Evaporative condenser is one of the important refrigeration products of Brapu evaporative condenser is widely used in the condensing and cooling of materials in petrochemical industry such as pressure reducing unit, catalytic cracking unit, hydrocracking unit, delayed coking unit, gas fractionation unit, alkylation unit, chemical industry methanol, synthetic ammonia, dimethyl ether, alkylation, benzene hydrogenation, coal tar hydrogenation, coal oil production, coal olefin production and coal ethylene glycol. The evaporative condenser combines the separate condensation process of the water-cooled condenser and the cooling tower with the water cooling process. It uses the cooling water to distribute the film on the surface of the heat exchanger, and the water film is in direct contact with the forced flowing air The cooling material transmits heat to the water film, which undergoes unsaturated evaporation and heat exchange and transfer with the air. It improves the traditional cooling mode in two aspects: one is to subtract the transfer process of cooling water from condenser to cooling tower, directly realize the reuse of water, and save the power consumption of water pump; the other is to change the way of single-phase cooling fluid cooling material with sensible heat temperature rise, mainly with the latent heat of water to take away heat. Its energy saving and water saving effect is not only obvious in theory, but also well proved in practical application.
 
 
Coil evaporative condenser
 

Coil evaporative condenser is to spray the cooling water on the surface of the tube to form a water film. After the water film and the medium in the tube have finished heat transfer, water directly contact with the fast flowing air outside the tube and heat exchange, complete the heat transfer process, and the air will take away heat and water vapor. Coil evaporative condenser is one of the most widely used evaporative condenser.
 
 
Plate evaporative condenser

The structure of plate type evaporative condenser: the countercurrent, downstream or cross current of water and air outside the plate, and the condensate drain area between the plates. The enhancement of heat transfer structure of the plate can improve the fluid flow condition, enhance the heat and mass transfer process between water and air, greatly enhance the heat capacity and heat transfer performance, and the enhancement of heat transfer depends on its own special structure to complete without any amount.
 
 
Vertical evaporative condenser

 

The structure of vertical evaporative condenser: the tube is a countercurrent or downstream flow of water and air, and the large space outside the tube is a condensate drain area. The characteristics of the condenser are as follows: the tube adopts stainless steel enhanced heat transfer tube, which not only has strong corrosion resistance, but also has good heat transfer performance and can accelerate the discharge of condensate film, especially for water vapor condensation. In the power industry, condenser is one of the important auxiliary machines of turbine generator set, and its performance directly affects the operation of the unit. And its main heat transfer components —— cooling tube is the most important part of condenser, so the selection and selection of cooling tube is the key to condenser design.
