Technical Field
The invention relates to the technical field of sludge dehumidification, in particular to a solar sludge heat pump dehumidification system.
Background
Sludge dehumidification, also known as sludge dewatering, refers to a process of removing most of the water content from sludge by the action of percolation or evaporation, and generally refers to the use of self-evaporation facilities such as sludge drying beds (beds). After the sludge is concentrated, the water content of the sludge is further reduced by a physical method, so that the sludge is convenient to transport, accumulate, utilize or further treat. Dehydration (anhydration) includes two methods, natural evaporation and mechanical dehydration. The mechanical dehydration method is traditionally called sludge dehydration, and the natural evaporation method is called sludge drying. Although the methods are different, the method is a measure for further reducing the water content of the sludge. The existing sludge dehumidifying equipment is unreasonable in structural design, needs to dry sludge by utilizing hot gas generated by combustion of a furnace or hot gas heated by other heating equipment, consumes a large amount of resources, is extremely high in cost, and is extremely not suitable for the development direction of mass production of energy.
