Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to an aerator gas diversion device. Background Art

[0002] In MBR water treatment processes, the aeration methods for the lower portion of the MBR membrane unit are typically divided into three types: perforated tube aerators, trough aerators, and energy-saving pulse aerators. By blowing air from the bottom up, the curtain membrane is disturbed, thereby achieving better water purification. However, because the outlet of existing aerators is an upward-facing, exposed air port, the air from the port follows a random upward trajectory, resulting in an imbalance in the purge air volume on both sides of the curtain membrane. If operated in this unbalanced state for a long time, mud will accumulate more easily on the side with less purge air volume, reducing water purification effectiveness. Utility Model Content

[0003] In response to the above-mentioned deficiencies in the related prior art, the present application provides an aerator gas diversion device, which can make the movement trajectory of the gas more regular and evenly distribute the airflow, prevent mud accumulation, ensure water purification effect, and has strong practicality.

[0004] In order to achieve the above purpose, the utility model adopts the following technologies:

[0005] An aerator gas diversion device comprises an aeration box and a diversion box.

[0006] The top surface of the aeration box is provided with a plurality of aeration holes along its length direction; there are a plurality of diverter boxes, which are arranged in sequence along the length direction of the aeration box and aligned with the aeration holes. The upper end of the diverter box is opened and provided with a baffle, which is located on the central plane of the diverter box. A plurality of diverter plates are evenly arranged in the diverter box along the circumferential direction. The number of diverter plates is an even number and is evenly distributed on both sides of the baffle.

[0007] Furthermore, a through hole is provided at the center of the bottom of the diversion box, and a connecting pipe is provided at the lower end of the through hole, and the connecting pipe is passed through the aeration hole.

[0008] Furthermore, the diverter plate is arc-shaped and its inclination directions are all in the same direction. One end of the diverter plate is connected to the side wall of the diverter box, and the other end is flush with the side wall of the through hole.

[0009] Furthermore, a slot is provided on the top of the diversion box, and the lower end of the baffle is fitted into the slot.

[0010] The beneficial effects of the utility model are as follows: by arranging a plurality of diverter plates around the aeration holes, the gas is diverted, and a baffle is arranged at the upper end of the aeration box, so that the diverted gas is evenly distributed on both sides of the baffle, thereby making the movement trajectory of the gas more regular, which is beneficial to the purge of the curtain membrane, ensuring the water purification effect, and also preventing mud accumulation, saving cleaning costs; and it can effectively reduce the purge gas volume and reduce costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present invention.

[0013] Figure 2 This is a front view of the aeration box according to an embodiment of the present application. DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0015] like Figure 1-Figure 2 As shown, this example provides an aerator gas diversion device, including: an aeration box 100 and a diversion box 200.

[0016] The top surface of the aeration box 100 is provided with a plurality of aeration holes 101 along its length, and aeration is introduced into the sewage through the aeration holes 101; there are multiple diverter boxes 200, which are arranged in sequence along the length of the aeration box 100 and aligned with the aeration holes 101. The upper end of the diverter box 200 is opened and provided with a baffle 201. The baffle 201 is located on the central plane of the diverter box 200. A plurality of diverter plates 202 are evenly spaced along the circumferential direction in the diverter box 200. The number of diverter plates 202 is even and evenly distributed on both sides of the baffle 201 to guide and divert the airflow coming out of the aeration holes 101 so that it is evenly distributed on both sides of the baffle 201, ensuring that the airflow evenly sweeps the curtain membrane.

[0017] Specifically, a through hole 203 is provided at the bottom center of the diverter box 200, and a connecting pipe 204 is provided at the lower end of the through hole 203. The connecting pipe 204 is passed through the aeration hole 101, so that the air flow coming out of the aeration hole 101 can first pass through the diverter box 200, and then blow the curtain membrane after being diverted by the diverter box 200.

[0018] Specifically, the diverter plate 202 is arc-shaped and its inclination direction is in the same direction, for example, clockwise or counterclockwise. One end of the diverter plate 202 is connected to the side wall of the diverter box 200, and the other end is flush with the side wall of the through hole 203, thereby dividing the diverter box 200 into several identical areas, thereby realizing the diversion of the aeration airflow.

[0019] Specifically, a slot is provided on the top of the diverter box 200 , and the lower end of the baffle 201 fits in the slot, thereby facilitating the disassembly and installation of the baffle 201 .

[0020] Since the above are only preferred embodiments of the present invention and are not intended to limit the present invention, it is obvious that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Therefore, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
