Description

Technical Field

[0001] This utility model belongs to the field of steam preparation technology, specifically relating to a pure steam generator. Background Technology

[0002] A pure steam generator is a specialized steam production device that uses purified water as a raw material to produce pure, impurity-free steam through a specific heating and evaporation process. This steam has wide applications in various fields such as medicine, biotechnology, and food processing. Especially in situations requiring a sterile environment, pure steam is an indispensable disinfection and sterilization medium.

[0003] Since the working principle of a pure steam generator is to heat water and convert it into steam, some non-condensable gases may be generated during this process, such as gases dissolved in water (such as oxygen, carbon dioxide, etc.). However, in the current technical solution, these non-condensable gases are not eliminated with the condensation of steam, but are directly introduced into the subsequent use system with the steam.

[0004] The presence of non-condensable gases can severely impact the quality of pure steam. For example, oxygen can react chemically with equipment surfaces, leading to corrosion and shortening equipment lifespan. Furthermore, it affects the heat transfer efficiency of pure steam, thereby reducing the overall operating efficiency of the equipment.

[0005] Therefore, the pure steam generators currently on the market have the problem of not being able to effectively remove the non-condensable gases generated during the steam generation process, resulting in the pure steam not meeting the purity standards. They cannot fully meet the requirements of some industrial applications with extremely high steam purity requirements, such as aseptic processing in the pharmaceutical industry and high-temperature sterilization in the food industry. Utility Model Content

[0006] The purpose of this invention is to provide a pure steam generator that solves the technical problem that existing pure steam generators cannot effectively remove non-condensable gases generated during steam generation, resulting in substandard purity of the generated pure steam.

[0007] This utility model discloses a pure steam generator, comprising:

[0013] The preheater has its air inlet connected to the air outlet of the evaporator via a pipeline;

[0014] The preheating water pipeline is connected to the outlet of the preheater at one end and splits into two branches at the other end.

[0021] Based on the above technical solution, the solution of this application can be further improved as follows:

[0022] Preferably, a first regulating valve and a first check valve are connected in series at the end of the non-condensable gas venting pipeline near the evaporator, a second check valve is connected in series on the circulating water pipeline between the evaporator and the circulating pump, and a third check valve is connected in series on the purified water pipeline.

This solution adds steam quality monitoring and non-conforming steam treatment functions, further improving the purity of the steam and the safety of the system.

[0025] Preferably, the inlet of the heat exchanger is connected to the purified water pipeline via an inlet pipe, and the outlet of the heat exchanger is connected to the wastewater pipeline via an outlet pipe. This design allows purified water to be used for condensation in the heat exchanger, improving the independent operation capability of the entire device.

[0026] Preferably, a fifth one-way valve is connected in series on the inlet pipe, and a second regulating valve is connected in series on the outlet pipe.

[0027] Preferably, one branch of the sewage discharge pipeline is connected in series with a sixth one-way valve and then connected to the overflow port of the buffer tank; the other branch is connected in series with a second drain valve and then connected to the overflow port of the separator.

[0031] Preferably, a pressure balancing device is installed on the pure steam pipeline; this solution is used to automatically adjust and maintain the pressure stability within the pure steam pipeline, thereby ensuring continuous and stable steam output.

[0033] 1. This application pre-exhausts air from the pipeline by setting an exhaust valve, atomizes purified water entering the evaporator into tiny water droplets by setting an atomizer, and sets up a non-condensable gas exhaust pipeline, thereby efficiently removing non-condensable gases generated during the steam generation process during the circulating evaporation process, thus greatly improving the purity of pure steam and enhancing product quality.

[0034] 2.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0044] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0045] Example:

[0046] like Figure 1 As shown in the figure, this application discloses a pure steam generator for preparing pure steam. Its specific structure includes: an evaporator 1, a steam supply pipeline 2, a separator 3, a buffer tank 4, a circulating water pipeline 5, a preheater 6, a preheated water pipeline 7, a buoyancy valve 8, a purified water pipeline 9, a wastewater discharge pipeline 10, a non-condensable gas discharge pipeline 11, and a pure steam pipeline 12.

[0047] An atomizer 101 is installed at the water inlet of the evaporator 1, which can atomize the incoming purified water into tiny water droplets, thereby greatly increasing the contact area between the water and the heat source.

[0048] The steam supply line 2 is connected to the air inlet of the evaporator 1 to provide the necessary heat source, such as industrial steam, to the evaporator 1 to ensure that its interior reaches a suitable evaporation temperature.

[0049] Separator 3 is installed at the lower end of evaporator 1 to efficiently separate the generated steam from the unevaporated purified water, ensuring that the output steam has high purity.

