[0002] When conducting biopharmaceutical production, it is usually necessary to inactivate the live viral wastewater during the wastewater discharge process. Inactivation treatment refers to the use of physical or chemical methods to destroy the higher-order structure of the viral protein in the wastewater, so that the viral protein no longer has physiological activity and thus loses its ability to infect, cause disease and reproduce.

[0003] In traditional technology, high-temperature heating is usually used to inactivate viral proteins in waste liquid. However, this method consumes a lot of energy, which in turn increases the cost of inactivation treatment. Summary of the invention

[0030] See also Figure 1 An embodiment of the present application provides a waste liquid treatment device, including a first pipeline 100, a second pipeline 200, a preheating module 300, a heating module 400 and a heat absorption module 500, the heating module 400 has a connected heating chamber 410, a first inlet 420 and a first outlet 430, one end of the first pipeline 100 is used for entering the waste liquid, the other end of the first pipeline 100 is connected to the first inlet 420, one end of the second pipeline 200 is connected to the first outlet 430, and the other end of the second pipeline 200 is used to discharge the waste liquid after heating treatment, the preheating module 300 is arranged in the first pipeline 100, and the heat absorption module 500 is arranged in the second pipeline 200, and the heat absorption module 500 can transfer heat to the preheating module 300.

[0031] In the above-mentioned waste liquid treatment equipment, the waste liquid that has not been inactivated can enter the heating chamber 410 from the first pipeline 100 through the first inlet 420, and the heating module heats the waste liquid in the heating chamber 410 to inactivate the waste liquid. The heated high-temperature waste liquid enters the second pipeline 200 from the first outlet 430 to discharge the waste liquid. In this process, the heat absorption module 500 can absorb the heat of the high-temperature waste liquid in the second pipeline 200 and transfer the heat to the preheating module 300 arranged on the first pipeline 100, so that the preheating module Block 300 preheats the unheated waste liquid in the first pipeline 100, and the preheated waste liquid enters the heating chamber 410 of the heating module 400 from the first inlet 420. Since the temperature of the preheated waste liquid is higher than that of the waste liquid at room temperature, the heating module 400 consumes less energy to heat the waste liquid to the inactivation temperature and thus inactivates the waste liquid. Compared with traditional technologies, the above-mentioned waste liquid treatment equipment consumes less energy when inactivating the waste liquid, thereby reducing the cost of waste liquid inactivation treatment.

[0032] Optionally, see Figure 1 In some embodiments, one end of the first pipeline 100 can be directly connected to the waste liquid discharge pipeline of the pharmaceutical system, or it can be connected to the waste liquid storage tank, which is not specifically limited here; accordingly, one end of the second pipeline 200 can be directly connected to the waste liquid discharge pipeline, or it can be connected to other types of waste liquid treatment equipment such as a filtering equipment to further treat the waste liquid, which is not specifically limited here.

[0033] See also Figure 1 In some embodiments, a pipeline pump 110 is provided on the first pipeline 100, and the pipeline pump 110 can increase the pressure of the waste liquid in the first pipeline 100 to ensure the flow rate of the waste liquid and prevent the fungus residue in the waste liquid from solidifying and depositing in the waste liquid treatment equipment and affecting the flow continuity of the waste liquid.

[0034] See also Figure 1 In one embodiment, the waste liquid treatment equipment also includes a heat medium storage module 600, which has a connected heat medium cavity, a second outlet 610 and a second inlet 620. The heat medium cavity is used to store heat medium. The second outlet 610 is connected to the heat absorption module 500, the heat absorption module 500 is connected to the preheating module 300, and the preheating module 300 is connected to the second inlet 620.

[0035] The heat medium cavity of the heat medium storage module 600 is used to store heat medium, and the heat medium enters the heat absorption module 500 through the second outlet 610. The heat medium in the heat absorption module 500 can absorb the heat of the high-temperature waste liquid in the second pipeline 200. The high-temperature heat medium after absorbing heat enters the preheating module 300. The high-temperature heat medium in the preheating module 300 can transfer heat to the unheated waste liquid in the first pipeline 100 to preheat the unheated waste liquid in the first pipeline 100. The heat medium after releasing heat flows back to the heat medium cavity through the second inlet 620, and then enters the heat absorption module 500 from the second outlet 610, and so on. By preheating in this way, the unheated waste liquid can be preheated continuously and uninterruptedly without consuming additional energy, so that the heating module 400 can consume less energy to heat the waste liquid to the inactivation temperature and thus inactivate the waste liquid.

