Sulfur seal buffer

The utility model relates to the technical field of chemical production equipment, in particular to a sulfur seal buffer, which comprises a buffer body, an observation port is arranged on the buffer body, a sealing plate is arranged on the observation port, and the sealing plate is a structural member made of transparent materials. The observation opening is formed in the buffer body, the observation opening is provided with the sealing plate made of the transparent material, a worker can directly observe the flowing condition of liquid sulfur in the inner cavity of the buffer body through the sealing plate, the buffer body is in a closed state all the time in the process, and the risk of sulfur leakage is avoided; and workers are prevented from being in direct contact with the sulfur, so that the operation risk is reduced. 本实用新型涉及化工生产设备技术领域，具体涉及一种硫封缓冲器，包括缓冲器本体，所述缓冲器本体上设有观察口，所述观察口上设有密封板，所述密封板为透明材质结构件。通过在缓冲器本体上设置观察口，观察口设置采用透明材质制成的密封板，使工作人员可直接透过密封板观察缓冲器本体内腔中液硫的流动情况，过程中缓冲器本体始终处于封闭状态，不会发生硫磺泄漏的风险，也避免了工作人员与硫磺直接接触，降
