Description
Technical field
The utility model belongs to chemical glass lining device, is applicable to the heat exchange of various corrosivity materials.
Background technology
To some corrosivity material, the heat exchange pipe external surface of enamel heat exchanger needs the sintering enamel, between enamel and the tube sheet to be connected sealing unsatisfactory, split porcelain easily, service life is shorter.The heat exchanger tube of enamel heat exchanger adopts slice structure at present, and heat exchange efficiency is low, maintenance cost height, quality instability.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of enamel double pipe heat exchanger, is convenient to install, dismantles, makes simply, long service life.
Enamel double pipe heat exchanger of the present utility model, comprise housing, tube sheet, heat exchanger tube, heat exchanger tube is installed on the tube sheet, it is characterized in that described heat exchanger tube is connect by outer tube and interior pipe box to constitute, and interior pipe two ends are all uncovered, one end is fixed on the dividing plate in the sealing cap and is communicated with inlet water tank in the sealing cap, be connected with water inlet on the inlet water tank, the other end is inserted into the outer tube bottom, the sealing of outer tube bottom, openend is fixed on the tube sheet and is communicated with water tank in the sealing cap, and water tank is connected with delivery port.
Heat exchanger tube of the present utility model is a bushing type, and cooling medium such as running water can be recycling, and the dividing plate in interior pipe and the sealing cap adopts general metal material, and is fixing more convenient.Cooling medium enters from interior pipe, enters water tank from the cavity between interior pipe and the outer tube then and discharges.Sleeve type structure is convenient to realize only handling being tightly connected of tube sheet and heat exchanger tube at an end of heat exchanger, makes processing, makes simply, satisfies the making requirement of enamel heat exchanger tube.
Tube sheet contacts a sintering enamel or has the tetrafluoro layer with material in housing, heat exchanger tube outer tube sintering enamel, the connected mode of heat exchanger tube outer tube and tube sheet is: the sealing surface of tube sheet and heat exchanger tube outer tube is designed to the tapering sealing surface, the openend of corresponding heat exchanger tube is a reducing frustum shape, closely cooperate together with the tube sheet sealing surface, outer tube passes tube sheet and is fixed on the tube sheet outer surface by nut.When sintering enamel of tube sheet contact material, must be added with the tetrafluoro packing ring with the sealing surface place of outer tube.Being tightly connected of this syndeton mode heat exchanger tube and tube sheet is more firm, withstand voltage, is not easy to split porcelain.According to the pressure size, determine the tapering and the degree of depth of tube sheet and heat exchanger tube.When a certain heat exchanger tube is damaged, can only change this root separately, do not influence whole use.
Advantage of the present utility model:
1, tube sheet is only handled one anticorrosion and tapering sealing surface and is got final product, and other parts adopt common carbon steel material, pass the heat exchanger tube outer tube and the tube sheet of tube sheet and fix by nut, make easy for installation.
2, can install, dismantle, change each root heat exchanger tube separately, use cost is low, and quality is easy to guarantee long service life.
3, tapering is adopted in the sealing of heat exchanger tube and tube sheet, makes the withstand voltage 1.6Mpa of reaching of heat exchanger tube, satisfies maximum operating temperature and the following manufacturing technique requirent of 1.6Mpa that glass-lined equipment allows use.
4, heat exchanger tube is a bushing type, and cooling medium such as running water can be recycling, reduces use cost.Heat exchanger is only at one end handled being connected and fixed of tube sheet and heat exchanger tube, makes to make simply.
5, install can be vertical also can be horizontal.
6, do not influence heat-transfer surface.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an I enlarged drawing among Fig. 1;
Fig. 3 is an II enlarged drawing among Fig. 1.
Among the figure: pipe 6 delivery ports 7 tube sheets 8 charging apertures 9 heat exchanger tubes 10 chucks 11 chuck delivery ports 12 vertical installation discharging opening 13 horizontal installation discharging opening 14 horizontal mounting bracket 15 housings, 16 vertical mounting bracket 17 chuck water inlet 18 nuts, 19 enamels or tetrafluoro layer 20 solder joint 21 outer tubes 22 tapering sealing surfaces in 1 water inlet, 2 inlet water tanks, 3 dividing plates, 4 water tanks 5
The specific embodiment
As Fig. 1, the same prior art of whole occupation mode of the utility model heat exchanger both can vertically be installed, and also can horizontally install, backing positions, charging aperture, discharging opening position view when there is shown vertical, the horizontal installation, same prior art.Still can design chuck 10 on the housing, improve heat exchange effect.
Sintering enamel in the housing 15, the housing two ends have sealing cap, and the upper end sealing cap is connected with housing by tube sheet 7, the upper end sealing cap is divided into the two parts that do not communicate, and a part is an inlet water tank 2, and another part is a water tank 4, inlet water tank 2 is brought the mouth of a river 1 into, and water tank 4 is taken the mouth of a river 6 out of.The spray of tube sheet 7 inner surfaces and material contact-making surface, be coated with tetrafluoro layer 19 (perhaps sintering enamel, this moment, the connection sealing surface with the heat exchanger tube outer tube must be added with sealing gasket), the hole of a plurality of installation heat exchanger tubes 9 of processing on the tube sheet, taperings are expanded in these holes.Heat exchanger tube 9 is socketed to form by interior pipe 5 and outer tube 21, and interior pipe 5 communicates uncovered up and down, outer tube 21 outer surface sintering enamels, and the bottom sealing, openend is designed to reducing frustum shape, is convenient to cooperate with the tapering sealing surface 22 of tube sheet 7.As Fig. 1, the openend reducing of heat exchanger tube outer tube 21 is to be welded together by the tubule on top and the extra heavy pipe of bottom, and solder joint 20 forms the frustum shape with the pipe of reducing up and down.During installation, pipe 5 one ends are fixed on the interior dividing plate 3 of sealing cap in the heat exchanger tube, and be communicated with inlet water tank 2, it is fixing by nut 18 at the outer surface of tube sheet that outer tube 21 passes tube sheet 7, the reducing frustum on the outer tube and the tapering sealing surface 22 of tube sheet closely cooperate, during dismounting heat exchanger tube outer tube, nut is opened, extracted out outer tube and get final product.
The heat exchanger lower end can add sealing cap, also can be made into one with housing, and the heat exchanger tube bottom can be fixed, and also can not fix, and in the time of fixedly, adds a tetrafluoro plate and gets final product.
During use, the cooling medium running water enters inlet water tank 2 from water inlet 1, flows into pipe 5 in the heat exchanger tube, flows out from the outlet of interior pipe 5, is back to water tank 4 by the cavity between interior pipe and the outer tube, discharge by delivery port 6, and reusable edible.
