Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to an online cleaning and descaling device for corundum aerators and a biochemical tank. Background Technology

[0002] Industrial wastewater treatment plants typically produce high-hardness wastewater, making it prone to scaling on the surface of corundum microporous aerators used in biological treatment tanks. This scaling is exacerbated by environmental regulations that require the installation of deodorizing sealing covers in these tanks, leading to significantly higher water temperatures in summer. This further accelerates scaling on the aerator surface, causing micropore blockage, increasing blower pressure, and resulting in frequent blower surges and shutdowns. This severely impacts the normal operation of the biological treatment tank and related equipment. Currently, the most common solution is to manually disassemble each aerator and then soak and clean them in formic acid.

[0003] Problems and shortcomings of existing technologies:

[0004] The operation is time-consuming and labor-intensive, with high cleaning costs and low efficiency. Furthermore, the operation can affect the normal operation of the biological treatment tank. Utility Model Content

[0018] Figure 2 This is a partially enlarged connection diagram of the aeration main pipe of this utility model. Detailed Implementation

[0019] like Figure 1 As shown, this utility model discloses an online cleaning and descaling device 9 for corundum aerators, a formic acid dosing device 1, and a dosing hose 2. The formic acid dosing device 1 is equipped with the dosing hose 2, and the end of the dosing hose 2 is equipped with a quick connector 4. The dosing hose 2 is connected to the aeration main pipe 5 of the biological treatment tank through the quick connector 4. This online cleaning and descaling device for corundum aerators is powered by an external power supply YJV4*2+1mm. 2 8. The formic acid in the formic acid dosing device enters the corundum aerator 6 through the dosing hose 2, quick connector 4, and aeration main pipe 5 in sequence, gradually dissolving and removing the scale in the corundum aerator 6 from the inside out.

[0020] The online cleaning and descaling device for corundum aerators of this utility model also includes a movable wheel 3. The movable wheel 3 is installed at the bottom of the formic acid dosing device 1, and the number of movable wheels 3 is at least two.

[0021] The quick connector 4 of the online cleaning and descaling device for corundum aerators of this utility model is detachable. When in use, one end of the quick connector 4 is installed at the end of the dosing hose 2, and the other end of the quick connector 4 is installed on the aeration main pipe 5.

[0022] like Figure 2As shown, the aeration main pipe 5 is provided with a through hole, and an internal threaded connector 9 is welded at the through hole position. A nozzle 11 is installed on the internal threaded connector 9. One end of the nozzle 11 is connected to the quick connector 4, and the other end of the nozzle 11 is inserted into the internal threaded connector 9 and extends into the interior of the aeration main pipe 5.

[0023] The online cleaning and descaling device for corundum aerators of this utility model also includes an aeration main pipe 5, which is connected to the dosing hose 2.

[0024] The working principle of this utility model:

[0025] This utility model discloses an online cleaning and descaling device for corundum aerators. Each aeration main pipe 5 is equipped with an internal threaded connector 9 (dosing interface) and a stainless steel nozzle. In use, the quick connector 4 at the end of the formic acid dosing hose 2 is installed on the stainless steel nozzle. Utilizing the volatility of formic acid and the ability to operate without interruption, the air generated by the blower propels the formic acid sequentially through the dosing hose 2, the stainless steel nozzle, and the aeration main pipe 5 before delivering it to the inner wall of each corundum aerator 6. This process gradually dissolves and removes the scale within the corundum aerator 6 from the inside out.
