Solid-liquid separation of coal slime

I asked further: This circulating water contains a large amount of sludge – does that sludge come from the dust removal process in the flue gas? There are many solutions to this problem. To address it at its source, you need to change the dust removal and recycling methods used; spraying water yields the result mentioned earlier. If cyclone dust removal is employed first, followed by electrostatic dust removal, then the dust will likely be dry, and it can be transported via conveyor belts back to the boiler or sold as slag. If the existing treatment methods are continued, solid-liquid separation can be carried out from the circulating water, using filters such as pressure filters or vacuum filters, as well as horizontal screw dryers. If treatment is to take place in a sedimentation tank, slurry pumps, mortar pumps, or coal slurry pumps can be used to transfer the material to a horizontal screw dryer or to a filter for solid-liquid separation; this process helps to remove moisture, reducing it to around 15%. You may want to consult relevant manufacturers or visit companies that use similar processes to learn more.

The flue gas is a flammable and explosive gas; some of the dry ash has been removed from the cyclone dust collector, but some ash remains and is carried away by the circulating water. We also considered using filter presses for liquid removal, but the filter presses we have encountered generally have a small processing capacity. Does the selected compressor take up a lot of space? Are there any units or manufacturers that use 50T/h equipment to process slurry coal?

Are there any analyses on the particle size and density of coal slime? How much is it? Where does coal slime come from? Is there any residual heat? Could you tell me?

The gas generation furnace we use produces water gas from lump coal as raw material. The water gas generated in the furnace carries coal ash with it; part of the coal is discharged in the form of dry ash, while another part is introduced into the circulating water as wet ash via a water washing tower. The temperature of the circulating water is around 50 degrees, and after sedimentation through micro-vortices, the clear water is sent to a cooling tower for temperature reduction, while the coal ash is discharged from the micro-vortices. Due to the high moisture content of wet coal ash, a large area is required for drying. If there is appropriate dehydration equipment, the problem can be solved. So, does anyone know if there are any devices available for handling 50 tons of wet coal ash, and what space such devices require?

It turns out to be a water-gas furnace – a very familiar type of equipment. I worked with it alone for a few months; the amount of ash produced was 50 tons per hour. How much coal must that require? Since it’s a closed-loop water system, it would be best to use a filter press, either a belt filter press or a plate filter press. But 50 tons of ash per hour is indeed an enormous amount. The furnaces I operated produced less than 1 ton of coal per hour
