Abstract
The utility model relates to chemical heat exchange equipment, more specifically an enamel glass shell and tube heat exchanger, which comprises a casing, a clamping sleeve, a cover head, a tube plate, and a heat exchange tube. The heat exchange tube penetrates through the tube plate and forms a sealing structure with the tube plate; a tube hole of the tube plate is a sealing box; a sealing member, a pressing ring, and a fastening member, which are sheathed on the heat exchange tube, are orderly arranged in the sealing box. The utility model has the advantages of reasonable structure, convenient sealing operation, and good sealing performance. The utility model is suitable for diversified strong corrosive medium except for hydrofluoric acid and dark phosphoric acid, and can be used for chemical industry, medicine industry, etc.
Description
The utility model relates to a kind of enamel tubular heat exchanger, is used for the heat exchange of deep-etching chemical medium, belongs to the chemical industry equipment field.
The enamel tubular heat exchanger is fixed together by tube sheet and heat exchanger tube, is improved to both and separates, and has realized the purpose that heat exchanger tube, tube sheet can be changed separately, has brought very big convenience to practicality, has very big positive effect., brought another problem, i.e. thereupon the sealing problem between tube sheet and heat exchanger tube, the sealing problem directly affects the serviceability of tubular heat exchanger.Application number is the enamel tubular heat exchanger technology of 95220021.x, sealing property is improved, but, still undesirable, its major defect is: (1) heat exchanger tube adopts two pipe plug-in type welding, and the welding situation influences the heat exchanger apex seal performance, and the wall thickness of heat exchanger tube is thinner, thereby make filler very little to sealing surface amount of movement or expansion amount when compressing, influenced sealing effectiveness; (2) packing seal of this structure, the sealing surface on heat exchanger is axial has become larger-diameter pore sealing surface by the heat exchanger tube peripheral sealing surface than minor diameter, and sealing surface strengthens, and has reduced sealing effectiveness; (3) tube sheet is the hollow-core construction of two outer surface enameling glass, and the wall thickness of steel plate thickness and pore differs bigger, and the clearance distance between two steel plates is bigger again, makes two planes and the pore distortion of tube sheet easily, influences sealing effectiveness.
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the enamel tubular heat exchanger of good seal performance.
Enamel tubular heat exchanger described in the utility model, comprise housing, chuck, end socket, tube sheet and heat exchanger tube, heat exchanger tube passes tube sheet and also and between tube sheet forms hermetically-sealed construction, and the pore of its tube sheet is a seal box, and the seal, pressure ring and the securing member that are enclosed within successively on the heat exchanger tube are arranged in the seal box.
The setting of sealed-box type pore makes sealing property of the present utility model obtain the improvement of essence.The sealed-box type pore can directly process on steel plate when making tube sheet, also can the welded seal box-shaped become on the tube sheet that the pore place is set.Seal such as filler and sealing gasket is bigger to inner sealing surface amount of movement or expansion amount when compressing, and has improved sealing effectiveness; The sealing of this structure sealing surface has in the axial direction become heat exchanger tube peripheral sealing surface than minor diameter by larger-diameter pore sealing surface, has reduced sealing area, has improved sealing effectiveness; Be enclosed within seal on the heat exchanger tube, pressure ring and fixture in the seal box and constitute and compress sealing, the sealing parts are few, and the leak point is few, and good seal performance has reduced the loaded down with trivial details degree of seal operation, and is convenient and easy.
In the utility model:
Tube sheet is stacked by two-layered steel plates and is welded, the equal enamel of surfaces externally and internally.Stability Analysis of Structures, not yielding, can guarantee sealing property; The equal enamel in two sides is beneficial to the enforcement of sealing, and good practical effect is used in the replacing that also is beneficial to the tube sheet two sides.Tube sheet is stacked by two-layered steel plates and is welded, and implements two sides enamel technology easily, and the hydrogen in the enamel process is overflowed along the two-layer slit that stacks steel plate, avoids the burst porcelain image.
The sealing at heat exchanger tube two ends can be adopted above-mentioned identical mode, also the sealing of the heat exchanger tube other end can be taked another way, promptly fixes a face-flange in the other end welding of heat exchanger tube, adds sealing gasket and form hermetically-sealed construction between flange sealing surface and tube sheet.The different seal approach in two ends is used, and simplified structure makes things convenient for seal operation, uses the two sides to ward off tube sheet, can change use when this tube sheet is damaged.
Below in conjunction with the embodiment accompanying drawing the utility model is further described.
The structural representation of Fig. 1, the utility model embodiment tube sheet and heat exchanger tube sealing place.
The sealed structural representation of Fig. 2, the heat exchanger tube other end.
Among the figure: 1,9 tube sheets, 2 seal boxs, 3 sealing gaskets, 4 pressure rings, 5 clamp nuts, 6,7 heat exchanger tubes, 8 sealing gaskets, 10 face-flanges.
As shown in Figure 1, enamel tubular heat exchanger described in the utility model, comprise housing, chuck, end socket, tube sheet 1 and heat exchanger tube 6, tube sheet 1 is stacked by two-layered steel plates and is welded, the equal enamel of surfaces externally and internally, heat exchanger tube 6 pass tube sheet 1 and and 1 formation hermetically-sealed construction of tube sheet, the pore on its tube sheet 1 is a seal box 2, and the graphite grazing pad 3, pressure ring 4 and the clamp nut 5 that are enclosed within successively on the heat exchanger tube 1 are arranged in the seal box 2.
Tube sheet is stacked by two-layered steel plates and is welded, the equal enamel of surfaces externally and internally.Stability Analysis of Structures, not yielding, can guarantee sealing property; The equal enamel in two sides is beneficial to the enforcement of sealing, and good practical effect is used in the replacing that also is beneficial to the two sides.
As shown in Figure 2, the sealing of the heat exchanger tube other end can be taked another way, i.e. the other end of heat exchanger tube welding fixed pan flange 10, at this moment, therefore the whole enamel of the heat exchanger tube that has face-flange, can be added sealing gasket and forms hermetically-sealed construction between flange sealing surface and tube sheet.The different seal approach in two ends is used, and simplified structure makes things convenient for seal operation.The seal approach difference at two ends, when being used, earlier heat exchanger tube is passed two tube sheets successively, and then implements the sealing and fixing operation at an end of heat exchanger tube by mode shown in Figure 1 by mode shown in Figure 2, until seal, sealing gasket is compacted reach seal request till.Flange sealing surface contacts sealing with the face that is sealed into the tube sheet outer surface between tube sheet, and therefore, the two sides that can make the two sides ward off tube sheet is changed serviceability and better brought into play.
The utility model is rational in infrastructure, and seal operation is convenient, good seal performance, good practical effect is applicable to below temperature 200 degree, below the working pressure 0.6Mpa, various strong corrosive mediums except that hydrofluoric acid, SPA can be widely used in industries such as chemical industry, medicine.
