Straw briquetting formula and method for preparing same

Abstract

The invention relates to a straw briquetting formula and a method for preparing the same. The method comprises the following steps: 1) crushing 70 to 90 parts by weight of tobacco straw and 5 to 15 parts by weight of bark, so that the lengths of the tobacco straw and bark are less than 40 mm; 2) mixing the crushed tobacco straw and bark with 5 to 15 parts by weight of clay, putting into a blender, pouring 5 to 12 parts by weight of water into the blender, mixing and stirring until a semi-solidification state is formed; 3) allowing a mixture obtained in step 2) to enter a straw briquetting machine through a feed port to be briquetted, and regulating the pressure to be more than 480 MPa, wherein the straw briquette density is 1.18 g / cm<3>, and the straw briquette curing molding degree is 99%; drying the straw briquette until the straw briquette moisture content is 15 to 20% to obtain a straw briquette. The straw briquetting formula and the method for preparing the same provided by the invention have the characteristics of convenience in transport and storage, high molding degree, small size, good combustibility, avoidance of wasting of resources, reduction in production cost, broad market prospects and the like.

Description

technical field [0001] The invention relates to the field of fuel, in particular to a straw briquette formula and a method for preparing the straw briquette. Background technique [0002] With the progress and development of society, people use more and more natural resources. However, with the continuous reduction of petrochemical resources, air pollution caused by coal burning, and environmental problems such as global warming have intensified, people have also begun to deeply The method of thinking and solving problems, the recycling and reuse of resources has become an important issue facing my country's sustainable development. Serious energy and environmental problems are the main solution. [0003] However, the current society generally uses coal as fuel. When coal is burned, nitrogen does not generate heat, but is transformed into nitrogen oxides and ammonia at high temperatures, which are separated out in a free state. Sulfur, phosphorus, fluorine, chlorine and arse...

On the other hand, a large amount of groundwater resources have leaked into mines and been discharged due to the destruction of coal-measure strata. Less than 20% of these water resources have been purified and utilized, causing new pollution to the surrounding environment of the mining area.

When the raw coal is washed, a large amount of slime water is also discharged to pollute the soil vegetation and river water system, causing incalculable damage to the ecological environment
