Embodiment Construction

[0022] The present invention will be further explained below in conjunction with the drawings and specific implementations:

[0023] 1. The preparation method of clean and environmentally friendly straw briquette of the present invention includes the following steps:

[0024] 1) Cut the wheat straw into wheat straw grains, crush the corn stalks into corn stalk grains to ensure that the particle size is less than 3 mm, then mix the wheat straw grains and corn stalk grains in a certain ratio, and press the mixed wheat straw and corn stalks into Straw block; the grain length of the wheat straw grains is 1 mm to 3 mm, the grain length of the corn stalk grains is 1 mm to 3 mm, and the mixing ratio of the wheat straw grains and the corn stalk grains is 3:5.

[0025] 2) The coal slime and finely washed coal, gangue, and straw materials are evenly stirred by a mixer and then added with additives for crushing and screening together to ensure that the particle size of coal slime is below 3mm, ...

Abstract

The invention discloses clean and environment-friendly straw briquette coal and a preparation method thereof. The environment-friendly straw briquette is processed by adding finish-washed coal, coal slime, gangue, additive and a binder into straw materials and mixing through scientific preparation under action of a certain pressure. The clean and environment-friendly straw briquette coal provides a clean and environment-friendly biological energy source. Compared with raw coal, the clean and environment-friendly straw briquette coal is good in gas permeability, higher in heating efficiency and more sufficient in combustion, so that pollution on environment is reduced.

Description

Technical field [0001] The invention designs the field of briquette production, and specifically relates to a clean and environmentally friendly straw briquette and a preparation method thereof. Background technique [0002] 1. The impact of coal mining and processing on the environment. my country has abundant coal resources and is China's main energy source. However, the current development and utilization of coal has put tremendous pressure on the environment. According to current statistics, the national gangue stock has reached 3 billion tons, and the utilization rate is only 36.2℅. The gangue naturally emits a large amount of smoke and dust, sulfur dioxide, carbon monoxide, hydrogen sulfide and other harmful gases. During the washing process of coal, there is a large amount of coal slime. Produced and formed a large amount of dust, causing serious pollution to the environment. [0003] 2. A large amount of pollutants emitted by coal burning cause serious pollution to the env...
