Generally speaking, most of the steam discharged by the equipment is discarded, that is, it is discharged from the production workshop after a simple post-processing process. The heat energy contained in the steam cannot be effectively utilized, resulting in energy waste. Utility Model Content

[0016] In some embodiments, the inlet end of the steam channel is provided with an inlet pipe, and the inlet pipe includes a first inlet pipe, a second inlet pipe and a junction pipe. The inlet end of the first inlet pipe is connected to the steam outlet of the distilled water machine, the inlet end of the second inlet pipe is connected to the steam outlet of the pure steam generator, the outlet end of the first inlet pipe and the outlet end of the second inlet pipe are both connected to the junction pipe, and the outlet end of the junction pipe is connected to the inlet end of the steam channel.

[0017] Compared with the prior art, the scheme shown in the embodiment of the present application is that the steam exhaust device is a device that requires the use of steam in the vaccine production process and will discharge waste steam and waste water (generally condensed water) during use.

It fully utilizes the thermal energy of the waste steam and the subsequent condensed water, and reuses them in the steam generating device, reducing the energy consumption of the steam supply of the vaccine production line, realizing energy reuse, saving production costs, and avoiding the adverse effects of steam emissions on the external environment.

[0030] Please also refer to Figure 1 and Figure 2 The vaccine industry waste steam recycling system provided by the present invention is now described. The vaccine industry waste steam recycling system comprises a steam exhaust device 1, a heat exchanger 2, a comprehensive tank 3, and a collection tank 4, which are sequentially connected. The heat exchanger 2 has a steam channel and a water channel. The steam channel has a steam inlet 201 at its inlet and a first water outlet 203 at its outlet. The water channel has an external water inlet 202 at its inlet and a second water outlet 204 at its outlet. The comprehensive tank 3 has a condensed water inlet 301 and a treated water inlet 302. The outlet of the steam exhaust device 1 is connected to the steam inlet 201, and the first water outlet 203 is connected to the condensed water inlet 301. The vaccine industry waste steam recycling system also includes a steam generating device 7, and a water storage tank 5 and a water treatment equipment 6 connected in sequence. The second water outlet 204 is connected to the water inlet of the water storage tank 5, and the water outlet of the water treatment equipment 6 is connected to the treated water inlet 302; the outlet of the steam generating device 7 is connected to the steam inlet 201, and the inlet of the steam generating device 7 is connected to the drain outlet of the collection tank 4.

[0031] In this embodiment, the steam discharge device 1 and the steam generating device 7 may share the same steam inlet 201 or may have separate steam inlets 201 ; the condensed water inlet 301 and the treated water inlet 302 may be the same inlet or may be separately provided.

[0032] In this embodiment, the external water source can be selected as a tap water source. The condensed water formed by the waste steam discharged by the steam exhaust device 1 and the steam generating device 7 is relatively pure. Based on this, the tap water needs to be pretreated by the water treatment equipment 6 to meet the water source conditions for the steam generating device 7 to generate steam. The pretreatment process mainly includes the following steps: first, filtering impurities such as mud / rust in the water; second, using cationic resin to adsorb calcium and magnesium ions in the water to achieve softening treatment; third, removing oxygen elements in the water to avoid corrosion of the pipeline. In the filtration step, the temperature of the tap water is appropriately increased through heat exchange between the tap water and the waste steam, that is, the water inlet temperature of the water treatment device is increased, which is beneficial to improving the water production efficiency of the water treatment device and ensuring the stability of the water supply to the integrated tank 3. More specifically, an insulation layer is provided in the water storage tank 5 to maintain the water temperature in the tank, avoid heat loss, and thus not affect the treatment effect of the water treatment equipment 6.

