Abstract

The invention belongs to the technical field of fuel preparation, and particularly relates to straw fuel containing biomass sludge and a preparation method of the straw fuel. The straw fuel containing the biomass sludge is prepared from the biomass sludge containing straw, a mixture of membrane treatment supernate and straw, lignin and cellulose mud. According to the straw fuel, organic waste obtained through biomass resource treatment is fully utilized, and great economic benefits and environmental friendliness benefits are achieved. In addition, straw particles and other plant materials are added into sludge which is not dewatered, and the thermal value of the dewatered sludge can be increased; due to the fact that the straw particles and other plant fibers are mixed in the sludge, the friction force of the pre-dewatered sludge in a spiral squeezing dehydrator is increased, then the operation frequency of the spiral squeezing dehydrator can be improved, and the operation efficiency and output sludge dryness of the machine are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of fuel preparation, and in particular relates to straw fuel containing biomass sludge and a preparation method thereof. Background technique [0002] A large amount of sludge is produced in the comprehensive utilization of biomass resources and papermaking industries. The treatment of these sludges usually includes sedimentation, gravity concentration, dehydration, and drying. In addition, the dried sludge can be further processed. One of the treatment methods is to incinerate the sludge. However, incineration will further cause environmental pollution, especially air pollution. [0003] Although biomass sludge contains a large amount of organic matter and can generate a certain amount of heat when burned, the calorific value of these sludges is low, usually between 500 kcal and 1000 kcal, and cannot be used as a fuel. In addition, biomass sludge contains a large amount of incombustible mineral impurities...
