Energy saving cross flow fiberglass cooling tower

Overview of energy-saving fiberglass cooling tower products

The design of energy-saving fiberglass cooling tower adopts the "square counter current cooling tower with inclined ladder wave opening packing sheet",Its heat The resistance characteristics are all related to it He filled in. The meaning of the cooling tower code is as follows:

Divide by water temperature:

① Low temperature drop, design water temperature drop 5℃ (before low-noise code)DIndicating ultra-low noiseCDRepresentation);

② Medium and high temperature drop, water temperature drop 10－25℃, before the codeGexpress.

Composition of cooling tower components:

① No water disk (code ends withLRepresentation);

② Shallow Water Plate (code ends withDPRepresentation);

③ Deepwater Plate (code ends with)GPExpressing),Effective water storage depth of deepwater tray400mmIf an increase in water depth is required, it must be mentioned when placing an order Get out.

In the codeFNRepresents a square counter current steel structure.

The numbers in the code represent the specifications of the cooling tower, that is, the amount of cooling water per unit under design conditions, in units ofm3/h(Facade and foundation drawings) Two towers are shown, which can be arranged in a single row with multiple units, or in a double row with multiple units.

Selection and use of fiberglass cooling tower ：

When choosing this type of cooling tower, it is necessary to know the amount of cooling waterQAnd the temperature of the inlet towert1The temperature of the water outlet towert2, air wet bulb temperature τ， According to this explanation The thermodynamic performance curve determines the specifications of the tower.

The material of the cooling tower can withstand one 50℃ low temperature, for the coldest month with an average temperature below one 10Take anti icing measures in areas with a temperature of ℃. cycle The turbidity of water is not greater than50mg/1In the short term, not exceeding50mg/1It should not contain oil stains and mechanical impurities. If necessary, measures should be taken to eliminate algae and improve water quality Stability measures.

The load carried by the foundation of the cooling tower can be found in the "Foundation Burial Plate and Load Table". The direction of the inlet and outlet pipes of the cooling tower is as follows 90° 、180° 、270° Rotate. The water distribution system is designed based on the nominal water volume, such as the difference between the actual water volume and the nominal water volume ±15%The above should be explained when placing an order. The inlet water temperature of the cooling tower shall not exceed 60℃, if exceeded 60The temperature should be specified when ordering.

The installation angle of the fan blades can be adjusted, but it must be ensured that the angle is consistent and the current of the motor does not exceed the rated current of the motor. The fan can be short Reverse at low speed to remove ice. When using the water tray of a cooling tower as a water pool, special attention must be paid. The cooling tower quotation does not include this part of the price.

During the storage and transportation of cooling tower components, heavy objects should not be placed on them, and they should not be exposed to direct sunlight. Attention should be paid to fire prevention, installation, transportation, and maintenance During the repair process, no open flames such as electricity or gas welding are allowed, and no firecrackers or fireworks are allowed to be burned nearby.

The operating weight of this fiberglass cooling tower is based on the thickness of the filling water film0.5mmWithout considering the weight of scaling and adhesion of other impurities, If the water quality is poor, it is recommended to increase the wet weight appropriately. The basic load has been calculated based on the weight of scaling.

Design parameters:

Air wet bulb temperature τ=28℃, inlet water temperaturet 1 =43℃, outlet water temperaturet 2 =33℃. atmospheric pressureP=1.0×10 5 pa.

Structural features: This series of cooling towers has good thermal performance, low power consumption, good stability of the entire tower, beautiful appearance, low noise, and short construction and installation period Due to its low cost advantages, it is widely used in a large number of circulation systems in enterprises such as petroleum, chemical, metallurgical, and power. Energy saving fiberglass cooling tower By using a variable torque and variable pole motor, it can save energy on electricity consumption throughout the year while ensuring thermal performance40%-52%At the leading level both domestically and internationally. The packing material used for the square counter current cooling tower is inclined trapezoidal wave packing, characterized in that the inclined trapezoidal wave forms packing blocks by bonding rope heads, ensuring stability Good, durable. The trapezoidal wave height23mmReducing ventilation resistance can increase the filling height1.0mincrease to1.5m,Improved thermal performance.

Tower structure under stress: For steel frame structures, the maximum amplitude during operation0.14mmThe steel parts have been strengthened with anti-corrosion measures, and two coats of epoxy asphalt paint have been applied after galvanizing.

Enclosure structure: It is made of polyester glass fiber reinforced plastic, light in weight, high in strength, corrosion resistant, beautiful and anti-aging.

Wind duct: For kinetic energy recovery type, with reasonable airflow organization, high efficiency, made of fiberglass material, lightweight, high-strength and corrosion-resistant.

Fan: The blade material is epoxy fiberglass, the blade is wing shaped, filled with foam plastic, and the fan has reasonable aerodynamic force, large air volume, and high efficiency Low noise and corrosion-resistant.

Reducer: Horizontal, low noise, high efficiency, reliable oil lubrication, easy maintenance, and also equipped with oil temperature and vibration alarm devices.

electric machinery: The motor is a specialized variable torque variable pole variable speed motor for cooling towers. There are two types: explosion-proof and non explosion-proof. 800 reach 1000 Dual speed configuration,1200 type The above is a three speed cooling tower with significant energy saving, known as an "energy-saving cooling tower". The motor speed can be manually or automatically controlled through the control cabinet. variable speed motor Compared with single speed motors that can save electricity during cold weather shutdown, dual speed motors can save electricity annually40%Three speed is50%Above, it operates flexibly. When the temperature When the humidity is high or the water temperature of the water equipment drops significantly, turn on the high speed. Conversely, turn on the medium or low speed. At night, if the temperature is low, turn on the medium or low speed. here The noise level can be reduced3-6db（A）Above. During winter icing, the fan can be turned on at low speed and reversed to clear the ice. Driving at a low speed in winter also reduces the floating water To the point of being ignored. The surrounding environment will not be polluted due to icing.

Packing: The filler sheet pressed a small wave on the large wave, High rigidity Large surface area, Strong ability to redistribute water Uniform formation of water film Long dwell time, Water droplets do not avoid the filler and fall directly. There are bi-directional convex and concave installation heads on the filling material, which are assembled and bonded firmly, do not collapse or deform, and have poor water quality It is also less prone to adhesion and blockage. The filler is modifiedPVCMaterial, temperature resistant-35℃-65℃, flame retardant. Performance should comply with energy requirementsNDGJ88-89Cold Technical regulations for plastic water spray filling in Queta.
