Improvement of dewatering efficiency of decanter centrifuge and its wide adaptability

 

In the process of using the decanter centrifuge, we encountered the problem of slow dewatering efficiency of the decanter centrifuge. The specific manifestation is that as the fixed image material in the drum increases, the dewatering time of the decanter centrifuge is prolonged, and the decanter is not dried. appear. This phenomenon is common.

  In response to this problem, first of all, the rotating speed of the decanter centrifuge drum should be increased, of course, within the safe allowable range, and the material is non-corrosive or less corrosive. Secondly, increase the filtration area in the centrifuge drum. The method is to increase the lining net to keep a tiny gap between the filter bag and the centrifuge drum to increase the water permeability; increase the cross-sectional area, such as adding a V-shaped filter baffle.

   It can be dehydrated in a small amount for multiple times, reducing the amount of dewatering and filtering material in each centrifuge, and the method of discharging more and less. If the material is sticky, wash it within the allowable range of the process. Increase the particle size of the solid phase material. If the process is unchanged, if you want to increase the worry rate, you can consider adding, such as a flocculant.

   Decanter centrifuge is one of the widely adaptable solid-liquid separation equipment on the market, which is mainly used for solid-liquid separation. When selecting the equipment, it depends on the specific conditions of the materials. The separation and separation effect of the decanter centrifuge is determined by the dryness of the solid particles in the suspension, such as salt sugar and other water-soluble items, which need to be used. The flocculant is then separated.

   Although the applicability of the decanter centrifuge is wide, when we choose the centrifuge equipment, we must first according to our own needs, and then choose the one that suits us.

Soy protein extraction centrifuge

on . Posted in News

Soy protein extraction centrifuge

Soybeans have complete protein properties and contain all the amino acids we need in our diet, and our body simply cannot synthesize them.

This means that soy protein products are an excellent substitute for animal products and animal food. They are also a good source of whole protein, but their disadvantage is that they are more fat, especially saturated fat.

Soy protein is now one of the main protein sources consumed by livestock and humans. Soy Protein Isolate (SPI) contains 90% protein (based on dry weight) and is the most concentrated form of soy protein currently available.

Therefore, the separation and extraction of soy protein is becoming an important production line in the food processing industry and decanter centrifuge is an important equipment for this field.

Vegetable protein is extracted from soybeans, peas, etc. by the usual acid extraction method. In addition to nutritional value, plant protein also has many important functional properties. In the process of producing protein powder, in order to maximize the yield and extraction rate, more and more decaner centrifuges are used in the entire production line.

Separation technology High-speed soybean protein centrifuge (separation coefficient ≥3500G) plays an irreplaceable important role in the production process. The most hygienic and effective way to deal with SPI is to use a can analyzer centrifuge for centrifugation.

Soy protein isolate (SPI) is currently the most concentrated low-fat and high-protein nutritional food, and its market demand is very large. In the soybean product industry, high-efficiency, fully enclosed high-speed centrifuges are gradually bringing technological innovation to the soybean production line and replacing traditional filter equipment. Ordinary centrifuges are difficult to remove soybean hulls (similar to medium density).

For this reason, Separation Technology has designed and developed a float trap to solve this problem and make the separated soybean milk meet the processing and production requirements.

 

Technology extraction process

The principle of producing soy protein isolate is simple.

First, defatted soybean meal or flakes are used as a raw material to dissolve protein in water.

The resulting solution is then separated from the solid residue.

Finally, the protein precipitates out of the solution, then separates and dried.

For these companies in the soy protein industry, the main goal is to improve product purity and yield. These depend on many different parameters, including alkalinity, extraction time, temperature, water to soybean meal ratio, heat treatment and stirring.

Soy protein centrifuge is specially designed to solve this problem, helping customers achieve high purity and high efficiency economically.

Protein extraction

Mix soy flour with water and perform isoelectric adjustment to dissolve most of the protein. Then the protein-rich solution must be separated from the solid phase called okara.

The traditional configuration includes a vibrating screen and a rotating screen, followed by selected purification and concentration.

Waste oil recycling decanter centrifuge

on . Posted in News

Waste oil recycling decanter centrifuge

Waste oil is produced from oil in oil production, pipeline transportation, oil and gas joint stations, oil refineries and oily wastewater.

Waste oil treatment is a complete production process, using the principles of centrifugal separation and demulsification oxidation. The main equipment is composed of batching system, feeding system, separation system, conveying system and control system.

After collecting waste oil and heating it with steam, add appropriate amount of additives, such as demulsifier and active agent, to make the emulsified oily water into liquid.

The high-efficiency three-phase waste oil decanter centrifuge is used to realize the continuous separation of oil, water and slag in the sludge.

The separated undemulsified water and oil-water mixture are directly sent to the sewage treatment system, and are dehydrated by an efficient two-phase waste oil centrifuge.

The crude oil residue in the dehydrated slag phase can be recovered through combustion or thermal desorption process. The separated crude oil is collected and then purified by a three-phase disc separator. The purified oil can be reused.

The waste oil decanter centrifuge can also treat the oily (wastewater) produced during the processing of crude oil. Used for coarse flocculation + dehydration treatment. After dehydration, the slag phase is directly incinerated.

This treatment method causes a lot of waste of crude oil resources. Now, we can apply a series of pretreatment processes (adding demulsifiers, surfactants, etc.), and use efficient three-phase waste oil centrifuges to realize the reuse of crude oil resources.

After collecting the oily (waste water), add an appropriate amount of demulsifier and active agent, the oily water in the emulsified state becomes liquid, and the demulsified oily (wastewater) naturally settles and separates in the oil. trap.

The undemulsified water and oil-water mixture in the middle layer of the oil collector are directly sent to the sewage treatment system for treatment.

An efficient two-phase waste oil centrifuge is used for dehydration. The oil floating in the upper layer of the oil collector and the sludge deposited in the lower layer are collected, and then sent to a stirred tank for further processing.

Through the high-efficiency three-phase waste oil centrifuge, the oil, water and slag in the treated sludge can be separated continuously.

Waste oil centrifuges can also be used to drill oil-based muds. Its basic ingredients are oil, water, organoclay and oil-soluble chemical treatment agent. OBM resists high temperature and calcium salt erosion, which is conducive to the stability and lubrication of the well wall.

The mud has good lubricity and little damage to oil and gas layers, so it is widely used in drilling platforms. However, the slag produced in the equipment (vibrating screen, centrifuge and dryer) of the drilling solids control system seriously affects the environmental safety and must be treated in a harmless manner. After treatment, the oil content in the slag is less than 1%, and the oil is further purified and reused.

The collected drilling OBM wastewater is agitated at a high speed in proportion, and an appropriate amount of demulsifier, active agent and other additives are added to make the oily water in the emulsified state into a liquid state.

Before separation, use a vibrating screen to remove large particles of soil, sand, glass bottles, mineral water bottles, convenient bags, gauze and other solid waste, and then use an efficient two-phase waste oil centrifuge to separate oil, water and slag continuously.

After being heated by steam, the separated liquid phase enters the sedimentation tank, where the supernatant liquid is removed, and the liquid phase settles at the bottom and is mixed with the slag separated by centrifugation. The remaining oil is recovered through a thermal desorption process.
