Abstract
The invention discloses a device for separating and recovering chlorine gas from chlorine gas and hydrogen chloride mixed gas. The device is characterized by comprising a mixed gas buffer which is used for receiving the chlorine gas and hydrogen chloride mixed gas, wherein the mixed gas buffer is connected with an input terminal of a compressor, and an output terminal of the compressor is connected with a condenser; a gas output terminal of the condenser is connected with a hydrogen chloride buffer, and the hydrogen chloride buffer is used for receiving uncondensed hydrogen chloride in the condenser; a liquid output terminal of the condenser is connected with a liquid chlorine recovery tank, and the liquid chlorine recovery tank is used for receiving condensed liquid chlorine in the condenser. According to the device for separating and recovering the chlorine gas from the chlorine gas and hydrogen chloride mixed gas, disclosed by the invention, the hydrogen chloride can be effectively separated, and the liquid chlorine can be effectively recovered, so that the cost is reduced greatly.
Description
Technical field
The present invention relates to the device of Separation and Recovery chlorine from chlorine and chlorine hydride mixed gas body.
