1. The important value of centrifuges in chemical production
As one of the indispensable key equipment in the chemical industry, the basic principle of centrifuges is to use centrifugal fields to separate and process mixed materials. Centrifuges play a very important role in chemical production. Its use significantly reduces the difficulty of operation and frees the hands of workers. They only need to press a few operating buttons to achieve the purpose of centrifugation, and centrifuges can work day and night. When the material is placed in a high-speed rotating centrifuge, due to the differences in mass, density, size or shape of different components, they will move in different directions under the action of centrifugal force, thereby achieving the purpose of separation or purification.
There are many types of centrifuges, including but not limited to three-legged centrifuges, scraper centrifuges, horizontal screw centrifuges and disc centrifuges, each type has its specific application scenarios and advantages. In order to reasonably protect the machine, a spare centrifuge can be installed to let it rest when the heat level of a machine is more serious, and the maintenance cost of the machine can be reduced without affecting the production progress. Centrifuges can also separate fluids of different viscosities, with a wide range of effects, which can produce greater economic benefits.
2. Structure and working process of centrifuge
The horizontal spiral unloading sedimentation centrifuge, commonly used in the chemical industry, comprises 13 devices, including a drum, a motor, a motor drive, and a spiral pusher. It operates by introducing the suspension into the drum through the spiral discharge port, where the high-speed rotation produces a significant centrifugal force. Heavy and dense solid particles adhere to the inner wall of the drum under the influence of the gravity field, and are later processed and discharged through the slag discharge port by the spiral blades. The resulting clear liquid flows out through the drum outlet. The movement of the drum and spiral is primarily controlled by the auxiliary motor, with the difference in speed between the two being achieved through the differential in the system.
The main motor affects the differential’s operation through the drum’s action, while the coupling plays an essential role in controlling the input shaft’s speed. Through the speed ratio of rotation, the differential imparts force to the spiral, ultimately achieving the purpose of separating materials and other Achieve efficient separation of solid and liquid materials with the horizontal spiral unloading sedimentation centrifuge. Its advanced design comprises 13 devices, including a heavy-duty drum, high-powered motor, and precise coupling, to deliver a powerful centrifugal force that separates particles with ease. The resulting clear liquid displays superior quality, making it ideal for use in the chemical industry.
3. Application Examples
(I) Application in Polyethylene Processing
In the production of polyethylene, centrifuges play a crucial role in separating related materials. However, due to the potential risk of burning or even exploding during the separation process, it is important to use explosion-proof centrifuges. By adding the polyethylene suspension to the centrifuge and subjecting it to high-speed rotation, a significant centrifugal force is generated to separate the powder from the diluent. This separated powder is then further processed through steam distillation. In order to ensure safety, inert gases like nitrogen can be used during the separation process to prevent any chemical reactions. Experience safe and efficient production with the use of explosion-proof centrifuges. By utilizing high-speed rotation and inert gases like nitrogen, these centrifuges effectively separate materials without risk of explosions. This ensures a smooth and successful separation process for the production of quality polyethylene.
(II) Application in coal mining
The extraction process for non-renewable energy sources, like coal, often leads to large amounts of waste and impurities. Traditional manual separation methods only contribute to this issue by producing a small amount of usable materials, resulting in significant waste. This leads to increased capital investment and the consumption of manpower and material resources, making it difficult for enterprises to efficiently use non-renewable energy sources.
To address these practical challenges, most companies have turned to centrifuges for separation. By taking advantage of the different densities and masses of harmful gases and impurities from related raw materials, centrifuges can effectively separate these components. The resulting recovery liquid usually contains three distinct fluids, which can then be separated based on their various properties. With the use of centrifuges, companies are able to efficiently and effectively separate harmful gases and impurities from non-renewable energy sources. This process results in a higher percentage of usable materials, reducing waste and the need for manual separation methods. As a result, enterprises are able to make better use of their non-renewable energy resources, leading to increased efficiency and reduced capital investment and consumption of resources.
(III) Application in the processing of petroleum raw materials
During the production and processing of petroleum, a significant amount of waste is generated. This waste contains a small amount of petroleum, which can cause waste of raw materials and increase production costs if it is not filtered. Traditional filtering methods, such as using filter cloth or tools, can lead to blockages and costly equipment repairs, with low efficiency and failure to completely filter out crude oil. Using large and advanced imported instruments for filtration can also significantly increase costs, potentially leading to a scenario where the expenses outweigh the benefits. To combat these challenges, many companies have turned to centrifuges as their primary solution.
These powerful machines use high-speed rotation to separate petroleum from waste, based on their varying densities. Not only are centrifuges easy to operate and utilize, but they also provide a faster and more convenient working condition for staff members. It’s an expert solution for managing waste and cost-effectively obtaining high-quality petroleum. The advanced centrifuges employ high-speed rotation for quick, efficient, and thorough separation of petroleum from waste without the risk of equipment damage.
(IV) Application in industrial wastewater treatment
In the chemical industry, a significant amount of wastewater is created, which, if released directly, would cause harm to the environment. Thus, it is crucial to treat this wastewater. Generally, industrial wastewater has high levels of acidic or alkaline materials. To neutralize it, substances with the opposite properties are used. However, this process often results in the formation of large amounts of solid substances, which can impede the effectiveness of neutralization. To address this issue, a centrifuge is commonly employed, with the addition of specific chemicals to aid in the separation process. Overall, treating wastewater in the chemical industry is essential to prevent environmental harm. This is achieved through a neutralization process using substances with opposite properties, which can result in the formation of solids. Luckily, a centrifuge and specific chemicals can be used to effectively remove these substances and ensure the success of the treatment process.
