Dry and wet combined closed cooling tower

Dry and wet combined closed cooling tower

Wet and dry joint closed cooling tower, referred to as wet and dry joint, or wet and dry mixed or wet and dry combination of closed cooling tower, is the use of dry and wet coil combination of ways, a collection of the advantages of the two kinds of heat transfer, dry coil to take advantage of the advantages of the local temperature is low, will be higher than the dry-bulb temperature of the medium to reduce to close to the dry-bulb temperature, only to consume the kinetic energy of the driving air flow, there is no consumption of any water. Wet coiler will reduce the medium to close to the wet bulb temperature, to make up for the dry coiler can not be to the wet bulb temperature of the shortcomings. Therefore, it can save a lot of water resources, favored by users.

Summarize

working process

► Production process equipment emits heat, which is transferred to the circulating medium, high temperature medium, through closed pipeline, into the dry and wet combined closed cooling tower.

► High-temperature media into the dry cooling coil, through the base tube heat transfer to the fins, and high-speed sweeping airflow, convective heat transfer, take away heat energy, reduce the temperature.

► cooling medium, and then into the wet coil, by the spray water evaporation condensation heat absorption, continue to cool down, the amplitude is greater than the dry coil, but the need to consume spray water.

► circulating medium cooled by dry and wet coils to meet the process requirements, closed back to the production equipment, once again transport heat, the cycle repeats.

Product Benefits

► dry coil: zero water consumption, no scale outside the pipe, high temperature on the direct drop, make full use of the project's local low air temperature characteristics, the use of air will be high temperature media, reduce the temperature of about 2 ~ 4 degrees, completely zero water consumption.

► Wet type: high efficiency, temperature difference, less investment, the circulating medium down to the required temperature of the production process, reducing the investment in dry coils.

Application scenario

► Northwest region: water-scarce arid areas, reduce water consumption, but also reduce the cost of branch;

► Power-rich regions: due to dry operation, the required air wind volume, fan motor power is also relatively large, electrical energy consumption, for wind power, hydropower and tidal, nuclear power-rich regions, more suitable.