[0033] Compared with the prior art, the vaccine industry waste steam recycling system provided in this embodiment has a steam discharge device 1 that requires the use of steam in the vaccine production process and discharges waste steam and waste water (generally condensed water) during use. The steam generating device 7 is a device that actively generates steam. The steam generated by the steam generating device 7 serves as the steam source when the steam discharge device 1 is working. The steam generating device 7 also generates waste steam and waste water (generally condensed water) during operation. The waste steam and waste water discharged by the steam exhaust device 1 and the steam generating device 7 can enter the heat exchanger 2 through the steam inlet 201. The heat exchanger 2 is connected to the external water source through the external water inlet 202. When the steam circulates in the steam channel, the steam exchanges heat with the external water flowing in the water channel; after the heat exchange is completed, the waste steam condenses into condensed water, and the condensed water in the steam channel enters the integrated tank 3 through the first water outlet 203 and the condensed water inlet 301. At the same time, the heated external water enters the water storage tank 5 through the second water outlet 204; the water treatment equipment 6 treats the water in the water storage tank 5 to reduce impurities in the water, and the external water with improved water quality enters the integrated tank 3 through the external water inlet 202; after the condensed water and the external water with improved water quality are mixed in the integrated tank 3, they can return to the steam generating device 7 to continuously provide water for generating steam to meet the production needs of the vaccine production line. It can be seen that this embodiment uses waste steam and external water to perform heat exchange, so that the waste steam is liquefied to form condensed water. After the external water absorbs heat, its own temperature is increased, which is beneficial to improving the treatment efficiency of the water treatment device and reducing the heat required for the operation of the water treatment device. It fully utilizes the thermal energy of the waste steam and the subsequent condensed water, and reuses them in the steam generating device 7, reducing the energy consumption of the steam supply of the vaccine production line, realizing energy reuse, saving production costs, and avoiding the adverse effects of steam emissions on the external environment.

[0034] In some embodiments, see Figure 2 A buffer tank 8 is also provided between the steam discharge device 1 and the heat exchanger 2. The inlet of the buffer tank 8 is connected to the outlet of the steam discharge device 1, and the outlet of the buffer tank 8 is connected to the steam inlet 201. The buffer tank 8 can temporarily store the steam discharged from the steam discharge device 1, and then flow to the heat exchanger 2 after the steam accumulates to a certain amount. In this way, it is beneficial to continuously and stably supply steam to the heat exchanger 2, ensuring that the heat exchange process is stable and reliable. In addition, the steam discharge device 1 may include one device or multiple devices. In the case of including multiple devices, the buffer tank 8 can also mix and buffer multiple steam streams, making the steam flow to the heat exchanger 2 more stable, avoiding unstable steam pressure impacting the pipeline and the heat exchanger 2, and avoiding structural damage to the pipeline or the heat exchanger 2.

[0035] On the basis of the above embodiment, a heat-insulating layer is provided in the buffer tank 8 to maintain a high temperature state in the tank, to avoid rapid liquefaction and condensation of steam, and to avoid heat loss of steam.

[0036] In some specific embodiments, the outlet of the steam generating device 7 is connected to the buffer tank 8, and the waste steam and waste water discharged from the steam generating device 7 also enter the buffer tank 8, mix with the waste steam and waste water discharged from the steam exhaust device 1, and then enter the heat exchanger 2. Alternatively, Figure 1 The outlet of the steam generating device 7 is not connected to the buffer tank 8 and directly enters the heat exchanger 2.

[0037] In some embodiments, see Figure 2 The water storage tank 5 is also provided with a liquid level monitoring device to detect the amount of water in the water storage tank 5. If the amount of water is too much, it needs to be discharged in time to prevent external water from overflowing. Among them, the implementation of the liquid level monitoring device includes but is not limited to ultrasonic liquid level sensors, which are not listed here one by one.

[0038] On the basis of the installation of liquid level monitoring device, see Figure 2 A three-way control valve 9 is provided at the second water outlet 204. One outlet end of the three-way control valve 9 is connected to the water storage tank 5, and the other outlet end is connected to the water inlet of the integrated tank 3. The three-way control valve 9 is also connected to the liquid level monitoring device. Under normal working conditions, the three-way control valve 9 connects the second water outlet 204 and the water storage tank 5. If it is detected that the water quality in the integrated tank 3 does not meet the standards, the connection path with the water storage tank 5 is closed, and the connection path with the integrated tank 3 is opened, so that external water directly enters the integrated tank 3, and the water quality of the inlet water is adjusted until it meets the water quality requirements of the steam generating device 7. After the water quality is adjusted to the required level, the connection path with the integrated tank 3 is closed, and the connection path with the water storage tank 5 is reopened to restore the normal operating state.

