Operating principle
compared to open cooling towers. The cooled process fluid of the closed cooling tower flows in the closed pipeline, which avoids the process fluid pollution caused by the direct contact between the cooling water and the outside air, and makes the whole system more advantageous in operation and maintenance.
The unique composite flow technology of the TMC induced draft closed cooling tower combines the characteristics of the cross flow closed cooling tower and the open cooling tower, with high heat exchange efficiency and high operational reliability.
Internal circulatory system
The circulating water enters the heat exchanger after being heated by the heat source, and exchanges heat with the spray water and air flowing in the opposite direction in the corresponding tube through the heat exchanger tube, and sends the heat to the outside, and the cooled circulating water is sent to the environment by the system circulating water pump. heat source.
External water circulation system
The spray water is sent by the water pump from the lower water pan to the upper water distribution pipe. After the water is sprayed out, it first contacts the heat exchanger tube and the air entering from the upper part to exchange heat and heat up, and then falls to the packing area to exchange heat with the air entering laterally. , through the evaporation of part of the spray water to take away the heat, the cooled spray water falls into the lower water tray and circulates again.
(The internal circulating water exchanges heat through the heat exchanger tube, avoiding water pollution caused by direct contact between the external circulating water and air.)
excellent performance
(1) Efficient heat exchange
The high-efficiency heat exchanger adopts a serpentine structure coil, and the air and water flow in reverse directions inside and outside the coil to achieve the best heat exchange efficiency. After the whole heat exchanger is manufactured, it adopts the whole hot-dip galvanizing treatment to improve the anti-corrosion ability. Before the equipment leaves the factory, each pipe has passed three times of 2.5MPa strict air pressure test. Inclined design for easy fluid discharge. PVC filler can effectively increase the heat transfer area, prevent decay and microbial erosion.
(2) Reliable transmission system
It adopts a fully enclosed motor, which has a certain overload operation capacity and a long service life. The airfoil-shaped aluminum alloy fan with wide blades makes the unit run with low noise, low power consumption and high efficiency. Heavy-duty fan bearings have an L-10 life of 60,000 hours. Corrosion-resistant cast aluminum pulleys and high-quality high-strength belts are used inside to make the equipment run more reliably.
(3) Sprinkler system
Circulating spray water pump. It adopts 360° large straight nozzle, which is not easy to be blocked and ensures uniform water distribution.
(4) Corrosion-resistant structure
In the standard configuration, the steel plates used are made of galvanized steel plates. Special environments can also be equipped with stainless steel outer plates according to requirements. The louvers are made of corrosion-resistant PVC material, with large spacing to avoid clogging, minimize air resistance, and are easy to clean. The water tray is made of corrosion-resistant galvanized steel or 304 stainless steel, and the inclined design is easy to clean.
(5) Water retainer
The direction of air flow can be changed to reduce the loss rate of splashing water; it is made of corrosion-resistant polyvinyl chloride (PVC), and the detachable design is convenient for further maintenance of the coil part.
(6) Easy maintenance
The unit can be equipped with external maintenance ladders and escalators to ensure the safety of maintenance personnel, and the extended oil pipe is convenient for bearing lubrication. The hinged inspection door is easy to enter, and the unit has ample internal space; it can be equipped with an internal inspection platform to facilitate inspection and maintenance by maintenance personnel. The water collecting tray is designed to be inclined, which is easy to clean and can easily discharge the dirt from the water tray.
