Abstract

The invention discloses an integral positive / negative pressure protector composed of an outer cylinder, an inner cylinder, a pressure balancing pipe, an evacuating pipe, a liquidometer, and sealed liquid. The outer cylinder and the inner cylinder are connected through a flange. The evacuating pipe communicates with the inner cylinder. The pressure balancing pipe communicates with the outer cylinder. The sealed liquid is non-compressible. The sealed liquid is Newton fluid with a boiling point no lower than 80 DEG C and a melting point no higher than -40 DEG C. According to the invention, positive and negative pressure protecting functions are integrated, such that defects of traditional technologies of increased investment, tedious management and large land occupation caused by independent positive and negative pressure protectors are avoided. The protector provided by the invention is advantaged in stable operation. The protector can provide effective and reliable protections for containers.

Description

technical field [0001] The invention relates to a positive and negative pressure protection device for a large storage tank, in particular to a positive and negative pressure protection device for an anaerobic fermentation reactor in a biogas project. Background technique [0002] In recent years, the development of biogas production technology by anaerobic fermentation of livestock and poultry manure has provided technical support for effectively solving the pollution of livestock and poultry breeding and developing clean energy. During the normal operation of the anaerobic fermentation reactor, the pressure in the reactor often fluctuates due to the influence of the incoming and outgoing materials, changes in the external temperature, and fluctuations in the gas system. In order to prevent the tank from being unstable or cracked due to pressure fluctuations, a positive pressure must be set. and negative pressure protection device. There are several types of positive press...
