Multi-chamber rotational-flow stepped high-efficiency heat exchanging system of rotary pyrolyzing furnace

Abstract

The invention provides a multi-chamber rotational-flow stepped high-efficiency heat exchanging system of a rotary pyrolyzing furnace. The multi-chamber rotational-flow stepped high-efficiency heat exchanging system comprises a heating chamber, wherein the heating chamber is divided by a separation plate into two or more heating chambers, the bottoms of two adjacent heating chambers are provided with a hot gas outlet communicating the two heating chambers, and a plurality of fins arranged in an annular shape are arranged in the heating chamber. By adopting the multi-chamber rotational-flow stepped high-efficiency heat exchanging system, the heating process is processed in a sectional manner by virtue of various chambers on the basis of external heating way, so that the remaining time and route of the heated gas in the chamber can be manually increased, the heated gas performs sufficiently heat exchange with a tube wall wraping biomass, the stable and sufficient heating is realized, and the utilization rate of energy is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural design, in particular to a rotary pyrolysis furnace equipment, specifically a multi-chamber swirling cascade high-efficiency heat exchange system for a rotary pyrolysis furnace. Background technique [0002] Through technical retrieval, the Chinese patent application number is 201410348013.8, and the name is a continuous integral pyrolysis furnace for biomass. The continuous integral pyrolysis furnace for biomass includes a thermal insulation shell and a flue gas heating chamber. There is a pyrolysis chamber in the cavity, and the feature is that a pyrolysis gas tar cracking chamber and a semi-coke calcination chamber are also provided in the flue gas heating chamber, and the pyrolysis chamber, pyrolysis gas tar cracking chamber and semi-coke calcination The chambers are placed vertically in the flue gas heating chamber, and pass through the spiral hot air channel, and the upper and lower end...

AI Technical Summary

Problems solved by technology

[0004] Based on the analysis of the above patent documents and the existing technologies, the biomass continuous pyrolysis equipment needs to heat, pyrolyze and carbonize the biomass in the process of processing rural energy. Common heating methods include internal heating and external heating. , both have their own advantages, but there are problems of uneven heat exchange, insufficient heating and stable heating, and low energy utilization.
