Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Wherein identical components are presented with like reference characters.It should be noted that word used in the following description Language "front", "rear", "left", "right", "up" and "down" refer to the direction in attached drawing, word " bottom surface " and " top surface ", "inner" and "outside" refers respectively to the direction towards or away from geometric center of specific component.
A kind of hydrogen from methyl alcohol heat exchanger, as shown in Figure 1, including material inlet portion 1, shell 2 and material outlet portion 3.It is former Material import department 1 connect with the upper end of shell 2, and material outlet portion 3 is connect with the lower end of shell 2；Shell 2 is equipped with heat source import 21 With thermal source outlet 22.
It need to be carried out at high temperature under high pressure when due to methanol decomposition, although traditional plate heat exchanger has biggish heat-transfer surface Product, but its slanting bearing capacity is poor, is easily damaged.Therefore as shown in Figure 1, material inlet portion 1, material outlet portion 3 are designed It is spherical for semicircle, shell 2 is designed as cylinder, just enables to the gas pressure born inside entire heat exchanger so more Add uniformly, local deformation is not susceptible to, to extend service life.
As shown in Fig. 2, being located at itself and material inlet portion 1 (referring to Fig. 1), material outlet portion 3 in shell 2 (referring to Fig. 1) Junction be respectively equipped with cellular board 4 and lower cellular board 5, be provided with several spirals between upper cellular board 4 and lower cellular board 5 and twine Around heat-exchanging tube bundle 6, the both ends of heat-exchanging tube bundle 6 respectively with liquid separation hole corresponding on upper cellular board 4, lower cellular board 5 be connected to.In reality In the production of border, catalyst can be filled to heat-exchanging tube bundle 6, meeting and catalyst when methanol aqueous solution enters in heat-exchanging tube bundle 6 Contact, while extraneous heating system (can be heat-conducting oil system) enters heat source import 21 by heat medium, it is water-soluble with methanol It exchanges heat between liquid.In the shape of a spiral due to heat-exchanging tube bundle 6, the length of tube side is not only extended, while also being changed in shell side The state of heat medium fluid makes fluid that strong turbulence effects be presented, to enhance heat transfer effect；Simultaneously wound heat exchange Tube bank 6 can also effectively eliminate pipe vibration and the stress because of deformation generation of expanding with heat and contract with cold, and extend entire heat exchanger uses the longevity Life.
As shown in figure 3, heat-exchanging tube bundle 6 is by more piece, successively alternate converging transition 61 and divergent segment 62 are constituted, and heat-exchanging tube bundle 6 Wall thickness be 0.6mm~2.5mm.It is scaled by the wall surface of heat-exchanging tube bundle 6, so that stream of the methanol aqueous solution in heat-exchanging tube bundle 6 The variation of the continuous generating period of body pressure, and violent whirlpool wash fluid boundary layer is generated, it is thinned, to enhance The heat transfer effect of tube side feed liquid and shell side heat medium.The tube wall of heat-exchanging tube bundle 6 is relatively thin simultaneously, is not only able to satisfy bearing requirements, but also The heating fluid heat transfer in the raw material and shell side in tube side can be made more abundant.
As shown in figure 3, the inner wall in heat-exchanging tube bundle 6 extends along direction helical ring and is wound with several flow blocking pieces 7, flow blocking piece 7 It is tilted down far from its one end fixed with heat-exchanging tube bundle 6, and tilt angle is 5 °~10 °.Flow blocking piece 7 can expand heat-transfer surface Product, and each flow blocking piece 7 is accordingly to be regarded as a disturbing source, its flow path can be varied multiple times when flowing in heat-exchanging tube bundle 6 in feed liquid, Enhance its turbulence level.Feed liquid can accelerate in the near wall at each flow blocking piece 7 simultaneously, be thinned the thickness of thermal boundary layer Degree, feed liquid and the coefficient of heat transfer of flow blocking piece 7 also will increase.Since entire heat exchanger can expire in the case where overall volume is constant The biggish heat exchange area of foot and excellent heat transfer effect, to save its transport and installation cost.Flow blocking piece 7, which can also enhance, to be changed The whole ring stiffness of heat pipe bundle 6, flow blocking piece 7 can also reduce the pressure drop in heat-exchanging tube bundle 6 diagonally downward, and feed solution flow resistance is not yet It is easily excessive, while can also facilitate and the dirt on its surface is rinsed.When processing flow blocking piece 7, using special purpose machine tool to light Sliding 6 inner wall of heat-exchanging tube bundle extruding makes its molding.
Specific implementation process: the conduction oil in heat-conducting oil system is entered in the shell side of heat exchanger by heat source import 21, Methanol aqueous solution enters from material inlet portion 1 simultaneously, is entered in each heat-exchanging tube bundle 6 by the liquid separation effect of upper cellular board 4, with Cracking reaction can occur with the catalyst in heat-exchanging tube bundle 6 after conduction oil heat exchange, cracking gas is escaped and enter from material outlet portion 3 Subsequent processing, conduction oil are then discharged from thermal source outlet 22.
Embodiment 2: a kind of hydrogen from methyl alcohol heat exchanger, as shown in figure 4, difference from example 1 is that, raw material into Oral area 1 is connect by detachable member 8 with the upper end of shell 2, to facilitate the inner wall of exchange heat pipe bundle 6 (referring to Fig. 3) to be rushed It washes.
As shown in figure 4, the detachable member 8 includes L-type hook 81 and clamping block 82.L-type hook 81 is along material inlet Portion 1 is towards the circumferential uniform array of 2 side of shell, and in the upper end edge of shell 2, its circumferential direction offers the cooperation of several and L-type hook 81 L-type hook slot 23.When the traversing section of L-type hook 81, which is completely in L-type, to be hooked in the traversing section of slot 23, longitudinal sections between the two There are gap, clamping block 82 is embedded in the gap.
Specific implementation process: L-type hook 81 is inserted into along the longitudinal sections that L-type hooks slot 23, rotation material inlet portion 1 makes The traversing section insertion L-type of L-type hook 81 hooks in the traversing section of slot 23, is further filled with clamping block 82, completes material inlet portion 1 and shell 2 installation.It need to only add clamping block 82 to take out when disassembly, then so that L-type hook 81 is detached from L-type and hook slot 23, utilize giant The inner wall of exchange heat pipe bundle 6 is rinsed, so that the dirt formed in heat-exchanging tube bundle 6 is not easy to plug its inside and reduces pressure Drop, the heat exchange efficiency of entire heat exchanger are also not easily susceptible to influence.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.
