Deaerators vacuum DV-150 used to remove from the feed water in steam boilers and feed water in heating systems, corrosive gases, i.e. oxygen (O2) and carbon dioxide (CO2).

Deaerators vacuum DV-150 are manufactured according to TU 3113-004-28903910-2014. OKP code 31 1371.

DV-150 – vacuum deaerator, where 150 – nominal capacity (t/h).

Deaerator vacuum DV-150 used

with the cooler flash steam HNS-16M;
with water jet ejectors: EV-100, EV-220
Nominal capacity of the vacuum deaerators – water flow, consisting of main flow, which is subject to de-aeration (i.e., supplied to the deaerator on the top plate) and steam condensed in the deaerator. The flow of coolant, i.e., superheated water, held deaeration – par performance is not included. And if you use the condensate as a coolant is returned from the production, his flow is credited in the performance of the deaerator.

Vacuum deaerator DV-150 is a complex technical device, including two-stage scheme deaeration of water: 1st jet, 2nd - bubbling where applicable nepravilna perforated plate. Water intended for deaeration, the tube is fed to the upper plate of the deaerator, which is designed so that at minimum load (30%) involved only some of the holes in the inner sector, while increasing the load utilized and the rest of the hole.

In all possible cases, and any change in the load to avoid distortions at the hydraulic water and steam allows partitioning of the upper plates of the deaerator, which ensures the steaming jets of the incoming water.

Overcoming jet stage treatment, the water flows in the bypass plate that is designed to collect and bypass passing the deaeration of water directly on the initial segment that is below the bubble plate. In this plate there is a hole in the form of a sector whose one side is adjacent to a vertical solid wall, heading down to the bottom of the vent housing column.

Next, by-pass plates, the water is directed to a bubble plate with multiple rows of holes, which are oriented perpendicular to the flow of water. To this plate adjacent the overflow threshold, passing to the lower base of the vacuum deaerator.

The water then passes through a bubble plate, flows over the threshold, which falls in the sector that framed partition and the threshold, and eventually is discharged through a special pipe from the deaerator.

Under the bubble plate of the steam (heating medium). Then the water boils, after falls in the region where the pressure is below atmospheric, thereby forming a plate like a steam pillow. And the residual water that remains after boiling is carried on vodoprovodno pipe bubbler on the plate, where, together with the original flow of water is processed. Passing through the holes in the plate pairs barbotirovat water. With the increase in steam flow and, consequently, the increase of load rises the height of the steam cushion, which through the bypass pipe to the bypass bubbler plates excess steam is bypassed. Further, steam passes through the neck of the overflow plate and follows in the jet compartment in which a large part of condenseries. Then the steam-air mixture is given directly to the chiller flash steam HNS-16.
