Description

A New Type Counterflow Cooling Tower

technical field

The utility model relates to the technical field of energy saving and environmental protection of cooling towers, in particular to a novel counterflow cooling tower.

Background technique

Cooling towers play an important role in industrial and civil engineering, and cooling towers are also an indispensable part of enterprise workshops and residential facilities. It is a large-scale mechanical device that eliminates the waste heat generated by large-scale refrigeration air conditioners or modern industries through the contact between air and water for heat-cold exchange, and then through the steam generated by the heat-cold exchange. While my country's economy is developing rapidly, my country's energy consumption is also increasing, which is very unfavorable to the sustainable development of the economy. Therefore, whoever can grasp energy conservation and environmental protection on the future economic road can go further. The mechanical counterflow cooling tower is a kind of closed cooling tower. Because the equipment adopts a closed internal circulation method, it can ensure the quality of the water from pollution, and at the same time improve the service life of the cooling tower itself. Due to the wide application of cooling towers and the complex structure, in order to maximize the functions of cooling towers, the technical requirements of cooling towers are essential, such as the saving of kinetic energy consumption in the tower and the reasonable organization of airflow in the tower , noise control, optimal design of cooling towers, management methods of circulating cooling water, etc.

Whether in industry or in civil use, cooling towers are widely used. With the continuous expansion of cooling towers, the research on heat transfer and energy saving of cooling towers has become more and more in-depth, and the treatment methods have become more and more diversified, and the degree of attention has also increased, especially the heat transfer of cooling towers. more and more people's attention. At present, although the existing cooling tower heat transfer control theory and technology can control the noise of the cooling tower well, it often causes the heat transfer performance of the cooling tower itself to decline, so that the equipment cannot operate normally. With the development of society and economy, the problem of energy shortage is becoming more and more serious. Circulating cooling water is widely used in industrial water and is a key area of energy consumption. The cooling tower is the key equipment for cooling water circulation, and it is also an important part of the energy consumption of circulating water. Under the background of requiring energy saving and emission reduction, the energy saving of the cooling tower itself is urgent. my country's cooling tower industry started later than developed countries, but it has developed rapidly, and the gap with foreign countries has gradually narrowed. The research and innovation of cooling towers has developed rapidly, which also provides a guarantee for the energy saving of cooling towers.

In the traditional mechanical draft counterflow cooling tower, the fans are all installed on the top of the tower. Due to the high tower body, it is necessary to climb to the top of the tower for maintenance, which brings more inconvenience to the maintenance workers. The fan of the existing blowing countercurrent cooling tower is generally installed on the side of the bottom, or when it is installed at the bottom, no air distribution structure is installed. Therefore, for the bottom blowing countercurrent cooling tower, the motor has not been protected by isolating circulating water . In the normal operation state of the cooling tower equipment, part of the water will fall into the fan motor at the bottom, causing a short circuit and even burning the motor.
