Abstract
The utility model relates to a melamine production device, in particular to a melamine crude-product solubilization device, comprising a casing, a feed-liquid inlet on the casing, a slag discharge port, a clear-liquid outlet and a vent value, which is characterized in that a temperature-increasing device is positioned in the casing. The utility model has the advantages of high solubility and facilitation of transforming the prior art.
Description
Technical field
The utility model belongs to a kind of Melamine Production equipment, is specifically related to a kind of crude product of melamine solubilising device.
Background technology
Trimeric cyanamide is a kind of white crystals body, and synthetic method generally adopts Wyler's process, and Wyler's process generally is divided into high-pressure process, low-pressure process and normal pressure catalysis method.The basic procedure that the normal pressure catalysis method is produced trimeric cyanamide is: urea is under 0.1MPa pressure, with the ammonia is carrier, under 380～390 ℃ of temperature with silica gel as the catalyzer production of melamine, reaction gas is removed impurity through external filter, through obtaining crude product of melamine after the predacious organs crystallization, crude product of melamine is through dissolution filter, remove impurity after recrystallization obtain high-quality finished product.The dissolution process of prior art is to add an amount of ice acid and gac behind the crude product dissolving crude product of melamine, then by pump beat further dissolve toward dissolver after, filter to pressure filter, because the temperature in the dissolver is low, the solubleness of crude product of melamine is not high, cause the pressure filter load of postorder big, bits content height, consuming cost height.
Summary of the invention
The purpose of this utility model provides the high crude product of melamine solubilising device of a kind of solubleness.
The utility model is achieved through the following technical solutions: a kind of crude product of melamine solubilising device, comprise housing, and housing is provided with liquor inlet, and slag-drip opening, purified liquor outlet, blow-off valve is characterized in that being provided with in the housing heating device.
Described heating device is an interchanger, and interchanger is provided with steam inlet and condensation-water drain.
The utlity model has the solubleness height, be convenient to the advantage that prior art is transformed.
Description of drawings
Accompanying drawing is a synoptic diagram of the present utility model.
As shown in FIG.: 1 purified liquor outlet, 2 housings, 3 interchanger, 4 soup imports, 5 slag-drip openings, 6 condensation-water drains, 7 steam inlets.
Embodiment
As shown in drawings: housing 2 of the present utility model is provided with soup import 4, purified liquor outlet 1, and slag-drip opening 5 is provided with heating device in the housing 2, and heating device is an interchanger 3, and interchanger 3 is provided with steam inlet 7 and condensation-water drain 6.
During the utility model work, crude product of melamine is transported in the housing 2 by soup import 4, in interchanger 3, pass through high-temperature steam by steam inlet 7, the housing inner liquid medicine is heated, increase solubleness, the soup of finishing dissolution process is transported to next procedure by purified liquor outlet 1, and the steam after the cooling is discharged interchanger by condensation-water drain 6.
Claims (2)
1. a crude product of melamine solubilising device comprises housing, and housing is provided with liquor inlet, and slag-drip opening, purified liquor outlet, blow-off valve is characterized in that being provided with in the housing heating device.
2. crude product of melamine solubilising device according to claim 1 is characterized in that described heating device is an interchanger, and interchanger is provided with steam inlet and condensation-water drain.
