Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of IC anaerobic tank water distribution devices. BACKGROUND

[0002] In the sewage treatment industry, when the influent organic pollutant concentration of sewage station is higher, anaerobic bioreactor is usually set to treat. Among them, IC anaerobic reactor is widely used due to its excellent treatment effect and the advantage of producing available biogas. The influent of IC anaerobic reactor is usually equipped with influent water distribution device, which aims to distribute the influent to all parts of the tank bottom, achieving uniform water distribution effect. At the same time, IC anaerobic tank also needs to set up an external circulation system, which uses an external circulation pump to extract wastewater from the upper part of the tank and hits the tank bottom to form a cycle. In order to evenly distribute the circulating water entering the bottom of the tank, a water distribution device also needs to be set up.

[0003] The usual practice of prior art is to set two sets of water distribution devices for two influents. The main disadvantage of this method is to increase the land occupation and material consumption. On the other hand, when using the same water distribution device, the two streams of water will interfere with each other, and adjusting the flow of one stream of water will cause the flow of the other stream of water to change, thereby affecting the stable operation of the anaerobic tank. For example, the Chinese utility model with authorization announcement No. CN212476281U discloses "a new anaerobic reactor". According to the description in paragraph

[0034] of the specification: the raw water is measured by raw water flow meter and then enters the anaerobic tank, and is mixed with the water input by the external circulation pipe.

[0004] The Chinese utility model with authorization announcement No. CN220537602U discloses "an improved anaerobic reactor". Although this patent distributes raw water and circulating water separately, it does not set up a water distribution device (water distribution bag, buffer tank) in the raw water inlet section, which is easy to cause water flow impact on the sludge bed inside the anaerobic tank, which is not conducive to maintaining stable hydraulic conditions in the anaerobic tank. At the same time, the raw water enters the anaerobic tank without uniform water distribution, which cannot ensure that the water quality in each area of the anaerobic tank bottom is uniform and consistent, and cannot fully mix with the external circulation water entering the anaerobic tank.

[0005] The technical problem to be solved by the utility model provides a kind of IC anaerobic tank water distribution device, which simultaneously collects raw water and circulating water, and the two streams of water do not interfere with each other in the water distributor chamber. It also achieves the purpose of saving installation space and balancing the influent.

[0006] The technical solution of the utility model is as follows:

[0007] The application discloses an IC anaerobic tank water distribution device, which comprises an outer cylinder, a raw water inlet pipe connected to one end of the outer cylinder, a plurality of raw water distribution branch pipes connected to the lateral wall of the outer cylinder, and an inner cylinder fixedly installed in the inner cylinder; the inner end of the raw water inlet pipe and the inner end of the raw water distribution branch pipes are communicated with a chamber between the outer cylinder and the inner cylinder; one end of the inner cylinder is connected with a circulating water inlet pipe, the circulating water inlet pipe is led out from the end of the outer cylinder, and the outer end of the circulating water inlet pipe is used for connecting a circulating water inlet pipe; a plurality of circulating water distribution branch pipes are connected to the lateral wall of the inner cylinder, the inner end of the circulating water distribution branch pipes is communicated with the inner cylinder, and the circulating water distribution branch pipes are led out from the lateral wall of the outer cylinder and communicated with an inner tank bottom water distribution pipeline of the IC anaerobic tank through a pipeline.

[0008] Preferably, the outer cylinder is further connected with a drain pipe for draining water in the water distribution device; the inner end of the drain pipe is connected with the chamber between the outer cylinder and the inner cylinder, and the outer end of the drain pipe is connected with a drain pipeline.

[0009] Preferably, the outer wall of the inner cylinder is fixedly connected with the inner wall of the outer cylinder through a support.

[0010] Preferably, the bottom end of the outer cylinder is provided with a supporting leg as a supporting mechanism of the water distribution device.

[0011] Compared with the prior art, the application has the following beneficial effects:

[0012] The device is provided with an inner sleeve chamber in the original water distributor chamber, raw water is dispersed into the anaerobic tank through the outer chamber, and circulating water is dispersed into the anaerobic tank through the inner chamber, so that the two water flows are separated and do not interfere with each other, and the stable operation of the anaerobic tank is ensured. After being provided with the water distribution device, the raw water and the circulating water of the anaerobic tank are distributed through the same water distribution device, the two water flows do not interfere with each other and do not form convection, so that water head loss and flow loss caused by convection are avoided. When a single water flow is adjusted, the other water flow is not affected, and the operation stability of the anaerobic tank is improved. On the other hand, after being provided with the water distribution device, the raw water and the circulating water of the anaerobic tank are distributed through the same water distribution device, and the occupied space and the consumables of the water distribution device are reduced.
