Abstract
The invention relates to an acesulfame production continuous proportioning method and an apparatus for achieving the method. A mass flow meter is mainly used for controlling the flow rate of materials sulfur trioxide and dichloromethane, so that the materials can be delivered to a static mixer for mixing and proportioning. The acesulfame production continuous proportioning method and the apparatus for achieving the method has the advantages of achieving the continuity of production operations, shortening the preparation time, reducing side reaction, improving the yield of sulfonation reaction, improving the product quality and yield due to the high material ratio balance stability, reducing the labor intensity of workers, and greatly improving the production efficiency.
Description
Technical field
The present invention relates to acesulfame potassium production field, particularly sulfur trioxide and carrene compound method and the device in a kind of acesulfame potassium sulfonation workshop section.
Background technology
As shown in Figure 1, the mixing of sulfur trioxide and carrene, carries out the preparation process of the sulfonating agent sulfur trioxide in traditional acesulfame potassium sulfonation workshop section in preparing tank, and then circulates and make to mix fully with circulating pump.Sulfur trioxide and the carrene octarius scale of all using tricks in preparing tank weighs, error in dipping is larger, and due to the finite capacity of preparing tank and circulating pump, carry out the preparation of 18 times, just can reach a required metering of sulfonating reaction, production efficiency is low, material waste is serious, because the preparation time is long, causes side reaction many, production capacity is low, and production cost is high.
Summary of the invention
Object of the present invention is exactly that a kind of acesulfame potassium sulfur trioxide providing and carrene mix new technology in order to overcome first by the shortcoming existing in technology.
The present invention is by the following technical solutions:
A continuous compounding method in acesulfame potassium production, is characterized in that comprising the following steps:
1) open the force (forcing) pump that carrene storage tank connects, make carrene flow to static mixer, by mass flowmenter control flow within the scope of 2.8 ~ 3.5 t/h;
2) open the force (forcing) pump that sulfur trioxide storage tank connects, make sulfur trioxide flow to static mixer, by mass flowmenter control flow within the scope of 1.4 ~ 2 t/h;
3) flow of control carrene and sulfur trioxide reaches the proportioning of 1.96:1, after mixing, sends into sulfur trioxide measuring tank by static mixer.
The present invention also provides a kind of device of realizing said method, it is characterized in that this device comprises:
A sulfur trioxide storage tank, a force (forcing) pump 1, described force (forcing) pump 1 one end is connected with sulfur trioxide storage tank with pipe box, and the other end is connected with a mass flowmenter 1 with pipe box, and described mass flowmenter 1 use pipe box is connected with static mixer; A carrene storage tank, a force (forcing) pump 2, described force (forcing) pump 2 one end are connected with carrene storage tank with pipe box, and the other end is connected with mass flowmenter 2 with pipe box, and the other end of described mass flowmenter 2 is connected with static mixer with pipe box.
Advantage of the present invention:
1, realize the continuity of production operation, shortened the preparation time, reduce side reaction, improve sulfonating reaction yield.
2, more original traditional preparing tank preparing process, continous batching stability is high, and material proportion equilibrium is improved the quality of products and yield.
3, more original traditional batch formula proportioning process, the method has realized automation to a certain extent, has reduced workman's labour intensity, and production efficiency increases substantially.
