Pretreatment equipment for biological fuels and production process thereof

Abstract

The invention relates to pretreatment equipment for biological fuels and a production process thereof. The equipment comprises a dehydrating mechanism, a decolouring and deodorizing mechanism, and a filtering and impurity-removing mechanism. The dehydrating mechanism is connected with a dehydration charging pump for conveying to-be-processed raw materials. A dehydrated oil delivery pump, arranged between the dehydrating mechanism and the decolouring and deodorizing mechanism, is connected with the dehydrating mechanism and the decolouring and deodorizing mechanism. The material discharge tube of the decolouring and deodorizing mechanism is connected with the filtering and impurity-removing mechanism. The dehydrating mechanism and the decolouring and deodorizing mechanism are connected with a waste gas collection part. The filtering and impurity-removing mechanism is connected with a compressed air source and a steam source. Biological fuels produced by the above equipment are light in taste, light in color and free of water and sediments. The processing of biological fuels is refined, while the repeated and useless processing is avoided. The working load of the equipment is lightened, and the production efficiency is improved. Moreover, the discharge of pollutants is avoided.

Description

technical field [0001] The invention relates to the technical field of production and preparation of biological oils, in particular to a pretreatment device and a production process for producing biological oils by using swill oil and gutter oil. Background technique [0002] Most of the raw materials of bio-oil come from waste oils such as acidified oil and gutter oil. Due to the variety of raw materials and complex sources, these waste oil raw materials contain a large amount of sundries, and the raw materials need to be dehydrated, decolorized, deodorized, and impurity removed. Process pretreatment, the traditional waste oil to remove impurities usually adopts natural sedimentation process to remove part of solid phase impurities and water, while there are still some solid impurities in raw materials. [0003] At the same time, the existing production and processing equipment for waste oil raw materials not only has high manufacturing costs, but also the produced bio-...

AI Technical Summary

Problems solved by technology

[0003] At the same time, the existing production and processing equipment for waste oil raw materials not only has high manufacturing costs, but also the produced bio-oil has residual impurities and moisture, the color of the oil is turbid, the smell is heavy, the quality of the produced bio-oil is poor, and the production and utilization of waste oil raw materials The rate is low, and there is repeated processing, which consumes a lot of energy, discharges residual waste, and pollutes the environment
