Description
Technical field
The utility model relates to a kind of triple effect falling film evaporator with zero effect separation chamber, belongs to the food processing machinery and equipment technical field.
Technical background
Evaporimeter is the large-scale and important equipment in the starch sugar industry, and evaporimeter develops into present triple effect, four-effect evaporator by initial single effect evaporator, even also has quintuple effect evaporator.Evaporimeter commonly used is triple effect and quadruple effect, and newly going up production line generally all is to use four-effect evaporator, substantially all is triple effect evaporator for old production line.At present, because the profit of starch sugar reduces, belong to the small profits product, can only improve production capacity for striving for more profit.The production technology of starch sugar reaches its maturity, and production equipment is constantly updated simultaneously, for precondition has been created in the raising of production capacity.But the evaporation capacity of evaporimeter is certain, and its production capacity improves limited, and the production capacity that has greatly restricted the starch sugar industry improves, and the evaporimeter investment is higher, changes evaporimeter unrealistic.For improving production capacity, each starch sugar enterprise is all carrying out the technology and equipment transformation.Therefore, by existing triple effect falling film evaporator is carried out analytic demonstration, take the mode of small investment instant effect to transform, increase by zero effect separation chamber and improve evaporability, increase production capacity.
The charging flow process of adding the triple effect evaporator of zero effect is: feed liquid to be evaporated by plate type heat exchanger and indirect steam heat exchange after, entering zero effect separation chamber separates, the steam that produces is taken away by vavuum pump, and feed liquid is concentrated, and then enters original triple effect evaporator and concentrates.
Summary of the invention
For the deficiency of existing equipment production capacity, the utility model provides a kind of transformation simple, and cost of manufacture is low, and is easy to operate, and can significantly improve the production capacity of existing triple effect falling film evaporator.
The technical solution of the utility model is as follows:
A kind of triple effect falling film evaporator with zero effect separation chamber, comprise plate type heat exchanger, zero effect separation chamber, triple effect falling film evaporator, the indirect steam entrance of plate type heat exchanger is connected with indirect steam, zero effect separation chamber charging aperture of the material liquid outlet of plate type heat exchanger and zero effect separation chamber links to each other, zero effect separation chamber charging aperture is connected with the material liquid outlet that plate type heat exchanger goes out, and zero effect separation chamber discharging opening is connected with the triple effect falling film evaporator.
The top of described zero effect separation chamber is provided with the vacuum connector that is connected with vacuum line.
The course of work of the present utility model is as follows:
Treat that steaming liquid enters plate type heat exchanger through treating the import of steaming liquid, discharge by material liquid outlet with the indirect steam heat exchange, indirect steam enters plate type heat exchanger through the indirect steam entrance, discharges by condensation-water drain with the feed liquid heat exchange; Treat that steaming liquid enters zero effect separation chamber through zero effect separation chamber charging aperture and carries out gas-liquid separation after the heat exchange, the steam of generation is taken away by vavuum pump through the vacuum connector, and feed liquid enters triple effect evaporator through zero effect separation chamber discharging opening.After adding zero effect separation chamber, the evaporated water of former triple effect evaporator rises to 11 tons by 8 tons, does not consume initial steam.Compare with four-effect evaporator, evaporation capacity is suitable, and energy consumption is low.
Beneficial effect is: of the present utility model simple in structure, cost of manufacture is low, and is easy to operate, significantly improves evaporability, can utilize indirect steam, and operating cost is low, solved the little problem of existing evaporator evaporation ability.

Specific embodiment
Below in conjunction with drawings and Examples the utility model is described further, but is not limited to this.
Embodiment: a kind of triple effect falling film evaporator with zero effect separation chamber, as shown in Figure 1, comprise plate type heat exchanger (1), zero effect separation chamber (2), triple effect falling film evaporator (3), the indirect steam entrance (4) of plate type heat exchanger (1) is connected with indirect steam, zero effect separation chamber's charging aperture (8) of the material liquid outlet (7) of plate type heat exchanger (1) and zero effect separation chamber (2) links to each other, zero effect separation chamber's charging aperture (8) is connected with the material liquid outlet (7) that plate type heat exchanger goes out, and zero effect separation chamber's discharging opening (9) is connected with triple effect falling film evaporator (3).
The top of described zero effect separation chamber (2) is provided with the vacuum connector (10) that is connected with vacuum line.
The course of work of the present utility model:
Take the triple effect evaporator that per hour evaporates 8 tons of water yields as example, the heat exchange area of plate type heat exchanger is 40m
2, the zero effect diameter 1m of separation chamber highly is 2m, and indirect steam pipeline diameter is 108mm, and the feed liquid pipeline is 76mm.Treat that steaming liquid enters plate type heat exchanger through 6, discharge by 7 with the indirect steam heat exchange, indirect steam enters plate type heat exchanger through 4, discharges by 5 with the feed liquid heat exchange; Treat that steaming liquid enters zero effect separation chamber through 8 and carries out gas-liquid separation after the heat exchange, the steam of generation is taken away by vavuum pump through 10, and feed liquid enters triple effect evaporator through discharging opening 9.After adding zero effect separation chamber, the evaporated water of former triple effect evaporator rises to 11 tons by 8 tons, not handy initial steam.Compare with four-effect evaporator, evaporation capacity is suitable, and energy consumption is low.
