There are many kinds of specifications and models of cooling towers. Choosing the right cooling tower can make its effect stronger, so that the heat and cold exchange between water and gas can be caused by the stronger fluidity of the water and gas when touching the steam, so that the steam evaporates to generate heat and achieve volatilization and heat discharge. Therefore, the choice of cooling tower is also an insight.
1, the tower structure material of the cooling tower should be strong, durable, corrosion resistant, and properly assembled with each other.
2, the use of centrifugal water pump should be matched with cooling tower facilities, to ensure the total flow, pump head and other processing technology requirements. The water distribution is uniform, the wall flow is less, the splashing equipment is fair, and it is not easy to block.
3, the form of cooling tower sprinkling filling material conforms to the water body, temperature request.
4. Centrifugal fan matching will ensure long-term abnormal operation, no vibration and abnormal noise, and the leaves have good moisture and corrosion resistance and sufficient compressive strength. The Angle of the centrifugal fan leaf equipment is adjustable, but it is necessary to ensure that the Angle of view is consistent, and the electric flow of the motor does not exceed the rated voltage of the motor.
5, low energy consumption, low project cost, small and medium-sized closed cooling tower also request light weight.
6, cooling tower equipment parts are matched with it, in addition to taking into account the natural ventilation request of the tower, tower and the building mutual harm, should also take into account the building fire safety, explosion-proof commercial insurance distance and cooling tower engineering construction and examination request. Should minimize the distribution of pyrogen, organic waste gas and smoke caused by the point and its chemical accumulation with the material heap adjacent.
7, The inlet direction of the cooling tower can be rotated according to 90°, 180° and 270°.
8, the material of the cooling tower can withstand -50℃ ultra-low temperature, but the average temperature of the cold moon is less than -10℃ to indicate that it is easy to use the anti-freezing method. Cooling tower project cost increased by about 3%.
9, the turbidity of the circulating water is not more than 50mg/ L, and it is not suitable for oil stains and reflective residue. When necessary, the method of algae killing and water body sturdiness should be adopted.
The basic principles should be paid attention to when selecting square tower cooling tower:
1. The temperature request of circulating water can be divided into high temperature tower, medium temperature tower and normal temperature tower.
2. For the request of noise, there are standard cooling tower, low noise cooling tower, ultra-low noise cooling tower.
3. For the current condition request of the equipment part, the cooling tower selection includes: diffuser tower and backflow tower.
4. The model selection of the cooling tower on the rule is that the circulating water quantity is slightly larger than the cooling water quantity of the refrigeration unit.
1, taking into account the sprinkling density in the calculation of cooling tower. Density is the amount of water that can be cooled per hour over a reasonable area of 10m2. This is indicated by the marker Q. Q = q /Fm3/m2 h (q - total flow of cooling tower, m3/h; F- Reasonable total area of sprinkling for cooling tower, m2).
2, after cooling temperature t2 with dry bulb temperature of gas temperature is deduced endangered levels Δ t Δ t = t2 - factor (℃) Δ t call it to cool high. The smaller the Δ t 'value, the better cooling effects. In fact Δ t 'is unlikely to be zero.
3, cooling tower water penetration of the difference between the temperature of t1, water temperature t2 Δ Δ t t, is called the cooling water temperature difference. In some cases, the greater the temperature difference, the better the adverse effects of cooling. For manufacturing, the bigger the Δ t is the total capacity of production line equipment are in need of cooling water will go down. T1 but if ooze water temperature is high, even if Δ t temperature difference is very big, the temperature of the cooling after landing not to accord with the request, so that a parameter values are needed, but that problem is insufficient.
