Description

Technical Field

[0001] This utility model relates to the field of disinfection system technology, specifically a biological fluid continuous disinfection system. Background Technology

[0002] Existing disinfection systems mostly use batch disinfection, which has disadvantages such as high manufacturing costs, high energy consumption, and long sterilization time (slow heating and cooling rates). Utility Model Content

[0003] The purpose of this invention is to provide a biological fluid continuous disinfection system to solve the problems mentioned above, such as the fact that existing disinfection systems mostly use batch disinfection, have high manufacturing costs, high operating energy consumption, and long sterilization time (slow heating and cooling rates).

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A continuous disinfection system for biological fluids includes a biological fluid, a feeding system, a preheating system, a heating system, a maintenance system, and a cooling system.

[0006] The feeding system includes a storage tank, a level sensor, a cleaning fluid, a first industrial steam, a filter, a transfer pump, and a flow meter. The biofluid enters the storage tank through a pipeline. The level sensor is installed inside the storage tank and is used to monitor the liquid level of the biofluid. The storage tank outlet is connected in sequence to a filter, a transfer pump, and a flow meter through a pipeline. The transfer pump is used to transport the biofluid flowing out of the storage tank to the preheating system. The flow meter is electrically connected to the storage tank outlet control valve. The flow meter controls the storage tank outlet control valve based on the flow rate of the biofluid in the pipeline.

[0007] The preheating system includes at least one preheater. The biofluid delivered by the delivery pump flows through the preheater. The biofluid flowing through the maintenance system flows through the preheater via a pipeline. The biofluid flowing through the maintenance system preheats the biofluid delivered by the delivery pump.

[0008] The heating system includes a heater, a second industrial steam source, and a proportional control valve. The preheated biological fluid flows through the heater. The heater is connected to the second industrial steam source via a pipeline. The hot steam provided by the second industrial steam source flows through the heater to heat the preheated biological fluid. The steam content provided by the second industrial steam source is controlled by the proportional control valve.

[0009] The maintenance system includes a maintenance pipe, a maintenance tank, and a temperature sensor. The heated biofluid flows through the maintenance pipe or maintenance tank. The temperature sensor is connected to the maintenance pipe or maintenance tank via a pipe and is electrically connected to the proportional regulating valve to control the content of the hot steam provided by the second industrial steam.

[0010] The cooling system includes a cooler, a cooling water inlet pipe, a cooling water outlet pipe, and a discharge tank. The biofluid flowing through the maintenance system passes through the temperature sensor and then flows through the cooler via a pipe. The cooler cools the biofluid, and biofluid that meets the requirements flows into the discharge tank, while biofluid that does not meet the requirements flows into the storage tank via a pipe.

[0011] As a further aspect of this invention: the temperature sensor controls the heating temperature of the preheated biological fluid by controlling the content of hot steam provided by the second industrial steam through a proportional regulating valve based on the temperature of the biological fluid flowing through the maintaining pipe or maintaining tank, thereby ensuring that the temperature of the biological fluid flowing through the maintaining pipe or maintaining tank meets the requirements for disinfection or sterilization.

[0012] As a further embodiment of this utility model: the cleaning fluid and the first industrial steam enter the storage tank through pipelines, and the storage tank performs self-cleaning by the cleaning fluid and self-disinfection by the first industrial steam.

[0013] As a further aspect of this invention: the filter is used to filter impurities in the biological fluid to protect the delivery pump.

[0014] As a further embodiment of this utility model: the cooling water inlet pipe and the cooling water outlet pipe are respectively connected to the cooler through pipes. The cooling water inlet pipe delivers cooling water into the cooler. The cooling water passes through the outer wall of the pipe through which the biological fluid flows, cooling the biological fluid inside. The cooling water is discharged through the cooling water outlet pipe.

[0015] As a further aspect of this invention: the diameter of the maintaining tube or maintaining tank is larger than the diameter of the connecting pipe, so as to reduce the flow rate of the biological fluid and achieve the function of maintaining the biological fluid at a high temperature for a period of time.

[0016] As a further aspect of this invention: after the temperature of the biofluid flowing through the cooler reaches the set temperature, it flows into the discharge tank through a pipe; the biofluid that has not reached the set temperature flows into the storage tank through a pipe.

[0017] As a further aspect of this utility model: the biological fluid flowing through the maintenance system flows through the preheater via a pipeline, which can preheat the biological fluid delivered by the delivery pump to achieve the purpose of initial cooling.

[0018] As a further embodiment of this utility model: the storage tank, cooler, heater and holding tank are all connected to a drain pipe.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] In this invention, once the set height is reached, the liquid level sensor controls the start of the delivery pump. The delivery pump draws the biofluid from the storage tank through the control valve. The biofluid then passes through a filter and is filtered before flowing back through the delivery pump. Next, the biofluid flows through a flow meter, which monitors the flow rate data and adjusts the storage tank outlet control valve based on the data to regulate the flow rate.

[0021] In this invention, the biological fluid flows through a pipe into a preheater. There can be more than one preheater, with multiple stages to achieve the optimal preheating effect. The biological fluid flows through the preheater through the pipe, and at the same time, the high-temperature biological fluid that subsequently flows through the maintenance system also flows through the preheater through the pipe. The two biological fluids undergo sufficient heat exchange in the preheater, causing the temperature of the low-temperature biological fluid to rise and the temperature of the high-temperature biological fluid to fall. This can reduce manufacturing costs and operating energy consumption. Due to the use of preheating and precooling, the subsequent heating and cooling rates are accelerated.

