The invention discloses a multi-tube bundle rotational-flow precipitation separation device which comprises a tank body, a tubular hydraulic cyclone separator group, a water-in ring, a mud precipitation bucket, upper and lower filter plates, filler, a division cap and a division cone, wherein the tank body is mounted on a support leg, and the mud precipitation bucket is arranged inside; the tubular hydraulic cyclone separator group is uniformly arranged around the mud precipitation bucket; clone separation and gravity static precipitation separation of suspended solids are realized through the hydraulic cyclone separator and the mud precipitation tank respectively; the upper and lower filter plates are arranged at the middle part of the tank body; filter caps are uniformly distributed on the filter plates; the filler is arranged between the upper and lower filter plates; a water-out pipe is arranged at the upper part of the tank body; and the division cone and the division cap are arranged above the water-out pipe, and the suspended impurities and oil are guided and prevented from entering the water-out pipe. By adopting the device disclosed by the invention, the suspended solids in the water can be effectively separated, continuous operation can be realized, and the water output efficiency is improved while separation is guaranteed; and moreover, the suspended solids in various forms in the water are effectively disposed, separation is realized, and the water output effect is better.
