[0034] The following further details the present application in conjunction with specific drawings. In the description of this embodiment, unless otherwise specified, the orientation or positional relationship indicated by terms such as "left" and "right" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the present application must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0035] As Figure 1 shown, a low-energy wastewater inactivation system provided by the present invention mainly includes a waste liquid collection tank 100 for storing external biological wastewater. In this embodiment, the external biological wastewater is transported to the waste liquid collection tank 100 through a sealed pipeline to avoid leakage of toxic gases;

[0036] The heating module 300 is connected to the waste liquid collection tank 100, and the heating module 300 is used to heat the wastewater to a preset temperature; in this embodiment, the heating module 300 is heated by hot steam, and the biological wastewater is heated to at least 98 degrees. After experimental verification, all the wastewater is inactivated at a high temperature of 98 degrees and can meet the discharge standard. In this embodiment, the biological wastewater is heated to 100 degrees before entering the heat preservation module;

[0037] The heat preservation module 400 is connected to the heating module 300. The heat preservation module 400 is provided with a heat preservation pipeline, so that after the wastewater is heated to the preset temperature by the heating module 300, the heated wastewater flows in the heat preservation pipeline at a preset flow rate. The heat preservation pipeline is set with a preset length, so that the heated wastewater is heat-preserved for a certain time and then flows out of the heat preservation module 400;

[0038] In this embodiment, by setting the coil structure, the pipeline length of the heat preservation module 300 is maximized under limited space. When the wastewater enters the heat preservation module 400, its temperature is not lower than 98 degrees. By setting a temperature monitoring instrument at the inlet of the heat preservation module 400 to monitor the heated wastewater, there is no heat loss of the wastewater in the heat preservation module 400. After the wastewater flows through the heat preservation module 400 for a certain time, the wastewater can be completely inactivated. In this embodiment, the wastewater needs to flow in the heat preservation module 400 for 15 minutes and then flows out after being inactivated at a high temperature of more than 98 degrees for 15 minutes. At the same time, a temperature monitoring instrument is set at the water outlet end of the heat preservation module 400 to detect the temperature of the wastewater flowing out of the heat preservation module in real time, so as to avoid its temperature being lower than 98 degrees and thus not meeting the discharge standard.

[0039] The sewage storage module 600 is connected to the heat preservation module 400. The sewage storage module 600 is connected to the heat preservation pipeline of the heat preservation module 400, and is used for storing and treating the wastewater after high-temperature inactivation and discharging the inactivated wastewater centrally;

[0040] Among them, it should be particularly noted that a hot water tank 200 is arranged between the waste liquid collection tank 100 and the heating module 300. The hot water tank 200 is used to preheat and raise the temperature of the wastewater flowing from the waste liquid collection tank 100 to the heating module 300; specifically, the hot water tank 200 is the hot water used in daily life. By setting a coil in the hot water tank 200, the wastewater in the waste liquid collection tank 100 is preheated and raised in temperature through the coil in the hot water tank 200, which increases the waste liquid temperature and reduces the temperature difference that the heating module 300 needs to heat, thereby reducing the heating energy consumption. At the same time, a coil is also arranged in the waste liquid collection tank 100. Since in this application, the heating module 300 is heated by steam, the steam after passing through the heating module 300 is connected to the coil arranged in the waste liquid collection tank 100, and the waste heat of the steam is used to preheat and raise the temperature of the wastewater in the waste liquid collection tank 100, further reducing the energy consumption required by the heating module 300;

[0041] Furthermore, since biological wastewater is toxic and cannot be discharged randomly like ordinary wastewater, a leakage prevention module 500 is provided between the heating module 300 and the sewage storage module 600. At the same time, the leakage prevention module 500 is also connected to the heating module 300 and the waste liquid collection tank 100 to achieve wastewater self-circulation. When the wastewater meets the discharge standard, it normally flows to the sewage storage module 600 through the leakage prevention module 500. When the wastewater discharge does not meet the standard, that is, when the wastewater flows out of the heat preservation module 400, the temperature of the wastewater is lower than the preset temperature, that is, the above-mentioned 98 degrees. At this time, there is a great risk of wastewater discharge, which is likely to cause environmental pollution and harm to the people around. Therefore, when the wastewater discharge does not meet the standard, the connection between the leakage prevention module 500 and the sewage storage module 600 is blocked, and the pipeline between the leakage prevention module 500 and the waste liquid collection tank 100 is connected, so as to realize the recycling of wastewater for re-heating and inactivation. Under normal circumstances, the pipeline between the leakage prevention module 500 and the waste liquid collection tank 100 is closed.

[0042] By setting the leakage prevention module 500 and the hot water tank 200 in this application, existing resources are reasonably utilized. While reducing the heating energy loss, it can also ensure that the wastewater does not leak accidentally before reaching the discharge standard, improving the safety performance of the whole device. At the same time, in this application, self-circulation can be realized before maintenance to ensure the safety of the maintenance environment.

