Description

Air cooling tube bank mist cooling system

Technical Field

The utility model relates to the technical field of air cooling equipment, in particular to an air cooling tube bundle spray cooling system.

Background

The air cooler is a closed indirect contact cooling device which is widely applied to the chemical industry, the axial flow fan sends normal-temperature air below the air cooler into a tube bundle of the air cooler to exchange heat with the tube bundle, the process medium in the tube bundle is cooled, the heat exchange effect of the air cooler depends on the ambient air temperature to a great extent, when the ambient air temperature is higher in summer, the heat exchange effect of the air cooler is poor, the full-load operation of the air cooler still cannot meet the production requirement for enabling the process medium to reach the specified temperature, the device can be maintained to operate only by reducing the load, and the yield and the operation efficiency of the device are reduced;

because the direct air cooling system directly utilizes dry air for cooling, the heat exchange efficiency of the direct air cooling unit depends on the temperature of the dry air ball entering the air cooler. By referring to the experimental results of the atomizing and humidifying tower in the chemical industry and the power generation industry, the temperature and the humidity of air at the inlet of the air cooler can be effectively reduced by adopting an atomizing and humidifying method, and the cooling capacity of the air cooler is obviously improved. The working principle is as follows: the water is atomized through the nozzle to form mist drops with certain particle size, the mist drops are fully mixed with air in the movement process, and the mist drops are quickly evaporated after absorbing heat on the surface of the air cooler tube bundle, and a large amount of heat can be absorbed during evaporation of the water due to the large vaporization latent heat of the water, so that the surface temperature of the air cooler tube bundle is reduced, and the purposes of improving the operation efficiency of the air cooler, reducing the operation pressure of a unit and increasing the efficiency of the unit are achieved.

The atomization humidification cooling device adopts desalted water as a water source, and a certain amount of desalted water is consumed and investment and operation cost are increased during working, but the cost is relatively small compared with the economic benefit brought by the improvement of the efficiency of a unit, and the economic benefit is considerable.

Currently, known atomizing humidification cooling devices are designed and installed below a lifting beam of a fan, and a nozzle opening sprays downwards, so that two problems are generated by the arrangement: if the nozzles are arranged at two sides of the fan bridge, the spraying direction is opposite spraying, but the nozzle is close to the outlet of the fan, so that tiny liquid drops formed by atomization are not evaporated sufficiently, and the cooling effect is affected; if the arrangement position of the nozzles is improved to the lower end of the lifting beam of the fan, one nozzle is adopted, although the evaporation process is prolonged, the atomization cooling effect is not improved because the water spraying direction is only reverse spraying, and the structure needs to be arranged under the lifting beam of the fan to influence the movement of the driving device of the fan after lifting, so that the atomization humidification cooling device needs to be disassembled before the maintenance process, and the device is time-consuming, labor-consuming and inconvenient.

Therefore, an air cooling tube bundle spray cooling system is provided to solve the existing defects.
