The utility model provides a technical scheme that its technical problem adopted is: a liquid discharge pipeline system of a gas-liquid separation tank applied to waste alkali liquid treatment comprises the gas-liquid separation tank, a liquid discharge pipeline and a steam backwashing pipeline; the bottom of the gas-liquid separation tank is connected with a liquid discharge pipe, the liquid discharge pipe is connected with a tee joint, the gas-liquid separation tank is respectively connected with a liquid discharge pipeline and a steam backwashing pipeline through the tee joint, and a pilot shower valve A, a pilot shower valve B, a liquid level control valve and a pilot shower valve C are sequentially arranged on the liquid discharge pipeline; the tail end of the liquid discharge pipeline is connected with a neutralized brine pipeline; the upper end of the gas-liquid separation tank is connected with a tail gas treatment system pipeline, and one side of the gas-liquid separation tank is connected with an oxidation tower tail gas pipeline.
Furthermore, a steam control valve is arranged between the steam back-flushing pipeline and the tee joint;
further, a tail gas outlet valve is arranged between the gas-liquid separation tank and a tail gas treatment system pipeline;
further, a tail gas inlet valve is arranged between the gas-liquid separation tank and a tail gas pipeline of the oxidation tower;
compared with the prior art, the utility model beneficial effect who has is:
the utility model provides a be applied to waste alkali liquid treatment's gas-liquid separation jar drainage pipe-line system increases the airtight pipeline that steam back flush pipeline and drainage pipeline and neutralization brine pipe connection constitute, solves flowing back jam and flowing back problem of taking flavor.
The utility model provides a be applied to gas-liquid separation jar fluid-discharge line system that waste lye handled, only need can accomplish the trouble fast and solve when the operating personnel on duty after the flowing back blocking fault appears, no longer need the maintenance personal to intervene the maintenance and handle. The flowing direction of the liquid drainage can be realized only by switching related valves, the operation is convenient and fast, other tools and auxiliary facilities are not needed, and the problems of operation faults and environmental protection are solved.
