Detailed Description
Referring to fig. 1, an embodiment of a device for collecting and treating tail gas from a carbon disulfide storage tank is shown. The carbon disulfide storage tank tail gas collection processing apparatus includes five carbon disulfide storage tanks 1, and the top of five carbon disulfide storage tanks 1 is provided with breather valve 2, relief valve 11 respectively, and the bottom is provided with urgent exhaust valve 8 respectively. The device further comprises an exhaust manifold 3 and a plurality of shut-off valves 4, wherein the upstream end of the exhaust manifold 3 is closed, the downstream end of the exhaust manifold is connected with an air inlet of an air compressor 5 of the claus sulfur recovery device, and a carbon disulfide detector 6 for sending signals to a central control room is arranged on the exhaust manifold 3, and in the embodiment, a check valve 9 is arranged at the upstream end of the exhaust manifold and is connected with a nitrogen source. Each breather valve 2 is connected in parallel to the exhaust manifold 3 through a connecting pipe 7, and the connecting point of the connecting pipe and the exhaust manifold is positioned upstream of the carbon disulfide detector 6. The number of shut-off valves 4 corresponds to the number of breathing valves 2, i.e. five.

The working principle of the utility model is as follows: the liquid-phase carbon disulfide is added into five carbon disulfide storage tanks to be temporarily stored as a raw material for synthesizing dimethyl sulfoxide. In the initial stage, the concentration of carbon disulfide in the exhaust manifold is 0, liquid-phase carbon disulfide in the carbon disulfide storage tank is continuously evaporated to form a gas phase, and the gas phase enters the exhaust manifold through a breather valve and a cut-off valve, and finally is extracted through an air compressor of a Claus sulfur recovery device to be subjected to centralized treatment, so that the concentration of the carbon disulfide in the exhaust manifold is kept at a safety level. If the air compressor of the Claus sulfur recovery device fails, or other reasons cause the concentration of the carbon disulfide in the exhaust manifold to rise, after exceeding the standard is detected by the carbon disulfide detector, a signal is sent to a central control room, and the central control room controls a shut-off valve to be closed, so that the explosion risk caused by the further rising of the concentration of the carbon disulfide in the exhaust manifold is avoided. After the obstacle is removed, the concentration of the carbon disulfide in the exhaust manifold is reduced to a safety level, the linkage cut-off valve is opened, and the gas-phase carbon disulfide is discharged into the exhaust manifold. If the fault can not be eliminated for a long time, a nitrogen source is started, nitrogen is fed into an exhaust manifold, the concentration of the carbon disulfide is diluted, and then a linkage cut-off valve is started, so that the excessive pressure in the carbon disulfide storage tank is avoided.
