Regarding the problem of cooler scaling
Thread Content
In order to solve the problem of scaling in the throat of the injector, the company added an atmospheric cooler in front of the injector. However, due to various reasons such as design, the water volume did not meet the design requirements, the water temperature was high, and the cooler was now scaled. Can anyone help me find a solution? illustrate: 1. The main reason for the scaling of the throat is that the evaporator has a large amount of steam and a high temperature. After the water passes through the ejector, the temperature rises to about 60 degrees. The main component of scaling is calcium carbonate. 2. The cooling water in the steam cooler is in direct contact with the steam, and the vacuum degree of the evaporator is -0. Around 06, the water flow in the sewer pipe is slow.
I read it several times and still didn’t understand what the original poster meant. I don’t know if this is my understanding or not?: 1. The evaporated steam from the evaporator is sucked out by the hydraulic ejector. The temperature of the steam-water mixture at the ejector outlet is high (about 60 degrees), and the pipe under the ejector is prone to scaling. ； 2. In order to reduce the temperature of the steam-water mixture at the ejector outlet, a cooler was added to the gas phase outlet of the evaporator to cool the evaporation steam. Now this cooler is also scaled. Regarding the fouling of the injector, is it possible to consider using desalted water or condensed water of evaporated steam as the driving medium for the injector to prevent fouling of the throat pipe? If you are unwilling to make this change and still want to lower the evaporation steam temperature, you can consider changing to indirect heat exchange between cooling water and evaporation steam to increase the heat exchange area of the cooler and increase the cooling water volume.

It’s a bit difficult to understand what the original poster means. What are the materials in the evaporator? Why do the cooling water of the condenser and the steam have to be in direct contact? Your poster said that it is better not to use the cooler, just change the water used in the injector to soft water, and circulate it with a pump, and replace the soft water regularly.
1. It is recommended to change the cooling water to soft water for cooling. 2. Use chemicals for cleaning and descaling. Generally, circulating water heat exchangers are often scaled. Please ask a professional cleaning unit to deal with it.
