Detailed application of vertical long axis suspended semi submersible sump pump in medium transportation of neutralization pretreatment unit

The vertical long axis suspended semi submersible sump pump, with its core characteristics of strong acid and alkali corrosion resistance, no leakage, and stable operation, has become the mainstream transportation selection for the neutralization pretreatment unit medium transportation scenario. It fully adapts to the complex and changing medium transportation needs of the neutralization pretreatment unit. The specific application details are as follows:
Core Transport Scenario of Neutralization Preprocessing Unit
·Acidic wastewater lifting and transportation: Strong acidic wastewater from front-end acid washing, chemical and other processes is steadily lifted and transported from the collection tank to the neutralization reaction tank, providing continuous and stable inflow flow for the neutralization reaction.
·Accurate feeding and transportation of alkaline agents: Transport neutralizing alkaline agents such as caustic soda and lime milk, accurately feed the agents into the neutralization reaction tank, and adapt to the strong corrosion conditions of high concentration alkaline agents.
·Transport of solid containing wastewater after neutralization: Transport the highly suspended wastewater containing a large amount of metal hydroxide precipitation generated after neutralization reaction to the subsequent coagulation and sedimentation process.
·Emergency waste liquid transfer: As an emergency backup pump for the neutralization unit, it can quickly transfer abnormal acidic and alkaline waste liquids in the reaction tank, avoiding the risk of medium overflow caused by uncontrolled neutralization reactions.
✅  Core advantages of scene specific adaptation
·Full pH range corrosion resistance: The overcurrent components can be made of materials such as fluoroplastics and 316L stainless steel, which can withstand the corrosion of strong acidic and alkaline media at the same time, and are suitable for the working conditions where the pH value of the neutralization unit medium fluctuates greatly.
·Leak free safety guarantee: With no exposed mechanical seal design, it prevents the leakage of acidic and alkaline media from the root, avoids the volatilization and diffusion of corrosive agents, and ensures the safety of the working environment in the neutralization workshop.
·Strong anti blocking ability: The open large channel impeller design can smoothly pass through the metal hydroxide floc precipitation generated by neutralization reaction, and is not prone to jamming and blockage, suitable for the transportation needs of high suspended solids and wastewater.
·Stable operation and easy maintenance: The vertical structure is directly installed on the top of the pool, occupying a small area. The rotor can be extracted and the maintenance can be completed without disassembling the pipeline, greatly reducing the difficulty of maintenance under high corrosion conditions.
Key points for scene specific selection
·When transporting alkaline and high solid media such as high concentration lime milk, high chromium wear-resistant alloy overcurrent components should be preferred to avoid rapid particle wear on the impeller.
·When the medium contains a large amount of metal hydroxide precipitation particles, the guide bearing must be equipped with an external clean cooling water lubrication system, and a hard alloy shaft sleeve should be selected to avoid particle wear and bearing failure.
·Equipped with a variable frequency regulation system, the conveying flow can be dynamically adjusted in real-time according to the pH value of the neutralization tank, achieving precise dosing control and improving the treatment efficiency of the neutralization reaction.
At present, the vertical long axis suspended semi submersible sump pump, which is suitable for the medium transportation scenario of neutralization and pretreatment units, has a mainstream flow rate coverage of 5-500 m ³/h and a head of 10-60 m. There are already a large number of mature landing cases of vertical long axis suspended semi submersible sump pumps in the chemical and metallurgical acid washing wastewater treatment industries, fully meeting the strict requirements for medium transportation in neutralization and pretreatment units.
