Description

Energy-saving flow self-adaptive spray head of cross flow type cooling tower Technical Field The invention relates to the technical field of cross flow cooling tower spray heads, in particular to an energy-saving flow self-adaptive spray head of a cross flow cooling tower. Background In the existing cross-flow cooling tower application, the energy-saving flow self-adaptive spray head has become a core execution component of the water distribution system. At present, the common flow self-adaptive spray head of the cooling tower mainly comprises two types, namely a multi-stage water inlet control type spray head, a plurality of water inlets are formed at different heights of the spray head based on the logic of the water level, the water quantity entering the spray head is accurately controlled by automatically switching water inlet paths, the problem of insufficient water quantity of the end spray head at low water level is solved, and the flow self-adaptive spray head is an open gradual change type flow passage type spray head, and the flow self-adaptive spray head is throttled by means of geometric shapes, such as a vertical strip-shaped opening extending along the height direction is formed on the side wall, or a V-shaped water inlet is formed on a water guide device, and the actually-passing sectional area of water flow is automatically changed along with the change of the water level or the pressure, so that the flow is regulated. The structure does not need external power, is driven by water completely, and is an absolute mainstream for reforming and applying the cooling tower at present. However, during actual long-term operation, the circulating hot water inevitably contains fine impurities such as microbial slime, silt, algae, etc. These impurities tend to gradually deposit at the V-shaped inlet or the narrow flow passage of the nozzle, resulting in a reduced effective cross-sectional area of the inlet and even complete blockage of the inlet in severe cases. Although the prior nozzle structure has realized the self-adaptive flow regulating function of hydraulic drive, an effective interception and online cleaning mechanism for the inlet water impurities is generally lacking. Once the water inlet is blocked, the actual water yield and water distribution uniformity of the spray head are greatly reduced, so that the heat exchange efficiency of a filling area is affected, the energy consumption of a fan and a water pump is increased, and even the cooling tower is forced to stop for manual cleaning or spray head replacement. Therefore, how to effectively solve the problems of deposition and blockage of the inlet water impurities and realize convenient maintenance and long-acting operation of the filtering structure while maintaining the flow self-adaptive adjustment capability is a technical problem to be solved in the technical field of the current cross-flow cooling tower spray heads.
