Rotary cooler

Abstract

The invention discloses a rotary cooler. The rotary cooler is of a single column and connection rod structure and comprises a connecting thread head, a water collection port, a water-dispersing conical head, a rotary impeller and a bottom water disperser, wherein a thread is arranged at one end of the connecting thread head, the other end of the connecting thread head is a connection end, the connection end of the connecting thread head is connected to the water collection port, the water collection port is connected to the water-dispersing conical head, the rotary impeller is arranged on a conical head body of the water-dispersing conical head, the bottom water disperser is arranged at the bottom end of the rotary impeller, water flow impacts a water-guiding conical body of the water-dispersing conical head so as to be guided and separated, and therefore the separation effect of a separating conical body can be improved, and the centrifugal force and the splattering speed of water can be increased. According to the rotary cooler, the head falling problem, the breakage problem and the filler washing-off problem of a splashing device can be solved; damage caused by freezing of a water tower in winter can be reduced or eliminated; auxiliary power can be reduced; the coal consumption can be lowered; and the maintenance cost can be lowered, the water distribution uniformity can be improved, the water outlet temperature of the water tower can be lowered, the exhaust steam pressure of a turbine can be lowered, and the coal consumption of power generation can be reduced.

Description

technical field [0001] The invention relates to the field of water cooling towers in thermal power stations, in particular to a rotary cooler. Background technique [0002] The uniformity of spraying water has a great influence on the cooling of the cooling tower. If a part of the filling is not covered with water, then this part will not be able to cool. The air passing through the filling area does not participate in the heat exchange process, and the heat exchange efficiency of the tower will inevitably decline. For the impact of natural draft cooling towers, in addition to the above, it is also possible to reduce the ventilation rate of the cooling tower. [0003] If the filler can be sprayed with circulating water, but the uniformity of water distribution is not good, there will be heavy water area, light water area and anhydrous area, which will reduce the efficiency of the cooling tower. [0004] Experiments show that: for a 4000m² water tower, if the non-uniform co...
