Problems solved by technology

However, this only solves a small amount of solid waste from biomass power plants. Due to the lack of effective utilization channels and sales markets for ash, in most cases, it is generally used for primary treatment such as landfill, or randomly piled up. Such extensive treatment methods not only It has no benefit, occupies land resources, causes the ecological chain of nutrient elements necessary for plant growth to break, and also restricts the development of biomass power generation, and is increasingly becoming a burden on the economy and the environment

[0034] (3) Mix 7Kg of No. 2 ash, 3Kg of No. 3 ash and 3Kg of P.O 42.5 cement. Stir with a stirrer at a speed of 120 r / min for 3 minutes at room temperature, and add 3.9 L after stirring for 1 minute. of tap water, and then stirred at a speed of 70 r / min for 1.5 min to obtain a bottom material; meanwhile, mix 10Kg of No. 3 ash and 3Kg of P.O 42.5 cement evenly according to the same steps above to obtain a fabric;

[0035] (4) Place the mold on a vibrating table with an amplitude of 3 mm....

Embodiment 2

[0043] A preparation method for biomass ash bricks, comprising the steps of:

[0044] (1) Sieve the biomass ash to obtain No. 1 (effective particle size 10-30mm), No. 2 (effective particle size 5-10mm) and No. 3 (effective particle size 0.5-0.8mm) biomass material ash;

[0045] (2) Use tap water to clean the three kinds of biomass ash and slag. After the first cleaning for 20 minutes, replace the tap water, and then wash after the second immersion for 10 minutes. The cleaned ash and slag are weathered and dried under natural conditions;

[0046] (3) Mix 3Kg of No. 1 ash, 4Kg of No. 2 ash, 3Kg of No. 3 ash and 3Kg of P.O 42.5 cement, and stir for 3 minutes with a stirrer at a speed of 120 r / min at room temperature. When stirring for 1 minute, add 3.9 L of tap water, and then stir at a speed of 70 r / min for 1.5 minutes to obtain a base material; at the same time, mix 10Kg of No. 3 ash and 3Kg of P.O 42.5 cement according to the same steps as above to obtain a fabric;

Abstract

The invention discloses a biomass-ash-residue brick as well as a preparation method and application thereof. Biomass ash residues are used as raw materials; the biomass-ash-residue brick is obtained after the biomass ash residues with different particle sizes and cement are mixed and agitated by adopting a certain matching ratio, an obtained mixture is molded, and the molded mixture is maintained. The problems that the utilization rate of the ash residues from a biomass power plant is currently low and the resource waste and the environmental pollution are caused are solved; a feasible resource utilization path is provided for the biomass ash residues of the power plant; meanwhile, the biomass-ash-residue brick is prepared by adopting a sintering-free technique, and has the advantages of being free from sintering, free from high temperature and high pressure, short in treatment period, good in treatment effect, and the like. The compression strength of the biomass-ash-residue brick provided by the invention can meet requirements in the GBT17431.1-2010; meanwhile, the biomass-ash-residue brick also conforms to the GB5085.3-2007 standard; the leachability of heavy metal is extremely low; the biomass-ash-residue brick has no harmful elements, has no ecological risks, and belongs to an environment-friendly product.

Description

technical field [0001] The invention belongs to the field of solid waste comprehensive treatment and resource utilization, and specifically relates to a biomass ash brick material with certain compressive strength and environmental friendliness, a preparation method and application thereof. Background technique [0002] With the shortage of fossil fuels and the increasingly serious environmental pollution, the development and utilization of renewable energy, especially biomass energy, has gradually attracted people's attention. Biomass combustion technology has been widely used in power plants. my country is a large agricultural country with abundant biomass reserves. Straw alone has as much as 700 million tons. The short-term development potential is about 500 million tons of standard coal, and the long-term potential can reach 1 billion tons of standard coal. With the implementation of the "Twelfth Five-Year Plan" released in 2012, by 2015, the installed capacity of biomas...
