Spliced thermal insulation methane tank

Abstract

The invention discloses a spliced thermal insulation methane tank which is a spherical or cylindrical tank. The tank is formed by splicing an upper tank (2) and a lower tank (3), wherein the upper tank and the lower tank are connected by using a prearranged flange and are adhered; the upper tank is provided with a feed and discharge port, so that feed and discharge are facilitated; the feed and discharge port is firmly connected with a sealing cover by using bolts, so that air-tightness of the tank is guaranteed; the sealing cover is provided with an air nozzle and a pressure relief module (1), so that external gas supply and methane pressure in the tank do not exceed a safety range; and the tank is divided into an inner layer (5), a thermal insulation layer (6) and an outer layer (7). The spliced thermal insulation methane tank has the advantages of simple structure, high thermal insulation performance, high strength, practicability, easiness for disassembly and assembly, science and preciseness, convenience for industrial production, installation and transportation and simplicity in operation and maintenance.

Description

Technical field: [0001] The invention is a spliced ​​thermal insulation biogas tank. The biogas tank is formed by splicing upper and lower tank bodies, and the tank body is composed of an inner layer, an insulating layer and an outer layer. Background technique: [0002] Biogas is a new energy industry strongly supported by the state. Biogas plays a vital role in solving rural daily energy problems and environmental protection issues. The development of rural biogas is a long-term basic national policy of our country. [0003] The generation of biogas requires certain environmental conditions. Biogas generation needs to be in a certain temperature, airtight, anaerobic, humid, and moderate pH environment, especially temperature is the key condition for biogas generation. At present, the vast northern region and some southern regions in China are cold in winter, and dripping water turns into ice. In many regions, biogas tanks cannot produce gas in winter, or even freeze. This...

AI Technical Summary

Problems solved by technology

At present, the vast northern region and some southern regions in China are cold in winter, and dripping water turns into ice. In many areas, biogas tanks cannot produce gas in winter, or even freeze

This has caused great difficulties for the popularization and use of biogas

In addition, the industrial production, installation and transportation of biogas digesters have always been difficult problems
