Novel down pipe pyrolysis liquefying system in ceramic heat storage ball cyclic heating mode

Abstract

The invention relates to a novel down pipe pyrolysis liquefying system in a ceramic heat storage ball cyclic heating mode, and belongs to the technical field of renewable energy source utilization. The novel down pipe pyrolysis liquefying system is characterized by comprising a double-barreled heat carrier elevator, a first heat carrier storage bin, a cyclic fluid bed type heat carrier heater, a gas and solid separator, a second heat carrier storage bin, a V-shaped casing pipe reactor and a heat carrier separator which are in sequential cyclic connection. The upper portion of the double-barreled heat carrier elevator is connected with the first heater carrier storage bin through a pipeline, the upper portion of the cyclic fluid bed type heat carrier heater is connected with the gas and solid separator through a pipeline, a first biomass feeding device is connected to the lower portion of the cyclic fluid bed type heat carrier heater, a second biomass feeding device is connected to the upper portion of the V-shaped casing pipe reactor, and the bottom of the heat carrier heater is connected with a gas mixing controller through a pipeline. An angle-adjustable baffle is arranged in the heat carrier heater. The combustion heat of the cyclic fluid bed type heat carrier heater and the waste heat of high-temperature flue gas can be fully utilized, and the novel down pipe pyrolysis liquefying system is high in biomass pyrolysis liquefying efficiency, low in cost and stable in operation.

Description

technical field [0001] The invention provides a novel downcomer pyrolysis and liquefaction system of a ceramic heat storage ball circulating heating type, which belongs to the technical field of renewable energy utilization. Background technique [0002] Liquid fuel is an indispensable key energy product for social and economic development and people's life today. However, as the shortage of energy resources intensifies, the contradiction between demand and supply of liquid fuel becomes more prominent. At the same time, environmental pollution caused by excessive use of fossil fuels, especially urban smog, is getting worse. Compared with other renewable energy sources, biomass, as the only carbon-containing organic energy source, has the potential to replace petroleum on a large scale to produce liquid fuels and chemicals. my country is rich in biomass energy resources, and the development of high-end products such as biomass-based liquid fuels and chemicals that can replac...
