Description

Technical Field

[0001] The utility model relates to a multi-nozzle sulfur recovery and sulfur production system, belonging to the technical field of sulfur preparation. Background Art

[0002] The technological development and market prospects of sulfur recovery processes have attracted considerable attention. As a key chemical raw material, sulfur recovery and utilization have significant economic and environmental implications. With increasing global demand for efficient resource utilization and growing awareness of environmental protection, sulfur recovery processes have experienced rapid development. Existing sulfur preparation technologies utilizing a single burner have limitations. At high sulfur recovery loads, particularly when using high-sulfur coal, acid gas and oxygen cannot fully contact and react, increasing the operational complexity of subsequent systems and leading to the risk of exceeding environmental standards for exhaust gas emissions, resulting in substandard emissions.

[0003] Therefore, we proposed a multi-nozzle sulfur recovery and sulfur production system. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-nozzle sulfur recovery and sulfur production system, which not only improves the sulfur conversion rate of the sulfur production furnace and reduces the environmental protection emission data of the tail gas, but also can increase the production capacity of the sulfur recovery device and increase the stability of the operation of the sulfur recovery device.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a multi-nozzle sulfur recovery and sulfur-making system, including a sulfur-making furnace, the inner cavity of the sulfur-making furnace is provided with a gasification chamber and a radiation waste pot in sequence from top to bottom, the side wall of the gasification chamber is provided with a burner, the number of the burners is an even number, and the burners are symmetrically distributed on both sides of the gasification chamber. The symmetrical arrangement of multiple burners can not only increase the residence time of the reaction gas in the furnace, but also allow the acid gas and oxygen to have sufficient contact, and under high-load conditions, hydrogen sulfide and oxygen can be completely burned, thereby improving the sulfur recovery efficiency. It is also an effective method to solve the current high-sulfur coal high load leading to high sulfur dioxide in tail gas. The inner side wall of the sulfur-making furnace located at the gasification chamber is provided with a water-cooled wall, the burner is arranged to penetrate the water-cooled wall, and the side wall of the burner is tightly fitted with the water-cooled wall, which can not only protect the furnace body and the burner, but also recover heat.

[0006] The aforementioned multi-nozzle sulfur recovery and sulfur production system has two burners arranged on the side wall of the sulfur production furnace. A flame detector can be set on the top of the sulfur production furnace to improve the accuracy of flame detection.

[0007] The aforementioned multi-nozzle sulfur recovery and sulfur production system has four burners arranged on the side wall of the sulfur production furnace. A flame detector can be set on the top of the sulfur production furnace to improve the accuracy of flame detection.

[0008] The aforementioned multi-nozzle sulfur recovery and sulfur production system also includes a steam drum, which is connected to the radiation waste boiler through a pipeline to form a circulation loop. The steam drum provides boiler water for the radiation waste boiler and recovers its heat energy to generate steam.

[0009] In the aforementioned multi-nozzle sulfur recovery and sulfur production system, the steam drum is connected to the water-cooled wall through a pipeline to form a circulation loop. The steam drum provides boiler water to the water-cooled wall and recovers its heat energy to generate steam.

[0010] The aforementioned multi-nozzle sulfur recovery and sulfur production system further includes a separation tank, the output end of the separation tank is connected to the preheater refrigerant input end, and the preheater refrigerant output end is connected to the burner.

[0011] In the aforementioned multi-nozzle sulfur recovery and sulfur production system, the steam output port of the steam drum is connected to the heat medium input end of the preheater.

[0012] In the aforementioned multi-nozzle sulfur recovery and sulfur production system, the heating surface of the water-cooled wall is coated with a refractory lining.

[0013] Compared with the prior art, the burner arrangement of the utility model is reasonable. By setting one burner to two or four, the residence time of the reaction gas in the furnace can be increased, and the acid gas and oxygen can be fully contacted. Under high-load conditions, hydrogen sulfide and oxygen can be completely burned, thereby improving the sulfur recovery efficiency. At the same time, multiple sulfur-making burners are arranged on the side of the sulfur-making furnace, so that a flame detector can be set on the top of the sulfur-making furnace, thereby improving the accuracy of flame detection. The multi-nozzle sulfur recovery system of the utility model not only improves the sulfur conversion rate of the sulfur-making furnace and reduces the exhaust gas environmental protection emission data, but also can improve the production capacity of the sulfur recovery device and increase the stability of the operation of the sulfur recovery device.
