Technical Field

[0001] This utility model relates to the field of reactor burner technology, specifically a circular furnace top burner. Background Technology

[0002] The Mannheim reactor uses sulfuric acid and potassium chloride as raw materials to produce potassium sulfate through heating and stirring within the furnace body. Generally, the upper layer is the combustion chamber, constructed of high-alumina refractory bricks and silicon carbide, and heated by two sets of burners; the middle layer is the reaction chamber; and the bottom layer is the flue, constructed of ordinary clay bricks.

[0003] An existing reaction furnace, such as the one named in announcement number CN211338826U, is a potassium sulfate reaction furnace, belonging to the technical field of potassium sulfate reaction furnaces. It includes a furnace bottom platform, a furnace body is set on the furnace bottom platform, a reaction chamber is set in the furnace body, and a heating device is embedded in the top of the reaction chamber; this reaction furnace adopts an electric heating device.

[0004] However, existing burners consist of two combustion nozzles, which can easily lead to uneven heating, causing local overheating, furnace collapse, and incomplete reaction. Therefore, we propose a circular furnace top burner to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a circular furnace top burner to solve the problems mentioned in the background art, which are that the existing burners consist of two combustion nozzles, which easily lead to uneven heating, local overheating, furnace collapse, and insufficient reaction.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a circular furnace top burner, comprising a first combustion control station and a second combustion control station. Both the first and second combustion control stations include a control box, a gas main pipe, and a hot air main pipe. The control box is connected to the gas main pipe and the hot air main pipe via a support frame. Hot air ring pipes are installed at the ends of both gas main pipes, and the two hot air ring pipes are stacked. Gas ring pipes are also installed at the ends of both gas main pipes, and the two gas ring pipes are stacked. Burners are arranged below the gas ring pipes, and twelve burners are provided.

[0007] Preferably, the twelve burners are divided into two groups, each group consisting of six burners, and the two groups of burners are arranged in a ring-shaped interval.

[0008] Preferably, a gas connector is provided on one side of the burner, and the burner is connected to a gas ring pipe through the gas connector. A hot air connector is provided on the other side of the burner, and the burner is connected to a hot air ring pipe through the hot air connector.

[0009] Preferably, the gas ring pipe and hot air ring pipe connected to the two sets of burners are respectively connected to the first combustion control station and the second combustion control station.

[0010] Preferably, both the hot air main pipe and the hot air ring pipe are DN series fittings, and both the gas main pipe and the gas ring pipe are DN series fittings.

[0011] Preferably, the burner is inclined toward the furnace reaction chamber.

[0012] Preferably, the input terminal of the control box is electrically connected to a flare detector. There are twelve flare detectors installed inside the furnace body and facing the burner.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The burner of this utility model abandons the original dual-nozzle mode. Its nozzles are distributed in a ring along the furnace. Twelve burners are distributed at equal intervals around the furnace body. The ring distribution structure makes the temperature distribution in the furnace space highly uniform, eliminating the temperature difference of local hot spots. The burners are installed at a certain angle, which can provide rotating hot airflow to create a better thermal balance in the combustion chamber and reduce the overheating of some silicon carbide bricks. This solves the problem that the existing burners are composed of two combustion nozzles, which easily lead to uneven heating, local overheating, furnace collapse, and insufficient reaction.

[0015] (2) The control box of this utility model is electrically connected to a torch detector at the input end. There are twelve torch detectors installed inside the furnace body and facing the burner. The torch detectors can monitor the flame status of each burner in real time and determine whether it is ignited normally to ensure combustion safety. Once a flameout or dangerous flame signal is detected, the gas supply of that circuit or related circuit is immediately cut off to improve equipment safety. Attached Figure Description