[0039] In addition, if the water amount in the water storage tank 5 is detected to have reached a preset high value, the communication path with the water storage tank 5 is closed, and the communication path with the integrated tank 3 is opened, so that external water directly enters the integrated tank 3, and at the same time, the water in the water storage tank 5 is continuously transported to the water treatment device; after running in this way for a period of time, the liquid level in the water storage tank 5 returns to a safe low level, the communication path with the integrated tank 3 is closed, and the communication path with the water storage tank 5 is reopened, returning to normal operation to avoid waste of water resources.

[0040] Based on the above embodiments, see Figure 2 The water storage tank 5 also has a water replenishment port 501, which is connected to an external water source to directly replenish external water when the water level in the water storage tank 5 is too low, so as to avoid affecting the operation of the water treatment device.

[0041] In some embodiments, see Figure 2 The water treatment equipment 6 includes a purified water preparation device 610 and a softening device 620, which are connected in sequence. The water inlet of the purified water preparation device 610 is connected to the water outlet of the water storage tank 5, and the water outlet of the softening device 620 is connected to the treated water inlet 302. The water in the water storage tank 5 is first purified and filtered by the purified water preparation device 610, and then softened by the softening device 620. This high treatment efficiency and simple processing steps can meet the requirements of the subsequent use of the steam generation device 7. The purified water preparation device 610 can be implemented through methods such as reverse osmosis (RO) and resin ion exchange. Increasing the inlet water temperature can increase water production, thereby ensuring stable water production of the system. At the same time, the higher water temperature can also reduce the risk of pipe frost heave rupture.

[0042] In some embodiments, see Figure 2 The collection tank 4 has a first drain port 401 and a second drain port 402. The inlet of the steam generator 7 is connected to the first drain port 401, and the second drain port 402 is connected to the irrigation equipment. The water in the collection tank 4 can be used not only to generate steam but also for irrigation, thus fully utilizing the collected water and avoiding waste.

[0043] Based on the above embodiments, see Figure 2 To prevent low water levels in collection tank 4 from affecting the water supply to the tidying device or irrigation device, collection tank 4 is further provided with a water collection inlet 403, which is connected to an external water source. Collection tank 4 is also provided with an auxiliary monitoring device for liquid level monitoring, which may be implemented by, but not limited to, an ultrasonic level sensor.

[0044] In some embodiments, see Figure 2Based on the actual production needs of vaccine production, the steam exhaust device 1 includes a water distiller 110 and a pure steam generator 120. The water distiller 110 and the pure steam generator 120 are respectively connected to the steam inlet 201. The water distiller 110 and the pure steam generator 120 will both produce waste steam and waste water.

[0045] In some more specific embodiments, see Figure 2 In order to achieve the connection between the distilled water machine 110 and the pure steam generator 120 and the steam inlet 201, and at the same time improve the neat flow stability, an inlet pipe 10 is provided on the steam inlet side of the steam inlet 201. The inlet pipe 10 includes a first inlet pipe 1010, a second inlet pipe 1020 and a manifold 1030. The inlet end of the first inlet pipe 1010 is connected to the steam outlet of the distilled water machine 110, and the inlet end of the second inlet pipe 1020 is connected to the steam outlet of the pure steam generator 120. The outlet end of the first inlet pipe 1010 and the outlet end of the second inlet pipe 1020 are both connected to the manifold 1030, and the outlet end of the manifold 1030 is connected to the steam inlet 201.

[0046] For more details, see Figure 2 The water distiller 110 and the main steam generator are arranged along a path parallel to the long axis of the manifold 1030. The first inlet pipe 1010 and the second inlet pipe 1020 are both arranged at an angle to the manifold 1030. The first inlet pipe 1010 is connected to one end of the manifold 1030, and the second inlet pipe 1020 is connected to the middle of the manifold 1030. During operation, after the steam from the first inlet pipe 1010 enters the manifold 1030, it first flows for a distance to reduce its own flow rate before merging with the steam discharged from the second inlet pipe 1020. After the two streams merge, they flow again in the manifold 1030 for a period of time to mix, and finally the steam with a stable flow rate is delivered to the heat exchanger 2. This ensures that the steam in the heat exchanger 2 can fully exchange heat with the external water, improving heat exchange efficiency. At the same time, it also prevents the problem of unstable steam flow rate impacting the heat exchanger 2 and causing abnormal noise in the heat exchanger 2, thereby improving the operational stability of the heat exchanger 2.

