Background technology
Tube-type down-flow evaporator has that heat transfer property is good, evaporation intensity is high, evaporation efficiency is high, the advantage such as reliable, firm in structure that operates steadily, and therefore extensively applied in aluminium industry and the chemical industry equipment industry.The tube-type down-flow evaporator of superposed type is made up of heating clamber and the two large divisions of separation chamber up and down, and the steam in the heating clamber shell side carries out undergoing phase transition into condensed water after the heat exchange with the interior solution of tube side.Like Fig. 1, shown in Figure 2; The deriving structure of condensate pipe comprises in the present tube-type down-flow evaporator: superimposed successively up and down heating clamber cylindrical shell 1 and separation chamber's cylindrical shell 2; The lower ends of the water inlet of condensate pipe 3 and heating clamber cylindrical shell 1 is logical; The delivery port 31 of described condensate pipe 3 extend out to outside separation chamber's cylindrical shell 2 in separation chamber's cylindrical shell 2; Condensate pipe 3 between described heating clamber cylindrical shell 1 and the separation chamber's cylindrical shell 2 is a straight pipe type, between the condensate pipe 3 of straight pipe type and heating clamber cylindrical shell 1 and the separation chamber's cylindrical shell 2 all welded seal be fixedly connected.
Because heating clamber cylindrical shell 1 is inconsistent with the thermal expansion amount of separation chamber's cylindrical shell 2; And between the condensate pipe 3 of straight pipe type and heating clamber cylindrical shell 1 and the separation chamber's cylindrical shell 2 all welding be fixedly connected; Therefore the condensate pipe 3 of straight pipe type can't eliminate thermal expansion amount inconsistent and produce in the horizontal direction with the deflection of vertical direction; Thereby cause the weld seam between condensate pipe 3 and heating clamber cylindrical shell 1 and the separation chamber's cylindrical shell 2 to exist bigger local stress; And the solution in separation chamber's cylindrical shell 2 is alkaline solution, and under the working environment of caustic corrosion, weld seam very easily ftractures and causes revealing between condensate pipe 3 and heating clamber cylindrical shell 1 and the separation chamber's cylindrical shell 2; And leak source is inner at evaporimeter, and maintenance also very bothers.
The utility model content
The problem that the utility model need solve be: provide a kind of and can effectively absorb inconsistent and deflection that cause, thereby avoid the deriving structure of condensate pipe in the tube-type down-flow evaporator of condensate pipe weld cracking by the thermal expansion amount of heating clamber cylindrical shell and separation chamber's cylindrical shell.
For addressing the above problem; The technical scheme that the utility model adopts is: the deriving structure of condensate pipe in the tube-type down-flow evaporator comprises: superimposed successively up and down heating clamber cylindrical shell and separation chamber's cylindrical shell, and the lower ends of the water inlet of condensate pipe and heating clamber cylindrical shell is logical; And the condensate pipe of water inlet and the welding of heating clamber cylindrical shell are fixing; The delivery port of described condensate pipe extend out in separation chamber's cylindrical shell outside separation chamber's cylindrical shell, and the condensate pipe between heating clamber cylindrical shell and separation chamber's cylindrical shell is the crooked setting of horizontal S type, and the condensate pipe at delivery port place is bearing in the stuffing box; Described stuffing box sealing and fixing is arranged on the outer wall of separation chamber's cylindrical shell; Be provided with airtight and watertight padding in the described stuffing box, gland is fixedly connected with stuffing box, and gland is pressed on airtight and watertight padding between stuffing box and the condensate pipe outer wall.
Further, the deriving structure of condensate pipe in the aforesaid tube-type down-flow evaporator, wherein, described stuffing box is the annular stuffing box.
The utility model has the advantages that: the condensate pipe between heating clamber cylindrical shell and the separation chamber's cylindrical shell is the crooked setting of horizontal S type; And the condensate pipe at delivery port place is bearing in utilizes in the stuffing box that airtight and watertight padding seals; Inconsistent by heating clamber cylindrical shell and separation chamber's cylindrical shell swell increment like this and deflection that causes just can be absorbed by the elbow part in the condensate pipe; In addition because airtight and watertight padding has flexibility, and condensate pipe can form micro-displacement in airtight and watertight padding, come further to absorb inconsistent and the horizontal direction that causes and the deflection of vertical direction by heating clamber cylindrical shell and separation chamber's cylindrical shell swell increment with this; Thereby effectively avoided the phenomenon of condensate pipe weld cracking to take place.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Like Fig. 3, shown in Figure 4; The deriving structure of condensate pipe in the tube-type down-flow evaporator; Comprise: superimposed successively up and down heating clamber cylindrical shell 1 and separation chamber's cylindrical shell 2; The lower ends of the water inlet of condensate pipe 3 and heating clamber cylindrical shell 1 is logical, and the condensate pipe 3 of water inlet is fixing with 1 welding of heating clamber cylindrical shell, and the delivery port 31 of described condensate pipe 3 extend out to outside separation chamber's cylindrical shell 2 in separation chamber's cylindrical shell 2; Condensate pipe 3 between heating clamber cylindrical shell 1 and separation chamber's cylindrical shell 2 is the crooked setting of horizontal S type; And the condensate pipe 3 at delivery port 31 places is bearing in the annular stuffing box 4, and 4 seal welds of described annular annular packing case are connected on the outer wall of separation chamber's cylindrical shell 2, are provided with airtight and watertight padding 5 in the described annular stuffing box 4; Gland 6 is fixedly connected with annular stuffing box 4, and gland 6 is pressed on airtight and watertight padding 5 between annular stuffing box 4 and condensate pipe 3 outer walls.
In sum; The utility model has the advantages that: the condensate pipe 3 between heating clamber cylindrical shell 1 and the separation chamber's cylindrical shell 2 is the crooked setting of horizontal S type; And the condensate pipe 3 at delivery port place is bearing in the annular stuffing box 4; Utilize airtight and watertight padding 5 to seal, inconsistent by heating clamber cylindrical shell 1 and separation chamber's cylindrical shell 2 swell incremenies like this and the deflection that causes just can be absorbed by the elbow part in the condensate pipe 3; In addition because airtight and watertight padding 5 has flexibility, and condensate pipe 3 can form micro-displacement airtight and watertight padding 5 in, come further absorption and the horizontal direction that cause and the deflection of vertical direction inconsistent by heating clamber cylindrical shell 1 and separation chamber's cylindrical shell 2 swell incremenies with this; Thereby effectively avoided the phenomenon of condensate pipe 3 welds crackings to take place.The leak source of the utility model---the sealing of stuffing-box formula is in outside the tube-type down-flow evaporator in addition; Overhaul very convenient; In service; Even if airtight and watertight padding 5 places find that leakage is arranged, replacing or the encapsulation process that can carry out airtight and watertight padding 5 easily can not cause too big influence to the operation of tube-type down-flow evaporator yet.
