A prerequisite for stable and long-lasting operation of the heat exchanger is regular maintenance of the device, cleaning of plates, elastic gaskets, all parts and assemblies from contamination. To do this, use a means for washing heat exchangers. What it is and how it is applied - say the engineers of the company "ProTeplo" www. proteplo. org.
In most cases, plaque is:
It is formed by the circulation of liquid with impurities that regularly accumulate on the inner walls of the heat exchange equipment. Without flushing, the thickness of the sediment is constantly increasing, impedes the movement of the working medium, interferes with the normal operation of the apparatus and reduces its effectiveness.
Washing of the collapsible plate heat exchanger is possible chemically and mechanically. The first method does not require disassembly of equipment, is more popular. Mechanical cleaning options are used only with a high degree of contamination; they are distinguished by the need to dismantle the heat exchanger and large temporary labor costs.
The main rule when selecting a fluid for flushing heat exchangers: the chemical components in the solution should aggressively affect scale, but be neutral with respect to the plates, elastic seals and other parts of the device. This will allow to get rid of pollution and not damage the elements of the device.
Criteria for choosing a means for cleaning a plate heat exchange structure:
looks ready to work To minimize the risk of damage to internal parts of the unit It is recommended to analyze the sediment to determine its chemical composition. This will allow you to choose the most effective and safe means for cleaning the heat exchanger.
Manufacturers produce means for removing plaque heat exchanger in three versions:
The first two types require preliminary preparation and dilution with water in the proportion specified by the manufacturer. You can select the washing agent for heat exchangers and boilers here.
Modern detergents are distinguished by a variety of chemical composition for the ability to choose the best option for devices of different materials. The concentrate includes:
Additionally, antifoaming agents and components can be included in the product to avoid layering.
The cleaning solution formulation provides for the loosening of carbonate pollution and its transfer to a soluble state, as well as the creation of a protective film to prevent metal from corroding. Manufacturers have thought over the color change of the liquid during the washing process to control the process.
Main types of pollution and optimal detergent mixtures:
As an alternative, a mixture of sodium carbonate and caustic soda can be used to remove contaminants. It is less harmful to humans, but it does not fight against all types of layers, it is optimally suited for removing biological contaminants, fats and oils.
The gas boiler can be cleaned at home by yourself. The need for such an event arises when the following symptoms appear:
At home, the following drugs are suitable for washing the heat exchanger:
When using the solution, it is necessary to use protective equipment and observe safety precautions.
The main advantage of industrial concentrates is the availability of mixtures of corrosion inhibitors and the calculation by experts of safe proportions of chemical components. Using the correctly chosen washing mixture, the owner will be able not only to carry out effective washing, but also to protect the surface of the heat exchanger plates from the appearance of corrosion, and will prolong the life of the device.
