Abstract
The utility model discloses a kind of coil arrangement, comprise supervisor and many seamless steel elbows, every root seamless steel elbow is arranged in parallel, and all cross-over connection is arranged between two supervisors, it is characterized in that: on supervisor, corresponding every root seamless steel elbow is provided with circular cylindrical projection pipe, hollow hole in described circular cylindrical projection pipe is connected with the hollow hole in supervisor, and the two ends of described seamless steel elbow are all corresponding welds with the circular cylindrical projection pipe on supervisor.The utility model has the advantages that: overall structure is simple, and the circular cylindrical projection pipe of weld had both made welding operation more convenient, also make that connection is more reliable, sealing is stronger; The bend pipe employing different materials at diverse location place had both efficiently solved the abrasion and corrosion in heating process, also made the manufacturing cost of supervisor low as much as possible, also improve the service life of coil pipe greatly.
Description
Technical field
The utility model relates to a kind of equipment of heating furnace, is specifically related to a kind of coil arrangement.
Background technology
Tubular heater is a kind of directly heated type firing equipment, mainly through the steam radiant heat transfer in coil pipe, by the heating of the material of transport, drying.Coil pipe is the parts directly contacted with heated material, so the quality of coil pipe directly determines the tubular heater efficiency of heating surface, and its life and reliability.The supervisor of existing coil pipe and the welding of seamless steel elbow are directly on the cylinder of supervisor, and make solder side be oval, and not in one plane, stress is large, the sealing property of impact welding on the one hand, affects its service life on the other hand.
In addition, in actual production, because heated material and coil pipe directly contact and relative motion, friction inevitably causes wearing and tearing, and the liquid that heated material carries in addition also can cause corrosion by coil pipe.The problems such as the steam leakage worn and torn, corrode and cause thus become another key factor in restriction tubular heater life-span.The tubular heater of a dry ore does not often use the problem how long just occurring wearing and tearing, steam leakage, thus has to change tube coil.And the process changing coil pipe is complicated, the cycle is long, this seriously constrains the production efficiency of factory, improves the production cost of factory.
Utility model content
The utility model provides a kind of coil arrangement that can improve coil pipe service life for above-mentioned the deficiencies in the prior art.
The technical solution adopted in the utility model is:
A kind of coil arrangement, comprise supervisor and many seamless steel elbows, every root seamless steel elbow is arranged in parallel, and all cross-over connection is arranged between two supervisors, it is characterized in that: on supervisor, corresponding every root seamless steel elbow is provided with circular cylindrical projection pipe, hollow hole in described circular cylindrical projection pipe is connected with the hollow hole in supervisor, and the two ends of described seamless steel elbow are all corresponding welds with the circular cylindrical projection pipe on supervisor.
By technique scheme, the external diameter of described circular cylindrical projection pipe is identical with the external diameter of seamless steel elbow.
By technique scheme, the convex pipe of described cylinder is vertical with supervisor to be arranged.
By technique scheme, described seamless steel elbow comprises seamless steel elbow, the seamless steel elbow of coil pipe zone line, the seamless steel elbow in coil outlets region in coil inlet region, and this trizonal seamless steel elbow is made by different two-phase stainless Steel materials.
By technique scheme, the decay resistance being arranged on the seamless steel elbow in the relative coil inlet region of decay resistance of the seamless steel elbow of coil pipe zone line and the seamless steel elbow in coil outlets region is strong, and the abrasion resistance properties of the seamless steel elbow in coil outlets region is strong relative to the abrasion resistance properties of the seamless steel elbow of coil pipe zone line and the seamless steel elbow in coil inlet region.
The utility model has the advantages that: overall structure is simple, and the circular cylindrical projection pipe of weld had both made welding operation more convenient, also make that connection is more reliable, sealing is stronger; The bend pipe employing different materials at diverse location place had both efficiently solved the abrasion and corrosion in heating process, also made the manufacturing cost of supervisor low as much as possible, also improve the service life of coil pipe greatly.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated.
As Figure 1-3, present embodiments provide a kind of coil arrangement, comprise supervisor 1 and Duo Gen seamless steel elbow 2, every root seamless steel elbow 2 is arranged in parallel, and all cross-over connection is arranged between two supervisors 1, on supervisor 1, corresponding every root seamless steel elbow is provided with and is responsible for perpendicular circular cylindrical projection pipe 3, hollow hole in described circular cylindrical projection pipe 3 is connected with the hollow hole in supervisor 1, the external diameter of described circular cylindrical projection pipe 3 is identical with the external diameter of seamless steel elbow 2, the two ends of described seamless steel elbow 2 are all corresponding welds with the circular cylindrical projection pipe 3 on supervisor, what both made welding operation become is simple, also make the interface of welding circular by elliptical deformation, make the sealing of welding, reliability strengthens greatly.
In the present embodiment, seamless steel elbow comprises seamless steel elbow, the seamless steel elbow of coil pipe zone line, the seamless steel elbow in coil outlets region in coil inlet region, this trizonal seamless steel elbow is made by corrosion-resistant, that abrasion resistance properties is different stainless steel tube, adapts to the material-to-be-heated of different pH values and hardness respectively.Wherein, the decay resistance being arranged on the seamless steel elbow in the relative coil inlet region of decay resistance of the seamless steel elbow of coil pipe zone line and the seamless steel elbow in coil outlets region is strong, and the abrasion resistance properties of the seamless steel elbow in coil outlets region is strong relative to the abrasion resistance properties of the seamless steel elbow of coil pipe zone line and the seamless steel elbow in coil inlet region.So, improve life of product, reduce production cost simultaneously.
The composition that the ore raw material that each manufacturer buys contain is different, coil pipe life-span on equipment can only use about 5 ~ 6 months, the most long life also can only at about 12 months, and the existing transformation being used different materials by segmentation, the life-span has used more than 42 ~ 72 months.
The material that originally coil pipe uses is Unite States Standard 31803, uses now domestic, is divided into every section of different two phase stainless steel (316L, 2205,2507).
