The invention provides a liquid cargo heating system. The liquid cargo heating system is provided with a gas phase output port for conveying gas cargo outwards and comprises a seawater heater, an ethylene glycol heater and a storage tank. The seawater heater is provided with a seawater inlet, a seawater outlet, a first liquid cargo port and a first gas cargo port. The ethylene glycol heater is provided with an ethylene glycol inlet, an ethylene glycol outlet, a second liquid cargo port and a second gas cargo port. The storage tank is used for storing liquid goods, and a third liquid goods port and a third gas goods port are formed in the top of the storage tank. The third liquid cargo port is selectively communicated with the first liquid cargo port or the second liquid cargo port, and the third gas cargo port is correspondingly and selectively communicated with the first gas cargo port or the second gas cargo port, so that the seawater heater or the ethylene glycol heater is used for heating the liquid cargo into gas cargo, and the gas cargo returns to the storage tank or is output through the gas phase output port. At the moment, the ethylene glycol heater is added to heat the liquid cargo, and the problem that the liquid cargo cannot be heated in a low-temperature seawater sea area is solved.

    本申请提供一种液货加热系统。该液货加热系统具有向外输送气货的气相输出口,其包括海水加热器、乙二醇加热器和储罐。海水加热器上设置有海水入口、海水出口、第一液货端口和第一气货端口。乙二醇加热器上设置有乙二醇入口、乙二醇出口、第二液货端口和第二气货端口。储罐用以储存液货,其顶部设置有第三液货端口和第三气货端口。第三液货端口选择性地与第一液货端口或第二液货端口连通,第三气货端口对应地选择性地与第一气货端口或第二气货端口连通,以利用海水加热器或乙二醇加热器将液货加热为气货,气货返回储罐或经气相输出口输出。此时,通过增加乙二醇加热器加热液货,解决在低温海水海域无法对液货加热的问题。
