Description
Technical Field
The invention relates to a heat exchanger, in particular to an heat exchange tube spacing maintaining structure.
Background
In addition, the radial reactor is assembled by a process of building a frame and then penetrating the tubes, and the heat exchange tubes are assembled from layers to layers from inside to outside.
Disclosure of Invention
The invention provides spacing maintaining structures for a novel heat exchange tube bundle and an assembling process thereof.
The technical scheme of the invention is as follows:
heat exchange tube spacing maintaining structures are used for a reactor tube bundle, the reactor tube bundle comprises an inner tube and a plurality of heat exchange tubes and comprises a plurality of finger ring sleeves, all the finger ring sleeves surround a plurality of layers of concentric distributed concentric circles, a positioning ring and a plurality of positioning blocks are arranged between every two adjacent finger ring sleeves, the positioning ring sleeves are sleeved on all the finger ring sleeves on the inner layer and fixedly connected with all the finger ring sleeves on the inner layer, the positioning blocks are uniformly distributed on the periphery of the positioning ring and fixedly connected with the positioning ring and correspondingly connected with all the finger ring sleeves on the outer layer, all the finger ring sleeves on the innermost layer are arranged on the periphery of the inner tube and fixedly connected with the inner tube, and the heat exchange tubes correspond to and penetrate through the finger ring sleeves.
The distance ring is a ring body formed by a plurality of sections of circular arcs.
Assembling a reactor tube bundle by using the structure comprises the following steps of , starting from the innermost layers, arranging layers of heat exchange tubes on the outer side of an inner cylinder, sleeving required finger rings on the heat exchange tubes in advance, sliding the finger rings to proper positions, welding the finger rings with spacing rings, adjusting the spacing of the heat exchange tubes in the circumferential direction during welding to enable the heat exchange tubes to be uniformly distributed, assembling a second layer, dividing the mounted spacing rings of the th layer according to the number of the heat exchange tubes of the second layer, marking off dividing lines, welding spacing blocks at the positions of every dividing lines, mounting the second layer of heat exchange tubes sleeved with the finger rings, welding the finger rings on the second layer of heat exchange tubes to the other ends of the spacing blocks, mounting the spacing rings by using the same method as that of the th layer, assembling the rest layers, and mounting the rest layers by using the same method as that of mounting the second layer.
The invention has the advantages of reasonable design and simple structure, and can realize the layered assembly of the heat exchange tubes; the heat exchange tube can be fixed at a certain distance, a channel is reserved for the catalyst, and convenience is provided for loading and unloading the catalyst.
