Air-side air and water mixed fine atomization enhanced heat exchange system for air cooler

Abstract

An air-side air and water mixed fine atomization enhanced heat exchange system for an air cooler comprises a water path assembly (1), an air path assembly (2) and a monitoring control system (3). Themonitoring control system (3) comprises an environment temperature sensor (32), a humidity sensor (31), a wind speed sensor (33), a wind direction sensor (34), a fin temperature sensor (35), a hard disk used for storing control data and a CPU used for processing data input by the sensors and sending control signals. Gas-liquid two-phase jet flow is adopted as a technical means, and the atomizationperformance is effectively improved on the premise of low energy consumption; and therefore, the system has the advantages of low energy consumption, low cost, high efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of gas-liquid two-phase atomization and heat transfer, in particular to an air-side gas-water mixed fine atomization enhanced heat exchange system for an air cooler. Background technique [0002] Circulating cooling system is widely used in metallurgy, petrochemical, electric power, chemical industry and other industries. With people's emphasis on water resources and the enhancement of environmental awareness, the cooling medium has gradually replaced water by air. The air cooler is the core equipment of the circulating cooling system. It uses ambient air as the cooling medium and sweeps the outside of the finned tube to cool or condense the high-temperature process fluid in the tube. It is called "air cooler" for short. Since the air cooler uses air as the cooling medium, seasonal changes in air temperature will affect the cooling performance of the air cooler. In recent years, the problem of high tempera...

Problems solved by technology

The disadvantages of this solution are: 1. To reduce the droplet size by high pressure, the overall pressure resistance level of the system needs to be set above 10MPa, and the energy consumption and cost will increase accordingly

2. The mist sprayed directly onto the fins will condense and combine with the dross in the air, forming hard-to-remove dirt on the surface of the fins for a long time, thereby polluting the fins and reducing their heat transfer performance

[0007] It can be seen that none of the existing technical solutions can automatically adjust the water spray volume according to the environmental conditions and equipment conditions, so it cannot automatically adjust the cooling intensity required by the actual power of the equipment; it cannot judge the actual situation of the environment, and it cannot adjust the water mist injection volume according to the temperature and humidity; in addition , the air cooler is often installed at a high place, once encountering weather with variable wind direction or wind speed, the atomized water will be sprayed with the wind to consume water resources in vain and fail to achieve the expected cooling effect
