Description

Technical Field

[0001] This utility model relates to the field of hydrochloric acid wastewater conditioning technology, specifically a hydrochloric acid wastewater conditioning and reuse device. Background Technology

[0002] Hydrochloric acid is a widely used chemical reagent in industrial production, with extensive applications in metal processing, chemical synthesis, and pharmaceuticals. The hydrochloric acid wastewater produced after its use is highly acidic. If discharged directly without treatment, it will not only corrode drainage pipes but also cause serious pollution to the natural environment, such as soil and water bodies, disrupting the ecological balance. Furthermore, it violates environmental regulations and faces hefty penalties. Therefore, the effective treatment and reuse of hydrochloric acid wastewater, transforming it into water resources that meet emission standards or are reusable, is of great significance for achieving sustainable industrial development and protecting the ecological environment.

[0003] However, traditional hydrochloric acid wastewater treatment technologies have shortcomings. Some treatment equipment uses a single neutralization reaction method, adjusting the pH value only by adding alkaline substances, which is insufficient to remove solid impurities and colloidal pollutants from the wastewater. The treated water quality cannot meet the requirements for reuse. In addition, some traditional equipment has a complex structure, occupies a large area, has high installation and maintenance costs, and has poor stability during operation, easily leading to problems such as leakage and blockage, resulting in low treatment efficiency. These defects not only increase the wastewater treatment costs of some enterprises, but also limit the resource utilization of hydrochloric acid wastewater. Therefore, we propose a hydrochloric acid wastewater conditioning and reuse equipment. Utility Model Content

[0024] Working Principle: Wastewater containing hydrochloric acid is first connected to the equipment through a flange at the top of the inlet pipe 1. The flange facilitates quick connection to external pipes, ensuring a stable wastewater input. The wastewater flows along the inlet pipe 1 into a wastewater tank 14 at its bottom. The wastewater tank 14 serves as a temporary storage space, holding a certain amount of wastewater to allow time for subsequent treatment. Multiple equidistant filter cartridge placement slots 15 are distributed between the wastewater tank 14 and the reclaimed water tank 18. The filter cartridges 3 housed inside form the core treatment unit. Both ends of the filter cartridges 3 extend to the wastewater tank 14 and the reclaimed water tank 18, respectively. The waterproof ring 13 at the left end of the filter cartridge 3 tightly fits against the left end face of the wastewater tank 14, forming a seal to prevent leakage. After entering the wastewater tank 14, the wastewater is initially intercepted by the coarse filter screen 4 at the left end of the filter cartridge 3. The coarse filter screen 4 filters out large solid particles, achieving preliminary purification. The pre-filtered wastewater continues to flow through the neutralization layer 5, which is filled with an appropriate amount of neutralizing agent, such as calcium carbonate or other alkaline substances. The wastewater can neutralize hydrochloric acid, adjusting its pH to near neutral. The neutralized wastewater then undergoes secondary filtration through a precision filter screen 6. The precision filter screen 6 has extremely small pores, filtering out tiny particles, colloids, and other impurities, further improving water quality. To ensure stable operation of the filter cartridge 3, the fixing components play a crucial role. The clamping plate arc 11 is semi-circular and fits against the cylindrical surface of the filter cartridge 3. The top telescopic rod 9 passes through the telescopic fixing hole 17 on the support plate 16 and is fitted with a compression spring 10. When the threaded post at the bottom of the fixing rod 12 is tightened, the clamping plate arc 11, under the elastic force of the compression spring 10, firmly fixes the filter cartridge 3, preventing it from shaking or shifting under the impact of wastewater. The purified wastewater flows into the recycling tank 18 through the right end of the filter cartridge 3. The cover plate 8 hinged at the top of the recycling tank 18 can be opened as needed for easy inspection of water quality or cleaning and maintenance. The purified water is discharged through the outlet pipe 7, realizing the adjustment and reuse of hydrochloric acid wastewater.
