technical field

The utility model relates to a high-efficiency atomization evaporation energy-saving cooling tower.

Background technique

The energy issue is one of the major social issues facing all countries in the world today, and energy is the material basis of modern society and life. With the rapid growth of the world's population and economy, energy consumption has also increased sharply, especially during the country's "Eleventh Five-Year Plan" period, the need for sustainable economic development has been put forward, and strict requirements have been placed on energy consumption in industrial production. How to effectively The optimal use of existing resources has become a new issue. Whether the operation of the cooling water system in some energy-consuming industries (phosphorus chemical industry, metallurgy, power generation, pharmaceuticals, air-conditioning and refrigeration, etc.) is economical directly affects the level of energy consumption. At present, the cooling towers on the market are mainly filled cooling towers with traditional technology. The cooling principle of this type of cooling tower is to prolong the contact time of water and air flowing down from top to bottom, and to increase the contact area between water and air through fillers, so as to achieve for cooling purposes. Long-term use of the filler is prone to fouling, and the water slides faster, resulting in a gradual decrease in cooling effect and unstable cooling effect. In order to ensure a better cooling effect, the user must invest a lot of money to regularly clean the scale or replace the packing regularly, which will increase the maintenance cost. The non-fill cooling tower can effectively solve the problems faced by the packed tower, but the cooling effect of the traditional non-filled cooling tower can only be comparable to that of the newly built packed tower due to the poor atomization effect of the nozzle. The invention discloses a high-efficiency atomization evaporation type energy-saving cooling tower. The cooling tower has uniform water distribution, better spray nozzle atomization effect and better cooling effect.

Contents of the invention

The purpose of this utility model is to disclose a high-efficiency atomization evaporation energy-saving cooling tower. The cooling tower adopts a high-efficiency atomization nozzle to spray water upwards in the middle and lower part of the cooling tower. The mist-like interval formed by the cooling water in the tower is effective. It solves the problems of low cooling efficiency, uneven water distribution, and serious drifting rain in the packed tower, and reduces the weight of the equipment, greatly reducing the workload of maintenance and cleaning. The tower has lower energy consumption and better cooling effect.

The principle of the cooling tower is to atomize water upwards into the cooling tower through the high-efficiency atomizing nozzle, and to achieve the purpose of cooling water by increasing the contact area between water and air and prolonging the contact time. With air contact, the evaporation speed is fast, the structure of the whole tower is simple, and the structural load is small.

The purpose of this utility model is achieved as follows: a high-efficiency atomization evaporation energy-saving cooling tower, which includes a tower body (1), a water distribution pipe (2), a support grid (3), an atomization nozzle (4), a collection Water dispenser (5), blower fan (6), air cylinder (7), support frame (8), liquid inlet pipe (9), air inlet louver (10) and water outlet tank (11) etc. The air enters the cooling tower from the air intake louvers under the action of the fan (6), the air flows upwards from the bottom, and finally is discharged through the air duct (7), and the hot water enters the water distribution pipe through the water inlet pipe, and goes upward with a pressure of 0.02MPa-0.05MPa The hot water is atomized and sprayed, and the hot water forms three heat exchange cooling processes in the tower, namely, the three processes of downstream, suspension and countercurrent. High-efficiency atomization increases the heat exchange area, and the hot water increases the contact time with the air through the three processes of forward flow, suspension and countercurrent flow, so the cooling effect of the cooling tower is better.

In this high-efficiency atomization evaporative energy-saving cooling tower, the atomization spray head is a low-pressure high-efficiency atomization anti-blocking spray head, which is composed of two "S" structures inside, and the atomization angle reaches 120 ^° .

In this high-efficiency atomizing and evaporative energy-saving cooling tower, the water eliminator is a grid grid demister.

In the high-efficiency atomizing and evaporative energy-saving cooling tower, the water eliminators of the cooling tower are arranged in one or more layers.

In this high-efficiency atomization evaporative energy-saving cooling tower, the tower body is empty between the atomization nozzle and the bottom of the water eliminator of the cooling tower.

In the high-efficiency atomization evaporation energy-saving cooling tower of the utility model, hot water and air form three heat exchange cooling processes in the tower, that is, three processes of forward flow, suspension and countercurrent flow. At the same time, the hot water encounters the rising air during its descent. The three processes of downstream, suspension and countercurrent prolong the heat exchange time, greatly improving the cooling efficiency and cooling capacity. There is no need to install packing in the tower, and the cooling efficiency is high and the energy consumption is low, which can effectively solve the disadvantages of the packing tower such as low cooling efficiency, uneven water distribution, and severe rain. Compared with the packed tower, the structure of the tower is simple, which can greatly reduce the workload of maintenance.

In the tower, it is in contact with cold air, and the contact process is divided into three processes: forward flow, suspension and countercurrent, so as to realize heat exchange and achieve the purpose of cooling circulating water.
