1. Product Description
(1) The positive and negative pressure protector is mainly used to eliminate excessive pressure or negative pressure in equipment under abnormal working conditions to ensure safe operation of the equipment.
(2) If condensed water is generated, it will automatically drain. When the pressure exceeds 2000Pa, it will automatically exhaust. When it is lower than 300Pa, it will automatically adjust the suction to ensure that the equipment will not have negative pressure and ensure safe operation of the equipment.
(3) The equipment is equipped with special antifreeze to solve the problem of normal use in cold areas
2 Working Principle
(1)There is a certain depth of water seal inside the positive pressure protector to prevent biogas leakage and relieve pressure.
(2)When the anaerobic tank is fed and stirred, the gas production suddenly increases and the pressure increases. The water level in the central pipe drops and biogas escapes from the lower end of the central pipe and is discharged into the atmosphere through the chimney on the side wall.
(3)There will also be a water seal inside the negative pressure protector. When the pressure inside the tank is within the normal range, the pressure inside the tank will press against the sleeve, then air cannot enter. When the anaerobic tank discharges liquid and mud, it will cause the liquid level inside the tank to rapidly drop, forming negative pressure. The external pressure is greater than the internal pressure and the float rises. After the float leaves the water surface, air enters and the internal and external pressure is balanced.
