The filtrate obtained when this step filters needs to regulate pH value, its object is to make the pH value of the gasification slip of preparation drop within 6.0～8.0 scopes。
If the pH value regulated is more than 6.0～8.0 scope, equipment and pipeline can be caused gasification slip prepared by corrosion, meta-alkalescence can make the easy fouling of system pipeline by gasification slip prepared by slant acidity。
The inorganic acid aqueous solution used when regulating pH value is such as 1-5N hydrochloric acid, nitric acid, sulphuric acid or phosphate aqueous solution；The inorganic base aqueous solution used is such as 1-5N sodium hydroxide, potassium hydroxide, sodium carbonate or wet chemical。
Using mineral acid and inorganic base aqueous solution concentration to be not critical in this step, concentration 1-5N is practical。
The waste liquid being adjusted pH value adopts three kinds of processing modes according to following situation:
First kind of way relates to the liquid wastes containing recovery value material；
The second way relates to the liquid wastes not containing recovery value material；
The third mode relates to that toxicity is big, high volatility, be difficult to slurrying and do not contain the liquid wastes of recovery value material。
Describing three kinds of processing modes separately below, concrete condition is referring to accompanying drawing 1:
For the first processing mode, the process step of its waste liquid is as follows:
Needing to be reclaimed during the material that described waste liquid contains recovery value, its residual liquid is delivered in grinding machine by feed measuring equipment, referring specifically to accompanying drawing 1 (a)。
In the present invention, have the material of recovery value it should be understood that in waste liquid content higher and with low cost adopt the recuperable material with economical and practical value of conventional method。
Described have the material such as ethylene glycol, acetone of recovery value, toluene, dichloromethane, butyl acetate。
Then step D preparation of raw material is carried out, the weight ratio 35～55,5～20,10～30,0.5～1.5 and 20～40 of residual liquid, additive and water that solid waste powder that the coal dust that obtains according to step A, step B obtain, step C obtain, it is delivered to ground and mixed in grinding machine through respective feed measuring equipment respectively, obtains a kind of gasification slip。
Described additive is that one or more are selected from the additive of lignosulfonates, humate or acrylates。Described lignosulfonates, humate or acrylates are sodium, potassium, ammonium, calcium or magnesium salt, and they are all product solds in the market。
When the amount of other raw material is in described scope, if the amount of coal dust is less than 35 weight portions, then the gasification slip calorific value prepared is on the low side, does not reach the requirement of gasification；If the amount of coal dust is more than 55 weight portions, then the gasification phosphoric acid prepared is bigger than normal, is unfavorable for the conveying of slip；Therefore, the amount of coal dust is 35～55 weight portions is rational。
