Description
(1) technical field
The utility model belongs to the chemical production equipment field, particularly a kind of continuous hydrogenation production system device.
(2) background technology
In traditional hydrotreatment; Need change hydrogen into liquid phase from vapor phase, it can be on catalyst surface and the oil molecular reaction in liquid phase, through making very a large amount of hydrogen and oil circulationly realizing this point through catalyst bed; Oil and hydrogen stream are crossed catalyst bed; And absorption of hydrogen is as in the film that is distributed in the oil on the catalyzer, because the requirement of hydrogen maybe be bigger, so reactor drum is very large.
At present, domestic hydrogenation method all is to adopt the intermittent type hydrogenation, and the interrupter method equipment capacity is low, and operation labour intensity is big, need carry out hydrogen exchange to reaction kettle in the production process, and hydrogen consumption is high, poor stability.
(3) summary of the invention
The utility model provides a kind of continuous hydrogenation production system device simple in structure, easy to use in order to remedy the deficiency of prior art.
The utility model is realized through following technical scheme:
A kind of continuous hydrogenation production system device; Comprise the batching still that feed-pipe is set; It is characterized in that: the material outlet of said batching still bottom connects tubular reactor through product pump, and the material outlet of tubular reactor is communicated with separator, and separator is communicated with the hydrogenation liquid bath.
The utility model gets into tubular reactor continuously with the hydrogen of mixed solution that configures and certain pressure and reacts; Reacted hydride is collected in the hydrogenation liquid bath through catalyst filter; Realize the continous way hydrogenation; Avoid the drawback of intermittent type hydrogenation generation in the past, improve the automatic controllability of producing.
The more excellent scheme of the utility model is:
Not thorough for preventing the tubular reactor internal reaction, said tubular reactor bottom is provided with circulation tube, and the top is provided with the hydrogen recovery pipe, is used for hydrogen recovery, saves production cost.
Said separator bottom is provided with the catalyst recovery pipe, is used for the separated and collected catalyzer, economizes on resources, and prolongs the work-ing life of equipment.
The utility model is simple in structure, and is easy to use, reasonable in design, and equipment is advanced, and the automatic control level is high, and labour intensity is low, and production efficiency is high, reduces unit cost, constant product quality.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model.
Among the figure, 1 batching still, 2 product pumps, 3 tubular reactors, 4 separators, 5 hydrogenation liquid baths, 6 circulation tubes, 7 hydrogen recovery pipes, 8 catalyst recovery pipes.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.This embodiment comprises the batching still 1 that feed-pipe is set, and the material outlet of said batching still 1 bottom connects tubular reactor 3 through product pump 2, and the material outlet of tubular reactor 3 is communicated with separator 4, and separator 4 is communicated with hydrogenation liquid bath 5; Said tubular reactor 3 bottoms are provided with circulation tube 6, and the top is provided with hydrogen recovery pipe 7; Said separator 4 bottoms are provided with catalyst recovery pipe 8.
Add quantitative solvent, nitro thing and catalyzer in batching by a certain percentage in the still 1, the mixed solution for preparing is sent into tubular reactor 3 through product pump 2, with the hydrogen of certain pressure in tubular reactor 3 reactions; Reacted mixed solution such as the defective batching still that comes back to utilize again; Reaction solution after qualified gets into separator 4, advances to separate the material that obtains and sends into hydrogenation liquid bath 5, and the catalyzer after the filtration regularly reclaims; Be convenient to save production cost, reach the purpose of continous way hydrogenation.
Claims (3)
1. continuous hydrogenation production system device; Comprise the batching still (1) that feed-pipe is set; It is characterized in that: the material outlet of said batching still (1) bottom connects tubular reactor (3) through product pump (2); The material outlet of tubular reactor (3) is communicated with separator (4), and separator (4) is communicated with hydrogenation liquid bath (5).
