Description

A non-mechanical transmission jet spray adjustable cooling device

technical field

The utility model belongs to the technical field of jet ventilation and cooling, in particular to an adjustable cooling device without mechanical transmission jet spray.

Background technique

At present, the existing technologies commonly used in the industry are as follows: the commonly used open counterflow cooling towers at home and abroad mainly include traditional mechanical ventilation packing cooling towers, traditional mechanical ventilation filling spray cooling towers, traditional hydraulic fans without filling gravity return water secondary Spray cooling tower.

The traditional mechanical ventilation packing cooling tower is forced by an electric mechanical fan, and the packing cloth is used for liquid mass transfer. The mechanical fan is driven by electricity, with mechanical transmission deceleration parts and packing structure. There are several major problems: ①Continuous energy consumption, because the fan is driven by the motor; ②Regular maintenance is required, and replacement is due, because there are mechanical fan transmission and deceleration components in the core structure; ③Reliability continues to decline, due to the service life of mechanical transmission bearing components, etc. Restrictions, with long-term continuous operation, the core mechanical fan deceleration drive system will have reliability problems such as increased vibration and failure of operation balance; ④Regular maintenance and replacement are required, and the cooling effect will gradually decrease, because the core structure contains a packing structure, with long-term continuous operation , algal growth, dust accumulation, etc., the filling gap will gradually be blocked, resulting in a decline in cooling efficiency, so it needs to be cleaned, maintained and replaced regularly.

The traditional mechanical ventilation without filler spray cooling tower is forced by the electric fan, and the spray mass transfer is concentrated vertically upward by the fixed nozzle group, and the mechanical fan is driven by electricity, and there is a mechanical transmission deceleration part. There are several major problems: ①Continuous energy consumption, because the fan is driven by the motor; ②Regular maintenance is required, and replacement is due, because there are mechanical transmission deceleration parts in the core structure; ③Reliability continues to decline, due to the service life limit of mechanical transmission bearing components , with long-term continuous operation, the core mechanical fan deceleration transmission system will have reliability problems such as increased vibration and failure of operation balance; ④The flow resistance is large and the cooling performance is poor, because the nozzle components are concentrated and sprayed vertically upward, and the spray flow is concentrated in the center of the tower , resulting in a large ventilation resistance at the bottom of the tower and a large reduction in the intake of cold air, which ultimately leads to poor cooling performance of the whole tower; and other actual needs, which is not conducive to industrial application.

The traditional hydraulic fan has no filler and gravity return secondary spray cooling tower. It is a hydraulically driven mechanical swirling atomization propulsion fan device to force suction, atomization and mass transfer. The primary atomization cooling water is cooled by gravity return secondary spray. There are several major problems: ① There is still the problem of continuous decline in reliability. Because the core structure of the swirling atomization propulsion fan device is still a mechanical transmission component, it is limited by the service life of the transmission bearing components. With long-term continuous operation, the rotating bearing components will continue to Wear and tear, dynamic balance failure, reliability will gradually decline, resulting in operational failure, resulting in downtime; ② still need regular maintenance, due replacement, because the core structure swirling atomization propulsion fan device is still a mechanical transmission part, its running bearing is intermittent Smaller, when the downtime is too long or large-sized impurities or foreign objects are brought in, the bearing will be intermittently sticky or blocked, which requires regular inspection, cleaning, and cranking inspection. The bearing needs to be removed and replaced when it runs to a certain period; ③Heat reflow The flow resistance is large and the cooling performance is poor, because the gravity return water secondary spray layout is similar to the traditional mechanical ventilation spray cooling tower, and the nozzle assembly is also used to concentrate the vertical upward spray, the spray flow is concentrated in the center of the tower, and the spray flow falls against the wind from The discharge from the bottom of the tower causes great ventilation resistance at the bottom of the tower, and it is difficult to achieve the best cooling performance; ④Limited by the performance of the atomization propulsion device, the spraying water density of a single tower is much lower than that of a traditional mechanical tower. In order to enhance the atomization effect, the nozzle diameter is small , easy to block, the actual cooling performance is poor, and it is far from being compared with the mechanical ventilation cooling tower; Good for industrial application.

