Rotary adsorption system for desulfurization and denitrification of steam injection boiler fuel oil

The utility model discloses a rotary adsorption system for desulfurization and denitrification of steam injection boiler fuel oil. The rotary adsorption system comprises a fuel oil adsorption system and an adsorbent regenerating system, wherein the fuel oil adsorption system comprises an oil tank, a three-way valve, an oil pump, an adsorption part of a rotary adsorption device, a sulfur and nitrogen content detection device, a liquid level detection device and an oil inlet valve; and the adsorbent regenerating system comprises a raw material tank, a waste liquid storage device, a circulating pump, a feed pump, a return liquid pump and a regenerating part of the rotary adsorption device. The rotary adsorption device in the system consists of an adsorption part and a regeneration part, wherein the adsorption part comprises an upper oil storage tank, an adsorption zone and a lower oil storage tank; and the regeneration part comprises an upper raw material box, a regeneration zone and a lower waste liquid tank. The system adopts a rotary structure and combines the adsorption zone and the regeneration zone together to ensure that the size of the system is relatively small and the system can be moved conveniently; and moreover, the system is relatively low in investment cost and operation cost, is convenient to operate, and can be well adapted to oilfield steam injection boilers.
