Key innovations
The innovation of the technology lies in that the solvent is used for efficient dehydration at room temperature and proper pressure, so that the moisture content of sludge is obviously reduced and high calorific value is maintained, and the sludge can be directly used as fuel to replace coal, thereby realizing resource utilization, energy conservation and environmental protection.
Potential economic benefits
Substituting coal saves fuel costs; the technology is cheap and easy to industrialize. Sales revenue can be obtained through complete production of equipment, and the market prospect is broad.
Potential climate benefits
This technology turns sludge into a fuel alternative to coal, directly reducing carbon dioxide emissions from the combustion of fossil coal. At the same time, the energy consumption and carbon footprint of sludge transportation and subsequent treatment are reduced.

Solution details

Introduction to the results:

Municipal sludge solvent deep dehydration technology is a new technology that uses liquid solvent extraction to remove water from sludge. At room temperature and moderate pressure, liquid solvent can be effectively used for deep dehydration of sludge. At present, a pilot experimental device has been designed and manufactured by ourselves. It can process up to 1Kg of sludge each time and a maximum of 50kg of sludge per day. It can achieve a moisture content of 40% after sludge dehydration, and a minimum of 17.3%. The calorific value of the sludge is reduced by 10%, and the sludge is directly used as fuel after dehydration to replace coal.


Outcome advantages:

This technology has the advantages of low price, wide application, environmental protection, cleanliness, and easy industrial production, so this technology has excellent industrialization prospects. The technology has applied for a national invention patent, and it is intended to combine related machinery manufacturing companies and environmental protection equipment companies to carry out complete production of sludge solvent deep dehydration equipment.
