Abstract
The utility model discloses a hydrogenation reaction kettle manufacturing various chemical raw materials using the continuous hydrogenation method. The kettle comprises a cylinder body, a steam conduit, a spherical upper end plate, and a spherical lower end plate, wherein, the steam conduit is fixed at the periphery of the inner side of the cylinder body through a bracket, the spherical upper end plate and the spherical lower end plate are fixed at two ends of the cylinder body, a discharge port is formed on the upper end plate, a feed port is formed on the lower end plate, and the cylinder body is made up of a stainless steel inner cylinder and a carbon steel outer cylinder. Besides the advantage of greatly reducing the cost of manufacturing the reaction kettle, the utility model is widely used in such industries as chemical engineering, pharmacy and the like, for manufacturing products such as sorbitol, xylitol, maltitol, furfuryl alcohol and the like.
Description
Technical field:
The utility model relates to a kind of pressure vessel, relates in particular to the reactor that a kind of continously hydrogen adding method is produced various industrial chemicals.
Background technology:
Along with continuous progress in science and technology, the required products such as sorbierite, xylitol, maltitol and furfuryl alcohol of industry such as chemical industry and pharmacy all are to adopt the continously hydrogen adding method to produce, the equipment of core is exactly hydrogenation reaction kettle the most in the equipment of producing this series products, manufacturer is in order to improve production capacity simultaneously, require the volume of reactor also increasing, maximum will reach 30m
3Require operating pressure will reach 10-13MPa in process of production, operating temperature will reach 150-200 ℃, the reactor of therefore general carbon steel and enamel structure can not satisfy the demand of production, must adopt stainless steel cauldron, if but reactor all adopts the stainless steel manufacturing, its cost is very high, and general manufacturer can not accept; Owing to want continously hydrogen adding and steam heated in process of production, this sealing to reactor has proposed requirements at the higher level in addition.
The utility model content:
The utility model purpose is to provide a kind of hydrogenation reaction kettle of new structure, and the method that adopts stainless steel and carbon steel to combine is produced reactor, greatly reduces the manufacturing cost of large-scale hydrogenation reaction kettle.
The utility model is achieved in that a kind of hydrogenation reaction kettle, comprise cylindrical shell, steam pipeline and the spherical low head of going up, described steam pipeline is fixed on around the described cylindrical shell inboard by support, described cylindrical shell two ends are fixed with low head on the described sphere, described upper cover is provided with discharging opening, described low head is provided with charging aperture, it is characterized in that: described cylindrical shell is made up of inner core and urceolus.
Described steam pipeline is a double-decker.
The utility model compared with prior art has following advantage:
1. because after the cylindrical shell of reactor adopts the blast composite methods to combine by stainless steel and carbon steel steel plate, change to be pressed into cylindrical shape and to be welded through heating, under the condition that guarantees reactor intensity, greatly reduce the manufacturing cost of reactor like this.
2. because steam pipeline is a double-decker, shorten the heat time heating time of reactor, improved the operating efficiency of reactor.
Description of drawings:
Fig. 1 is the structural representation of hydrogenation reaction kettle described in the utility model
Fig. 2 is the cross section enlarged drawing of cylindrical shell shown in Fig. 1
1. low head 2. steam pipelines 3. supports 4. cylindrical shells 5. upper covers
6. discharging opening 7. charging apertures 8. inner cores 9. urceolus
The specific embodiment:
From Fig. 1 and 2 as can be seen, a kind of hydrogenation reaction kettle, comprise cylindrical shell 4, steam pipeline 2 and the spherical low head 5 and 1 of going up, described steam pipeline 2 is fixed on around described cylindrical shell 4 inboards by support 3, described cylindrical shell 4 two ends are fixed with low head 5 and 1 on the described sphere, described upper cover 5 is provided with discharging opening 6, described low head 1 is provided with charging aperture 7, after cylindrical shell 4 adopts the blast composite methods to combine by stainless steel and carbon steel steel plate, be welded after the heating commentaries on classics is pressed into cylindrical shape, promptly cylindrical shell 4 is made up of stainless steel inner core 8 and carbon steel outer 9.
In order to shorten the heat time heating time of reactor, improved the operating efficiency of reactor, steam pipeline 2 is a double-decker.
