Coal gasification fine slag dewatering and resource utilization project

I. Project background:
A modern coal chemical enterprise (coal to olefin, coal to ethylene glycol, etc.) produces a large amount of coal gasification fine slag rich in carbon and ash in its coal gasification unit.. These fine slag have a high moisture content, occupy a large area for stacking, and the residual carbon in them has recycling value.

II. Challenges and Needs:

The material particles are extremely fine (-200 mesh accounts for over 90%), and traditional dehydration equipment has low efficiency. The moisture content of the filter cake is often higher than 40%.

I hope to reduce the moisture content of the filter cake for transportation and subsequent disposal or resource utilization (such as co firing for power generation and brick making).

Efficient, continuous, and large-scale dehydration equipment is needed to adapt to the scale effect of coal chemical industry.

III. Nuclear Xu Solution:
We provide large-scale  DURubber Belt Vacuum Filter  Enhanced solution:

1.Ultra long filtration zone: The filtration length is extended, providing sufficient dehydration time for extremely fine materials..

2.Polyelectrolyte dosing system: Integrated intelligent flocculation system, by adding specialized flocculants, enables fine particles to agglomerate into larger flocs, greatly improving dehydration speed and efficiency..

3.Nuclear Xu filter cloth technology: Select a special filter cloth with a smooth surface that is not easy to adhere, and combine it with a strong flushing system to ensure continuous and efficient filtration capacity..

4.Data Collection and Remote Operations: Equipped with cloud platform interfaces, it can monitor operational data in real time, provide early warning and remote technical support..

Fourth, Application Effect and Customer Value:

1.Dehydration breakthrough: The moisture content of the filter cake has decreased from>40% to  25-30%， Implemented“ Using slag to determine water; To“ Using water to determine slag; The transformation has become; Fine slag dry discharge; Provided key technical equipment.

2.Cost savings: The heating value of the filter cake is increased, which can be used as fuel for co firing, creating economic benefits;; Reduce transportation and storage costs by approximately 50%.

3.Technical Benchmark: The success of this project has made Nuclear Xu Machinery a reliable supplier of fine slag dewatering solutions in the coal chemical industry..
