Environment-friendly bricks prepared from waste energy-saving lamp residue and manufacturing method thereof

Abstract

The invention relates to environment-friendly bricks prepared from waste energy-saving lamp residue and a manufacturing method thereof. The manufacturing method is characterized by comprising the following steps of: mixing raw materials of waste energy-saving lamp residue, waste carbide residue, flyash, portland cement, calcium oxide, calcium sulfate, sodium carbonate, a polycarboxylate high range water reducer, sodium sulfate, calcium formate, a Li high polymer heavy metal trapping agent, water and the like, stirring into a humid state by adopting a double shaft mixer, and extruding and molding through mechanical vibration under the pressure of 25-30MPa to manufacture environment-friendly green bricks prepared from the waste energy-saving lamp residue; and performing steam curing on the molded environment-friendly green bricks by using a still kettle, raising the temperature for heating for 2 to 3 hours, keeping the temperature of between 95 and 100DEG C for 5 to 8 hours, and naturally reducing temperature for 1 to 2 hours to obtain the environment-friendly brick products. The raw materials also can be prepared into hollow building blocks and sidewalk and square bricks in different specifications; and the products have the advantages of light weight, high strength, no pollution, low cost and good benefit.

Description

technical field [0001] The invention relates to an environmentally friendly brick produced from the waste residue of waste energy-saving lamps. Specifically, it is produced by using the waste residue of waste energy-saving lamp tubes and calcium carbide waste residue after crushing, sorting, and magnetic separation to remove waste metal as the main raw material. The environmentally friendly bricks belong to the field of waste treatment. [0002] The invention also relates to a manufacturing method of waste energy-saving lamp waste slag environmental protection bricks. Background technique [0003] In order to strengthen energy-saving and emission-reduction measures, my country will phase out incandescent lamps, promote special planning for energy-saving lamps, accelerate the transformation of incandescent lamp manufacturers in my country, and produce and popularize energy-saving lamp planning projects. In the 10 years after the implementation of the project, my country is e...

Problems solved by technology

However, in the large-scale production of energy-saving lamps, a large number of discarded energy-saving lamps and waste lamps damaged after use will inevitably be produced, and each energy-saving lamp contains an average of 0.25 mg to 0.5 mg of mercury. At present, my country The treatment methods for waste energy-saving lamp tubes are mixed with other garbage and sent to landfill for landfill treatment. If the mercury content of a waste energy-saving lamp tube is immersed in the ground, it will cause 180 tons of water pollution.

Among the 150 to 200 million energy-saving lamps to be promoted nationwide in a year, a large amount of mercury-containing waste from waste energy-saving lamps will flow out and immerse into the ground, which will form a pollution potential of 3 to 4 billion tons of water sources, which will be released from landfills. Part of the mercury will also enter the atmosphere in the form of methylmercury vapor. This pollutant is more likely to enter the respiratory tract and food chain, and will also cause a wider range of air pollution; The light gray fine particle suspension sedimentation waste produced in the process of manufacturing polyvinyl chloride and vinyl acetate will also cause environmental pollution and waste of resources
