Problems solved by technology

But owing to not being provided with any heating device in the sump in the main cooling system on the existing closed-type cooling tower, when this closed-type cooling tower is used in the cold winter of the north, the spray water in the sump is easy to freeze , thus affecting the use of the main cooling system

Embodiment Construction

[0011] Referring to a closed cooling tower shown in accompanying drawing 1, it includes an auxiliary machine part 100 and a main cooling system 200, and the auxiliary machine part 100 and the main cooling system 200 are respectively arranged on the main and auxiliary machine connecting base 16 of the cooling tower.

[0012] The auxiliary machine part 100 includes a soft water tank 24 and a soft water replenishment device 23 communicating with the soft water tank 24 .

[0013] The soft water tank 24 is used to store the circulating water of the cooling tower, and it has a soft water tank water inlet 11 on the upper part of the tank, a soft water tank water outlet 12 on the lower part of the tank, and an automatic exhaust valve of the soft water tank on the top of the tank 9. A water gauge 13 is also arranged on the soft water tank 24, and the water level gauge 13 is used to measure the water level in the soft water tank 24 to determine whether to replenish the soft water for cir...

Abstract

This invention relates to a closed cooling tower with spray-water automatic heating device including an assistant part and a main cooling part, in which the assistant part includes a soft water box, a supplement device and an electric control box set on the box, the main cooling system includes a shell, multiple fans set at the top in the shell, a water collector just under the fans, a spray branch system under the collector, a water tank set at the bottom of the shell and providing spray water to the spray branch system, a cooling coil pipe set under the branch system, an air inlet window set on the shell, in which the soft water box is connected with the coil pipe, a pump is set between the branch system and the water collecting tank with an automatic heating device, when the temperature in the tank is below 0deg.C, the device will be started up automatically and the pump will be closed, thus, water in the tank will not be frozen even if in winter and the main cooling system can work normally.

Description

technical field [0001] The invention relates to a closed cooling tower with an automatic electric heating device for spraying water, which is usually used in cooling systems of various equipment such as metallurgy and casting, and belongs to the technical field of refrigeration devices. Background technique [0002] Existing cooling towers include open cooling towers and closed cooling towers. Open cooling towers generally use open water cooling. The residual pressure of the circulating water pump is used to pump the circulating cooling water onto the packing of the cooling tower, and then the fan is used to cool the water through the packing, enter the water pan at the bottom of the tower, and then be pumped to the bottom of the tower by the water pump. Cooled by the cooling system. The biggest disadvantage of this cooling method is that the circulating water is easily polluted, causing scaling in the pipes and cooling system, which reduces the cooling efficiency, and it t...