[0047] Optionally, the manifold 1030 is provided with a plurality of guide plates 1031 spaced apart along the long axis of the manifold 1030. Adjacent guide plates 1031 are connected to opposite sides of the inner wall of the manifold 1030, thereby forming a tortuous flow path within the manifold 1030, as shown by the dotted line path in the figure. This can reduce the flow rate of the steam, extend the time the steam circulates within the manifold 1030, and enhance the uniformity of mixing of the two steam streams.

[0048] Optionally, the outer peripheries of the first inlet pipe 1010 , the second inlet pipe 1020 and the confluence pipe 1030 are all covered with a thermal insulation layer (eg, a thermal insulation cotton layer) to prevent the steam from condensing into water prematurely due to excessive heat loss during transportation.

[0049] In some embodiments, see Figure 2 The integrated tank 3 is equipped with a stirring device 11 to ensure thorough mixing of the condensed water and the external water. The stirring device 11 comprises a stirring driver 1110, a first extension shaft 1120, and a second extension shaft 1130. The stirring driver 1110 is located at the top of the integrated tank 3 and has an output shaft extending downward. The output shaft is coaxial with the integrated tank 3. The first extension shaft 1120 is connected to the output shaft of the stirring driver 1110 and the two are perpendicular to each other. The second extension shaft 1130 is connected to the other end of the first extension shaft 1120 and extends downward. The second extension shaft 1130 is equipped with a plurality of paddles 1140 arranged in a vertical direction. When the stirring driver 1110 outputs torque, the first extension shaft 1120 drives the second extension shaft 1130 to rotate about the output shaft. The second extension shaft 1130 and the paddles 1140 rotate together around the central axis of the integrated tank 3 to stir the liquid in the integrated tank 3 and achieve mixing. This arrangement does not require the provision of an overly long blade 1140 and can also achieve sufficient stirring of the water in the integrated tank 3. The overall structure of the stirring device 11 is simpler and lighter.

[0050] Optionally, a roller 1150 is provided at the lower end of the second extension shaft 1130 , and the roller 1150 rolls with the bottom wall of the integrated tank 3 to support the second extension shaft 1130 and the paddle 1140 and maintain the stability of the position of the second extension shaft 1130 .

[0051] In specific implementations, the steam generating device 7 may be implemented in ways that include, but are not limited to, an industrial steam generator. Furthermore, a first control valve 12 is provided on the discharge side of the steam discharge device 1 to control the on / off state of the first control valve 12 based on actual steam discharge requirements. A second control valve 13 is provided on the discharge side of the buffer tank 8 to control the opening of the second control valve 13 to discharge steam into the heat exchanger 2 after a certain amount of steam accumulates within the tank. The second control valve 13 can be closed when the amount of steam within the tank is low. The steam quantity is determined using an air pressure sensor. If the air pressure exceeds a preset high value, it is determined that there is sufficient steam to discharge into the heat exchanger 2. A third control valve 14 is provided at the external water inlet 202 of the heat exchanger 2 to control the on / off state and flow rate of the external water. A fourth control valve 15 is provided at the water replenishment port 501 of the water storage tank 5 to control the on / off state and flow rate of the external water. A fifth control valve 16 is provided on the outlet side of the water storage tank 5 to control the flow rate and on / off state of the water supply from the water storage tank 5 to the water treatment device. A sixth control valve 17 is installed between the purified water preparation unit 610 and the softening unit 620 to control the discharge flow of purified water. A seventh control valve 18 is installed at the outlet of the softening unit 620 to control the discharge flow of softened water. A water pump 19 is installed at the outlet of the integrated tank 3 to provide power for the water to flow to the collection tank 4. An eighth control valve 20 is installed at the water collection and replenishment port 403 of the collection tank 4. This eighth control valve 20 is connected to the auxiliary monitoring device to open the eighth control valve 20 for replenishment when the liquid level is detected to be too low. Ninth control valves 21 are installed at the first and second drain outlets 401 and 402, respectively, to control the water supply flow to the steam generator 7 and irrigation equipment.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
