Apparatus for preparing bio-fuel by self-supplied thermal cycling fluid bed

Abstract

The invention relates to a device of heat self-supplying circulating fluidized bed for producing biological fuels. The device is characterized in that a temperature control device is connected with a material pre-processing device, a circulating fluidized pyrogenation device, a hierarchical liquid oil preparing device and a gas separation and enrichment device; the material pre-processing device is connected with the circulating fluidized pyrogenation device which is connected with the hierarchical liquid oil preparing device; and the hierarchical liquid oil preparing device is connected with the gas separation and enrichment device. The invention fully utilizes the characteristics of intense heat transfer between gas and solid phases and large strength of thermal current of fluidized bed, etc. and realizes lightening speed pyrogenation of biomass and solid wastes and fast precipitation of produced gases and recycling and utilization of solid products; the comparatively comprehensive, simple and convenient device can guarantee not only the productivity of the products, but also the excellent quality of the products and has simple and convenient subsequent processing.

Description

technical field [0001] The invention relates to a device for producing biofuel, in particular to a device for catalytically producing biofuel in a self-heating circulating fluidized bed. Background technique [0002] my country is a large agricultural country with abundant biomass raw materials and waste organic matter. With the increasing frequency of human activities, the problem of garbage produced is becoming more and more serious. The 3 billion tons of livestock and poultry manure produced in my country every year has become a serious source of water pollution. Thousands of years of smoky and low-efficiency direct combustion energy consumption Demanding improvement, 3.5 million rural areas in remote mountainous areas do not have access to electricity. But at present, my country's commercialized biomass energy only accounts for about 0.5% of primary energy consumption, which is a huge gap compared with developed countries. Utilizing these organic matters produced in lif...
