Abstract
The utility model discloses a heat exchanger, which comprises a shell and a steam drum. Sleeves are arranged in the shell and the sleeve rows consisting of sleeves with different numbers are arranged in the shell so as to form a heat transfer component, and a liquid inlet pipe and a liquid outlet pipe are arranged in the sleeves. The lower part of the liquid inlet and outlet pipe is connected with the liquid inlet header of the lower part, the upper part of the liquid inlet and outlet pipe is connected with the liquid outlet header of the upper part. The liquid outlet header of the upper part is fixed on the shell and is connected with the steam drum through a pipeline. A downcomer is arranged between the steam drum and the liquid inlet header of the lower part, and a blowdown header is arranged on the liquid inlet header of the lower part. An upper fire box is arranged on the upper part of the shell. The utility model has simple structure, can be made, arranged, maintained and used conveniently, has small hot-gas resistance, causes no thermal stress, has long service life and low production cost, has wide application range and is an ideal heat exchange device in the chemical industry.
Description
Technical field: the utility model relates to a kind of heat exchanger, particularly a kind of heat exchanger to industrial hot gas waste heat recovery.
Background technology: the existing heat exchanger in this field is mainly based on fire-tube type, waterpipe type and heat pipe-type, but all exist the gas flow cross-sectional area little, resistance and thermal stress are big, pipe is fragile, and be difficult for changing, the manufacturing cost height, service life is short, operating temperature range is little, and installation and maintenance are defective such as inconvenience extremely.
Summary of the invention: the purpose of this utility model just is to overcome weak point of the prior art, provides a kind of simple in structure, and the fabrication and installation maintenance is easy to use, and the hot gas resistance is little, does not have thermal stress, the heat exchanger of long service life.
The purpose of this utility model is to realize like this, it comprises: housing, drum, be provided with sleeve pipe in the housing, the sleeve pipe of varying number is formed sleeve pipe row and is contained in composition heat transfer element in the housing, be provided with the liquid in-out pipe in the sleeve pipe, the bottom of liquid in-out pipe links to each other with bottom feed liquor header, the top of liquid in-out pipe links to each other with top fluid header, top fluid header is fixed on the housing and by pipeline and drum and joins, be provided with downspout between drum and the bottom feed liquor header, bottom feed liquor header is provided with the blowdown header, and the top of housing is provided with fire-box.
The purpose of this utility model also can realize by following technical measures, sleeve pipe and liquid in-out pipe weld together by end cover, the liquid in-out pipe is positioned at the back side of lower linked box airflow direction, and sleeve pipe row carries out anticorrosion antiwear in the surface and handles, and last fire-box is provided with inspection manhole.
Compared to existing technology, the utlity model has simple in structurely, fabrication and installation maintenances is easy to use, and the hot gas resistance is little, does not have thermal stress, long service life, advantage such as production cost is low, and is applied widely.
