Abstract

The invention provides excrement negative pressure evaporation drying equipment. The equipment comprises a power supply system, an excrement drying system, a vacuum negative pressure system and a condensate water recovery system; the excrement drying system is used for receiving excrement materials and heating the excrement materials, and the vacuum negative pressure system is used for forming a negative pressure environment in the excrement drying system and reducing the boiling point of water in the excrement materials. Water vapor generated during excrement evaporation flows into the condensate water recovery system to be cooled and condensed into liquid water, and finally the liquid water is discharged. The power supply system is used for supplying electric energy to the excrement drying system, the vacuum negative pressure system and the condensate water recovery system. The equipment provided by the invention can be arranged in a public toilet, excrement can be directly treated,manual treatment links are reduced, reduction treatment of domestic sewage can be achieved for the excrement, water resources can be saved, valuable resources such as nitrogen and phosphorus can be recycled, cyclic utilization of energy is achieved, and excrement treatment in relatively concentrated areas of families, hospitals, high-speed rails and the like can be rapidly achieved.

Description

technical field [0001] The invention relates to the technical field of domestic sewage treatment, in particular to a device for evaporating and drying feces under negative pressure. Background technique [0002] With the improvement of people's living standards, people's requirements for quality of life are getting higher and higher, and their awareness of environmental safety is getting stronger and stronger. Therefore, it is urgent to improve people's living and working environment. At present, the feces in public toilets are mostly collected manually at regular intervals, which is time-consuming and laborious, and requires a dedicated place for centralized processing, consuming a lot of energy. Contents of the invention [0003] An embodiment of the present invention provides a negative-pressure evaporation-drying device for feces, which is used to provide a device for treating toilet feces in situ. [0004] In order to achieve the above object, the present invention a...
