Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a water distribution device of an IC anaerobic reactor. Background Art

[0002] IC anaerobic reactors are widely used in the treatment of high-concentration organic wastewater. They can significantly reduce the COD in wastewater and reduce the operating costs of wastewater treatment. The water distribution device is one of the key components for the efficient operation of IC anaerobic reactors. It can make the wastewater and sludge entering the reactor evenly mixed and fully contacted, improve the mass transfer efficiency, and thus improve the treatment effect of wastewater. Traditional water distribution devices include branch-shaped water distribution and multi-point water distribution. They have the disadvantages of uneven water distribution, easy hardening and scaling of sludge to block the water distribution device, and difficult cleaning after blockage. For this reason, we propose a water distribution device for IC anaerobic reactors. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a water distribution device for an IC anaerobic reactor, which solves the problems raised in the above background technology.

[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: a water distribution device for an IC anaerobic reactor, comprising an IC anaerobic reactor tank body, a plurality of water distribution branch pipes are fixedly connected to the inside of the IC anaerobic reactor tank body, the plurality of water distribution branch pipes extend to the outside of the IC anaerobic reactor tank body and are fixedly connected to a water distribution mother pipe, a first guide plate is fixedly connected to the inside of the IC anaerobic reactor tank body, a second guide plate is fixedly connected to the inside of the IC anaerobic reactor tank body, a plurality of gas-liquid separation tanks are fixedly connected to the top of the IC anaerobic reactor tank body, a downcomer is fixedly connected to the inside of the gas-liquid separation tank, the downcomer extends to the inside of the IC anaerobic reactor tank body and is located between the first guide plate and the second guide plate, a plurality of mud discharge branch pipes are fixedly connected to the inside of the IC anaerobic reactor tank body, the plurality of mud discharge branch pipes extend to the outside of the IC anaerobic reactor tank body and are fixedly connected to a mud discharge mother pipe.

[0005] Preferably, the first guide plate and the second guide plate cooperate with each other.

[0006] Preferably, a jacketed pipe is fixedly installed on the outer side of the water distribution branch pipe, a pinch valve is fixedly connected to the outer side of the jacketed pipe, and a branch valve is fixedly connected to the outer side of the water distribution branch pipe. Through the cooperation of the water distribution branch pipe, the branch valve, the jacketed pipe and the pinch valve, when a water distribution branch pipe is blocked, the pipe can be drawn out for cleaning without stopping the water supply, and closing the pinch valve will not affect the operation of other water distribution branch pipes.

[0007] Preferably, a mud discharge valve is fixedly installed on the outer side of the mud discharge branch pipe.

[0008] Preferably, the water distribution branch pipe has a specification of DN65-DN100, is inserted into the reactor at an angle of 30°-60°, and has an insertion depth of 400-1500mm. The caliber of the water distribution branch pipe is much larger than the aperture or gap of the traditional water distribution, so it is not easy to be calcified and blocked.

[0009] Preferably, the first guide plate is an inverted hollow cone. Through the inverted hollow cone-shaped first guide plate, when the wastewater flows to the bottom of the reactor, the radius is smaller and the flow rate is greater the closer to the bottom of the reactor, so that the wastewater forms a vortex, the water is evenly distributed, and the wastewater and granular sludge are fully mixed.

[0010] Preferably, the second guide plate is in the shape of a right cone, and the second guide plate in the shape of a right cone can prevent sludge deposition caused by too low wastewater flow rate in the central area at the bottom of the reactor.

