Description

This technical solution relates to domestic heating systems and can be used to remove air from these systems.

Known deaerator [1], containing mounted on the storage tank cylindrical columns, each of which has a water supply pipe. The deaerator is equipped with a separation compartment, which is formed by vertical partitions installed between the columns.

The disadvantage of this deaerator is that it is relatively complex and expensive for domestic heating systems.

A device for removing gas from water [2] is known, including a housing in which pipes with hydrophobic material are located on their inner surface, collectors that combine pipes, inlet and outlet pipes. The collectors are divided into sectors by perpendicular partitions with windows made with the possibility of successive movement of water through all pipes. The inlet and outlet nozzles are in communication with neighboring sectors of one of the collectors.

This device is metal-intensive and difficult to manufacture.

A known vacuum deaerator [3], comprising a housing with a pipe for supplying the source water to be deaerated and a pipe for discharging deaerated water. In addition, on the body there is a pipe for venting the vapor-air mixture. Inside the casing there is a water distributor of the source superheated water.

The specified deaerator operates under vacuum. To create a vacuum, additional vacuum equipment is needed.

Known centrifugal deaerator [4]. It includes a pipe with straight and curved sections. Inside the straight section is a hollow body

rotation with a swirl, in the form of a screw and evaporation with straightening blades.

This device operates under excessive pressure and does not provide, with the use of seals, the retention of steam and air into the environment.

Known thermal deaerator [5], which includes a deaerator column on the deaerator tank with a low-pressure water distribution device located therein with a jet nozzle and a water supply fitting. In addition, a second nozzle is located behind the nozzle, the opening of which is smaller than the opening of the first nozzle.

To separate the air on such a deaerator, a temperature of the working medium close to vaporization is necessary.

Known deaerator [6], containing a vertical hollow body with nozzles. A working head is installed on the housing, combined with a slot in the housing. A separating surface is fixed in the body cavity and is made in longitudinal section in the form of a gable convex divider installed at the outlet of the diffuser channel.

This technical solution is structurally piled up and raises doubts about its performance.

Also, a device is known for separating gas from a liquid [7], including a horizontal housing with a vertical nozzle for introducing liquid and nozzles for the exit of gas and liquid. A curved collector with fiber packing and a drain pipe fixed to the bottom of the collector is attached to the input pipe.

A disadvantage of the known device is the fibrous packing, which over time can decompose and parts of it will spread throughout the system.

All of the above deaerators are difficult to manufacture and expensive.

To eliminate these drawbacks, the task was to create a deaerator of simple design, cheap and reliable in operation.

To solve this problem, a deaerator is proposed, as well as the previous one, including a housing with inlet and outlet nozzles and bottoms.

In contrast to the known, in the inventive deaerator the housing is located vertically. At the top there is a spherical bottom with a fitting. An inlet pipe is attached to the lower bottom, with a displacement of its longitudinal axis relative to the longitudinal axis of the housing. The outlet pipe is located in the lower part of the housing on the opposite side of the fixed inlet pipe. Inside the case, above its half, two perforations are installed that have a distance between themselves.

Distinctive features of the proposed solution have a number of positive properties that affect the technical result, namely:

- the case is located vertically. This allows the body to create a sufficient column of water to separate air bubbles;

at the top there is a spherical bottom. The spherical bottom has no stagnant zones. Therefore, it is most effective in work and in manufacturing;

- the bottom has a fitting. The presence of the fitting provides air exhaust;

- an inlet pipe is attached to the lower bottom, with a displacement of its longitudinal axis relative to the longitudinal axis of the housing. Thus, the path traveled by the jet is increased, compared with if the pipe were installed along the axis of the housing;

- the outlet pipe is located in the lower part of the housing from the side opposite to the fixed inlet pipe. This arrangement ensures the creation of a loop of water flow, while ensuring the separation of air bubbles,

- inside the case, above its half, two perforations are installed, having a distance between each other. Perforation is located under the zone of the reversal of the jet. Thus, the jet passes twice through the perforation holes, which means that there is more grinding of the jet, as a result, more separation of bubbles.

The distinguishing features listed above are necessary and sufficient to solve the task. All the distinguishing features are in a causal relationship with the result, they solve the problem at a high technical level and make it possible to create a deaerator design that has perforation and an unusual arrangement of nozzles.

The essence of the technical solution is explained by the drawing, which shows a sectional deaerator.

The deaerator includes a housing 1 and a bottom 2,3. The upper bottom 2 is spherical with a fitting 4. The lower bottom 3 is flat. An inlet pipe 5 is attached to the lower bottom 3 with a displacement of its longitudinal axis relative to the longitudinal axis of the housing 1. The outlet pipe 6 is located in the lower part of the housing 1 on the opposite side of the fixed inlet pipe 5. Inside the housing, two perforations are installed above its half 7. Perforations are located on distance from one another.

Deaerator works as follows. Inlet 5, under pressure, receives water, which carries air bubbles. For normal operation of the heating system, air bubbles must be removed. For this, the inlet pipe 5 is displaced relative to the longitudinal axis of the housing in the deaerator. Thus, the incoming jet passes through two perforations 7, being divided into many small jets, rotates 180 °. When turning, many jets are under the influence of centrifugal force. Also, the buoyancy force acts in this zone. These two forces add up and, as a result, there is an intensive separation of air bubbles from water. On the reverse

water, separating into small streams, also passes a second time through two perforations 7. The remaining air bubbles are removed. After passing the perforation 7, small trickles are added, the flow of water calms down. At the same time, in the case 1 two oncoming flows move, under different walls. Next, the water laminar flow enters the outlet pipe 3.

The air is separated from the water takes up space above the turning zone of small jets of water and goes into the hole of the nozzle 6.

Thus, the claimed technical solution is efficient, easy to manufacture, non-metal-intensive and cheap. In the manufacture does not require special equipment, equipment and tools. The use of this deaerator in domestic and industrial heating systems will improve the operation of these systems.
