Description

A kind of stove ash cleaning agent and preparation method thereof
Technical field
The invention belongs to industrial solid wastes processing technology field, be specifically related to a kind of industrial waste salt recycling side Method.
Background technology
Inorganic containing Organic substance and other poisonous and harmful substances that industrial waste salt refers to produce in industrial processes Abraum salt；It is mainly derived from petrochemical industry, pesticide, medicine and fine chemistry industry and produces solid-liquid separation, solution condensing crystallizing and associated row The processes such as industry technique waste water pretreatment.Domestic enterprise produces industrial waste salt about 30 50 ten thousand tons/year at present, and industrial waste salt mainly becomes Part is sodium chloride, possibly together with other salts such as a small amount of sodium sulfate, sodium carbonate, sodium phosphate, sodium hydroxide.Process Industry Waste at present The method of salt mainly has:
1, direct heating power burning method: the method is that waste salt dregs is directly added to incinerator top, material under the most above, adds Hot temperature about 900 degree, inorganic salt is melted flows into furnace bottom, reclaims after cooling, and the Organic substance included at high temperature volatilizees and decomposes, Furnace gas enters secondary combustion chamber and burns further or discharge after direct physical chemical treatment.
But the method needs that waste salt dregs carries out granule that is predrying and that require waste salt dregs, and uniformly and particle diameter is the least, So that granule internal temperature gradient minimizes, but along with air blast enter, as easy as rolling off a log furnace roof portion formed fused salt rain, follow-up respectively Along with the inwalls such as face assembly and its equipment pipe that successively decrease of temperature in unit, easily causing device to block and damage, industrialization is steady There is not been reported to determine device.
2, refined rear secondary concentration crystallization treatment is dissolved: the method is to be redissolved in fresh water by waste salt dregs, passes through Again reclaim after condensing crystallizing after chemical treatment.But the method cost of disposal is high, and secondary waste water is had to produce, physico after dissolving Learning the effect disposed to be difficult to ensure, the salt water content that recrystallization reclaims is higher, and some there is also substantial amounts of water of crystallization, and secondary utilizes It is worth low.
3, innoxious landfill stabilization: the method is by the mixing of all kinds of waste salt dregs and after the firming agent solidifications such as concrete, presses Special landfill stabilization is carried out according to National Hazard waste management and the relevant laws and regulations of disposal and technical specification.This method of disposal cost is high High, not only take substantial amounts of soil, there is also because the foeign elements such as geological disaster cause the risk of secondary environmental hazard simultaneously.
The problems such as three of the above method all has processing cost high, the wasting of resources, therefore, the most often it can be seen that such Report: state's laws regulation is put in ignoring by some enterprise, puts environmental risk in ignoring, or pretends to be Nacl or food with industrial waste salt Circulate market with salt, affect the life and health of people；Or for reducing Solid Waste Treatment expense, industrial waste salt is stealthily filled out Bury, bring great hidden danger to Environmental security.
Summary of the invention
The invention aims to overcome drawbacks described above, it is provided that a kind of stove ash cleaning agent, it is will to produce in Chemical Manufacture Raw industrial waste salt, by after drying with other chemical raw material scientific matching, then the machining such as size-reduced, stirring mixing, system Standby one-tenth stove ash cleaning agent, on the one hand reduces the processing cost of industrial waste salt, on the one hand provides a kind of efficient, energy-conservation stove deashing Agent, it is achieved resource reutilization, can avoid industrial waste salt stealthily to fill the pollution hidden trouble brought to environment simultaneously.
