The invention discloses a recovery method for hydrogen sulfide gas in the conveying process after the hydrogen sulfide leaks. The method comprises the following steps: pipes (6) are guided out from a roasting fan inlet (4); sealing boxes (2) are additionally arranged at valves (3) and easy-leaking places; the pipes (6), guided out from the roasting fan inlet (4), are leaded under the valves (3) and the easy gas leaking places in box bodies of the sealing boxes (2); and hydrogen sulfide detectors (5) are placed in pipe openings of the box bodies of the sealing boxes (2). The method is simple, is low in one-time investment, improves the accuracy and the promptness of the hydrogen sulfide detectors, furthest protects the safety of polling staff, and reduces the environmental pollution after leakage.
Description
technical field [0001] The invention relates to hydrogen sulfide, in particular to a recovery method for accidentally leaking hydrogen sulfide tail gas during pipeline transportation in the coal chemical production process. Background technique [0002] In the process of coal chemical production, hydrogen sulfide cannot be discharged directly because it is highly toxic. The general method is to let it burn to generate sulfur dioxide, and then use the contact process to generate sulfuric acid. During pipeline transportation and before entering the combustion chamber, hydrogen sulfide will pass through the welding joints of the pipeline and valves and other places that are prone to leakage, especially the valves are prone to leakage due to the influence of many factors such as valve quality, construction quality, and aging of flange gaskets, resulting in Great security risk. In the existing practice, hydrogen sulfide detectors are generally installed at places prone to leaks....
