Abstract

The invention relates to a tube-pass expansion type single-tube-pass heat exchanger which comprises a barrel (2), a heat exchange tube bundle (4), a barrel sealing box (1) and a tube box (5). A tube-pass outlet fixing connector (13) is arranged on the barrel sealing box (1), the barrel sealing box (1) is connected with the barrel (2) through a fastener, the heat exchange tube bundle (4) is arranged in a shell pass cavity formed by the barrel sealing box (1) and the barrel (2) and comprises a fixed tube plate (6), a heat exchange tube (8), a movable tube plate (9), a floating head (10), a tube-pass expansion joint (11) and a tube-pass outlet connecting flange (12), the movable tube plate (9) is connected with the floating head (10) through a fastener, the floating head (10) is connected with the tube-pass outlet connecting flange (12) through the tube-pass expansion joint (11), and the tube-pass outlet connecting flange (12) is connected with the tube-pass outlet fixing connector (13) through a fastener. The single-tube-pass heat exchanger has the advantages that the tube bundle is detachable, the single-tube-pass heat exchanger is convenient to clean, maintain and replace, and running and manufacturing costs under special working conditions can be saved.

Description

technical field [0001] The invention relates to a single-tube-pass heat exchanger, in particular to high-energy-consuming industries where the temperature difference is large and single-tube-pass high-temperature heat exchange is used. Widely used in chemical industry, metallurgy, electric power and other fields. Background technique [0002] At present, heat exchange equipment occupies a very important position in the petroleum, chemical, and electric power industries. Taking a polysilicon production plant as an example, heat exchange equipment accounts for about 50% of the total metal consumption of the equipment. Heat exchange equipment is not only the main equipment in the process, but also the main means for enterprises to reduce energy consumption and production costs. The technical level of its heat exchange equipment is one of the important symbols of the advanced level of polysilicon production plants. For the occasion of large temperature difference and single-t...
