Novel hydrogen chloride synthesis furnace

The novel hydrogen chloride synthesis furnace comprises a first furnace body, a second furnace body, a third furnace body and a furnace bottom, and a combustion part is arranged in the first furnace body; the lower end of the first furnace body is sequentially connected with the second furnace body, the third furnace body and the furnace bottom through bolts; a vortex device is arranged in the upper end of the first furnace body; three baffle plates are arranged on each of two side walls in the second furnace body in a mutually crossed manner; a graphite block A, a graphite block B, a graphite block C, a graphite block D, a graphite block E and a graphite block F are arranged in the third furnace body from top to bottom. The device effectively improves the equipment operation cycle, linearly reduces the maintenance frequency, and reduces the maintenance cost and spare part loss cost. According to the device, the graphite block is effectively prevented from being scoured, corroded and cracked; the operation cy
