The invention discloses a marine heavy
fuel oil purifying and
heating system. The marine heavy
fuel oil purifying and
heating system comprises a heavy
fuel oil hot-oil circulating and
heating system and a heavy fuel oil purifying
system connected with the heavy fuel oil hot-oil circulating and heating
system through a pipeline; conduction oil circulates in the heavy fuel oil hot-oil circulating and heating
system, and the heavy fuel oil hot-oil circulating and heating system comprises a boiler, a heavy fuel oil
sediment tank, a heavy fuel oil daily tank, an oil-gas separator and a hot oil
circulating pump, wherein a loop is formed by the boiler, the heavy fuel oil
sediment tank, the heavy fuel oil daily tank, the oil-gas separator and the hot oil
circulating pump; the heavy fuel oil purifying system comprises an oil separator heater and an oil separator, the oil separator heater is connected with the heavy fuel oil
sediment tank through a pipeline, the input end of the oil separator is connected with the oil separator heater, and the output end of the oil separator is connected to the heavy fuel oil daily tank through a pipeline. Heavy fuel oil is heated to improve flowability and ensure transportation of the heavy fuel oil, and the heavy fuel oil is purified, so that working efficiency of a
diesel engine set is improved, and service life of the
diesel engine set is prolonged.
