The difference between cross-flow cooling tower and counter-flow cooling tower

The difference between cross-flow cooling tower and counter-flow cooling tower

The so-called cross-flow cooling tower is a type of cooling tower that allows air to flow horizontally through the water spray filler, and the water dragon falls vertically from the top of the tower, and finally the water flow and the air flow are frontally converged to achieve a cooling effect. Counter-flow cooling towers and cross-flow cooling towers are our two most common cooling towers. There are many similarities between these two cooling towers. This article mainly makes a simple analysis of the difference between the two cooling towers. For many people who know cooling towers, the main difference between cross-flow cooling towers and counter-flow cooling towers lies in the cost, principle, maintenance, and cost.

1. In the high temperature range (HIGH RANGE), that is, the temperature difference between hot water and cold water exceeds 18 degrees, since the hot water needs to lower the temperature by more than 18 degrees in a short time, there must be sufficient time to contact the filler air, so the filler The work to be done is high. (Actually equivalent to two or three cooling)

　　Because the wind and water of the cross flow tower flow in a cross direction, the resistance is only related to the depth of the diameter and has nothing to do with the height, so theoretically it can be very high. The packing of the countercurrent tower cannot be made very high. The wind and water convection, generally above 1.5M, may cause air resistance. For example, the color coating and galvanizing cooling of the steel plant, the rubber plant, the hot water needs to be 55 Decrease the degree to 35 degrees or lower, you can use the cross flow tower.

　　 SKS steel water tower, filling height 5.5M, cooling temperature difference of 25 degrees; It is APP Jinguang Group's papermaking process, using 4000T/H single cell cross flow tower, filling height 15M;

2. In the case of sewage, the cross flow tower can use grid packing, and it can be easily cleaned at any time without stopping; although the counter flow tower can use grid packing, cleaning is problematic, and in actual engineering, sewage is often accompanied by high temperature, so Cross-flow towers can be two-pronged.

　　 The above is the difference between the cross flow cooling tower and the counter flow cooling tower introduced by the editor of okmarts.com today. I hope you can choose the most suitable one according to their differences and your actual situation when purchasing.
