Multifunctional water collection tank for high water collection cooling tower

Abstract

The invention discloses a multifunctional water collection tank of a high-order water-saving cooling tower. The multifunctional water collection tank comprises a water tank body, a connection flange, notch reinforcement ribs, an outwards protruded reinforcement rib, a bearing and lifting steel band and a transverse lifting rod, wherein the water tank body comprises a water collection tank body and an upper arc drainage side plate; the upper arc drainage side plate is arranged above one side wall of the water collection tank body; the bearing and lifting steel band covers the outer surface of the water collection tank body and is fixed by and covered with the notch reinforcement ribs; two ends of the transverse lifting rod are fixedly mounted at combination parts of the notch reinforcement ribs and the bearing and lifting steel band. The notch reinforcement ribs and the outwards protruded reinforcement rib are arranged on the outer side surface of the water tank body, so that demolding is facilitated, and the overall strength of the water tank body is improved; the bearing and lifting steel band and the notch reinforcement ribs are additionally arranged at the lifting position, so that the weight of the water collection tank is concentrated on the bearing and lifting steel band and the notch reinforcement ribs; the inner side surface of the upper arc drainage side plate is smooth, so that smoothing of air flow is guaranteed, and the problems in the prior art are ideally solved.

Description

Technical field: [0001] The invention relates to a water-saving device applied to a power plant, in particular to a water collection tank of a high-level water collection cooling tower. Background technique: [0002] In the cooling tower of the power plant, the hot water cooled by the turbogenerator is input into the central shaft through the head pump, sprayed to the cooling packing layer through the cooling water distribution pipe system and spraying device, and finally enters the sump, and then is pumped by the head pump. The suction is used for the cooling of the steam turbine generator to realize the circulation and cooling utilization of the cooling water. [0003] In order to reduce the cooling cost of the turbogenerator and save energy consumption, the applicant participated in the high-level water collection cooling technology test of the cooling tower of the power plant, and added a water interception and diversion device under the cooling packing layer to flow int...

AI Technical Summary

Problems solved by technology

[0006] In the high-level water collection cooling tower, the water collecting tank of the water interception and diversion device is a very important part. For the smooth transition of the water flow, the bonding strength between the sump and the sloping plate and the strength of the sump itself to withstand the water flow are all crucial. In actual work, there are the following problems: 1: Due to the huge area of ​​the sump , usually suspended under the filler by a suspension device, long-term suspension and long-term water splashing under a certain pressure make the suspension part of the sump unable to withstand the water pressure and cause cracking or deformation; In the existing forming process, due to the overall shape of the sump, reinforcing ribs are provided inside the sump, so that the sump can further enhance the strength of receiving water flow during work, but because the existing reinforcing ribs are all set in the sump The inside of the sink, which makes the processing very difficult, is not conducive to the final stripping; 3: The sump also plays a certain role in drainage, that is, the bend at the connection between the upper end of the sump and the deflector inclined plate forms an air flow in the tower For guidance, when the suspension part of the sump is deformed, it will affect the bend at the upper end, making it affect the flow performance of the airflow
