Abstract

The invention discloses a device for utilizing waste heat from the production of liquid sulfur trioxide, which comprises a sulfur burner and a pyrolyzer, wherein an air inlet pipe of the sulfur burner is connected with an air blower, the sulfur burner is provided with an air outlet, the pyrolyzer is provided with an air inlet, and a connection pipeline is arranged between the air outlet and the air inlet; the connection pipeline is provided with a connector, and the air blower is further connected with the connector through an air supply pipeline; and the top of the pyrolyzer is provided with an air exhaust port. The invention optimizes the utilization of waste heat from the production of liquid sulfur trioxide. By using the device for utilizing waste heat from the production of liquid sulfur trioxide, the combined production of liquid sulfur trioxide and ethenone can be realized; and the device is simple in structure and low in investment, operation and maintenance cost, has low technical requirements and lowers the ethenone production cost. The invention is applicable to chemical industry production enterprises.

Description

technical field [0001] The invention relates to waste heat utilization for producing liquid sulfur trioxide, and more particularly to a waste heat utilization device for producing liquid sulfur trioxide. Background technique [0002] The sulfur combustion method is currently the production of SO 3 The main method, which mainly includes two-step reactions: [0003] (a) S+O 2 → SO 2 +ΔH [0004] [0005] The above (a) step reaction is carried out in a sulfur incinerator. In the (a) step reaction, the sulfur combustion releases ΔH as high as 9282KJ / Kg, and the combustion reaction produces 900 ° C mainly containing SO 2 The high-temperature furnace gas in the step (b) needs to be cooled to about 430° C. during the step (b) reaction. At present, a medium-pressure boiler is usually installed in the above-mentioned reaction equipment to recover and utilize the heat released during the cooling process of the high-temperature furnace gas, and the medium-pressure boiler produc...
