Embodiment Construction
[0017] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. However, it should be understood that the accompanying drawings are provided only for better understanding of the present invention, and they should not be construed as limiting the present invention.
[0018] Such as figure 1 As shown, the present invention includes a seawater supply system 1 , a compressed air system 2 , a gas-liquid premixer 3 , a gas-liquid distributor 7 and a gas-liquid equalizer 11 . Wherein, the seawater supply system 1 communicates with an inlet of the gas-liquid premixer 3 through the seawater supply pipeline, the compressed air system 2 communicates with the other inlet of the gas-liquid premixer 3 through the air supply pipeline, and the gas-liquid premixer The outlet of 3 communicates with the inlet of the gas-liquid equalizer 11 arranged in the straight flue gas exhaust pipe 8 through the gas-liquid mixed fluid supply pipe...

The invention relates to a combined air-liquid smoke dust-removing forced guiding device. The combined air-liquid smoke dust-removing forced guiding device comprises an air-liquid premixing device installed outside a smoke-discharging straight pipe, a seawater supplying system communicated with one inlet of the air-liquid premixing device through a seawater supplying pipe and a seawater regulating valve, a compressed air system communicated with the other inlet of the air-liquid premixing device through an air supplying pipe and an air regulating valve, an air-liquid equally-distributing device communicated with an outlet of the air-liquid premixing device through an air-liquid mixing fluid supplying pipe and an air-liquid mixing fluid regulating valve and an air-liquid distributor communicated with an outlet of the air-liquid equally-distributing device through a plurality of air-liquid distributed delivering pipes. The air-liquid equally-distributing device and the air-liquid distributor are both arranged inside the smoke-discharging straight pipe, and the outlet of the air-liquid distributor faces an outlet of a smoke pipe. By means of the combined air-liquid smoke dust-removing forced guiding device, the content of dust in smoke can be decreased, the discharging effect of the smoke can be improved, the structure is simple, operation is convenient, and application cost is low.
Description
technical field [0001] The invention relates to a flue gas treatment device, in particular to a composite gas-liquid mixed fluid forced diversion used for flue gas dust removal and flue gas emission control of crude oil generating units on offshore platforms or FPSO (floating oil storage and offloading units). device. Background technique [0002] At present, high-power crude oil generator sets are often used in offshore oilfield development to provide the electricity needed for oilfield production and development. Especially for oil fields with insufficient associated gas, crude oil generator sets are being used more and more on offshore platforms or FPSOs as an economical self-generation solution. Offshore crude oil generating units usually use crude oil produced by the oilfield as fuel. Due to the influence of various factors such as unit load rate, fuel water content and fuel quality, the dust content in the flue gas emitted by crude oil generating units is often high. ...
