Technical Field

The utility model relates to the technical field of chemical wastewater treatment, in particular to a steam crystallization separator for inhibiting liquid foam.

Background

The manufacturing of chemical bulk drugs is the pharmaceutical sub-industry with the largest pollution load, and the wastewater is the largest contributor to the pollutant load, so the problem of wastewater pollution generated in the production of chemical bulk drugs is urgently needed to be taken into consideration. Generally, zero emission is the main direction and target of the current enterprise wastewater, wherein an evaporative crystallization separator is required to be used, but the height of the traditional evaporative crystallization separator is generally higher. Install in the space that faces highly restricted, perhaps the timing is designed under the not big condition of throughput demand, often can reduce the height of separator, but inside waste liquid can produce the liquid foam in continuous evaporation process, and the liquid foam upwards piles up along the section of thick bamboo wall, because highly not enough, the liquid foam gets into the steam discharge pipeline very easily and causes the problem of blockking up or waste liquid discharge incomprehensible before disappearing naturally, and present defoaming mechanism efficiency is unsatisfactory, still discharges along with steam easily.

SUMMERY OF THE UTILITY MODEL
