Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-purity sulfur preparation, and particularly relates to a sulfur incinerator based on high-purity sulfur preparation. BACKGROUND

[0002] The sulfur incinerator based on high-purity sulfur preparation is a core equipment in a modern large-scale sulfuric acid production device, and is designed to efficiently, stably and completely burn liquid high-purity sulfur to generate high-concentration sulfur dioxide furnace gas which is a key raw material required in a subsequent acid production process. Since high-purity sulfur (with extremely low impurity content) is used as fuel, the sulfur incinerator can realize a very clean combustion process, effectively avoids problems such as furnace body corrosion, catalyst poisoning and pipeline blockage caused by impurities (such as ash, arsenic, selenium, etc.), and ensures the concentration and stability of the sulfur dioxide gas by precisely controlling the combustion conditions (such as temperature and air distribution), thereby laying a solid foundation for the downstream conversion and absorption processes and ultimately ensuring the safe and stable operation of the entire sulfuric acid production system for a long period, high efficiency and low emission.

[0003] For example, the prior art patent No. CN201921438595.3 discloses a sulfur incinerator, which comprises a sulfur incinerator body, a feeding device fixedly connected to the sulfur incinerator body, the feeding device comprising a feeding hopper and a crushing cavity, a rectangular pipe communicated with the upper side of the crushing cavity, the free end of the rectangular pipe being communicated with the feeding hopper, and a valve provided in the rectangular pipe for controlling the communication state of the rectangular pipe; and an airflow channel communicated with the crushing cavity and having a free end communicated with the sulfur incinerator body. The present scheme can solve the technical problem that the solid sulfur cannot be completely burned in the prior art, thereby requiring additional energy consumption to melt the sulfur into a liquid state.

[0004] In the combustion process before the preparation of high-purity sulfur, it is necessary to ensure that the concentration of hydrogen sulfide raw material in the combustion furnace is maintained within a certain range, otherwise insufficient or excessive combustion will occur, both of which will result in the failure to produce sulfur. Therefore, it is necessary to ensure the concentration of hydrogen sulfide in the combustion furnace, but the existing combustion furnace cannot accurately measure the concentration of hydrogen sulfide raw material.
