Description
Technical field
The utility model belongs to the process field of water, waste water or sewage, relates to the chemical plant wastewater treatment unit of a kind of distillation or method of evaporating.
Background technology
At present, in existing chemical plant wastewater, be all much be rich in nitrogen, phosphorus, inorganic salt and other material, existing treatment process neutralizes by adding chemical substance, but cost can be caused so higher, small chemical factory is difficult to the situation of bearing.Therefore run into chemical plant regulation contrary to law sometimes and privately rank undressed waste water, the consequence of eutrophication after these waste water enter public water source, can be caused.
MVR is the abbreviation of mechanical vapor recompression technology (Mechanical Vapor Re-compression), is the energy re-using the secondary steam that it self produces, thus reduces a power-saving technology of energy demand to external world.Function of mechanical steam recompression is a kind of evaporation technology, it is the secondary steam recompression mechanically vaporizer produced, its pressure, temperature is made to increase, in improving after energy, return former vaporizer again, replace raw steam to use as thermal source, the latent heat in secondary steam is fully used, energy-conservation object can be reached.Mechanical vapor recompression technology is widely used in the industries such as chemical industry, pharmacy, food, papermaking, sewage disposal, sea water desaltination.
Utility model content
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and the utility model provides a kind of chemical plant wastewater treatment unit, easy to operate, and energy-conserving and environment-protective are practical.
For achieving the above object, basis is practical is newly achieved through the following technical solutions:
Chemical plant wastewater treatment unit, comprise interchanger and vaporizer, vaporizer connects steam trap and discharging pump successively by pipeline, vaporizer and come to be connected with between the mouth of a river interchanger, transferpump and water inflow filter, vapour compressor is provided with between the steam-in of vaporizer and steam trap, the material liquid outlet end of vaporizer is provided with container for storing liquid, container for storing liquid is connected with foam killer storage tank by pipeline, be provided with control valve between container for storing liquid and foam killer storage tank, liquid outlet and the interchanger feed liquid port place of container for storing liquid are provided with recycle pump.
Vaporizer is provided with condensation-water drain, is connected with interchanger.
Steam trap be provided with venting port.
When the utility model uses, first waste water enters water inflow filter, and removal can affect the insoluble suspended substance that follow-up equipment normally runs.After filtering, water outlet enters interchanger, exchanges the waste heat of steam condensate, enters recycle pump subsequently, mix with the waste water in recycle pump, enter in vaporizer with pipeline; Water is condensed into after steam heat-exchanging in vaporizer, enter cold heat exchanger and discharge vaporizer, remaining uncooled steam and other noncondensable gases are if the oxygen, carbonic acid gas, nitrogen etc. that dissolve in water are then along with water of condensation enters steam trap, the steam of steam trap enters vapour compressor, done work by the mechanically compress of vapour compressor, the temperature of further raising steam and calorific value, the intensification steam after compression enters evaporator room; Residual waste water then flows into container for storing liquid, and entered by recycle pump and circulate next time, be provided with foam killer storage tank near container for storing liquid, both are connected by pipeline, and pipeline is provided with control valve, is controlled the use of foam killer by control valve.
Compared with prior art, the utility model has following beneficial effect:
The utility model adopts mechanical steam recompression technology, equipment used is few, technical process is simple, processing cost is low, this device mainly adopts physical method to process chemical plant wastewater, secondary pollution can not be produced and steam used can reuse, both be conducive to environmental protection, again save resource.
