Insulating composite assembly board methane fermentation tank

Abstract

The invention discloses an insulating composite assembly board methane fermentation tank, which comprises an assembly tank wall body formed by fixedly splicing assembly boards. Stirrups are arranged on the circumference of the assembly tank wall body; joints between the stirrups and the assembly boards are fixed together through bolts, and the joints are sealed by adopting sealing materials; the assembly boards respectively consist of a middle base layer, a covering layer and an insulating layer, wherein the covering layer and the insulating layer are respectively arranged at both sides of the base layer, the base layer is made of carbon steel, and the covering layer is made of stainless steel; the assembly boards are rectangular; bolt holes are arranged at four sides of each assembly board; the stirrups are respectively made of hot galvanizing angle steel; each layer of adjacent stirrups along the peripheral direction of the assembly tank wall body are connected through a stirrup connecting piece; both sides in the length direction of the corresponding assembly board are respectively provided with a row of bolt holes; both sides in the width direction of the corresponding assembly board are respectively provided with two rows of bolt holes in parallel; and the lower end of the assembly tank wall body is fixedly connected with an embedded steel board in a concrete foundation. The insulating composite assembly board methane fermentation tank disclosed by the invention has the advantages that the corrosion is resisted; the installation rate is high; the service life is long; the reusability is high; processes can be reduced; and the construction period is shortened.

Description

technical field [0001] The invention relates to a thermal insulation type composite assembled board biogas fermenter. Background technique [0002] At present, reinforced concrete tanks and steel structure tanks are commonly used in biogas fermentation projects. The construction process of steel mixed tanks is complicated, the cycle is long, the structural design is cumbersome, and the cost is high; while the steel structure welded tanks are welded on site, the construction quality is difficult to guarantee, and it is also anti-corrosion. Poor performance, short service life, and small pool capacity; the limitations of the above two reactors increase the difficulty of biogas project construction and later maintenance, making the construction process of biogas projects complex, prolonging the construction period, and high costs, hindering the development of the biogas industry. [0003] Simplifying the construction process, improving construction efficiency, shortening the co...
