Abstract
The utility model provides a multi-effect evaporator system which comprises two or more evaporation stages, wherein feed liquid pipelines, which are connected in parallel to each other, are connected to the feed liquid outlet of each evaporation stage of the multi-effect evaporator system; and secondary steam pipelines, which are connected in parallel to each other, are connected to a secondary steam outlet of the multi-effect evaporator system and are connected into heat pump equipment. According to the multi-effect evaporator system, residual heat of secondary steam can be utilized completely, so as to reduce energy waste; and each evaporation stage can be maintained independently in case of blockage or failure without shutting down the whole system.
Description
Technical field
The utility model relates to a kind of evaporator system, and more particularly, the utility model relates to the Multi-effect evaporator system with a plurality of evaporation stages.
Background technology
Evaporimeter is widely used for the enrichment processing procedure of various materials, described material processing procedure such as the concentration of concentration, organic salt or the inorganic salts of alcohol waste mash evaporation process, corn steep liquor evaporation process, amino acids zymotic fluid etc.
Multi-effect evaporator system is the evaporimeter with at least two evaporation stages, and each evaporator part in these evaporation stages is in series arranged in order.In the multi-effect evaporator technical field, each evaporation stage is called one " effect ".
If Multi-effect evaporator system has two above stages, the first evaporation stage of this evaporimeter just is called as " effect " so, the second evaporation stage is called as " two effects ", each evaporation stage is by called after successively by that analogy: two effects, triple effect, quadruple effect, five effects etc., last evaporation stage is also referred to as " eventually effect ".
In the Multi-effect evaporator system that uses at present, no matter be multi-effect evaporator shell-and-tube or board-like, the flow duct of the treating material between the stages (each " effect ") is all with arranged in series, thereby so that each " effect " in series is combined into an integral body.
Adopt multi-effect evaporator to carry out in the material of evaporation process at needs, generally all contain some solable matter and partial suspended solid.In multi-effect evaporator, along with the process orientation of material along " eventually effect " from " effect " of upstream to downstream progressively flows downstream from the upstream, material is subject to the constantly evaporation process of reinforcement, thereby the concentration of material progressively improves, and simultaneously, evaporating temperature descends gradually.Because concentration improves, evaporating temperature descends and the variation of DDGS chemical characteristic, the concentration of suspended solid can improve gradually, and crystal can be separated out gradually.
Discharge after the direct condensation of water vapour of evaporating in the typical multi-effect evaporator use procedure, waste heat can not be fully used; Fouling occured in the surface when evaporimeter used, and stopped up in inside, feed liquid road, and the operation that must stop whole system being keeped in repair again, has prolonged the production cycle.
Summary of the invention
For overcome the fouling that exists in the prior art and stop up after need stop whole system and the waste heat problem of can not being fully used, the utility model provides a kind of improved Multi-effect evaporator system.
Basic technical scheme of the present utility model is: a kind of Multi-effect evaporator system for processing continuously feed liquid, described feed liquid are any in alcohol waste mash, corn steep liquor, amino acids zymotic fluid, yeast or the yeast extract waste liquid.Described Multi-effect evaporator system is with at least two evaporation stages of feed liquid pipeline series connection, consist of typical multi-effect evaporator, evaporation stage comprises evaporator part and vapour liquid separator parts, it is characterized in that described Multi-effect evaporator system is connected with feed liquid pipeline in parallel at each evaporation stage material liquid outlet of typical multi-effect evaporator.Described Multi-effect evaporator system is connected with indirect steam pipeline access heat-pump apparatus in parallel in the outlet of typical multi-effect evaporator indirect steam, and the indirect steam compression is treated to behind the compressed steam evaporator part from compressed steam pipeline access multi-effect evaporator in parallel.
Described Multi-effect evaporator system can be the 2nd effect evaporator system, triple effect evaporator system, four-effect evaporator system, quintuple effect evaporator system wherein a kind of.
During described Multi-effect evaporator system operation, when a certain evaporation stage needs repairing, can open the feed liquid pipeline in parallel on this effect evaporation stage and the last effect evaporation stage material liquid outlet, feed liquid is flowed out from feed liquid pipeline in parallel when last effect, flow into evaporator system through next bar feed liquid pipeline in parallel again, and without the evaporation stage of need maintenance; Close simultaneously this effect evaporation stage indirect steam pipeline in parallel and compressed steam pipeline in parallel, make steam without the evaporation stage of need maintenance, all the other evaporation stages still can continue operation, and do not need to close whole system.
The utility model provides a kind of Multi-effect evaporator system, and it is compared with traditional Multi-effect evaporator system, has significant advantage:
1) this Multi-effect evaporator system can take full advantage of the indirect steam waste heat, reduces the waste of the energy;
2) a certain evaporation stage of this Multi-effect evaporator system stops up or can keep in repair separately when breaking down, and does not need to close whole system.
Description of drawings
Fig. 1 is schematic diagram of the present utility model, take four-effect evaporator as example;
Material pipe (1), feed liquid pipeline in parallel (2,3,4,5), heat-pump apparatus (6), indirect steam pipeline (7,8,9 in parallel, 10), compressed steam pipeline (11,12,13 in parallel, 14), evaporator part (15,16,17,18), the vapour liquid separator parts (19,20,21,22), feed pump (23,24,25).
The specific embodiment
In order better to set forth the utility model Multi-effect evaporator system, below in conjunction with accompanying drawing, take four-effect evaporator as example, its tool present embodiment, structure, feature are described.
Multi-effect evaporator system comprises material pipe (1), feed liquid pipeline in parallel (2,3,4,5), heat-pump apparatus (6), indirect steam pipeline (7,8,9 in parallel, 10), compressed steam pipeline (11,12,13 in parallel, 14), evaporator part (15,16,17,18), the vapour liquid separator parts (19,20,21,22), several parts such as feed pump (23,24,25).
Evaporator part (15) consists of an effect evaporation stage with liquid/gas separator parts (19), evaporator part (16) consists of two effect evaporation stages with liquid/gas separator parts (20), evaporator part (17) consists of the triple effect evaporation stage with liquid/gas separator parts (21), and evaporator part (18) consists of the quadruple effect evaporation stage with liquid/gas separator parts (22).
When an effect evaporation stage need keep in repair, open feed liquid pipeline in parallel (2) and feed liquid pipeline in parallel (3), all the other each feed liquid closedown of pipeline in parallel, make feed liquid flow into feed liquid pipeline in parallel (2) from material pipe (1), again from feed liquid pipeline in parallel (3) flow through feed pump (23) pump into two the effect evaporation stages, make feed liquid without one the effect evaporation stage; And close indirect steam pipeline in parallel (7) and compressed steam pipeline in parallel (11), make steam all without an effect evaporation stage, can keep in repair an effect evaporation stage.
