Background technology
The ammonium chloride water content is to weigh the important indicator of ammonium chloride product quality, State Standard of the People's Republic of China GB/T2946-2008 regulation, in ammonium chloride, the quality mark must be below 1.0%, therefore, in the production process of ammonium chloride, in ammonium chloride, the filtration of moisture has material impact to the quality of the finished product.
Usually, need first the ammonium chloride of producing to be carried out centrifuging.Because the dewatering efficiency of whizzer is limited, the water content of the ammonium chloride after the process centrifuge dewatering is all more than 6%.Ammonium chloride need to be dried through after centrifuge dewatering., distillation can occur or decompose under hot environment due to ammonium chloride, therefore, usually with its slowly oven dry in 48 ℃ of-57 ℃ of thermal environments.In order to reduce moisture content in ammonium chloride, usually adopt following several modes: (1) increases filter plant, increases the filtration scale, extends the material filtration time; (2) improve bake out temperature, extend drying time.Yet, adopt the filtration scale that increases, increase filter plant, extend the mode of filtration time, although can reduce the moisture content in ammonium chloride, cost of equipment and operation and maintenance cost are higher, invest larger.Improve bake out temperature, extend drying time the moisture content in ammonium chloride is up to state standards, but be subjected to the impact of production system and ammonium chloride self property, operation easier is large, effect is relatively poor, simultaneously, also can cause the production capacity of ammonium chloride to reduce, increase the production cost of ammonium chloride.
Therefore, research and develop and a kind ofly can improve filtering rate, reduce the ammonium chloride moisture content, and do not affect the Production of Ammonium Chloride quality, Production of Ammonium Chloride easy to use is significant with the precipitation agent.
Summary of the invention
Goal of the invention of the present invention is: for the problem of above-mentioned existence, a kind of ammonium chloride fluid loss agent and preparation method thereof is provided, after ammonium chloride fluid loss agent of the present invention joins in ammonium chloride, can enlarge markedly the filtration efficiency of whizzer, reduce the moisture content in ammonium chloride product, improve the production capacity of drying unit, reduce the energy consumption of oven dry link, shorten time of drying, therefore, the present invention has economic benefit preferably.

The mol ratio of described maleic anhydride and sodium bisulfite is 1:1.1-1.3.
In the dodecyl iso-octyl maleic acid diester sodium sulfonate aqueous solution that is obtained by aforesaid method, the quality percentage composition of dodecyl iso-octyl maleic acid diester sodium sulfonate 〉=50%.
Wherein, the reaction equation of preparation dodecyl iso-octyl maleic acid diester sodium sulfonate is as follows:
Be used for the preparation method of described ammonium chloride fluid loss agent, comprise the steps:
The Dodecyl trimethyl ammonium chloride aqueous solution, isooctyl alcohol, water are joined in reactor by proportioning stir, add the dodecyl iso-octyl maleic acid diester sodium sulfonate aqueous solution in whipping process, mixing gets final product.
During use, use this ammonium chloride of 0.2～0.5 ㎏ with the ratio of precipitation agent in producing 1 ton of finished product ammonium chloride, add ammonium chloride fluid loss agent in ammonium chloride, then the mixture that obtains is carried out centrifuging and get final product.
Dodecyl iso-octyl maleic acid diester sodium sulfonate in the present invention and Dodecyl trimethyl ammonium chloride adopt the form of the aqueous solution, are convenient in process of production, and raw material is mixed.
In ammonium chloride when adding ammonium chloride fluid loss agent of the present invention to the whizzer filtration, bioactive molecule in ammonium chloride fluid loss agent can uniform spreading to the ammonium chloride particle surface, asymmetric hydrophobic group wherein outwards stretches, thereby destroy the hydration shell on ammonium chloride particle surface, thereby greatly reduce the multilayer absorption of bioactive molecule, improve the perviousness of water in ammonium chloride, accelerate the filtration speed of water, increase the filtration efficiency of whizzer, reduce the moisture content in ammonium chloride product.The contriver finds through great many of experiments, a small amount of this ammonium chloride fluid loss agent of centrifuge treating interpolation that filters at ammonium chloride can improve filtration speed, reduce the water content of ammonium chloride product, because ammonium chloride can not be taked high temperature drying, otherwise the loss meeting of ammonium chloride increases greatly, and therefore, the method has reduced the energy consumption of rear end drying, improve the production capacity of drying efficiency oven dry and device, reduced the energy consumption of oven dry link.
Ammonium chloride fluid loss agent of the present invention can significantly improve the ammonium chloride filtering rate, reduces the ammonium chloride moisture content, reduces time of drying, enhances productivity, and has higher economic benefit.
