что приводит к потере пара, отсасываемого Бмэсте с воздухом из конденсатора. Цель изобретени  - повышение наде ности и экономичности работы системы путем кс1шючении попадани  воздуха во всасыБающ}ю полость насоса, а также искпюче ни  роста температуры воды в контуре свер допусткмой.; Повышение эконокшчности св зано с ис ключением потери пара и существенным уменьшением расхода циркул ционной БОДЫ8 котора  отбираетс  только дл  охлаждени  воды в контурЗа Это достигаетс  тем, что в верхней час ти второго отсека размещен водораспреде пительный перфорированный лоток, примыкающий к перегородке, а перед всасывающим трубопроводом насоса включен поверхностный тегшообменник. При этом лоток разделен на секции вертикальными листа ми, высота которых уменьшаетс  от пере городки к периферии лотка. На чертеже схематически изоб|зажена замкнута  система питани  водоструйного эжектора Система питани  водоструйного эжектора 1 дл  отсоса пар0 воздушной смеси из конденсатора 2 паровой турбины 3 содер жит сливной бшс 4 дл  сбора циркулирующе в аамклутой системе обессоленной, воды . Вертикальна  перегородка 5 делит бак на два отсека; первый отсек 6 предназначен дл  сброса водО Боздушной смеси после эжектора Ij а второй отсек 7 - дл  сбора водЫо Насос 8 предназначен дл  подачи рабочей из отсека 7 к водоструйному эжектору 1. Перфорированный горизонтальнь5й лоток 9 с вертикальными секционирующими листами 10 прикреплен к перегородке 5 со стороны отсека 7 и служит дл  отделени  воды от воздуха. Поверхностный теплообменник 11, встроен ный во второй отсек 7, предназначен дл  охлаждени  воды в баке« Трубопровод 12 соедин ет напорный циркул ционный водово 13с теплообменником 11 Трубопровод 14дл  слива нагретой в теплообменнике 11 воды соедин ет последний со сливным циркул ционным водоводом 15 конденсатор , 2,, Воздухомер 16 .установлен на патрубке 17 в крышке бака 4 и позвол ет измер ть расход воздуха, отсасываемого из кондекн сатора 2 и сбрасываемого в атмосферу. Регул тор 18 охлаждающей воды в теплообменнике 11 может быть установлен на одном из трубопроводов 12 или 14, В вер ней части отсека 6 предусмотрен Трубопро вод 19 до  сброса 1збытка воды в кондек сатор 2с. Задвижка 20 на трубопроводе 2 отсоса паро всздутиной смеси из конденса тора 2 предназначена дл  подключени  эжектора к последнему. Замкнута  система работает следуюишм образом. Сливной бак 4 заполн ют обессоленной водой. Затем включают насос 8, и во; начинает двигатьс  по замкнутому контуру насос 8 водоструйный эжектор 1 - сливной бак 4 ™ насос 8. Затем организуют подачу охлаждающей воды из напорного водовода 13 к теплообменнику 11, дл  чего включают в работу регул тор 18 или запускают дополнительный насос (на чертеже .не показан). Убедившись в нормальной работе системы, открывают задвижку 20, По воздухомеру 16 определ ют расход отсасываемого из конденсатора воздуха. Пар, содержащийс  в отсасываемой из конденсатора паро-воздущной смеси, конденсирует1с  в эжекторе 1 на струе рабочей воды. По вл ющийс  в св зи с этим избыток воды в замкнутом контуре по трубопроводу 19 сбрасываетс  в конденсатор 2. Расход воды, отбираемый :на теплообменник 11 из напорного циркул ционногв водовода 13 конденсатора, в этом случае в дес тки раз меньше, чем при разомкнутой системе питани . Теплообменник 11 может быть встроен, как изображено на чертеже, в отсек спи&ного бака перед насосом, либо установлен на напорной линии между насосом 8 и эжеКл тором 1. В последнем случае исключаетс  попадание циркул ционной воды в обессоле ную воду, циркулирующую в замкнутом ко туре . Предлагаема  система надежна в эксплуатации и экономична. Формула и 3О бретени  1,Замкнута  система питани  водоструйного эжектора, например, дл  отсоса паро-воздушной смеси из конденсатора паровой турбины, содержаща  сливной бак, разделен ный перегородкой на два отсека, к первому из которых по ходу воды подключен сбросной патрубок эжектора, а ко второму - асасывающий патрубок насоса рабочей воды эжв тора, отличающа с  тем, что, с целью повьпиени  надежносги и экономичности , в верхней второго отсека; раэмещен водораспределительный перфорирова ный лоток, примыкающий к перегородке, а перед всасывающим трубопроводом насоса включен поверхностный теплообменник, 2.