[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] Please also read Figure 1 , the steam condensate heat recovery system for pharmaceutical factories provided by the utility model is now described. The steam condensate heat recovery system for pharmaceutical factories comprises a water storage tank 10, a transmission structure 20, an air conditioning device 30 and a matching controller. The water storage tank 10 has a hot water chamber 18 and a cold water chamber 19 for communicating with the steam condensate pipeline 50. The transmission structure 20 is arranged in the water storage tank 10, and is respectively connected to the hot water chamber 18 and the cold water chamber 19. The transmission structure 20 is used to introduce the water in the cold water chamber 19 into the hot water chamber 18 to adjust the water temperature in the hot water chamber 18. The air conditioning device 30 has a first heat medium channel, the inlet of the first heat medium channel is connected to the hot water chamber 18, and the outlet of the first heat medium channel is connected to the cold water chamber 19.

[0034] The steam condensate heat recovery system for pharmaceutical factories provided in this embodiment has a working principle that the steam condensate pipeline 50 is the outlet pipeline for condensation after being used in the pharmaceutical factory, and the water in the steam condensate pipeline 50 enters the hot water chamber 18, at which time the water temperature is usually between 80-90°C. The water temperature required by the heat medium channel of the air conditioning equipment 30 is between 60-65°C, so the transmission structure 20 can, under the control of the controller, introduce the cold water in the cold water chamber 19 into the hot water chamber 18 to adjust the water temperature in the hot water chamber 18 to between 60-65°C.

[0035] The water led out of the heat medium channel of the air conditioning device 30 enters the cold water chamber 19. The water temperature of this part of water is usually between 40-50° C., which is relative to the water temperature of the condensed water, and is used as cold water.

[0036] Compared with the prior art, the steam condensate heat recovery system for pharmaceutical plants provided in this embodiment can ensure the collection of condensate generated in pharmaceutical plants through the water storage tank 10, and adjust the temperature of condensate in the hot water chamber 18 to a temperature range suitable for the air conditioning equipment 30 through the transmission structure 20 inside the water storage tank 10, and then introduce it into the air conditioning equipment 30 for reuse. The system can be adapted to pharmaceutical plants without self-built boiler rooms, and has strong adaptability. At the same time, it can transmit the heat of condensate to the air conditioning equipment 30 for reuse, avoiding heat waste, and has strong practicality.

[0037] In some embodiments, the transmission structure 20 may be configured as follows: Figure 1 See the structure shown. Figure 1 The transmission structure 20 includes a transmission pipeline 21, a metering water pump 22 and a branch pipeline 23. One end of the transmission pipeline 21 extends into the bottom of the cold water chamber 19, and the other end extends into the hot water chamber 18. The metering water pump 22 is arranged on the transmission pipeline 21 and is electrically connected to the controller. There are at least two branch pipelines 23, and the two branch pipelines 23 are arranged in parallel. Each branch pipeline 23 is connected to the transmission pipeline 21 and is horizontally arranged in the hot water chamber 18. Each branch pipeline 23 is provided with a plurality of water outlets 24.

[0038] One end of the transmission pipeline 21 is located at the bottom of the cold water chamber 19, which can ensure that the extraction range of water in the cold water chamber 19 is increased, and the other end of the transmission pipeline 21 extends into the hot water chamber 18 and is connected to the branch pipeline 23. Through the operation of the metering water pump 22, the cold water can be introduced into the condensed water in the hot water chamber 18 through the water outlet 24 on the branch pipeline 23. This structure can ensure that the water temperature of the condensed water in the hot water chamber 18 is regulated, and the water outlets 24 can also promote the flow of water in the hot water chamber 18, thereby accelerating the mixing of condensed water and cold water to a certain extent, and improving the water temperature regulation rate. The structure is simple and practical.

[0039] It should be noted that the metering water pump 22 can control the amount of cold water entering the hot water chamber 18 according to the amount of condensed water entering the hot water chamber 18. Therefore, a flow meter can be set on the steam condensate water pipe. For example, the condensate entering the steam condensate water pipe is 100 liters, and the corresponding metering water pump 22 introduces 100 liters of cold water into the hot water chamber 18. The two need to be carried out at the same time. According to the heat balance equation, the final mixed water temperature can be calculated to be 65°C.

