Semi-continuous anti-blocking subcritical/supercritical reaction heating device

Abstract

The invention discloses a semi-continuous anti-blocking subcritical / supercritical reaction heating device. The device comprises a furnace body, a first supporting plate, a second supporting plate anda third supporting plate are sequentially arranged in the furnace body from top to bottom, three grooves are respectively arranged in the long side surfaces, at the same side, of the first supportingplate, the second supporting plate and the third supporting plate, and thee lifting rods rotate to screw inserting pieces into the grooves in order to complete vertical movement of the first supporting plate, the second supporting plate and the third supporting plate and realize continuous transmission of a reaction kettle in the heating furnace, and the device can be manually operated. Compared with heating devices in the prior art, the semi-continuous anti-blocking subcritical / supercritical reaction heating device of the invention can treat mixed or independent biomass with various concentrations, makes the reaction kettle filled with raw materials to realize approximately continuous feeding and discharging, and reduces the size of the large reaction kettle to meet the requirements of the large reaction kettle for the thickness and the strength of the raw materials.

Description

technical field [0001] The invention relates to a semi-continuous anti-blocking sub / supercritical reaction heating device, which belongs to the technical field of sub / supercritical conversion. Background technique [0002] Sub- / supercritical biomass conversion can be divided into gasification, liquefaction and carbonization according to different reaction conditions, and can be used for the conversion of wet biomass. Generally, high temperature and high pressure reaction conditions are required. In the case of relatively low temperature and pressure (below 350°C), it is often used to make biochar and bio-oil, known as hydrothermal carbonization and hydrothermal liquefaction, and higher temperature and pressure are used for supercritical water gasification. [0003] The current sub / supercritical reactors are mainly divided into two types: continuous reactors and batch reactors. Continuous reactors are often blocked, especially for high-concentration biomass, and generally h...

AI Technical Summary

Problems solved by technology

Continuous reactors are often blocked, especially for high-concentration biomass, and generally high-concentration biomass has a high carbon production rate, so it is not suitable for continuous reactors.

[0004] Batch reactors are relatively inefficient and are mainly used in laboratories

Due to the requirement of high pressure on the reactor, the current reaction device cannot be made very large, which reduces the adaptability of the reactor
