Abstract

The invention relates to a contact apparatus and m. used to cool recycled water in power plants and industrial plants. The invention makes it possible to increase the reliability of operation of the cooling tower (H) in winter. G is equipped with an additional sprinkler 6 and a water distributor 5, successively installed along the air movement to the main sprinkler 4. With negative tons of air, the main part of warm water enters the 1 G case for cooling. A part of this water enters the hermetic cavity 10 in the gap between the housing 1 G and the thermal insulation coating 9, and the other part of the water flows through the pipe 14 into the heat exchanger 13 located in the pan 8. Partially cooled water after the cavity 10 and heat exchanger 13 through the corresponding pipes 12 and 15 and the water distributor 5 is supplied to the sprinkler 6.

The invention relates to contact apparatus, and can be used for cooling the circulating water in power plants and industrial plants. with ti x.

The purpose of the invention. - improving the reliability of the cooling tower in winter.

The drawing shows a cooling tower, a longitudinal section.

The cooling tower contains the drift catcher 2 installed in the housing 1, the water distributor 3, the irrigator 4 and the additional water distributor 5 and the irrigator 6 placed in the upper part of the housing 1 fan 7, and in the lower part the pallet 8. The cooling tower is provided with a heat insulating coating 9 inside which Coaxially, the upper part of housing 1 is fitted with a shell that forms an airtight cavity 10 with nozzles for supplying 11 warm and discharging 12 cooled water, placed respectively in the upper and lower parts of the latter. In the pan 8, a heat exchanger 13 is placed with inlet 14 and a discharge pipe 15. Pipe 16 for supplying warm water is connected in parallel to the water dispenser

3 and pipes 11 and 14 for supplying warm water, respectively, the cavity 10 and the heat exchanger 13. The pipe 12 and 15 for discharging chilled water, respectively, the cavity 10 and the heat exchanger 13 are connected to an additional water distributor 5. The cooling tower also contains a device 17 for heating the drip pan 2, the outlet 18 chilled water from the pallet 8 and the air inlet windows 10, and the dimensions of the pallet 8 exceed the sizes located above the windows 19.

The cooling tower operates as follows.

At positive outside air temperatures, the water from the cold consumer (not shown) via pipeline 16 enters the water distributor 3, is distributed over the surface by steps 4 and 6 of the irrigator, where it contacts the air drawn in by the fan 7, cools and flows into the sump 8.

The cooled water from the tray 8 through the pipe 18 is fed to the consumer

cold weather At negative air temperatures, the device 16 is turned on to heat the drift catcher 2. The main part of warm water from the pipe 16 through the water distributor 3 enters the housing 1 for cooling, some of it enters through the nozzle 11 into the hermetic cavity in the gap between the housing 1 and the thermal insulation coating 9, which prevents freezing of the hull 1 of the cooling tower and the peripheral parts of the stages 4 and 6 of the irrigator. At the same time, part of the warm water also flows through the nozzle 14 into the heat exchanger 13 placed in the sump 8, which, in combination with the heat insulating coating 9, prevents the sump 8 from freezing. Partially cooled water after the cavity 10 and the heat exchanger 13 through the corresponding nozzles 12 and 15 and the additional water distributor 5 is fed to the lower stage of the irrigator 6, where it, together with the rest of the water flowing from the upper stage of the irrigator 4, cools down and drains to the sump 8. From the pallet 8, cooled water through the nozzle 18 delivers consumer.

Claims (1)

Invention Formula The cooling tower, comprising a housing with windows for supplying air, covers the insulating material, inside which a shell is formed coaxially to its upper part, which forms a cavity with the housing, evenly installed fan, drip tray, water distributor, sprinkler and a pallet in which the heat exchanger with the supply valve is installed and outlet nozzles, a pipeline for supplying warm water, connected in parallel to the water distributor, the inlet nozzle of the heat exchanger and the upper part of the cavity, characterized in Due to the reliability of the cooling tower operation in winter, it is equipped with an additional irrigator and a water distributor installed in series along the air flow to the irrigator, with an additional water distributor connected to the outlet of the heat sink: the bottom and the lower part of the cooling tower cavity.
