AI Technical Summary
In chemical production, after dissolving the raw materials in the raw material tank and directly sending them to the reactor, there are large particles or impurities that are not sufficiently dissolved, which affects the reaction efficiency and sufficiency. The direct dripping of the raw material solution is not conducive to sufficient contact with the solution in the reactor, resulting in insufficient reaction and low rate.
A dissolution tank atomization feeding system is designed, including dissolution tank, feeding pipeline, primary and high-efficiency filter, back-blowing cleaning pipeline and atomization spray head. The filter branch and back-blowing cleaning pipeline are used to ensure the filtration and cleaning of the raw material solution, and then the solution is atomized and fed through the atomization spray head to achieve full contact with the solution in the reactor.
Through filtration and atomization treatment, the particle impurities in the dissolving tank are effectively removed, the feeding efficiency is improved, the reaction sufficiency and efficiency are ensured, corrosion and clogging are prevented, and the safety and stability of the system are improved.