[0040] In some embodiments, the transmission structure 20 may be configured as follows: Figure 1 See the structure shown. Figure 1 Each water outlet 24 is vertically oriented upward because one end of the transmission pipeline 21 extends below the liquid surface of the condensed water in the hot water chamber 18, and the water outlet 24 is oriented upward. During the water outlet process, the condensed water in the hot water chamber 18 can be disturbed, thereby promoting the mixing of the condensed water and the cold water, achieving a certain stirring effect.

[0041] In some embodiments, the water storage tank 10 may be Figure 1 See the structure shown. Figure 1 The water storage tank 10 includes a box body 11 and a partition 12. The box body 11 has a receiving cavity. The partition 12 is arranged in the receiving cavity, and the partition 12 separates the receiving cavity into a hot water cavity 18 and a cold water cavity 19.

[0042] The accommodating chamber is separated by the partition 12, and the structure is simple and easy to manufacture. The partition 12 can be an insulating plate to avoid heat conduction between the cold water chamber 19 and the hot water chamber 18.

[0043] A notch may be provided at the top of the partition 12 to connect the hot water chamber 18 and the cold water chamber 19, and the corresponding transmission pipeline 21 may be U-shaped and pass through the notch.

[0044] Specifically, a hot water outlet 13 communicating with the hot water chamber 18 is provided at the bottom of the box body 11, and the hot water outlet 13 is communicated with the inlet of the first heat medium channel. This structure can prevent the water at the bottom of the hot water chamber 18 from being disturbed by the water at the water outlet 24, thereby ensuring constant temperature. A cold water inlet 14 communicating with the cold water chamber 19 is provided at the top of the box body 11, and the cold water inlet 14 is communicated with the outlet of the first heat medium channel.

[0045] An exhaust port may be provided at the top of the box body 11, and two hot water outlets 13 may be provided to ensure the regulation of the water output.

[0046] In some embodiments, the water storage tank 10 may be Figure 1 See the structure shown. Figure 1 The hot water chamber 18 and the cold water chamber 19 are both provided with temperature sensors, and each temperature sensor is electrically connected to the controller.

[0047] The temperature sensor can conveniently monitor the water temperature in the hot water chamber 18 and the cold water chamber 19 , so that the controller can control the amount of cold water entering through the metering water pump 22 , thereby facilitating the adjustment of the water temperature in the hot water chamber 18 .

[0048] In some embodiments, see Figure 1 The steam condensate heat recovery system for pharmaceutical factories also includes a shower heat exchange unit 40, which has a second heat medium channel, the inlet of the second heat medium channel is connected to the hot water chamber 18, and the outlet of the second heat medium channel is connected to the cold water chamber 19.

[0049] The addition of the shower heat exchange unit 40 can further ensure the reuse of condensed water and increase the reuse path. The shower heat exchange unit 40 can be understood as a heat exchanger, and the water flowing in its refrigerant channel is shower water. This technology is existing technology and will not be repeated here.

[0050] In some embodiments, the box 11 may be formed as follows: Figure 1 See the structure shown. Figure 1 A tap water inlet 15 connected to the cold water chamber 19 is provided at the top of the box body 11. The tap water inlet 15 can replenish the cold water in the cold water chamber 19, and can also ensure that the water temperature in the cold water chamber 19 is adjusted to ensure that the water temperature in the cold water chamber 19 is always lower than the water temperature in the hot water chamber 18.

[0051] In some embodiments, the box 11 may be formed as follows: Figure 1 See the structure shown. Figure 1 The top of the box body 11 is provided with a plurality of auxiliary water inlets 16 which are connected to the hot water chamber 18. The auxiliary water inlets 16 can ensure the addition of disinfection water, condensed water in the workshop and other drainage.

[0052] In some embodiments, the box 11 may be formed as follows: Figure 1 See the structure shown. Figure 1 The bottom of the box body 11 is provided with a drain port 17 connected to the cold water chamber 19, and the drain port 17 can ensure that the water in the cold water chamber 19 is discharged.
