Working Principle Of Drying Tower
Drying tower is a common drying equipment, its working principle usually includes the following steps:
Raw material feed: Raw material enters the drying tower through the feed port. According to the specific process requirements, the raw material can be liquid, suspension or slurry and other forms.
Dry gas entry: There is an air intake in the drying tower, and dry gas enters from here. Dry gases can be air, vapor or other gases. Parameters such as the temperature and flow rate of the drying gas usually need to be adjusted according to the nature of the raw material and drying requirements.
Gas-solid mass transfer and heat mass transfer process: When the dry gas enters the drying tower, the mass transfer and heat mass transfer process is carried out between the raw materials. The water molecules in the dry gas are separated from the surface of the raw material by evaporation and diffusion and mixed with the dry gas. In this process, the moisture content of the raw material is gradually reduced, making the raw material gradually dry.
Dry gas discharge: After the mass transfer and thermal mass transfer process, the dry gas will contain absorbed water molecules, but also will take away part of the dry material in the raw material. The top of the drying tower is provided with an air outlet through which the gas containing water molecules and dry substances is discharged.
Collection of dried raw materials: The bottom of the drying tower is provided with an outlet, through which the dried raw materials are collected. The collected raw materials can be used directly for packaging, storage or further processing. In short, the working principle of the drying tower is through the mass transfer and heat mass transfer process between the dry gas and the raw material, the water in the raw material is removed, so that it is gradually dried.
An evaporative cooling tower, also commonly referred to as swamp coolers, is one of the primary types of cooling towers. Since it is relatively new on the market, not many people have known it yet. The evaporative cooling tower is by far the most environmentally friendly and cost-effective among the different types of cooling towers. It features a perfect combination of convenience, style, and functionality, making them popular not only in industrial structures but also in residential buildings.
Benefits of Evaporative Cooling Tower
It is very cost-effective
The process of an evaporative cooling system is quite simple. It does not rely on compressing and cooling refrigerants as a typical air conditioning system does. Instead, it uses the natural process of evaporation. Approximately, the cost of operating an evaporative cooling system is merely a quarter of that of a refrigerated air conditioning system.
It requires less maintenance
The evaporative cooling tower requires minimal maintenance. Primarily, maintenance only includes cleaning the cooling pad. The tower only has to be washed once every one or two years.
As for repairs and replacements, the only parts that require repair whenever they are worn out are the water pump and the fan. Both of these parts can be purchased in minimal amounts. And they are also very easy to install. You don’t even have to pay for expensive HVAC contractor services for cooling tower parts repair or replacement and system maintenance.
It is more energy-efficient than other cooling systems
The evaporative cooling tower does not consume as much electricity as other air conditioning systems do since it has a comparatively current draw, making them more energy-efficient and cheaper to run. It does not also use any fan motor which typically consumes much energy.
It is easy to operate
The evaporative cooling towers are designed to provide ease of use. It has simple, straightforward controls with no complicated settings, making it easy to use. It also doesn’t use any compressor which often causes power spikes when you turn it on.
It is more environmentally friendly
The evaporative cooling tower does not require any special, expensive and toxic refrigerants like ammonia. Instead, it uses clean water for its fluid. This makes it safer for you and the environment. It does not only clean the air by providing enough humidity, but it also helps eliminate the contaminants in the air which deplete the ozone layer.
It emits less noise
The evaporative cooling tower offers quiet operation. It only operates at merely 50 dBA or below.
It comes with amazing convenient features
Just like any other swamp cooling towers, the evaporative cooling tower also comes with amazing convenient features such as air ionizer, 3 speeds, oscillation, and a sleep timer.
Easier and cheaper installation
Evaporative cooling tower installation is relatively easier and less costly as opposed to that of the central refrigerated air conditioning. It does not include complicated processes like installing drains or hoses. You just have to plug it in, add the required amount of water to the reservoir, and you are good to go. Installation cost is also generally just half the price or less than that of the refrigerated air conditioning.
It is highly effective
The evaporative cooling towers are highly effective in cooling the water and keeping the building or industrial machinery free from exceedingly hot water.
For residential buildings, it also offers enough humidification especially in dry climates, thus avoiding dryness while providing residents with a healthier, safer, and more comfortable indoor environment.
How Evaporative Cooling Tower Works
Evaporative cooling towers are able to best realise the water/air heat exchange process: evaporation is forced through the use of simple, effective components which normally require minimum maintenance.
To better understand how heat dissipation occurs, two concepts need to be introduced.
Sensible heat. This is the amount of heat energy that is added to, or subtracted from, a physical element (such as louvers) to change its temperature.
