Pyrolysis and liquidation system for heating biomass by using solid heat storage ball

Abstract

The invention provides a pyrolysis and liquidation system for heating biomass by using a solid heat storage ball. In the system, an outlet of a heat storage ball heating device is communicated with a feed inlet of a reactor through a feeding device; a feed outlet of the reactor is communicated with a separation device; the bottom of the separation device is connected with an ash box, and the top of the separation device is connected with a pyrolysis gas treatment device; and a second heat storage ball outlet on the side wall at the lower end of the separation device is connected with the heat storage ball heating device through a heat storage ball lifting device. The system is characterized in that: the reactor is a sleeve-type reactor and comprises an inner pipe and an outer pipe which are coaxially sleeved with each other; the two ends of the inner pipe are communicated with the feeding device and the separation device respectively; a hot air outlet and a hot air inlet of the outer pipe are communicated with the heat storage ball heating device respectively; the separation device comprises a separation box and a sieve plate which is obliquely arranged in the separation box and is tilted along the direction of an outlet at the bottom of the inner pipe; and the lower end of the sieve plate is connected with the outlet of the second heat storage ball, and the upper end of the sieve plate and the side wall of the separation box forms a carbon ash falling opening. The device reduces energy consumption and has high continuous operation capability, high liquid conversion rate and high working performance.

Description

technical field [0001] The invention provides a solid heat storage ball heating biomass pyrolysis liquefaction system, which belongs to the technical field of renewable energy utilization. Background technique [0002] With the rapid development of my country's economy and society, the consumption of oil resources is also increasing rapidly, and the dependence on foreign oil is getting higher and higher. At the same time, the greenhouse effect and environmental pollution caused by the extensive use of fossil fuels are becoming more and more serious. Biomass pyrolysis and liquefaction is one of the ways to effectively utilize biomass energy. The bio-oil produced by it can be directly used as fuel oil in boilers and other combustion equipment, and can also be used in internal combustion engines instead of diesel and gasoline after catalytic hydrogenation and other improved treatments. Extract specialty or high value-added chemicals. Therefore, the promotion and application o...
