State the scene behaviour that control level-one cooling fan, second level cooling fan and three-level cooling fan are separately provided on workbench
Make column.
The present invention is further arranged to: be provided on the heat exchanger tube for BOG process gas disengaging process gas into
Gas flange port and process gas outlet flange port.
Beneficial effects of the present invention:
1, the efficient cooling of three-level BOG process high-temperature gas can be achieved；It can be opened by three groups of cooling fans and shutter
Angle control air quantity is opened, realizes that 135 DEG C of BOG process gas of every grade of highest are cooled to 40 DEG C；Securely and reliably, it is ensured that BOG pressure
The operation of contracting captain's cyclic stationary.
2, three groups of fan motors can realize long-range control by DCS and SIS, can individually open, part is opened, is all opened
The function of opening and all close, then cooperate temperature measurement on-line element, meet and opened in some or all of most hot moon cooling fan,
The independent unlatching of most cold moon cooling fan is all closed, and cooling control is flexibly carried out according to the variation of environment and operating condition.
3, large-sized wind cooling device is equipped with on-line temperature monitoring, when environment temperature >=30 DEG C, to guarantee cooler outlet temperature
40 DEG C, three groups of fan motors are all turned on；As 30 DEG C of 0 DEG C≤environment temperature <, automatically switches to two groups of fans and open；If environment
It 0 DEG C of temperature <, automatically switches to one group of fan and individually opens；Realize electromechanical integration and energy-saving and emission-reduction.It can also control manually simultaneously
Make three groups of fan motors, flexible and convenient operation.
