Abstract

A flue gas conveyer for two-stage brine purification comprises a flue gas compressor, at least one control valve and a safety valve; the flue gas compressor is communicated with a flue gas conveying pipe, and compressed flue gas is conveyed to the bottom of a brine purification reacting barrel; the flue gas conveying pipe includes a main flue gas conveying pipe and at least one auxiliary flue gas conveying pipe, and each auxiliary flue gas conveying pipe is provided with a control valve; one end of the safety valve is communicated with the main flue gas conveying pipe, and the other end thereof is communicated with air. The invention also discloses a method of using the flue gas conveyer for two-stage brine purification. The flue gas conveyer is simple in structure and low in manufacture cost and is effective in preventing brine in the brine purification reacting barrel from flowing back under siphoning action, thereby prolonging the life of the flue gas compressor.

Description

technical field [0001] The invention relates to a secondary brine purification device, in particular to a flue gas conveying device for secondary brine purification and a use method thereof. Background technique [0002] Adding flue gas in the secondary reaction of brine purification is conveyed by the flue gas compressor; , so that the brine in the reaction barrel flows back into the flue gas compressor with the pipeline under the action of siphon, which has a major impact on the equipment, affects the normal use of the flue gas compressor, and reduces its service life. There is an urgent need to provide a flue gas conveying device for secondary brine purification with stable flue gas conveying pressure, which can avoid siphon phenomenon and prevent pipe bursting. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the deficiencies of the prior art, to provide a flue gas delivery device for secondary brine purifi...
