With the increasing awareness of environmental protection, chemical plant exhaust treatment has become the focus of attention in the industry. As an efficient and environmentally friendly waste gas treatment technology, biological deodorization has been widely used in chemical plants. In the biological deodorization process, lye spraying is a crucial part. In this article, we will introduce you to the chemical plant waste gas bio-deodorization process and discuss in depth why the submerged pump outside the tank is ideal for lye spraying.
Chemical plant waste gas biological deodorization process is a technology that uses microorganisms to degrade pollutants in organic waste gas. It makes microorganisms grow and multiply in a suitable environment by spraying biological bacterial agents in the exhaust gas treatment system, and then transforms harmful substances in the exhaust gas into harmless substances. Biological deodorization technology has the advantages of high efficiency, environmental protection, economy and so on, and plays an important role in chemical plant exhaust gas treatment.
Lye spraying, as the key link of biological deodorization process, is mainly to adjust the pH value of waste gas by spraying lye uniformly in the waste gas to provide a suitable living environment for microorganisms. At the same time, lye can also be neutralized with the acidic substances in the waste gas, reduce the corrosiveness of the waste gas, to protect the waste gas treatment equipment from damage.
In the process of lye spraying, it is crucial to choose a suitable pump to transport lye. With its unique advantages, the submerged tank pump has become the ideal choice for lye spraying. The following are the characteristics and roles of extra-tank submerged pumps in lye biological deodorization treatment:
Anti-corrosion and corrosion resistance, strong adaptability
The extra-tank submerged pump is usually made of engineering plastics such as GFRPP, PVDF, etc., which has excellent anticorrosion and corrosion resistance. It is able to resist the erosion of strong acid, alkali and other corrosive liquids, ensuring the stable operation of the pump in the process of lye spraying. At the same time, this material also makes the extra-tank submerged pump able to adapt to most corrosive liquid media, with a wide range of uses.
High mechanical strength and efficiency
The submerged pump adopts a new impeller design with one-piece molding, which has high mechanical strength and can withstand high pressure and load. This design enables the pump to maintain a high flow rate and flow rate when conveying lye, which improves the spraying effect. At the same time, the new impeller also has high efficiency, which can reduce energy consumption and lower operating costs.
Reduced leakage points and tighter
The extra-tank submerged pump mostly adopts one-piece molding pump body design, which reduces the leakage points at the connection. This design makes the pump tighter during operation and reduces the risk of leakage. During the lye spraying process, this tight pump body structure ensures that lye will not leak into the external environment, protecting the environment and the safety of employees.
Strong kinetic energy, high efficiency and energy saving
The submerged pumps are equipped with motors of well-known brands such as TECO and Takasaki, which have strong kinetic energy and can meet the actual needs of most working conditions. At the same time, these motors are also characterized by high efficiency and energy saving, which can reduce energy consumption and operating costs. In the process of lye spraying, the strong kinetic power and high efficiency and energy saving make the submerged pump outside the tank an ideal choice.
No leakage, small footprint, easy to operate
The extra-tank submerged pump is connected to the liquid during operation, and under normal conditions there is no leakage. This design allows the pump to maintain a clean, dry operating environment during the lye spraying process, reducing maintenance costs. At the same time, the extra-tank submerged pump covers a small area, is simple to operate, and is convenient for overhaul and maintenance. These features make the tank outside the submerged pump in the chemical plant waste gas biological deodorization process has been widely used.
Diverse forms, wide range of applications
External submerged tank pumps have a variety of innovative appearance and form, can meet the needs of different and complex working conditions. Whether it is a large chemical plant or a small waste gas treatment plant, the submerged tank pump can provide the appropriate pump type and configuration. This wide range of applicability makes the submerged tank pump in the field of waste gas treatment has a broad market prospects.
In summary, with its anti-corrosion and corrosion resistance, high mechanical strength, reduced leakage points, strong kinetic energy, no leakage phenomenon, and a variety of forms, etc., the external submerged tank pump plays an important role in the chemical plant waste gas biological deodorization process. Selecting the submerged pump outside the tank as the pump type of lye spray can not only improve the effect of waste gas treatment but also reduce energy consumption and operating costs. Therefore, it is wise to choose the submerged pump in the chemical plant waste gas treatment project.
