Device and method for cracking boron trifluoride complex

Abstract

The present disclosure relates to the technical field of separation of boron isotopes, in particular to a device and method for cracking a boron trifluoride complex. The device for cracking the boron trifluoride complex includes a continuous feeding system, a rising film preheater, a falling film preheater, a boron trifluoride gas circulation pipeline, a separation chamber, a cracking tower, a gas-liquid separator, an impurity removal tower, and anisole storage tank. By employing a continuous feeding method, the device for cracking boron trifluoride complex shortens retention time of anisole at a high-temperature stage while ensuring a cracking rate of a boron trifluoride-anisole complex, reduces the thermal decomposition degree of anisole, maintains the purity of anisole, and greatly improves the utilization rate and production safety of anisole, thus ensuring continuous and stable production.
