(54) ТЕПЛОВОЙ ДВИГАТЕЛЬ(54) THERMAL ENGINE

Изобретение относитс к паросиловым установкам,а именно к двигател м конструктивно объединенным с котлами и конденсаторами, и может быть использовано в качестве привода в транспортных силовых установках малой мощности.The invention relates to steam power plants, namely, motors structurally integrated with boilers and condensers, and can be used as a drive in low power transport units.

Известен тепловой двигатель, содержащий корпус с размещенными внутри него сборником конденсата с парогенератором , турбинным колесом, конденсатором и направл ющей трубкой дл подачи рабочего тела на турбинное колесо. Теплова энерги , подводима к рабочей жидкости в парогенераторе , преобразуетс в данном двигателе в механическую энергию при стекании образук цегос в конденсаторе конденсата на турбинное колесо D.A heat engine is known, comprising a housing with a condensate collector placed inside it with a steam generator, a turbine wheel, a condenser and a guide tube for supplying the working fluid to the turbine wheel. The heat energy supplied to the working fluid in the steam generator is converted in this engine into mechanical energy when the condensate condensate is drained into the turbine wheel D.

Недостатком данного двигател в .л етс его низкий КПД, св занный, с малой эффективностью процесса преобразовани тепловой энергии в механическую при низкопарном течении конденсата на рабочее колесо.The disadvantage of this engine is its low efficiency, due to the low efficiency of the process of converting thermal energy to mechanical energy with low steam flow of condensate to the impeller.

Цель изобретени - повьппение эффективности теплового двигател .The purpose of the invention is to increase the efficiency of the heat engine.

Указанна цель достигаетс тем, что рабочее колесо теплового двигател установлено между направл ющей трубкой и конденсатором, а сборник конденсата разделен на две зоны перегородкой с обратным клапаном, через которую проходит направл юща трубка , причем нижн зона сборника конденсата соединена с парогенератором.This goal is achieved by the fact that the impeller of the heat engine is installed between the guide tube and the condenser, and the condensate collector is divided into two zones by a partition with a check valve through which the guide tube passes, with the lower zone of the condensate collector connected to the steam generator.

Такое выполнение устройства обеспечивает повьшение эффективности про5 цесса преобразовани тепловой энергии в механическую вследствие повьшени параметров рабочего тела перед турбиной .Such an embodiment of the device provides an increase in the efficiency of the process of converting thermal energy into mechanical energy due to the increase in the parameters of the working fluid in front of the turbine.

Claims

The engine includes a housing I, made in the form of a vertical cylinder, the lower part of which serves as a condensate collector. Vertical tube 2 located in the housing, the lower open part of which is lowered into the condensate collector, and the upper part is equipped with a nozzle 3 located in the upper part of the condenser 4 the turbine wheel 5, as well as the steam generator 6 located in the lower part of the housing. The condensate collector is divided into two chambers by a transverse partition with a check valve 7. The upper chamber 8 is connected to the condenser A, and the lower 9 - pipe 10 with a steam generator 6. The engine operates as follows. The liquid working fluid (for example, water), the filling volume of the steam generator 6, evaporates and overheats when supplying the Body Energy to the steam generator 6 from any source (flue gases, solar radiation, etc.). The steam from the steam generator 6 flows out into the lower chamber 9 and expands. Under steam pressure, the valve 7 is closed and the liquid portion through the tube 2 is ejected from the lower chamber 9 onto the blades of the turbine wheel 5. After displacing all the liquid from the lower chamber 9, the steam enters is condensed, the pressure in chamber 9, the steam generator 6 and the condenser 4 is equalized. In this case, the valve 54 7 opens, collecting the liquid in the upper chamber 8, flows into the lower chamber 9 and fills the volume of the steam generator 6. Then the working cycle repeats. Installing a turbine wheel between the guide tube and the condenser and separating the steam generator from the condenser by a partition with a non-return valve allows increasing the pressure of fluid flow to the turbine wheel, as well as increasing the efficiency of the heat engine. Claims of Invention A heat engine comprising a housing with a condensate collector placed inside it with a steam generator, a turbine wheel, a condenser and a guide tube for supplying the working fluid to the turbine wheel, which is different in that the impeller is located between The condensate collector is divided into two zones by a partition with a return valve, through which the guide tube passes.
