Abstract
The utility model discloses a heating sink, in particular relates to an alkaline medium heating sink in aluminum oxide production. The alkaline medium heating sink comprises a sink body (3) and a heating pipe (2). A support (1) is arranged in the sink body (3) and the heating pipe (2) is wound on the support (1). The alkaline medium heating sink can ensure that the steam performs sufficient thermal transmission on the medium to be heated and finally the steam is discharged from a condensate outlet. In the overall process, the medium to be heated can be heated well and also the sufficient heat exchange can be performed between the steam and the medium. The alkaline medium heating sink has simple structure, few welds, reduces the probability of stress corrosion, can be conveniently mounted, has favorable heating effect and saves energy.
Description
Technical field
The utility model patent relates to a kind of heating tank, relates in particular to the alkaline medium heating tank in a kind of alumina producing.
Background technology
In the aluminum oxide production process, the heating tube of alkaline medium heating tank all is to adopt shell and tube to arrange, as shown in Figure 1, because the shell and tube heating tube is to be the sector structure layout in the center of circle with the groove center, the inner lane circumference will be lacked than the outer ring circumference, must keep certain interval again between the heating tube simultaneously, almost can not place heating tube in groove center portion, the heating of heated medium in the alkaline medium heating tank is inhomogeneous like this, particularly the temperature of groove center part heated medium heated medium all around is low, also do not reach the heating-up temperature of requirement sometimes, heated medium needs the longer time just can reach temperature required, and this has just reduced production efficiency.In addition, because the pipe range of shell and tube heating tube is corresponding shorter, the time of staying of steam in heating tube is also short, and steam was not just discharged from outlet when steam also had abundant condensation, and the heat of steam is not fully utilized, and has wasted the energy.Moreover the welded contact of this structure is many, easily produces stress corrosion and leaks.
The utility model content
Provide a kind of alkaline medium heating tank for solving the problems of the technologies described above the utility model, purpose is to make heating tube energy uniform heating heated medium, makes steam can play heat effect fully simultaneously.
For the utility model that achieves the above object is achieved in that a kind of alkaline medium heating tank, comprise cell body, heating tube, be provided with support in the cell body, heating tube is wrapped on the support.
Described heating tube twines along the support annular and is provided with.
Described heating tube is the single-turn or multi-turn setting.
Be provided with backing plate between described support and the cell body bottom.
Described backing plate is the spill backing plate.
Described spill backing plate is positioned on the cell body inner bottom plating.
Described heating tube is fixedlyed connected with support.
The utility model has the advantages of: the utility model alkaline medium heating tank, steam enters from the heating steam import, flow from top to bottom along heating tube, in whole process, steam carries out heat exchange through the heated medium in heating tube and the cell body, heated medium near cell body carries out heat transmission by the outer ring heating tube, and the heated medium of close core carries out heat transmission by the inner lane heating tube, has so just guaranteed that the heated medium in the whole groove can both be transmitted by heat uniformly.Simultaneously because heating tube is an annular twines, so the flow through distance of steam in heating tube can make steam fully heated medium be carried out heat transmission much larger than the distance of shell and tube heating tube like this.Last steam is discharged from condensation-water drain.Whole process can heat heated medium well, makes steam and medium obtain abundant heat exchange again.This alkaline medium heating tank is simple in structure, and weld seam is few, reduce to produce the possibility of stress corrosion, and is easy for installation, heat effective, energy savings.
Description of drawings
The vertical view of the existing shell and tube alkaline medium of Fig. 1 heating tank.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is a vertical view of the present utility model.
Among the figure, 1, support; 2, heating tube; 3, cell body; 4, spill backing plate; 5, steam inlet; 6, condensation-water drain.
The specific embodiment
Below by the specific embodiment description taken together with the accompanying drawings the utility model is described in further detail, but this is not to be to restriction of the present utility model, those skilled in the art are according to basic thought of the present utility model, can make various modifications or improvement, but only otherwise break away from basic thought of the present utility model, all within scope of the present utility model.
As shown in Figures 2 and 3, the utility model alkaline medium heating tank comprises cell body 3, heating tube 2, is provided with support 1 in the cell body 3, and heating tube 2 annulars are wrapped on the support 1, and heating tube 2 is the single-turn or multi-turn setting, and present embodiment is 2 circles, also can be 1 circle or 10 circles; Be provided with backing plate between support 1 and cell body 3 bottoms, backing plate is a spill backing plate 4.Support 1 is fixedly on the spill backing plate 4; Heating tube 2 is put in cell body inside, is fixed on the support 1; Heating steam enters from heating steam import 5, and condensed water flows out from steam (vapor) outlet 6, the heated medium amount that the number of turns of heating tube and length heat as required, the heating temperature difference and the decision of cell body diameter; Spill backing plate 4 is positioned on the cell body inner bottom plating, so that maintain and replace; Heating tube steam inlet 5 is at the topmost of heating tube; Condensation-water drain 6 is at the foot of heating tube, steam enters from the heating steam import, flow from top to bottom along heating tube, in whole heating process, steam carries out heat transmission through the heated medium of heating tube in cell body, heated medium near cell body carries out heat transmission by the outer ring heating tube, and the heated medium of close core carries out heat transmission by the inner lane heating tube, has so just guaranteed that the heated medium in the whole groove can both be transmitted by heat uniformly.Simultaneously because heating tube is an annular twines, so the flow through distance of steam in heating tube can make steam fully heated medium be carried out heat transmission much larger than the distance of shell and tube heating tube like this.Last steam is discharged from the condensed steam outlet.Whole process can heat heated medium well, makes steam and heated medium obtain abundant heat exchange again.
