Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a novel double-circuit cooling tower. Background Art

[0002] The closed cooling tower is a variation and development of the traditional cooling tower. It's essentially a combination of an evaporative cooling tower, a chiller, and a wet cooling tower. It's a horizontal evaporative cooling tower, with the process fluid flowing through the tubes and air flowing outside, without contact. Water from a reservoir at the bottom of the tower is pumped by a circulating pump and evenly sprayed over the tubes. This water doesn't come into contact with the process fluid, hot water or refrigerant, or the air outside the tubes, creating a closed cooling tower that enhances heat and mass transfer through the spray water.

[0003] The existing patent publication number is CN218937080U, which discloses a two-way loop cooling tower device, including a tower body with a water inlet at one end and an air outlet at the other end. The water inlet is connected to a plurality of nozzles via a water distribution pipe, and the bottom of the tower body is provided with an air inlet. Utilizing this device, the evaporative heat exchange efficiency of the cooling tower in the bypass flue heating + normal temperature evaporation process is increased by at least 100%, significantly reducing the equipment diameter and height, reducing the floor space required, and lowering the investment in the cooling tower. The utility model device has low requirements for particulate matter in the wastewater during operation and can operate normally under conditions of 5% solids content and 200μm particle size. It is suitable for cooling water systems and desulfurization wastewater normal temperature evaporation systems with high solids content, large particulate matter in the water, high viscosity, and easy scaling.

[0004] Existing closed cooling towers run for extended periods, and dirt and microorganisms accumulate on the water pan and coils. If not cleaned promptly, these can affect cooling efficiency and even clog the coils. To address this, we propose a new dual-circuit cooling tower to address these issues. Utility Model Content
