The utility model discloses a kind of desulfurizer mixing devices with helical propeller, belong to flue gas desulfurization field, including mixing tank, the mixing tank includes straight cylinder cavity and conical cavity, the straight cylinder cavity is integrally formed with conical cavity, the mixing tank inside is provided with helical propulsion mechanism for material mixing, the mixing tank top is provided with feed inlet, the utility model structure is relatively simple, maintenance is convenient, by the helical propulsion mechanism of being set, by the rotation of helical blade, cooperate with the baffle of being set, rapidly form a severe, dead corner-free large-scale axial circulation flow field in whole mixing tank, and shear force, so that solid particles can be quickly wetted and dispersed by liquid, cooperate with the rotation of stirring blade and bottom scraper, by the rotation of bottom scraper, the solid particles possibly settled or accumulated in conical cavity inner wall dead corner place are scraped, cooperate with the rotation of stirring blade and stirring, it is favorable to improve the quality and efficiency of mixing.

The application discloses an ecological fishery breeding system sewage circulating treatment device, and relates to the technical field of sewage treatment.The device comprises a separation tank, a horizontal partition plate is arranged in the separation tank, and the inside of the separation tank is divided into an upper stirring chamber and a lower sedimentation chamber; a stirring mechanism is arranged in the stirring chamber, and the stirring mechanism comprises a vertically arranged stirring shaft and stirring blades arranged on the stirring shaft; the top end of the stirring shaft penetrates through the top of the tank and is connected with a driving mechanism; the bottom end of the stirring shaft penetrates through the horizontal partition plate and is rotationally connected with the horizontal partition plate; a wastewater inlet and a flocculant adding port are arranged on the top of the separation tank and are communicated with the stirring chamber; and the separation tank further comprises a drainage mechanism, which is arranged on the stirring shaft.The ecological fishery breeding system sewage circulating treatment device can promote chemical flocculation through physical stirring, can utilize an independent static space for physical sedimentation, and can automatically connect the two stages through centrifugal force, so that the efficient cooperation of physical and chemical multistage treatment is realized.

The application relates to the technical field of tailing treatment, in particular to a high-mudding copper-nickel ore dressing tail water treatment, recycling and recycling system and process, wherein the high-mudding copper-nickel ore dressing tail water treatment, recycling and recycling system comprises a crushing module, a grinding module and a flotation module; after minerals are separated from ore slurry, the flotation module is used to obtain flotation tailings and flotation concentrates, and the flotation tailings and the flotation concentrates are respectively transported to an A-type water treatment submodule and a B-type water treatment submodule; the A-type water treatment submodule is used to receive the flotation tailings, and sequentially passes through a sedimentation unit and a dosing unit to carry out solid-liquid separation and water purification treatment; overflow water obtained through the treatment is used as A-type clarified water and is returned to the crushing module, the grinding module and the flotation module to supply water; and bottom flow water obtained through the sedimentation is transported to a tailing pond to carry out natural sedimentation, so as to recycle C-type clarified water to supply water to the flotation module. According to the application, the comprehensive recycling utilization rate of the ore dressing tail water is improved by combining tailing three-stage series deep clarification and tailing pond backwater reuse.

The utility model discloses a kind of silicon powder recovery devices in industrial silicon furnace flue gas, including equipment base, separator tank, smoke inlet and gas outlet, the inside of the separator tank is movably connected with multiple groups of adjusting mechanism for changing flue gas flow rate, the adjusting mechanism includes fixedly connected on the inner side wall of separator tank fixed pivot, the fixed pivot is movably connected with spoiler through fixed link, and the spoiler is in conformity with the inner diameter of separator tank, the end of the spoiler is movably connected with piston;Through fixed link and the spoiler of pivot connection, and piston is movably connected with the end of spoiler and penetrates tank body, when flue gas quantity is larger and flow rate is too fast, tank pressure rises and pushes piston to move out, drives spoiler to rotate to tank wall, expands flue gas flow range to reduce flow rate, prolongs flue gas residence time, makes silicon powder fully settle.
