Description

(54) ТЕРМИЧЕСКИЙ ДЕАЭРАТОР(54) THERMAL DEAERATOR

1one

Изобретение относитс к теплоэнергетике , в частности к устройствам деаэраторов большой производительности.This invention relates to a power system, in particular, to high capacity deaerator devices.

Известен термический струйный -деаэратор , содержащий цилиндрический горизонтальный корпус с расположенными в нем горизонтальными перфорированными тарелками 1.Known thermal inkjet -deaerator containing a cylindrical horizontal body located in it perforated horizontal plates 1.

Наиболее близким к предлагаемому вл етс термический деаэратор, содержащий цилиндрический- корпус с крыщкой и патрубками подвода воды и отвода выпара, размещенные по русно в корпусе перфорированные наклонные тарелки 2.Closest to the present invention is a thermal deaerator containing a cylindrical body with a lid and nozzles for supplying water and discharge of vapor, which are placed along the perforated inclined plates 2 in the body.

Недостатком известных деаэраторов вл етс ограниченный диапазон регулировани .A disadvantage of the known deaerators is the limited range of adjustment.

Цель изобретени расширение диапазона регулировани .The purpose of the invention is the expansion of the adjustment range.

Указанна цель достигаетс тем, что термический деаЪратор, содержащий цилиндрический корпус с крышкой и патрубками подвода воды и отвода выпара, размещенные по русно в корпусе перфорированные наклонные тарелки, разделен вертикальной перегородкой , установленной между крышкой и нижней тарелкой, на два отсека, каждый изThis goal is achieved by the fact that a thermal deflector containing a cylindrical body with a lid and branch pipes for supplying water and discharge of steam, placed perforated inclined plates along the rail in the body, is divided by a vertical partition installed between the lid and the lower plate into two compartments, each of

которых имеет индивидуальные патрубки подвода ВОДЬ и отвода выпара.which has individual connections for the supply of water and exhaust vapor.

Причем каждый патрубок снабжен регулирующим органом.Moreover, each pipe is provided with a regulatory authority.

На чертеже изображен термический де5 аэратор.The drawing shows a thermal de5 aerator.

Термический деаэратор содержит цилиндрический корпус 1 с крыщкой 2, размещенные по русно в корпусе перфорированные наклонные тарелки 3, причем деаэратор д разделен вертикальной перегородкой 4, установленной между крышкой 2.и нижней тарелкой 3 на отсеки 5 и 6. Отсек 5 снабжен индивидуальными патрубками 7 и 8 подвода воды и отвода выпара, снабженных, соответственно, регулирующими органами 9 15 и 10. Отсек 6 снабжен индивидуальными патрубками 1 и 12 подвода воды и отвода выпара и снабженных, соответственно, регулирующими органами 13 и 14. Кроме того, деаэратор снабжен патрубком подвода пара 15 с вентилем 16.Thermal deaerator contains a cylindrical body 1 with a lid 2, placed perforated in the housing perforated inclined plates 3, and the deaerator d is divided by a vertical partition 4 installed between the cover 2. and the bottom plate 3 on compartments 5 and 6. The compartment 5 is provided with individual nozzles 7 and 8 supply of water and drainage of steam, supplied, respectively, by regulatory authorities 9 15 and 10. Compartment 6 is equipped with individual connections 1 and 12 for water supply and drainage of steam and supplied, respectively, by regulatory bodies 13 and 14. In addition, the deaerator is equipped with a steam supply pipe 15 with a valve 16.

Деаэратор работает следующим образом .The deaerator works as follows.

Claims

The deaerated water through the water supply pipes 7 and 11 with regulating bodies 9 and 13, respectively, enters the coryiyc 1 deaerator on the perforated inclined plates 3 and, the passage through the perforations of the latter, is crushed into jets. At the same time, a certain level of water is established on the perforated inclined plates 3. Heating steam through the pipe 15 with the valve 16 subparts in the lower part of the deaerator housing and passes through compartments 5 and 6, where, condensing on the streams of water flowing through the perforated inclined plates 3, heats and deaerates the latter. The non-condensable gases and the uncondensed vapor are removed from compartments 5 and 6 through the nozzles 8 and 12 of the vapor outlet. When the deaerator mode of operation deviates from the nominal, for example, when the water temperature at the inlet to the deaerator increases, as well as when the pressure of the heating steam increases, the volume flow rate of the heating steam changes. In order to maintain a constant steam velocity, the regulators 9 and 10, located respectively on the nozzles 7 and 8 of the water supply and the outlet of the steam into the compartments 5, are closed. At the same time, the entire amount of water is directed to compartment 6 and on perforated inclined plates 3 of compartment 6, a high level of water is established, and this ensures a uniform distribution of water jets over the cross section of compartment 6, while maintaining the steam velocity in the deaerator , because when the compartment 5 is turned off, the section for the passage of steam is reduced. In this way, the proposed design of the deaerator allows for an optimum ratio of water velocity and steam velocity in the deaerator with a wide range of operating conditions. Claim 1. Thermal deaerator containing a cylindrical body with a lid and nozzles for water supply and evaporation, located along the perforated inclined plates in the body, characterized by the fact that it is divided by a vertical partition installed between the lid and the bottom a plate, on two compartments, each of which has individual branch pipes of a supply of water and removal of vapor. 2. A deaerator according to claim 1, characterized in that each nozzle is provided with a regulatory authority. Sources of information taken into account in the examination 1.
