Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of anti-deposition devices, specifically, to an anti-deposition device for sludge in a sewage collection tank. Background Technology
[0002] SCR denitrification catalysts deactivate after approximately 24,000 hours of operation. One factor contributing to this deactivation is the blockage of the catalyst pores by fly ash. During the regeneration process, spent denitrification catalysts require removal of this ash through ultrasonic and chemical cleaning. Consequently, the wastewater generated during the cleaning process contains a significant amount of ash. This wastewater, transported to the sewage collection tank via pipelines, easily accumulates at the pipe inlet, making it difficult for the aeration devices to open. Because the ash is similar in nature to mud and sand, it settles quickly and easily clumps together. Once deposited, it is difficult to loosen, reducing tank volume and making cleaning challenging.
[0003] Currently, wastewater collection ponds for spent denitrification catalysts mostly use blower aeration devices to prevent sludge deposition, but the effect is not ideal. The aeration heads are prone to clogging, and ash accumulates in the gaps. After a period of operation, manual cleaning is required, which is time-consuming and labor-intensive, affecting production. Therefore, there is an urgent need for a device to solve the above-mentioned technical problems. Utility Model Content
