Problems solved by technology

But at present, the drying and upgrading of lignite is still limited to the application of rotary drum drying and dehydration technology, which not only consumes a lot of energy, but also has high carbon emissions, and the phenomenon of over-grinding during the drying process is serious. The subsequent wet dust removal consumes a lot of water and causes serious air pollution. The key is Lignite has a low ignition point and can easily cause coal dust explosions. Corresponding safety precautions must be taken in the production process

Embodiment 1

[0053] Such as Figure 1~Figure 10 As shown, the high water content viscous or non-viscous wet material hot-press drying dehydration equipment provided by the present invention includes a wet material introduction bin 1, a hot-press drying bin 2, a dry material flash bin 3, a filter belt moving system 4, Fluid heat medium system 5, air intake system 6 and air outlet system 7.

[0054] The air intake system 6 includes pipes through which steam or compressed air can be introduced.

[0055] The gas outlet system 7 includes the gas outlet pipeline of the dry material flash bin 3 and the gas outlet pipeline of the hot-press drying bin 2 . The air outlet pipe of the dry material flash chamber 3 is connected with the induced draft fan 7a.

[0056] Valves F1, F2 and F3 are respectively provided on the pipes leading into the steam and compressed air of the air intake system 6 and the gas outlet pipes of the hot-pressed drying chamber 2.

[0057] The wet material introduction bin 1 i...

Embodiment 2

[0064] Such as Figure 11 As shown, only saturated steam or no heat medium is fed into the upper channel 10a of the thermal pressure head 10, the valve F2 is opened periodically, compressed air is introduced into the lower channel 10b, and the moisture of the wet material is blown out. The wet material to be processed is hot or preheated, and the temperature of the material can be 30°C to 99°C.

[0065] The working procedure of the wet material introduction bin 1, the hot-press drying bin 2 and the dry material flash bin 3 is the same as that of the embodiment 1, except that the pre-compression step is cancelled, and the hot material is directly applied in the hot-press drying bin 2 with 1MPa~ The mechanical compression pressure of 10MPa strengthens the mechanical extrusion to remove the moisture of the wet material, and other working procedures are the same as in Example 1.

[0066] The hot press drying and dehydration equipment for highly water-containing viscous or non-vis...

Description

technical field [0001] The invention relates to a device for dehydrating wet materials, in particular to a device for hot-pressing, drying and dehydrating wet materials with high water content and viscosity or non-viscosity. Background technique [0002] Materials such as municipal sludge, papermaking sludge, printing and dyeing sludge, or mineral processing tailings are inevitable products of their production processes, some of which contain certain organic components, and some contain certain inorganic mineral components, that is, they still contain certain biomass Energy, heat or mineral resources. This kind of material is obtained by mechanical filtration or centrifugal dehydration. It has the typical characteristics of fine particle size, high viscosity and high moisture content. It cannot form its own shape, and its storage and transportation characteristics are extremely poor. The by-products not only seriously waste energy resources, but also form secondary pollutio...
