Factors affecting the operation of the cooling tower

The cooling tower is a device in which water is exchanged for heat exchange with the flowing air, resulting in a change in water temperature,
    A common problem that hinders the normal operation of cooling towers is pollution. Inorganic solids such as dust, dirt, sand and silt are introduced from the atmosphere into the tower of water supply. These solids accumulate in the bottom of the basin, erode the circulation pump impeller, clog the nozzle, and in the heat transfer surface to form a large area covering, resulting in difficult to clean the situation.
    Another common contaminant in the cooling tower is organic solids such as leaves, grass chips, pollen, algae and bacteria. Compared with inorganic solids, organic solids tend to accumulate on the surface of the pot, nozzles and heat transfer surfaces. However, organic solids can pose a threat to human health.
    Managers have several ways to limit the impact of contaminants on cooling tower performance. Water treatment solutions can help reduce the amount of pollutants suspended in the water, limiting its ability to scale. This program can also help reduce the growth of organic pollutants.
    To limit the accumulation of organisms, we use two methods of water treatment - in the circulating water into the biological insecticide and ultraviolet antivirus. The bactericidal algae program must be designed to be in a specific environment where the tower is located and regular monitoring is effective. The UV system is installed indoors, and the circulating water is exposed to the intermediate level of ultraviolet light. Light is not dense enough, it can not destroy the majority of the body of DNA substances, or prevent its breeding.

Water inlet and socket outlet Cooling temperature control standard

Is a kind of circular cooling device for cooling towers, it absorbs the heat generated in the production by circulating water, entering the spray to fill the body of the tower, come into contact with atmospheric heat in Air, reduce the temperature of the water in circulation. By mixing hot and cold two fluids in contact with the tower with the temperature difference the uses are to cool the body after exposure to cooling water, the water evaporates into the air, obtaining a cooling effect.
Here to introduce cooling water tower temperature control input and standard output:
Tower water and temperature, cooling water is more effective cooling method measurement, is cool turns selection of important parameter, general situation Xia, civil cooling round tower design type workers standardized condition for water Temperature 37 ℃, water 32 ℃, in and tower water temperature for 5 ℃; Industrial with cooling tower design workers condition General 65 ℃ -45 ℃, 43 ℃ ℃ -33, 40 ℃ ℃ -32, several document, in and tower water temperature can up to 8 ℃ -20 ℃.
Cooling set duration to keep all aspects of the open, should not block can not appear, common plug of the pipe plug, packed due to excessive blockage scale, if there is a jam, Preferably in a first stage so that it can be cleaned to maintain the clear cooling tower water, to a cooling effect.

Considerations for winter maintenance of cooling towers

Winter Implementation Considerations
In operation in winter, the motor current is added, please note. In order to avoid the lower tank freeze, use antifreeze electric heater. Deck pumps, pipes using the heater and lowest water level in tank insulation jobs.
In order to avoid copper type tower cooling cooling (radiator) and distribution of frozen water, please note the following:
① in order to avoid freezing, water please participate the antifreeze water circulation, or participate in the piping to help electric antifreeze heating.
② After the addition of antifreeze, freezing temperatures drop, less likely to freeze. The higher the antifreeze concentration, the lower the thermal conductivity of freezing temperature will decrease, that is why in the selection to the attention of the cooling tower. If leakage, the water will dilute the antifreeze and freeze the rise in temperature, please note.
Circulation ③ as the pump rotates, electric heater anti-freeze heater, the water will not freeze. If an interruption of water circulation pump, circulator in others needs help, where we used the whole gel (with help, circulation pump heating antifreeze, piping).
④ directional valves settings 3 water system, water circulation via the bypass channel to control the volume of the opportunity, if you add a stream of bypass pipe, circulated decreased flow velocity of pipe in Copper, which can also occur when there is a load of frozen foods. Set the minimum flow rate for cooling towers.
⑤ to avoid pipes pump and apron apron, freeze, use electric antifreeze heating, adhere to the low temperature of the tank.

Notes on Wastewater Cooling Tower Maintenance

In other words, the wastewater cooling tower is the most prominent equipment in modern industry. Usually people will stop using the wastewater treatment tower for a period after using it for a long time.
To ensure that the wastewater cooling tower can function normally, it requires intensive care, even if you do not use it.

1. Try not to put the wastewater cooling tower in a dark and damp area or exposed to direct sunlight. Given the influence of the environment, its various parts will be corrosion and
Aging will shorten its useful life.
Suggest to place it in a ventilated place, it benefits from its maintenance.
2. Insert a clean cloth to cover the entire tower, to avoid dust on the surface, dust is difficult to clean after a long time if you do not use long.
3. You can paint mud oil on the surface of the tower, and add lubricating oil to the bolt and screw. Not only can it increase productivity, but also help expand service
Life of the tower.
In short, do not ignore the tower when you do not use it, it must be treated with care. Only pay attention to each link, do proper maintenance, make sure it works normally, improve production efficiency, to gain more economy Benefits and benefits to the company.

Influence of rain on the sewer cooling tower

It is the rainy season when summer comes, especially in southern China. Heavy rains and floods are common. The waste water cooling tower can be used both outdoors and indoors. If the wastewater cooling tower is used outdoors, the rain will enter the water from the spray cycle of the cooling tower.
In the process of rain, enter the recycled water from the cooling tower. The wall will absorb the soda ion and the carbon ion, the quality of the water will be acidified. If there is too much rain in the tower, it is necessary to change the sanding water in order to prevent the pipe from the cooling coil from being corrosive.
The entire pool of the sewer cooling tower is outside, but the tower is inside, so the rain will enter the pool and will work with spray water in the cooling cycle, Rain will affect the quality of the spray water, corrode the cooling coil and the body material tower, seriously affects the life of the cooling tower.
The cooling tower pool is inside, but there is a low water level, it is easy to enter the pool and fill it up. The rain is relatively small, we can, by chemical dosage, face the quality of the water. If there is plenty of rain, you must also change the spray water.
The influence of rain on the cooling tower is very great, it is easy to acidify the rain, so it influences the life of the cooling tower. So for the rain, we must be prepared and have a mode of treatment, avoid the serious influence of rain on the cooling tower lifetime.

Cooling tower water temperature is unusual

The analysis of failure causes:
The water inside the tower is not obstructed during the cycle.
The amount of water in the tower too much or too little.
The wind is not enough.
During the cycle, this phenomenon occurs, the hot gas makes the second
cycle.
And the cooling fins and heating pipes that have a significant influence on
temperature
How to resolve:
First check the water, check if the amount of water in the tower is
Meeting the normal standard, too much or too little water will cause
Increased water temperature. Then check the cycle system, whether it is hot
The gas is cycling. Finally, check the wind blower, the wind is not enough or not
Uniformly and nozzle jam will cause the temperature of the water to rise.
