Description
Technical field
The utility model relates to the processing technology of gypsum, particularly a kind of alpha semi-hydrated gypsum
Production unit.
Background technology
At present, with the powdery dihydrate gypsum is that the maturation process of raw material production alpha semi-hydrated gypsum has only " liquid phase method ", it is after the powdered dihydrate gypsum is put into reactor and carried out the High Temperature High Pressure boiling, to carry out drying and secondary grinding again, can obtain the alpha semi-hydrated gypsum powder.This traditional " liquid phase method " produces the alpha semi-hydrated gypsum powder, its dehumidification system equipment price costliness, and energy consumption is very high, moves very complicated.If the alpha semi-hydrated gypsum slurries that no longer will react good carry out drying, direct pouring becomes plastering, not only can save the investment of drying plant, but also save energy.But because " liquid phase method " produce to need a condition of high voltage, therefore, prior art all is to adopt a kind of airtight, reactor that can bear and can constantly stir, the interruption production of a still one still.If be used for the continuous production of plastering (as gypsum block, Thistle board etc.), just nearly tens small-sized reactors must be set, still slurries are poured into a mould once.Facility investment is big, it is wide to take up an area of, complicated operation, labour intensity height.If the employing large-size reactor, after the alpha semi-hydrated gypsum slurries were produced, reactor can not be produced immediately next time, but as storage tank, not only efficient is low, kept slurries in the still and can not reduce and solidify but also will consume a large amount of energy.
According to the characteristics of alpha semi-hydrated gypsum production technique, its reacting by heating is divided into two processes: the one, and rapid increasing temperature and pressure reaches dihydrate gypsum and can slough one of them hypocrystalline water, begin to produce alpha semi-hydrated gypsum crystalline working temperature and vapor pressure; The 2nd, under this working temperature and vapor pressure condition, keep for some time, make the crystal growth of alpha semi-hydrated gypsum good, obtain high-quality alpha semi-hydrated gypsum.In above-mentioned two processes, they are different to the Heating temperature requirement of medium.For example, when heating medium was thermal oil, it is higher that first crosses the range request Heating temperature, can reach about 300 ℃, and second process then requires Heating temperature lower, is no more than 230 ℃.What prior art adopted is single unit system, because entire reaction course is only carried out in a reactor, the temperature of heating medium is low, long reaction time, the temperature height of heating medium, influential to the alpha semi-hydrated gypsum quality of producing.Therefore, not only efficient is low, energy consumption is high, and poor product quality.In addition, because the temperature of dihydrate gypsum slurries is being can not produce vapor pressure below 100 ℃, be heated to 100 ℃ from supplied materials, can carry out in non-pressure vessel, therefore, prior art adopts the single reaction equipment of energy bearing certain pressure uneconomical.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of continuous production equipment of alpha semi-hydrated gypsum is provided, and the reaction unit that adopts three kinds of different heating condition and pressure condition and be interconnected in entire reaction course has rationally used heat energy; And the mode that adopts the high-pressure pump feed, realized continuous production, this has not only improved production efficiency, and has saved the energy.
Task of the present utility model is achieved through the following technical solutions:
A kind of continuous production equipment of alpha semi-hydrated gypsum, it is characterized in that: described continuous production equipment is made up of drying installation four parts of separating of normal pressure preheating container, high pressure warming device, temperature-controlling reaction apparatus, semi-hydrated gypsum and water, and interconnect with pipeline, wherein be provided with high-pressure pump between normal pressure preheating container and the high pressure warming device.
The structure of described normal pressure preheating container, high pressure warming device, temperature-controlling reaction apparatus is respectively conventional reactor.The type of heating of described normal pressure preheating container, high pressure warming device, temperature-controlling reaction apparatus can be by thermal oil, steam, hot blast etc. carry out indirect heating or be to carry out direct heating by flame, microwave etc.Described separation drying installation is the airtight cylindrical shell of a setting, the water vapor suction channel is arranged at the top, the bottom has alpha semi-hydrated gypsum powder suction channel, cylindrical shell top that the shower nozzle that stretches into the intravital discharge slurry of tube from temperature-controlling reaction apparatus is arranged, and there is the heat tracing layer cylindrical shell outside.Described normal pressure preheating container, high pressure warming device, temperature-controlling reaction apparatus can form by single or multiple popular response stills are continuous according to the requirement in reaction times.
The utility model compared with prior art has the following advantages and beneficial effect:
The utility model is made up of drying installation four parts of separating of normal pressure preheating container, high pressure warming device, temperature-controlling reaction apparatus, semi-hydrated gypsum and water that pipeline is communicated with, wherein between normal pressure preheating container and the high pressure warming device high-pressure pump is arranged, can make heated dihydrate gypsum slurries in the normal pressure preheating container, pump in the high pressure warming device, the high pressure warming device reaches the slurries of temperature of reaction and is then sent into temperature-controlling reaction apparatus simultaneously after replenishing new slurries.They all can be by indirect heating such as thermal oil, steam, perhaps by direct heating such as microwave, firepower, the Heating temperature of normal pressure preheating container and high pressure warming device is higher, and the temperature-controlling reaction apparatus Heating temperature is lower, and semi-hydrated gypsum and the intravital temperature of water sepn drying installation tube are more than 100 ℃.Because above-mentioned conversion unit is according to the reacting by heating requirement of alpha semi-hydrated gypsum reality, adopt the reaction unit of different Heating temperature with different pressure-bearing conditions, and the mode that adopts the high-pressure pump feed, realized the production of reasonable continuous formula, make it mainly can to utilize the heat energy of reacting slurry self and pressure that the alpha semi-hydrated gypsum of output is carried out drying, therefore, the utlity model has production efficiency height, low power consumption and other advantages.
