In the winter time or rainy season, vaporizer gasification efficiency reduces greatly, and especially in the cold north, the temperature of vaporizer export gas during winter (lower approximately 10 ℃ than ambient temperature) becomes cryogenic natural gas far below 0 ℃.For preventing that the direct Entry Firm pipe network of cryogenic natural gas from causing the facilities such as pipeline valve to produce low-temperature embrittleness, also for preventing that cryogenic natural gas density from producing excessive confession greatly and reporting the accomplishment of a task or termination of a mission, rock gas after gasification needs through water-bath type gas heater, its temperature is raised to 5 ℃ again, and then metering, pressure regulation, adds the smelly pipe network of then sending into.
At present, international and domestic recuperator mainly contains Warm water circulation recuperator and steam water-bath recuperator.But all there is certain defect in these two.The working principle of Warm water circulation recuperator is: cryogenic natural gas is heated after absorbing the heat of warm water by being immersed in stainless-steel pipe in warm water, and the hot water cyclesystem that warm water is comprised of water-heating furnace, hot water pump and elevated tank conventionally provides.This system often there will be due to the too high vaporizer preventing water phenomenon of swelling water tank water level, waste thermal water resource.Due to hot water pump and water-heating furnace noise larger, larger to the noise pollution of environment.In addition, this vaporizer also will be equipped with water-heating furnace and hot water pump.
The working principle of steam water-bath recuperator is: cryogenic natural gas is heated after absorbing the heat of warm water by being immersed in stainless-steel pipe in water, and thermal source is provided by steam, and steam is by being immersed in the coil pipe in water, and coil pipe transfers heat to water again.This mode of heating steam utilization is low, waste resource, and need to be equipped with steam boiler.
