Abstract
The utility model provides a synthetic reation kettle that uses of sulfamic acid, includes the cauldron body and installs at these internal stirring parts of cauldron that the cauldron body is made by the stainless steel, is equipped with the circulating water cooling and presss from both sides the cover outside the cauldron body, at this internal steam temperature rising coiled pipe that is equipped with of cauldron. This reation kettle has that reaction effect is good, low in production cost, the reaction rate is fast, production efficiency is high advantage.
Description
Technical field
The utility model relates to Description on Production of Sulfaminic Acid technical field, especially relates to a kind of sulfamic acid synthesis reactor.
Background technology
Sulfamic acid is important fine chemical product, of many uses.Sulfamic acid synthetic method is numerous, wherein oleum method be with oleum and urea for raw material, excessive oleum is added in reactor, stirs and be cooled to 20 DEG C-40 DEG C, start to add the sulfuric acid and urea that mix in proportion, after reinforced end, stir 8 hours, then be warming up to 70 DEG C-90 DEG C gradually, cooling crystallization, obtain thick sulfamic acid after Separation of Solid and Liquid, with water recrystallization, dehydrate to obtain high-purity fine work sulfamic acid.
In above-mentioned course of reaction, due to the severe corrosive of sulfuric acid, the reaction vessel of use is generally corrosion resistant enamel still; Because above-mentioned course of reaction first lowers the temperature to heat up again, therefore need two reactor series connection, first reactor peripheral hardware cyclic water jacket is lowered the temperature, after a reaction completes, two reactions will be carried out in mass transport to the second reactor, utilize steam to heat up to reactor, obtain the thick liquid of sulfamic acid.Such as application number is in the application for a patent for invention of 201410118544.8, namely discloses a whole set of production line adopting above-mentioned two legal system sulfamic acids, and wherein a reaction is carried out in absorption kettle 1, and two reactions are carried out in synthesis reaction vessel 2.
Although two legal system sulfamic acids are widely used in chemical industry, there are two large defects in it: 1) although enamel still is corrosion-resistant, good heat preservation performance, and the circulating water chuck cooling reaction time used is long, and enamel still acquisition cost is high; 2) material is carried in the second reactor from the first reactor, not only heat-energy losses, and more importantly, mass transport causes the prolongation of production time, increases product cost.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming existed in prior art, a kind of sulfamic acid synthesis reactor is provided, this reactor is made up of special stainless steel, there is the characteristic of sulfuric acid corrosion resistant, simultaneous reactions still peripheral hardware circulating water cooling chuck, inside establish intensification coil pipe, two reactions of sulfamic acid can be completed in a reactor, the technical scheme adopted is: a kind of production sulfamic acid reactor, comprise still body and be arranged on the intrinsic mixing component of described still, it is characterized in that: described still body is made up of stainless steel, circulating water cooling chuck is provided with outside described still body, steam intensification coil pipe is provided with in described still body.
Technical characteristic of the present utility model also has: described stainless steel is 316L stainless steel.
Technical characteristic of the present utility model also has: described mixing component comprises shaft, stretches in the intrinsic part of described still paddle is housed at described shaft.
The beneficial effects of the utility model are: this sulfamic acid overcomes with reactor the metal kettle always existed in prior art cannot be used for the technology prejudice that sulfuric acid holds, the reactor changing material not only reduces acquisition cost, and has good reaction speed; Integrate circulating water cooling and steam pipe coil intensification function, use this reactor synthesizing amino sulfonic acid, only need a reaction to complete, not only avoid the heat-energy losses that in two reactions, Flow of Goods and Materials causes, and save the flowing time of material between two stills; This reactor has the advantage that reaction effect is good, production cost is low, reaction speed is fast, production efficiency is high.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation, and wherein, 1 is still body, and 2 is shafts, and 3 is paddles, and 4 is circulating water cooling chucks, and 5 is steam intensification coil pipes.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.The utility model discloses a kind of sulfamic acid synthesis reactor, the mixing component that this reactor comprises still body 1 and is arranged in still body 1, mixing component comprises shaft 2, stretch at shaft 2 in the part in still body 1 and paddle 3 is housed, shaft 2 rotates under stirring motor (not shown) drives, drive paddle 3 mounted thereto to rotate, complete being uniformly mixed of material.Still body 1 is made up of stainless steel, is provided with circulating water cooling chuck 4 outside still body 1, is provided with steam intensification coil pipe 5 in still body 1.
Find in practice, as the sulfuric acid of one of reaction material, after sulfuric acid concentration is lower than 92.5%, strong to corrosion of metal, and when the concentration of sulfuric acid is more than 92.5%, along with the increase of sulfuric acid concentration, it declines on the contrary to metal protection, and due to the stainless corrosion resistance of 316L better, under the prerequisite ensureing sulfuric acid concentration, the reactor be made up of 316L stainless steel can meet the needs of sulfamic acid synthesis.Therefore, this is novel have employed reactor of sulfamic acid synthesis that stainless steel selected especially makes, to reduce equipment cost, and increases reaction speed, and can exterior circulating water cooling chuck 4 simultaneously, in-built steam intensification coil pipe 5.
Certainly; above-mentioned explanation is not limitation of the utility model; the utility model is also not limited only to above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also belongs to protection domain of the present utility model.
Claims (3)
