Description
Technical field
Directly-heated type 4A zeolite crystallization reactor relates to crystallization equipment technical field.
Background technology
The calcium exchange capacity of 4A zeolite is strong, is the soft water auxiliary agent STPP(sodium phosphate trimer that synthetic detergent easily causes eutrophication public hazards) ideal substitute, be the demineralized water auxiliary agent of production environmental protection non-phosphate detergent.Hydro-thermal complete synthesizing process produce 4A zeolite be with sodium metasilicate, aluminium hydroxide and NaOH be raw material through mixed glue reaction, and then at 95 ± 3 ℃ the process crystallization of 5-7 hour and obtain 4A zeolite.
The crystallization of prior art is to carry out in the general interlayer retort of chemical industry.Interlayer retort heat transfer area is the tank skin of retort.Tank body central authorities' material and retort span, from farthest, are conducted heat in reactor inhomogeneous, are unfavorable for the carrying out of crystallization.In crystallization process, without agitating device, it is also inhomogeneous conducting heat, and therefore reached reaction temperature near the temperature at tank skin place, and the temperature of tank central authorities does not often just reach.The growth uniformity of the unbalanced crystal grain that has influence on 4A zeolite of reaction temperature, and then have influence on the ability of demineralized water.
The mode of interlayer heat exchange can make a large amount of heat pass to the external space by the outer wall of retort, and the heat that scattered and disappeared, causes heat-energy losses.
Crystallization process, if with agitators such as vane types, because the shear action of stirring vane very easily blends the material after mixed glue, affect the growth crystallization of 4A zeolite grain, but there is no the crystallization temperature influence stirring, be swift in response near heated wall place, insufficient away from the reaction of heated wall place, cause crystallization incomplete.And the agitating device of driven by motor, because high-driving-ratio speed reducer generally adopts planet-cycloid reducer, that reducer structure complexity, the accuracy of manufacture require is high, cost is high, maintenance difficulty is large, very high to the technical merit requirement of service worker, general this kind of reductor is all to change while having fault, cause maintenance and repair cost high, power consumption is also large.
Summary of the invention
The a series of defects that exist in order to overcome above-mentioned prior art, the application's object is to provide one can make 4A zeolite crystallization heat utilization rate high, conducts heat by centre to even transferring heat at the bottom of surrounding and tank.Directly-heated type 4A zeolite crystallization reactor, and without heat transfer dead angle, simple in structure, power consumption is low, be easy to install, directly-heated type 4A zeolite crystallization reactor with low cost.For achieving the above object, the application adopts following technical scheme:
Directly-heated type 4A zeolite crystallization reactor, comprise discharge nozzle 1, heating micropore 2, heater 3, crystallization still main body 4, crystallization still end socket 5, charging aperture 6, charging aperture end socket 7, passage 8, heat-insulation layer 9, the reactor cone end 10, heating tube 11, it is characterized in that: the 4 bottom coupled reaction still cone ends 10 of crystallization still main body, crystallization still main body 4 tops connect crystallization still end socket 5;
Reactor cone bottom, the ends 10 connects discharge nozzle 1;
On crystallization still end socket 5, charging aperture 6 is housed, charging aperture 6 connects charging aperture end socket 7.
Described directly-heated type 4A zeolite crystallization reactor, is characterized in that: heater 3 is positioned at reactor cone central discharge nozzle 1 top, the end 10.
Described directly-heated type 4A zeolite crystallization reactor, is characterized in that: on crystallization still end socket 5, passage 8 is housed.
Described directly-heated type 4A zeolite crystallization reactor, is characterized in that: crystallization still main body 4 and the reactor cone ends 10 outer wall are equipped with heat-insulation layer 9.
Described directly-heated type 4A zeolite crystallization reactor, is characterized in that: described charging aperture 6 diameters are 250-300mm.
Described directly-heated type 4A zeolite crystallization reactor, is characterized in that: heating micropore 2 apertures are 1-2mm.
Described directly-heated type 4A zeolite crystallization reactor, is characterized in that: discharge nozzle caliber is 100～150mm.
Beneficial effect
1, directly-heated type 4A zeolite crystallization reactor, owing to adopting directly-heated, is also direct mode of heating, and thermal loss is little, saves the energy;
2, on the outer wall of the heater 3 of directly-heated type 4A zeolite crystallization reactor, have heating micropore 2, the thermal shedding in heating micropore is enough to play stirring action to the material in reactor, and don't can, by the material cutting after mixed glue as agitator arm, affect crystallization;
3, the bubble being bloated by heating micropore 2, because heater 3 tops are cylindrical, bottom is conical, bubble enters after crystallizing kettle, the heating bubble transverse movement on columniform top, bottom is that conical heating bubble is towards the motion of oblique below, through directly-heated type 4A zeolite crystallization reactor bottom, because being subject to the buoyancy of reaction system liquid phase material and the effect of material resistance, risen gradually by directly-heated type 4A zeolite crystallization reactor bottom again, do not stay heating dead angle, in whole reactor, thermograde is very little, and reaction evenly;
Heating is heated bubble simultaneously reaction system is carried out to micro-stirring, saves the power that power stirs.
Directly-heated type 4A zeolite crystallization reactor is simple in structure, with low cost.
