Embodiment Construction

[0084] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0085] Such as figure 1 , 5 As shown, the biogas fermentation system includes a fermentation tank body 10, a gas storage plate 20, and a water pressure room 40. The water pressure room 40 is connected to the upper part of the fermentation tank body 10 through water pipes, and the gas storage plate 20 is fixed in the fermentation tank body 10. The area between the left end of the gas storage plate 20 and the fermentation tank body 10 is the feed inlet 12, the ar...

Abstract

The invention discloses an excessive-biogas collecting and exhausting method. The excessive-biogas collecting and exhausting method comprises the steps of excessive-biogas collection and oxygen supply during exhausting biogas. In the step of excessive-biogas collection, a gas guide piston is controlled to open and close by utilizing the same gas pressure pushing the gas guide piston of which the effective areas of the upper end and the lower end are different; in the step of oxygen supply during exhausting biogas, an oxygen pump is driven by using biogas pressure as power to work so as to supply oxygen to a pond, so that the excessive-biogas collecting and exhausting method is non-pollution, environment-friendly and energy-saving.

Description

technical field [0001] The invention relates to a method for collecting and discharging excessive methane. Background technique [0002] The latest national standard for biogas digesters released in 2002 includes 5 types of ponds, namely hydraulic cylindrical biogas digesters, separated floating cover biogas digesters, meandering cloth biogas digesters, prefabricated block (cylindrical) biogas digesters and ellipsoidal biogas digesters. Biogas digester: The cylindrical biogas digester is a pipe-type biogas digester. Fermentation raw materials enter the fermentation pipeline to ferment to produce biogas, and accumulate in the fermentation pipeline, which is easy to cause blockage of the fermentation pipeline; if the blockage is deep, it is usually used to clear the fermentation pipeline All sundries inside, and then poke through the rod body. [0003] The biogas slurry produced by the fermentation of animal manure is tasteless after fermentation and the fertilizer effect aft...
