Description

A high-efficiency sulfur trioxide gas dehumidification heating device

technical field

The utility model relates to a high-efficiency sulfur trioxide gas dehumidification heating device.

Background technique

At present, in the processing and production of hydrosulfite (sodium dithionite), it is necessary to use sulfur trioxide for oxidation and vulcanization treatment synthesis. During processing, it is necessary to heat sulfur trioxide and remove water vapor in the gas source.

The existing technology generally uses a heat exchanger to directly heat the sulfur trioxide, which can also heat the sulfur trioxide while evaporating the water vapor in the gas, but the heat exchange efficiency is low, and it cannot be heated quickly. The traditional technology Generally, multiple heat exchanges are used, and the temperature is increased by increasing the number of heat exchanges. This method can only reduce the moisture in the sulfur trioxide to a certain extent, and the heating effect is not good, but the energy consumption is very large, and the heating rate is relatively high. Slow, very low work efficiency, also indirectly affects the production efficiency of hydrosulfite (sodium dithionite), and further, multiple heat exchanges will also affect the purity of sulfur trioxide.
