Large Cooling Square Tower

Toyo cooling tower design advanced, solid

The overall structural design of the cooling tower using the new CAD / CAM (production process software), the appearance of generous lines, high-grade, multi-table combination (can be a single run to achieve the purpose of energy saving) to save space, the overall structure of the solid and stable, good rigidity, resistance to 12 typhoons, 8 earthquake, snow load 200kg/m2. plus the tower is equipped with a patterned steel plate maintenance channel and the cooling tower conspicuously affixed with the on and off running Anti-electrocution and fall prevention signs, maintenance is very convenient and safe.

Steel bracket:

Tower body selection of national standard Q195, Q235 steel plate bending and forming production, surface anti-corrosion in accordance with the British BS ENISO 1461: 1999 standard hot-dip galvanised treatment will minimize the degree of oxidation, strong and durable.

Fibreglass shell:

Designed to use speed return transition energy-saving wind turbine, kinetic energy recovery rate of more than 30%, reduce the fan full pressure, reduce motor power, to achieve the purpose of energy saving and low consumption.

Water ride shell and chassis main materials are used to prevent acid, alkali and corrosion-resistant high-grade glass fibre reinforced plastic, superior tensile strength and conductive insulation, resistance to natural factors, ultraviolet rays and chemical erosion, as new as ever, flame retardant for 20 years without fading, long service life. Shell colour light grey for my factory's main colour, in full compliance with the owner's requirements.

Lowest noise, lowest cost

Fan:

Selection of high-strength aluminium alloy new large chord arc cooling tower special fan, large air volume, low noise, light weight. The surface layer of the 8-level high adhesion spray anti-corrosion treatment, anti-corrosion, anti-oxidation. Adjustable blade angle to meet different requirements, simple installation and maintenance. The number of fan blades is not 4, and the blades can be combined and disassembled conveniently;

Fan installation method inverted can reduce the cooling tower noise 3-5dB (A) and air outlet above the beam limit space less.

Motor:

Adopt the world famous brand ABB fully enclosed special cooling tower motor, protection level IP55, insulation level F class, by using more than ten years, outstanding performance, high efficiency, low noise, less energy consumption.

Good heat dissipation, less water drift

Filler:

Selection of high-quality polyvinyl chloride (PVC) materials, vacuum vacuum moulding, material strength and flexibility, anti-ultraviolet resistance, not easy to brittle, no porosity, no bubbles without obvious impurities and poorly dispersed auxiliary materials, the surface of the oil, no irritating odour, environmental protection, flame retardant, anti-aging long life. And the pattern adopts a unique "V" waveform twill design, which can effectively extend the contact time between water and cooling wind in the tower, wind resistance is small, good hydrophilicity, high cooling efficiency. The honeycomb water collection device at the end reduces the water loss to 0.01% of the circulating water volume. (Working water temperature -50 ℃ ~ 58.5 ℃, more than this value, please choose P.P material high temperature filler).

Uniform water distribution, easy maintenance, filler sheet has good thermal characteristics and resistance characteristics, can fully meet the cooling tower heat exchange and flow field design requirements. The filler frame and ladder are made of hot galvanised pipe.

Water distribution system:

Combined with years of manufacturing experience, according to the latest design theory of the international cooling tower industry, "Toyo" brand cooling tower adopts sprinkler basin and pool type water distribution, which has low water pressure into the tower, energy-saving, even sprinkler, and no moving parts. In addition, the middle of the tower is equipped with maintenance channels for more convenient maintenance.

Corrosion resistance, long life

Aluminium cable junction of external receiver parts:

Selection of special aluminium alloy material, with better stiffness and strength, light weight, easy to install the external receiver; cable tube interface sealing high, barge force uniformity; surface layer to do 8 high adhesion spray anti-corrosion treatment, corrosion and oxidation resistance.

The use of environmental temperature conditions are not restricted:

High temperature or sewage environment:

Circulating water temperature exceeds 58.5 ℃, PH value exceeds 6-8 containing strong acids and alkalis and water quality total solids exceed 5000mg / L, containing oil (tar) more than 10 mg / L or contain mechanical impurities with a diameter greater than 5mm, special design and production is required.

Low temperature environment:

Winter low-temperature icing environment uninterrupted use needs to be proposed, can be specially designed to add electric heaters and shower deflector ring, do not make the water flow to the louvre to prevent icing.

Cross-flow (RT) water ton both sides into the air square cooling tower advantages:

Extremely low noise

The noise of cross-flow cooling tower is mainly divided into two kinds:

The first one: wind noise

We take the treatment programme for

A after a long period of testing and user on-site testing and comparison, the Division developed aluminium alloy wide fan blade, large chord arc cooling tower fan noise than the same specifications of at least 3Db lower;;

B adopts the domestic famous brand ABB high efficiency and low noise type fully enclosed cooling tower special motor, coupled with imported belts (high temperature resistance, wear resistance) and factory transmission part of the dynamic, static balance treatment, will be able to control the noise to a minimum;

C: the transmission part is equipped with low-speed transmission to further minimise the noise;

The second type: water noise

We take the treatment programme as

A sprinkler basin with a cover plate to seal the noise of the pipeline into the water inside the sprinkler basin;

B sprinkler upper control: from the sprinkler basin to the filler of the water drop height of 180mm, surrounded by glass steel plate sealed in the tower;

C drenching water lower control: filler inserted into the water collection basin depth of about 50mm, no water fall sound issued;

D equipped with automatic float valve replenishment device, to prevent the cooling water in the catchment basin is pumped out of the noise;

E into the wind section around the installation of air intake louvres, can control the filler → water collection basin of the water fall sound in the tower;

Floating water is very little:

Toyo brand cooling tower whether it is counter-flow or cross-flow floating water loss is very little, we take the programme is.

A drive part is equipped with low-speed motor.

B Sprinkler system connection port is fully sealed;

C filler end on both sides of the self-bee snail-like water collection device;

D. Good sealing of the connection side of the glass fibre reinforced plastic shell, and if necessary, add sealant; E. Installation of a feeder around the inlet section.

E wind inlet section around the installation of air intake louvres, further water droplet loss control in the tower;

F water collection basin is equipped with an overflow device, when the flow rate or water replenishment is too large, it will not be allowed to full out of the outside;
