The invention relates to pharmaceutical wastewater evaporating equipment which comprises a heat exchanger, a heating separator, a heater, a crystallization separator, a valve, a circulating one-way valve and a backflow one-way valve. An inflow of the pharmaceutical wastewater evaporating equipment is connected to a water inlet of the heating separator through the heat exchanger, and an outflow of the pharmaceutical wastewater evaporating equipment is connected to a steam port of the heating separator through the heat exchanger. The discharge port of the heating separator is successively connected to the valve, the crystallization separator, a backflow pump, the backflow one-way valve and the water inlet of the heating separator through a pipeline. The water outlet of the separator is successively connected to a circulating pump, the circulating one-way valve and the water inlet of the heating separator through a pipeline. Heat is circulated to react in the equipment by means of self circulation of wastewater of the heating separator, circulation between the crystallization separator and the heating separator and heat exchange of steam and inflow in the heat exchanger, so that a purpose of making full use of heat is achieved, the cost in the pharmaceutical wastewater treatment process is lowered, the energy sources are saved, and the pharmaceutical wastewater is fully treated by means of circulation of the wastewater.
Description
technical field [0001] The invention relates to the field of waste water treatment equipment, in particular to a pharmaceutical waste water evaporation equipment. Background technique [0002] Pharmaceutical industry wastewater mainly includes four categories: antibiotic production wastewater, synthetic drug production wastewater, Chinese patent medicine production wastewater, and washing water and flushing wastewater in the production process of various preparations. The wastewater is characterized by complex components, high organic content, high toxicity, deep color and high salt content, especially poor biochemical properties, and intermittent discharge, which is difficult to treat industrial wastewater. With the development of my country's pharmaceutical industry, pharmaceutical wastewater has gradually become one of the important sources of pollution. How to deal with this type of wastewater is a difficult problem in environmental protection today. Contents of the in...
