Abstract
The utility model discloses a reactor for preparing formic acid, comprising a jacket type housing formed by the inner and outer housings, a transmission mechanism, a blender, liquid inlet and outlet arranged on the outer housing, material inlet and outlet arranged on the inner housing. The utility model is characterized in that the inner housing is of convolution type double tube structure; the blender comprises two core shafts symmetrically arranged on the inner axes of the two tubes, a plurality of plates with fan-shaped vertical section fixed on the core shafts, and leaf teeth fixed on the upper surface of every plate. The leaf teeth are spirally distributed in the direction of the shafts of the core shafts. The plates of the two core shafts are staggered and intersected. The two core shafts are connected with the transmission mechanism outside the tube. The reactor for preparing formic acid has the advantages that the materials can be blended uniformly; the adhering of the materials to the inside of reactor is avoided.
Description
Technical field
The utility model relates to a kind of reactor, especially relates to a kind of reactor that is used to prepare formic acid.
Background technology
The reactor of domestic traditional preparation formic acid is general common single axle rake formula reactor, jacket type structure for inside and outside housing formation, because producing the raw material sodium formate of formic acid is solid, and the viscosity of phosphoric acid or polyphosphoric acid is bigger, when mixing, it is the whirlpool shape that this single axle stirs what make that material forms in reactor, this mode causes mixing of materials inhomogeneous, and material easily sticks on shaft, mixing arm and the inner wall in course of reaction, cause utilization of materials low, the energy consumption height, and then influence product quality; Moreover this reaction is exothermic reaction, generally need import cooling medium in chuck and take away heat of reaction, but because material mixes inhomogeneously therein, cause non-uniform temperature in the reaction system, and overheated part side reaction is many, influences the yield and the quality of formic acid.
The utility model content
The purpose of this utility model be to overcome the shortcoming of above-mentioned prior art and provide a kind of can with mixing of materials evenly, the reactor of avoiding material in reactor, to adhere to.
The purpose of this utility model is achieved in that
A kind of auto purification type reactor that is used to prepare formic acid, comprise by interior, jacket type housing and transmission mechanism that shell body forms, rabbling mechanism, shell body is provided with into, liquid outlet, inner housing is provided with into, discharging opening, wherein said inner housing is to the mould assembly binocular structure, described rabbling mechanism comprises two mandrels that are installed on two cylindrical shell inner axes positions symmetrically, be fan-shaped impeller with several vertical sections that are fixed on the mandrel, and the leaf-teeth that are fixed on each impeller upper surface are formed, these leaf-teeth are along the axial direction shape distribution in the shape of a spiral of mandrel, impeller on two mandrels shifts to install and is interlaced, and two mandrels link to each other with cylindrical shell transmission mechanism outward.
Wherein, the impeller on every mandrel is arranged in a linear at axial direction, and scheme is to be fixed with two groups of impeller that are arranged in a linear at axial direction on mandrel symmetrically preferably.
Wherein, the upper surface of described fan-shaped impeller is that the inner arc surface with cylindrical shell is complementary, promptly except guarantee that sector can rotate freely in cylindrical shell, make the intermittence between the inner arc surface of the upper surface of fan-shaped impeller and cylindrical shell less again, material can not be sticked on the inner arc surface of cylindrical shell.
As further improvement of the utility model, also be provided with the gas outlet in the upper end of cylindrical shell.
Operation principle of the present utility model is as follows: material enters reactor from charging aperture, two mandrels rotate under the drive of transmission mechanism, the helicla flute inward turning that material constitutes along blade and leaf-teeth turns to and moves ahead, even if material adheres at cylinder inboard wall, when leaf-teeth rotate to this position next time, it can be wiped off, the material that adheres between the impeller is then wiped off by impeller corresponding on another root mandrel mutually, material is upgraded in rotating operation and is fully mixed, after reaction was finished, reactant was from discharge hole for discharge; Water inlet on shell and delivery port can feed condensed water cylindrical shell is cooled off.
The utility model has following advantage than prior art:
Because the utility model has designed by the twin-core axle, impeller, the double-shaft spiral structure that leaf-teeth constitute, impeller on the diaxon shifts to install in addition, interlaced during operation, because leaf-teeth and cylindrical shell gap are little, can constantly the material that adheres on the cylinder inboard wall be scraped to enter in the spiral conveying groove and fully mix, and between axle and the axle, material between impeller is wiped off to enter in the spiral conveying groove by the impeller on another root mandrel again and is fully mixed, solved the problem that material adheres to easily in original technology, simultaneously, this spiral mixing mode of movement, material is constantly rolled in running, mix more evenly, make reaction carry out smoothly, moreover, the cooling medium that feeds in chuck also can be fine, very equably the heat that material reaction produced in the cylindrical shell is taken away, the yield of formic acid is improved.
