Problems solved by technology

Due to the low price of the product, it is impossible to use the high-cost full nitrogen protection and ultrafine pulverization process
Because sulfur is flammable and explosive, the sulfur dust generated during production is extremely easy to scatter in the air, which will not only cause disturbance to the staff, but also affect their health. burst
Moreover, the existing production process does not have any safeguards for the lifting and transportation of aluminum powder, magnesium powder, sulfur and the recovery of dust, which is extremely prone to explosion
Moreover, the current technology uses cheap high-speed pulverizers in the pulverization system, and there is no iron removal device for the feed. When pulverizing, the static sparks generated by iron will collide and explode. The wind brought into the rear system, causing static sparks to explode
Therefore, there are hidden dangers of impact explosion and electrostatic explosion in the existing production process

Abstract

The invention discloses an explosion-proof rapid grinding production technology, which includes the production and processing of inflammable and explosive products such as sulfur powder. The beneficial effects of the present invention are: the import of raw materials adopts strong magnetism to remove iron to avoid spark explosion caused by the impact of the system after the iron enters; all the equipment in contact with the inflow of raw materials and the outflow of finished products are made of non-metallic materials or non-metallic linings, Avoid the explosion of friction sparks with metals; for the grinding process of raw materials, use non-metallic lining grinding equipment with a lower grinding speed and water cooling during the grinding process to avoid high-temperature explosions, and use the system to vacuumize and fill nitrogen for grinding Protection, and a pressure relief device is used to avoid operating accidents caused by excessive pressure. A dust recovery device is installed in the process device to ensure that the operating environment meets occupational hygiene requirements. In addition, the dust recovery device adopts negative pressure suction, and the conveying pipe adopts atomization humidification and water washing for dust removal to avoid dust explosion.

Description

technical field [0001] The invention relates to an explosion-proof fast grinding production technology. It is suitable for the technical field of production of flammable and explosive products such as sulfur. Background technique [0002] Sulfur is also known as sulfur, colloidal sulfur, and sulfur block. Appearance is pale yellow brittle crystal or powder with special odor. Sulfur is insoluble in water, slightly soluble in ethanol and ether, and easily soluble in carbon disulfide. As a flammable solid, sulfur is mainly used in the manufacture of dyes, pesticides, matches, gunpowder, rubber, rayon, etc. Sulfur is an important species of inorganic pesticides. The product is yellow solid or powder, with obvious odor and can be volatilized. Sulfur aqueous suspension is slightly acidic, insoluble in water, and reacts with alkali to form polysulfides. When sulfur burns, it emits a blue flame, and sulfur dioxide gas is produced along with the combustion. Inflammable and exp...
