The ejection cooling towers successfully replace the fan and chimney-type cooling towers of a certain capacity, and in terms of the heat dissipation ratio, the reduction in the periodic and capital costs of maintenance, the ease of operation, the lack of maintenance, innovative solutions and economic indicators are much superior to other types of similar devices.
The principle of operation of the ejection cooling tower is based on the use of the ejection effect achieved with the help of special ejection nozzles in conjunction with guides for water and air flow.
The effect of ejection is as follows: a high-pressure working substance moving at high speed carries with it a working substance with a lower pressure. An entrained stream is called ejected. The main feature of the physical ejection process is that the mixing of streams occurs at high ejection (active) flow rates, in the case of a cooling tower - the flow of circulating water.
Features of the ejection cooling tower:
- ability to operate in discrete mode at any time of the year;
- has no restrictions on temperature and differences ( t ≤ + 90°C);
- high performance characteristics;
- high stable cooling tower efficiency;
- low energy consumption cooling towers (below 30%);
- there is no fan and sprinkler;
- there is no need for adding of water to reduce water temperature.
- Cleaning the nozzles without stopping the operation of the cooling tower;
- Lack of the basin (the underground tank) reduces the construction time and cost estimates;
- Significant reduction in maintenance costs due to the lack of a fan;
- Reduction of energy consumption and costs for maintenance staff due to system automation;
- Reduction of pipeline lengths by placing cooling towers close to production buildings;
- Adding of water to reduce the temperature of the water is not being used;
- Capital costs are 1.5-2 times lower (compared to typical fan cooling towers);
- Operational costs by 40% to 50% lower;
- Payback of the cooling tower by reducing the cost of water consumption and sanitation in the first to third months of operation.