[0050] The buffer tank 4 is equipped with a first water inlet and a second water inlet. The first water inlet is connected to the outlet of the separator 3 through a pipeline and is used to temporarily store the water flowing out of the separator 3 to balance the water flow pressure in the system.

[0051] One end of the circulating water pipeline 5 is connected to the outlet of the buffer tank 4, and the other end is connected to the inlet of the evaporator 1 via a circulating pump 501. The circulating pump 501 drives the water back to the evaporator 1 for re-evaporation. An exhaust valve 502 is installed to discharge the air in the pipeline.

[0052] The air inlet of the preheater 6 is connected to the air outlet of the evaporator 1 through a pipeline. It is used to preheat the purified water that is about to enter the evaporator 1 with the secondary steam after the evaporator 1 has been used, thereby improving the evaporation efficiency and avoiding heat waste.

[0053] One end of the preheating water pipe 7 is connected to the outlet of the preheater 6, and the other end is divided into two branches. One branch is connected to the circulating water pipe 5 after being connected in series with the pressure valve 701, and the other branch is connected to the second inlet of the buffer tank 4 to replenish the preheated purified water.

[0054] The buoyancy valve 8 is installed inside the buffer tank 4 and can close the second inlet of the buffer tank 4 after the buffer tank 4 is full to prevent water from overflowing.

[0055] The purified water pipeline 9 is connected to the inlet of the preheater 6 and is used to supply purified water to the preheater 6 to supplement the consumption of the circulating evaporation system.

[0056] A branch of the sewage pipe 10 is connected in series with the first steam trap 1001 and then connected to the air outlet of the preheater 6. It is used to discharge the condensate generated in the preheater 6 and prevent steam leakage through the first steam trap 1001, thereby avoiding heat waste.

[0057] One end of the non-condensable gas venting pipe 11 is connected to the non-condensable gas vent of the evaporator 1, and the other end is divided into two branches. One branch extends upward to vent non-condensable gas, and the other branch is connected to the sewage venting pipe 10 to vent condensate.

[0058] The pure steam pipeline 12 is connected to the steam outlet of the separator 3 and is used to transport the generated pure steam.

[0059] The working principle of the above technical solution is as follows:

[0060] Purified water enters the inlet of preheater 6 through purified water pipeline 9. The purified water entering preheater 6 is preheated by the secondary steam generated by evaporator 1. The preheated water enters the second inlet of buffer tank 4 through a branch of preheated water pipeline 7. It then mixes with return water in buffer tank 4 and enters circulating water pipeline 5. If buffer tank 4 is full, buoyancy valve 8 will close the second inlet of buffer tank 4. As a result, the pressure in preheated water pipeline 7 will gradually increase, causing pressure valve 701 to gradually open. At this time, the preheated water will directly enter circulating water pipeline 5 through another branch of preheated water pipeline 7.

[0061] The mixed water entering the circulating water pipe 5 will be pumped by the circulating pump 501 into the inlet of the evaporator 1, and during this process, the air in the pipe will be discharged through the exhaust valve 502, thereby reducing the formation of non-condensable gases.

[0062] The mixed water entering the evaporator 1 is atomized into tiny water droplets by the atomizer 101. These water droplets exchange heat with the industrial steam supplied by the steam pipeline 2 inside the evaporator 1, and are thus rapidly evaporated to form steam. The generated steam and the unevaporated water droplets are efficiently separated by the separator 3. The unevaporated water droplets enter the buffer tank 4 through the first inlet of the buffer tank 4, and then return to the evaporator 1 for re-evaporation through the circulating water pipeline 5 and the circulating pump 501, thus forming a cycle. The generated steam is output from the system through the pure steam pipeline 12 for subsequent use.

[0063] When the atomized water droplets in the evaporator 1 are heated and evaporated to form steam, the gas dissolved in the water will also separate out, thereby generating non-condensable gas. After being heated, the non-condensable gas will rise to the top of the evaporator 1 and enter the non-condensable gas exhaust pipe 11 through the non-condensable gas exhaust port. Then, the non-condensable gas will be directly discharged to the outside through the upward-extending branch. A small portion of the steam that enters with it will form condensate due to cooling and finally flow to the sewage exhaust pipe 10 through another branch.

[0064] Industrial steam enters the inlet of evaporator 1 through steam supply pipeline 2, and then undergoes heat exchange inside evaporator 1. The secondary steam formed after heat exchange enters the inlet of preheater 6 through pipeline from the outlet of evaporator 1. Then, purified water is preheated inside preheater 6. The condensate formed by the cooling of secondary steam then enters the wastewater discharge pipeline 10 through the outlet of preheater 6 and is discharged. The first steam trap 1001 can prevent secondary steam leakage, thereby avoiding heat waste.

