Description

Technical Field

[0001] This invention relates to the field of industrial water treatment technology, specifically to a jet-separation type mixing and dosing device. Background Technology

[0002] Industrial water treatment refers to the process of treating water used in industrial production to meet production quality standards. This process encompasses multiple aspects, including physical, chemical, and biological treatment, aiming to ensure product quality, improve production efficiency, protect equipment safety, and reduce environmental pollution. Specific methods of industrial water treatment include the following:

[0003] ① Physical methods: These mainly include sedimentation, filtration, adsorption, and centrifugation. These methods remove suspended solids and impurities from water through physical action. They have the advantages of simple operation and low cost, but the treatment effect is limited, and they are generally used as pretreatment methods.

[0004] ② Chemical methods: These methods involve adding chemical agents to react with impurities in the water, thereby removing them. Commonly used chemical methods include coagulation, sedimentation, oxidation-reduction, and neutralization. Chemical methods are effective but costly and may introduce new chemical substances.

[0005] ③ Biological methods: These methods utilize the metabolic processes of microorganisms to convert organic matter in water into harmless substances. Commonly used biological methods include activated sludge processes and biofilm processes. Biological methods offer good treatment results and lower costs, but they require high-quality water and have a longer treatment time.

[0006] ④ Membrane separation technology: A novel water treatment technology, mainly including reverse osmosis, nanofiltration, and ultrafiltration. Membrane separation technology has advantages such as high efficiency, energy saving, and environmental friendliness, but the membrane has a relatively short lifespan and needs to be replaced regularly.

[0007] In industrial water treatment equipment, chemical dosing devices are frequently used. The main function of these devices is to inject liquid chemicals into the pipeline using a pulse pump, with the two processes achieved through a chemical mixer. Common chemical mixers often have enlarged inlet and outlet diameters, making them relatively bulky and inconvenient to operate. In confined installation environments, this can lead to insufficient installation distance.

[0008] Therefore, how to design a small and easy-to-install dosing device, achieve low dosing resistance and easy disassembly and maintenance, and improve water treatment efficiency is a technical problem that urgently needs to be solved. Summary of the Invention

[0014] More preferably, one end of the transverse reinforcing rib is welded to the outer wall of the dosing tube, and the other end of the transverse reinforcing rib is provided with a gap between it and the inner wall of the vertical tube. One side of the lower side of the transverse reinforcing rib is welded to the inner wall of the vertical tube.

[0015] More preferably, the upper end face of the vertical reinforcing rib is welded to the center position of the lower end face of the horizontal reinforcing rib, and the lower end face of the vertical reinforcing rib is located at the connection between the dosing elbow and the dosing nozzle.

[0016] Preferably, the dosing nozzle has a plurality of spray holes evenly arranged thereon.

[0017] Preferably, the second blind flange, the first blind flange, the transverse reinforcing rib, the vertical reinforcing rib, the dosing nozzle, and the dosing elbow are integrally formed structural components, and the transverse projection length of the integrally formed structural component is less than the inner diameter of the vertical straight pipe.
