In a specific embodiment, in order to solve the above technical problems, evaporating principle, structure by studying batch still
And the bottleneck in the existing course of work, the relationship of computing device liquid level and volume determine the base in no any previous technological transformation case
It on plinth, courageously breaks through, the distance of tubulation and tank base is promoted, ensureing tubulation at any time all in the base of working media covering
The suitable distance of promotion is strictly calculated on plinth, finally according to the preferred of several schemes, determines to carry tubulation distance from bottom by 100mm
Rise to 500mm.The Pipe bundle structure of batch still, mainly including tube sheet, U-tube beam, baffle plate, pull rod, distance sink tube, slideway, sliding rail,
Support plate etc..Tube sheet horizontal direction increases suspension centre and vertical direction has increased fixed installation structure.Tube sheet is to pass through with U-tube beam
Patch rise+intensity weldering connection.Baffle plate is uniformly distributed on U-tube beam, and tubulation passes through baffle plate；Distance sink tube and pull rod, baffling
The fixed entire tubulation of plate cooperation becomes an entirety.The loading of tube bank and split out container by sliding rail, slideway it is opposite slide it is real
It is existing.After the distance from bottom variation of tube bank, support plate laterally and axially is increased, come when overcoming the dead weight of tube bank and tube bank dismounting
Axial force, i.e. 16 component structures.
After new tubulation promotes 500mm distances, the centre of tube sheet is nearly seated at the top of tubulation, and tubulation length is near
4000mm, to ensure that tubulation levelness and centrad, tubulation and tube sheet are in nature and place unstressed state, to tubulation bottom

Situations such as operating status of sliding rail, considers, and bottom sliding rail is designed as to the relative displacement device of sliding block, slideway.Bottom
Supported design is 16 component structures, and the component structure of every has all fully considered that the axial force of support and lateral force are designed
's.According to tube bank force analysis situation, structure, material, the size of supporting point are determined.
Slideway and 16 points of bottom support, tank skin take integral solder, and the levelness and centrad of support has been effectively ensured,
The levelness and centrad that ensure that tube bank are connect, ensure that the installation quality of equipment.
New tubulation connects the connection mode for rising using patch and being welded with intensity with tube sheet.Such weld seam welding generally takes list
Face double V-groove weld seam welding, for the situation of weld seam material leakage for avoiding occurring in the past, innovation is using the U-shaped groove of single side for the first time
Weld seam welds, i.e. J-type sealing bead.
Dismounting, lifting for convenience of tube bank, are provided with horizontal fulcrum and axial fixing structure, axial restraint point on tube sheet
Setting primarily to when end socket is not installed, tube sheet and tank body can first position fixation, can vacate energy for end socket
Installation.The weld job that support and slideway, tube sheet and tubulation, sliding rail and baffle plate etc. are related in tube bank uses full argon arc welding
Or the welding manner welding in bottom argon arc welding electric welding paving, welding quality has been effectively ensured.
In another specific embodiment, as shown in Fig. 1,3-5, the Pipe bundle structure of batch still includes tube sheet 1, U-shaped row
Pipe 2, distance sink tube 3, baffle plate 4, distance sink tube 5, pull rod 6, nut 7, lateral support plate 8, center brace panel 9, slideway 10, sliding rail
11st, tube sheet fixed structure 12, lifting bolt 13 etc..
1 horizontal direction of tube sheet increases suspension centre and vertical direction has increased fixed installation structure 12, horizontal direction welding suspension centre
Convenient for the position of adjustment tube sheet and end socket sealing surface after tube bank integral hoisting or tube bank lifting；Vertical direction is provided with fixed knot
Structure convenient for tube sheet to the timely fixed tube sheet just after cylinder sealing surface, also saves lifting appliance freely to lift end socket.
Tube sheet 1 and U-shaped tubulation 2 be risen by patch+intensity weldering connects, while the welding groove of tube sheet and tubulation is using single
Face U-shaped groove welding using the welding manner of argon arc welding, reduces the possibility of tube sheet and row official's weld leakage.
Baffle plate 4 is uniformly distributed on U-shaped tubulation 2, and tubulation passes through baffle plate；Distance sink tube 3,5 and pull rod 6,7, baffle plate 4
The fixed entire tubulation of cooperation becomes an entirety.
It the loading of tube bank and splits out container and is realized by opposite slide of sliding rail 11, slideway 10；The distance from bottom of tubulation becomes
After change, lateral support plate 8 and center brace panel 9 are increased, come axial force when overcoming the dead weight of tube bank and tube bank dismounting.
Lifting bolt 13 is that connecting steel wire ropes use when restraining pull-out, and tube bank level is allowed to pull out.
As shown in Fig. 2, slideway is made of slideway bottom plate, slideway baffle, slideway connecting plate, and slideway and lateral support plate 8
With hexagonal angle degree supporting skid rail and tubulation, and it is welded to connect with tubulation 2.And slideway connecting plate is respectively with 135 ° of angles and center branch
Fagging 9 is welded to connect, and center brace panel 9 is mainly used for undertaking the axial force when dead weight of tube bank and tubulation dismounting push-and-pull.Slideway
It mutually moves when bottom plate mainly contacts hand push pulling force with sliding rail 11, also decomposes to tube bank stress in support.Slideway baffle and cunning
Road bottom plate one, principal security tube bank swing when pushing and pulling, and sliding rail does not deviate from slideway.
Therefore, the utility model has the following advantages：The materials such as viscous tar are eliminated to tubulation after new tube bank technological transformation
Viscous wall influences, and effectively improves the evaporation effect of equipment；After tubulation distance from bottom is promoted, tubulation is suspended in batch still liquid level
Portion, when being passed through steam raising, tubulation heat dissipates in the medium to surrounding, the liquid thermally equivalent around tubulation.Medium evaporates
Effect improves, and reduces the waste of steam, and Product recycling utilization rate improves.Compared with original is restrained, ton hexamethylene diamine cost reduction subtracts
The consumption of few 4KG/ tons of hexamethylene diamine raw materials for production adiponitrile.Cycle of operation of batch still extends, batch still continuous operating time by
Original is promoted to 72 hours existing for 48 hours.
Tube bank increases horizontal suspension centre and vertical fixed structure, 16 component supports structures, sliding rail and sliding block in structure
Etc. partial structurtes optimization, the perfect operation reasonability of Pipe bundle structure is easy for installation, ensure that the installation quality of equipment.
This time the technological transformation of tube bank effectively reduces the consumption of raw materials of hexamethylene diamine device, and Product recycling utilization rate and quality carry
Height is made that tremendous contribution to the energy-saving work of device, lays a solid foundation for device Effec-tive Function.
The promotion for the first time of the tube bank upper tube array distance from bottom of tube-sheet heat exchanger, is promoted for later similar technique
With reference to.
