Novel chlorination furnace circulating fluidization system

Abstract

The invention provides a novel chlorination furnace circulating fluidization system. A discharging opening of a petroleum coke raw material tank is connected with a discharging pipe in parallel and then is connected with a lower inlet of a chlorination furnace; a plurality of chlorine gas inlets and a dreg discharging opening are further formed in the bottom of the chlorination furnace; the plurality of chlorine gas inlets are connected with a chlorine gas pipe; the dreg discharging opening is connected with a dreg discharging pipe; an outlet is formed in the top of the chlorination furnace; the outlet is connected with a side part inlet of a high-temperature cyclone separator through a feeding pipe; a liquid discharging opening is further formed in the top of the high-temperature cycloneseparator; the liquid discharging pipe is connected with the top of a low-temperature cyclone separator through a liquid discharging pipe; a liquid outlet is further formed in the top of the low-temperature cyclone separator. The novel chlorination furnace circulating fluidization system provided by the invention has the characteristics of compact structure, convenience for installation, stabilityin operation, safety and environment protection and the like. The whole reaction system has a circulating fluidization function and the dreg discharging pipe is not blocked; the high-temperature cyclone separator and the low-temperature cyclone separator are matched to use, so that a plurality of times of circulation, repeated combustion and reaction of a titanium tetrachloride mixed solution areensured.

Description

technical field [0001] The invention relates to a circulating fluidized bed combustion technology, in particular to a novel chlorination furnace circulating fluidized system. Background technique [0002] Circulating fluidized bed combustion technology is the core of clean coal combustion power generation technology. In recent years, circulating fluidized bed boilers have been rapidly promoted and developed in domestic and foreign power generation industries due to their excellent environmental protection performance, superior peak-shaving economy, good coal type adaptability and high-efficiency inferior fuel combustion. At present, circulating fluidized bed boilers with a capacity of 220t / h and below have been widely promoted in China, and 410t / h circulating fluidized bed boilers have also begun to be put into commercial operation. The 300MW circulating fluidized bed boiler demonstration project is in Sichuan Baima Power Plant It has been successfully operated, and the sup...

Problems solved by technology

Due to the instability of titanium tetrachloride, it is difficult to isolate from the outside world during the separation process

When air enters, titanium tetrachloride will generate corrosive hydrogen chloride in contact with air, which not only consumes titanium tetrachloride materials, but also has a huge impact on separation equipment and staff, and seriously pollutes the environment
