Description
, . ,
Изобретение относитс к теплоэнергетике и может быть использовано йа промышленноотопительных электростанци х и котельных с вакуумными деаэраторами.The invention relates to a power system and can be used in industrial heating power plants and boilers with vacuum deaerators.
Известны способы регулировани группы параллельно работающих деаэраторов путем изменени греющего пара по сигналу общего регул тора давлени и путем регулировани Подачи деаэрируемой мсидкости 1. При этом подача пара в деаэраторы осуществл етс из общей магистрали без учета возможнрго отклонени давлений в разных деаэраторах, что снижает экономичность и эффективность деаэрации .There are known methods for regulating a group of parallel deaerators by changing the heating steam by the signal of the general pressure regulator and by adjusting the Feed of deaerated steam 1. At the same time, steam is supplied to the deaerators from the common main without taking into account the possible pressure deviation in different deaerators, which reduces the economy and efficiency deaeration.
Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс способ регулировани группы параллельно работающих деаэраторов со сливом деаэрируемойжидкости в общую емкость путем изменени подачи греющего пара в каждый деаэратор при изменении давлени в нем и регулировани подач51 деаэрируемой жидкости 2. Однако при таком способе качество деаэращт несколько пониженное.The closest to the invention in technical essence and the achieved result is a method of controlling a group of concurrent deaerators with a drain of deaerated liquid into a common container by changing the supply of heating steam to each deaerator when the pressure in it changes and regulating the flow 51 of deaerated liquid 2. However, with this method, the quality of deaerated liquid somewhat reduced.
Цель изобретени - повышение качества деаэрации. Дл достижени этого дополнительно измер ют уровень жидкости в общей емкости, и регулирование подачи;деаэрируемой жидкости осуществл ют на группу деаэраторов при отклонении измеренного уровн .The purpose of the invention is to improve the quality of deaeration. To achieve this, the level of the liquid in the total tank is additionally measured, and the regulation of the supply; the liquid to be deaerated is carried out on a group of deaerators with a deviation of the measured level.
На чертеже дана схема реализации способа.The drawing is a diagram of the implementation of the method.
Деаэраторы 1 соединены параллельно по входу и выходу и подключены к источнику деаэрируемой жидкости через клапан 2, регулирующий уровень в общей емкости 3 по сигналам .датчика 4 уровн и регул тора.5. Греющий пар подаете через клапаньГб,регулирующие давление.в каждом деаэраторе пЪ сигналам датчиков давлен 7 и регул торов 8.Deaerators 1 are connected in parallel in the inlet and outlet and connected to a source of liquid to be deaerated through a valve 2, which regulates the level in the total tank 3 according to the signals from the level 4 sensor and the regulator. Heating steam is supplied through the valve Gb, which regulates pressure. In each deaerator pj, the signals of the sensors are pressurized 7 and the regulators 8.
Греющий пар подаетс в отдельные деаэраторы через индивидуальные регулирующие клапаны , св занные с регул торами давлени , учитывающими индивидуальные особенности каждого деаэратора, что обеспечивает качественную деаэрацию в каждом деаэраторе, а, следовательно, и во всей группе.Heating steam is supplied to individual deaerators through individual control valves associated with pressure regulators that take into account the individual characteristics of each deaerator, which provides high-quality deaeration in each deaerator, and, consequently, in the entire group.
