Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
The embodiment of the utility model provides an electric heating system suitable for ocean LNG discharges storage tank combines fig. 1 to fig. 5 to show, main control unit and 4 sub-heating systems, and main control unit can every sub-heating system of independent control work alone, can realize local control and remote control's switching with heating system through main control unit. When the main control unit is in a local control mode, the start and stop of the system are completely controlled by the operation of a local control panel, and field personnel can carry out independent manual start and stop operation on each sub-heating system. When the control system is in the remote control mode, the heating panel 1 is fully operational controlled by the sub-heating system. In addition, a remote ESD function, as well as a local ESD button, is added for a hard stop shutdown of the entire heating system.
The sub-heating system comprises a control sub-unit and 4 heating units, each heating unit is installed in a heating area, each heating unit is provided with a plurality of heating plates 1 and 1 temperature sensor 2, the heating plates 1 are installed at the bottom of the storage tank, the temperature sensors are installed in the middle of the heating plates 1, each heating plate 1 can work independently under the control of the sub-heating system, and each sub-heating system can adjust the heating power and the heating time of the heating plates 1 according to the temperature fed back by the temperature sensors 2 through the control sub-unit.
