Aluminum powder collecting and processing explosion-proof system and method

Abstract

The invention provides an aluminum powder collection and treatment explosion-proof system and method. The system comprises: a cyclone dust collector, which is provided with a dust collection air inletand a dust collection air outlet, and the air inlet is communicated with an aluminum powder dust production station through an air pipe; a rotational flow plate washing tower, which is provided witha washing air inlet, a washing air outlet, a liquid outlet and a spray pipe connector, wherein the washing air inlet is communicated with the dust removal air outlet, and the washing air outlet is connected with a fan; a sedimentation tank, which is provided with a water inlet pipe and a water outlet pipe, wherein the water inlet pipe communicates with the liquid outlet, and the water outlet pipecommunicates with the spray pipe connector; a filter press which is provided with a water inlet and a water return port, wherein the water inlet is connected with a sedimentation tank through a diaphragm pump, and the water return port of the filter press is connected with the sedimentation tank. According to the technical scheme, the dust concentration can be effectively reduced, the normal temperature state is kept, wetted dust can be recycled in a centralized mode, and the recycling safety is improved.

Description

technical field [0001] The invention belongs to the technical field of aluminum powder recycling equipment, and in particular relates to an explosion-proof system and method for collecting and processing aluminum powder. Background technique [0002] When some chemical factories produce aluminum-containing products, the aluminum powder and industrial dust in the pipes have not been treated, resulting in explosions, which seriously threaten the personal safety of workers. [0003] From the characteristics of aluminum powder, it can be seen that the concentration of aluminum powder is required for explosion. When the temperature and ignition point are satisfied at the same time, the explosion will occur, and the reaction between aluminum powder and water will generate hydrogen gas. If the wet aluminum powder is not properly handled and stored, there is also a risk of fire and explosion. . [0004] Therefore, it is necessary to design an explosion-proof system and method for c...

When the temperature and ignition point are satisfied at the same time, the explosion will occur, and the reaction between aluminum powder and water will generate hydrogen gas. If the wet aluminum powder is not properly handled and stored, there is also a risk of fire and explosion.
