Description
Technical field
The utility model relates to the solution-treated equipment technical field, a kind of specifically high-efficiency and continuous crystallizing evaporator.
Background technology
Evaporimeter is to be widely used in fields such as food processing, concentration of juices, beverage production, Dairy Production, chemical industry, pharmaceutical industry, wastewater treatment, environment-friendly engineering.Concentration generates crystalline solid thereby wherein most of inorganic salts, organic salt product all need to reach capacity.Ordinary mould is divided into top vapor-liquid separation chamber, is the crystal basin below, after equipment operation a period of time, after reaching capacity the concentration crystallization, material reaches a constant volume, open the discharging pump discharging again, close discharging pump after the crystalline solid emptying again, thus discharging continuously.After discharging pump was closed, macrocrystalline cognition entered the pipeline that joins with discharging pump, and can't in time discharge this moment, thus cause the obstruction of discharge nozzle sometimes, and remove very trouble, and can make and produce delay, can't reach continuous operation.
Summary of the invention
The purpose of this utility model can satisfy continuous feed, discharge for providing a kind of, and crystalline solid is separated out a mouthful not susceptible to plugging continuous evaporative crystallization device.
The technical scheme that realizes the foregoing invention purpose is as follows:
The continuous evaporative crystallization device, comprise vapour liquid separator, floater is formed at the vapour liquid separator bottom, the floater bottom is connected with the crystal basin, the crystal basin is internally connected with the crystal discharge nozzle, and crystal discharge nozzle lower end is provided with discharging pump, and the crystal discharge nozzle is connected to the crystal tank bottom by circulation pipe, circulation pipe is provided with circulation pipe valve, discharging valve and discharging opening, and the crystal tank bottom is provided with agglomerate thing discharging opening.The vaporization chamber top is connected with vapour liquid separator by the vapour liquid-phase tube, the vaporization chamber bottom is connected with floater by pipeline, the pipeline that connects vaporization chamber and floater is provided with forced circulation pump, to improve heat transfer coefficient, be provided with the Separation of Solid and Liquid chamber in the floater, both sides, described Separation of Solid and Liquid chamber are provided with division board.Suspension enters after the vaporization chamber heating continuously, after vapour liquid separator separates, solution concentration is improved reach supersaturation formation crystalline solid, because the proportion of crystalline solid is greater than liquid (suspension), so the crystal rapid subsidence is to advancing the crystal basin, liquid (suspension) floats over above the crystal all the time, enter the crystal discharge nozzle, through discharging pump discharging then, can enter the circulation of crystal basin once more through circulation pipe, the circulation mouth of pipe circulates into to living the discharging mouth of pipe, in case the phenomenon that the discharging opening upper end is blocked by crystal occurs, causing can't continuous operation.
The utility model can satisfy continuous feed, the requirement of continuous pulp discharge (crystalline solid solution).Adopt forced circulation to form best cooperating between vaporization chamber and the crystallizer.Its inside is provided with Separation of Solid and Liquid chamber and division board, make crystal and clear liquid obtain effectively, separate fast, with the crystalline solid of growing up in the solution for continuous of satiety, effectively the avoid evaporating formation of chamber tubulation inner surface fouling (dirt) has improved the heat transfer coefficient of vaporization chamber greatly.Inner surface treatment.No dead angle, easily the crystalline solid liquation goes out, and to separate out that mouth is not subjected to stop up be most critical to crystalline solid when continuous or discontinuous operation.Which is provided with manhole, window, lamp hole, thermometer, vacuum meter, fluid level control device etc.
It is (anti-blocking that floater is provided with the Separation of Solid and Liquid chamber, antiscale) and the both sides division board, the liquid (suspension) that Figure 11 does not form crystal in this circulation through forced circulation pump once more through vaporization chamber circulation heating (see for details in the accompanying drawing floater to the arrow flow process of vaporization chamber), crystalline solid passes through the crystal discharge nozzle to discharging pump, enter circulation pipe again, arrive the crystal basin by circulation pipe then.Crystal discharge nozzle import department is provided with baffle plate (seeing Fig. 2 for details), thereby the effect of baffle plate is in order to prevent that discharging pump from shutting down back macrocrystalline thing and directly entering the crystal discharge nozzle and can't discharge and cause that crystalline solid stops up.The utility model also can be realized the multiple-effect evaporation crystallization
Macrocrystalline body in the crystal basin can be discharged from agglomerate thing discharging opening.
