Gas-solid/gas-gas phase plasma tubular reactor process and device

Abstract

The invention relates to a gas-solid / gas-gas phase plasma tubular reactor process and device, which comprises a circulating booster fan, a reaction gas tank, an auxiliary gas tank, a reaction powder device, a reaction powder intermediate bin, a plasma tubular reactor, a gas-solid separation device, an after-reaction powder intermediate bin, an after-reaction powder conveying device, an after-reaction powder pretreatment device, a product tank and an after-reaction gas treatment device which are communicated in turn. A reaction gas, an auxiliary gas and a solid substance are mixed by the booster fan and then conveyed to the plasma tubular reactor for reaction, the gas phase is recycled by gas-solid separation, and the impurities are discharged and treated; the completely reacted solid phase is conveyed to the product system, and the incompletely reacted solid phase is used for circulating reaction; and the device solves the problems of high cost, complex process and environmental pollution of the conventional process and easy adhesion and accumulation of the solid substance in the reactor, poor product quality, reaction discontinuity and the like in the plasma technology, and can be applied in the chemical chlorination process.

Description
