Negative pressure thermal evaporation equipment and technology of interventional activated carbon fiber boards

Abstract

The invention relates to negative pressure thermal evaporation equipment and technology of interventional activated carbon fiber boards. The negative pressure thermal evaporation equipment is formed by an evaporation assembly, a centrifugal cyclone gas-liquid separation assembly and a negative pressure gas exhaust assembly. The technology is characterized by immersing activated carbon fiber boardsin a raw material in need of heat evaporation and solid-liquid separation, adsorbing the heated raw material, exposing the raw material in negative-pressure space, evaporating the liquid raw material, and collecting the evaporated liquid in the centrifugal cyclone gas-liquid separation assembly. By adopting the activated carbon fiber boards as an evaporation surface basic material, the negative pressure thermal evaporation equipment provided by the invention has the advantage of large specific surface area, i.e., large evaporation surface area; the activated carbon fiber board is acid-resistant and alkali-resistant and can absorb water; the evaporation temperature of liquid can be reduced by adding negative pressure.