[0036] In addition, the heat medium in the heat absorption module 500 absorbs heat from the high-temperature waste liquid in the second pipeline 200 to cool the high-temperature waste liquid, and the temperature of the waste liquid in the second pipeline 200 can also be reduced to the emission standard.

[0037] For example, in some embodiments, the heat medium may be a flowing liquid, such as oil, water, etc., which is not specifically limited here.

[0038] See also Figure 1 In some embodiments, a first liquid outlet valve 630 and a circulation pump 640 are provided near the second outlet 610 of the heat medium storage module 600. The first liquid outlet valve 630 can control the flow rate of the heat medium at the second outlet 610, and the circulation pump 640 can increase the pressure of the heat medium to ensure that the heat medium can flow between the heat absorption module 500, the preheating module 300 and the heat medium cavity.

[0039] See also Figures 1 to 3 In one embodiment, the heat absorption module 500 includes a heat absorption sleeve 510, which is sleeved on the second pipeline 200, and the inner wall of the heat absorption sleeve 510 is spaced from the outer wall of the second pipeline 200 to form a heat absorption cavity, and the heat absorption cavity is connected to the second outlet 610. The preheating module 300 includes a preheating sleeve 310, which is sleeved on the first pipeline 100, and the inner wall of the preheating sleeve 310 is spaced from the outer wall of the first pipeline 100 to form a preheating cavity, and the preheating cavity is connected to the heat absorption cavity and the second inlet 620.

[0040] The heat absorption chamber is connected to the second outlet 610, so that the heat medium absorbs heat from the high-temperature waste liquid in the second pipeline 200 in the heat absorption chamber to form a high-temperature heat medium. The high-temperature heat medium in the heat absorption chamber enters the preheating chamber to exchange heat with the waste liquid in the first pipeline 100, thereby preheating the unheated waste liquid. After the preheating is completed, the temperature of the heat medium in the preheating chamber decreases and returns from the second inlet 620 to the heat medium chamber of the heat medium storage module, and so on. The heat absorption chamber is formed between the heat absorption sleeve 510 sleeved on the outer wall of the second pipeline 200 and the second pipeline 200, and the preheating chamber is formed between the preheating sleeve 310 sleeved on the outer wall of the first pipeline 100 and the first pipeline 100 to exchange heat between the heat medium and the waste liquid. The structure is compact and the heat exchange effect is good. The heat loss generated during the heat exchange is small and the heat exchange efficiency is high.

[0041] See also Figures 2 to 3 In some embodiments, at least two heat absorbing sleeves 510 are provided and arranged in parallel with each other, the heat absorbing chambers are interconnected, and the second pipeline 200 is coiled and penetrated through at least two heat absorbing sleeves 510; at least two preheating sleeves 310 are provided and arranged in parallel with each other, the preheating chambers are interconnected, and the first pipeline 100 is coiled and penetrated through at least two heat absorbing sleeves 510; such an arrangement can enhance the heat exchange effect between the heat medium and the waste liquid and improve the heat exchange efficiency.

[0042] In one embodiment, a steam delivery module is disposed in the heating chamber 410 , and the steam delivery module is used to deliver steam into the heating chamber 410 .

[0043] The waste liquid preheated by the preheating module 300 enters the heating chamber 410 through the first inlet 420, and the steam delivery module delivers steam to the heating chamber 410. The steam and the waste liquid in the heating chamber 410 are fully in contact and heat exchanged to heat the waste liquid. During the mixing process, the steam and the waste liquid will flow at a high speed in the heating chamber 410 to prevent the solidification and deposition of bacterial residues or proteins in the waste liquid from causing blockage, thereby improving the efficiency of waste liquid treatment.

[0044] For explanation, the inactivation temperature of the waste liquid is usually above 139°C, therefore, the steam delivery module delivers steam into the heating chamber 410, and the steam is in sufficient contact and heat exchange with the waste liquid in the heating chamber 410 to heat the waste liquid to above 139°C, thereby achieving the inactivation effect on the waste liquid.