[0065] This invention pre-exhausts air from the pipeline by setting an exhaust valve 502, atomizes purified water entering the evaporator 1 into tiny water droplets by setting an atomizer 101, and sets a non-condensable gas exhaust pipeline 11. This allows for the efficient removal of non-condensable gases generated during the steam generation process during the circulating evaporation process, thereby significantly improving the purity of the pure steam and enhancing product quality.

[0066] In some embodiments, such as Figure 1 As shown, the non-condensable gas discharge pipeline 11 is connected in series with a first regulating valve 1101 and a first check valve 1102 at the end near the evaporator 1. The circulating water pipeline 5 between the evaporator 1 and the circulating pump 501 is connected in series with a second check valve 503. The purified water pipeline 9 is connected in series with a third check valve 901.

[0067] The flow rate can be controlled by setting the first regulating valve 1101 to prevent steam from being discharged as well; the first one-way valve 1102 ensures that the gas is discharged from the system in one direction, preventing external air from entering the steam evaporator 1; the second one-way valve 503 ensures that water will not flow back into the buffer tank 4 when the circulating pump 501 is not started; and the third one-way valve 901 ensures that purified water enters the system in one direction and is not affected by the internal pressure of the system to prevent backflow.

[0068] The above settings enhance the system's controllability, improve its safety and stability, and ensure the efficient, stable, and pure preparation of steam.

[0069] In some embodiments, such as Figure 1 As shown, one end of the pure steam pipeline 12 is connected to the steam outlet of the separator 3, and the other end splits into three branches, each performing a different function:

[0070] The first branch is connected in series with the first on / off valve 1201, which is used to output qualified pure steam for subsequent use;

[0071] The second branch is connected in series with a second on / off valve 1202, which is used to output unqualified pure steam for subsequent processing.

[0072] The third branch, which connects to the sewage pipe 10 via a heat exchanger 1203, a collection pipe 1204, and a fourth check valve 1205 in series, is used to monitor steam quality and treat condensate.

[0073] The collection pipe 1204 is equipped with a conductivity meter 1206, which is used to collect the conductivity of the condensate water, and to serve as the basis for switching the first on / off valve 1201 and the second on / off valve 1202.

[0074] The working principle of the above technical solution is as follows:

[0075] The pure steam entering the pure steam pipeline 12 first enters the heat exchanger 1203 through the third branch, and then is condensed into water and enters the collection pipe 1204. The conductivity data is then collected in real time by the conductivity meter 1206 installed on it, and finally discharged into the sewage pipeline 10 through the fourth one-way valve 1205.

[0076] Understandably, the function of the fourth check valve 1205 is to ensure that condensate is discharged into the sewage pipe 10 in one direction, to prevent the internal pressure of the system from affecting the direction of water flow, and to prevent external sewage from flowing back, which would cause the pure steam in the pure steam pipe 12 to be contaminated.

[0077] According to the data collected by the conductivity meter 1206, if the conductivity of the condensate is lower than the preset standard (indicating high steam purity), the control system will open the first on / off valve 1201 and close the second on / off valve 1202, so that qualified pure steam is output through the first branch for subsequent use; if the conductivity of the condensate is higher than the preset standard (indicating that the steam may contain impurities), the control system will close the first on / off valve 1201 and open the second on / off valve 1202, so that unqualified pure steam is output through the second branch for subsequent processing.

[0078] The refined design of the pure steam pipeline 12 described above adds steam quality monitoring and non-conforming steam treatment functions, further improving the purity of the steam and the safety of the system.

[0079] In some embodiments, such as Figure 1 As shown, the inlet of heat exchanger 1203 is connected to purified water pipeline 9 through inlet pipe 13, and the outlet of heat exchanger 1203 is connected to sewage pipeline 10 through outlet pipe 14.

[0080] Part of the purified water in the purified water pipeline 9 enters the inlet of the heat exchanger 1203 through the inlet water pipeline 13, and then the steam is condensed in the heat exchanger 1203 through heat exchange. After that, it enters the outlet water pipeline 14 from the outlet of the heat exchanger 1203, and finally is discharged into the sewage pipeline 10.

[0081] The above setup allows purified water to be used for condensation in heat exchanger 1203, improving the independent operation capability of the entire device.

[0082] Based on the above embodiments, a fifth one-way valve 1301 is connected in series on the water inlet pipe 13 to ensure that purified water enters the water inlet pipe 13 in one direction and then flows into the water inlet of the heat exchanger 1203, ensuring that the purified water will not backflow due to changes in the internal pressure of the system and avoiding contamination of the purified water. A second regulating valve 1401 is connected in series on the water outlet pipe 14 to control the flow rate and ensure that the amount of purified water used for condensation is appropriate and to avoid waste.

