The invention relates to the heat exchanger technology, in particular to a high-temperature and high-pressure anti-corrosion compound type heat exchanger. The high-temperature and high-pressure anti-corrosion compound type heat exchanger comprises a heat exchange barrel, a titanium material heat exchange pipe, a left pipe plate, a right pipe plate, a left end socket and a right end socket, and is characterized in that the heat exchange barrel is composed of a left heat exchange barrel body and a right heat exchange barrel body; a first titanium covering layer and a second titanium covering layer are arranged on inner bodies of the left heat exchange barrel body and the right heat exchange barrel body correspondingly; the left heat exchange barrel body and the right heat exchange barrel body are connected in a sealed manner through a left flange and a right flange; the left pipe plate and the right pipe plate are titanium-steel double-face compound plates; the first titanium covering layer is welded to a left inner titanium covering layer in the left pipe plate; and the second titanium covering layer is welded to a right inner titanium covering layer in the right pipe plate. The invention aims at designing the high-temperature and high-pressure anti-corrosion compound type heat exchanger low in manufacturing cost and resistant to corrosion. Compared with the prior art, the heat exchanger is of a full-compound structure. All parts meet the technical requirements for high temperature resistance, high pressure resistance and corrosion resistance at the same time, the welding operation is convenient, and the welding quality can be ensured through the structure characteristics.
Description
technical field [0001] The invention relates to heat exchanger technology, in particular to a high-temperature, high-pressure, anti-corrosion composite heat exchanger. Background technique [0002] At present, under the conditions of high temperature, high pressure and strong corrosion environment, the material of the heat exchanger is mainly to choose the corresponding pure metal material or alloy, such as: tantalum, zirconium, nickel, titanium, Inkel alloy, Hastelloy alloy, Monel Alloys and more. A common feature of these materials is that the material price is high and the manufacturing cost is quite high, which limits the selection of equipment under many harsh working conditions. Contents of the invention [0003] The purpose of the present invention is to design a low-cost, corrosion-resistant, high-temperature, high-pressure, anti-corrosion composite heat exchanger. [0004] In order to achieve the above purpose, the present invention adopts the following technica...
