Abstract
The invention discloses a self-circulating heat exchanger and belongs to chemical equipment. The self-circulating heat exchanger comprises a shell, a low-pressure steam chamber A, a water chamber B, a high-pressure steam chamber C, a first tube plate, a second tube plate, a steam inlet a, a hydrophobic port f, a hydrophobic port d, a tube bundle, a water inlet b, a water outlet c, a drainage port e and a steam-steam ejector 2, and the self-circulating heat exchanger also can comprise a shell, a water inlet chamber A, a steam chamber B, a water outlet chamber C, the second tube plate, the second tube plate, a steam inlet a, a water inlet b, a drainage port f, a water outlet c, a drainage port d, a tube bundle, a hydrophobic port e and a steam-steam ejector 2. The problem of low flow velocity is solved through an ejection mode of the steam-steam ejector. The steam-steam ejector fully utilizes the work doing capacity of steam to facilitate the steam to form high-speed multi-circulation, so that the speed of the steam flowing through a heat transfer surface is improved by several times. A convection heat exchange coefficient is greatly improved, and higher heat exchange quantity is acquired through a smaller heat exchange area. The heat exchanger can be widely applied to heat exchange among water vapor, water and other media.

Background technology
Traditional tubular type vapor-water heat exchanger, no matter vapour is walked tube side is still walked shell side, and the steam acting ability overwhelming majority with certain pressure has been wasted.For the souring that prevents that this acting ability from causing, usually aft cover plate is alleviated on the specialized designs.In a single day steam enter heat exchanger, just slowly flows in the runner of regulation, until flow out with the form of vapour or water.
By the heat convection volume, the coefficient of heat transfer and flow velocity relation are close, and the higher coefficient of heat transfer of flow velocity is larger.So this slow mode that flows of aft cover plate that installs additional is unfavorable to conducting heat; The heat exchange area that requires increases, and has wasted metals resources and the steam kinetic energy energy, has increased production cost.
Summary of the invention
Purpose of the present invention just is to overcome above-mentioned shortcoming and defect, and a kind of self-circulating heat exchanger is provided.It can solve slowly problem of above-mentioned flow velocity, equipment vapour vapour injector takes full advantage of the acting ability of steam self in heat exchanger, impelling steam to form Multiple Cycle at a high speed flows, speed when making vapor stream cross heating surface increases several times, thereby greatly improve convection transfer rate, obtain larger heat exchange amount with still less heat exchange area, thereby reach the saving purpose.
In order to achieve the above object, the present invention proposes the self-circulating heat exchanger of two kinds of structures: a kind of structure is that vapour is walked the tube side formula, and another kind is that vapour is walked the shell side formula.Be described below:
Vapour walk tube side formula self-circulating heat exchanger comprise housing, be installed in the housing the housing inner chamber be divided into low pressure steam chest A and hydroecium B and high pressure steam chest C the first tube sheet and the second tube sheet, be installed in air intake a and drain port f on the low pressure steam chest A, be installed in drain port d on the high pressure steam chest C, be installed in the tube bank that is communicated with low pressure steam chest A and high pressure steam chest C respectively in the hydroecium B, be installed in water inlet b and delivery port c and dewatering outlet e on the hydroecium B.Air intake a is communicated with vapour vapour injector, and the outlet of vapour vapour injector is the Taper Pipe of reduced.Between the first tube sheet and the second tube sheet trunnion is installed, the import and export of trunnion is communicated with low pressure steam chest A and high pressure steam chest C respectively.The Taper Pipe of vapour vapour injector is positioned at the import of trunnion, and the mid portion of restraining among the hydroecium B becomes shell side with baffle interval.
The slow Taper Pipe of the enlarged-diameter that trunnion comprises the large Taper Pipe of reduced, the thin diameter tube that is connected with large Taper Pipe, be connected with thin diameter tube and the pipe that is connected with slow Taper Pipe.
Vapour walk shell side formula self-circulating heat exchanger comprise housing, be installed in the housing the housing inner chamber be divided into intake chamber A and steam chest B and the C of water-supplying chamber the first tube sheet and the second tube sheet, be installed in air intake a and water inlet b and dewatering outlet f on the intake chamber A, be installed in delivery port c and dewatering outlet d on the C of water-supplying chamber, be installed in the tube bank that is communicated with intake chamber A and the C of water-supplying chamber respectively in the steam chest B, be installed in the drain port e on the steam chest B.Air intake a is communicated with vapour vapour injector, and the rear portion of vapour vapour injector is welded on the first tube sheet and with intake chamber A sealing and isolates.The outlet of vapour vapour injector is the Taper Pipe of reduced.The middle part of steam chest B is installed with trunnion, and the import and export of trunnion all is positioned at steam chest B.The Taper Pipe of vapour vapour injector is positioned at the import of trunnion.The mid portion of restraining among the steam chest B becomes shell side with baffle interval, and trunnion is welded on two dividing plates.
Slow Taper Pipe, the pipe that is connected with slow Taper Pipe of the enlarged-diameter that above-mentioned trunnion comprises the large Taper Pipe of reduced, the thin diameter tube that is connected with large Taper Pipe, be connected with thin diameter tube and the enlarging Taper Pipe that is connected with pipe.
Task of the present invention is exactly to finish like this.
The present invention has solved slowly problem of flow velocity with the mode of jet of vapour vapour injector and trunnion.In heat exchanger, vapour vapour injector takes full advantage of the acting ability of steam self, impels steam to form Multiple Cycle at a high speed and flows, and the speed when making vapor stream cross heating surface increases several times.Thereby greatly improved convection transfer rate, obtained larger heat exchange amount with still less heat exchange area, reached the purpose of saving.It can be widely used in the heat exchange between steam and water and other medium.
