LNG gasification pressure regulating skid, including frame, LNG storage tank, air-temperature gasifier, water-bath gasifier, PLC control system and automatic adjustment device, the LNG storage tank, air-temperature gasifier, water-bath gasifier The air heater, the PLC control system and the automatic adjustment device are arranged in the frame, the LNG storage tank is installed in the frame through the support assembly, and the air-temperature gasifier is installed in the support assembly at the lower part of the LNG storage tank Between, the LNG storage tank, the automatic adjustment device, the air temperature type vaporizer, and the water bath type vaporizer are sequentially connected through pipelines, and the outlet of the air temperature type vaporizer is connected to the gas phase inlet of the LNG storage tank and the water bath simultaneously. The inlet of the vaporizer is connected, and the automatic adjustment device controls the pressure of the LNG storage tank by controlling the volume of gas entering the LNG storage tank from the air-temperature vaporizer.
1. The air-temperature vaporizer is fixed between the support components at the bottom of the LNG storage tank to reduce the floor space. The outlet of the air-temperature vaporizer is connected to the gas phase inlet of the LNG storage tank and the inlet of the water bath vaporizer at the same time. It has dual functions of pressure, temperature increase and gasification, and the equipment utilization rate is high.
2. When the pressure of the storage tank is higher than the set value, the gas in the gas phase space of the storage tank is preferentially used by the automatic adjustment device to reduce the gas emission. When the pressure of the storage tank is too low, the automatic adjustment device automatically pressurizes the storage tank to facilitate the normal operation of the equipment.
3. The new model combines the equipment into an integrated type through a reasonable layout, shortens the medium conveying distance and reduces the low temperature liquid gasification rate.
4. The storage tank of this equipment adopts a differential pressure liquid level gauge, which can monitor the height of the liquid level in the storage tank in real time to prevent the liquid level from being too high and the liquid overflowing. When the liquid level is too low, it will automatically alarm and fill the liquid in time.
5. The device has a built-in gas probe device. When gas leakage occurs, it will automatically send out an alarm signal and automatically cut off the gas source in an emergency, which is conducive to the operation of the device.
