Description
Technical field
The present invention relates to a kind of evaporation and concentration processing units of hc effluent, use air as more particularly, to one kind useless
The steam carrier that water evaporation comes out can make full use of the useless low-temperature heat source such as solar energy, low temperature exhaust heat waste heat to be used as heating thermal energy,
It is that a kind of air-hc effluent directly contacts evaporation mode concentration device again, belongs to difficult industrial wastewater (high-concentration waste
Water) environmental protection and energy saving minimizing processing technical field.
Background technique
The industries such as China's pharmacy, printing and dyeing, papermaking, chemical industry are in critical role in national economy, but this kind of enterprise is daily
The hc effluent water of generation is little, but COD is greater than 105, salt concentration is more than 10%, belongs to difficult, used water difficult to degradate.
Since current existing environmental protection treatment technology and equipment is difficult to reach environmental protection treatment requirement, many enterprises are disobeyed using stealthily in line
Local environment is seriously polluted in judicial act, so that problem of environmental pollution caused by these difficult industrial wastewaters becomes current China
One urgent problem.
Film concentration technology is used widely in municipal wastewater, industrial wastewater field in recent years, so that industrial wastewater,
Sanitary sewage concentration is able to continue to improve, and sewage total amount is greatly reduced.But the sewage after film is concentrated in practical projects
It is still difficult to reach the requirement of innoxious high temperature incineration.This is because sewage salt concentration is lower than 10%, after concentrated after film concentration
Sewage still contains compared with juicy, burns reprocessing there is still a need for consumption mass energy, leads to higher cost.Moreover, it burns and produces
Raw superheated vapor will cause irreversible lesion to equipment, it is therefore desirable to continue at minimizing to the hc effluent after film concentration
Reason.
The method for concentration of hc effluent thermal evaporation at present is most common technology, in order to reduce evaporation energy consumption, many skills
Art makes full use of the secondary steam latent heat re-evaporation hc effluent being evaporated, such as multiple-effect evaporation, steam recompression technology.
It finding by patent retrieval and market survey, hc effluent thermal concentration technology is used for difficult waste water at present, we
It was found that there is Railway Project to be still difficult to effectively be solved: 1) since higher salt content leads to stronger corrosion in hc effluent
Property, waste water has strong corrosivity to canister and heat exchange equipment；2) evaporation equipment mostly uses greatly in traditional evaporation technique
Metal material manufacture, hc effluent are easily precipitated in metal surface fouling or pipe, cause serious scale problems or pipeline stifled
Plug problem, concentration systems can not normal continuous operations；3) multiple-effect evaporation, mechanical compression re-evaporation complex process equipment, investment are inclined
Height is suitble to the processing of a large amount of waste water, and cost performance is low when handling a small amount of waste water；4) thermal evaporation techniques are steamed suitable for salt at present
Hair, once it is higher to have an opportunity, it is necessary to it is removed using pretreatment mode, integrated artistic is complicated.
On the whole, traditional thermal concentration technology existing at present is not suitable in a small amount of high load wastewater treatment, we are necessary
Find energy conservation and environmental protection processing technique and dress that a kind of suitable, adaptable concentration and evaporation technique realizes hc effluent minimizing
It sets.
