Problems solved by technology

[0002] At present, there are a large number of discarded distiller's grains that need to be disposed of after brewing in domestic liquor companies. If the distiller's grains are allowed to accumulate without being treated or disposed of in time, the discarded distiller's grains after acid rot will seriously pollute the surrounding soil, water and air, and are easy to breed Harmful bacteria and mosquitoes etc.

Abstract

The invention relates to a preparation method for a liquor residual biomass fuel rod. The preparation method comprises steps: first, acid-base neutralization is carried out, quicklime is mixed with materials and the pH value is adjusted to 6-8; second, hot air drying is carried out, fresh waste residuals are dried by hot air generated from flue tail gases discharged by waste residual boilers or high-temperature steam generated from waste residual boilers through a heat exchanger, and the flue tail gases discharged by waste residual boilers are subjected to purification treatment; third, hot pressing molding is carried out, and pressing molding is carried out with a molding pressure of 4-8 MPa and with a water content of 5-15% at the temperature of 140-180 DEG C; fourth, packaging and warehousing are carried out. The beneficial effects of the method are that, waste residuals are prepared into biomass fuels; compared with raw coal, pollution and destroy to the environment can be reduced greatly, and the purposes of energy saving and emission reduction can be achieved effectively; compared with straw biomass fuels, the prepared biomass fuels have uniform particles with small diameters, need not early-stage crushing and processing, are easy to be molded, contain a lot of rice hull combustible components, and have high combustion utilization values.

Description

technical field [0001] The invention relates to the field of energy, in particular to a method for preparing distiller's grain biomass fuel rods. Background technique [0002] At present, there are a large number of discarded distiller's grains that need to be disposed of after brewing in domestic liquor companies. If the distiller's grains are allowed to accumulate without treatment or if the treatment is not timely, the discarded grains after acid rot will seriously pollute the surrounding soil, water and air, and are easy to breed Harmful bacteria and mosquitoes etc. [0003] As a worldwide problem, the energy problem has attracted more and more attention from the world. The main source of energy in the world is petroleum, but petroleum is a non-renewable resource. With the continuous exploitation of petroleum, mankind is facing the severe challenge of petroleum and energy crisis, because the proven reserves of petroleum on the earth are about to reach the limit.
