Problems solved by technology

There are following problems in this ignition method: 1, it takes a long time, it takes a long time from ignition to sulfur stable combustion, the ignition process is difficult to control, and the labor intensity is high, 2, more sulfur trioxide will be produced simultaneously during ignition, which It will increase the fouling of equipment pipelines; 3. On the other hand, because this ignition method requires manual operation, it will also bring unsafe factors
But the production SO 2 The structure of the gas device is slightly complicated, and there are many input pipes. This ignition method needs to be used in conjunction with external hot air heating equipment, which increases the process and cost

Embodiment 1

[0024] An auxiliary device for ignition of a sulfur burning furnace, such as Picture 1-1 As shown, the device includes a sulfur gasification chamber 2 composed of a vertical cylindrical airtight container. The lower part of the sulfur gasification chamber is equipped with a high-temperature gaseous sulfur outlet pipe 1, and the upper part of the sulfur gasification chamber is equipped with a pipe for sending sulfur into the sulfur gasification chamber. The sulfur inlet pipe 5, the inside of the sulfur gasification chamber is equipped with a heat storage body, the temperature of the heat storage body is above 250°C, Picture 1-1 The heat accumulator in is 3 installed on the end plate 4, 3 heat accumulator pipes 31 arranged in a line (see Figure 1-2 ); the sulfur input from the sulfur gasification chamber upper sulfur inlet pipe 5 can be solid sulfur, liquid sulfur or gaseous sulfur or a mixture of solid sulfur, liquid sulfur or gaseous sulfur and air;

Embodiment 2

[0030] A method for igniting a sulfur-burning furnace. It is a method of sulfur ignition using the ignition auxiliary device of the sulfur-burning furnace described in Embodiment 1 of the present invention. It is through passing sulfur and its mixture into the auxiliary ignition device of the sulfur-burning furnace, and the regenerator heated to above 250°C in advance. It is contacted and heated to become gaseous sulfur whose temperature reaches the ignition point temperature, and then the gaseous sulfur is passed into the air-filled sulfur furnace and ignites itself when it encounters air, so as to achieve the purpose of ignition.

[0031] The sulfur and its mixture are solid sulfur, liquid sulfur or gaseous sulfur or the mixture of solid sulfur, liquid sulfur or gaseous sulfur and air.

[0032] The regenerator in the sulfur gasification chamber 2 of the ignition auxiliary device of the sulfur-burning furnace can be the heat storage tube 31 installed on the end plate 4 as des...

Abstract

The invention relates to an ignition assisting device of a sulfur burner, which comprises a sulfur gasification chamber formed from a cylindrical closed container, wherein a heat accumulator with the temperature of more than 250 DEG C is installed inside the sulfur gasification chamber, a sulfur inlet pipe for introducing solid sulfur, liquid sulfur or gaseous sulfur or the mixture of the solid sulfur, the liquid sulfur or the gaseous sulfur and air into the sulfur gasification chamber is arranged at the upper part of the sulfur gasification chamber, and a high-temperature gaseous-sulfur outlet pipe is installed at the lower part of the sulfur gasification chamber; and the heat accumulator in the sulfur gasification chamber can be a heat storage pipe or a barrel-shaped heat accumulator and also can be a heat storage material lined on the inner wall of the container of the sulfur gasification chamber. An ignition method of the sulfur burner comprises the following steps of: introducingthe sulfur into the ignition assisting device of the sulfur burner to be contacted with the heat storage material preheated to the temperature of more than 250 DEG C and heated into the gaseous sulfur with the temperature reaching the ignition temperature, and then introducing the gaseous sulfur into the sulfur gasification chamber with the air to be self-ignited after being exposed to the air toachieve the purpose of ignition. The device has the advantages of simple structure, safe ignition method, economy and practicality.

Description

【Technical field】 [0001] The invention relates to a device and method for producing sulfur dioxide gas. In particular, it relates to a kind of SO 2 The utility model relates to an ignition auxiliary device and an ignition method for a gas sulfur-burning furnace. 【Background technique】 [0002] SO 2 It is an important auxiliary raw material in the sugar production process, and SO used in sugar factories 2 At present, they are all obtained by burning sulfur in a sulfur-burning furnace. However, the ignition of the current sulfur-burning furnace is mainly artificial, that is, first burning gasoline or firewood in a sulfur-burning furnace, and then adding solid or liquid Sulfur, or adding gasoline or firewood to the sulfur gasification chamber in the presence of sulfur for combustion, so that the sulfur can be ignited. There are following problems in this ignition method: 1, it takes a long time, it takes a long time from ignition to sulfur stable combustion, the ignition pr...
