Abstract

The invention relates to the technical field of water treatment, and discloses an industrial triple-effect salt-containing wastewater evaporating crystallizer and a pressure balancing method. The industrial triple-effect salt-containing wastewater evaporating crystallizer comprises a pipeline, evaporators are fixedly connected to the two sides of the pipeline respectively, an outer pipe wall is fixedly connected to the exterior of the pipeline, and a one-way pressure relief valve is movably connected to one side of the outer pipe wall; a movable plate is movably connected to one side of the one-way pressure relief valve, a partition plate I is fixedly connected to the interior of the outer pipe wall, and a one-way pressure valve I is fixedly connected to the top end of the partition plate I. Through cooperation of the two-way pressure valve and the through hole in the middle of the pipeline, when the equipment is normally used, steam storage at the position with too high steam pressure and steam supply at the position with too low pressure are conducted outside the whole pipeline, so that the pressure of the whole pipeline is balanced, steam supply is uniform, the outer pipe wall can provide a heat preservation layer for the outer side of the pipeline, and the problem that the internal pressure of the pipeline is unbalanced due to the environment temperature is avoided.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an industrial three-effect saline wastewater evaporation crystallizer and a pressure balancing method. Background technique [0002] The three-effect salt-containing wastewater evaporation crystallizer performs evaporation treatment on the feed liquid under vacuum negative pressure conditions. Since the boiling point of the feed liquid decreases under vacuum negative pressure conditions, and the generated water vapor will be quickly condensed or discharged, the evaporation speed is faster. , when the equipment is running, the secondary steam generated by the first effect can be used as the heating medium of the second effect heater through the action of the external circulation pump, and the secondary steam of the second effect can be used as the heating medium of the third effect heater, and the heat energy is obtained Fully utilized, thus saving boiler steam energy cons...
