Abstract
The invention relates to a method for preparing a soil regulator by utilizing waste bleaching clay, and the technological steps are as follows: (1) sending the waste bleaching clay into a sealed auger, simultaneously introducing saturated steam into the auger, increasing the temperature of the waste bleaching clay to 80 DEG C-95 DEG C and increasing the humidity; (2) sending the waste bleaching clay after increasing the temperature and increasing the humidity into an oil press for pressing residual oil in the partial waste bleaching clay, and controlling the residual oil rate of the waste bleaching clay after pressing to be 6%-8%; (3) sending the waste bleaching clay after the pressing into a smashing machine for smashing till 60 meshes-80 meshes; and (4) carrying out inspection and packaging. The method can effectively treat polluting industrial wastes of edible oil processing enterprises and realize significant economic benefits and social benefits.
Description
Technical field
The present invention relates to a kind of method of utilizing waste bleaching clay to prepare soil redeposition.
Background technology
In the refining production process of edible oil, use bleaching clay that grease is decoloured, purifies usually.Only the annual employed bleaching clay of the grease production enterprise of China is just more than 300,000 tons, and consequent waste bleaching clay is more than 350,000 tons.At present, a large amount of waste bleaching clays are not recovered utilization, but adopt the processing mode of landfill, not only cause the waste of resource, also bring land occupation and environmental pollution problems simultaneously.
Summary of the invention
The objective of the invention is at the problems referred to above, a kind of method of utilizing waste bleaching clay to prepare soil redeposition is provided.
The method that the present invention utilizes waste bleaching clay to prepare soil redeposition comprises following processing step:
(1) waste bleaching clay is sent into sealed auger, in auger, feed saturation steam simultaneously, make the temperature of waste bleaching clay rise to 80 ℃～95 ℃, and humidification;
(2) will heat up and humidification after waste bleaching clay send into oil press zhai squeezing, squeeze the Residual oil in the part waste bleaching clay, and the residual oil content of control squeezing back waste bleaching clay is 6%～8%;
(3) the waste bleaching clay cake after will squeezing is sent into and is crushed to 60 orders～80 orders in the pulverizer;
(4) test packing.
The present invention uses sealed auger, saturation steam to carry out gentle humidification of adding of waste bleaching clay raw material, in the residual oil content of the waste bleaching clay after satisfying the squeezing process requirement, being convenient to control squeezing, the equipment configuration is simple, handled easily control, production efficiency height.
The organic content of soil redeposition of the present invention is 30%～35%, and iron content is 1.50%～1.55%, and pH value 2.2～2.3 is particularly suitable as the soil redeposition and the fertilizer of alkaline land improving.
The invention has the beneficial effects as follows:
1, handled the contaminative trade waste of edible oil processing enterprise effectively, both solved the landfill disposal land occupation and caused environmental pollution problems, enterprise has been reduced to handling the expense that this waste will be paid.
2, from waste bleaching clay, squeeze the waste oil of some amount, be used for the raw material of biofuel, can obtain considerable economic.
3, final product is the soil redeposition that the saltings is had improving effect, waste pollutant has been become the product that very high economic worth is arranged.
Embodiment
Embodiment
(1) waste bleaching clay by producing in the refining raw food oil process that will collect is sent into sealed auger, simultaneously through the uncovered saturation steam that feeds in auger of auger, makes the temperature of waste bleaching clay rise to 90 ℃, and makes the waste bleaching clay humidification;
(2) will heat up and humidification after waste bleaching clay send into 90 type oil press zhai squeezings, squeeze the Residual oil in the part waste bleaching clay, and the residual oil content in the waste bleaching clay of control squeezing back is 7%;
(3) the waste bleaching clay cake after will squeezing is sent into and is crushed to 70 orders in the pulverizer;
(4) test packing.
Claims (1)
1, a kind of method of utilizing waste bleaching clay to prepare soil redeposition is characterized in that its processing step is:
