Abstract

The invention discloses an overpressure protector for a methane double-membrane gas storage cabinet. The overpressure protector for the methane double-membrane gas storage cabinet comprises a shell. Amain pressure relief hole and an auxiliary pressure relief hole are formed in the shell, and the auxiliary pressure relief hole and the main pressure relief hole communicate with each other. A pressure relief valve is installed in the main pressure relief hole, an outlet of the auxiliary pressure relief hole is formed in the outlet side of the pressure relief valve, and a pressure adjusting valveis installed in the auxiliary pressure relief hole. A pressure sensor is installed in an inlet of the shell and transmits pressure signals to a pressure controller, and the pressure controller controls the opening degree of the pressure adjusting valve. The overpressure protector for the methane double-membrane gas storage cabinet can overcome the defects in the prior art and reduces the disturbance of the internal pressure of a cabinet body.

Description

technical field [0001] The invention relates to a biogas storage safety device, in particular to an overpressure protector for a biogas double-membrane gas storage cabinet. Background technique [0002] The double-membrane gas holder is a biogas storage device widely used in the biogas industry. Due to the limitation of the tensile strength of the membrane material of the gas holder, the double-membrane gas holder can only work at a lower pressure state. In order to prevent the overpressure of biogas produced by anaerobic fermentation from damaging the gas holder, an overpressure protection device must be installed on the gas holder. The existing overpressure protection device greatly disturbs the pressure inside the cabinet when it operates, which affects the normal transportation of biogas. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an overpressure protector for a biogas double-membrane gas storage cabin...
