Problems solved by technology

The water used to prepare the powder slurry in this method is additional water, and the steam in the cooking process is not collected and liquefied to prepare the powder slurry, which increases the cost investment. The method is saccharified, fermented and then distilled without cooling to produce ethanol Contains more impurities such as methanol

Embodiment 1

[0032] refer to figure 1 , this embodiment provides a liquid fuel liquid saccharification production device for electric power, including a liquefaction mechanism, a cooking mechanism connected to the liquefaction mechanism, a saccharification tank 9 connected to the cooking mechanism, and a saccharification tank 9 connected A cooling mechanism, a fermenter 13 connected to the cooling mechanism;

[0033]The liquefaction mechanism includes a primary preheating tower 1, a secondary preheating tower 3, and a liquefaction tank 4 connected to the secondary preheating tower in sequence; A heater 6 connected to a delivery pipeline provided with a liquefied material pump 5, a cooking column 7 connected to the heater 6, a primary flash tank 15 sequentially connected to the cooking column 7, a secondary flash Steam tank 14, three-stage flash tank 11.

[0034] The primary preheating tower 1 in the liquefaction mechanism is provided with a feed port, and the heater 6 is provided with a ...

Embodiment 2

[0038] refer to figure 1 , this embodiment provides a liquid fuel liquid saccharification production device for electric power. The difference from Embodiment 1 is that in this embodiment, the heater 6 is a spray heater to save steam, and the gas heat exchange module 8 is a condenser, and the remaining high-temperature steam output from the three-stage flash tank 11 is sent into the condenser to be condensed into a liquid with higher pressure, and the vacuum pump 2 extracts non-condensable gas to maintain the vacuum degree.

Embodiment 3

[0040] refer to figure 1 , this embodiment provides a liquid fuel liquid saccharification production device for electric power. The difference from Embodiment 2 is that in this embodiment, the cooling mechanism 12 is a wide-channel plate heat exchanger, which improves heat transfer efficiency and saves Energy, compact structure, small footprint.

Abstract

The invention discloses a liquid fuel saccharification production device and method for electric power, and belongs to the technical field of fuel production. The liquid fuel saccharification production device comprises a liquefaction mechanism, a cooking mechanism, a saccharification tank, a cooling mechanism and a fermentation tank, wherein the cooking mechanism is connected with the liquefaction mechanism; the saccharification tank is connected with the cooking mechanism; the cooling mechanism is connected with the saccharification tank; the fermentation tank is connected with the cooling mechanism; the liquefaction mechanism comprises first to N-stage preheating towers which are connected in sequence and a liquefaction tank connected with the N-stage preheating tower; the cooking mechanism comprises a heater connected with the liquefaction tank through a conveying pipeline provided with a liquefaction material pump, a cooking column connected with the heater, and a first to (N+1)-stage flash tanks connected sequentially with the cooking column; N is more than or equal to 2. Through adoption of a multi-stage heat recovery way, the consumption of steam is lowered, a very good liquefaction saccharification effect is achieved, and high ethanol purity is achieved.

Description

technical field [0001] The invention belongs to the technical field of fuel production, and in particular relates to a saccharification production device and method of liquid fuel liquid for electric power. Background technique [0002] In recent years, my country's renewable power has developed rapidly, and the installed capacity of renewable power such as photovoltaics, wind power, and hydropower has strongly promoted the continuous optimization of the domestic power supply structure. In comparison, the development of renewable liquid fuels in China is obviously lagging behind, and has become a prominent shortcoming of the current energy transformation, which urgently needs to be accelerated. Ethanol is an important basic industrial raw material. In the field of energy, it can also be used as a new fuel to replace gasoline. The biggest advantage of fermented alcohol as a fuel compared to gasoline is its renewability; currently the largest amount is used as fuel ethanol . ...
