Description

Technical Field

[0001] The utility model relates to the technical field of industrial wastewater treatment, in particular to an online disassembly-free cleaning device for a cyclone aerator. Background Art

[0002] The main component of the cyclone aerator is the cyclone, which generates centrifugal force through rotational motion. When the water flows through the cyclone, it is divided into an internal vortex and an external circulation. Under the action of the vortex, the oxygen in the water is forced to mix with the air, forming bubbles and dissolving into the water. The bubbles will rise in the axial direction of the cyclone and flow with the water. In this process, the bubbles bring oxygen above the water surface, thereby increasing the concentration of dissolved oxygen in the water. Since the bubbles produced by the cyclone aerator are very small, they can better contact with the microorganisms in the water, further increase the concentration of dissolved oxygen in the water, and promote the respiratory metabolism of aquatic organisms.

[0003] Due to the high hardness of industrial wastewater and the high content of calcium and magnesium ions, and the limitation of the operation cycle of the SBR pool, aeration and stirring are operated alternately, which gives the bottom activated sludge and calcium and magnesium ions time to attach and block the aerator outlet holes. At the same time, the cyclone aerator outlet holes are small, and the aerator outlet holes gradually shrink until they are blocked due to long-term accumulation. The air pressure provided by the fan alone cannot flush the outlet holes, causing the cyclone aerator outlet holes to be blocked, resulting in reduced oxygenation efficiency of the biochemical system, affecting the stable operation of the biochemical system, increasing the operating power consumption, and causing abnormal water outlet indicators of the biochemical system.

[0004] Therefore, the cyclone aerator needs to be cleaned regularly to ensure that the air outlet of the cyclone aerator remains unobstructed. The existing online cleaning method for the cyclone aerator is: limited by the layout of the aeration pipeline, to clean the blocked aerator, it is first necessary to set up a scaffolding, dismantle it online, and reinstall it after cleaning. The disadvantage is that the maintenance and cleaning procedures are long and the cost is high, and the aeration device cannot be operated with low consumption and high efficiency for a long period of time. At the same time, the workload of manual cleaning is large, and there is a risk of safety accidents when performing disassembly and inspection on the water surface. Utility Model Content

[0005] In view of the technical problem that cyclone aerators are difficult to clean due to blockage, the utility model aims to provide an online non-disassembly cleaning device for cyclone aerators, which can solve the problem of frequent scaling and blockage of cyclone aerators in biochemical devices for sewage treatment in industrial enterprises, realize online non-disassembly cleaning, and ensure stable and efficient operation of the aeration and oxygenation device of the biochemical system.

[0006] The utility model provides an online disassembly-free cleaning device for a cyclone aerator, comprising an aeration main pipe, one end of which is closed and the other end is connected to an aeration source, a plurality of aeration branch pipes are connected in parallel to the aeration main pipe, a detachable pipe cap is provided at the end of each aeration branch pipe, a valve A is provided on each aeration branch pipe, a plurality of aeration short pipes are connected in parallel to the aeration branch pipe between the pipe cap and the valve A, and the end of each aeration short pipe is connected to the air inlet end of the cyclone aerator.

[0007] Furthermore, a connecting short pipe with an external thread is welded at the end of each aeration branch pipe, and the pipe cap has an internal thread, and the connecting short pipe is threadedly connected to the pipe cap. The function is to facilitate further improvement on the existing pipeline layout to achieve the blocking of the end of the aeration branch pipe. Furthermore, the connecting short pipe is a DN50 steel pipe.

[0008] Furthermore, each aeration short pipe is provided with a valve B. Its function is to carry out targeted cleaning of the cyclone aerators. When a severely clogged cyclone aerator is to be cleaned, the corresponding valve B is opened, and the other valves B are closed to increase the flushing pressure. Alternatively, during online cleaning, the valve B corresponding to the cyclone aerator that is not clogged is closed to save water consumption and increase the flushing pressure of other cyclone aerators.

[0009] Furthermore, it also includes a pressurized water hose, when the pipe cap is removed from the end of the aeration branch pipe, the water outlet of the pressurized water hose is connected to the end of the aeration branch pipe. The outlet end of the pressurized water hose is arranged at the end of the aeration branch pipe, which is convenient for installation.

[0010] Furthermore, valve A and valve B are both solenoid valves, and the solenoid valves are electrically connected to the controller, thereby realizing automatic control of each valve.

[0011] The beneficial effect of the utility model is that the utility model utilizes the arrangement of the aeration main pipe and the aeration branch pipe so that the cyclone aerator has an array setting, realizes independent control of the cleaning of the cyclone aerator, and at the same time, a pipe cap for sealing is installed at the end of the aeration branch pipe. After removal, the cap is connected to the pressurized water pipe, and water enters from the air inlet end of the cyclone aerator to flush the inside of the cyclone aerator, and the blocked channels are flushed and cleaned thoroughly, ensuring that the air path of the aeration device is unobstructed, the oxygenation efficiency of the biochemical system is efficiently operated, the power consumption of the biochemical system is reduced, the water output index of the biochemical system is stabilized, the cleaning workload is reduced, and the safety accidents that are prone to occur in the existing scaffolding cleaning are avoided.
