Centrifugal filtering system for mud juice from cane sugar factory

Abstract

The invention discloses a centrifugal filtering system for mud juice from a cane sugar factory. The centrifugal filtering system comprises a sugar mud settling pond, a first centrifuge, a second centrifuge, a stirring tank, a storage tank and a washing water tank, wherein the sugar mud settling pond is connected with a feeding opening of the first centrifuge by a pipeline; a liquid outlet of the first centrifuge is connected with the storage tank by a pipeline provided with a first exhaust tank; a solid outlet of the first centrifuge is connected with the stirring tank through a guide pipe; the stirring tank is connected with a feeding opening of a second centrifuge by a pipeline; a liquid outlet of the second centrifuge is connected with the storage tank by a pipeline provided with a second exhaust tank; a discharging pipe for importing sludge is arranged at a solid outlet of the second centrifuge; the stirring tank is also connected with the washing water tank through a pipeline. Thesystem has the advantages that solid-liquid rapid separation of the mud juice from the cane sugar factory is realized, treatment time of materials is shortened, production efficiency is improved, loss of filtered mud sucrose content and washing water amount are reduced, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of filtering sugarcane sugar factory mud juice, in particular to a centrifugal filtration system for sugarcane sugar factory mud juice. Background technique [0002] The development of sugarcane sugar industry in Guangxi has very superior resource advantages, location advantages, quality cost advantages and market expansion advantages. Guangxi is a key sugar-producing area in the country. It has a superior geographical location, abundant rainfall, and sufficient sunshine. It has unique geographical resources for planting sugarcane. Sugarcane production accounts for more than 62% of the country. It is the main sugarcane-producing area in the country. In recent years, Guangxi has introduced capital and technology through internal introduction and external connection to promote the development of the sugar industry to a higher level, scale and level. The sugar industry in Guangxi has developed rapidly, and a gr...

Problems solved by technology

However, these equipments have the following disadvantages in the process of production and use: first, the water content of the discharged filter mud is relatively high, reaching more than 70%, which increases the amount of transportation and treatment discharged from the factory by the enterprise, and is not conducive to the cleaning of the environment; The sugar content of the filter mud is 6.3% (the sugar content of the wet filter mud is 1.9%), and the sugar loss is relatively large; the third is that the amount of washing water is relatively large when the vacuum suction filter is used to process the mud juice, reaching about 8%, which is not conducive to the subsequent process (evaporation) Material handling, increased evaporation, increased energy consumption

[0006] In order to recover the sugar in the mud juice and increase the production of white sugar, many vacuum suction filters without filter cloth increase the amount of water washing. Due to the large amount of washing water and the high water content of the filter mud, it needs to be discharged, which will cause certain pollution to the environment and transportation. Difficult, difficult to further comprehensive utilization, causing a certain pressure on the environment; at the same time, due to the excessive washing water volume, the filtrate hammer is low, increasing the evaporation of the subsequent process
