Abstract
The invention provides the logical reaction unit of a kind of chlorination, it is characterized in that: at the logical chlorine pipeline (4) of the bottom of reactor (1) access, one end of logical chlorine pipeline (4) is connected with ring-type chlorine tube (3), ring-type chlorine tube (3) is provided with one group of shower nozzle (6) upwards, be provided with one to drip with furfuryl alcohol solution and manage ring-type that (5) be connected at the top place of being spaced a distance of ring-type chlorine tube (3) and drip and manage (2), drip in ring-type and pipe (2) is provided with one group of downward shower nozzle (6a).The invention has the advantages that, structure is simple, transformation is convenient, while raising production capacity, reduce again the impact of excessive chlorine on environment.
Description
Technical field:
The present invention relates to a kind of chlorination reaction device, the chlorination particularly in a kind of acesulfame potassium production is logical drips a reaction unit.
Background technology:
Chlorination reaction in acesulfame potassium production is mainly divided into following step: 1, the methanol aqueous solution of methyl alcohol dosage bunker configuration content 54% ~ 56%, with circulating pump, the methanol solution configured is squeezed into chlorination tank and the cooling of open cycle pump.2, configure the mixed liquor of furfuryl alcohol and methyl alcohol, furfuryl alcohol (kg) and methyl alcohol (L) ratio are 1:1 simultaneously.3, when chlorination tank temperature drop is to-16 DEG C, can starting to drip furfuryl alcohol solution, by the chlorination tube line on chlorination tank top, chlorine be passed into chlorination tank simultaneously, dripping than being 24L:12kg by logical.4, after chlorination reaction terminates, send into hydrolysis distillation still with circulating pump, open steam and carry out adding thermal distillation, and constant temperature hydrolysis.Methyl alcohol enters condenser and enters buffering knockout drum from top, gas phase is chloromethanes, and enter chloromethanes recycle section, Liquid Phase Methanol enters accumulator tank.
And this traditional chlorinated reaction, logical chlorine and dropping furfuryl alcohol could be reacted when concentration reaches a timing and react insufficient.In order to ensure that furfuryl alcohol can have been reacted, chlorine must be excessive, causes so such as: production efficiency is low, power consumption increases, too much chlorine is to shortcomings such as the pollutions of environment.
The content of invention:
The present invention is exactly to solve deficiency of the prior art, provides a kind of low energy consumption, high production and the chlorination of environmental protection are more logical drips a reaction unit.
To achieve these goals, the invention provides following technological means:
A kind of chlorination is logical drips reaction unit, it comprises: reactor, it is characterized in that: at the logical chlorine pipeline of the bottom of reactor access, one end of logical chlorine pipeline is connected with ring-type chlorine tube, ring-type chlorine tube is provided with one group of shower nozzle upwards, above ring-type chlorine tube, place is spaced a distance and is provided with one and drips with furfuryl alcohol solution and manage the ring-type be connected and drip and manage, and drips pipe is provided with one group of downward shower nozzle in ring-type.
On the basis of technique scheme, following further technical scheme can also be had:
Arrange in reactor one group of titanium alloy fixed bar ring-type chlorine tube and ring-type are dripped manage fixing.
The invention has the advantages that:
Structure of the present invention is simple, transformation is convenient, while raising production capacity, reduce again the impact of excessive chlorine on environment.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention:
As shown in Figure 1, a kind of chlorination is logical drips reaction unit, at the logical chlorine pipeline 4 of the bottom of reactor 1 access, one end of logical chlorine pipeline 4 is connected with ring-type chlorine tube 3, ring-type chlorine tube 3 is provided with one group of shower nozzle 6 upwards, above ring-type chlorine tube 3 interval about 30cm position on, arrange one and drip with furfuryl alcohol solution the ring-type that pipe 5 is connected and drip pipe 2, drip in ring-type and pipe 2 is provided with one group of downward shower nozzle 6a.
In reactor 1, arrange one group of titanium alloy fixed bar 7 chlorine gas distributor 3 and dropping distributor 2 are fixed.
Be provided with conduit 8 in the bottom of reactor 1, conduit 8 connect successively drip pipeline 9, circulating pump 10, plate type heat exchanger 11 drip pipe 5 with furfuryl alcohol solution again and be connected.
Thus form a circulatory system, achieve the object improving production capacity and reduce the consumption of chlorine and the pollution to environment.
