Regenerated gas method and system for wastewater pond aeration

Abstract

The invention relates to a regenerated gas method and a regenerated gas system for wastewater pond aeration. The regenerated gas method comprises the following steps of: collecting regenerated gas of tepid drying machines in a centralized mode, discharging discontinuously and emptying by using a silencer; stabilizing pressure, namely collecting the regenerated gas of the tepid drying machines into a gas storage tank in the centralized mode and stabilizing the pressure of a compressed air pipe network; dewatering, namely arranging an automatic drain valve at the bottom of the gas storage tank and arranging an automatic drain valve on the raised part of a pipeline so as to further remove water in the pipeline; and controlling in the centralized mode, namely arranging a thermal resistor, a pressure transmitter and a flow meter on a regenerated gas main pipe, and monitoring the pressure, the temperature and the flow rate of the regenerated gas on site in real time by using a human machineinterface (HMI) of a work station. The wastewater stations of the system are connected with the gas storage tank respectively, the gas storage tank passes through a gas collecting main pipe and is connected with the tepid drying machines of air compression stations by collecting pipes respectively, the tepid drying machines are connected with one regenerated gas pipeline respectively, and the gasstorage tank is connected with the automatic drain valve. On the premise of effectively meeting the requirement of the wastewater pond aeration, the regenerated gas of the tepid drying machines is effectively used, and the method and the system have remarkable energy saving effects.

Description

technical field [0001] The invention belongs to the field of environmental protection and energy saving, and in particular relates to a novel regeneration gas method and system for aeration of waste water ponds. Background technique [0002] At present, the aeration of wastewater tanks mostly adopts blower or high-quality compressed air after drying treatment. Since the pressure of compressed air required for aeration of wastewater tanks is about 3 bar, there is no requirement for water content. Due to the limited number of centrifugal air compressors in the air compressor station, the use of compressed air in other newly added projects has been increasing. The treated high-quality compressed air (pressure about 7bar) is used for wastewater pool exposure after decompression. Such methods will cause waste of energy. [0003] Aiming at the uneconomical situation that compressed air for instrumentation is used for the aeration of wastewater tanks, a simple, practical, economic...
