Description
Technical field
This utility model relates to the mother solution containing high concentration organophosphor, nitrogen and salinity of a kind of pesticide industry and carries out minimizing, innoxious, resource environmental protection treatment technology, particularly relate to a kind of recycling mother solution of glyphosate and utilize system, belong to waste liquid, waste gas, the environmental technology field of useless solid disposal of waste gas, water and industrial residue.
Background technology
Glyphosate production process produce a large amount of containing triethylamine, glyphosate, glycine, phosphorous acid, glyphosine, methanol, formaldehyde and the production waste water of high salt concentration, mother solution is mainly carried out concentrating removing part salinity by domestic glyphosate production producer, then add the former powder of glyphosate, be configured to 10% gyphosate solution and sell.Owing to chronic administration contains 10% water preparation of a large amount of inorganic salt, causing serious soil compaction and salinization of soil, the formaldehyde in water preparation, glyphosine etc. enter soil and water body simultaneously, and ecological environment and human body are also had bigger potential hazard.Therefore, in February, 2009 Ministry of Agriculture, Ministry of Industry and Information combine issue No. 1158 bulletin, the gyphosate solution of clear stipulaties active constituent content less than 30% is wholly off production before the end of the year 2009, with produce water preparation will stop before the end of the year 2011 sale and use.
Glyphosate mother solution complicated component, the mother liquor composition difference that different synthesis techniques produces is bigger, mainly include the materials such as triethylamine, glyphosate, glycine, phosphorous acid, glyphosine, methanol, formaldehyde and high salt concentration, if carried out recycling, production cost can be saved, improve Enterprise Integrated competitiveness.
Available low-concentration alkali liquor desorption after activated carbon adsorption glyphosate, overall desorption was inefficient at that time, and about 57%, when being desorbed incomplete active carbon reclamation, adsorption effect is significantly restrained, and activated carbon price is higher, the glyphosate mother solution processing cost as enormous amount will be greatly improved.Cl-Can be with the site on glyphosate anion competition anion exchange resin surface, at Cl-Even glyphosate can be stoped completely to adsorb during too high levels, for the mother liquid disposal of high content of salt, it is necessary to first to reduce Cl in mother solution-Content.Although Cl-Less to the Adsorption Effect of ferrum, aluminum oxide, but the existence of phosphate radical, orthophosphite has more apparent impact to it, and the treatment effect for the glyphosate mother solution of high COD, high total phosphorus and high salinity needs to be verified further.Embrane method is to have carried out industrialized application at present, but the many kinds of substances such as the phosphite in mother solution significantly affect the service life of membrane module, and fouling membrane is serious, frequently changes membrane module and brings bigger financial burden to enterprise.Chemical precipitation method obtains glyphosate-metal salt precipitate thing, uses which kind of mode to make glyphosate effectively be reclaimed and also to study further.
Therefore, glyphosate waste water is administered has become the main bugbear that puzzlement pesticide enterprise produces, survives.
Incineration technology is a kind of simple, efficient, feasible method for treating waste liquid, and burning method is used for processing difficult biochemical treatment, concentration is high, toxicity is big, the organic liquid waste of complicated component is a technology having application prospect.It both can incinerate harmful substance, can recycle again waste heat, reduce processing cost, reaches comprehensive utilization of waste materials, the purpose of protection environment.The processing technological flow of different organic liquid wastes regards waste liquid character and determines, the organic liquid waste that, calorific value the highest for COD is the highest can be directly entered incinerator and carry out burning disposal；And be not the highest waste liquid for calorific value, then can add auxiliary fuel and help the burning of waste liquid；The organic liquid waste higher for water content can burn after first carrying out evaporation and concentration.
Containing a large amount of industrial chemicals in high concentration salty organic waste liquid, at present, the CIU (except alkali collection) using incineration technology to process high concentration salty organic waste liquid does not carries out recycling to the product after burning, and causes the waste of secondary pollution and resource.
Patent CN103062777A proposes two-part incinerator and CIU, including vertical heater, horizontal chamber furnace (oven), Waste liquid atomization rifle, fuel combustion rifle, the circulating fire grate of scale, second-time burning expansion chamber, heat exchange unit, smoke eliminator etc., wherein part-structure utilizes system similar with the application one recycling mother solution of glyphosate.But two-part incinerator and CIU described in this patent have the disadvantage that: the outlet of (1) vertical heater is directly connected with second-time burning expansion chamber; the a large amount of saliferous solid particles carried in flue gas are heated again; so that it becomes molten state; the saliferous solid particle of the molten state of sedimentation can block the mud hole of second-time burning expansion chamber; the saliferous solid particle of the molten state being brought into heat exchange unit can adhere on heat exchanger tube; cause heat exchange efficiency to reduce, even block exhaust gases passes；(2) scale circulating fire grate front is for arranging hopper, it is impossible to unburned saliferous solid particle completely being sent back to horizontal chamber furnace (oven) again and continues to burn, the industrial chemicals impurity produced in burning process is more；(3) Waste liquid atomization spray gun is two fluidic structures atomizing guns, outer layer is compressed air piping, rule of thumb under room temperature, glyphosate mother solution viscosity is higher, it is required to heating and reduces its viscosity coefficient, and compressed air mostly is room temperature, uses compressed air to cool down glyphosate mother solution as atomizing medium, viscosity coefficient increases, blocking rifle head, affects atomizing effect, and atomizing effect is the key factor affecting efficiency of combustion；(4) incineration temperature is not defined by vertical heater, horizontal chamber furnace (oven) and second-time burning expansion chamber, though be all solid material from described collection can be seen that for two-stage combustion be the most all low-temperature burning, Organic substance in waste liquid can not be burned completely, also cannot meet country's " dangerous waste incineration Environmental capacity standard "；(5) through Waste liquid atomization spray gun spray into the glyphosate mother solution of vertical heater in concentration, glyphosate mother solution containing substantial amounts of water, making this part water reach combustion temperature in hearth needs to consume substantial amounts of auxiliary fuel, causes the waste of the energy.
