Abstract
The utility model relates to a heat exchanger for a glass lined sleeve. A heat exchanging pipe uses a sheathing structure. One end of a cylinder body is provided with a water tank, and the opening end of an outer sleeve of the heat exchange pipe is sealed on a pipe plate, and the closed end of the outer sleeve of the heat exchange pipe is fixed to a support plate. The inner side of the pipe plate is provided with a gasket, the outer sleeve is provided with a blocking disk to be pressed tightly with the gasket, and the outer side of the pipe plate is fixed by a nut through a press plate to jointly realize the seal of the outer sleeve and the pipe plate. The pipe plate does not need a lining. The utility model has the advantages of high heat exchanging efficiency, good sealing performance, low cost, long service life and easy fabrication.
Description
The utility model relates to the tubular heat exchanger in the chemical industry equipment.
The enamel tubular heat exchanger is owing to corrosion-resistant, structure compactness, high, the low cost and other advantages of heat exchange efficiency, used widely, Chinese patent 94235973.9 discloses a kind of floating head type enamel tubular heat exchanger, except that having above-mentioned advantage, also have following characteristic: heat exchanger tube adopts inside and outside two-layer sleeve pipe to form, and heat exchange efficiency improves; Heat exchanger tube and tube sheet adopt assembly type, if a certain parts damages, can change separately, prolonged service life or the like, but also there is following deficiency in it: (1) heat exchanger tube inserts tube sheet at interval in cylindrical shell, the tube and tube interbody spacer is big, and the number that heat exchanger tube is arranged is not brought into play maximum, thereby influences area of dissipation.(2) the cylindrical shell both sides all are provided with water tank, and both sides all need tube sheet, and tube sheet needs enamel, and all there is the leak point in both sides.What (3) sealing means of heat exchanger tube and tube sheet was taked is that heat exchanger tube openend flanging is fixed with screw, the one, and the technological requirement height, the flange place is not easy enamel, and burst porcelain easily, thereby influences sealing property and service life; The 2nd, necessary counterenamel causes complex process, the cost height in the hole of tube sheet correspondence; The 3rd, need a plurality of screws to fix, enamel wearing and tearing in screw place are big.(4) blind end of every heat exchanger tube does not have support, is subjected to the influence of the temperature difference, and yielding the causing between pipe of this end collided, worn and torn, and also quickens the burst porcelain phenomenon of the other end, also influenced sealing property.
The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, and provides a kind of more enamel double-tube heat exchanger of excellent properties that has, heat exchange efficiency height, good airproof performance, low, the long service life, easy to manufacture of cost.
Enamel double-tube heat exchanger of the present utility model, comprise cylindrical shell, water tank, tube sheet, many heat exchanger tubes, heat exchanger tube is made up of inside and outside two-layer sleeve pipe, the outer tube outer surface enameling glass, end sealing, inner sleeve inserts its bottom, form cavity between two-layer sleeve pipe, its technical characterstic is: cylindrical shell one end has water tank, and the outer tube openend is sealed on the tube sheet, and blind end is fixed on the gripper shoe.
Above-mentioned water tank is by the vertical separated into two parts of water inlet pipe connecting plate, and water inlet pipe is in fore-end, and outlet pipe is in rear end part, and inner sleeve one end is fixed on the water inlet pipe connecting plate.
The sealing of above-mentioned outer tube and tube sheet is to realize in the following way: there is packing ring the tube sheet inboard, has block plate on the outer tube and packing ring compresses, and the tube sheet outside is fixed with nut by platen again.
Have some discharge openings on the above-mentioned gripper shoe simultaneously, on total bobbin carriage that discharging opening is positioned at cylindrical shell is connected.
Below in conjunction with description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is tube sheet and heat exchanger tube syndeton schematic diagram.
Among the figure: 1 water tank, 2 water inlet pipe connecting plates, 3 inner sleeves, 4 platens, 5 tube sheets, 6 packing rings, 7 block plates, 8 charging apertures, 9 outer tubes, 10 cylindrical shells, 11 gripper shoes, 12 bobbin carriages, 13 total discharging openings, 14 outlet pipes, 15 water inlet pipes, 16 pads, 17 nuts
Cylindrical shell 10, bobbin carriage 12 inner surfaces and outer tube 9 outer surface enameling glass, the inner sleeve 3 of heat exchanger tube is fixed on the water inlet pipe connecting plate 2, water inlet pipe connecting plate 2 makes the vertical separated into two parts of water tank, fore-end is water inlet, rear end part is water outlet, water is entered by inner sleeve, from the cavity that inside and outside sleeve pipe forms, flow out, 1 in water tank is in cylindrical shell 10 1 end settings, the blind end of outer tube is fixed on the gripper shoe 11, gripper shoe does not need enamel, makes with polytetrafluoroethylmaterial material, and some heat exchanger tubes are so arranged.Chemical mediator enters bobbin carriage through heat exchanger tube by the discharge opening on the gripper shoe, is flowed out by total discharging opening 13.Being tightly connected of outer tube and tube sheet is such: tube sheet 5 inboards are monoblock packing ring 6 (corresponding to the perforate of outer tube place), have block plate 7 on the outer tube, the tube sheet outside is monoblock platen 4 (corresponding to the perforate of outer tube place), be fixed by nut 17, preferably add one deck pad 16 between tube sheet and platen, tube sheet need not enamel like this.Remaining part of the present utility model is all identical with existing enamel heat exchanger, as adopting chuck cylindrical shell etc.
Advantage of the present utility model:
1, the arrangement mode of telescopic heat exchanger tube can make changing in the unit volume cylindrical shell The heat pipe number increases, thereby has improved heat exchange area.
2, only in cylindrical shell one side tube sheet is set, has reduced the leak point, improved sealing, The sealing means of outer tube and tube sheet is not easy to damage enamel simultaneously, and good seal performance makes Long with the life-span, technological requirement is low, and tube sheet does not need enamel, cost simultaneously.
3, heat exchanger tube adopts modular construction, can change separately the parts of damage, improves The service life of a whole set of heat exchanger.
4, in light weight, volume is little, can vertical or horizontal use, easy to manufacture, the fortune of moulding The row cost is low, easier promoting the use of.