[0022] In this invention, the preheated biological fluid flows through a pipe into a heater, while a second industrial steam supply provides hot steam to the heater to heat the preheated biological fluid. Due to the preheating process, the heating rate is accelerated. The proportional regulating valve can control the heating temperature of the biological fluid by controlling the steam content provided by the second industrial steam.

[0023] In this invention, the temperature sensor is connected to the maintenance pipe or maintenance tank via a pipeline. Based on the temperature of the biological fluid flowing through the maintenance pipe or maintenance tank, the temperature sensor controls the content of hot steam provided by the second industrial steam through a proportional regulating valve to control the heating temperature of the preheated biological fluid, ensuring that the temperature of the biological fluid flowing through the maintenance pipe or maintenance tank meets the requirements for disinfection or sterilization.

[0024] In this invention, the high-temperature biological fluid flowing through the temperature sensor passes through a pipeline and then through a preheater, achieving the aforementioned heat exchange process with the low-temperature biological fluid. After the heat exchange, the temperature of the high-temperature biological fluid decreases, thus achieving preliminary cooling before subsequent cooling and reducing the energy consumption of operation.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example

[0029] A continuous disinfection system for biological fluids includes a biological fluid 1, a feeding system, a preheating system, a heating system, a maintenance system, and a cooling system;

[0030] The feeding system includes a storage tank 2, a liquid level sensor, a cleaning fluid 3, a first industrial steam 4, a filter 5, a transfer pump 6, and a flow meter 7. Before the entire system is in operation, the cleaning fluid 3 enters the storage tank 2 through a pipeline to clean the storage tank 2. The first industrial steam 4 introduces high-temperature hot steam into the storage tank 2 to disinfect the storage tank 2.

[0031] Biofluid 1 enters the storage tank 2 through a pipeline. As time goes by, the liquid level of biofluid 1 in the storage tank 2 keeps increasing. The liquid level sensor monitors the liquid level of biofluid 1 at all times. When the set height is reached, the liquid level sensor controls the transfer pump 6 to start. The transfer pump 6 sends biofluid 1 out of the storage tank 2 through the control valve. After flowing out, biofluid 1 passes through the filter 5 and is filtered by the filter 5 before flowing back to the transfer pump 6. Then, biofluid 1 flows through the flow meter 7. The flow meter 7 monitors the flow data and adjusts the outlet control valve of the storage tank 2 according to the data to regulate the flow.

[0032] The biological fluid 1 flows through a pipe into the preheater 8. There can be more than one preheater 8, and multiple stages of preheaters 8 can be set up to achieve the optimal preheating effect. The biological fluid 1 flows through the preheater 8 through the pipe. At the same time, the high-temperature biological fluid 1 that subsequently flows through the maintenance system also flows through the preheater 8 through the pipe. The two biological fluids 1 undergo sufficient heat exchange in the preheater 8. The temperature of the low-temperature biological fluid 1 rises and the temperature of the high-temperature biological fluid 1 falls, which can reduce manufacturing costs and reduce operating energy consumption. Due to the use of preheating and precooling, the subsequent heating and cooling rates are accelerated.

[0033] The preheated biological fluid 1 flows through the heater 9 through the pipe. At the same time, the second industrial steam 10 provides hot steam to the heater 9 to heat the preheated biological fluid 1. Due to the use of preheating, the heating rate is accelerated. The proportional regulating valve 11 can control the heating temperature of the biological fluid 1 by controlling the steam content provided by the second industrial steam 10.

[0034] The biological fluid 1 heated by heater 9 enters the maintenance pipe 12 or maintenance tank 13 through the pipe. Since the diameter of the maintenance pipe 12 or maintenance tank 13 is larger than the diameter of the connected pipe, the flow rate of the biological fluid 1 will decrease after entering the maintenance pipe 12 or maintenance tank 13, so as to achieve the function of maintaining the biological fluid 1 at a high temperature for a period of time.

[0035] Temperature sensor 14 is connected to the holding pipe 12 or holding tank 13 via a pipeline. Based on the temperature of the biological fluid 1 flowing through the holding pipe 12 or holding tank 13, temperature sensor 14 controls the heating temperature of the preheated biological fluid 1 by controlling the content of hot steam provided by the second industrial steam 10 through the proportional regulating valve 11, so as to ensure that the temperature of the biological fluid 1 flowing through the holding pipe 12 or holding tank 13 meets the requirements for disinfection or sterilization.

[0036] Next, the high-temperature biological fluid 1 flowing through the temperature sensor 14 flows through the preheater 8 via the pipeline, realizing the heat exchange process mentioned above with the low-temperature biological fluid 1. After the heat exchange, the temperature of the high-temperature biological fluid 1 will decrease, and the initial cooling will be carried out before subsequent cooling, thereby reducing the energy consumption of operation.

[0037] Then, the biological fluid 1 flowing through the preheater 8 flows through the cooler 15 through the pipe. At the same time, the cooling water inlet pipe 16 delivers cooling water into the cooler 15. The cooling water passes through the outer wall of the pipe through which the biological fluid 1 flows, cooling the biological fluid 1 inside. The biological fluid 1 that reaches the set temperature flows into the discharge tank 18, while the biological fluid 1 that does not reach the set temperature flows into the storage tank 2 through the pipe. Finally, the cooling water is discharged through the cooling water outlet pipe 17.

[0038] Storage tank 2, cooler 15, heater 9 and holding tank 13 are all connected to drain pipe 19 for discharging internal waste.

[0039] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