[0011] The utility model provides a water distribution device for an IC anaerobic reactor, which has the following beneficial effects:

[0012] 1. The water distribution device of the IC anaerobic reactor can form a vortex through the first guide plate to make the water distribution uniform after the wastewater is sprayed into the interior of the IC anaerobic reactor tank through the water distribution branch pipe, and the wastewater is fully mixed with the granular sludge. In addition, through the cooperation of the branch valve, the jacket pipe and the pinch valve, when a water distribution branch pipe is blocked, closing the valve at the water distribution branch pipe will not affect the operation of other water distribution branches, which is convenient for cleaning the blocked water distribution branch pipe. The water distribution branch pipe has a large diameter, which is much larger than the aperture or gap of the traditional water distribution, so it is not easy to be calcified and blocked, thereby improving the service life of the water distribution branch pipe and the applicability of the water distribution device of the IC anaerobic reactor.

[0013] 2. The water distribution device of the IC anaerobic reactor can form disturbance in the area between the two guide plates through the cooperation of the second guide plate, the gas-liquid separation tank, the downcomer, the sludge discharge branch pipe, and the sludge discharge main pipe to avoid sludge deposition. Correspondingly, a sludge discharge branch pipe is set in this area to discharge dead sludge regularly to prevent sludge hardening and scaling, which can alleviate blockage.

[0021] The first guide plate 31 and the second guide plate 32 cooperate with each other; the first guide plate 31 is an inverted hollow cone, and the first guide plate 31 of the inverted hollow cone makes the wastewater flow to the bottom of the reactor. The closer to the bottom of the reactor, the smaller the radius and the greater the flow rate, so that the wastewater forms a vortex, the water distribution is uniform, and the wastewater and the granular sludge are fully mixed. The second guide plate 32 is a right cone, and the right cone-shaped second guide plate 32 can prevent the wastewater flow rate in the center area of ​​the bottom of the reactor from being too low, resulting in sludge deposition;

[0022] A jacketed pipe 24 is fixedly installed on the outside of the water distribution branch pipe 22, a pinch valve 25 is fixedly connected to the outside of the jacketed pipe 24, and a branch valve 23 is fixedly connected to the outside of the water distribution branch pipe 22. Through the cooperation of the water distribution branch pipe 22, the branch valve 23, the jacketed pipe 24 and the pinch valve 25, when a certain water distribution branch pipe 22 is blocked, the pipe can be drawn out for cleaning without stopping the water supply, and closing the pinch valve 25 will not affect the operation of other water distribution branch pipes 22. The specifications of the water distribution branch pipe 22 are DN65-DN100, and it is inserted into the reactor at an angle of 30°-60°, and the insertion depth is 400-1500mm. The caliber of the water distribution branch pipe 22 is much larger than the aperture or gap of the traditional water distribution, so it is not easy to be calcified and blocked;

[0023] A mud discharge valve 52 is fixedly installed on the outer side of the mud discharge branch pipe 51 .

[0024] In summary, when the water distribution device of the IC anaerobic reactor is used, the staff first discharges the wastewater into the water distribution mother pipe 21, and then sprays the wastewater into the surface of the first guide plate 31 inside the IC anaerobic reactor tank 1 through the water distribution branch pipes 22 evenly arranged on the outer wall of the IC anaerobic reactor tank 1. The first guide plate 31 forms an inverted truncated cone shape. The closer to the bottom of the reactor, the smaller the radius and the greater the flow rate, so that the wastewater forms a vortex, the water distribution is uniform, and the wastewater is fully mixed with the granular sludge. Then, the wastewater passes through the second guide plate 32 set in the center of the IC anaerobic reactor tank 1. The second guide plate 32 forms a right cone, which can prevent the wastewater flow rate in the central area of ​​the IC anaerobic reactor tank 1 from being too low to cause sludge deposition. At the same time, multiple gas-liquid separation tanks 41 are started, and the area between the first guide plate 31 and the second guide plate 32 is disturbed by the downcomer 42 to avoid sludge deposition. At the same time, a sludge discharge branch pipe 51 is set through the area to regularly discharge dead sludge to prevent sludge hardening and scaling, which can alleviate the blockage. If a water distribution branch pipe 22 is blocked, the corresponding clamping valve 25 is closed to facilitate the extraction and cleaning of the water distribution branch pipe 22.
