Problems solved by technology
This makes the equipment of the sulfur trioxide preparation system huge, complex in structure, cumbersome in process, low in conversion rate, large in catalyst consumption, short in service life, and high in energy consumption.
[0007] In addition, the liquid sulfur in the liquid sulfur delivery pipe is usually transported by a centrifugal pump, and the flow of the liquid sulfur is regulated by a regulating valve. This delivery method has the disadvantages of low flow control accuracy and high energy consumption, and due to the high viscosity of the liquid sulfur , the control valve is prone to blockage and other faults

The invention relates to the technical field of chemical equipment and discloses a brimstone furnace which is used to burn liquid sulfur and generate sulfur dioxide. The brimstone furnace comprises a brimstone furnace shell, wherein the upper part of the brimstone furnace shell is provided with a liquid sulfur inlet, the lower end of the brimstone furnace shell is provided with an air inlet; and the inside of the brimstone furnace shell is provided with a combustion platform in which liquid sulfur can flow downstream. In the brimstone furnace provided by the invention, the inside of the brimstone furnace shell is provided with the combustion platform for the downstream flowing of liquid sulfur, liquid sulfur enters the brimstone furnace shell from a liquid sulfur delivery pipe and is sprayed to the upper end of the combustion platform; liquid sulfur flows down layer by layer along the side of the combustion platform when burnt layer by layer; and the combustion platform provides enough surface area so that liquid sulfur can fully contact with the air, liquid sulfur can be burnt completely and the amount of the sublimated liquid sulfur is reduced. The invention also discloses a sulfur trioxide preparation system of the brimstone furnace.
Description
technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a sulfur furnace for burning liquid sulfur to generate sulfur dioxide. The present invention also relates to a sulfur trioxide preparation system provided with the above-mentioned sulfur burning furnace. Background technique [0002] Sulfur trioxide is a commonly used chemical product, which is widely used in sulfonation, sulfuric acid, fertilizer, environmental protection and other fields. [0003] Currently, sulfur trioxide is usually produced by burning liquid sulfur in a sulfur trioxide production system. In the prior art, the commonly used sulfur trioxide preparation system usually includes a sulfur furnace, a conversion tower, a liquid sulfur delivery pipe, and an air flow delivery pipe. The air inlet of the furnace is connected, and the air outlet of the sulfur burning furnace is connected with the air inlet of the conversion tower. [0004] Liquid sulfur wit...
