Abstract
The invention discloses a treatment method for acetic acid evaporation residue, which is an alkali resolution method. The treatment method is characterized by comprising the following steps of: pouring carbide slag and water in a resolution reaction kettle, stirring and heating to boil, then adding the discharged high-temperature acetic acid evaporation residue in the resolution reaction kettle, and stirring and reacting until the pH value is 7-10, wherein the mass ratio of the acetic acid evaporation residue to carbide slag to water is 100: (45 to 55): (50 to 70). The solid wastes treated by the treatment method disclosed by the invention are loosened in structure and easy to crush, manually bag and combust after being cooled, and capable of being directly doped in fly ash and to be used as a fluidized bed boiler fuel without black smoke. According to the treatment method disclosed by the invention, the difficult problem that the originally-treated solid wastes, namely, acetic acid evaporation residue is massive, hard, and not easy to crush and combust after being cooled is solved.
Description
One, technical field
The present invention relates to a kind of processing method of solid waste, solid waste---the processing method of acetic acid evaporation residue that specifically a kind of polyvinyl alcohol produces in producing.
Two, background technology
In polyvinyl alcohol is produced, produce the higher boiling tarry matters of some in rectification working process acetic acid evaporation process, be the acetic acid evaporation residue, the Main Ingredients and Appearance of this solid waste: acetic acid 15-30%, active carbon 2-5%, zinc acetate 1-3%, polyvinyl acetate 25-50%, other high polymers 15-30%.
When the acetic acid evaporation residue has just discharged from acetate evaporator, temperature is higher, is black tarry fluid, and bad smell is arranged, and becomes bulk, hard difficult pulverizing after cooling.The acetic acid evaporation residue can burn, combustion heat 4000-8000kcal/kg.
Processing this solid waste conventional method is the cooling rear smaller piece shape that manually is cut into, and send professional solid waste to process company's burning disposal, during burning, has a large amount of black flue dust to exist, and burns extremely incomplete, and residue is more, and environmental pollution is large; Artificial cutting consumes a large amount of manpowers.
In carbide polyvinyl alcohol production process, also produce another kind of solid waste simultaneously, i.e. carbide slag, its Main Ingredients and Appearance is calcium hydroxide, the conventional art of processing carbide slag be using it as cement raw material or in and acidic materials use.
Three, summary of the invention
The present invention is for avoiding the existing weak point of above-mentioned prior art, and a kind of processing method of acetic acid evaporation residue is provided, and makes this residue be converted into auxiliary fuel and without black smoke.
The present invention is that the technical solution problem adopts following technical scheme:
The processing method of acetic acid evaporation residue of the present invention is the alkali resolution method, be characterized in: at first carbide slag and water input are cleared up in reactor, stirring is warmed up to boiling, then the high temperature acetic acid evaporation residue of discharge is added and clears up in reactor, and stirring reaction to pH value is 7-10; The mass ratio of acetic acid evaporation residue and carbide slag and water is: 100: 45-55: 50-70.
The characteristics of the processing method of acetic acid evaporation residue of the present invention also are: the mass ratio of acetic acid evaporation residue and carbide slag and water is: 100: 50: 60.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention changes the cooled physical property of solid waste acetic acid evaporation residue, especially it is loosely organized, be graininess, do not need to do special cutting, pulverization process just can directly pack as grafter with light instrument, its reason is because character after the key component polyvinyl acetate in former acetic acid evaporation residue and calcium hydroxide reaction is sent out change, and it is block that this component is after directly causing former solid waste cooling, hardly is difficult for cutting and grinding; After reaction, polyvinyl acetate is converted into polyvinyl alcohol, and viscosity reduces greatly.
2, the present invention does not make the combustible character of solid waste change, and combustion efficiency is better, and still less, this is because it is loosely organized to black smoke, during the fine particle burning, with oxygen, contacts more abundant.
3, the solid waste of processing through the inventive method, the pH value is neutral meta-alkali, does not corrode fluidized-bed combustion boiler equipment, is applicable to mixing in flyash using as fluidized-bed combustion boiler fuel.
Four, the specific embodiment
Embodiment 1:
50 parts of carbide slags and 60 parts of water are added to a jacketed, have in the reactor of stirring, start and stir, toward chuck, pass into and be steam heated to the boiling shape, be about 100 ℃; 100 parts of the high temperature acetic acid evaporation residues that discharge in acetate evaporator are added in reactor, after stirring 30 minutes, the pH value of material in the measured reaction still.
When the pH value is 7-10, close the chuck Steam Heating, stop stirring, open emptying valve, discharge of materials is to collecting pit.
The pH value, lower than 7 o'clock, is added a small amount of carbide slag in reactor, regulates the pH value for being not less than 7.
Solid is abandoned thing through naturally cooling descendant's frock bag in collecting pit, send the fluidized-bed combustion boiler use that acts as a fuel.
Embodiment 2:
45 parts of carbide slags and 70 parts of water are added in reactor, and operation is with embodiment 1 later;
Embodiment 3:
45 parts of carbide slags and 50 parts of water are added in reactor, and operation is with embodiment 1 later;
Embodiment 4:
55 parts of carbide slags and 70 parts of water are added in reactor, and operation is with embodiment 1 later;
Embodiment 5:
55 parts of carbide slags and 50 parts of water are added in reactor, and operation is with embodiment 1 later.
Claims (2)
1. the processing method of an acetic acid evaporation residue, be the alkali resolution method, it is characterized in that: at first carbide slag and water input are cleared up in reactor, stirred and be warmed up to boiling, then the high temperature acetic acid evaporation residue of discharge is added and clears up in reactor, stirring reaction to pH value is 7-10; The mass ratio of acetic acid evaporation residue and carbide slag and water is: 100: 45-55: 50-70.
2. the processing method of acetic acid evaporation residue according to claim 1, it is characterized in that: the mass ratio of acetic acid evaporation residue and carbide slag and water is: 100: 50: 60.
