Embodiment Construction

[0017] The specific technical solutions of the present invention will be further described below in conjunction with embodiments:

[0018] The five dry materials of clay or sand, limestone powder, iron ore powder, 425 grade acid cement, and solid sodium silicate are in weight percentage: clay or sand 60-70%, limestone powder 2-5%, iron ore powder 1-3%, 425 grade acid cement 15-25%, solid sodium silicate 5-10%, mix and grind to below 100 mesh, pour into the mixer, add 1.0-1.5 times the weight of the dry material and stir immediately; It can be used for about 5 minutes until it is sticky. It can be used for laying and wiping. After wiping, cover with 10 mesh glass cloth and wipe the last layer. It is very durable and can be used for more than 20 years. Under the same volume, the cost of using the present invention is 400 yuan per unit, while the cost of the existing biogas digester is 1,000 yuan per unit, which can save 600 yuan per unit.

Abstract

The invention relates to a low-cost marsh gas tank. The low-cost marsh gas tank is characterized in that: the weight percent of 5 dry materials of clay or sandy soil, limestone powder, iron ore powder, 425-level acid cement and solid sodium silicate is sequentially 60 to 70%, 2 to 5%, 1 to 3%, 15 to 25% and 5 to 10%; the 5 dry materials are mixed and ground to lower than 100 meshes, are poured into a stirring machine, and are then stirred immediately after water (the weight of the water is 1.0 to 1.5 times larger than that of the dry materials) is added till the state of sticky paste; the dry materials can be used after about 5 minutes and can be built or plastered; after the dry materials are plastered, 10 meshes of glass fiber cloth are coated and plastered at the finial layer; the effects of firmness and duration are good, and the service life is up to more than 20 years. Under the condition that the volume is the same, the manufacturing cost of the marsh gas tank in the invention is 400 Yuan, but the manufacturing cost of the present marsh gas tank is 1,000 Yuan; therefore, about 600 Yuan can be saved for each marsh gas tank.

Description

Technical field [0001] The invention relates to a biogas digester, in particular to a low-cost biogas digester using new building materials. It is an improvement on the existing biogas digester structure and belongs to the construction technology of the biogas digester. Background technique [0002] For a long time, the natural fermentation to generate biogas, which has been vigorously promoted in rural areas, has been gradually abandoned because of its high water content, low fermentation rate, long fermentation period, insufficient degradation of the added materials, and low gas production rate. People have developed new competitive biogas digesters. For example, the "Integrated Annular Anaerobic Biogas Digester" issued by the Chinese invention patent application with publication number CN101152967, and the "Integrated Annular Anaerobic Biogas Digester" issued by the Chinese invention patent application with publication number CN1884472. Multi-energy and effective biogas digest...
