Abstract
The invention discloses a reaction kettle for producing various chemical raw materials by a continuous hydrogenation method. The reaction kettle comprises a cylindrical shell and a pipeline. A reinforcing pipe is welded on the cylindrical shell. The pipeline is fixed on the reinforcing pipe. Before welding of the reinforcing pipe, the reinforcing pipe can be processed according to the external diameter of the welded pipeline, and the welding part of the pipeline also can be machined. Then, pipeline welding strength is greatly reduced. Meanwhile, the welding part is very uniform, thus protecting the pipeline and reducing maintenance difficulty of the reaction kettle. Once replacement is needed due to abrasion, there is no need to arrange holes on the reaction kettle, welding area of the reaction kettle will not be increased, and new leak points also will not be increased. The welding structure of the pipeline on the reaction kettle is suitable for other various types of reaction kettles.
Description
Technical field
The present invention relates to a kind of pressure vessel, relate in particular to a kind of continously hydrogen adding method and produce various industrial chemicals
A kind of reactor.
Background technology
Along with the continuous progress of science and technology, the sorbierite needed for the industry such as chemical industry and pharmacy, xylitol, maltitol and
The products such as furfuryl alcohol are all adopt continously hydrogen adding method to produce, and in the equipment producing this series products, the equipment of core is exactly the most
A kind of reactor, reactor is directly welded with various pipeline, as pipelines such as charging, discharging and catalyst, and factory simultaneously
Family is in order to improve production capacity, and require that the volume of reactor is also increasing, maximum will reach 30m3, and require that operating pressure will reach 10-13MPa in process of production, operating temperature will reach 150-200 DEG C, and this proposes higher wanting to the various pipeline of welding
Ask, require that each welding position must reach designing requirement, do not allow to there is the defect such as crackle and pin hole.This at reactor
There is following shortcoming in the method for upper direct welded pipe line: 1. the size due to reactor is comparatively large, and on reactor, perforate cannot be
Lathe is processed, and therefore opened hole is irregular, more difficult when welded pipe line; 2. once the pipeline of welding occurs that wearing and tearing need
When changing, perforate must be carried out in original welding position, so not only add the difficulty of maintenance, and make the area of welding
Further expansion, occurs that the probability of leakage point can increase.
Summary of the invention
The object of the invention is to provide a kind of reactor novel pipeline connection technique, needs welded pipe line at reactor
The first weld reinforcement pipe in position, then by pipeline welding on reinforced tube, reduce the welding difficulty of pipeline.
The present invention is achieved in that a kind of reactor, comprises cylindrical shell and pipeline, it is characterized in that: at described cylinder
Body is welded with reinforced tube, and described pipeline is fixed on described reinforced tube.
The present invention compared with prior art tool has the following advantages: 1. because various pipeline is welded on cylindrical shell by reinforced tube; reinforced tube can carry out machining before welding; greatly reduce the welding difficulty of pipeline like this; more even in welding position; pipeline is played a protective role, extends the service life of pipeline.2. adopt reinforced tube welded pipe line, reduce the maintenance intensity of reactor, occur that wearing and tearing need to change once pipeline, without the need to perforate again on reactor, as long as is polished in the welding position of reinforced tube and pipeline, the bonding area of reactor would not be increased like this, also can not increase new leakage point.
Detailed description of the invention
A kind of reactor, comprise cylindrical shell and pipeline, cylindrical shell is welded with reinforced tube, pipeline is fixed on reinforced tube.Reinforced tube before welding; can process according to the size of welded outer diameter tube; machining also can be carried out in the position of its welded pipe line simultaneously; greatly reduce the weld strength of pipeline like this; welding position is more even simultaneously; pipeline is played a protective role, extends the service life of pipeline.On this reactor, the Welding Structure of pipeline is adapted on other various types of reactor.
