Continuous production system of biological powder for novel fireworks and production technology thereof

Abstract

The invention discloses a continuous production system of biological powder for novel fireworks and a production technology thereof. The continuous production system is controlled through an industrial program controller. The continuous production system comprises a physical processing part and a chemical processing part, wherein plant is used as raw materials. The production technology carried through the abovementioned production system comprises the following steps: crushing; nitrating through mixed acid; removing impurities such a sugar through alkali; washing with water; adding a stabilizing agent; and drying and forming to obtain a product. According to the continuous production system and the production technology, mechanical crushing and grinding, grading through screens with different meshes, continuous material adding, continuous neutralizing, water washing, separating and high-temperature vacuum carbonizing are carried out; the volume of used technical water is decreased; and meanwhile, the emission of wastewater is reduced; the industrial continuous production of plant cellulose is achieved; the production cost is saved; waste acid and wastewater can be recycled; the product replacing single-substrate powder is used for preparing luminescent fireworks and is high in burning performance and is hard to absorb moisture.

Description

technical field [0001] The invention specifically relates to a continuous production system and a production process of biological powder for producing smokeless gunpowder. Background technique [0002] With the environmental protection requirements and the development of high-performance, environmentally friendly and safe internal medicines for fireworks whipping, and the development of products in indoor and smoke-free forms, fireworks whipping production enterprises usually Using single-base powder as the main raw material, although single-base powder can reduce a large amount of smoke in fireworks products, but because single-base powder is controlled by the military, it is not suitable for civilian promotion, and the supply is limited and the price is high, which increases the cost of the product. Existing The supply quantity of smokeless medicine cannot meet the needs of fireworks whipping production; and the sensitivity of the single-base powder is low, and it contain...

[0002] With the environmental protection requirements and the development of high-performance, environmentally friendly and safe internal medicines for fireworks whipping, and the development of products in indoor and smoke-free forms, fireworks whipping production enterprises usually Using single-base powder as the main raw material, although single-base powder can reduce a large amount of smoke in fireworks products, but because single-base powder is controlled by the military, it is not suitable for civilian promotion, and the supply is limited and the price is high, which increases the cost of the product. Existing The supply quantity of smokeless medicine cannot meet the needs of fireworks whipping production; and the sensitivity of single base powder is low, it contains a small amount of nitroglycerin, which is very easy to explode

The use of plants as raw materials to produce smokeless cellulose instead of nitrocellulose to produce smokeless gunpowder has been reported and studied. The existing research on the use of plants to prepare cellulose powder for fireworks is basically concentrated on the alternative application of cellulose powder, while fireworks used Due to the limitation of production conditions, the preparation process of cellulose powder basically adopts artificial small-batch production process. In the existing production process, after the raw materials are crushed, the plant raw material particles with different particle sizes have not been classified, that is, the crushed mixture is directly added The reaction kettle is used for nitration treatment. During the reaction process, due to the uneven particle size of the material added to the reaction kettle, the amount of acid and alkali used in the chemical treatment process is not uniform, resulting in waste of raw materials and the final product. Decomposition of plant matter due to uneven chemical treatment Incomplete, the product has poor combustion performance and is easy to absorb moisture; during the entire reaction process, the labor intensity of the workers is high, the workshop environment is poor, and the chemical treatment process is treated by acid treatment, water washing, alkali treatment, and separation processes. If a large amount of waste water, waste acid, waste alkali, and waste gas are not treated in time, it will waste raw materials, manpower and pollute the environment
