Description

Device for preparing municipal sludge derived solid fuel

Technical Field

The utility model relates to a solid waste energy comprehensive utilization technical field, especially a preparation municipal sludge derived solid fuel's device.

Background

Municipal sludge comprises biological treatment of municipal domestic sewage treatment plants, such as sludge produced by an activated sludge process and a biofilm process, sludge produced by dredging urban sewers and river channels and the like. The municipal sludge has the characteristics of complex components, high yield, high water content, high pollution and the like. In the processes of sludge storage, transportation and treatment, leachate is very easy to generate to pollute the underground water, and harmful gas volatilized at any time can pollute the surrounding atmosphere. The treatment modes of single anaerobic treatment, drying treatment, incineration, landfill, composting and the like are the most adopted treatment modes at present, and the defects of incomplete treatment, secondary pollution transfer, high cost and the like are the concentrated existence of various methods.

Currently, 3 types of sludge resource utilization modes are mainly used for land utilization, building material utilization and biomass fuel preparation, wherein the biomass fuel preparation is a mode of mixing sludge with industrial and agricultural wastes or clean fuel to prepare fuel with higher heat value for boiler combustion, and is a main mode of sludge resource utilization. The sludge prepared molding fuel mainly utilizes the characteristic that the sludge has lower heat value and can not be directly combusted, and the sludge is mixed with combustible to prepare the biomass fuel which is used as energy, so that the heat value of the sludge is fully utilized, the cost of sludge treatment is effectively reduced, and the sludge prepared molding fuel is an effective way for harmlessness and recycling of the sludge.

The waste mushroom sticks are used as substrates for cultivating edible mushrooms, and mainly comprise sawdust, corncobs, cottonseed hulls and the like, and simultaneously contain a large number of pollution factors such as mixed mushrooms, plant diseases and insect pests, insect eggs and the like. In recent years, the fungus industry in China is rapidly developed, a large amount of waste fungus sticks are generated when edible fungi are planted, the traditional treatment method is abandonment or direct incineration, and the pollution and the hazard to the environment are also increased. Researches show that the waste mushroom sticks contain a large amount of structural polysaccharide and lignin and have biomass energy utilization potential. The waste mushroom sticks have rough surfaces, are rich in lignin and cellulose, have cohesiveness and can form stable skeletons, so that the molding fuel is easy to prepare.

The municipal sludge has high organic matter content, high heat value and less harmful toxic substances, is mixed with the waste bacteria stick to prepare the biomass fuel which is used as energy, and is an effective utilization mode for the municipal sludge fuelization. However, no special equipment is currently available for preparing the above-mentioned sludge waste bacteria rod-derived solid fuel.
