What are the types of cold mist fountains
Cold mist fountain is a landscape and environmental conditioning device that uses a high-pressure system to atomize water into micrometer sized particles and spray them into the air. Its core functions are to create visual mist effects, local cooling, and assist in air purification. This device is typically installed in open or semi open public spaces and operates as an independent or modular landscape unit. In environmental applications, cold mist fountains help to reduce local air temperature, increase humidity, and reduce suspended particulate matter concentration in the air through water mist adsorption.
Cold mist fountain working principle
The working cycle of the cold mist fountain mainly includes four stages: water supply, pressurization, atomization, and diffusion. Firstly, the raw water is filtered through a multi-stage filtration system to remove impurities before entering the high-pressure water pump; Subsequently, the water pump pressurizes the water to above 4.5 MPa and delivers it to a dedicated atomizing nozzle; Inside the nozzle, high-pressure water flows through a microporous structure or needle device and is broken into small water mist particles with a diameter of 1-15 microns; These mist particles diffuse into the air with the airflow, quickly evaporate and absorb heat, achieving a cooling and humidification effect. When the system detects that the pressure difference before and after the filter reaches the preset threshold, it automatically triggers the backwash program to remove suspended solids trapped on the surface of the filter element. The whole atomization process runs continuously, and the backwashing operation can be completed synchronously without affecting the spray function of the main system, so as to ensure the long-term stable operation of the equipment.
Cold mist fountain Core structure composition
The atomizing nozzle component is made of stainless steel SS304 or ceramic material, responsible for converting high-pressure water flow into micrometer sized droplets, ensuring uniform atomization and corrosion resistance.
The main body of the high-pressure water pump system is a stainless steel SS316L pump body, providing stable high-pressure power and ensuring continuous atomization capability.
The multi-stage filtration device is equipped with pre installed PP cotton and precision filter element (precision 5-50 μ m) to prevent nozzle blockage and extend equipment life.
Pressure and flow sensors monitor the operating parameters of the system in real-time and provide feedback to the control unit.
The PLC automatic control system adjusts the start stop, pressure, and backwash cycle based on preset logic, and supports remote monitoring.
The main structure of the equipment frame and pipeline shell is made of Q235 carbon steel sprayed or SS304 stainless steel, suitable for outdoor installation requirements.
Technical features and performance
According to relevant technical information and actual project data, this device usually exhibits the following characteristics in application
1. The concentration of particulate matter in the emission area can be reduced due to the adsorption effect of water mist, and the local PM10 concentration is usually controlled at a lower level;
2. The operating energy consumption is relatively low, with a unit processing energy consumption generally below 0.8 kWhm ³ (based on water supply);
3. The backwash water consumption is relatively low, with a single backwash water volume of about 0.5-2 m ³ h, depending on the filtration area;
4. The equipment has a small footprint and is suitable for landscape renovation projects with limited space;
5. The automation level is high, and the maintenance frequency is usually once a month for routine checks, which helps to ensure operational stability.
Cold Mist Fountain typical application scenarios
1. When applied in urban parks and squares, this equipment is mainly used to create dynamic foggy scenery and microclimate regulation, which helps to improve the comfort of public rest.
2. When applied in this field, the dust reduction equipment in industrial plant areas is mainly used to suppress dust in open-air yards or loading and unloading areas, which helps to reduce the concentration of dust in the surrounding air.
3. When applied in this field, this equipment is mainly used to enhance the natural atmosphere and immersive experience, which helps optimize the overall landscape hierarchy.
4. When this device is applied in this field, it is mainly used for outdoor cooling and atmosphere creation in summer, which helps improve the customer's stay environment.
The cold mist fountain has certain applicability in environmental protection related scenarios, and its technical characteristics are reflected in high atomization accuracy, low operating energy consumption, compact footprint, and controllable backwash water consumption. The actual performance of the equipment is affected by factors such as inlet water quality, environmental temperature and humidity, and operation and maintenance status. When selecting engineering models, it is necessary to combine specific working conditions and reasonably configure filtration accuracy, nozzle layout, and control systems to achieve good processing results.
