Problems solved by technology

[0002] During the operation of biogas digesters, fillers are generally required. The ingredients of fillers are generally straw and cow dung. Relatively speaking, straw comes from a wide range of sources, while cow dung is generally purchased from farms. With the popularity of biogas digesters, the price of cow dung has been rising repeatedly. In some areas, it has reached 50 yuan per cubic meter, and the cost of cow dung has become the main cost of maintaining the operation of the biogas digester. However, there have been no reports of biogas digesters that no longer need cow dung to add gas after the successful operation of the biogas digester.

Embodiment

[0011] The start-up of the two-step fermentation biogas digester (using corn stalks as raw material 8m 3 biogas tank as an example)

[0012] 1. Ingredients: inoculum, raw material, water = 1:2:5, that is, 1m 3 Inoculum, 2m 3 Straw, 5m 3 water.

[0013] 2. Filling:

[0014] Before filling in the one-step fermentation tank 12, check whether the check valve 10 on the grating 15 on the feed pipe 23 and the discharge pipe 31 meets the requirements, and then fill the one-step fermentation tank 12 with the stalks prepared in layers. Each layer of filling will be stepped on until it is full. In the process of filling, 14 kilograms of ammonium bicarbonate and 1.5 kilograms of biological fungicide should be put into the second-step fermentation tank 29 to add water in proportion to make it 5m 3 The nutrient solution is pumped into the one-step fermentation tank 12 with a submersible sewage pump, and the raw materials are retting, and when the retting raw materials are produced aci...

Abstract

The invention provides a high-efficiency household hydraulic pressure methane tank capable of utilizing various straws and human and animal excreta for two-step fermentation aiming at the technical defects of the prior rural household hydraulic pressure methane tank. The methane tank mainly comprises a one-step fermentation pool, a two-step fermentation pool, a feeding pipe and a discharging pipe, has the characteristics of scientific design and low manufacturing cost, and can be operated normally only by the addition of the straws after dairy manure is thrown into the methane tank at a time.

Description

technical field [0001] The invention relates to a two-step fermentation technology of a biogas pit, which belongs to the field of comprehensive utilization of new energy, in particular to a two-step fermentation biogas pit. Background technique [0002] During the operation of biogas digesters, fillers are generally required. The ingredients of fillers are generally straw and cow dung. Relatively speaking, straw comes from a wide range of sources, while cow dung is generally purchased from farms. With the popularity of biogas digesters, the price of cow dung has continued to rise. In some areas, it has reached 50 yuan per cubic meter. The cost of cow dung has become the main cost of maintaining the operation of biogas digesters. However, there have been no reports of biogas digesters that no longer need cow dung to add gas after the successful operation of the biogas digesters. Contents of the invention [0003] The invention aims at the technical deficiency of the existin...