[0083] The above settings ensure that purified water will not flow back due to changes in internal system pressure, preventing contamination of the purified water and ensuring that the amount of purified water used for condensation is appropriate, thus avoiding waste.

[0084] In some embodiments, such as Figure 1 As shown, one branch of the sewage discharge pipeline 10 is connected to the overflow port of the buffer tank 4 via a sixth check valve 1002 in series; the other branch is connected to the overflow port of the separator 3 via a second drain valve 1003 in series.

[0085] When the water level in buffer tank 4 exceeds the set value, the excess water will flow into the sewage pipe 10 through the sixth one-way valve 1002, which not only ensures the stable operation of the system, but also prevents sewage from flowing back into buffer tank 4 and avoids pollution.

[0086] When the water level in separator 3 rises to near the steam outlet, excess water will flow from the overflow port into the sewage pipe 10 through the second steam trap 1003; the second steam trap 1003 can prevent steam leakage and ensure that the system can operate normally.

[0087] The above settings enable overflow protection for separator 3 and buffer tank 4, improving the safety and stability of the system.

[0088] In some embodiments, such as Figure 1 As shown, a filter valve 201, a shut-off valve 202, an electrically controlled regulating valve 203 and a safety valve 204 are connected in series on the steam supply pipeline 2, and a pressure regulator 1207 is installed on the pure steam pipeline 12.

[0089] The filter valve 201 is used for preliminary filtration to remove impurities and particulate matter that may be present in the steam, ensuring the quality of the steam entering the system; the shut-off valve 202 is used to quickly cut off the steam supply when the system needs maintenance or emergency shutdown, ensuring system safety; the electrically controlled regulating valve 203 is used to automatically adjust the steam flow according to system requirements, ensuring stable pressure and temperature in the evaporator 1; the safety valve 204 is used to automatically open and release excess pressure when the internal pressure of the system exceeds the set value, preventing the system from being damaged due to overpressure.

[0090] A pressure regulator 1207 is installed on the pure steam pipeline 12 to monitor the pressure change of pure steam in real time. The control system can judge the steam flow state and system stability based on the data from the pressure regulator 1207, and use this as a basis to control the opening of the electronic control regulating valve 203.

[0091] The above settings improve the stability of steam supply to steam pipeline 2, ensuring the long-term efficient operation of the system.

[0092] In some embodiments, such as Figure 1 As shown, a booster pump 902, a flow valve 903, and a flow meter 904 are connected in series on the purified water pipeline 9.

[0093] The purified water is pressurized by the booster pump 902 to ensure that the purified water can smoothly enter the subsequent system; the flow valve 903 is used to regulate the flow rate of the purified water entering the system to ensure that the system can operate stably, and can be automatically adjusted by the electronic control system according to the system requirements; the flow meter 904 is used to monitor the flow rate of the purified water in real time to ensure that the water flow rate in the system meets the preset requirements.

[0094] The above settings enable a stable supply and flow regulation of purified water, improve the safety and stability of the system, and ensure long-term stable operation of the equipment through continuous monitoring.

[0095] In some embodiments, a first sampling valve 905 is installed on the purified water pipeline 9, and a second sampling valve 1208 is installed on the collection pipe 1204.

[0096] The installation of the first sampling valve 905 on the purified water line 9 allows operators to conveniently collect purified water samples when needed, which helps to monitor the quality of the purified water and ensure that it meets the requirements.

[0097] The installation of the second sampling valve 1208 on the collection pipe 1204 allows operators to easily collect condensate samples, which helps monitor the quality of pure steam, especially the purity of the condensed water. By collecting and analyzing condensate samples, the system's performance can be evaluated, ensuring that the pure steam meets usage requirements.

[0098] The above settings not only make it easier for the equipment to collect samples, but also improve the reliability and stability of the system. By collecting and analyzing samples regularly, problems can be detected in a timely manner, ensuring that the quality of pure steam meets the usage requirements.

[0099] In some embodiments, a pressure balancing device 1209 is installed on the pure steam pipeline 12 to automatically adjust and maintain the pressure stability within the pure steam pipeline 12, thereby ensuring continuous and stable steam output.

[0100] For example, the pressure balancing device 1209 consists of a manual ball valve, a one-way valve, and a breather connected in series. The manual ball valve is used to manually adjust the pressure in the pipeline when needed to ensure that the pressure in the system is stable; the one-way valve ensures that steam can only flow in one direction, preventing backflow and avoiding pollution; the breather is used to automatically adjust and balance the pressure in the system through breathing when the pressure fluctuates in the system.