[0043] In one embodiment, a first pump body 1011 is provided between the waste liquid collection tank 100 and the hot water tank 200, and a second pump body 201 is provided between the hot water tank 200 and the heating module 300. The wastewater in the waste liquid collection tank 100 flows into the hot water tank 200 through the first pump body 1011, and then the second pump body 201 pumps the wastewater from the hot water tank 200 to the heating module 300 for heating. By setting the above double-pump structure, the pressure of the pipeline can be effectively reduced to stabilize the flow rate of the wastewater in the pipeline. Since the pipeline is relatively long, up to dozens or even hundreds of meters, when a single pump is used to suck the wastewater, the pump body needs to provide a very high rotation speed, which will generate a large pressure on the pipeline. By setting the first water pump 1011 and the second water pump 201 at a certain distance, on the one hand, the pipeline pressure is maintained, and on the other hand, the flow rate of the wastewater in the pipeline is maintained.

[0044] Furthermore, as Figure 2As shown in the figure, in order to avoid the abnormal flow supply of wastewater when the first pump body 1011 is blocked, a first alternative pump 1012 is provided between the waste liquid collection tank 100 and the hot water tank 200. The first alternative pump 1012 and the first pump body 1011 are arranged in parallel. Specifically, it further includes a first valve 10111 provided at the water inlet end of the first pump body 1011, a second valve 10121 provided at the water inlet end of the first alternative pump 1012, and a first controller 1013. The first valve 10111 and the second valve 10121 are in parallel, and the first controller 1013 is electrically connected to the first valve 10111 and the second valve 10121, so as to realize the electric control of the first valve 10111 and the second valve 10121. When the first pump body 1011 is blocked, the first controller 1013 detects that the waste liquid flow rate drops sharply. The first controller 1013 controls the first valve 10111 to close. At the same time, the first controller 1013 controls the second valve 10121 to open, and the first alternative pump 1011 enters the normal working state. By setting the above structure, the fault tolerance of the whole device is improved, and the inactivation process is prevented from stopping due to the blockage of the first pump body 1011. The first valve, the second valve and the first controller are all prior arts and will not be described in detail here.

[0045] Optionally, a standby pump for the second pump body 201 can also be set, and its specific structure and principle are as above, and will not be described in detail here.

[0046] In one embodiment, in order to further utilize the existing resources to preheat the wastewater, a preheating and temperature-rising module is provided between the heating module 300 and the hot water tank 200, as Figure 3 shown, the first water inlet of the preheating heat exchanger 401 is connected to the water outlet end of the coil in the hot water tank 200, the first water outlet of the preheating heat exchanger 401 is connected to the heating module 300, the second water inlet of the preheating heat exchanger 401 is connected to the heat preservation module 400, and the second water outlet of the preheating heat exchanger 401 is connected to the anti-leakage module 500. In this embodiment, the preheating and temperature-rising exchanger 401 is a plate exchanger, which is a prior art and will not be described in detail. In this embodiment, by using the high temperature of the inactivated wastewater to further preheat the wastewater about to flow into the heating module 300, the wastewater flows into the heating module at a higher temperature, so as to further efficiently utilize the existing resources and reduce the energy consumption required for the heating module 300 to heat the wastewater.

[0047] In one embodiment, the heating module 300 includes a first heater 301, a second heater 302, and a steam input structure 304. The steam input structure 304 is in communication with both the first heater 301 and the second heater 302. In the foregoing description, the steam input structure 301 is in communication with the coil in the waste liquid collection tank 100 after passing through the heating module 300, thereby realizing the utilization of steam energy to pre-heat the wastewater in the waste liquid collection tank 100 and reducing the energy consumption required for the heating module 300 to heat up. Among them, a third valve 3011 is provided at the water inlet end of the first heater 301, a fourth valve 3012 is provided at the water outlet end of the first heater 301, a fifth valve 3021 is provided at the water inlet end of the second heater 302, and a sixth valve 3022 is provided at the water outlet end of the second heater 302. The third valve 3011 and the fifth valve 3021 are in parallel, and the fourth valve 3012 and the sixth valve 3022 are in parallel;

[0048] Under normal circumstances, when the third valve 3011 and the fourth valve 3012 are open, the first heater 301 heats during normal operation. At this time, the fifth valve 3021 and the sixth valve 3022 are closed; or when the third valve 3011 and the fourth valve 3012 are closed, the second heater 302 heats during normal operation, and the fifth valve 3021 and the sixth valve 3022 are open. By providing the first heater 301 and the second heater 302, heating failures of the heating module 300 are avoided, so that the wastewater cannot be heated to the preset temperature for inactivation and cannot meet the discharge standard. Providing two heaters increases the alternative options, thus avoiding the interruption of the wastewater inactivation process.

