to control, and it is not only temperature control system.Its main operation logic is: by being arranged on the equipment such as temperature sensor, pressure sensor and the liquid level monitoring in workshop, real time information is fed back to PLC system, system is according to the technological requirement of setting, assign instruction to equipment such as valves, control its opening degree, so that it reaches technological requirement.As, cold is carried for making full use of refrigerant in workshop, system can first-selected allow refrigerant after heat exchange through the oil supply cooling that refluxes again of the second circulating line 11, but winterization crystallization growing the grain process has strict demand to cooling rate, in the time that TEMP feeds back to PLC system information and shows that refrigerant cold can not meet the demand of cooling rate in cooling coil, PLC system can be assigned rapidly instruction, open or increase the opening degree of pneumatic operated valve 13, increase and be back to coolant quantity after the heat exchange of transfer tank 3, reduce and enter coolant quantity after the second circulating line 11 heat exchange, increase simultaneously and control fresh refrigerant input valve opening degree, thereby the fresh refrigerant ratio that enters cooling coil increases, cooling rate is accelerated, in the time finding that cooling rate is too fast, situation is contrary.
Optionally, described in enter matchmaker's pipeline 5 and be connected by emptying pipe 14 with described storage tank 2, in the time of work, emptying pipe 14 is closed, and after crystallizing tank 1 has freezed, opens emptying pipe 14, drains in storage tank 2 remaining in into the refrigerant of matchmaker's pipeline 5.
As can be seen from above, the crystallizing tank refrigerating plant that the utility model provides by the installation of refrigerant transfer tank 3, was lowered the temperature before refrigerant flows back to storage tank 2, made the refrigerant in storage tank 2 keep cold, had guaranteed refrigeration.The setting of the second circulating line 11 makes a part of refrigerant after refrigeration can be directly incorporated into fresh refrigerant and proceeds refrigeration, takes full advantage of refrigerant, has further reduced energy consumption.
Those of ordinary skill in the field are to be understood that: the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle; any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
