焚烧底灰湿法分选（或湿法分离）是一种利用水或其他液体介质分离底灰不同成分的技术。与干法分选相比，湿法分选具有一些明显的优势：

1.提高排序准确率

• 细颗粒分离：湿 选能够更有效地分离细颗粒物质，特别是对于粘在一起的颗粒，水分可以帮助松散这些颗粒并提高分选的准确性。
• 减少颗粒之间的摩擦：液体介质可以减少颗粒之间的摩擦，使得分选过程更加顺畅，并减少物质之间的粘附。

2.提高金属回收率​

• 减少金属损失： 湿式分离技术可减少因干燥过程中产生的灰尘和气流造成的金属损失，从而提高金属回收率。

3.Reduce Dust and Noise

• Dust Control: Wet sorting reduces dust generation in the bottom ash through liquid media, reduces dust pollution in the air, and helps to improve the working environment.
• Reduced Noise: Wet sorting equipment typically produces less noise than dry sorting equipment, helping to reduce noise pollution in the plant.

4.Improve The Physical And Chemical Properties Of Treated Bottom Ash

• Wetting Treatment: Wet sorting can provide proper wetting when handling bottom ash, which can help reduce bottom ash build-up issues and improve treatment efficiency.
• Better Handling Of Viscous Materials: Wet sorting technology is particularly effective for handling sticky or caking bottom ash, as water can help reduce the stickiness of the bottom ash and improve the treatment results.

 5.Reduce Environmental Impact

• Wastewater Treatment: While wet sorting produces wastewater, it can be treated for reuse or properly disposed of, reducing the negative impact on the environment.
• Reduce Secondary Pollution: Wet separation reduces the release of fugitive dust and pollutants in the air, reducing the pollution to the surrounding environment.

6.Improve The Durability Of The Equipment

• Equipment Protection: Wet sorting can reduce the wear and tear on equipment caused by dust and friction in dry separation, thereby extending the life of the equipment.

Practical Application Examples

Example 1: The Jingdezhen incineration bottom ash separation plant in Jiangxi Province uses wet sorting technology, which is able to handle viscous bottom ash, and after a period of operation, the metal recovery rate has increased by 8% and the dust emission has been reduced by 40%.

Example 2: Another plant uses wet sorting to process bottom ash with a large number of fine particles, achieving higher sorting accuracy and a stable operating environment by optimizing water flow and sorting processes.

In general, wet separation has obvious advantages in terms of improving sorting accuracy, metal recovery, reducing dust and noise, etc., and is suitable for handling complex and cohesive incineration bottom ash. However, it is important to note that wet sorting also generates wastewater and needs to be properly treated to comply with environmental requirements.

When deciding whether to use wet or dry separation to treat incineration bottom ash, RUIJIE Incineration Bottom Ash Equipment Manufacturer recommends that you consider the following key factors:

1.Characteristics Of Incineration Bottom Ash

• Wet Sorting: suitable for handling viscous bottom ash with fine particles. Wet sorting can effectively reduce the adhesion of the bottom ash and the treatment efficiency is higher, especially when there are a large number of fine particles or adherent substances in the bottom ash.
• Dry Sorting: suitable for handling large particle size bottom ash or non-adhesive bottom ash. If the bottom ash is dry and does not clump easily, dry sorting can provide good treatment.

2.Environmental Protection Requirements

• Wet Sorting: with low dust emission, environmentally friendly, in line with strict environmental regulations. It is suitable for areas or factories with high environmental protection requirements
• Dry Sorting: More dust may be generated, and an effective dust collection system is required to control dust emissions. If environmental regulations are more relaxed, dry sorting may be a cost-effective option.

3.Equipment and Maintenance Costs

• Wet Sorting: Usually requires more equipment and maintenance, such as water treatment systems, wastewater treatment facilities, etc. The initial investment is higher, but it can provide higher recovery efficiency and better sorting accuracy.
• Dry Sorting: The equipment and maintenance costs are relatively low, the technology is mature, and the operation is relatively simple. Ideal for those with limited budgets or large throughput.

4.Recovery Rate And Sorting Accuracy

• Wet Separation: can improve recovery, especially when working with fine particles and metals. Wet sorting typically provides higher sorting accuracy and metal recovery.
• Dry Sorting: While dry sorting technology also provides good recovery, it may not be as effective as wet sorting when dealing with fine particles or adherent substances.

5.Processing Capacity

• Wet Sorting: Suitable for treating large quantities of bottom ash, but it is necessary to ensure the stable operation of water sources and wastewater treatment systems.
• Dry Sorting: large treatment capacity and independent of water source, suitable for high treatment capacity.

RUIJIE Recommends The Plan

If the environmental requirements are high, and the bottom ash has strong adhesion or contains a large number of fine particles, wet sorting is recommended.

Wet sorting can effectively reduce dust and improve sorting accuracy, and is suitable for handling complex bottom ashes.

If you have a limited budget and the bottom ash is dry or does not have strong adhesion, dry sorting may be a more economical option.The investment in dry sorting is not as large as that in wet sorting plants, and the operation is simple.

Mixed Use: In some cases, wet and dry sorting technologies can be combined to take advantage of the best of both. For example, dry sorting is used for initial processing, followed by wet sorting to improve sorting accuracy and recovery.

Practical Examples

1.Wet Sorting Case: An incineration bottom ash treatment plant in Germany uses wet sorting technology to meet strict environmental standards and improve metal recovery.

2.Dry Sorting Case: A large incineration bottom ash separation plant in the United States uses dry sorting technology, mainly considering cost-effectiveness and processing capacity.

When choosing the right sorting technology, RUIJIE Supplier suggest that you should comprehensively consider the characteristics of the bottom ash, environmental protection requirements, economic budget and technical conditions.

Incineration bottom ash is mainly composed of unburned substances, fly ash, slag, metal residues, and other substances produced during incineration. Its composition varies depending on the type of waste incinerated and the treatment process.

Incineration bottom ash can be treated by physical, chemical, and biological treatment methods. For example, by curing/stabilizing the treatment to reduce their hazards, or by recycling metals and other useful ingredients.

Incineration bottom ash can contain heavy metals and toxic substances, which can contaminate soil and water sources if not handled properly. Therefore, proper handling and disposal measures are necessary to reduce the impact on the environment.

The metals and minerals in the incineration bottom ash can be recovered and reused. For example, the metal in the bottom ash can be recovered through physical separation and metallurgical treatment and reused in industrial production.
