The most popular types of heat exchange units are installations with specialized plates. What is the current compact micro channel porous flow plate?
It is the collapsible plate heat exchanger that is most common, since it can disassemble the internal units, which makes maintenance more convenient.
In general, one might think that the design of plate heat exchangers has a simple device, but this category of equipment also has its own characteristics.
It is very important to choose the right material for specific operating conditions. In addition, the features of the plate devices include the presence of seals that are also select for certain environments and temperatures.
Detail of Compact micro channel porous flow plate
The number of compact micro channel porous flow plate always varies, that is, it is different. Their total number is comparing with the parametric characteristics of the equipment, schemes and principles of its operation and future conditions of its operation.
Each plate is locating inside the installation, specific gaskets is easy to fix next to it. Their need is since to create an isolation of flows that contain a coolant and other media.
THE ACTION OF THE SEALS
It is this category that does not allow mixing of media and creates a seal. Nowadays, only 2 classes of these elements are in widespread use: adhesive or clip-on.
Current installations in one package can contain from 1 to several sets of plates. Furthermore, compact micro channel porous flow plate represents several collector circuits.
Compact micro channel porous flow plate divide into the following categories:
- Two-way;
- Multi-circuit;
- Also, Single-circuit.
Two-way models include special plates with a pair of plug holes. Moreover, these elements change the direction of flow of each agent to the opposite.
In installations of a single-circuit category, the circulation of the coolant itself is easy to carry out in only one direction.
The general view of the activity of units of this type is existing so that the media is easy to direct towards each other. The heating sphere has a direction from the upper part to the lower branch pipe. Furthermore, the cooling flow of compact micro channel porous flow plate makes the same revolution, just the opposite.
According to such basic algorithms, these units perform their work. Differentiation of the basic type consists only in what types of media pass through the housing.
Introduction of Compact micro channel porous flow plate
During long-term operation of heat exchange equipment, scale, mechanical deposits, rust and other contaminants is easy to form. As a result, the performance of the equipment is sharply low, which leads to the need to clean it.
For these purposes, periodic or impulsive flushing schemes are common, where, as a result, the calculate the technical parameters of heat and power devices are restoring. Scale is a heat exchanger's worst enemy.
The liquid that passes through the circuits of the heating unit does not heat up to the mandatory criterion, which, in turn, negatively affects the performance of heat supply and water supply systems.
Heat exchanger cleaning methods
Currently, there are three ways to clean heat exchange equipment. Each type of cleaning depends on the degree of contamination of the unit and the technical parameters of the equipment.
- Mechanical method: However, the principle of mechanical action is common.
- Chemical method: Removal of contamination is carrying out using chemical reagents.
- Combined method: The heat exchange unit is taking to pieces into its component parts, then a chemical type of washing is applying.
Generally, the cleaning option is easy to select considering the technical characteristics of compact micro channel porous flow plate.
Mechanical flushing Compact micro channel porous flow plate
In most cases, this method of cavitation and hydrodynamic flushing is common in industrial plants. The method has an expensive processing segment, since it uses special heat exchange equipment designed for industrial purposes.
Manual method: The peculiarity of this cycle is that all parts of the heat exchanger are completely disassembled. Locksmith tools are common as a tool. Further, using a scraper or a special hard brush, contaminants are removed.
Cleaning is carried out using sandblasting equipment
For a shell-and-tube heat exchanger, complete or partial disassembly of the equipment is envisaged. Cleaning is carried out using sandblasting equipment. Moreover, to clean the dirt on the pipes, use a hollow rod in the form of a drill, cutter, or radial brush.
With a rotary-translational movement, the dirt is cleaned, preliminarily feeding a reagent (flushing liquid) to the cleaning point.
Hydrodynamic jet cleaning: Also, A jet is sent to the place of scale under high pressure, while a little reagent easy to add using an abrasive substance. For flushing, special devices operating under high pressure and technological nozzles are common to form a jet under pressure.
Chemical cleaning of the heat exchanger
In this case, there is no need to disassemble the heat exchanger. With the help of a chemical reagent, rust and scale deposits easy to remove. Also, disassembly of the heat exchanger is not provided. disconnect the heating unit from the main power unit.
Connect the container and the flushing pump; pre-load the chemical reagent into the system. We start up the equipment and carry out flushing within 2-8 hours.
If there is a complex nature of contamination, it can use up to 3-4 types of chemical reagent, and each new reagent provides for the removal of the old chemical composition from the system with rinsing with running water.
Combined method of cleaning heat exchange equipment
The most labor-intensive way to clean compact micro channel porous flow plate is:
- The unit is taking apart into its component parts.
- Also, Parts in baths with the addition of a chemical reagent.
- Moreover, we remove contaminants under the influence of high pressure of a jet of water.
- Furthermore, we assemble the equipment in the reverse order, check the tightness and put the system into operation.
Conclusion
At the final stage, we rinse the system with running water, check for leaks, test the equipment and put it into operation. In the process of heating, calcium salts and magnesium waste settle on the metal surface, and this leads not only to a deterioration in the operation of the equipment, but also to the complete failure of heat exchangers.
