The utility model discloses a
yellow phosphorus furnace gas all-time automatic extraction
system which comprises a
cooling tower, a first
exhaust pipe and a second
exhaust pipe are arranged in the middle of the upper end of the
cooling tower and at the upper end of one side of the
cooling tower respectively, and the other end of the first
exhaust pipe is connected with a buffer storage
assembly. The other end of the second exhaust
pipe is connected with the middle of the top of the second purification box through a three-way connector, a second conveying
pipe, a
frequency conversion fan and a third conveying
pipe. The lower end of one side of the second purification box is connected with the lower end of one side of the
gas cabinet through a communicating pipe. According to the
yellow phosphorus furnace gas full-time-period automatic extraction
system, the first variable-frequency suction pump, the quantitative suction pump, the variable-frequency fan and the second variable-frequency suction pump are matched for use, so that the
smoke suction and conveying speed is conveniently changed according to the pressure value of
smoke generated by
combustion in the furnace, the pressure in the furnace is conveniently and automatically adjusted, the use safety is improved, and the practicability is high. And secondly, by adjusting the
flue gas conveying capacity, the furnace gas is continuously conveyed to the subsequent
recovery treatment process, and the furnace gas is prevented from being directly discharged to a
torch to be combusted.
