1. low-temp difference exothermic catalytic gas-solid phase reactor, mainly by shell (P), dividing plate (H), cold tube bag (Cb), support (S), porous plate (R) is formed, shell (P) is a pressure-vessel, the top end socket has air inlet (1), bottom bulkhead has gas outlet (2), dividing plate (H) is divided into top air chamber and bottom reative cell to pressure-vessel, catalyst layer (K) is housed in the reative cell, reative cell bottom bracket (S) supports cold tube bag (Cb), the outer catalyst layer (K) of bottom perforated plate (R) supporting reative cell middle cooling pipe courage, it is characterized in that shell (P) is divided into the end socket (P1) of being with upper flange and the cylindrical shell (P2) of being with lower flange, shell (P) links sealing with dividing plate (H), or dividing plate (H) and the sealing of shell (P) support ring, cold tube bag (Cb) includes air inlet pipe (a), last endless tube (c), cold pipe (b), cold pipe (b) is the U-shaped pipe, and last endless tube (c) links an end of air inlet pipe (a) and the cold pipe of U-shaped (b), and this end of cold pipe becomes descending cold pipe (b A), the other end upper end open of the cold pipe of U-shaped becomes up cold pipe (b B);

  • Perhaps cold tube bag (Cb) includes air inlet pipe (a), last endless tube (c), following endless tube (d), cold pipe (b), and cold pipe (b) is by descending cold pipe (b A) and up cold pipe (b B) form, last endless tube (c) links air inlet pipe (a) and descending cold pipe (b A), following endless tube (d) links descending cold pipe (b A) and up cold pipe (b B);

    Air inlet pipe (a) is passed dividing plate (H) and is used the stuffing-box movable sealing, synthetic raw gas enters the top air chamber by shell (P) napex air inlet, be distributed to each cold pipe (b) through air inlet pipe (a) to last endless tube (c), unstripped gas descending cold Guan Zhongxian flow from top to bottom with cold pipe (b) pipe outside the reaction gas heat exchange, then in up cold pipe from down to up with the pipe outside the reaction gas heat exchange go out up cold pipe to the top, to the pipe outside enter catalyst layer from top to bottom while react with cold pipe in the unstripped gas heat exchange, reaction gas goes out reactor through porous plate by bottom escape pipe (2) to the bottom.
