Description

Technical Field

[0001] This application relates to the field of water distributor technology, and in particular to an electrically controlled negative pressure water distribution device for a hydrolysis acidification tank. Background Technology

[0002] In wastewater treatment processes, hydrolysis acidification is a hydrolysis acidification technology that can be produced under anaerobic conditions. It makes up for the shortcomings of simply using aerobic biological treatment technology, and is therefore widely used in the treatment of domestic sewage, urban sewage and industrial wastewater.

[0003] Hydrolysis acidification treatment utilizes a hydrolysis acidification tank, which is also known as a degradation tank. Typically, wastewater is introduced into the hydrolysis acidification tank via a water distributor, such as a pulse-type water distributor.

[0004] Once the liquid level in the pulse-type water distributor reaches the predetermined height, the wastewater to be degraded is automatically drawn into the hydrolysis acidification tank under siphon action. However, because the pulse-type water distributor cannot adjust the pulse time and pulse water volume on its own, once it is manufactured, the pulse time and pulse water volume cannot be adjusted, thus affecting the water distribution effect of the hydrolysis acidification tank. Utility Model Content

[0005] This application provides an electrically controlled negative pressure water distribution device for a hydrolysis acidification tank to solve the problems existing in related technologies. The technical solution is as follows:

[0006] This application provides an electronically controlled negative pressure hydrolysis acidification tank water distribution device, including:

[0007] A wastewater storage device, wherein the wastewater storage device has a wastewater storage tank;

[0008] A siphonic water pipe, wherein the water intake end of the siphonic water pipe extends into the sewage storage tank, and the water outlet end of the siphonic water pipe extends out of the sewage storage tank;

[0009] A siphon hood is provided above the water intake end and is used to form a siphon cavity with the liquid surface of the sewage storage device.

[0010] A suction tube, wherein the suction end of the suction tube is inserted into the siphon cavity and located above the water suction end, or the suction end of the suction tube is inserted into the siphon cloth water pipe; the discharge end of the suction tube is located outside the siphon cavity and the siphon cloth water pipe, and is used to connect to a negative pressure power source.

[0011] In one embodiment, the suction end is inserted into the siphon cloth water pipe and positioned downwards.

[0012] In one embodiment, the electrically controlled negative pressure hydrolysis acidification tank water distribution device further includes a liquid level sensor, which is used to monitor whether the liquid level has reached the water absorption end.

[0013] In one embodiment, the liquid level sensor is located outside the siphon cavity; or, the liquid level sensor is located inside the siphon cavity.

[0014] In one embodiment, the liquid level sensor is disposed inside the siphon cavity, and there are multiple liquid level sensors arranged sequentially along the height direction of the siphon water distribution pipe.

[0015] In one embodiment, the electrically controlled negative pressure hydrolysis acidification tank water distribution device further includes a control system;

[0016] The suction tube is connected to a negative pressure power source;

[0017] The suction end is inserted into the siphon cavity and is positioned downwards;

[0018] The electrically controlled negative pressure hydrolysis acidification tank water distribution device also includes a liquid level sensor, which is installed inside the siphon water distribution pipe;

[0019] Both the negative pressure power source and the liquid level sensor are electrically connected to the control system.

[0020] In one embodiment, the negative pressure power source is located outside the sewage storage tank.

[0021] In one embodiment, the negative pressure power source is a water ring vacuum pump.

[0022] In one embodiment, the electrically controlled negative pressure hydrolysis acidification tank water distribution device further includes a degradation tank, and the discharge end extends into the degradation tank.

[0024] In one embodiment, the opening of the siphon hood is arranged downwards, or the opening of the siphon hood is arranged horizontally.

[0025] The advantages or beneficial effects of the above technical solutions include at least the following:

[0026] By inserting the suction end of the suction pipe into the siphon chamber and positioning it above the water intake end, or by inserting the suction end of the suction pipe into the siphon cloth pipe and positioning the discharge end of the suction pipe outside the siphon chamber and the siphon cloth pipe, a negative pressure can be generated within the siphon chamber of the siphon hood under the influence of a negative pressure power source. This forces the wastewater in the wastewater storage tank of the wastewater storage device into the suction pipe for introduction into the degradation tank. Since this process can be electrically controlled by a negative pressure power source, the wastewater in the wastewater storage tank can be pumped into the degradation tank more flexibly, allowing for more flexible control of the wastewater extraction volume and extraction time.

[0031] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0032] An electrically controlled negative pressure hydrolysis acidification tank water distribution device includes: a sewage storage device 1, a siphon water distribution pipe 2, a siphon cover 3, and a suction pipe 4.

