Disc stack separator supplier 2024: The use of three-phase separation technologies is rising in the separation industry. When it came to separating oils and water, the industry particularly needed high-efficiency three-phase decanter centrifuges. Shenzhou Machinery Company has over 50 years of experience in the separation field, which they used to develop the 3 Phase decanter centrifuge. Its primary use is in solving the problem of simultaneous immiscible liquid and solid phase separation using the specific gravity difference. The need for stable, continuous operation around the clock can be met by the 3 Phase decanter centrifuge thanks to its mature design and high-quality raw material selection.

The advantages of centrifugal casting – Using centrifugal casting, parts have greater strength because grain structures are denser. Its mechanical properties are almost equal in all directions, as the process allows for more control over directional solidification. As a result of this increased structural density, the component has a longer life span and is more stress tolerant. The improved structural uniformity and reduced internal porosity of the components also contribute to enhanced part strength.
The activated sludge flocs are slightly refined, with abnormal color, poor settling performance, turbid supernatant, and many small feathery sludge fragments; 2. Microscopic examination can reveal protozoa, but their numbers have sharply decreased. During the microscopic examination process, protozoa were found, but most of them have died or lost their activity; Under the microscope, the volume of sludge flocs is smaller and scattered than usual; 3. The sludge in the sedimentation tank floats in a cloud like manner, resulting in severe mud leakage from the effluent; 4. The final effluent quality is turbid, and the COD detection index is far higher than the normal fluctuation range; First, let’s understand the process of sewage treatment. Kitchen and restaurant sewage first enters the oil separator to remove large particles and floating oil before entering the regulating tank. Automatic grid: Set up a grid to remove large particulate matter and impurities in sewage, ensuring the continuous operation of subsequent treatment devices. The grid residue is regularly manually treated. After removing the floating debris, the sewage enters the regulating tank. A submersible sewage pump is installed in the regulating tank to lift the sewage, and a mixing system is set up in the regulating tank for stirring to prevent sediment.
The materials then flow into the inner cavity of the bowl, which rotates in synchronization with the bowl. Because of their different specific gravities, the three types of centrifugal forces are as follows: the strongest for solids, the second strongest for heavy-phase liquids (like water), and the weakest for light-phase liquids (like oil). This allows the centrifugal force to work magic, forming an outer solid layer and two inner liquid layers. The solid material that has been deposited on the inside wall of the bowl is moved to the machine’s solid outlet using the screw, where it is dried further using extrusion and subsequently released. Meanwhile, the liquid material flows to the machine’s liquid phase outlet and overflows at various points, separating the solid, heavy, and light liquid phases. The Shenzhou Machinery 3-phase decanter centrifuge uses centripetal pump technology to determine the optimal placement of the liquid discharge layer based on the relative proportions of the heavy and light liquid phases and to adjust the position of the neutral layer of these phases. Additionally, the centripetal pump serves as the heavy liquid phase flow outlet, making it an ideal choice for pipeline layout.
Deciding on a decanter centrifuge for laboratory use, particularly among 2-phase and 3-phase centrifuges, calls for a deep understanding of the lab’s desires. This relies on the knowledge to be processed, desired efficiency, area constraints, and budget. 2-phase decanter centrifuges are versatile because they separate solids from liquids without problems. But, 3-phase models, which separate immiscible beverages and solids, are exceptional for complex separations. This guide provided the necessary information regarding decanter centrifuges and their basic features, workings, and evidence comparison. Two immiscible liquids or a liquid and solid can be separated using the two-phase centrifuge. The separation happens automatically and in real-time, without human intervention. Environmental protection, sewage treatment, the chemical industry, food processing, fermentation, medicine, and mining metal and non-metal minerals are just a few of the many applications for two-phase centrifuges.

The structure and working principle of a Decanter centrifuge – The Decanter centrifuge relies on the density difference between solid and liquid phases, and under the action of centrifugal force, accelerates the settling speed of solid particles to achieve solid-liquid separation. There is a conical section designed in front of the drum, which rotates at a set speed according to the different properties of the material. The material rotates at the design speed on the inner wall of the drum, forming a concentric liquid layer along the drum shell, called the liquid ring layer. The solids contained in the material are deposited onto the wall of the drum under the action of centrifugal force, and then the dry material is pushed out of the drum through spiral operation. The operating speed of the drum directly determines the separation factor, while the speed difference of the screw directly affects the solid moisture content transported outside the drum. It has a direct impact on processing capacity, residence time, and solid discharge.