Low pressure (0.08～0.12MPa) system return water residual pressure is sprayed out by the jet flow of the first-stage fixed atomizing nozzle assembly, respectively forming a good hot water atomizing flow, ensuring sufficient atomizing mass transfer area, and generating combined draft at the same time Performance The cooling air outside the tower is drawn into the tower through the air intake louvers, and mixed with the hot water atomized flow generated by the first-stage fixed jet spray nozzle group for mass transfer cooling and cooling.

Step 2: After the atomized and cooled mist stream of the first-stage fixed jet spray nozzle group is sprayed to the air outlet of the wire mesh at the top of the tower, a mass transfer liquid film is formed on the surface of the wire mesh to accelerate heat exchange and cooling with the cold air, and the mixed mist stream passes through The wall flow of the wire mesh fan cylinder is collected to the central water collection tank, and the cooling water in the central water collection tank passes through the lower connection potential energy return pipe to the bottom secondary fixed jet spray nozzle group by the differential pressure.

Step 3: The second-stage fixed jet spray nozzle group at the bottom converts the pressure by the potential energy of the potential difference to spray the first-stage cooling water in the central sump from the second-stage fixed-jet spray nozzle group at the bottom to form a mass transfer mist At the same time, the cold air is drawn in from the intake louvers at the bottom of the tower. At this time, the cold air is again mixed with the atomized flow of the secondary fixed jet spray nozzle group for cooling, mass transfer and cooling, so as to realize the second cooling, and the spray after the second cooling The flow is sprayed onto the circular table-shaped water-collecting wire grid set in the center of the bottom to form a liquid film and then transfer mass to cool down. At the same time, the secondary mist flow is collected by the circular-shaped water-collecting wire grid and flows into the bottom of the tower, eliminating the fall of the mist flow The anti-wind disadvantages caused.

Step 4, in the running state of the whole tower, the user can remotely adjust and control multiple sets of flow regulating devices set in the middle and bottom water distribution pipelines in the tower according to the system heat load status and actual cooling capacity demand, through the regulation system configured in the utility model, Real-time operating conditions such as water volume and water pressure can be remotely controlled to realize variable operation under variable operating conditions and achieve secondary savings in the comprehensive energy consumption of system equipment.

The adoption of this technical method produces the following beneficial effects: 1. The utility model not only inherits the energy-saving and environmental protection characteristics of the existing non-electric fan and no filler jet spray cooling tower, but also adopts the multi-stage combined fully fixed jet spray core atomization of the whole system The significance of the innovative and optimized design of the nozzle assembly is that it truly eliminates the performance limitations of the traditional hydraulic-driven fan-type swirling atomization propulsion device (that is, the device's water pressure is too low, the speed is too low, the atomization is not good, and the air volume is small; When the water pressure is too high, the speed is too high, the water volume is too large, the bearing wear is accelerated, and the service life is reduced), the applicability range of the operating conditions is greatly improved, and when the water pressure and water volume fluctuate, the fully fixed nozzle assembly automatically adjusts and matches, which fully meets and guarantees this requirement. The applicability of the utility model device to the working conditions of the actual operating system can achieve stable and reliable self-regulation, which is not available in traditional and existing jet spray cooling towers.

Generally speaking, when using the energy-saving and environment-friendly jet spray without fan and filler to transform the traditional large-scale mechanical ventilation filled cooling tower, a combination of multiple standard small-unit spray towers is used, that is, when transforming a traditional large-scale mechanical ventilation filled tower, It is necessary to re-arrange multiple sets of hydraulic-driven fan-type swirl atomization propulsion devices inside. Due to the limitations of the traditional hydraulic-driven fan-type swirl atomization propulsion devices, they cannot be self-balanced and adjusted. When multiple sets are arranged, it is impossible to ensure that each The running water volume and water pressure of the sets are evenly the same, so in the actual operation, there will be situations in which multiple sets of swirl atomization propulsion devices have different speeds, water atomization performances, and ventilation performances, which will cause different cooling performances of each unit, and eventually lead to the overall The comprehensive cooling performance of the tower is greatly reduced.