[0049] In one embodiment, when the heating temperature of the wastewater fails to reach the preset temperature, the energy consumption of the heating module 300 needs to be provided at this time. Therefore, an external steam input structure 304 is further included to provide steam to heat the wastewater passing through the heating module 300 through the heating module 300.

[0050] Specifically, as Figure 4 shown, a second controller is provided at the water outlet end of the insulation module 400. The second controller 304 monitors the temperature of the wastewater discharged from the insulation module 400 in real time; a first pneumatic regulating valve 303 is provided between the steam input structure 304 and the heating module 300. The first pneumatic regulating valve 303 is in communication with both the first heater 301 and the second heater 302. The second controller 304 realizes automatic regulation of the first pneumatic regulating valve 303 through real-time temperature detection. When the temperature of the wastewater flowing out of the insulation module 400 is lower than the preset temperature, the second controller 304 adjusts the first pneumatic regulating valve 303 at this time to increase the steam intake ratio, thereby increasing the heating energy of the heating module 300 and enabling the wastewater to reach the preset temperature again after passing through the heating module 300.

[0051] Since one of the heaters of the heating module 300 is a spare structure, a seventh valve 3011 and an eighth valve 3021 are provided at the steam inlet ends of the first heater 301 and the second heater 302, and the seventh valve 3011 and the eighth valve 3021 are in parallel. Under normal circumstances, the seventh valve 3011 is in an open state, and the eighth valve 3021 is in a closed state. When the first heater 301 is damaged, at this time, the seventh valve 3011 closes, the eighth valve 3021 opens, and the second heater 302 enters the normal working state.

[0052] In one embodiment, since the wastewater has a certain toxicity, a leak prevention module 500 is provided to discharge the wastewater that has passed through the heat preservation module 400.

[0053] Specifically, as Figure 5 shown, the leak prevention module 500 includes a first leak prevention valve 501, a second leak prevention valve 502, a third leak prevention valve 503, and a fourth leak prevention valve 504. The water inlet of the first leak prevention valve 501 is connected to the water outlet of the preheating heat exchanger 401. The water inlet of the second leak prevention valve 502 is connected to the water outlet of the first leak prevention valve 501. The water outlet of the second leak prevention valve 502 is communicated with the sewage collection module 600. The water inlet of the third leak prevention valve 503 is respectively communicated with the water outlet of the first leak prevention valve 501 and the water inlet of the second leak prevention valve 501. The water outlet of the third leak prevention valve 503 is communicated with the waste liquid collection tank 100. The water inlet of the fourth leak prevention valve 504 is communicated with the water outlet of the preheating heat exchanger 401. The water outlet of the fourth leak prevention valve 501 is respectively communicated with the waste liquid collection tank 100 and the water outlet of the third leak prevention valve 503. A total leak prevention valve 506 is provided between the preheating exchanger 401 and the leak prevention module 500. When the wastewater flows out of the heat preservation module 400 and its temperature is lower than the preset temperature, the total leak prevention valve 506 is closed at this time.

[0054] Under normal circumstances, the inactivated wastewater flows out through the first leak prevention valve 501 and the second leak prevention valve 502, and the third leak prevention valve 503 and the fourth leak prevention valve 504 are in a closed state. When the wastewater does not meet the discharge standard, the total leak prevention valve 506 is closed, and at the same time, the second leak prevention valve 502 is closed. A third controller 505 provided at the water outlet end of the first leak prevention valve 501 is used to detect the pressure at the water outlet end of the first leak prevention valve 501. When the pressure decreases, since the third controller 505 is electrically connected to the third leak prevention valve 503, the third controller 505 controls the third leak prevention valve 503 to open. At this time, the wastewater that does not meet the discharge standard flows from the third leak prevention valve 503 to the waste liquid collection tank 100, thereby preventing the wastewater from being directly discharged to the outside.

[0055] To maintain the air pressure balance inside the waste liquid collection tank 100, a first breather 1031 and a second breather 1032 are further provided on the waste liquid collection tank 100. The first breather 1031 and the second breather 1032 are connected in parallel and are both connected to the waste liquid collection tank 100. Filters are provided on both the first breather 1031 and the second breather 1032. The filters are used for gas filtration to prevent harmful gases inside the waste liquid collection tank 100 from being directly discharged.

[0056] In one embodiment, the device further includes a cooling exchanger and a cooling system. The cooler is arranged between the water outlet of the second leak-proof valve 502 and the sewage storage module 600. The water supply path 6031 and the return path 6032 of the cooling system are both connected to the cooling exchanger, as Figure 6 shown, so as to reduce the high-temperature wastewater to normal temperature for discharge.

[0057] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made. These improvements and refinements should also be regarded as the protection scope of the present invention.
