RICE HULL COMBUSTION APPARATUS CAPABLE OF CONTINUOUSLY PRODUCING AMORPHOUS NANO-SIO2 BY WATER COOLING TEMPERATURE CONTROL

WIPO Patent Application WO/2020/133476

A1

A rice hull combustion apparatus capable of continuously producing amorphous nano-SiO 2 by water cooling temperature control. The apparatus improves a heating component and a heat exchange system (5), i.e., the heating component is arranged as a plurality of heating elements (4), and a water pipe playing a role of heat exchange in the heat exchange system is arranged as a multi-bent water delivery pipe (52). According to the rice hull combustion apparatus, by improving the heating elements (4) and the multi-bent water delivery pipe (52), the internal temperature of the rice hulls can be maintained not to be greater than 600ºC for a long time, the temperature of all positions in the rice hulls is proximate, thus the local high temperature phenomenon is avoided; the production of the amorphous SiO 2 is improved; at the same time, the heat generated by the combustion of the rice hulls is sufficiently absorbed and utilized; and the utilization rate of the heat energy is improved. Furthermore, according to the apparatus, a temperature control system (8), a pressurization pump, and a heating element control switch are improved, so that the internal temperature of the rice hulls can be monitored online in real time, and the problems such as the excessively high internal temperature and local temperature of the rice hulls are solved.
