The use and value of manure processed by decanter centrifuge

The first use of manure for electricity generation is relatively mature technology. Use cow dung to generate electricity and make substitutes for biogas and coal. For example, in dairy farms, the annual electricity generated by the fermentation of dried cow manure processed by a cow manure Decanter centrifuge can save 1.2 million yuan in electricity costs. In addition, cow dung sticks and cow dung honeycomb coal can also be developed in a certain place. Cow dung sticks made of cow dung are used as fuel, and the combustion value is high. Cow dung honeycomb coal is compressed with cow dung and coal at a ratio of 4:6, which solves the problem of honeycomb coal.

The second use of feces

Feces can also grow Agaricus bisporus and straw mushrooms. The cow dung produced by the milk buffalo is used for biogas power generation. The produced biogas slurry can be made into liquid fertilizer, and the fertilizer is sold for more than 3,000 yuan a ton. The milk produced by milk buffalo is about 4 yuan, but the fertilizer can sell for 100 yuan. This shows that the use of cow dung can not only increase the economic income of cattle farmers, but also bring many economic and social benefits. In order to solve the problem of farming wastewater pollution and build an environment-friendly farming base, the company’s leaders attach great importance to pollution control work, and entrusted our unit to design a plan for the fecal sewage solid-liquid separation treatment project. In order to complete this work with high quality, the Decanter centrifuge is recommended to be used.

The dried cow dung dehydrated by the cow manure Decanter centrifuge can also be used as feed for many animals. The cow manure contains minerals and various nutrients, including organic matter, total nitrogen, crude protein and other nutrients.

After the manure is processed by the decanter centrifuge, according to the similar project investigation and the information provided by the owner, the sewage mainly comes from cow urine and ground washing wastewater, and contains manure and urine.

According to the requirements of the owner, it is necessary to treat about 300 tons of manure sewage produced by 4000 cows every day, and the moisture content of the dried cow manure after treatment is about 60%-70%. The excrement processed by the decanter centrifuge can greatly increase the income of the enterprise, and truly turn waste into treasure.

Common causes and solutions of decanter centrifuge vibration

If the vibration is too large during the use of the Decanter centrifuge, it will cause the fatigue damage of the drum in advance, the connection bolts will be loose and broken, and even the differential will separate from the drum, causing an accident and affecting the service life. This passage will share some key information about the common causes and solutions of decanter centrifuge vibration

2022.10.28 mining tailing decanter centrifuge

1. During the maintenance and assembly, the score lines of the drum are not aligned; the accuracy of the dynamic balance is destroyed. Solution: Realign the reticle.

2. The lubricating oil deteriorates. Solution: Replace as described in the instruction manual.

3. The main bearing of Decanter centrifuge fails. Solution: replace the bearing.

4. The inner ring of the main bearing loosely cooperates with the shaft. Solution: Repair or replace the end cap.

5. The screw conveyor bearing fails. Solution: replace the bearing.

6. The bolts of the liquid outlet and the slag outlet are not tightened or the pipes are rigidly connected. Solution: Tighten the bolts, and change the elastic flexible connection of the pipeline.

7. Loose flange of the machine head causes vibration of the differential. Solution: replace the head flange or small end cover.

8. The differential is damaged (generally caused by lack of oil). Solution: replace the differential parts.

9. After the stop, the valve is not tightly closed and the material is fed, which causes the accumulation of material in the drum and the partial weight. Solution: wash in water, when the accumulation of material is serious, use the counter-clockwise steering wheel to drive the auxiliary pulley of the differential after stopping to discharge the material. After the accumulation of material is discharged, it can be put into use again.

10. The joints of rotating parts are loosely deformed. Solution: Check and repair.

11. The replacement of the new parts has a poor dynamic balance. Solution: adjust or replace.

12. The related parts are worn seriously. Solution: Replace and repair.

13. The material accumulated in the casing rubs against the outer drum. Solution: clean up or flush regularly.

Difference of Rotating Speed of Decanter Centrifuge

The bowl‘s rotating speed in a Decanter centrifuge can be continuously adjusted across a wide range. This rotational speed manipulation allows control over the separation factor of the decanter centrifuge, catering to diverse mud specifications. Generally, for sludge with larger particles and higher density, a lower separation factor is ideal, while a higher separation factor suits sludge with smaller particles and lower density.

2022.10.28 mining tailing decanter centrifuge

For initial settling sludge, a modest αvalue is sufficient to achieve optimal dewatering by Decanter centrifuge. Despite the reduction in particle size for digested sludge, the increased density maintains the need for an αvalue comparable to primary sludge. The activated sludge, characterized by its low density and small particle size, necessitates a larger αvalue to achieve enhanced dewatering, with the required αvalue increasing with higher Specific Volumetric Index (SVI) values and longer sludge age. When activated sludge is in an expanded state, efficient dewatering is achieved through a high-speed decanter centrifuge. The αvalue for mixed sludge depends on the proportion of activated sludge a higher ratio demanding a greater αvalue.

Solids Control Centrifuge

Modifying αvalue, while maintaining consistent mud quality, enhances the solid recovery rate and separation liquid clarity. However, elevating αvalue also increases energy consumption. Hence, unless a high solids recovery rate is imperative, an excessively high αvalue is unnecessary.

GN’s dewatering Decanter centrifuge model is the T series decanter with an 8.5 degree beach angle. Designed primarily for dewatering and thickening, GN’s T series decanter centrifuge is widely used in municipal and industrial wastewater sludge treatment. This centrifuge is engineered to handle materials with significant differences in solid and liquid density, low viscosity, high concentration, substantial treatment capacity, and superior dryness. When dealing with materials like sludge or wastewater containing fine particles, the addition of flocculants aids in aggregating the particles before dewatering with the T series decanter centrifuge.
