Abstract
The utility model provides a bromobenzene reaction unit, includes compounding cauldron, reaction tower, receipt jar, compounding cauldron and reaction tower bottom connect, the reaction tower jar connect with receiving, the reaction tower inside be equipped with the filler that intercrossing formed, the filler by one -tenth made of iron, compounding cauldron and reaction tower between be equipped with the charge pump, the below of compounding cauldron be equipped with the ball valve. The utility model discloses a bromobenzene reaction unit comprises compounding cauldron, reaction tower, receipt jar, through mixing the earlier stage of compounding cauldron, during the reaction tower is sent into to the reaction material of rethread charging pump in with the compounding cauldron, the transport through the charging pump need not the people the transport, empty. Being equipped with the filler made of iron of cross arrangement in the reaction tower, utilizing filler made of iron as the catalyst, circulated use catalyst improves the utilization ratio of catalyst, reduce solid useless, improve the productivity. The material is thrown in the manual work of production process out of use, directly can use the pipe -line transportation, reduces work load and process loss.
Description
Technical field
The utility model relates to a kind of bromobenzene reaction unit.
Background technology
At present, the preparation method of bromobenzene is: first add in reactor by iron powder and benzene, opens under stirring normal temperature and slowly adds bromine, in 70-80 DEG C of insulation reaction 1h after dropping terminates, gained crude product water and the washing of 5% sodium hydroxide solution, stratification, then carries out water distillation.By be separated after aqueous phase do wastewater treatment, oil phase after rectification process bromobenzene, benzene finished product.Therefrom known, the equipment preparing bromobenzene is very simple, only needs reactor.As above the structure device of preparing bromobenzene is complicated for mode of operation operating personnel, workload is large, and whole mode of operation production capacity is low, and the utilization ratio of catalyzer is low.
Summary of the invention
For above-mentioned the deficiencies in the prior art part, the problem that the utility model solves is: traditional mode of operation is locked, production capacity is low, catalyst utilization is low.
For solving the problem, the technical scheme that the utility model is taked is as follows:
A kind of bromobenzene reaction unit, comprises mixing kettle, reaction tower, receiving tank; Described mixing kettle is connected with bottom reaction tower; Described reaction tower is connected with receiving tank; Described reaction tower inside is provided with the filler mutually intersected; Described filler is fabricated from iron; Fresh feed pump is provided with between described mixing kettle and reaction tower; The below of described mixing kettle is provided with ball valve.
Further, tail gas absorption still, condenser is also comprised; Described tail gas absorption still is connected with the upper end of reaction tower; Condenser is provided with between described reaction tower and tail gas absorption still.
Further, also test tank is comprised; Described test tank is located at above mixing kettle.
The beneficial effects of the utility model
1. a kind of bromobenzene reaction unit of the present utility model, be made up of mixing kettle, reaction tower, receiving tank, mixed by the early stage of mixing kettle, then by take away pump, the reaction material in mixing kettle sent in reaction tower, by the conveying of take away pump without the need to people carrying, topple over.Be provided with iron filler arranged in a crossed manner in reaction tower, utilize iron filler as catalyzer, can be recycled catalyzer, improves the utilization ratio of catalyzer, reduces solid waste, improves production capacity.Production process no longer uses Manual material feeding, directly can use Cemented filling, reduces workload and process loss.
2. the utility model is also set up and is comprised tail gas absorption still, condenser, and tail gas absorption still is connected with the upper end of reaction tower, arranges condenser between reaction tower and tail gas absorption still.The waste gas that the setting of structure like this can make reaction produce reclaims, and condenser can carry out condensing reflux to high-temperature gas and fully react.
3. the utility model also sets up test tank, is located at above mixing kettle by test tank.Control pan feeding proportioning qualitatively by test tank, reach accurate control, very convenient.
