Evaporative air cooler

       1. Tube evaporative air cooler

       Tubular evaporative air cooler is a kind of cooling equipment that combines [plate heat exchanger + cooling tower + pool] into one, and it is a cooling equipment that integrates water cooling and air cooling, heat and mass transfer processes, and has both Both are long and energy efficient. It eliminates the secondary water re-cooling system, and has the advantages of compact structure, high heat transfer efficiency, low investment, low operating cost, easy installation and maintenance.

       2. Plate evaporative air cooler

       The plate type evaporative air cooler is similar to the tube type evaporative air cooler, except that the heat exchange element replaces the round tube with a more advanced plate tube. The so-called plate tube is made by welding two special corrugated plates, and its cross section is flat and rectangular. The plate bundle has a higher heat transfer coefficient than the tube bundle, and also has advantages in anti-freezing and anti-fouling.

Application field

        The evaporative air cooler solves the problems of poor cooling effect of the air cooler in summer, poor water quality of the cooling tower, and high operating cost of combined use equipment. It is widely used in industries such as metallurgy, power, oil refining, and chemical industry.

        1. Soft water closed circulation cooling system for blast furnace and hot blast furnace in ironworks;

        2. Continuous casting crystallizer, converter oxygen lance, heating furnace soft water circulating water cooling system in steel plant;

        3. Circulating water cooling system of steel rolling mill and coking plant;

        4. Circulating water cooling system for chemical, oil refining and other processes;

        5. Water circulation cooling system of power plant auxiliary machinery;

        6. Waste gas condensing system of power plant.

Features

       The evaporative air cooler adopts a modular design, which mainly includes: tube bundle, fan system, spray water distribution system, water collector, steel frame and spray pool, etc.

       Evaporative air cooler has good cooling effect, small pressure loss, long life, good pipeline dynamics, simple installation, small initial investment, low operating cost, stable system operation, low water quality requirements, water saving and energy saving, simple system maintenance, and cost Low, it can be arranged on the roof of the pump house, saving land resources and saving civil engineering investment costs. It is a new cooling method that replaces air coolers, cooling towers and other equipment.

In addition to all the advantages of the tube evaporative air cooler, the plate evaporative air cooler has the following characteristics:

        1. The specific concave-convex shape on the plate bundle can effectively disturb the water flow and air and improve the heat transfer coefficient;

        2. The rectangular channel of the plate bundle will not freeze and crack due to the freezing and expansion of the circulating water;

        3. The plate bundle can effectively avoid the scaling caused by the bottom of the heat exchange tube being dried;

        4. The plate bundle height is small, and it has a strong self-cleaning effect under the effect of spray water;

        5. The unique vertical channel of the plate bundle can be washed manually.
