Abstract
A kind of tube-type graphite heat exchanger mouth of pipe seam lining, is characterized in that: seam lining is with the annular flange for limiting intubating length and fixed position.The thickness of seam lining is between 0.001 to 500mm, and the length of seam lining is between 0.001 to 50000mm.In use, lining is pressed into the endoporus of heat exchanger tube sheet and tubulation, and covers the seam of heat exchanger tube sheet and the plastic bonding of tubulation pipe end completely.This lining not only effectively blocks fresh corrosive medium and contacts with the direct of seam crossing consolidating resin, and, effectively can slow down the thermal shock of medium to consolidating resin seam, thus extend the service life of consolidating resin seam.
Description
Technical field
The utility model belongs to tube-type graphite heat exchanger technical field, particularly relates to the design of tube-type graphite heat exchanger mouth of pipe seam bush structure and preparation method.
Background technology
At present, the tube sheet of known Tube Heat Exchanger all adopts the form of plastic bonding to be connected with tubulation pipe end.In using, cementing seam directly contacts with chemical medium, and under strong corrosive medium and alternating temperature-changing produce the dual corrosion effect of impact stress, the easy corrosion cracking of cementing seam causes leakage, causes Tube Heat Exchanger to damage.
Summary of the invention
In order to overcome this outstanding problem of the easy corrosion failure of seam of existing Tube Heat Exchanger tube sheet and the plastic bonding of tubulation pipe end, the utility model provides a kind of tube-type graphite heat exchanger mouth of pipe seam lining, this lining not only effectively blocks fresh corrosive medium and contacts with the direct of seam crossing consolidating resin, and, effectively can slow down the thermal shock of medium to consolidating resin seam, thus extend the service life of consolidating resin seam.
The utility model solves the technical method that its technical problem adopts: install a seam lining additional at the seam crossing of Tube Heat Exchanger tube sheet and the plastic bonding of tubulation pipe end, one section at seam lining is provided with annular flange, the thickness of seam lining is between 0.001 to 500mm, the length of seam lining is between 0.001 to 50000mm, in order to insertion depth that is fixing and restriction liner sleeve pipe, the inside of seam lining can arrange (or not arranging) elastic skeleton as required, to ensure that seam lining to insert after the seam crossing of tube sheet and the plastic bonding of tubulation pipe end the closely swollen inner side being attached to tube sheet and tubulation pipe end, reach the result of use that fresh deep-etching high-temperature medium directly can not contact tube sheet and tubulation pipe end plastic bonding seam.Seam lining can select corresponding material for the characteristic of different chemical mediums, as corrosion resistant metal material or other corrosion resistant engineering plastics, reach the object that the consolidating resin slowing down tube sheet and tubulation pipe end seam crossing is subject to dual corrosion under strong corrosive medium and alternating temperature-changing produce impact stress effect.
The beneficial effects of the utility model are, the dual corrosion that the consolidating resin that slow down tube sheet and tubulation pipe end seam crossing is subject under strong corrosive medium and alternating temperature-changing produce impact stress effect, extends the service life of tube-type graphite heat exchanger under high temperature strong corrosion mixture condition condition.
Accompanying drawing explanation
Fig. 1 is the project organization schematic diagram of the utility model tube-type graphite heat exchanger mouth of pipe seam lining.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
In Fig. 1: 1, heat exchanger graphite tube plate, 2, heat exchanger graphite tubulation, 3, seam lining, 4, glued joint resin, 5, pressing plate.
Detailed description of the invention
In FIG, first heat exchanger graphite tube plate (1) is connected by gum resin (4) cementation solidifying with heat exchanger graphite tubulation (2).Seam lining (3) is inserted the endoporus of graphite tube plate (1) and graphite tubulation (2), and covered the cementing seam of graphite tube plate (1) and graphite tubulation (2), and be coated with corresponding adhesive at graphite tube plate (1) and the bore area of graphite tubulation (2) and the outer surface of liner sleeve pipe (3) and realize the cementing of seam lining and endoporus.Thus blocked direct contact that processing medium and graphite glueds joint resin (4), and slow down processing medium glueds joint resin (4) thermal shock to graphite.The flange position of seam lining (3) is fixing with pressing plate (5) pressurization.