[0045] See also Figure 4 In one embodiment, the steam delivery module has a steam input port 441 and a steam output port 442 that are connected, the steam input port 441 is used to communicate with the steam generation module, and the steam output port 442 is connected with the heating chamber 410.

[0046] The steam generated by the steam generation module can enter the steam delivery module through the steam input port 441 and enter the heating chamber 410 through the steam output port 442 to fully contact and exchange heat with the waste liquid, thereby achieving an inactivation effect; such a setting has a simple structure and low manufacturing cost.

[0047] See also Figure 4 In one embodiment, the steam delivery module includes a steam delivery pipe 440, a steam input port 441 is arranged at one end of the steam delivery pipe 440, a steam output port 442 is arranged on the side wall of the steam delivery pipe 440 and at least two steam output ports 442 are arranged at intervals along the axial direction of the steam delivery pipe 440.

[0048] The steam generated by the steam generating module enters the steam delivery pipe 440 through the steam input port 441 at one end of the steam delivery pipe 440, and then enters the heating chamber 410 through at least two steam output ports 442 spaced apart along the axial direction of the steam delivery pipe 440 to exchange heat with the waste liquid; the at least two steam output ports 442 can output steam to the heating chamber 410 more evenly, so that the steam and the waste liquid in the heating chamber 410 can be in more sufficient contact and heat exchange, thereby improving the heat exchange efficiency.

[0049] Furthermore, a steam input port 441 at one end of the steam delivery pipe 440 extends out of the heating chamber 410 so as to be connected to the steam generating module.

[0050] In some embodiments, the steam delivery pipe 440 is connected to the steam generation module through a temperature regulating valve 443, and the temperature regulating valve 443 can adjust the amount of steam entering the steam delivery pipe 440 from the steam generation module, thereby adjusting the heating temperature of the waste liquid; specifically, when the heating temperature needs to be increased, the amount of steam entering the steam delivery pipe 440 needs to be increased through the temperature regulating valve 443, and correspondingly, when the heating temperature needs to be lowered, the amount of steam entering the steam delivery pipe 440 needs to be reduced through the temperature regulating valve 443.

[0051] Specifically, the temperature regulating valve 443 is disposed on a pipeline for connecting the steam delivery pipe 440 and the steam generation module.

[0052] See also Figure 1In one embodiment, the waste liquid treatment equipment further includes a waste liquid storage module 700, a temperature monitoring module 800 and a discharge valve 211. The waste liquid storage module 700 is provided with a connected liquid storage chamber, a liquid return port 710 and a third outlet 720. The end of the second pipeline 200 away from the first outlet 430 is provided with a first branch 210 and a second branch 220. The first branch 210 is used to communicate with the wastewater discharge module, the second branch 220 is connected to the liquid return port 710, and the third outlet 720 is connected to the end of the first pipeline 100 away from the first inlet 420. The temperature monitoring module 800 is provided in the second pipeline 200 and is used to monitor the temperature of the waste liquid in the second pipeline 200. The discharge valve 211 is provided in the first branch 210 and is used to control the flow of the first branch 210. The discharge valve 211 is electrically connected to the temperature monitoring module 800.

[0053] The temperature monitoring module 800 is electrically connected to the discharge valve 211. When the temperature monitoring module 800 detects that the temperature of the waste liquid in the second pipeline 200 has not reached the preset temperature, it indicates that the inactivation of the waste liquid in the second pipeline 200 has failed. The temperature monitoring module 800 sends an electrical signal to the discharge valve 211 to make the discharge valve 211 close the first branch 210. At this time, the waste liquid that has failed to be inactivated in the second pipeline 200 can only flow to the second branch 220, and flow from the second branch 220 to the return liquid port 710 to enter the liquid storage chamber of the waste liquid storage module 700, and the waste liquid in the liquid storage chamber enters the first pipeline 100 again through the third outlet 720 for a new round of inactivation treatment. Such a setting can ensure the inactivation effect of the waste liquid and prevent the incompletely inactivated waste liquid from being discharged to the outside.

