Embodiment 1

[0015] The heating system of the biogas fermentation tank in this example is as follows: figure 1 As shown, it is mainly composed of a regulating pool 1 and a heat exchanger 11. The heat exchanger 11 is evenly arranged in the regulating pool 1, and the heat exchanger 11 is connected with the hot water circulation pipe 14; , the top of the regulating tank 1 is provided with a thermal insulation cover 12; the regulating tank 1 is provided with a feed pump 3, and the feed pump 3 is connected to the fermenter feed port 8 through the fermenter feed pipe 9; the upper part of the regulating tank 1 is provided with a regulating Pool inlet 13. A stirrer 10 is arranged in the adjustment tank 1 .

[0016] The feed port 8 of the fermenter is set at the bottom of the fermenter 4, the outer side of the fermenter 4 is provided with a fermenter insulation layer 5, the bottom of the fermenter 4 is provided with a discharge port 6 of the fermenter, and the top of the fermenter 4 is provided wi...

Embodiment 2

[0021] The biogas fermentation tank warming system of this example is the same as the first embodiment except that the agitator 10 is not provided.

[0022] In the operation of this example, after the fermentation material enters the adjustment tank 1 from the feed port 13 of the adjustment tank, it is connected to the hot water circulation pipe 14, and the heat exchange medium passes through the hot water circulation pipe 14 to bring heat to the heat exchanger 11 for heating with the fermentation liquid. exchange. All the other are the same as embodiment one.

Abstract

The invention relates to a biogas fermentation tank heating system, belonging to the field of development of renewable energy sources. The biogas fermentation tank heating system comprises a regulation tank (1) and heat exchangers (11), wherein the heat exchangers (11) are uniformly distributed in the regulation tank (1) and are connected with a hot water circulating pipe (14); insulation layer (2) is arranged on the outer side of the regulation tank (1), and an insulation cover plate (12) is arranged on the top of the regulation tank (1); a feeding pump (3) is arranged in the regulation tank (1) and is connected with a fermentation tank feeding hole (8) through a fermentation tank feeding pipe (9); a regulation tank feeding hole (13) is formed in the upper part of the regulation tank (1). According to the biogas fermentation tank heating system, the defects of weak heating purpose, high heat exchange equipment investment, low heating efficiency and high maintenance management cost in the prior art are overcome; the heating efficiency and the reliability are high, a heat exchanger is convenient to maintain and manage, the equipment cost and the operation cost of the heating system can be lowered, and the fermentation temperature in a fermentation tank can be effectively guaranteed.

Description

technical field [0001] The invention belongs to the field of renewable energy development, and in particular relates to a biogas fermentation tank heating system. Background technique [0002] Temperature is a key factor in biogas fermentation. Low fermentation temperature and low anaerobic microbiological properties lead to low project operation efficiency and low energy efficiency. Generally, large and medium-sized biogas digesters adopt warming measures to maintain the optimum fermentation temperature of the biogas slurry. At present, in large and medium-sized biogas projects, the temperature increase measures basically adopt the temperature increase of the fermentation tank. It is often used to increase the temperature by adding a heat exchanger inside the fermenter - increasing the temperature inside the tank wall, or setting a coil tube in the tank wall and the insulation layer to increase the temperature - increasing the temperature outside the tank wall. Warming i...