[0033] The wastewater storage device 1 has a wastewater storage tank 11, which is used to store external wastewater. The wastewater is then sent to a degradation tank 7, which is specifically a hydrolysis acidification tank, through which the wastewater is degraded.

[0034] The suction end 21 of the siphon cloth water pipe 2 extends into the sewage storage tank 11, and the outlet end 22 of the siphon cloth water pipe 2 extends out of the sewage storage tank 11 and then into the degradation tank 7.

[0035] The siphon hood 3 is installed above the water intake end 21. The siphon hood 3 is used to form a siphon cavity 31 with the liquid surface of the sewage storage device 1. When the air pressure in the siphon cavity 31 decreases or decreases instantaneously, the sewage in the sewage storage tank 11 will continue to flow to the hydrolysis acidification tank under the siphon effect until the liquid level in the sewage storage tank 11 drops below the siphon hood 3.

[0036] The suction end 41 of the suction tube 4 is inserted into the siphon cloth water pipe 2, and the discharge end 42 of the suction tube 4 is located outside the siphon chamber 31 and the siphon cloth water pipe 2, and is used to connect to the negative pressure power source 5. As an alternative arrangement, in other embodiments, the suction end 41 of the suction tube 4 is inserted into the siphon chamber 31 and located above the water suction end 21.

[0037] During operation, once the liquid level in the sewage storage tank 11 submerges the bottom of the siphon hood 3, thus forming the siphon cavity 31, the electrically controlled negative pressure hydrolysis acidification tank water distribution device is ready to pump the sewage from the sewage storage tank 11 to the degradation tank 7, regardless of whether the liquid level in the sewage storage tank 11 continues to rise or remains unchanged. Specifically, negative pressure is generated by the negative pressure power source 5, which reduces or momentarily lowers the air pressure in the siphon cavity 31, causing the liquid level in the siphon cavity 31 to rise until it reaches the suction end 21 of the siphon water distribution pipe 2. Under the siphon effect, the sewage continuously flows from the suction end 21 of the siphon water distribution pipe 2 to the outlet end 22 of the siphon water distribution pipe 2 until the liquid level in the sewage storage tank 11 is lower than the bottom of the siphon hood 3.

[0038] Thus, by inserting the suction end 41 of the suction pipe 4 into the siphon chamber 31 and positioning it above the suction end 21, or by inserting the suction end 41 of the suction pipe 4 into the siphon cloth pipe 2 and positioning the discharge end 42 of the suction pipe 4 outside the siphon chamber 31 and the siphon cloth pipe 2, under the influence of the negative pressure power source 5, a negative pressure can be generated in the siphon chamber 31 of the siphon hood 3, thereby forcing the sewage in the sewage storage tank 11 of the sewage storage device 1 into the suction pipe 4 and into the degradation tank 7. Since this process can be electrically controlled by the negative pressure power source 5, the sewage in the sewage storage tank 11 can be pumped into the degradation tank 7 more flexibly, allowing for more flexible control of the sewage extraction volume and extraction time.

[0039] It should be noted that when the negative pressure power source 5 is working, the siphon chamber 31 can be a closed chamber or a non-closed chamber. If the siphon chamber 31 is a non-closed chamber, for example, if the outlet end 22 of the siphon water distribution pipe 2 does not extend below the liquid surface of the degradation tank 7, then the negative pressure power source 5 needs to provide a larger suction force so that the sewage in the siphon chamber 31 is sucked into the suction end 21. However, generally speaking, the outlet end 22 of the siphon water distribution pipe 2 extends below the liquid surface of the degradation tank 7 so that the siphon water distribution pipe 2 has the effect of uniform water distribution.

[0040] In one embodiment, the suction end 41 is inserted into the siphon cloth pipe 2 and positioned downwards. This configuration ensures that when the negative pressure power source 5 activates instantaneously, drawing wastewater from the wastewater storage tank 11 of the siphon cloth pipe 2 into the degradation tank 7, the suction end 41, being located inside the siphon cloth pipe 2 and facing downwards, will not be flooded with wastewater, thus preventing contamination of the negative pressure power source 5. Furthermore, because the suction end 41 is located inside the siphon cloth pipe 2 and at a certain distance from the siphon cavity 31, the negative pressure power source 5 can be activated and immediately stopped, meaning its suction force can cease before the wastewater reaches the suction end 41, thereby better preventing wastewater from being accidentally drawn into the negative pressure power source 5.

