Description of drawings
Fig. 1 is used for the MVR plate evaporation system schematic that sweet mellow wine concentrates.
The specific embodiment
Referring to the MVR plate evaporation system that sweet mellow wine concentrates that is used for shown in Figure 1, it comprises firsts and seconds plate type preheater (two sections integral type preheaters, one section can be regarded as one-level plate type preheater 111, another section can be regarded as secondary plate type preheater 112) 11, three grades of board-like preheaters 12, plate-type evaporator 21, vapour liquid separator 22, cyclone separator 23, centrifugal vapour compression machine 4, condenser 5, fixed gas jar 6, vavuum pump 7, compensator 8 etc.
The discharging opening of the material channel of three grades of preheaters and the feeding inlet of plate-type evaporator; The discharging opening of plate-type evaporator and the feeding inlet of cyclone separator; High steam communicates with the air intake of plate-type evaporator; The top venthole of cyclone separator communicates with the import of vapour compression machine, the air intake of the outlet fishplate bar formula evaporimeter of vapour compression machine; The condensation-water drain of plate-type evaporator communicates with the condensed water import of vapour liquid separator; The top venthole of vapour liquid separator links to each other with the air intake of condenser, and the condensation-water drain of condenser communicates with the condensed water import of fixed gas jar, and the top venthole of fixed gas jar links to each other with vavuum pump.
The feeding inlet of the material channel of the discharging opening of the material channel of one-level preheater and secondary preheater, the feeding inlet of the material channel of the discharging opening of the material channel of secondary preheater and three grades of preheaters, the outlet of finished product materials communicates with the import of the heating agent passage of one-level preheater, and the bottom liquid outlet of vapour liquid separator communicates with the import of the heating agent passage of secondary preheater; The import of the heating agent passage of three grades of preheaters communicates with the venthole of vapour compression machine.
The major parameter that uses native system that sweet mellow wine is concentrated: sweet mellow wine inlet amount 8.4t/h, evaporation capacity 5t/h, input concentration 22BX, discharging concentration requirement 54BX, vapour compression machine design conditions: 70 ℃ of intake air temperature, 80 ℃ of delivery temperatures, the about 160KW of installed power.
The main technique flow process: sweet mellow wine at first enters compensator from last procedure, and the liquid level in the compensator is controlled by float-controlled valve.Send into the firsts and seconds plate type preheater by product pump afterwards, material raises through the preheat temperature that concentrates back material and condensed water in the firsts and seconds plate type preheater, enter three grades of board-like preheaters subsequently, the preheating of material process compressor steam in three grades of board-like preheaters, temperature of charge is elevated to and approaches boiling temperature, after entering plate-type evaporator, be subjected to the heating of steam again and seethe with excitement, vaporize, the material that this moment, vapour-liquid was mixed comes out from the discharging opening of evaporimeter, then enters cyclone separator.Material is under action of centrifugal force, liquid flies to wall and accumulates in the bottom then, steam is then extracted the import (steam suction inlet) that (being the indirect steam of plate-type evaporator) enters centrifugal vapour compression machine out by the top of separator, indirect steam is compressed into designing requirement in compressor after, discharge from outlet, be introduced into the evaporimeter air intake, use as heating steam.The material of extracting out from the cyclone separator bottom has been concentrated to the concentration of designing requirement, is used to deliver to next procedure behind the pre-thermal material of one-level plate type preheater.Concentration process is to carry out under the negative pressure state of being kept by vavuum pump.And the superfluous steam of part then enters condenser to discharge after by water cooling, and cooling water is the water system from factory.
