Description
Technical field
Direet-heating 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(tripoly phosphate sodium STPP that synthetic detergent easily causes eutrophication public hazards) ideal substitute, be the softening water auxiliary agent of production environmental protection free phosphate detergent.Hydro-thermal complete synthesizing process produce 4A zeolite be with water glass, aluminium hydroxide and sodium hydroxide 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 whipping appts, it is also inhomogeneous conducting heat, and therefore the temperature near tank skin place has reached temperature of reaction, and the temperature of tank central authorities does not often just reach.The unbalanced growth uniformity coefficient that has influence on the crystal grain of 4A zeolite of temperature of reaction, and then have influence on the ability of softening 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 shearing action of agitating 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, near heated wall place, be swift in response, insufficient away from the reaction of heated wall place, cause crystallization incomplete.And the whipping appts of driven by motor, because high-driving-ratio speed reducer generally adopts planet-cycloid reducer, reducer structure is complicated, manufacturing accuracy requirement is high, cost is high, maintenance difficulty is large, to the state of the art of service worker, require very high, general this kind of step-down gear 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 a kind of 4A zeolite crystallization heat utilization rate that can make high, conducts heat by centre to even transferring heat at the bottom of surrounding and tank.Direet-heating type 4A zeolite crystallization reactor, and without heat transfer dead angle, simple in structure, power consumption is low, be easy to install, direet-heating type 4A zeolite crystallization reactor with low cost.For achieving the above object, the application adopts following technical scheme:

Beneficial effect
1, direet-heating type 4A zeolite crystallization reactor, owing to adopting directly-heated, is also direct heating mode, and calorific loss is little, save energy;
2, on the outer wall of the well heater 3 of direet-heating 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 paddle wheel, affect crystallization;
3, the bubble being bloated by heating micropore 2, because well 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 direet-heating type 4A zeolite crystallization reactor bottom, because being subject to the buoyancy of reaction system liquid phase material and the effect of material resistance, by direet-heating type 4A zeolite crystallization reactor bottom, risen gradually 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.
Direet-heating type 4A zeolite crystallization reactor is simple in structure, with low cost.
