Embodiment 1

[0032] see Figure 1-8, the present invention provides a technical solution: a multi-stage circulating jet spraying device for a filler-free cooling tower, comprising a cooling tank 1, a recovery cylinder 3 is fixedly connected to the top of the cooling tank 1, and a water pool is fixedly connected to the bottom of the cooling tank 1 2. The bottom of the inner wall of the cooling tank 1 is fixedly connected with a lower partition 13, and the lower partition 13 is provided with a ventilation groove 1301 near the outer edge, and the inner wall of the ventilation groove 1301 is fixedly connected with several guide grids 1302. The plate 1302 is inclined, and the ventilation groove 1301 can supply hot air and water vapor to discharge, and the inclined deflector grid 1302 can turn the gas flowing through, so that the water vapor flows longer, so that the water vapor has sufficient Time condenses and liquefies to further reduce the loss of water vapor. The top of the lower partition ...

Embodiment 2

[0035] Such as Figure 1-8 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: the secondary cooling device 9 is a spiral conduit, and the outer wall of the secondary cooling device 9 is evenly distributed with several spray heads 901 .

[0036] In this embodiment, the hot air mixed with water vapor passing through the installed cooling tank 1 will rise along the inner wall of the cooling tank 1, and when it reaches the inside of the recovery cylinder 3, it will pass through the shower head 901 outside the secondary cooling device 9. Spray cold water to cool down again, and the spiral secondary cooling device 9 can cool down in multiple layers, so that the cooling effect is better, the heat exchange is more sufficient, and most of the water vapor can be condensed into liquid droplets, reducing the loss of water vapor.

Embodiment 3

[0038] Such as Figure 1-8 As shown, on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: the end of each steam recovery device 14 away from the recovery cylinder 3 is inclined upward, and the bottom of each steam recovery device 14 is fixedly connected with at least A coagulation block 1401, the coagulation block 1401 is in the shape of a water drop with a small top and a big bottom.

[0039] In this embodiment, through the installed steam recovery device 14, the coagulation block 1401 at the bottom of the steam recovery device 14 adopts a streamlined water drop state, and the water vapor will move along the arc-shaped surface of the condensation block 1401, and finally hit the steam recovery device 14 Above, the water vapor is condensed and liquefied to release heat, the hot gas is blown out along the top of the recovery cylinder 3, and the liquefied water flows into the cooling tank 1 along the slope of the steam recovery devic...

Abstract

The invention discloses a multi-stage circulating jet spraying device of a packing-free cooling tower. The multi-stage circulating jet spraying device comprises a cooling tank, wherein the top of the cooling tank is fixedly connected with a recycling cylinder; the bottom of the cooling tank is fixedly connected with a water tank; the bottom of the inner wall of the cooling tank is fixedly connected with a lower partition plate; the top of the lower partition plate is fixedly connected with a lower hot water spraying head; an upper cooling device is arranged above the lower hot water spraying head; the top of the upper cooling device is fixedly connected with an upper partition plate; the outer wall of the upper partition plate is fixedly connected with the inner wall of the cooling tank; and an air cylinder is arranged in the recycling cylinder. According to the multi-stage circulating jet spraying device of the packing-free cooling tower, a multi-stage cooling mode is adopted, so that the heat exchanging efficiency is greatly improved; a multi-layer water vapor recycling device can reduce the water vapor loss; the waste is avoided; the water can be recycled; and the effects of high heat dissipation efficiency and small water vapor loss are achieved.

Description

technical field [0001] The invention belongs to the technical field of cooling towers, and in particular relates to a multi-stage circulating jet spraying device for a filler-free cooling tower. Background technique [0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it to the atmosphere to reduce the water temperature; its cooling is to use water and air to exchange heat and cold to generate steam, and the steam evaporates to take away heat to achieve evaporation The principle of heat dissipation, convective heat transfer and radiation heat transfer is used to dissipate the waste heat generated in industry or in refrigeration and air conditioning to reduce the water temperature of the evaporative cooling device to ensure the normal operation of the system. [0003] When the traditional non-fill cooling tower is in use: because it only uses water to exchange heat with the flowing air to remove heat, the eff...
