Abstract

The invention discloses a paper sludge biomass environmental-protection renewable energy drying system, which has high drying efficiency, good dehydration effect, good environmental benefits, and capability of collecting and treating waste liquor and stinks. The paper sludge biomass environmental-protection renewable energy drying system comprises a screw press primary dehydration device, a biological reaction secondary drying device, a conveying device for conveying paper sludge discharged from the screw press primary dehydration device to the biological reaction secondary drying device, and an electrical-controlled device for automatically controlling the screw press primary dehydration device, the biological reaction secondary drying device and the conveying device. The paper sludge biomass environmental-protection renewable energy drying system can be widely applied to the fields of paper sludge dehydration and drying.

Description

technical field [0001] The invention relates to a paper mud biomass environmental protection renewable energy drying system. Background technique [0002] Currently, the global financial crisis has triggered an energy crisis. Under the situation of decreasing fossil fuels (oil, coal and natural gas), the international and domestic energy sources are tense, the price of coal and other fuels has risen significantly, and the cost of fuel has risen rapidly. Under the influence of many factors, the government has vigorously promoted the transformation of the entire national industrial structure to an intensive economy, and biomass as a renewable energy has become a hot spot in the research of new energy in the 21st century. Biomass fuel has the advantages of low cost, simple operation, easy industrialization and application, etc., and has great development prospects. [0003] Paper sludge is papermaking sludge, which is the terminal product discharged after wastewater treatment...
