TECHNICAL FIELD

[0001] The present application relates to the technical field of sulfur recovery, in particular to a sulfur recovery device and a recovery method thereof. BACKGROUND

[0002] In the process of industrial production, a large amount of sulfur-containing waste gas will be generated in many industries such as chemical industry, energy industry, metallurgy industry, etc. The sulfur elements in these waste gases mainly exist in the form of sulfur dioxide (SO2) and other forms. Sulfur dioxide is a harmful gas, which not only causes serious pollution to the atmospheric environment, triggers environmental problems such as acid rain, and endangers the ecological balance and human health, but also causes waste of sulfur resources. Therefore, it has important environmental protection and economic significance to carry out sulfur recovery treatment on sulfur-containing waste gas.

[0003] At present, there are various sulfur recovery devices on the market, but these devices still have some problems in actual application. On the one hand, in the process of sulfur recovery, in order to make the sulfur-containing gas fully react with the desulfurizing agent, a spraying mechanism is usually used to atomize and spray the desulfurizing agent into the reaction box. However, the particles in the air and the tiny particles generated in the reaction process may adhere to the pores of the spraying mechanism, causing the pores to be blocked, affecting the spraying effect of the desulfurizing agent, and thus reducing the efficiency and quality of sulfur recovery. On the other hand, during the process of sulfur desulfurization, a mixture of solid and water is generated, and the existing devices often have difficulty in achieving efficient solid-liquid separation when treating these mixtures, resulting in the mixture of solid and liquid, increasing the difficulty and cost of subsequent treatment, and being not conducive to further recycling of resources.
