Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a pulse device for anaerobic wastewater treatment tanks. Background Technology

[0002] In wastewater treatment processes, anaerobic tanks are commonly used treatment units, where anaerobic microorganisms decompose organic matter. A bell-type pulse distributor is a commonly used pulse device in anaerobic tanks.

[0003] Currently, commonly used bell-type pulse water distributors typically consist of a collection tank, an inlet, a fixed bell, and a central siphon pipe. Wastewater enters the collection tank through the inlet. When the water level in the collection tank rises from the lower end of the fixed bell to the upper end of the central siphon pipe, the wastewater begins to flow into the central siphon pipe, gradually carrying away the air above the fixed bell, thus creating a siphon effect. This causes the wastewater in the collection tank to quickly flow through the central siphon pipe into the wastewater pool below the bell-type pulse water distributor. When the water level in the collection tank drops back to the lower end of the fixed bell, air re-enters the fixed bell, the siphon effect is broken, and wastewater stops entering the central siphon pipe, completing one pulse water distribution cycle. The lower end of the fixed bell is the liquid level that breaks the siphon effect, also known as the siphon-breaking liquid level, while the upper end of the central siphon pipe is the liquid level that generates the siphon effect, also known as the siphon-generating liquid level.

[0004] However, because the position of the fixed bell in the bell-type pulse water distributor remains unchanged, the pulse water volume is a fixed value each time and cannot be adjusted. At the same time, the drainage pipe of the pulse device installed in the anaerobic tank is not effective at flushing sludge deposits at the bottom of the anaerobic tank. Therefore, there is an urgent need for a pulse device for wastewater treatment anaerobic tanks that can adjust the pulse water volume and effectively flush sludge deposits at the bottom of the anaerobic tank.

[0088] When it is necessary to reduce the pulse water volume, the telescopic end of the electric telescopic rod 203 moves upward, driving the reinforcing block 204 to move, so that the connecting column 232 connected to the connecting rod 205 moves upward together, thereby lifting the bell jar 231, thus reducing the distance between the lower end of the bell jar 231 and the upper end of the siphon tube 140, that is, reducing the distance between the siphon breaking liquid level and the siphon generating liquid level, thereby reducing the water volume of a single pulse drainage.

[0090] As one implementation method in this embodiment, refer to Figure 7 As shown, the guide tube section 300 includes:

[0091] Water pipe 310, which is connected to siphon pipe 140;

[0097] Among them, the side pipe body 322 of the outlet pipe fitting 320 expands the sewage discharge range, and the outlet pipe 323 is set at equal intervals, so that the sewage is evenly dispersed into the anaerobic tank, further enhancing the uniformity and comprehensiveness of sewage disturbance, improving the sludge deposition and flushing effect on the bottom of the anaerobic tank, and allowing more microorganisms in the anaerobic tank to fully contact the sewage, thereby improving the overall sewage treatment efficiency.

[0098] Working principle:

[0099] Wastewater is injected into tank 110 through inlet pipe 130. When the water level in the tank reaches the trigger height of siphon pipe 140, the siphon activation and bell frame 230 are observed, and the water flow status of guide pipe 300 is checked. According to the actual pulse water volume requirement, the distance between the lower end of bell 231 and the upper end of siphon pipe 140 is adjusted by electric telescopic rod 203, so that the distance between the siphon breaking liquid level and the siphon generation liquid level is adjusted, thereby allowing the water volume of a single pulse drainage to be adjusted according to actual needs. At the same time, the side pipe 322 of outlet pipe fitting 320 expands the wastewater discharge range, and the outlet pipe 323 is set at equal intervals, so that the wastewater is evenly dispersed in the anaerobic tank, further enhancing the uniformity and comprehensiveness of wastewater disturbance, improving the flushing effect on sludge sediment at the bottom of the anaerobic tank, and allowing more microorganisms in the anaerobic tank to fully contact the wastewater, thereby improving the overall wastewater treatment efficiency.
