Biomass cracking device utilizing high-temperature liquid

Abstract

The invention relates to a biomass cracking device utilizing high-temperature liquid. The device is characterized in comprising a power assembly, a delivery transmission assembly connected with the power assembly, a reaction device, and a condensation device and a collection device connected with the reaction device. High-temperature liquid is placed in a reaction furnace. With the power assembly, a material is delivered to the reaction furnace through the delivery transmission assembly. In the reaction furnace, the high-temperature liquid is used for isolating oxygen and for conducting heat with a high speed, such that the material is subjected to cracking. The cracked product enters the collection and condensation devices. The entire technical scheme has the advantages of simple operation and high utilization rate. With a support, the tightness in the reaction furnace body is fully ensured, such that a smooth reaction is further ensured. According to the technical scheme, heating devices are arranged inside or around the reaction furnace body or outside a delivery pipe, such that a better condition is provided for a sufficient reaction.

Description

technical field [0001] The invention relates to a cracking device, in particular to a biomass cracking device using high-temperature liquid. Background technique [0002] Biomass, in a broad sense, refers to all renewable substances from animals and plants other than fossil fuels in organic matter. Biomass energy is directly or indirectly through the photosynthesis of green plants, converting solar energy into chemical energy and then fixing and storing energy in organisms. Biomass mainly includes forestry biomass, agricultural waste, aquatic plants, energy plants, municipal waste, organic wastewater, human and animal manure, etc. With the depletion of fossil fuels, biomass as a renewable clean energy is increasingly valued by countries all over the world. At present, biomass energy accounts for about 14% of the world's total energy consumption, ranking fourth after petroleum, coal and natural gas. The International Energy Agency predicts that it will be an important part ...

Problems solved by technology

Because the liquid products obtained from biomass conversion have high energy density, are easy to transport, have little connection with conversion and application, and are easy to use, they have attracted the attention of scholars from various countries; The rapid heating and pyrolysis of the Canadian Ensyn Engineering Association, the cyclone melting cracking of the US Solar Energy Research Institute (SERI) and the fluidized bed rapid pyrolysis of the University of Waterloo (WFPP) in Canada all require high-temperature gas as a carrier and protective gas to isolate oxygen. and transfer heat, but a large amount of heat is taken away by these gases in the process of collection and condensation, resulting in a large amount of energy consumption, low economic performance, and not easy to promote

Another example: the rotating cone reactor of the Chemical Reaction Engineering Department of the University of Twente in the Netherlands requires a certain amount of shielding gas, but also has high energy consumption, and requires high process control conditions, which is not easy to promote

The cracking mill technology of the Colorado School of Coal Mines (CSM) in the United States also requires a certain amount of shielding gas, and also has high energy consumption, and the grinding disc itself has relatively large wear and erosion, requiring frequent replacement of expensive copper grinding discs, which is also economical. It is not easy to popularize; in short, due to the relatively high reaction conditions and high cost of biomass cracking, the utilization rate is extremely low. Although those skilled in the art have been devoting themselves to researching suitable cracking devices, they have not yet obtained an ideal technical solution.
