Abstract

The invention relates to an automatic exhaust device of a biogas tank, belonging to the technical field of biogas production and manufacture. The automatic exhaust device of the biogas tank comprisesan exhaust pipe, an explosion-proof electromagnetic valve, a pressure sensor, a processing and control unit and a water return elbow pipe, wherein the explosion-proof electromagnetic valve is installed on the exhaust pipe; a U-shaped drain pipe is connected with the exhaust pipe at the left side of the explosion-proof electromagnetic valve; the front end of the water return elbow pipe is connectedwith the exhaust pipe between the explosion-proof electromagnetic valve and the U-shaped drain pipe, and the rear end of the water return elbow pipe is connected with the tail end of the right side of the exhaust pipe; the pressure sensor is connected with a signal input end of the processing and control unit, and a control end of the processing and control unit is connected with the explosion-proof electromagnetic valve. During installation, the left port of the exhaust pipe is installed on the top of the inside of the biogas tank, and water is injected into the water return elbow pipe; whenthe gas pressure is greater than a set value, the pressure sensor receives a pressure signal and sends same to the processing and control unit; the processing and control unit controls the explosion-proof electromagnetic valve to be opened, and the gas is discharged through the right port of the exhaust pipe. The device provided by the invention can prevent accidents caused by excessive pressurein the biogas tank, and enables the biogas tank to be high in gas generation rate, safe and stable.

Description

technical field [0001] The invention belongs to the technical field of biogas production and manufacture, and relates to an exhaust device. Background technique [0002] The biogas tank is mainly made of a closed tank, which can process organic waste, straw, and manure to generate biogas and fertilizer. If the gas is produced in a large amount and is not used in time, the pressure in the tank will be too high, which may damage the biogas tank or even burst. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic exhaust device for a biogas tank, which can discharge the biogas exceeding the standard pressure. [0004] The solution to the technical problem of the present invention mainly includes an exhaust pipe, an explosion-proof solenoid valve, a pressure sensor, a processing and controller, and a reverse water elbow. Connect a U-shaped drain pipe. The front end of the anti-water elbow is connected to the...
