Abstract

The invention discloses a method and equipment for producing organic mixed fertilizers by comprehensive utilization of wastes in a sugar factory. A method for producing particle fertilizers by utilizing molasses-containing alcohol waste liquid, limes, coal ash, bagasse pith and lime sludge as raw materials comprises the following steps: (1) performing primary mixing on a part of alcohol waste liquid, the lime sludge and the bagasse pith in a pre-mixing device to ensure that the water content is about 50 percent so as to obtain a premix A; (2) putting the premix A, the lime and the coal ash into a feeding hopper to be mixed so as to obtain a premix B; (3) feeding the premix B into a roller-type granulator through a conveyor belt, spraying the molasses-containing alcohol waste liquid by using a spray gun in a rotation process of the roller-type granulator to perform granulation to obtain a granule C; and (4) entering a drying machine to dry at the temperature of 600-800 DEG C, screening after the granule C is dried, and packaging to obtain a product. According to the method and the equipment, the troubled problem of environment pollution caused by alcohol waste liquid in the sugar factory is solved, and the resource utilization purpose in the sugarcane industry is also achieved; the equipment is convenient to operate, low in power consumption and suitable for popularization and utilization in most fertilizer factories; moreover, abundant production cost can be saved for enterprises.

Description

technical field [0001] The invention belongs to the technical field of organic mixed fertilizer production, and relates to a method and equipment for producing organic mixed fertilizer by comprehensive utilization of sugar factory waste. Background technique [0002] Sugar enterprises will produce a large amount of filter mud, molasses alcohol waste liquid, and cane pith every year. If they are not disposed of properly, they will need to be stored in a large number of places until they are harmless. The process not only occupies a large area of ​​land, but also produces a large amount of waste due to self-fermentation. Harmful gases and liquids not only increase the burden on enterprises, but also pollute the environment. [0003] As our country attaches great importance to ecological and environmental protection issues, as a major polluter, the living space of the sugar industry has been increasingly suppressed in recent years. Among wastes, the treatment of molasses alcoh...
