Abstract
A cracking kettle, comprising a kettle main body, an upper shell cover, a lower shell cover, an agitator, a materiel inlet arranged on the cracking kettle, a gas phase outlet, a liquid phase outlet, a temperature-measuring porthole, a pressure-measuring porthole, a sight glass, and an emptying porthole. The utility model is characterized in that a baffle is arranged inside the kettle body, and a jacket for providing thermal to the cracking kettle is arranged outside the kettle body, to enlarge the dimension of the cracking kettle and the proportion between the height and the diameter of the cracking kettle.
Description
One, technical field
The utility model relates to the cracker cracking still in the hydrolysate cracking process in a kind of organosilicon industry, belongs to technical field of chemical.
Two, background technology
At present, the less or slowly enlarging of most organosilicon producer production capacity, but be used for the cracking still of water-splitting unit, volume is less, generally all less than 6m
3, expand production and use all generally that the small-sized cracking still of 2-3 is in parallel to be produced, not only increase the investments such as use place, process pipelines, technology controlling and process of equipment, and brought bigger difficulty also for the management of equipment, operation.
Cracking reaction is an endothermic process, need satisfy the needed heat of reaction with outside heat supply.In existing the production, some producers still use the cracking still of not being with stirring, and the shortcoming of this cracking still is that material absorption heat is inhomogeneous; Most of producer has adopted the form that stirs to make mixing of materials even, can absorb heat uniformly, reacts more abundant.
Be 03200683.7 in the patent No., name is called in the patent of " cracker ", disclose in cracking still inside and set up the technical scheme that coil pipe is strengthened heat supply.The advantage of this innovative point is the heat transfer efficiency that has improved cracking still, but there are many drawbacks in it: 1, at the inner coil pipe that increases of still, reduced the usage space in the still, the relative output that reduced; 2, equipment is after long running, and binding material easily on the coil pipe wall had both influenced the heating efficiency of coil pipe, made equipment need often cleaning again, influenced ordinary production; 3, because the still internal reaction is under vacuum state, and steam pressure is too high in the coil pipe, and coil pipe pad etc. are revealed directly influence and produced; 4, because the existence of inner coil pipe, and removed baffle plate, made that the mixing of materials uniformity coefficient is not enough.
Three, summary of the invention
The purpose of this utility model is, overcomes the defective of prior art, provides a kind of and can satisfy large-scale production, sufficient reacting, stable, and installation, management, operation, cracking still easy to maintenance.
A kind of cracking still, comprise still main body, upper cover, low head, agitator, be distributed in material inlet, gaseous phase outlet, liquid phase outlet, temperature-measuring port, pressure tap, visor, drain on the cracking still, it is characterized in that baffle plate being set in kettle inside, in the kettle outer setting is the chuck of cracking still heat supply, increases the ratio of volume and the cracking still height and the diameter of cracking still.
Described baffle plate is provided with the 2-4 sheet.
Described chuck is S type half-pipe jacket or band spiral guide plate type chuck.
The high ratio with diameter of described cracking still is 3: 1-0.8: 1.
The course of work of the present utility model is: from the hydrolysate of hydrolysis unit through after the preheating with after catalyst from the catalyst jar mixes in strict ratio, the material inlet on kettle enters cracking still.Material fully mixes and carries out the cracking rearrangement under the effect of stirring and baffle plate, obtains mixed methylcyclosiloxane.Gas-phase product enters cleavage column through gaseous phase outlet and carries out rectifying.The silanol first salt that reaction generates and a small amount of unreacted hydrolysate, catalyst are discharged by the liquid phase mouth.Reacting needed heat is evenly supplied with by outside half-pipe jacket.Temperature in the kettle and pressure detect control by thermo detector, manometer, and control the flow and the temperature of conduction oil with the thermo detector signal, so that more stable control reaction temperature.
The utility model has the advantages that:
1, increased baffle plate, it is more even that material is mixed under the effect of stirring and baffle plate, reacts more abundant.
2, adopt the chuck of S type half-pipe jacket or band spiral guide plate type, guaranteed the heat exchange area of still; And carry out temperature control by conduction oil.Because the conduction oil temperature is convenient to regulate, make reaction temperature adjustableization that also become, react more abundant.
3, increased the volume of still, reasonably the ratio of cracking still height and diameter making the production of maximizing become feasible.Through the data of strict calculating, conditioned reaction rotating speed and baffle plate, and the regulation and control of temperature, the output of single still and the quality of product all are significantly improved.
The utlity model has and to satisfy large-scale production, sufficient reacting, stable, and installation, management, operation, characteristics easy to maintenance.

Wherein, 1, the still main body, 2, upper cover, 3, low head, 4, agitator, 5, baffle plate, 6, chuck, 7, material inlet, 8, gaseous phase outlet, 9, the liquid phase outlet, 10, temperature-measuring port, 11, pressure tap, 12, visor, 13, drain.
Five, the specific embodiment
Embodiment 1: structure of the present utility model as shown in Figure 1, comprise still main body, upper cover, low head, agitator, be distributed in material inlet, gaseous phase outlet, liquid phase outlet, temperature-measuring port, pressure tap, visor, drain on the cracking still, it is characterized in that baffle plate being set in kettle inside, in the kettle outer setting is the chuck of cracking still heat supply, increases the ratio of volume and the cracking still height and the diameter of cracking still.
Described baffle plate is provided with 2.
Described chuck is a S type half-pipe jacket.
The high ratio with diameter of described cracking still is 3: 1.
Embodiment 2: structure of the present utility model is identical with embodiment 1, and difference is that described baffle plate is provided with 3, and described chuck is band spiral guide plate type chuck, and the high ratio with diameter of described cracking still is 1.5: 1.
