Abstract
The utility model discloses a device which utilizes steam to replace hydrogen, and belongs to the field of xylitol or maltitol processing. The device comprises a reaction kettle, and a hydrogen inlet pipe, a material inlet pipe, a hydrogen exhaust pipe and a material outlet pipe which are respectively communicated with the top of the reaction kettle, wherein, the hydrogen inlet pipe extends into the bottom of an inner cavity of the reaction kettle; a steam inlet pipe is arranged on the upper part of the reaction kettle, and a condensing water exhaust pipe is arranged on the lower part of the reaction kettle. Compared with the prior art, the device which utilizes steam to replace hydrogen has the advantages of convenient operation, thorough replacement, cost reduction and no waste. As the steam has certain pressure (about 6kg), the steam is converted into water when cooled, and does not carry oxidizing substances of oxygen and the like, which can avoid bringing bad effect on materials and catalysts by oxygen and the like when the device is utilized again.
Description
Technical field
The utility model relates to a kind of maintenance process device in xylitol or the maltitol hydrogenation operation, specifically a kind of device that utilizes steam displacement hydrogen.
Background technology
Wood sugar is in hydrogenation process, because equipment needed thereby is the high pressure tankage, in process of production, equipment, valve pipe etc. are fragile, need to change or maintenance, go out equipment and ducted hydrogen exchange, what generally adopt at present is that ducted hydrogen adopts water to replace the hydrogen nitrogen replacement in the equipment.There is following shortcoming in the method: 1), ducted hydrogen in the process that water replaces, replace not thoroughly (pressure of pump is about 3kg), in maintenance process, have potential safety hazard; 2), water consumption is bigger, should not reclaim; 3), the hydrogen nitrogen replacement in the equipment container, expense is than higher.
Summary of the invention
Technical assignment of the present utility model is at above weak point, and a kind of rational in infrastructure, maintenance cost is low, easy to operate a kind of device that utilizes steam displacement hydrogen is provided.
The technical scheme that its technical problem that solves the utility model adopts is: this device comprises reactor, hydrogen air inlet pipe, feed pipe, hydrogen blast pipe and discharge nozzle, hydrogen air inlet pipe, feed pipe, hydrogen blast pipe and discharge nozzle are connected with the top of reactor respectively, wherein the hydrogen air inlet pipe is goed deep into the bottom of reactor inner chamber, the top of reactor is provided with the steam steam inlet pipe, and the bottom of reactor is provided with condensed water discharge pipe.
Be provided with steam valve between described steam steam inlet pipe and the hydrogen air inlet pipe, hydrogen air inlet pipe, hydrogen blast pipe and discharge nozzle and reactor connection place are provided with steam valve.
A kind of device of steam displacement hydrogen that utilizes of the present utility model is compared with prior art, have following characteristics: easy to operate, replace thoroughly, and reduction expense, do not have waste,, when cooling, be converted into water because steam has certain pressure (about 6kg), do not bring oxidizing substances such as equipment oxygen into, when equipment utilizes again, can avoid the adverse effect to material and catalyst such as oxygen.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is a kind of structural representation that utilizes the device of steam displacement hydrogen.
Among the figure: 1, reactor, 2, steam valve, 3, the steam steam inlet pipe, 4, the hydrogen air inlet pipe, 5, feed pipe, 6, the hydrogen blast pipe, 7, discharge nozzle, 8, condensed water discharge pipe.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
A kind of device that utilizes steam displacement hydrogen of the present utility model, its structure comprises reactor 1, hydrogen air inlet pipe 4, feed pipe 5, hydrogen blast pipe 6 and discharge nozzle 7, hydrogen air inlet pipe 4, feed pipe 5, hydrogen blast pipe 6 and discharge nozzle 7 are connected with the top of reactor 1 respectively, wherein hydrogen air inlet pipe 4 is goed deep into the bottom of reactor 1 inner chamber, the top of reactor 1 is provided with steam steam inlet pipe 3, and the bottom of reactor 1 is provided with condensed water discharge pipe 8.
Be provided with steam valve 2 between steam steam inlet pipe 3 and the hydrogen air inlet pipe 4, hydrogen air inlet pipe 4, hydrogen blast pipe 6 and discharge nozzle 7 are provided with steam valve 2 with reactor 1 connection place.
In the time of need replacing displacement, Open valve gets final product.Because steam has uniform temperature, when replacing pipeline, to pay special attention to, avoid scalding.
A kind of its processing and fabricating of device of steam displacement hydrogen that utilizes of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
