Embodiment Construction

[0012] On the basis of the existing biomass briquette fuel production process, the original ring die roll forming machine is changed to a double-roll forming machine or stamping forming machine that costs less than 1 / 10 of the same output, and the original screw feeder is changed to It is a double-shaft mixer and a simple sludge feeder is added to produce sludge biomass briquette fuel. The ratio of biomass powder to sludge with a water content of 80% is mainly controlled by the water content of the molding. The process is simple, the cost is low, the output is high, and the quality is good. If it is shaped nearby, it can be burned directly in the furnace; if it needs to be stored for a short time, it can be stabilized by adding lime. It is best to dry at 120-160°C to kill all microorganisms before leaving the factory for sale. If other binders are used, the biomass briquette can also be produced with a roll forming machine or a stamping forming machine.

Abstract

The invention relates to sludge biomass forming fuel, which belongs to the technical field of renewable energy development and carbon dioxide (CO2) emission reduction. A ring-mould rolling forming machine of the present biomass forming fuel is changed to a roll forming machine, sludge with moisture content of 80 percent in a sewage treatment plant is adopted as a forming caking agent, so the sludge biomass forming fuel can be produced. The yield can be improved by 30 times compared with that of original production technique, the investment and the cost can be reduced by 50 percent, the emission of the CO2 produced by the substituted coal can be reduced by millions of tons, the emission of sulfur dioxide (SO2) is reduced by millions of tons, the sludge can be completely burned, and the biomass waste can be completely utilized. The sludge biomass forming fuel has high yield and good quality and is low in cost; and the forming technique is simple and is easy to popularize and use. The technique also can be used for producing the biomass forming fuel through other caking agents.

Description

1. Technical field: [0001] The invention relates to energy utilization of urban sewage sludge (hereinafter referred to as sludge) and a biomass fuel molding process. Belonging to renewable energy development and CO 2 Emission reduction technology field. 2. Technical background: [0002] The annual production of biomass in the world is equivalent to 20 times of the current annual consumption of fossil energy by human beings, and it is called the fourth energy source. CO absorbed by plants during photosynthesis 2 CO emitted from combustion 2 can be flat. considered CO 2 Zero emissions, more popular today when low carbon emissions are required! 20 years ago, the world-renowned scientist who pointed out that human beings are causing the global warming and brought the issue of global warming into the political agenda issued another warning: CO in the global atmosphere 2 The content has exceeded the dangerous level! Call on human beings to "replace coal with firewood". He...
