Description
Technical field
The utility model relates to a kind of crystallizing evaporator, relates in particular to a kind of quadruple effect crystallizing evaporator.
Background technology
At present, the quadruple effect crystallizing evaporator, be mainly used in the evaporation high boiling medium, comprise an effect heater and a 1st effective evaporator that is communicated with successively, two imitate heater and 2nd effect evaporator, triple effect heater and triple effect evaporation crystallizer and steam-water separator, cooler, drop pan, vavuum pump, below the triple effect evaporation crystallizer, be provided with brilliant liquid discharging pump, feed pump is connected with evaporimeter with each heater with valve by connecting pipe, between heater and evaporimeter, also be provided with circulating pump, quadruple effect heater and four-effect evaporator serial connection back are communicated with 1st effective evaporator, difference according to technological process is divided into cross-flow multiple-effect evaporation crystallizer and countercurrent multi-effect evaporation crystallizer, but they all have only a crystallization leg, its shortcoming is as evaporation sodium chloride, the sodium sulphate fractional crystallization, other several effects can produce the fouling plugging, and energy consumption is big, especially when the evaporation high boiling medium, as evaporate separation temperature at 80 ℃ of-140 ℃ of materials, can only adopt cross-flow, adverse current equipment, also exist evaporation rate slow, the shortcoming that steam consumption quantity is big.In addition, the forced circulation pump that crystallizing evaporator is joined all is the base centrifugal pump, needs 4 elbows, and its shortcoming is big to the equipment running resistance, reduces flow velocity and increases energy consumption.
Summary of the invention
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, and a kind of quadruple effect crystallizing evaporator of less scaling, good energy-conserving effect is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the quadruple effect crystallizing evaporator, comprise an effect heater and a 1st effective evaporator that is communicated with successively, two imitate heater and 2nd effect evaporator, triple effect heater and triple effect evaporation crystallizer and steam-water separator, cooler, drop pan, vavuum pump, below the triple effect evaporation crystallizer, be provided with brilliant liquid discharging pump, feed pump is connected with evaporimeter with each heater with valve by connecting pipe, between heater and evaporimeter, also be provided with circulating pump, quadruple effect heater and four-effect evaporator serial connection back are communicated with 1st effective evaporator, at 1st effective evaporator, four-effect evaporator, 2nd effect evaporator and triple effect evaporation crystallizer following respectively is provided with a crystallization leg.
The utility model beneficial technical effects is: because a plurality of crystallization legs work, the less scaling plugging of the utility model also can utilize indirect steam, and promptly an effect evaporation material concentration is rarer, being evaporated gas can be many, can be used as two thermals source of imitating, fast to two effect steaming firing rates, two imitate the gas that is evaporated, thermal source as triple effect, the gas that quadruple effect is evaporated is imitated as thermal source to two simultaneously, adopts following current technology, thereby also has the advantage of good energy-conserving effect.In addition, circulating pump of the present utility model is 90 angle circulating pumps, and because of 90 angle pump elbows are few, resistance is few, and the feed liquid outer circulation is increased flow velocity, reaches each second 2.6 meters flow velocitys, and heat-transfer effect increases, and evaporation rate improves.
Description of drawings
Fig. 1: structural representation of the present utility model;
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
As shown in Figure 1, the quadruple effect crystallizing evaporator, comprise an effect heater 1 and a 1st effective evaporator 2 that is communicated with successively, two imitate heater 3 and 2nd effect evaporator 4, triple effect heater 5 and triple effect evaporation crystallizer 6 and steam-water separator 7, cooler 8, drop pan 9, vavuum pump 10, below the triple effect evaporation crystallizer, be provided with brilliant liquid discharging pump 11, feed pump 12 is connected with evaporimeter with each heater with valve 14 by connecting pipe 13, between heater and evaporimeter, also be provided with circulating pump 15, quadruple effect heater 18 and four-effect evaporator 19 serial connection backs are communicated with 1st effective evaporator 2, at 1st effective evaporator 2, four-effect evaporator 19,2nd effect evaporator 4 and triple effect evaporation crystallizer 6 following respectively is provided with a crystallization leg 16.
Respectively be provided with a circulating pump 15 between an effect heater 1 and 1st effective evaporator 2, quadruple effect heater 18 and four-effect evaporator 19, two effect heaters 3 and 2nd effect evaporator 4, triple effect heater 5 and triple effect evaporation crystallizer 6, circulating pump 15 is 90 angle circulating pumps.
Its technological process is as follows:
