1. Technical field

The utility model relates to the technical field of fermenting tanks or fermenting containers for bioenergy to obtain biogas, in particular to dry and wet fermentation biogas tanks assembled from multi-layer thermal insulation prefabricated parts.

2. Background technology

Existing rural biogas fermentation tanks, whether they are dry fermentation or liquid fermentation, mostly use underground digging, use bricks to form spherical, cylindrical or square fermentation tanks, and plaster the inner walls with concrete. Although the water-tight and air-tight pressure-bearing pool wall is simple and convenient, the insulation effect is poor, especially in winter when the temperature is low, so that the gas production capacity is greatly reduced. Aiming at this defect, the utility model designs a multi-layer insulation prefabricated part The assembled dry and wet fermentation tanks can not only be used for the liquid fermentation commonly used in the south, but also suitable for the dry material fermentation process used in the north. It adopts industrialized mass production, and assembles the components after they arrive at the destination, which is convenient for transportation. The requirements are not high, and the pond can be built regardless of sandy soil or gravel. At the same time, it is convenient and fast, and the construction period is shortened, which is 10-15 days shorter than that of the integral casting biogas digester.

The purpose of this utility model is to provide a dry and wet fermentation biogas tank assembled from multi-layer thermal insulation prefabricated parts. The height of the upper half is 2/5 of the overall height, the height of the lower half is 3/5 of the overall height, the upper half is composed of three, four, six or eight pieces, and the lower half is also composed of three, four , Six or eight pieces are combined, and each prefabricated block in the upper and lower halves is provided with an outwardly protruding flange, and each corresponding flange is provided with an axial hole. The two prefabricated blocks corresponding to the upper and lower parts are connected by screws, and radial holes and radial locking screws are also provided between the two corresponding upper and lower blocks. A layer of adhesive to make it firmly bonded to water and air tightness. Each prefabricated component is composed of three or five layers. The three-layer structure is: the inner layer is made of high-strength concrete, and the middle layer is made of thermal insulation and lightweight materials. The outer layer is made of concrete, and the five-layer structure is based on the first three layers, adding a mixture of slag and thermal insulation materials as filling materials, and the outer layer is composed of five layers of ordinary concrete as the protective layer. With a three-layer structure, the upper and lower corresponding parts should be a three-layer structure; with a five-layer structure, the upper and lower corresponding parts should be prefabricated parts with a five-layer structure, a dry material fermentation tank, and the top of the upper half of the tank is equipped with a feed The mouth is sealed by a sealing cap. The liquid material fermentation tank has a feed inlet under the sealing cover, and a slag outlet is provided at a position lower than the feed inlet on the other side of the tank, and the opening tops of the two ports must be higher than the sealing cover.

The beneficial effect of adopting this technical solution: it can be produced in industrialized batches, it is convenient for transportation and assembly, it is not strict on the site, it can shorten the construction period, it is suitable for both dry and wet fermentation methods, it has good heat preservation performance, and it can produce gas continuously in winter The utilization of bio-energy and the popularization and application of biogas have a great promotion effect, and the installation is convenient and the service life is long.