Система по п, 1, отличающа с  TOMJ: что лоток разделвн на секЦии вертикальными листами, высота которых уменьшаетс  от перегородки к периферии лотка.which leads to loss of steam, sucked Bmeste with air from the condenser. The purpose of the invention is to increase the reliability and efficiency of the system by ks1 by bleeding air into the suction pump cavity, as well as by increasing the temperature of the water in the water circuit; The increase in economic efficiency is due to the elimination of steam loss and a significant decrease in the flow rate of circulating BODY8, which is selected only to cool water into the circuit. This is achieved by placing a water-perforated perforated tray in the upper part of the second compartment and in front of the pump suction pipe included surface tag exchanger. In this case, the tray is divided into sections by vertical sheets, the height of which decreases from the partition to the periphery of the tray. In the drawing, a closed supply system of a water-jet ejector is schematically depicted. The power supply system of the water-jet ejector 1 for suctioning steam from the air mixture from the condenser 2 of the steam turbine 3 contains a drain bsc 4 for collecting circulating in a steam-free desalted water. A vertical partition 5 divides the tank into two compartments; the first compartment 6 is designed to discharge water; air mixture after the ejector Ij; and the second compartment 7 is for collecting water. The pump 8 is designed to feed the working compartment 7 to the water-jet ejector 1. Perforated horizontal tray 9 with vertical sectional sheets 10 attached to the partition 5 from the compartment side 7 and serves to separate water from air. The surface heat exchanger 11, built into the second compartment 7, is designed to cool the water in the tank. Pipeline 12 connects the pressurized circulating water 13c to the heat exchanger 11 Pipeline 14dl drained from the heat exchanger 11 of the water connects the last condenser, 2, The air meter 16 is mounted on the nozzle 17 in the cap of the tank 4 and makes it possible to measure the flow rate of air drawn from the condenser 2 and discharged into the atmosphere. The cooling water regulator 18 in the heat exchanger 11 can be installed on one of the pipelines 12 or 14. In the vertical part of the compartment 6 the Pipeline 19 is provided up to discharge 1 overflow of water to the condenser 2c. The valve 20 on the pipe 2 suction of the steam-air mixture from the condenser 2 is designed to connect the ejector to the latter. Closed system works in the following way. Drain tank 4 is filled with desalted water. Then turn on the pump 8, and in; pump 8 begins to move in a closed loop; water-jet ejector 1 — drain tank 4 ™ pump 8. Then organize the supply of cooling water from the pressure conduit 13 to the heat exchanger 11, for which the regulator 18 is put into operation or an additional pump is started (not shown) . Making sure that the system is in normal operation, they open the valve 20. According to the air gauge 16, the flow rate of the air drawn from the condenser is determined. The steam contained in the vapor-air mixture that is sucked from the condenser condenses in the ejector 1 on the working water jet. The resulting excess water in a closed loop through pipe 19 is discharged into condenser 2. The flow rate of water taken: to the heat exchanger 11 from the pressure circulating water conduit 13 of the condenser, in this case is ten times less than with an open system nutrition The heat exchanger 11 can be integrated, as shown in the drawing, into the compartment of the back tank in front of the pump, or installed on the pressure line between the pump 8 and the ejector. 1. In the latter case, circulation water does not enter the demineralized water circulating in the closed boiler. round. The proposed system is reliable and economical. Formula and 3O breach 1, Closed supply system of a water-jet ejector, for example, for suction of a vapor-air mixture from a steam turbine condenser, containing a drain tank divided by a partition into two compartments, to the first of which the ejector outlet pipe is connected along the water path the second is an aspiration branch pipe of the working water pump of the end torus, characterized in that, in order to maintain reliability and efficiency, in the upper second compartment; The water distribution perforated tray is adjacent to the partition wall, and a surface heat exchanger is included in front of the pump suction pipe. 2. A system according to claim 1 that differs from TOMJ: that the tray is divided into vertical sheets, the height of which decreases from the partition to the periphery of the tray.
