The combustion performance of sludge alone is poor. When waste straw is added to combustion together, the comprehensive combustion characteristic index increases and the combustion performance is improved. It proves that the mixed combustion of sludge and biomass waste is a good way for sludge resource utilization. In order to solve the problems of environmental pollution and energy shortage in today's society, the technology of mixing sludge and agricultural straw to prepare alternative fuels came into being. This article will deeply discuss the principle, preparation process and application prospect of this technology.
The principle of mixing sludge and agricultural straw to prepare alternative fuels
Sludge is organic waste produced during municipal sewage treatment, while agricultural straw is the residue left after harvesting crops. These two types of waste are often viewed as burdens in conventional treatment processes, but they are actually rich in organic matter and cellulose. Hybrid alternative fuel technologies take advantage of the high carbon content and potential energy value of these wastes by converting them into solid fuels through physical or chemical processing.
Preparation Process
The process of preparing sludge and agricultural straw mixed alternative fuel includes the following main steps:
- Raw material preparation: collect municipal sludge and agricultural straw, conduct preliminary treatment and dry to reduce moisture content.
- Mixing: The sludge and agricultural straw are mixed according to a certain ratio to ensure that the mixture has better molding performance and energy value in the subsequent treatment.
- Processing and granulation: The mixture is sent to processing equipment for granulation and molding. The mixture is pressed into solid pelletized briquettes, usually using a high pressure molding machine or pelletizing equipment.
- Heat treatment: The molded fuel is heat-treated at high temperature to improve its combustion performance and calorific value and reduce its moisture content.
Technical advantages and application prospects
The technology of mixing sludge and agricultural straw to prepare alternative fuels has the following advantages and application prospects:
- Energy recovery: This technology can convert waste sludge and straw into renewable fuels, saving energy resources and reducing dependence on fossil fuels.
- Environmental protection and emission reduction: The combustion process of briquette fuel is relatively clean, which reduces exhaust emissions and environmental pollution, and helps to improve air quality and reduce greenhouse gas emissions.
The technology of mixing sludge and agricultural straw to prepare alternative fuel is an innovative technology with important environmental protection and energy value. However, the R&D and improvement of technology and equipment in the preparation process need to be further strengthened to improve the quality and economy of alternative fuels.
