Counter Flow Closed Type Cooling Tower

 

As the main auxiliary equipment in the heat treatment industry, KBL series counter flow closed type cooling tower is used in heat treatment quenching media, controlled atmosphere multi-purpose furnaces, induction heating furnaces, vacuum furnaces, etc.; central air conditioning, forging, casting, chemical industry, food, injection molding, printing, generator sets, power plants, glass melting furnaces, and other fields.

 

 

 

Working fluid (soft water or other liquid) circulates in the coil of the counter flow closed type cooling tower, the heat of the fluid is absorbed by the wall of the coil, and the spray water is sprayed on the surface of the coil to produce heat exchange. At the same time, the cold air enters the tower from the air inlet grille at the bottom of the unit and circulates from bottom to top, evenly passing through the surface of the coil. A small part of the water evaporates and absorbs the heat, and the hot and humid air is discharged from the machine through the top fan, and the rest of the water falls into the bottom water tray for the next cycle. The fluid closed loop in the coil consumes very little, and the escape rate of the spray water is only 0.1%-0.2%.

1. Requirements for The Using Environment

* Avoid acidic exhaust gas, explosive dust, severe soot, and excessive water vapor;

* Placed next to a building, it should be kept enough distance from the air inlet (0.5-3M, depending on the model);

* Placed in the pit fence wall, it should be alert of heat discharge fault caused by hot and humid air reflow; an air induced device may be considered under special circumstances.

 

2. User Piping Problems

* Piping, pumps and valves should be installed below the running water level of the cooling tower to prevent overflow and air intake;

* When considering the equipment placement, there should be enough water pump head and the pressure loss to the head and pressure loss to the cooling coil pipe should be taken into account;

* The design pressure of interface flange for fluid cooling is 1MPa, and hangers or supports should be considered for all pipelines.

 

3. Maintenance Requirements of Spraying System

* As the closed cooling tower runs, minerals and other impurities in the water will precipitate and accumulate in the tank, so we must periodically check the water quality and blow down and clean on a regular basis, this can well control the water quality and prevent scaling.

* Requirements of spraying water quality: refer to GB50050-95 Code for design of industrial recirculating cooling water treatment; where there is water with specially poor quality, the purification (softening) shall be considered.

 

4. Supplement of Recirculating Water

* The recirculating water in the closed system should meet the requirements of production process for water quality, and softened water or purified water can be used.

* The closed system is equipped with a liquid level control system; if the system gives out a warning message, the level of recirculating water is low, and we need to add recirculating water.

 

5. Maintenance and Cleanup of Spraying Tank

* Note: the spraying water should be replaced periodically, and the spraying tank should be cleaned regularly.

* There are differences in water hardness in regions. Namely, it is recommended that the spraying water is replaced and the tank is cleaned up once every 5-6 months in the southern regions. In the northern regions, it is recommended that the spraying water is replaced and the tank is cleaned up once every 2-3 months. The actual replacement time shall be as the case may be.

 

6. Anti-freezing Problem of Closed Cooling Tower

* The anti-freezing measures for closed type cooling tower are generally classified into two categories:

(1). According to the temperature differences in regions, add anti-freezing solution according to the ratio.

(2.) Where the temperature is low, when the equipment does not run for a short time or stops running, the spraying water should be discharged to prevent freezing.
