Integrated gas-water separator protector

Abstract

The invention relates to a positive-negative pressure protecting and gas-water separating device of an anaerobic fermentation reactor in a biogas project, in particular to an integrated gas-water separation protector. The integrated gas-water separation protector is characterized in that the lower portion of a cylinder is communicated with an anaerobic fermentation tank, the upper portion of the cylinder is connected to a cover plate with an exhaust pipe, and the lower end of the exhaust pipe is located in the cylinder and communicated with a water seal tank; a condensing bottom plate is arranged in the cylinder, a central hole is formed in the middle of the condensing bottom plate, a gap allowing biogas with vapor to pass is formed between the condensing bottom plate and the water seal tank, and baffling cylinders capable of prolonging the retention time of the biogas with the vapor are respectively arranged on the upper surface of the condensing bottom plate and on the lower surface of the cover plate; the exhaust pipe and the water seal tank are communicated with the atmosphere. The integrated gas-water separating protector has the advantages that a positive-negative pressure protecting function and a gas condensing function are integrated, anaerobic fermentation reaction is prevented from being affected by pressure changes in the tank, and the aerobic fermentation can be performed normally; meanwhile, a pipeline is prevented from being frozen off due to vapor condensing and icing of the biogas with the vapor in a cold region, and maintenance cost is lowered.

Description

technical field [0001] The invention relates to a positive and negative pressure protection and a gas-water separation device for a pressurized oxygen fermentation reactor in a biogas project, in particular to an integrated gas-water separation protector. Background technique [0002] In recent years, anaerobic fermentation biogas production technology has been extensively studied by scholars at home and abroad because it can recycle energy and effectively solve pollution problems such as livestock and poultry breeding. 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. The biogas produced by fermentation contains water v...
