Embodiment 1

[0054] A liquor factory produces Luzhou-flavor liquor. The daily output of distiller's grains is 200 tons, with a moisture content of 65-70%. Build a comprehensive utilization device for local treatment. The treatment process is attached figure 2 shown.

[0055] 1) The distiller's grains are sent to the biogas station via a belt conveyor, weighed and measured by a belt scale, and then poured into the silo;

[0056] 2) Use the shaftless screw conveyor at the tail of the silo to send it quantitatively and evenly to the slurry tank, where it is mixed and inoculated with the returning biogas slurry, and the temperature is adjusted to 56°C by using the hot water or cold water of the multi-supply system, and then use the screw pump Or the rotor pump is promoted to the anaerobic digestion tank I; the multi-generation system can be supplied as fuel by the biogas produced subsequently;

[0057] 3) In the anaerobic digestion tank I, the solid concentration is maintained at 8-12%, th...

Embodiment 2

[0064] A liquor factory produces Luzhou-flavor liquor, with a daily output of 400 tons of distiller's grains, with a moisture content of 65-70%. The main components are rice husks and grains (rice, sorghum, wheat, mung beans, glutinous rice, etc.) Build a comprehensive utilization device for local treatment. The treatment process is attached image 3 shown.

[0065] 1) The distiller's grains are sent to the biogas station by a dump truck, weighed and measured by a belt scale, and then poured into the silo;

[0066] 2) Use the shaftless screw conveyor at the tail of the silo to send it quantitatively and evenly to the slurry tank, where it is mixed and inoculated with the returning biogas slurry, and the temperature is adjusted to 40°C by using the hot water or cold water of the multi-generation system, and then the latent sewage is used to The pump or the rotor pump is lifted to the anaerobic digestion tank I; the multi-generation system can be supplied as fuel by the biogas...

Embodiment 3

[0074] A liquor factory produces Luzhou-flavor liquor, with a daily output of 600 tons of distiller's grains and a moisture content of 65-70%. The main components are rice husks and grains (rice, sorghum, wheat, mung beans, glutinous rice, etc.) Build a comprehensive utilization device for local treatment. The treatment process is attached Figure 4 shown.

[0075] Among them, the temperature is adjusted to 60°C in the slurry tank; the solid concentration in the anaerobic digestion tank I is kept at 15-25%, the temperature is controlled at 58±1°C, and high-temperature solid-state fermentation is carried out; the solid state in the anaerobic digestion tank II is The concentration is kept at 6-12%, the temperature is controlled at 55±1°C, and high-temperature solid-state fermentation is carried out.

[0076] The anaerobic digestion system produces about 70,000 cubic meters of biogas per day, which is directly supplied to coal-fired boilers without treatment to support combusti...

Abstract

The invention relates to a distillate spirit vinasse spot comprehensive utilization method. Distillate spirit vinasse is fed into an anaerobic digestor, anaerobic microorganisms are used for conducting fermentation treatment, degradable organisms are converted to biogas, the biogas serves as fuel of a boiler and a multiply combined cooling heating and power system and is purified to natural gas, a biogas fluid is subjected to solid-liquid separation, the biogas fluid and a biogas residue are obtained, the biogas fluid is refluxed and serves as an anaerobic digestor germ, redundant biogas fluid is discharged into a spirit factory sewage disposal system or serves as liquid fertilizer, the dried biogas residue serves as the fuel of the boiler, the produced steam is used for production, rice hull ash is used for agricultural production or production of other high value-added products, and the biogas residue can be processed to organic fertilizer and is used for agricultural production. By the aid of the method, the distillate spirit vinasse can be subjected to spot treatment in the spirit factory, raw materials cannot be transported for a long distance, water and chemical medicines are not required to be added during the production and treatment process, products can be applied in the spirit factory completely and are not affected by seasons and market requirements, and the system energy utilization efficient is high.

Description

technical field [0001] The invention relates to the technical field of distiller's grains treatment, in particular to a method for in-situ comprehensive utilization of distiller's grains. Background technique [0002] my country's liquor adopts solid-state fermentation and solid-state distillation production technology, which is a unique winemaking method in the world. Distiller's grains are by-products produced in the production process of liquor brewing. They are produced in large quantities. The main components are water, rice husks and grain fermentation residues. They have high volatile organic matter content, are acidic, and are easily corrupted. Currently, they are mostly used as feed for livestock and poultry. Or directly incinerate. Due to the high content of rice husk in distiller's grains and the poor quality of feed, livestock and poultry farming is easily affected by the market and seasonality, which brings instability to distiller's grains treatment. If the d...
