The utility model discloses an efficient deacidification device for liquefied natural gas, which comprises a deacidification tower, the top of the deacidification tower is communicated with an amine liquid input pipe and a gas output pipe, a spray head is communicated with the amine liquid input pipe in the deacidification tower, the bottom of the deacidification tower is provided with a natural gas input pipe and a circulating pipe, and the circulating pipe is provided with a pump body. The other end of the circulating pipe is connected with a gas-liquid mixing jet device, the output end of the gas-liquid mixing jet device is communicated with the natural gas input pipe, and the gas input end of the gas-liquid mixing jet device is communicated with a gas conveying pipe used for inputting untreated natural gas. The headed amine liquid is collected at the bottom in the deacidification tower and is conveyed into the gas-liquid mixing jet device by the pump body to be mixed with untreated natural gas, so that th
