Description
Technical field
The utility model relates to a kind of evaporimeter, especially relates to a kind of MVR high-efficiency evaporator.
Background technology
In known technical field, MVR is the abbreviation of steam mechanical recompression (mechanical bapor recompression).MVR is the energy that re-uses it self indirect steam of producing, thereby reduces a power-saving technology of the demand of the energy to external world.As far back as the sixties, Germany and France are successfully used for this technology the fields such as chemical industry, food, papermaking, medicine, desalinization and sewage disposal.
In Multi-effect Evaporation Processes, the indirect steam of a certain effect of evaporimeter can not, directly as this effect thermal source, can only be served as the thermal source of inferior effect or inferior several effects.As must be additionally given its energy as this effect thermal source, its temperature (pressure) is improved.Steam jet pump can only compression section indirect steam, and mvr evaporimeter is all indirect steams in compressible evaporimeter.Solution, in a falling film evaporator, circulates in heating tube by Matter Transfer pump.Initial steam is given heat outside pipe with live steam, solution ebuillition of heated is produced to secondary vapour, and the secondary vapour of generation is sucked by turbine boosted fan, and after supercharging, secondary stripping temperature improves, and enters heating clamber circulating and evaporating as heat source.After normal startup, turbo-compressor sucks indirect steam, becomes heating steam after supercharging, carries out continually circulating and evaporating like this.It is that the steam of low-temperature level is compressed through compressor that the moisture evaporating finally becomes its course of work of condensed water discharge evaporimeter, and temperature, pressure improve, and heat content increases, and then enters heat exchanger condensation, to make full use of the latent heat of steam.Except start up, in whole evaporation process without raw steam from evaporimeter indirect steam out, compress through compressor, pressure, temperature raise, heat content increases, then deliver to the heating clamber of evaporimeter and be used as heating steam use, make feed liquid maintain fluidized state, heating steam itself is condensed into water.Like this, originally will just be fully utilized by discarded steam, and reclaimed latent heat, and improved again the thermal efficiency, the economy of raw steam is equivalent to 30 times of multiple-effect evaporation.For making the manufacture of vaporising device simple and easy to operate as far as possible, often use the centrifugal recompression device of single-action, can be also high pressure positive blower or turbine compressor reducer.These machines are higher to its volume flow in 1:2 compression ratio range 11.2.For low evaporation rate, also can use piston compressor, slide vane compressor or helical-lobe compressor.
