Degassing is ... How degassing of water is done. Methods of degassing

Degassing is the process of removing from somewhere(usually from air or liquids) of harmful gases and toxic substances. Can be produced both chemically and mechanically. In the first case, usually, solutions of various kinds of degassing substances are used. In this way, the quality of drinking water, industrial oil, etc. can be improved. This method often involves processing the premises after accidents at industrial enterprises and the air in the mines is purified.

What is degassed for drinking water

Removing from the water all sorts of harmful gases can notonly to make it harmless to health, but also curative: for example, with frequent angina it is necessary from time to time just rinse with her throat. At the same time you can heal the gums and clean your teeth. It is believed that degassed water is useful for those who want to lose weight. It is also used for watering plants, and yields are higher.

The method of Alexey Labasa

Degassing of water in our time is most often carried out by the method of Alexei Labasa, invented by him in 1989. The process consists of the following stages:

  1. The water is heated until air bubbles begin to emit (84-86 aboutC.), and do not bring it to a boil.
  2. Next, the pan is removed from the fire and sharply quenches the liquid under a flowing stream of cold water. In this case, the latter is not allowed to enter the vessel.

As a result of all these manipulations, water of a particular crystal structure is obtained. In its useful properties, it somehow resembles a natural thaw.
Several ways to improve its qualities have been developed.

Methods for improving the characteristics of degassed water

degassing of water

So, degassing is a process, as a result of which a certain amount of gases are removed from water, and it acquires special properties. Improve the healing qualities of such water in several ways:

  1. Special properties of silver are used. Any object from this metal is placed in a container for a long time with water already prepared in accordance with the foregoing method. Of course, for everyday use it is not good. Drink "silver" water courses for 7 days with a break of 2-3 weeks.
  2. Degassing of water can also be carried out withpre-freezing. As a result, a medicinal liquid is used, used for the treatment of digestive diseases. At the same time take tap water and defend it for 3 days. Then it is filtered and placed in the refrigerator for freezing. After the water has completely turned into ice, it is removed, heated and sharply cooled.

Degassing of liquids by ultrasound

Since degassing is primarily removalfrom the liquid of harmful volatile substances, this procedure can be performed and by means of ultrasound. This method is very often used due to its cheapness and speed. The essence of it is as follows.

ways of degassing

In any liquid, there are always smallgerminal gas bubbles. Under the influence of ultrasound, they begin to vibrate. In this case, the bubbles increase in size, since they absorb all the gas dissolved in the water. This process causes them to rise to the surface and dissolve in the surrounding air. At the moment, there are the following methods of degassing by ultrasound:

  1. The most effective cavitation. This method uses large-size converters that consume a lot of electricity (up to 10 kW).
  2. The precreditation method is carried out using simpler equipment (uncooled converters), consuming a minimum of electricity (about 0.1 kW).

degassing of oil

Degassing of oils

First, the foaming of the oilinfluence of vacuum). At the end of this procedure, a certain amount of air remains in place. To remove the degassing continue. Degassing of oil is used to remove air from it and prevent rapid oxidation. This operation is considered quite important. A similar method is used, for example, to improve the performance of transformer oil. In this case, the content of air bubbles leads to a decrease in the electrical strength of insulation installations, since they generate electrical discharges. For the treatment of oils, usually, a vacuum degassing unit is used. The process in this case consists of two stages:

  1. In the second stage, the oil is poured in a thin layer for additional diffusion under the influence of a vacuum.
  2. In the third stage, heating of the insulation means is carried out and a higher vacuum pressure is used.

Degassing of mines

Degassing of mines is called a special process of output toThe surface of mine gas and air-gas mixture by collection and suction. In this case, a system of pipelines and drilling wells is used. This reduces the flow of methane from the coal seams into the mines. In addition to the pipes, the degassing systems of the mines consist of regulating, protective and recording equipment, degassing units, control devices and drives.

degassing of mines

Improvement of methods for removing harmfulvolatile substances allowed to create new techniques and methods for the development of coal seams. There was an opportunity of passing methane extraction. Currently used in three ways of degassing of mines:

  1. Removal of methane from reservoirs under development. Parallel wells are drilled and connected to a network of gas pipes laid in mines.
  2. Degassing of adjacent layers with their preliminary unloading from rock pressure. At the same time, part of the methane passes into a free state.
  3. Cleaning of the cavities. Such spaces are pre-fenced with airtight plates and bridges. Further, with the help of gas pipelines, a conclusion is made to the surface of methane-rich air.

Degassing is a process of extraordinary importance,whether it is cooking medicinal water, improving the properties of oil or removing harmful substances from mines. In the latter case, depending on how carefully the operation is performed, the mine's productivity depends, and sometimes the life and health of the workers.
