Methane tank positive-pressure protector

Abstract

The invention discloses a methane tank positive-pressure protector. The protector comprises a water channel (1), a buffer pocket (2) and an air inlet pipe (3), wherein a plurality of water drainage pipes (11) are arranged on the side wall of the water channel (1) in the vertical direction; valves are arranged on the water drainage pipes (11); the buffer pocket (2) is fixed in the water channel (1); the side wall and the top of the buffer pocket (2) are sealed; one or more exhaust vents (21) are fixed at the bottom of the buffer pocket (2); the exhaust vents (21) are located at the inner lower part of the water channel (1); the air inlet pipe (3) extends into the buffer pocket (2); the air outlet area of the air inlet pipe (3) is smaller than the total area of the exhaust vents (21). The methane tank positive-pressure protector is simple in structure, low in manufacturing cost, and convenient to use, can effectively stabilize the biogas pressure and avoid unsafe factors due to overlarge pressure, and is suitable for rural popularization and application.

Description

technical field [0001] The invention belongs to the technical field of biogas pond construction, and in particular relates to a positive pressure protection device for biogas ponds with simple structure and low price. Background technique [0002] With the development of our country's economy and social progress, the life of urban residents has been further improved, but there are still many problems in the life of rural residents. In order to build a well-off society in an all-round way, it is very necessary to build a new socialist countryside. This requires the development of rural ecological agricultural production methods to improve the rural environment; among them, the comprehensive utilization of biogas digesters is an important way to change the rural environment. The construction of a biogas digester can be used for about 20 years. Comprehensive utilization of biogas digesters can not only save energy, improve and protect the environment, but also save chemical fe...

AI Technical Summary

Problems solved by technology

However, the process of biogas production is affected by many factors such as ambient temperature, pH, and feed concentration. When in use, the pressure of the supplied biogas is unstable, and the combustion flame fluctuates greatly, making it difficult to operate; will have security implications

Some industrial air pressure valves currently on the market can be used in biogas digesters, but the pressure of the biogas is low, and general air pressure valves are not practical, and the humidity of the biogas is high and corrosive, so the air pressure valves are prone to corrosion and become invalid; at the same time, the air pressure valves relatively high price
