Device for preventing particulate matter deposition in high-concentration slurry conveying process

The utility model discloses a device for preventing particulate matters from depositing in a high-concentration slurry conveying process. The device comprises a raw material tank, a stirrer, a circulating pump, a feeding pump, a reaction system and a gas system, a feeding pipeline of the raw material tank is connected with a raw material feeding port end, a stirrer is installed at the top end of the raw material tank, a nitrogen inlet end of the raw material tank is connected with a nitrogen pressurizing pipeline, a raw material conveying outlet of the raw material tank is connected with an inlet of a circulating pump, and an output end of the circulating pump is connected with a reaction and separation system through a pipeline. The inlet of the reaction and separation system is connected with the output end of the gas system. A large amount of slurry is returned to the raw material tank through self-circulation of the raw material tank so as to be fully mixed, conveying gas is additionally arranged behind t
