Problems solved by technology

For refined sugar filter mud, due to the addition of a certain amount of diatomite filter aid in the process of producing refined sugar, the properties of the filter mud are quite different from those of carbonic acid filter mud, and there are few reports on the comprehensive development and application of filter mud. , the treatment of filter mud is generally landfilled, the environmental management cost is high, and the environmental benefit is poor

Abstract

The invention discloses a composite lime emulsifier. The composite lime emulsifier contains calcium oxide and a diatomite filtration aid which are in the weight ratio of (4.0-9.0): 1. The invention also discloses a preparation method for the composite lime emulsifier. The preparation method comprises the step of roasting sugar refining filter mud, which is generated from a process of producing refined sugar through dissolving raw sugar and serves as a raw material, for 30-120 minutes at the temperature of 750-1,200 DEG C. The invention also discloses application of the composite lime emulsifier in a sugar refining process. According to the composite lime emulsifier and the preparation method therefor and application thereof, the waste is changed into the valuable, and the filter mud generated from a refined sugar production process is completely used, so that social, environmental and economic benefits for refined sugar production enterprises are increased.

Description

technical field [0001] The invention relates to a preparation method and application of a composite lime emulsifier, in particular to a method and application of a composite emulsifier prepared from refined sugar filter mud. Background technique [0002] Sulfurous acid-phosphoric acid process sugar filter sludge, carbonation process sugar filter sludge, and refined sugar filter sludge are a large amount of waste produced by the sugar industry, which has caused great environmental pollution problems. After long-term and unremitting research efforts by scientific workers, the comprehensive development and application of filter mud has achieved fruitful results, and the environmental pollution caused by filter mud has been reduced year by year. For example, most of the sulfurous acid-phosphoric acid method sugar filter mud is used as raw material for the production of compound fertilizers; the first carbon juice and second carbon juice filter mud can be used as raw materials fo...
