The invention provides a drying stirrer for silicon tetrachloride slag slurry in a cold hydrogenation technology. The drying stirrer comprises a shell, a stirring shaft and a transmission device. A drying cavity is defined by the shell. The shell is provided with a feeding port and a discharging port. The stirring shaft is horizontally arranged in the drying cavity and comprises a shaft head and a hollow shaft tube, wherein the shaft head and the hollow shaft tube are welded together. The hollow shaft tube is provided with stirring blades. A first helical band and a second helical band are fixed to the hollow shaft tube through supporting rods and are wound around the periphery of the hollow shaft tube. The respective spiral directions, on the left side and the right side of the hollow shaft tube, of the first helical band and the second helical band are opposite, and the spiral directions of the first helical band and the second helical band are opposite. Under rotation of the stirring shaft, the first helical band enables the slurry to move from the two sides to the middle, and the second helical band enables the slurry to move from the middle to the two sides. The drying stirrer enables the slurry to flow circularly, and the slurry is stirred more evenly. The invention further provides a treatment system and method for the silicon tetrachloride slag slurry.

The invention provides hexagonal or octagonal tangential arrangement of anthracite burning single-fireball direct-flow combustors, which is characterized in that: two groups of combustors are arranged on each water-cooling wall or two groups of combustors are arranged on two opposite water-cooling walls of a hearth respectively and a group of combustors are arranged on the other two opposite water-cooling walls respectively, each group of combustors are at least divided into a small group; and each small group of combustors are vertically provided with at least two primary air pulverized nozzles and three secondary air pulverized nozzles at intervals. Each coal mill is connected with eight or six primary air pulverized nozzles which have the same level with that of the coal mill. The start and stop of each coal mill affect the running of the eight or six primary air pulverized nozzles which are on the same layer. The hexagonal or octagonal tangential arrangement of the anthracite burning single-fireball direct-flow combustors can decrease the number of the air pulverized nozzles in a single group of combustors on the premise of meeting the requirements of the thermal power of a single air pulverized nozzle and the number of the total air pulverized nozzles, allows the thermal load qHr of a wall in a combustor area to be relatively high, and guarantees the timely ignition of an pulverized anthracite flow and low-load combustion of a boiler without oil.
