| 摘要 |
<p>The invention relates to a cooler for low-temperature methanol washing gas, which comprises a first heat exchanger (1) and a second heat exchanger (2). The first heat exchanger (1) comprises a first housing (11), a first board, and a first heat exchange tube (12). The first housing (11) is provided with a first feed gas inlet (g1), a first feed gas outlet (g2), a first heat transfer medium inlet, and a first heat transfer medium outlet. The second heat exchanger comprises a second housing (21), a second board, and a second heat exchange tube (22). The second housing (21) is provided with a second feed gas inlet, a second feed gas, a second heat transfer medium inlet, and a second heat transfer medium outlet. The second housing (21) and the second board of the second heat exchanger (2) may be made with a relatively thin plate, thereby enormously reducing the material and manufacturing cost for the invention with meeting the requirements of the production.</p> |