Latent heat. This is basically founded on the change of state that a substance can undergo as a result of heat addition or loss. In the case of water, it can change from a liquid phase to a solid phase (ice) if heat is removed when it reaches freezing point. It can also change from a liquid phase to a gaseous phase (vapour) if heat is added when it reaches boiling point. Latent heat is therefore defined as heat that is introduced or removed to change the state of the water. Specifically, in evaporative cooling systems, it is defined as latent heat of evaporation.
A well-designed evaporative tower is able to provide the water with as much air contact surface area as possible, in order to optimise the latent heat exchange.
To make this heat exchange possible, the evaporative tower must therefore be able to offer a very high air/water contact surface. This is achieved by means of a heat exchange surface, specifically designed for the purpose, and a fan able to move a defined volume of air according to precisely defined parameters. We will now look at the importance of these internal components in detail.
Components of Evaporative Cooling Tower
1.Basin
This forms the base of the tower, collecting the cooled water and providing a reservoir for the recirculating water system. Its volume is carefully calculated to maintain adequate water inventory, ensuring consistent performance and preventing pump cavitation. Thermal stratification can occur within the basin, with warmer water settling near the bottom and cooler water rising to the surface.
2.Fill media
This is the heart of the tower, consisting of specialized packing materials that provide a large surface area for the hot water to spread and facilitate heat transfer to the air. The primary function of fill media is to maximise the contact surface area between water and air. By employing intricate designs and varied geometries, fill media offer a vast canvas for heat dissipation. Beyond mere surface area, fill media actively facilitates efficient water distribution and interaction with the airflow. Certain designs fragment water into fine droplets, maximising air exposure. Others encourage thin water films to cascade down, mimicking a refreshing shower for the air.
3.Water distribution system
This network of pipes and nozzles evenly distributes the hot water over the fill media, ensuring optimal contact with the air for efficient cooling. The primary objective of the water distribution system is to deliver a uniform film of water across the entire surface area of the fill media. This necessitates careful hydraulic calculations to overcome pressure drops, ensure consistent flow rates across different sections, and minimize dead zones where water stagnates and contributes to inefficient heat transfer.
4.Air inlet louvers
These louvers regulate the airflow into the tower, allowing for proper ventilation and preventing water droplets from escaping. The primary function of air inlet louvers is to channel and direct the airflow into the tower. By employing angled blades or vanes, louvers create a controlled airstream that efficiently sweeps across the fill media, maximizing air-water contact and heat exchange. Proper louver design minimizes dead zones within the tower, ensuring all fill media areas experience optimal airflow and contribute to the cooling process.
5.Fan system
This system generates airflow through the tower, drawing in fresh air and expelling the heated air. Fans can be axial or centrifugal, each with its own advantages. Axial fans, resembling airplane propellers, generate high airflow volumes at lower pressures, ideal for open-circuit towers. Centrifugal fans, reminiscent of car engine fans, create high pressures with focused airflow, making them better suited for closed-circuit systems.
6.Drift eliminators
These are mesh-like structures that capture small water droplets entrained in the air, minimizing water loss and drift. Drift eliminators achieve their objective through various mechanisms. Common designs employ mesh screens, baffles, or inclined surfaces to intercept water droplets carried by the airflow. Droplets collide with the eliminator elements, lose momentum, and fall back into the water basin for recirculation.
7.Casing
This encloses the entire structure, protecting the internal components from the environment and ensuring structural integrity. The casing provides the primary structural support for the entire cooling tower, housing the heavy internal components like fill media, basins, and water distribution systems. It must withstand significant loads from water weight, wind forces, and seismic activity.The casing provides the primary structural support for the entire cooling tower, housing the heavy internal components like fill media, basins, and water distribution systems. It must withstand significant loads from water weight, wind forces, and seismic activity. The casing contributes to reducing water loss through drift. Its tight construction and strategic openings help capture entrained water droplets and direct them back into the basin for recirculation.
8.Makeup water system
This system replenishes the water lost through evaporation, purge (blowdown) and drift, maintaining the water level and ensuring efficient operation. Makeup water can be sourced from various options, including municipal supply, wells, surface water sources like rivers or lakes, or treated wastewater. The choice depends on availability, water quality, and cost considerations.
9.Control system
This system regulates the operation of various components, including the water distribution system, fan speed, and makeup water supply, optimizing cooling performance and energy efficiency. Typically, a cooling tower is run as a on/off system, directly controlled by the primary process’ SCADA according to predetermined setpoints required to be maintained for the particular process.
10.Access doors and platforms
These provide safe access through the cooling tower casing into the internal areas to maintain and inspect the tower’s enclosed components.