[0054] Furthermore, in some embodiments, since the inactivation temperature of the waste liquid is usually above 139°C, the heating module 400 needs to heat the waste liquid to above 139°C to ensure the inactivation effect of the waste liquid. When the waste liquid heated by the heating module 400 flows to the second pipeline 200, some heat loss has been generated in the process. Therefore, the preset temperature to be monitored by the temperature monitoring module 800 is usually set to 135°C. That is, when the temperature monitoring module 800 detects that the temperature of the waste liquid in the second pipeline 200 is less than 135°C, it indicates that the heating module 400 has not heated the waste liquid to 139°C, which further indicates that the inactivation has failed. At this time, the temperature monitoring module 800 sends an electrical signal to the discharge valve 211 to close the discharge valve 211. The first branch 210 is closed, and the waste liquid that has failed to be inactivated in the second pipeline 200 can only flow to the second branch 220, and flow from the second branch 220 to the liquid return port 710 to enter the liquid storage chamber of the waste liquid storage module 700. The waste liquid that has failed to be extinguished will re-enter the first pipeline 100 through the third outlet 720 along with the waste liquid in the liquid storage chamber for a new round of inactivation treatment; when the temperature monitoring module 800 detects that the temperature of the waste liquid in the second pipeline 200 is greater than 135°C, it indicates that the heating module 400 heats the waste liquid to above 139°C, which further indicates that the inactivation is successful. At this time, the temperature monitoring module 800 sends an electrical signal to the discharge valve 211 to enable the discharge valve 211 to open the first branch 210, thereby discharging the successfully inactivated waste liquid.

[0055] See also Figure 1 In some embodiments, the waste liquid storage module 700 is also provided with a third inlet 730 connected to the liquid storage chamber. The third inlet 730 is connected to the waste liquid discharge pipeline. The waste liquid discharge pipeline can introduce the waste liquid produced by the pharmaceutical system into the liquid storage chamber of the waste liquid storage module 700 through the third inlet 730.

[0056] See also Figure 1 In some embodiments, a second liquid outlet valve 120 is provided in the first pipeline 100 near the third outlet 720. The second liquid outlet valve 120 can control the flow rate of the waste liquid in the first pipeline 100 so that the flow rate of the waste liquid in the first pipeline 100 is always within a preset flow rate range.

[0057] See also Figure 1 In some embodiments, a pressure regulating assembly 230 is further provided in the second pipeline 200 near the discharge valve 211. The pressure regulating assembly 230 includes a pressure sensor and a pressure regulating valve. The pressure sensor can monitor the back pressure at the front end of the discharge valve 211. The pressure regulating valve is electrically connected to the pressure sensor. The pressure regulating valve can adjust the pressure of the waste liquid during flow to ensure that the back pressure at the front end of the discharge valve 211 can be maintained above the set value of the pressure sensor, thereby ensuring that the pressure in the waste liquid treatment equipment is higher than the saturated steam pressure corresponding to the preset temperature of the temperature monitoring module 800.

[0058] By way of explanation, in the above embodiment, if the pressure inside the waste liquid treatment equipment is lower than the saturated steam pressure corresponding to the preset temperature of the temperature monitoring module 800, the liquid in the waste liquid treatment equipment will vaporize, the gas will be compressed, and the pressure inside the waste liquid treatment equipment will increase sharply, thereby making it impossible for the waste liquid to flow continuously, affecting the waste liquid treatment effect.

[0059] See also Figure 1 In one embodiment, the waste liquid treatment equipment further includes a reflux valve 221 , which is disposed in the second branch 220 and is used to control the flow of the second branch 220 , and the reflux valve 221 is electrically connected to the temperature monitoring module 800 .

