Abstract
The utility model discloses a reaction kettle, comprising a metal shell and a sealing cap. The metal shell is arranged on a base and the sealing cap covers the metal shell and is sealed and locked through a flange structure. A thermometer sleeve and a feed inlet are arranged on the sealing cap and an agitator blade is arranged on the sealing cap. A heat conductive inlet and a heat conductive outlet are arranged on the side surface of the metal shell. The heat conductive outlet is higher than the heat conductive inlet. A discharge hole is arranged on the bottom surface of the metal shell. A clamp and a metal lining are arranged orderly in an inner cavity of the metal shell. The metal lining is formed by integral metal lantern rings which are vertically overlapped, sealed and bonded. The overlapping height between the metal lantern rings is smaller than half of the height of the metal lantern rings. The reaction kettle provided by the utility model adopts an integral ring-like structure and is dipped by polytetrafluoroethylene so that the metal is not easy to fall off in the condition of high temperature corrosion of a mixed solution of phosphoric acid and hydrochloric acid and the heat conductive medium heats the metal directly to transfer heat to the reaction feed liquid with good heat conductivity.
Description
Technical field
The utility model relates to a kind of under the high temperature corrosion condition of phosphoric acid and hydrochloric acid mixed solution, and the direct heating of metal of heat-conducting medium passes to heat the agitated reactor that reacts feed liquid.
Background technology
In the existing various agitated reactor; The underneath side of a quilt of metal is all through binding agent and steel material bonding; Because the difference of the coefficient of expansion between common clad lining and the steel material of the underneath side of a quilt and the binding agent, under the high temperature corrosion condition of phosphoric acid and hydrochloric acid mixed solution, metal comes off easily; And conduct heat to metal through steel material, its heat transfer property is poor.
The utility model content
Goal of the invention: in order to overcome the deficiency that exists in the prior art, it is a kind of under the high temperature corrosion condition of phosphoric acid and hydrochloric acid mixed solution that the utility model provides, the agitated reactor of metal difficult drop-off, good heat-transfer.
Technical scheme: for solving the problems of the technologies described above, the technical scheme of the utility model sampling is:
A kind of agitated reactor comprises metal shell and capping, and metal shell is arranged on the base, and capping is covered on metal shell, and through flange arrangement sealing locking; In capping, be provided with thermometer boss and charging aperture, and paddle is installed; Be provided with the outlet of heat-conducting medium import and heat-conducting medium in the side of metal shell, the heat-conducting medium exit position is higher than the heat-conducting medium entrance location, is provided with drain hole in the bottom surface of metal shell, is provided with chuck and clad lining successively at the inner chamber of metal shell; Said clad lining is formed by the vertical lap seal bonding of the integrally-built metal collar, and the metallic sheath ring set that is positioned at upside is contained in the outside of the metal collar that is positioned at downside, and the overlapping height of metallic sheath interannular is half the less than metal collar height.
The metal collar adopts the metal material through the polytetrafluoroethylene (PTFE) dipping, and the plasticization temperature of its dipping is 350 ℃ to 430 ℃, preferred 385 ℃; In this agitated reactor, its capping, charging aperture, drain hole, thermometer boss adopt integrally-built material to process, and adopt integrally-built metal material to process such as capping.
Chuck is through heat-conducting oil heating in this agitated reactor, and heating-up temperature is 220 ℃ to 280 ℃, and preferred heating-up temperature is 250 ℃, and pressure is less than or equal to 0.6Mpa.
The operating temperature of this agitated reactor is more than 220 ℃, and working media is mixtures such as phosphoric acid (concentration is more than 85%) and small amount of hydrochloric acid.
Beneficial effect: the agitated reactor that the utility model provides adopts whole loop configuration, and through the polytetrafluoroethylene (PTFE) dipping, under the high temperature corrosion condition of phosphoric acid and hydrochloric acid mixed solution; The metal difficult drop-off; And the direct heating of metal of heat-conducting medium passes to reaction feed liquid, good heat-transfer with heat.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
Be depicted as a kind of agitated reactor like accompanying drawing 1, comprise metal shell 1 and capping 7, metal shell 1 is arranged on the base 2, and capping 7 is covered on metal shell 1, and through flange arrangement sealing locking; In capping 7, be provided with thermometer boss 5 and charging aperture 8, and paddle 4 is installed; Be provided with heat-conducting medium import 9 and heat-conducting medium outlet 10 in the side of metal shell 1; Heat-conducting medium exports 10 positions and is higher than heat-conducting medium import 9 positions; Be provided with drain hole 11 in the bottom surface of metal shell 1, be provided with chuck 6 and clad lining 3 successively at the inner chamber of metal shell 1; Said clad lining 3 is formed by the vertical lap seal bonding of the integrally-built metal collar, and the metallic sheath ring set that is positioned at upside is contained in the outside of the metal collar that is positioned at downside, and the overlapping height of metallic sheath interannular is half the less than metal collar height.
The metal collar adopts the metal material through the polytetrafluoroethylene (PTFE) dipping, and the plasticization temperature of its dipping is 350 ℃ to 430 ℃, preferred 385 ℃; In this agitated reactor, its capping, charging aperture, drain hole, thermometer boss adopt integrally-built material to process.
The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
