Description
Technical Field
The utility model relates to the technical field of air-cooling and water-cooling, heat transfer and mass transfer condensers, in particular to a potential energy conversion spraying system for an evaporative condenser and a working method.
Background
The information in this background section is only for enhancement of understanding of the general background of the utility model and is not necessarily to be construed as an admission or any form of suggestion that this information forms the prior art that is already known to a person of ordinary skill in the art.
The evaporative condenser is a main heat exchange device in a refrigeration system, and the action principle of the evaporative condenser is as follows: the superheated high-pressure refrigerant gas discharged from the compressor in the refrigeration system passes through the condensing exhaust pipe in the evaporative condenser, so that the high-temperature gaseous refrigerant exchanges heat with the spray water and air outside the exhaust pipe. Namely, the gaseous refrigerant is gradually condensed into the liquid refrigerant from top to bottom after entering the discharging pipe from the upper opening. The super strong wind force of the matched induced draft fan enables the spray water to completely and uniformly cover the surface of the coil pipe, and the heat exchange effect is greatly improved by the aid of the wind force of the water. The spray water with the increased temperature is changed into a gaseous state from part, a large amount of heat is taken away by wind by utilizing the latent heat of vaporization of the water, water drops in the hot gas are intercepted by the high-efficiency dehydrator, and the water with the rest absorbed heat is scattered into the heat exchange layer of the PVC water spraying sheet, is cooled by the flowing air, has the reduced temperature, enters the water tank and then continues to circulate through the circulating water pump. The moisture evaporated into the air is automatically replenished by the water level regulator.
The inventor finds that the spraying mode adopted by the existing evaporative condenser cannot further improve the energy efficiency of equipment, and the spraying water affected by pressure can reduce the air suction effect of a fan when downward force is applied. Because of the spraying nozzle is in a large quantity, once the blockage happens individually, the coil pipe in the area right below cannot be cooled, and the performance of the equipment is seriously influenced. In order to achieve the energy-saving effect, the field equipment mostly adopts the operation of closing part of fans to reduce power consumption in the constant temperature stage after the full-load operation achieves the cooling effect, once the temperature rises, all the fans are opened to cool, the closed fans are close to the starting fans due to the fact that the temperature is increased, wind directly enters from fan openings to cause fan blade reversion, and once the field equipment is started, the reversed fan blades are subjected to the torsion of a positive motor, reverse inertia and continuous air suction power, and are subjected to huge acting force instantly to cause falling or breakage to cause accidents. In the past, the air chamber isolation method is adopted for prevention, but the cost is high, the effect is general, and accidents still cannot be avoided when the phenomenon of flowing backward due to strong wind occurs. Therefore, the water-driven fan blades are adopted for spraying operation, the water pump is utilized to pump water to form pressure and reversely push the small-angle fan blades to reversely rotate, the fan blades are enabled to rotate to generate upward wind, heat after evaporation is absorbed, spraying uniformity is guaranteed, and cold wind is guaranteed to be always from bottom to top. The comprehensive energy utilization rate of the equipment is improved, the power consumption of the equipment is reduced, and the equipment is low-carbon and environment-friendly.

the internal water is adopted to drive the fan to spray, and the water pressure is utilized to drive the fan to rotate to form upward wind, so that the effect of taking away hot wind by the external fan can be improved. By adopting transverse multi-hole rotary spraying, even if a single spraying hole is blocked, the spraying holes on other concentric circumferences can compensate water quantity to ensure evaporation and cooling. Because the field equipment only stops the fan and does not stop the water pump in the constant temperature period, the inner fan blade can provide continuous upward air, the air quantity is ensured to be sufficient and is provided for the fan in the starting state, air suction from other external fan ports is avoided, the original spray port is eliminated, the fan blade is replaced by the nylon fan blade, the bottom of the fan blade is provided with a customized water guide channel, water outlets are uniformly distributed in the channel according to the edge of the bottom of the fan blade, the water outlet angle under normal water pressure is within 15-35 degrees below the horizontal level, the preferred angle is 25-30 degrees, the angle and the radian waist line of the fan blade are smaller than those of the conventional fan blade, the proper air quantity is ensured to be provided after the conversion of the potential energy of the single fan blade, the water supply straight pipe is connected with the pressure main pipe by adopting a bearing, and the connection point is strengthened and fixed.

The evaporative condenser is smooth and not easy to scale due to the internal environment of the evaporative condenser, the connecting points are made of anticorrosive ceramic bearings, the operation is stable and reliable due to the fact that the connecting points are hardly influenced by external force, the air quantity of the evaporative condenser after the potential energy conversion spraying system is replaced is obviously improved under the test of conventional air-water ratio coefficients, the spraying effect is not greatly different, the maintenance frequency is reduced, and the reversion phenomenon of an external fan is effectively restrained. The existing spraying operation is carried out by adopting an internal water-driven fan, and the effect that the external fan takes away hot air can be improved by utilizing water pressure to drive the fan to rotate to form upward wind. The transverse multi-hole rotary spraying can ensure that even if a single spraying hole is blocked, the spraying holes on other concentric circumferential lines can also compensate water quantity to ensure evaporation and cooling. Because the field equipment only stops the air and does not stop the water pump in the constant temperature period, the internal fan blades can provide continuous upward air, the sufficient air quantity is ensured to be provided for the fan in the starting state, the air is not sucked from other external fan ports, the backward flowing air can be resisted, the fan blades are protected, and the accident is avoided.
