Photocatalytic device for degrading pollutants in mineral admixture

Abstract

The invention provides a photocatalytic device for degrading pollutants in mineral admixtures, which comprises a treatment tank, a photocatalytic component is arranged inside the treatment tank, a gas guide component is arranged outside the treatment tank, and the gas outlet end of the gas guide component is connected with a gas transmission component; the gas guide component comprises a gas guide sleeve arranged on the outer surface of the treatment tank in a sleeving manner and a feeding mechanism arranged outside the gas guide sleeve; the gas transmission component comprises a high-pressure fan connected with the gas outlet end of the gas guide sleeve, a gas outlet pipe connected with the gas outlet end of the high-pressure fan, and a plurality of gas return pipes which are fixed on the gas outlet pipe and extend to the lower surface of one end of the treatment tank; the photocatalytic component comprises a feeding mechanism arranged at the top end of the treatment tank, a discharging mechanism arranged at the bottom end in the treatment tank, and a rotary catalytic mechanism arranged between the feeding mechanism and the discharging mechanism. According to the invention, the catalyst can be guided to be in full contact with the admixture and flue gas generated after the admixture falls into the treatment tank, so that the treatment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of preparation of mineral admixtures, in particular to a photocatalytic device for degrading pollutants in mineral admixtures. Background technique [0002] Mineral admixtures are a very important raw material in the field of civil engineering. Mineral admixtures specifically refer to inorganic mineral fine powders that can improve the performance of fresh concrete and hardened concrete when preparing concrete. [0003] The existing patent (application number: 201921698993.9) proposes a photocatalytic reaction device for the degradation of organic pollutants. Cooling pipeline, upper cover, upper movable seat, connecting shaft, return hole, connecting hole, water outlet pipe, return pipe, water inlet pipe, cooling water chamber, lower movable seat, tank body 1, tank body 2, motor, sealing ring and circulation pump. The utility model has the advantages of reasonable and simple structure, low production cost...
