Abstract
The invention relates to a multi-step chlorine dioxide generator, which comprises discharging pipes, a vacuum pump and three reaction vessels. Each of the three reaction vessels is provided with a solid feeding system, an air inlet pipe, an overflow pipe and a draining pipe. Overflow pipes, draining pipes, air inlet pipes and the discharging pipe of neighboring reaction vessels are communicated with each other. The discharging pipe is connected to the vacuum pump. The first reaction vessel is provided with a liquid feeding metering pump and a raw material storage groove. The third reaction vessel is provided with a heating device and a pressure balancing pipe. The generator of the invention avoids instantaneous generation of high concentration chlorine dioxide and a lot of reaction heat resulted from adding of sufficient amounts of a hydrogen peroxide sulfuric acid solution and solid sodium chlorate into a reaction vessel at one time, and also avoids the defect of inadequate reaction. As reaction heat exists in each reaction vessel, heat energy consumption is substantially reduced. Also, the generator provided in the invention has high working efficiency, and a raw material conversion rate greater than 95%.
