Embodiment 1

[0042] Such as Figure 1-Figure 3 As shown, the multi-stage jet spray gravity return water fan and filler-free cooling device provided by this embodiment is provided with a middle-stage fixed low-pressure swirl atomization nozzle assembly 6 and a bottom-stage gravity return low-pressure swirl atomization nozzle Component 8.

[0043] The intermediate stage fixed low-pressure swirling atomization nozzle assembly 6 is located in the middle of the tower, and the low-pressure jet sprays the temperature, and it has the effect of jet atomization and air extraction to ensure a high water density of the whole tower. The bottom stage gravity return water low pressure swirl atomization nozzle assembly 8 is at the bottom of the tower, the full-wire mesh convergent expansion type outlet tube 16 collects water to the sump 4, and the downpipe 7 is connected to the bottom stage gravity return water low pressure swirl atomization nozzle The component 8 is sprayed to cool down again to enhance th...

Embodiment 2

[0046] Such as Figure 4 As shown, the multi-stage jet spray gravity backwater fan and filler-free cooling device provided by this embodiment is connected to the lower side of the middle-stage fixed low-pressure swirl atomization nozzle assembly 6 through the water distribution pipe 13 to the middle-stage second-layer fixed low-pressure swirl Flow atomization nozzle assembly 17.

[0047] The second-layer fixed low-pressure swirl atomization nozzle assembly 17 and the middle-level fixed low-pressure swirl atomization nozzle assembly 6 distribute the required number of nozzles, calibers and angles, etc., which can effectively increase and adjust the total tower water intake, that is, the spray density. Solve the shortcomings and disadvantages of the traditional spray cooling tower that the single-layer nozzle arrangement is insufficient and the water distribution is too concentrated.

[0048] During the implementation of this embodiment, two or more middle-level fixed low-pressure sw...

Embodiment 3

[0051] Such as Figure 5 As shown, the multi-stage jet spray gravity return water fan and filler-free cooling device provided by this embodiment is connected to the bottom stage second layer gravity through a water distribution pipe 13 on the upper side of the bottom stage gravity return water low-pressure swirl atomization nozzle assembly 8 Return water low-pressure swirling atomization nozzle assembly 18. The bottom-level second-level gravity backwater low-pressure swirl atomization nozzle assembly 18, together with the bottom-level gravity backwater low-pressure swirl atomization nozzle assembly 8, distributes the required number of nozzles, caliber and angle, etc., which can effectively increase and adjust the entire tower The gravity return water volume of the sump 4 makes full use of the space at the bottom of the tower body, effectively increases the cooling range of the bottom of the tower, and increases the cooling performance.

Abstract

The invention belongs to the ventilation cooling technical field, and discloses a multi-stage jet spray gravity backwater draught fan-free filler-free type cooling device provided with a tower body framework; the inner side of the tower body framework is provided with a water collecting tank; an opening of the upper side of the water collecting tank is connected with a wind tube demister in a bolting manner; the outer side of the water collecting tank is connected with a lateral demister in a bolting manner; the center of the interior of the water collecting tank is provided with a central-stage hydrodynamic propulsion atomizer; the lower side of the central-stage hydrodynamic propulsion atomizer is connected with at least one middle-stage fixed low-pressure rotational flow atomizing nozzle assembly through a water distribution pipe, and the lower side of the middle-stage fixed low-pressure rotational flow atomizing nozzle assembly is connected with at least one bottom-stage gravity backwater low-pressure rotational flow atomizing nozzle assembly through a water distribution pipe. The technical bottlenecks of poor atomization mass transfer performance, poor flow field and low cooling temperature difference of traditional spray cooling towers are broken through, the cooling performance of the cooling device is better than that of a mechanical ventilation cooling tower, and the cooling device has good cooling performance, energy-saving performance and maintenance performance; at the same time, the investment cost is reduced under a requirement of a certain tower height.

Description

Technical field [0001] The invention belongs to the technical field of ventilation and cooling, and in particular relates to a multi-stage jet spray gravity return water fan and filler-free cooling device. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: [0003] At present, the commonly used circulating water cooling towers at home and abroad mainly include natural draft cooling towers, mechanical draft cooling towers and traditional spray cooling towers. [0004] Natural ventilation cooling towers are tall (ranging from tens of meters to hundreds of meters), engineering difficulties and investment are large, and temperature differences are small; mechanical ventilation cooling towers use electric fans to force air, and various types of corrugated packings are used as liquid and mass transfer components , The technology is mature, but the power consumption of the electric fan is high, the maintenance cost is high, the fi...
