Straw-wood chip honeycomb fuel and preparation method thereof

Abstract

Provided are a novel straw-wood chip honeycomb fuel and a preparation method thereof. The preparation method comprises the steps: crushing straw, grass wood chips and the like into a crushed materialwith the particle size of less than or equal to 5 mm, mixing calcium oxide with the crushed material according to a weight ratio of 3:(4-5), adding an appropriate amount of water, and stirring into acohesive state, preparing straw-wood chip honeycomb balls by a coal ball machine, air-drying, baking and charring in a sealed room at the temperature of 300 DEG C or less, spraying a potassium permanganate solution before leaving a factory, and air-drying. The straw-wood chip honeycomb fuel can be fully burned and has no pollution. A principle comprises that quick lime undergoes a reaction with water to produce slaked lime, the slaked lime calcium hydroxide removes grease from the straw and wood chips and undergoes a reaction with carbon dioxide in air to produce calcium carbonate, and the straw-wood chip honeycomb balls are hard and easy to store.

Description

technical field [0001] The invention relates to the field of development and utilization of straw and sawdust as new energy, in particular to a straw and sawdust honeycomb fuel and a preparation method thereof. Background technique [0002] Rural straw sawdust is developed and utilized as a new energy source. At present, there are mainly the following technologies: a. Straw sawdust granulation technology and equipment, but organic chemical binders need to be added during granulation, and after granulation, they are all solid rods, and the combustion is not sufficient. The emission of pollutants is increased due to the addition of organic chemical binders during combustion. b. Straw wood chip carbonization technology and equipment, equipment wear and tear, high failure rate, low output, high cost, difficult to promote. c. Technically, straw sawdust honeycomb production methods already exist, but the production principle remains at the backward level of using soil as a binder...

Problems solved by technology

[0002] Rural straw sawdust is developed and utilized as a new energy source. At present, there are mainly the following technologies: a. Straw sawdust granulation technology and equipment, but organic chemical binders need to be added during granulation, and after granulation, they are all solid rods, and the combustion is not sufficient. Increased emissions of pollutants due to added organic chemical binders during combustion

b. Straw wood chip carbonization technology and equipment, equipment wear and tear, high failure rate, low output, high cost, difficult to promote

c. Technically, straw sawdust honeycomb production methods already exist, but the production principle remains at the backward level of using soil as a binder. The production process has many ingredients and is complicated, and requires waste oil, sludge and other raw materials that are not easy to obtain