[0060] The temperature monitoring module 800 is electrically connected to the reflux valve 221. When the temperature monitoring module 800 detects that the temperature of the waste liquid in the second pipeline 200 does not reach the preset temperature, it indicates that the waste liquid in the second pipeline 200 has failed to be inactivated. The temperature monitoring module 800 simultaneously sends an electrical signal to the reflux valve 221 and the discharge valve 211, so that the reflux valve 221 opens the second branch 220 and the discharge valve 211 closes the first branch 210. At this time, the waste liquid that has failed to be inactivated in the second pipeline 200 can only flow to the second branch 220, and flow from the second branch 220 to the liquid return port 710 to enter the liquid storage cavity of the waste liquid storage module 700. The waste liquid that failed to extinguish the fire will enter the first pipeline 100 again through the third outlet 720 along with the waste liquid in the liquid storage chamber for a new round of inactivation treatment; accordingly, when the temperature monitoring module 800 detects that the temperature of the waste liquid in the second pipeline 200 reaches the preset temperature, it indicates that the waste liquid in the second pipeline 200 is successfully inactivated, and the temperature monitoring module 800 simultaneously sends an electrical signal to the reflux valve 221 and the discharge valve 211, so that the reflux valve 221 closes the second branch 220, and the discharge valve 211 opens the first branch 210. At this time, the waste liquid that successfully extinguished the fire in the second pipeline 200 can only flow to the first branch 210 and be discharged. By respectively setting the discharge valve 211 and the reflux valve 221 on the first branch 210 and the second branch 220, the inactivation effect and inactivation accuracy of the waste liquid can be further guaranteed, and the inactivated waste liquid can be prevented from being discharged to the outside and causing pollution.

[0061] See also Figure 1 In one embodiment, the waste liquid treatment equipment further includes a coiled insulation pipeline 900 , one end of the insulation pipeline 900 is connected to the first outlet 430 , and the other end of the insulation pipeline 900 is connected to the second pipeline 200 .

[0062] After being heated, the waste liquid in the heating chamber 410 enters the insulation pipeline 900 from the first outlet 430. The insulation pipeline 900 can insulate the high-temperature waste liquid after heating, thereby ensuring that the waste liquid is completely inactivated and enhancing the inactivation effect. The insulation pipeline 900 is coiled, which can not only improve the space utilization rate to a certain extent, but also reduce the heat loss of the high-temperature waste liquid in the insulation pipeline 900, further enhancing the inactivation effect.

[0063] By way of explanation, by providing the insulation pipeline 900, the waste liquid can be kept insulated and flowed in the insulation pipeline 900 after reaching the inactivation temperature, thereby ensuring that the waste liquid is completely inactivated; specifically, it is usually necessary to keep the waste liquid insulated and flowed in the insulation pipeline 900 for more than 90 seconds to enhance the inactivation effect.

[0064] In some embodiments, the outer wall of the insulation pipeline 900 is provided with an insulation jacket. In other embodiments, the insulation pipeline 900 is disposed in an insulation box to insulate the waste liquid in the insulation pipeline 900 .

[0065] In some embodiments, a temperature sensor 910 is provided near the first outlet 430 of the insulation pipeline 900. The temperature sensor 910 is electrically connected to the temperature regulating valve 443. The temperature sensor 910 can monitor the temperature of the waste liquid that is about to enter the insulation pipeline 900. If the temperature sensor 910 detects that the temperature of the high-temperature waste liquid after heating has not reached the inactivation temperature, a signal is sent to the temperature regulating valve 443, so that the temperature regulating valve 443 increases the amount of steam entering the steam delivery pipe 440, thereby increasing the heating temperature of the heating module 400.

[0066] In addition, some modules in the above embodiments are connected through pipelines, which has low cost and reliable connection effect.

[0067] Another embodiment of the present application provides a pharmaceutical system, which includes the waste liquid treatment equipment as described above.

[0068] The pharmaceutical system includes a waste liquid treatment device as in any of the above embodiments, wherein the waste liquid that has not been inactivated can enter the heating chamber 410 from the first pipeline 100 through the first inlet 420, and the heating module 400 heats the waste liquid in the heating chamber 410 to inactivate the waste liquid, and the heated high-temperature waste liquid enters the second pipeline 200 from the first outlet 430 to discharge the waste liquid, and in this process, the heat absorption module 500 can absorb the heat of the high-temperature waste liquid in the second pipeline 200 and transfer the heat to the preheating module 300 disposed on the first pipeline 100. , so that the preheating module 300 preheats the unheated waste liquid in the first pipeline 100, and the preheated waste liquid enters the heating chamber 410 of the heating module 400 from the first inlet 420. Since the temperature of the preheated waste liquid is higher than that of the waste liquid at room temperature, the heating module 400 consumes less energy to heat the waste liquid to the inactivation temperature and thus inactivates the waste liquid; compared with traditional technologies, the pharmaceutical system including the above-mentioned waste liquid treatment equipment consumes less energy when inactivating the waste liquid, thereby reducing the cost of waste liquid inactivation treatment.

[0069] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
