Abstract
A distributor with an anticorrosive lining for a heat exchanger, the flat tube plate being provided with a projection which is connected to the tube plate and is formed by a deposit of welding material which acts as an edge for connecting the tube plate to the distributor cylinder, the connection between the anticorrosive linings of the tube plate and the cylinder being achieved by a ring of anticorrosive material having an essentially rounded-off L-shaped cross-section which is attached to the connection. A modified exemplary embodiment is also provided.
Description
The present invention relates to a kind of costly applied corrosion resistant lining that has, the new type heat exchanger distributor of titanium for example, in this distributor, applied corrosion resistant lining rises from flat fully tube sheet, in the engagement range between described tube sheet and distributor cylinder, can reach and have the continuity that the applied corrosion resistant lining of minimum necessary resistant material was concentrated and used to minimum stress.And have maximum reliability and a least cost.
In present technology, the known applied corrosion resistant lining that has high value that various types is arranged is such as the distributor of the heat exchanger of titanium.
In one of these known patterns, use the columniform tube sheet in U-shaped cross section, wherein flat and column type wall is concentrated to prevent stress for joint radially, thereby cut is preferably arranged.But the shortcoming of this tube sheet is in the operation of the basic detonation flame spraying of the titanium of applying ointment or plaster, and its sidewall reflects blast wave causes on most of circumference of the described tube sheet that had not used many faults.Its consequence is the tube sheet that needs to use larger diameter, thereby makes distributor do greatlyyer, and its cost is higher.
Described shortcoming has obtained overcoming in the distributor of the heat exchanger that has applied corrosion resistant lining of another kind of pattern, it is an additives that this plate is welded to the distributor cylinder and accepts the resistant material auxiliary member with the flat fully tube sheet of a band cannelure to obtain.
Still there is the joint between plate and cylinder in the latter's solution, because described cannelure and by the minimizing of it described tube sheet cross section that causes, aggravated the shortcoming that stress is concentrated, this has caused reducing reliability and for onesize distributor, for the described cannelure of filling, demand to titanium material at high price is bigger, thereby has increased cost.
The objective of the invention is by a kind of applied corrosion resistant lining that has high price is provided, such as the distributor of the heat exchanger of titanium to get rid of described shortcoming, in this distributor, the continuity of the applied corrosion resistant lining in flat tube sheet and distributor between cylinder guarantees to have the resistant material of the concentrated and minimum necessity of minimum stress.
Achieve this end, no longer in tube sheet, drive cannelure, and the welds joint that between described tube sheet and distributor cylinder, forms, circumferential section at tube sheet, provide the boss an of necessity by piling up scolder, in addition, be to be that the annulus of resistant material in the L shaped cross section of band fillet is realized in the continuity of joint applied corrosion resistant lining by a cross section, this ring fully sticks on the abutment and near the inner surface of described joint.
Therefore, the distributor that has the heat exchanger of applied corrosion resistant lining comprises a tube sheet and a distributor cylinder, both are by the method for detonation flame spraying resistant material lining, described material is removed with the circumference area that described cylinder engages at described tube sheet, according to the present invention, the feature of this distributor is, circumference area at the no described applied corrosion resistant lining of described tube sheet is provided with a boss, this boss and described tube sheet radial engagement, and form by stacked solder, for between described tube sheet and described cylinder, forming solder joints, the annulus of resistant material in the L shaped cross section of a band fillet fully affixes to described welds joint and sticks on inner surface near the distributor of described weld, and the applied corrosion resistant lining of the described tube sheet of this ring belt fillet ground joint and the applied corrosion resistant lining of described cylinder.
Pack in the distributor cylinder for the ease of the annulus that this class is had the resistant material in L shaped cross section, according to another feature of the present invention, the diameter of described annulus is less than the diameter of described cylinder, and the shoulder ring of a resistant material inserts between the face corrosion lining of the annulus of band fillet in described L shaped cross section and described distributor cylinder.According to the pattern of having improved of the present invention; the annulus of the resistant material in the L shaped cross section of described band fillet is formed by inserting a plurality of secter pats that weld together behind the distributor cylinder, and described weld is by being protected with its lower member cover that has welded together.According to preferential embodiment of the present invention, described resistant material is a titanium.
Will be more clear with reference to following accompanying drawing the present invention, the preferential embodiment that only provides in the mode of non-limiting example that these illustrate it in these embodiments, all can not leave the technical of category of the present invention, structural or technologic modification.
In described figure:
Fig. 1 is at profile longitudinally according to the distributor of heat exchanger of the present invention;
Fig. 2 be one of Fig. 1 in detail part amplification longitudinal sectional drawing;
Fig. 3 is the perspective view that has amplified, and expression is according to the embodiment of the annulus in the L shaped cross section of of the present invention one band fillet that has improved.
With reference to these accompanying drawings, cylinder 1 and a flat fully tube sheet 5 that the distributor of heat exchanger is sealed by circular end-blocking 2 are formed, end-blocking and cylinder are all correspondingly by using corrosion resistant titanium lining 3 and 5 coverings that detonation flame spraying is applied ointment or plaster, the lining 6 of being applied ointment or plaster by detonation flame spraying is arranged on the tube sheet 5, and have a plurality of pipes 7.Described tube sheet 5 is in the same place with 10 butt welding in circumference area 9 separately at weld 8 with described cylinder 1, states titanium lining 6 and 3 in this place and is removed respectively.For this purpose, on the circumference area 9 of described tube sheet 5, form a boss 11 that is become by stacked solder, it is connected (see figure 2) with described tube sheet, and this projection is as the edge of described weld 8.A corresponding boss 12 is also formed by stacked solder in the circumference area 10 of cylinder 1, the titanium ring 13 in L shaped cross section that is connected by a band fillet of the titanium lining 3 of cylinder 1 and 6 of the titanium linings of tube sheet 5 forms, and the two ends of this ring are welded on the parts that are positioned at below it.
Yet, for the ease of described ring 13 is put into described cylinder 1, as providing among the figure, the diameter of described ring is less than the diameter of cylinder, a shoulder ring 14, also be made of titanium, insert between the titanium lining 3 of L shaped ring 13 and described cylinder 1, so described L shaped ring 13 is welded to respectively on the titanium lining 6 and described titanium ring 14 of tube sheet 5.Well-known in titanium engineering field, must be with inert material 15 and 16, such as silver, aluminium etc. insert in respectively between stacked solder thing and the titanium lining.
According to be shown in improvement among Fig. 3 pattern; the titanium ring 13 in the L shaped cross section of described band fillet is made up of 17,18 and 19 3 secter pats respectively, when these secter pats are put into cylinder 1; be welded to each other together, relative weld 20 is by corresponding total cover cap 21 protections.
