Abstract

The invention discloses a multi-purposed heat exchange reaction apparatus consisting of a cylinder (1), a heat source fluid discharge end cover (14), a heat source fluid inlet end cover (3), a heat exchange tube (10), a thermostat (K), a pre-heater (Y), a bottom pipe board (15) and an opening pipe board (2). The apparatus has the advantage of convenience in removal because of the opening pipe board, so that the apparatus can carry integral catalyst and is applicable in occasions with vibration operating condition, etc.; with the thermostat built, the apparatus can not only save bypass pipelines for regulating temperature, but also simplify the control method. The invention has the advantages of compacted structure, even transfer of heat, convenience in compacted design and manufacturing, long service life of the catalyst, easiness and fastness in maintenance, and is in particular applicable to new technical projects, such as locomotive waste heat utilization, following hydrogen making, etc.

Description

Technical field [0001] The invention relates to a multipurpose heat exchange reaction device, which is suitable for various occasions with heat exchange and heat exchange reaction, and belongs to the field of chemical machinery, or especially the field of waste heat application of locomotive internal combustion engines. Background technique [0002] In the chemical machinery of the prior art, both ends of the heat exchange tubes inside the tube-and-tube heat exchange reaction device are welded or expanded on the tube sheet, and the tubes and the tube sheet are in a fixed state. The biggest shortcoming of this tube-and-tube heat exchange reaction device is that in the cavity between the outer wall of the tube and the inner wall of the cylinder of the reaction device, only granular catalysts can be loaded, and monolithic catalysts cannot be used. If this device is applied to occasions with severe vibration conditions, such as waste heat utilization of locomotive engines, etc.,...
