一种粉料罐超压环保防护方法
By setting the opening pressure of the gas supply pressure safety valve in the powder tank system to be lower than that of the powder tank pressure safety valve, and using the gas pressure difference control, the dust pollution and explosion risk caused by overpressure in the powder tank are solved, thus achieving environmental protection.

Abstract
本发明公开了一种粉料罐超压环保防护方法，包括步骤：S1、设置粉料罐压力安全阀的起跳压力小于或等于输气压力安全阀的起跳压力；S2、将出料阀、进料阀和放空阀关闭，将进气阀打开；S3、通过输气管从粉料罐的进气口对粉料罐进行预充压；S4、当粉料罐内预充压到指定压力后，打开出料阀，粉料罐内粉料经出料阀从出料管输送出去，当出料管上出现异常引起粉料罐超压时，输气管上的输气压力安全阀与粉料罐上的粉料罐压力安全阀因气压压差流动，输气压力安全阀将先起跳降压。本发明在输气管和粉料罐之间有了气压差时，安装在输气主管上的输气压力安全阀将比粉料罐压力安全阀先达到起跳压力而起跳避免粉料罐中粉料外泄。
