Description
Technical field
The present invention relates to a kind of condenser of ammonia water absorbing refrigerator, especially a kind of condenser of gravitational force refluxing type ammonia water absorbing refrigerator.
Background technology
Condenser is the equipment that utilizes cooling water that the ammonia of ammonia water absorbing refrigerator rectifying column outlet is carried out condensation.
Because ammonia water absorbing refrigerator needs rectifier unit, has two kinds of methods to provide rectifying required backflow ammoniacal liquor usually, promptly interior the backflow and exteenal reflux.The former is provided with segregator at the rectifying column top, and the latter tells a part of ammoniacal liquor to deliver in the rectifying column from condenser, needs usually to carry with an ammonia pump in addition.
Summary of the invention
The present invention seeks to simplify structure of condenser, improve the efficient of condensation heat transfer process, reduce the manufacturing cost of condenser.
The present invention adopts horizontal shell-and-tube heat exchanger structure, comprises housing, heating surface bank; Housing is made up of cylinder section, left end socket and right end socket; The left end of cylinder section is provided with first flange and left tube sheet, and right-hand member is provided with second flange and right tube sheet; Left side end socket is made up of first end socket and the 3rd flange, and right end socket is made up of second end socket, the 4th flange and demarcation strip; Above-mentioned cylinder section is connected with left end socket with the 3rd flange by first flange, and cylinder section is connected with right end socket with the 4th flange by second flange; On the right end socket cooling water inlet and coolant outlet are set, supporting leg is set on the cylinder section, the top of housing is provided with the ammonia import, and the bottom of housing is provided with the bottom liquid capsule, and the bottom liquid capsule is provided with the ammoniacal liquor outlet; Heating surface bank is divided into heating surface bank, following heating surface bank, and the two ends of each heat-transfer pipe are inserted and be welded in the pore of left tube sheet and right tube sheet respectively; It is characterized in that between heating surface bank and the following heating surface bank catch tray being set, housing is provided with side liquid capsule, and side liquid capsule is communicated with catch tray, and liquid capsule bottom in side is provided with the outlet of backflow ammoniacal liquor.
Compared with prior art, the present invention has following advantage:
(1) the present invention adopts the exteenal reflux mode that catch tray is set in condenser to supply rectifying required ammoniacal liquor, can save a segregator, because this is cooling water (seawater) heat exchanger that needs regularly clean, thereby has simplified system flow and handled easily;
(2) because the catch tray position is higher, can utilize the required backflow ammoniacal liquor of gravity supply rectifying, save an ammonia pump; Because the shared ratio of the liquid measure of condensing that catch tray is collected is fixed, can guarantee suitable reflux ratio automatically simultaneously.Thereby can raise the efficiency, reduce cost and operating cost.
