Abstract
The utility model discloses a graphite heat exchanger, relating to a heat exchanger used on chemical engineering equipment. The utility model is developed mainly for solving the problem a connecting position between a heat exchange pipe and a pipe plate in the existing heat exchanger is easy to crack and leak with short service life, etc. A pipe plate set is utilized, the connecting position between the heat exchange pipe and the pipe plate is provided with a sealing ring and a sealing pad and fastened by screws in order to obtain the aim of seal, and thus the problem that the connecting position between the heat exchange pipe and the pipe plate in the existing heat exchanger is easy to crack and leak is solved.
Description
The utility model relates to the heat exchanger that uses on a kind of chemical industry equipment.
Heat exchanger tube sheet that uses on the chemical industry equipment and heat exchanger tube bond with the phenolic resins clay at present, shortcoming is that heatproof is low, because tube sheet is different with the heat exchanger tube material, the thermal coefficient of expansion difference, seepage easily ftractures in the junction of action of thermal difference lower perforated plate and heat exchanger tube, service life is short, general only about 1 year.
The purpose of this utility model is a kind of structure tube list of design, and is easy to make, do not ftracture easy to leak not, the graphite heat exchanger of long service life under higher temperature and pressure.
The purpose of this utility model is achieved in that heat exchanger upper cover 1 is connected with upper perforated plate group 4, the upper perforated plate group is connected with upper shell 3, the upper shell below is connected with cylindrical shell 5, some heat exchanger tubes 6 and some deflection plates 7 are housed in the cylindrical shell, the cylindrical shell lower end is connected with lower perforated plate group 9 and low head 10, heat exchanger tube passes through in the hole of upper and lower tube sheet group, and water inlet 8 is established in the cylindrical shell bottom, and upper shell sets out the mouth of a river 13.Each tube sheet group of upper perforated plate group and lower perforated plate group is all formed with upper perforated plate by two, establish sealing ring 12 between each piece tube sheet, sealing ring is enclosed within on the heat exchanger tube, force together mutually by tube sheet, fastening with screw, in order to sealing, the tube sheet tubesheet holes diameter that wherein is connected on the heat exchanger tube tube head is identical with the internal diameter of heat exchanger tube, around the hole annular groove is arranged,, and between tube head and tube sheet, establish sealing gasket 11 so that tube head stretches in the groove.
The utility model has the advantages that: simple in structure, easy to make, under higher temperature and pressure, do not ftracture, easy to leak not, long service life generally can be used 3 years, filled up bad to change a underlay just passable, and heat transfer area is big, maintenance and cleaning are convenient.
Accompanying drawing 1 is a generalized section of the present utility model, among the figure: 1. upper cover; 2. flange; 3. upper shell; 4. upper perforated plate group; 5. cylindrical shell; 6. heat exchanger tube; 7. deflection plate; 8. water inlet; 9. lower perforated plate group; 10. low head; 11. sealing gasket; 12. sealing ring; 13. delivery port.
Accompanying drawing 2 is sealing of the present utility model position schematic diagrames, among the figure: 4. upper perforated plate group; 6. heat exchanger tube; 11. sealing gasket; 12. sealing ring.
Embodiment: above cylindrical shell, install cylindrical shell, the tube sheet group is installed in the upper shell top, the upper perforated plate group is made up of three tube sheets, its top dress heat exchanger upper cover, some heat exchanger tubes are installed in the cylindrical shell equably, 3--5 sheet deflection plate is set in the cylindrical shell, the cylindrical shell lower end is connected with lower perforated plate group and low head, the lower perforated plate group also is made up of three tube sheets, heat exchanger tube is from last, pass through in the hole of lower perforated plate group, water inlet is established in the cylindrical shell bottom, and upper shell sets out the mouth of a river, on, each tube sheet group of lower perforated plate group is all formed with upper perforated plate by 2, establish sealing ring between tube sheet and the tube sheet, sealing ring is enclosed within on the heat exchanger tube, is forced together mutually by tube sheet, fastening with screw, the tubesheet holes diameter that is connected on the heat exchanger tube tube head is identical with the internal diameter of heat exchanger tube, has annular groove, tube head to stretch in the groove around the hole and establish sealing gasket between the tube sheet to seal, sealing ring and sealing gasket are made of fluorubber, and tube sheet is warded off tetrafluoro with metal and made.
