Abstract

The utility model provides an efficient recycling device of alcohol production liquid waste. The device comprises a pipeline, and a solid-liquid separator, a liquid waste storage tank, a pump, a nanofiltration tube filter and a high-concentration suspended matter groove, which are connected in sequence through the pipeline, wherein the nanofiltration tube filter is connected with a clear liquid pipeline for introducing the recycled clear liquid into a production system, and high-pressure back flushing air used for back flushing the high-concentration suspended matters adhered on the pipe wall of the nanofiltration tube filter is connected on the clear liquid pipeline.. The efficient recycling device provided by the utility model can reduce the concentration of the liquid waste discharged during the alcohol production process to about 2000mg/l at a good state after the solid-liquid separation and settlement treatments, and the waste clear liquid is filtered by the special nanofiltration tube filter to further separate the suspended matters in the waste clear liquid so as to reduce the concentration of the suspended matters in the waste clear liquid to be lower than 50 mg/l.

Description

Ethanol produce waste liquid high efficiente callback device
Affiliated technical field
The efficient recycling method of waste liquid in a kind of ethanol produce process; Be used for the effective reuse of high-level efficiency of ethanol produce process waste liquid; Can significantly reduce the quantity discharged and reduction liquid waste disposal amount of waste liquid, belong to starchy material and produce the waste liquid recovery of alcohol and utilize the field.
Background technology
In traditional ethanol produce process, can produce a large amount of waste liquids, the reuse of treated waste liquid is generally about 30% in process of production; Some manufacturer even can't reuse, remaining 70% waste liquid is normally handled through evaporation concentration or through biochemical methods such as aerobic-anaerobic or the like approach, and which kind of processing mode no matter the waste liquid of these generations use; All to consume a large amount of heat energy or electric energy; And once investment is bigger, brings heavy processing burden for ethanol produce producer, if reduce cost of investment and the consumption that reduces the energy; Just must manage to increase the reuse amount of waste liquid; And the major cause that traditional waste liquid reuse amount is difficult to improve is that the waste liquid solid-liquid separation is not thorough, and suspension content is high in the waste clear solution after the separation; If want to reduce the content of suspended substance, just need the production capacity of reduction equipment, thereby the investment that has improved equipment and auxiliary facility is arranged, further increased energy consumption.Problem between above existence; We have invented a kind of waste clear solution filter method that adopts nanofiltration; The reuse amount of waste liquid is brought up to more than 80%; The waste liquid amount that need handle is less than 20% only, has reduced the cost of investment and the energy consumption level of liquid waste treating apparatus in the ethanol produce process significantly.
The utility model content
The purpose of the utility model is to the deficiency of prior art and the problem of existence; Adopt the waste clear solution filter method of nanofiltration; Accomplish the processing of waste clear solution suspended substance, the concentration of handling the back suspended substance can have original 2000mg/l to be reduced to 50mg/l and a kind of ethanol produce waste liquid high efficiente callback device is provided.
The utility model is for realizing that above-mentioned purpose adopts following technical scheme:
A kind of ethanol produce waste liquid high efficiente callback device; It is characterized in that: comprise pipeline and the solid-liquid separating machine that is linked in sequence through pipeline, waste tank, pump, nanofiltration pipe strainer, high concentration suspended matter groove; Said nanofiltration pipe strainer is connected with introduces the clear liquid pipeline of production system with reclaiming clear liquid, connects the high pressure blowback wind of recoil attached to the high concentration suspended matter on the nanofiltration pipe strainer tube wall on the clear liquid pipeline.
Said solid-liquid separating machine is connected the feed drying plant with the high concentration suspended matter groove.
Be provided with valve on the pipeline on the pipeline on the pipeline on the pipeline between said solid-liquid separating machine and the waste tank, between waste tank and the pump, between nanofiltration pipe strainer and the high concentration suspended matter groove, between nanofiltration pipe and high pressure blowback wind and the production system.
The utlity model has following beneficial effect:
The utility model can be with after waste liquid process solid-liquid separation of discharging in the ethanol produce process and the sedimentation; Under good state usually about 2000mg/l; These waste clear solutions are passed through a special nanofiltration pipe strainer again; Suspended substance in its waste clear solution is further separated, reach the waste clear solution suspended substance at last and be lower than 50mg/l.
Description of drawings
Fig. 1 is the system construction drawing of the utility model;
1 is that nanofiltration pipe strainer, 2 is that pipeline, 3 is that solid-liquid separating machine, 4 is that high concentration suspended matter groove, 5 is that valve, 6 is that waste tank, 7 is a pump among the figure.
Embodiment
A kind of ethanol produce waste liquid high efficiente callback device; Comprise solid-liquid separating machine, waste tank, pump, nanofiltration pipe strainer, high concentration suspended matter groove that pipeline and pain piping are linked in sequence, said nanofiltration pipe strainer is provided with and is used for the pipeline of the clear liquid introducing production system that reclaims clear liquid and the clear filtrate that is used to recoil are cleaned the high pressure blowback wind attached to the high concentration suspended matter on the nanofiltration pipe strainer tube wall.
Be provided with valve on the pipeline on the pipeline on the pipeline on the pipeline between said solid-liquid separating machine and the waste tank, between waste tank and the pump, between nanofiltration pipe strainer and the high concentration suspended matter groove, between nanofiltration pipe and high pressure blowback wind and the production system.
In the waste tank after alcohol distillation waste liquid process solid-liquid separation; Directly extracting waste liquid squeezes in the nanofiltration pipe strainer; Waste liquid suspended substance major part in through the process of nanofiltration pipe has been blocked in the nanofiltration pipe; Clear liquid will be through the nanofiltration pipe, obtains the very low clear liquid of concentration of suspension at the opposite side of nanofiltration pipe, and these account for the clear liquid direct reuse of total amount more than 80% in the middle of the process of ethanol produce.Along with the lengthening of filtration time, concentration of suspension in the nanofiltration pipe can constantly improve, reach certain state after; Can the suspended substance of its high density dropped in the high concentration suspended matter groove along tube wall through with a spot of clear filtrate recoil, the high concentration suspended matter of collecting be directly delivered to the feed drying oven; Solid ingredient with the waste liquid solid-liquid separation of front obtains is dried; Use as feed, improved the yield of feed, reduced the cost of investment of liquid waste disposal and the energy consumption of processing.
Adopt the utility model; After the waste liquid process solid-liquid separation and sedimentation of discharging in the ethanol produce process; Under good state usually about 2000mg/l; Again through a special nanofiltration pipe strainer, the suspended substance in its waste clear solution is further separated these waste clear solutions, reach the waste clear solution suspended substance at last and be lower than 50mg/l.