[0041] In one embodiment, the electrically controlled negative pressure hydrolysis acidification tank water distribution device further includes a liquid level sensor 6, which is used to monitor whether the liquid level has reached the suction end 21. With this configuration, by monitoring the liquid level through the liquid level sensor 6, the power of the negative pressure power source 5 can be immediately stopped when liquid enters the siphon water distribution pipe 2, thereby enabling more precise control over the start and stop of the negative pressure power source 5.

[0042] In one embodiment, the liquid level sensor 6 is located outside the siphon chamber 31. When the liquid level in the sewage accumulation tank 11 submerges the liquid level sensor 6, the negative pressure power source 5 is triggered to operate until the liquid level in the sewage accumulation tank 11 is lower than the bottom of the siphon cover 3. In other embodiments, the liquid level sensor 6 is located inside the siphon chamber 31. When there is a large amount of liquid in the sewage accumulation tank 11, the liquid level in the siphon chamber 31 is forced to rise until it submerges the liquid level sensor 6. Then, the negative pressure power source 5 is triggered to operate until the liquid level in the sewage accumulation tank 11 is lower than the bottom of the siphon cover 3.

[0043] In one embodiment, a liquid level sensor 6 is disposed within the siphon cavity 31. Multiple liquid level sensors 6 are arranged sequentially along the height of the siphon water distribution pipe 2. This arrangement allows for the selection of a specific liquid level sensor 6 to trigger the negative pressure power source 5, thereby adjusting the pulse water flow. In other embodiments, the liquid level sensor 6 with the lowest horizontal height can serve as an element for monitoring the amount of sewage in the sewage storage tank 11, thus providing electrical control for replenishing sewage to the sewage storage tank 11.

[0044] In one embodiment, to achieve automated control, the electrically controlled negative pressure hydrolysis acidification tank water distribution device also includes a control system. Both the negative pressure power source 5 and the liquid level sensor 6 are electrically connected to the control system. During operation, when the liquid level sensor 6 detects that the liquid level has risen to a set height, it feeds a signal back to the negative pressure power source 5, which then activates, causing the air pressure in the siphon chamber 31 to decrease. This, in turn, raises the water level in the portion of the sewage in the sewage storage tank 11 above the siphon hood 3, until it reaches the suction end 21 of the siphon water distribution pipe 2, allowing it to be discharged into the degradation tank 7 along the siphon water distribution pipe 2. When the liquid level in the sewage storage tank 11 drops, causing the liquid level sensor 6 to detect a drop, the liquid level sensor 6 immediately feeds back to the control system, which then controls the negative pressure power source 5 to stop operating. Thus, this electrically controlled negative pressure hydrolysis acidification tank water distribution device realizes electrically controlled pulse water distribution. That is, as long as the liquid level of the sewage accumulation tank 11 reaches the bottom of the siphon hood 3, the conditions for starting the electrically controlled pulse have been met. As the liquid level of the sewage accumulation tank 11 is higher, the pulse water volume of the sewage accumulation tank 11 is greater.

[0045] In one embodiment, to prevent damage to the negative pressure power source 5, the negative pressure power source 5 is located outside the sewage storage tank 11. It is understood that the negative pressure power source 5 can also be located at the top of the sewage storage tank 11.

[0046] Among them, the negative pressure power source 5 is a Roots vacuum pump or a water ring vacuum pump.

[0047] In one embodiment, for ease of use, the electrically controlled negative pressure hydrolysis acidification tank water distribution device further includes a degradation tank 7, meaning the device itself has a built-in degradation tank 7, with the discharge end 42 extending into it. During initial use or periodic maintenance, the hydrolysis acidification process package can be placed in the degradation tank 7. This package contains various components such as pH adjusters, bacterial agents, and nutrients. Since this electrically controlled negative pressure hydrolysis acidification tank water distribution device operates on an electrically controlled pulse-type principle, the hydrolysis acidification process package is defined as a pulse hydrolysis acidification process package, abbreviated as HZHAP.

[0048] In one embodiment, the electrically controlled negative pressure hydrolysis acidification tank water distribution device further includes an inlet pipe 8, the outlet of which faces the sewage storage tank 11, and sewage is continuously or periodically discharged into the sewage storage tank 11 through the inlet pipe 8.

[0049] In one embodiment, the opening of the siphon hood 3 is set downwards, or the opening of the siphon hood 3 is set horizontally. It can be understood that when the opening of the siphon hood 3 is set horizontally, the momentary negative pressure generated inside the siphon hood 3 will not agitate the sewage at the bottom of the sewage accumulation tank 11. Therefore, the optimal method is to set the opening of the siphon hood 3 downwards, so that when a momentary negative pressure is generated inside the siphon hood 3, the sewage distribution is more uniform.
