according to the sulfur incinerator for the electronic grade sulfuric acid preparation, most of air conveyed by the air conveying pump 301 firstly collides with the left side of the air guide body 304, the air can move upwards in the hearth 1 under the action of the inclined surface of the air guide body 304 so as to react with sulfur solution sprayed by the spraying assembly 2, further air collides with the upper wall of the inner cavity of the hearth 1 and then moves downwards in the inner cavity of the hearth 1 so as to reciprocate, namely, the air entering the hearth 1 from the air inlet 302 can be stirred through the air disturbance assembly 3, and the disturbance air can drive the sulfur solution mixed with sulfur matters to rise, so that the boiling time, namely the burning time, of the mixed sulfur matters in the hearth 1 is prolonged, the burning rate of the mixed sulfur matters is improved, the quantity of the dropped mixed sulfur matters is reduced, and the sulfur incinerator is quite beneficial;
in the sulfur incinerator for the electronic grade sulfuric acid preparation, most of air which is conveyed into the hearth 1 from the air inlet 302 and impacts the left side of the air guide body 304, and a small part of air passes through the through groove 306, oxygen is conveyed to the top end of the through groove 306 by the oxygen supplementing pipe 303 in the whole working reaction process, and in the process, the air passing through the through groove 306 can assist the oxygen conveyed into the hearth 1 from the oxygen supplementing pipe 303 to upwards generate air flow circulation, so that the oxygen content in the hearth 1 is improved, and the combustion rate of mixed sulfur-containing substances is further improved;
this electronic grade sulfuric acid preparation is with burning sulphur stove, owing to offer jack 305 on the air guide body 304, through the height of adjustable air guide body 304 in furnace 1 inner chamber of grafting of different jacks 305 and oxygenating pipe 303 to this can indirectly cause the influence of certain direction to the air that comes from air inlet 302, thereby change the inside air cycle of furnace 1, with this cooperation spray assembly 2 carries out further interdynamic to the sulphur solution of blowout, can also change the reaction degree of sulphur and air to a certain extent.
