A large amount of biomass raw materials are abandoned or directly burned in the open air, the abandoned biomass raw materials are naturally decomposed into gases such as methane, and the open air burning without any treatment generates a large amount of dust to cause environmental pollution such as haze. Biomass combustion is zero carbon emissions, considering photosynthesis during plant growth. Therefore, the biomass energy has a wide prospect of high-efficiency utilization no matter from the aspects of energy structure and energy consumption level in China or from the aspects of primary energy storage, power demand and carbon emission reduction. In 2012, each ministry of China successively issued a series of policies to promote the utilization of biomass.
Most of biomass raw materials are wet materials, the yield of the biomass raw materials is greatly influenced by seasonal changes, and the drying of the biomass raw materials becomes one of the indispensable links for ensuring stable raw material supply, transportation, storage and even utilization.
Similarly, the municipal sludge is one of byproducts of a water treatment process of a municipal sewage treatment plant, namely an activated sludge method, has the water content of 60-80 percent and the pH value of 7-12, and contains faecal coliform groups, fluoride, toluene and heavy metal elements such as zinc, manganese, copper, cadmium, chromium, nickel, mercury, arsenic and the like. The wet sludge is large in volume and poor in transportability, and secondary pollution to atmosphere, underground water and soil is easily caused due to improper disposal. The new municipal sludge drying technology which has the advantages of economy, safety and environmental protection adaptability is urgently needed to be developed so as to relieve the municipal treatment pressure and practically realize harmless, quantitative-reducing and resource sludge utilization.
The existing biomass raw material and sludge drying mode needs to remove water in the material by means of high-temperature steam or smoke heat, and all consume high-grade heat. Meanwhile, combustible waste gas generated by a plurality of oil refineries and petrochemical plants is burnt by a torch, so that the atmospheric environment is polluted, and the heat value in the combustible waste gas is not fully utilized.
