Cleaning of ventilation systems necessary for normal functioning. They regularly handle large volumes of air, causing the dust, dirt and other precipitation can accumulate on the walls. This reduces the effectiveness of its work, and with a weak bandwidth and completely blocks the circulation of air. Therefore, regular cleaning of ventilation — a mandatory procedure, to ensure the normal operation of this system.
The cleaning of ventilation ↑
Ventilation systems are used for air circulation from the outside. They allow you to keep the premises clean, removing all the dust and dirt flying around. This is especially true for industrial ventilation, which is used in factories or kitchens, but these procedures and in apartment buildings.
Challenges faced by the air purification system is different. Some types are designed to eliminate dust and some against fumes and fats. Therefore, the deposits on the internal walls is different. Depending on them we use different types of cleaning ventilation. This:
- Mechanical method
Mechanical cleaning includes the use of a brushing machine and vacuum cleaner. Effective method with high speed but poorly coping with fatty deposits.
- Chemical method
Is carried out by spraying chemicals in the air duct. It requires complete sealing, because the cleaning products are toxic. The method is fast and efficient, but it requires some preparation.
- The combined method
Also called wet. Combines the previous methods are carried out alternately. It has a high price and requires a lot of time, but the cleaning efficiency is high.
- Blasting
Costly method, which consists in using soda or dry ice. Under the action of compressed air, particles of matter fly into the vent at high speed, crashing into the dirty wall. At the same time it creates an explosion, destroying the coating on the parts, but without hurting herself. Takes a lot of time and requires sealing of the system, but effectively cope with the dirt on the walls.
These methods are used depending on the destination drawing, technical possibilities and client’s wishes. Most often used combined with mechanical cleaning, which gets rid of dust or an oily residue. Other methods relevant with a strong and complex contaminations where simple tools have low effectiveness.
Equipment for cleaning of ventilation ↑
For the procedures for cleaning ventilation, use special equipment. It allows you to separate the dirt from the walls and eliminate it from the system air duct. This applies to:
- Vacuum cleaner
- Brushing machine
- Blaster for dry ice
- Cleaning chemicals and sprays
They are needed for different cleaning methods, but often have complete professional teams in service.
The first equipment — vacuum cleaner. This is a special setting that is appended to the output ventilation hole and sucks up all the dirt, separated from the walls during cleaning. It eliminates the result of work from the system, removing out not only dust and dirt but also the means used in the works.
Brushing machine is used for mechanical cleaning system. This is a small moving unit, which is placed in the duct and removes dirty plaque from the walls. Calculated only on the dust, as the fat quickly clogs fiber brush.
Blaster for dry ice is used in the procedure of blasting. It is a unit for supplying the dry ice and spray. Ice is supplied under high pressure process similar to sand blasting cleaning.
Means for chemical cleaning and spraying devices used for the chemical and combined method. It is a special substance, otslaivayutsya dirt from the walls and Deplete fats. The procedure is fast and effective for work in kitchens and factories.
But the equipment is not complete. Pre-specified need for services, the analysis of ventilation and other preparatory procedures. Only after passing this master with the right set of equipment and substances suitable for the task.
How to perform ventilation cleaning with his own hands ^ a
Cleaning ventilation includes several stages that allow you to restore the state of the duct normal. This process can be carried out independently, using the appropriate equipment. For this purpose the following stages:
- Aerodynamic testing or videospace.
- Preparation for work.
- Cleaning ventilation.
- Check the result.
The first two stages are preparatory and are interchangeable. They are conducted to determine the state of ventilation and the extent of its contamination. Aerodynamic test gives accurate information about the capacity of the duct and the degree of contamination. Videospace same is carried out using a special apparatus equipped with a video camera. This gives you the opportunity to see the condition of ventilation, possible blockages (with uneven pollution), damage to the duct and the type of dirt. On the basis of these tests is determined by the method and intensity of cleaning, as well as additional procedures. In an apartment building it is better to use the aerodynamic test.
Work preparation — the second stage. It includes insulation of the duct, the preparation of the necessary equipment and reagents. The technique used for cleaning, depends on the technique used, therefore, the preparation process may vary. For example, chemical cleaning involves the complete isolation of a segment of ventilation, being in the mechanical method, it is not necessary.
The next step cleaning the ventilation. Necessary reagents and equipment are placed in the duct, begins the process of removing dirt and plaque. Its duration depends on the chosen method and degree of purification. If cleaning the ventilation is carried out with your hands, it is better to use a conventional mechanical method. It is the most simple and cost-effective.
Check result — final stage of the work. It includes inspection of ventilation and other tests to ensure that no untreated plots. After that, all equipment is removed, ventilation returns to operation.
In addition, when cleaning of ventilation used another type of works — disinfection. It is necessary when mechanical methods and includes a complete disinfection of the duct. Because of different spores, bacteria and other microorganisms can exist in ventilation systems, causing harm to others. This is especially true in kitchens, in damp warehouses, and hospitals. Often disinfection is carried out independently of the other stages of cleaning. But their hands disinfection to spend much more difficult than the cleaning of ventilation.
Documentation when cleaning ventilation ↑
Cleaning ventilation is a necessary procedure which promotes its normal functioning. Therefore, the frequency of such work indicated in the Rules of fire safety of the Russian Federation, namely in paragraph 50. He States that such work should be carried out at least 1 time per year. As for medical institutions, where this procedure must be carried out every six months for intake of the mines and once a month for the air chambers.
Therefore, the cleaning procedure of such systems is important and must be approved by the official organizations or the providers of such services. When self-cleaning is carried out appropriate tests confirming the quality of the work performed. In addition, this area is documentation, namely:
- The types of work that are performed when inspection or cleaning.
- Chart audit and cleanup.
- The act of cleaning it audit.
The act may be accompanied by the results of the verification of ventilation effectiveness and acceptance of the system. To make the documentation extremely important, because she will need when checking fire inspection, if the house is used some organization or company.
The importance of cleaning ventilation ↑
The ventilation cleaning is an important procedure that should be carried out periodically. It will improve the efficiency of the duct and increase its service life. Different methods are used, depending on the places of work (hospitals, kitchens, public places, warehouses and the like) and the composition of plaque on the inner walls of ventilation systems. They differ in effectiveness, cost and duration of the work, but the choice should be made deliberately.
Clean the ventilation required to pass fire safety, and medical institutions at all mandatory, because it affects the health of patients and staff. So do not neglect this.
