Description
Technical field:
The present invention relates to a kind of chlorination reaction device, particularly the logical reaction unit that drips of chlorination in a kind of acesulfame potassium production.
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 configuring is squeezed into chlorination tank 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 ℃ time, can start to drip furfuryl alcohol solution, the chlorination tube line by chlorination tank top passes into chlorination tank by chlorine simultaneously, by logical, drips than being 24L:12kg.4, after chlorination reaction finishes, with circulating pump, send into hydrolysis distillation still, open steam and add thermal distillation, and constant temperature hydrolysis.Methyl alcohol enters condenser and enters buffering knockout drum from top, gas phase is chloromethanes, enters chloromethanes recycle section, and Liquid Phase Methanol enters accumulator tank.
And this traditional chlorination reaction, logical chlorine and dropping furfuryl alcohol regularly could react and react insufficient when concentration reaches one.In order to guarantee that furfuryl alcohol can react, chlorine must be excessive, caused like this such as: production efficiency is low, power consumption increases, the too much chlorine shortcomings such as pollution to environment.
The content of invention:
The present invention is exactly in order to solve deficiency of the prior art, and the logical reaction unit that drips of chlorination of a kind of low energy consumption, high production and environmental protection is more provided.
To achieve these goals, the invention provides following technological means:
The logical reaction unit that drips of a kind of chlorination, 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, on ring-type chlorine tube, be provided with one group of shower nozzle making progress, above ring-type chlorine tube, locating to be spaced a distance is provided with a ring-type dropping pipe being connected with furfuryl alcohol solution dropping pipe, in ring-type, drips on pipe and is provided with one group of downward shower nozzle.
On the basis of technique scheme, can also there is following further technical scheme:
One group of titanium alloy fixed bar is set in reactor ring-type chlorine tube and ring-type dropping pipe is fixing.
The invention has the advantages that:
The present invention is simple in structure, transformation is convenient, when improving production capacity, reduces again the impact of excessive chlorine on environment.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
The specific embodiment:
As shown in Figure 1, the logical reaction unit that drips of a kind of chlorination, 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, on ring-type chlorine tube 3, be provided with one group of shower nozzle making progress 6, on the position of 30cm left and right in interval above ring-type chlorine tube 3, arrange one and drip with furfuryl alcohol solution the ring-type dropping pipe 2 that pipe 5 is connected, in ring-type, drip on pipe 2 and be provided with one group of downward shower nozzle 6a.
At reactor 1, interior that one group of titanium alloy fixed bar 7 is set is fixing with dropping distributor 2 by chlorine gas distributor 3.
In the bottom of reactor 1, be provided with conduit 8, conduit 8 connects successively dropping pipeline 9, circulating pump 10, plate type heat exchanger 11 and is connected with furfuryl alcohol solution dropping pipe 5.
Thereby form a circulatory system, realized the consumption and the object to the pollution of environment that improve production capacity and reduce chlorine.
