Abstract
The invention discloses a method for mounting a central tube base of a reforming reactor, and the method is used for solving the problem that the levelness cannot be ensured when a central tube base of a reforming reactor in the prior art is mounted and relates to the field of mounting of petrochemical equipment in the mechanical industry. The method disclosed by the invention comprises the following steps, fixedly connecting one ends of an inverted chain I2, an inverted chain II3 and an inverted chain III4 onto a central tube base 5 respectively, fixing the other ends of the three inverted chains on a lifting hook 1, adjusting the inverted chains so that a port of the central tube base 5 is perpendicular to the ground, and then enabling the central tube base 5 to slowly descend by a crane through the lifting hook 1; when being away from a mounting position by a certain distance, adjusting the inverted chains to ensure that the central tube base 5 keeps horizontal, then pulling the three inverted chains to enable the central tube base 5 to horizontally and slowly descend, adjusting the azimuth of the central tube base 5 when approaching the mounting position, and mounting after the azimuth is appropriate. The method disclosed by the invention is also applicable to other large-size equipment having a strict requirement on levelness during mounting. The method disclosed by the invention has the advantages of rapidness and accuracy in mounting, high efficiency, flexibility and convenience in operation and low cost, and the used equipment is simple.
Description
Technical field
The present invention relates to petrochemical equipment installing area, relate in particular to the installation of reforming reactor.
Background technology
Catalytic reforming process is the important process in oil refining and petrochemical industry, and the appearance of CONTINUOUS REFORMER technology more makes catalytic reforming technology that revolutionary breakthrough has occurred.Four-in-one continuous reforming reactor is the key equipment of continuous catalytic reforming technology, and there are various parts its inside, and pipe core base is one of them.If the verticality of pipe core is bad, can cause catalyst distribution inhomogeneous, not etc., flow is just not different yet, finally affects reaction effect in the pressure drop of oil gas when the beds.Traditional installation method is: use crane lifting pipe core base to adjust its levelness to device interior installation place again, during installation because levelness and perpendicularity deviation need installation and adjustment repeatedly, waste time and energy, easily make the internals damage of mutually colliding with, and be difficult to guarantee the verticality of pipe core.
Summary of the invention
Technical problem to be solved by this invention is innovation reforming reactor pipe core foundation mounting method, guarantees the levelness after pipe core floor installation, prevents that internals from colliding with mutually.
Reforming reactor pipe core foundation mounting method of the present invention: one end of jack I 2, jack II 3,4 three jacks of jack III is fixedly connected on respectively on pipe core base 5, the other end is fixed on suspension hook 1, adjusting jack makes pipe core base 5 ports perpendicular to ground, then with crane, pass through suspension hook 1 by pipe core base 5 slow decreasings, if can be by pulling three jacks while running into other internals of reforming reactor inside in decline process, change the angle of pipe core base 5, avoid the collision with internals; When being equipped with certain distance apart from installation position, adjust jack and make after pipe core base 5 maintenance levels, then pull three jacks to make the horizontal slow decreasing of pipe core base 5 simultaneously, while arriving installation site soon, adjust pipe core base 5 orientation, after orientation is suitable, install.
This installation method is equally applicable to other main equipments that need to be strict with levelness when mounted.
The present invention has the following advantages:
While 1, installing, pipe core base levelness and orientation are easily adjusted, and install quick and precisely, and labour intensity reduces greatly, and has improved working efficiency.
2, use equipment is simple, flexible and convenient operation, and cost is low.
3, avoided the damage of colliding with of internals in reforming reactor.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
In figure: 1-suspension hook 2-jack I 3-jack II 4-jack III 5-pipe core base.
Embodiment
Below in conjunction with accompanying drawing explanation the specific embodiment of the present invention.
With reference to accompanying drawing 1, one end of jack I 2, jack II 3,4 three jacks of jack III is fixedly connected on respectively on pipe core base 5, the other end is fixed on suspension hook 1, adjusting jack makes pipe core base 5 ports perpendicular to ground, then with crane, make suspension hook 1 slow decreasing, if can change the angle of pipe core base 5 by pulling three jacks while running into other internals of reforming reactor inside in decline process, thereby avoid the collision with internals; When pipe core base 5 slow decreasings are when being equipped with certain distance apart from installation position, adjusting jack makes after pipe core base 5 maintenance levels, pull again three jacks to make the horizontal slow decreasing of pipe core base 5 simultaneously, while arriving installation site soon, adjust pipe core base 5 orientation, after orientation is suitable, install.
Claims (2)
1. reforming reactor pipe core foundation mounting method, it is characterized in that: one end of jack I (2), jack II (3), (4) three jacks of jack III is fixedly connected on respectively on pipe core base (5), the other end is fixed on suspension hook (1), adjusting jack makes pipe core base (5) port perpendicular to ground, with crane, pass through suspension hook (1) by pipe core base (5) slow decreasing, if can be by pulling three jacks while running into other internals of reforming reactor inside in decline process, change the angle of pipe core base (5), avoid colliding with internals; When dropping to while being equipped with certain distance apart from pipe core base (5) installation position, adjusting jack makes after pipe core base (5) maintenance level, pull again three jacks to make the horizontal slow decreasing of pipe core base (5) simultaneously, fast arrival is adjusted pipe core base (5) orientation during installation site, after orientation is suitable, installs.
2. reforming reactor pipe core foundation mounting method as claimed in claim 1, is characterized in that: be also applicable to the main equipment that other need to be strict with levelness when mounted.
