DETAILED DESCRIPTION

[0014] The present invention is described in detail below in conjunction with the accompanying drawings: Example 1 like Figure 1As shown, a nickel reverberatory furnace combustion device comprises a burner brick 1, which is a burner brick for an existing conventional nickel reverberatory furnace. A first oxygen delivery pipe 2 penetrating the burner brick 1 is provided in the burner brick 1, and an oxygen outlet 3 is formed at one end of the first oxygen delivery pipe 2. Oxygen can be delivered to the nickel reverberatory furnace through the oxygen outlet 3. A sealing baffle 4 is provided at the other end of the first oxygen delivery pipe 2. A gas pipe 5 coaxially arranged with the first oxygen delivery pipe 2 is provided in the first oxygen delivery pipe 2. The gas pipe 5 passes through the sealing baffle 4. The gas pipe 5 can deliver gas to the nickel reverberatory furnace. The delivered gas is immediately fully mixed with oxygen at the oxygen outlet 3, thereby improving the combustion effect and the utilization rate of oxygen. The first oxygen delivery pipe 2 is inclined downward and forms an angle of 3-10 degrees with the horizontal plane, and a gas delivery pipe 6 is connected to the side wall of the first oxygen delivery pipe. The gas delivery pipe 6 is used to deliver oxygen to the first oxygen delivery pipe 2. A first flame detector 7 horizontally arranged and penetrating the burner brick 1 is provided in the burner brick 1. The first flame detector 7 is located at the burner brick 1 The lower part is arranged horizontally, and an electronic igniter 8 is installed on the first flame detector 7. The electronic igniter 8 is installed on the first flame detector 7 in an existing conventional manner. The flame in the nickel reverberatory furnace can be detected and ignited by the first flame detector 7 and the electronic igniter 8. A second oxygen delivery pipe 9 is provided in the burner brick 1 and passes through the burner brick 1. The second oxygen delivery pipe 9 is located at the upper part of the burner brick 1. The second oxygen delivery pipe 9 and the first oxygen delivery pipe 2 are arranged parallel to each other. The second oxygen delivery pipe 9 can transport oxygen to the reverberatory furnace, thereby increasing the oxygen content in the reverberatory furnace and further improving the combustion effect. In addition, a second flame detector 10 is also provided in the burner brick 1 and passes through the burner brick 1. The second flame detector 10 is located between the first oxygen delivery pipe 2 and the second oxygen delivery pipe and is arranged parallel to the first oxygen delivery pipe 2. In addition, the first oxygen delivery pipe 2, the second oxygen delivery pipe 9, the first flame detector 7 and the second flame detector 10 are located in the same vertical plane.

[0015] Example 2 A nickel reverberatory furnace combustion method, using the above-mentioned nickel reverberatory furnace combustion device, comprises the following steps: (1) First, oxygen is input into the reverberatory furnace through the first oxygen delivery pipe 2 and the second oxygen delivery pipe 9, and the oxygen pressure in the first oxygen delivery pipe 2 and the second oxygen delivery pipe 9 is adjusted so that the oxygen pressure in the first oxygen delivery pipe 2 and the second oxygen delivery pipe 9 is between 50KPa and 0.6MPa. By setting the corresponding pressure and ensuring the speed of oxygen ejection, the oxygen is dispersed in the reverberatory furnace together with the oxygen. At the same time, the oxygen supply in the first oxygen delivery pipe 2 and the second oxygen delivery pipe 9 is adjusted so that the oxygen supply in the first oxygen delivery pipe 2 is 20% of the total oxygen supply, and the oxygen supply in the second oxygen delivery pipe 9 is 80% of the total oxygen supply. Since the second oxygen delivery pipe 9 is inclined downward, the oxygen input into the reverberatory furnace by the second oxygen delivery pipe 9 can be fully dispersed in the reverberatory furnace, ensuring that the fuel gas in various parts of the reverberatory furnace is fully burned. Since the oxygen input into the reverberatory furnace by the first oxygen delivery pipe 2 can be immediately mixed with the fuel gas, the ignition success rate can be effectively improved.

[0016] (2) Gas is input into the reverberatory furnace through the gas pipe 5. In this embodiment, natural gas or coal gas can be used for the gas, and the electronic igniter 8 is used for ignition. Since the first oxygen delivery pipe 2 and the second oxygen delivery pipe 9 are inclined downward, the input gas is ejected downward and can be quickly ignited by the electronic igniter 8 below. The ignition success rate is high. When the gas is burned in the reverberatory furnace, it is mixed with the oxygen input from the second oxygen delivery pipe 9, and the combustion effect is good. During the combustion process, the first flame detector 7 and the second flame detector 10 are used to detect the combustion condition in the furnace. The detection result is more accurate and can effectively prevent false detection. When the flame in the reverberatory furnace is extinguished, the delivery of oxygen and gas can be stopped immediately.
