The liquid sulfur has a tendency to fall under the influence of gravity after being ejected from the liquid sulfur atomizing spray gun 3, so that when the liquid sulfur impacts the position of the trapezoid support seat 7, the liquid sulfur is distributed more at the lower position, and for this purpose, the trapezoid support seat 7 with the upper narrow and the lower wide is used as the support of each strip-shaped plate 10 with the length gradually increasing from top to bottom, thereby better receiving the liquid sulfur spray.
In this embodiment: the bottom end surface of the furnace chamber 2 is an inclined surface, and the horizontal height of the inclined surface at the bottom of the furnace chamber 2 is gradually reduced from two sides to the middle. This arrangement facilitates the smooth flow of the liquid sulfur falling to the bottom of the furnace chamber 2 into the bottom of the annular groove 6.

In this embodiment: the liquid sulfur atomizing spray gun 3 specifically comprises: the device comprises an atomizing pipe 303, a shrinkage pipe 305 and a conical spray head 306 which are sequentially and fixedly connected, wherein a buffer pipe 304 is fixedly connected between the atomizing pipe 303 and the shrinkage pipe 305, an air inlet pipe 302 is fixedly connected to the top end of the atomizing pipe 303, a liquid sulfur pipe 301 is inserted into one end of the atomizing pipe 303, the conical spray head 306 stretches into the furnace chamber 2 and faces the trapezoid supporting seat 7, an air homogenizing fan 308 is rotatably connected to one end of the inner portion of the conical spray head 306, and a plurality of evenly distributed air distributing holes 307 are formed in the inner wall of one side of the conical spray head 306. The liquid sulfur atomizing spray gun 3 can burn after the abundant mixing of liquid sulfur and air, can effectively promote raw materials utilization ratio to the spray width of spray gun is big, and the injection direction is fixed, can evenly spout into in the sulfur burning stove, can effectively prevent the condition that the oven is heated unevenly from taking place.
In this embodiment: the top end of the outer side surface of the furnace body 1 is fixedly connected with an ignition tube 5, and the bottom end of the ignition tube 5 extends into the furnace chamber 2 and is positioned on one side above the conical nozzle 306. The squib 5 is used to ignite a spray of liquid sulfur.
In this embodiment: the other side surface of the furnace body 1 is fixedly connected with an air outlet pipe 4 communicated with the furnace chamber 2. The air outlet pipe 4 is used for exhausting air.
The working principle of the application is as follows: when the liquid sulfur atomization device is used, firstly, ignition is carried out through the ignition tube 5, namely, a burnt cotton iron wire is led into the furnace body 1 from the ignition tube 5, then the liquid sulfur atomization spray gun 3 is opened, liquid sulfur is led into the atomization tube 303 through the liquid sulfur tube 301, then air is led into the atomization tube 303 through the air inlet tube 302, and the liquid sulfur and the air are fully mixed in the atomization tube 303 to form a vaporous mixed air flow. Then, the mixed air flow enters the shrinkage tube 305 after being buffered by the buffer tube 304, at this time, the flow channel of the mixed air flow is narrowed, the flow speed is increased, the air flow enters the conical nozzle 306 to drive the air homogenizing fan 308 to rotate, the air homogenizing fan 308 uniformly disperses the originally concentrated air flow, the air flow is led out uniformly from the air distribution holes 307, and the led air flow starts to burn to generate sulfur dioxide gas after contacting with the burnt cotton iron wires and is led out from the air outlet pipe 4.
In the process of burning sulfur, part of liquid sulfur falls to the bottom of the furnace chamber 2 under the action of gravity and cannot burn fully, part of liquid sulfur slowly flows into the annular groove 6 under the action of self gravity and is converged at the bottom of the annular groove 6, at the moment, the rotating motor 17 of the driving mechanism operates to drive the main gear 18 to rotate, the main gear 18 drives the auxiliary gear 14 to rotate through the chain 15, so that the rotating shaft 806 and the barrel 801 are driven to synchronously rotate, the two supporting frames 802 on the barrel 801 rotate in a following way, the rotating boxes 803 on the two supporting frames 802 also rotate in a following way, when the rotating boxes 803 rotate to the bottom of the annular groove 6, part of liquid sulfur is brought into the notch 804, at the moment, the refractory heat accumulator 805 in the notch 804 heats the liquid sulfur again, and in the notch 804 shakes left and right to accelerate the thermal reaction speed in the rotating process of the rotating boxes 803. It should be noted that, the amount of liquid sulfur carried up by the rotating box 803 is not large each time, so that the situation that excessive liquid sulfur in the notch 804 is not reacted is effectively avoided, and in addition, if the rotating box 803 rotates until the top end is not completely reacted, residual liquid sulfur flows out of the notch 804 and returns to the annular groove 6 again under the action of gravity to wait for the next reaction. Because the liquid raising component 8 in the furnace chamber 2, the trapezoid supporting seat 7, the strip-shaped plate 10 and the like are made of high-temperature alloy steel, the high-temperature alloy steel can resist 1500 ℃, in the sulfur burning process, the cylinder 801 and the two supporting frames 802 absorb heat to form a metal cage with higher temperature, and in the process of flowing out and descending liquid sulfur from the notch 804, the liquid sulfur passes through the metal cage, so that a certain heating effect is also achieved on the fallen liquid sulfur, and the combustion efficiency is further improved.
In addition, since the liquid sulfur tends to fall under the influence of gravity after being discharged from the liquid sulfur atomizing lance 3, when the liquid sulfur spray impinges on the position of the trapezoidal support seat 7, the amount of liquid sulfur distributed at the lower position is larger, and for this purpose, the trapezoidal support seat 7 with the upper narrow and lower wide is adopted as the support of each strip-shaped plate 10 with the length gradually increasing from top to bottom, thereby better receiving the liquid sulfur spray. Next, the triangular cutting 11 cuts the sprayed liquid sulfur spray to split, the split liquid sulfur spray is sprayed on the arc-shaped surface A12, not only is buffered, but also the descending trend of the liquid sulfur can be delayed to enable the liquid sulfur to burn more fully, the inclined surface B19 is used for conveying the liquid sulfur which is not fully burnt downwards layer by layer, and finally, the liquid sulfur falling on the bottom of the furnace chamber 2 can flow into the annular groove 6 from the two sides of the through groove 9 or the trapezoid supporting seat 7.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present application without departing from the spirit or scope of the application.
