用于气体在线分析的预处理系统
摘要：
用于气体在线分析的预处理系统，包括：降温装置；稳压装置(14)；以及过滤装置，其中，所述稳压装置包括：减压阀(141)，该减压阀(141)与所述降温装置连接，用于对所述低温气体进行减压处理；和增压泵(142)，该增压泵(142)设置有压力传感器(143)，该压力传感器(143)设置在所述增压泵(142)和所述减压阀(141)之间的管路上，用于检测气体的压力，当该压力传感器(143)检测到的气体的压力值不低于第一预定值时，所述增压泵(142)不动作，而当所述压力传感器(143)检测到的气体的压力值低于第一预定值时，所述增压泵运行，以对流经该增压泵的气体进行增压处理。该预处理系统能够确保进入分析仪的气体具有相对稳定的压力。
摘要（英）：

The invention discloses a pretreatment system used for gas on-line analysis, and the system comprises a cooling device, a pressure stabilizing device (14) and a filtering device, wherein the pressure stabilizing device comprises a pressure relief valve (141) and a booster pump (142), the pressure relief valve (141) is connected with the cooling device and used for performing pressure reduction treatment on low-temperature gas, the booster pump (142) is provided with a pressure sensor (143), and the pressure sensor (143) is arranged on a pipeline between the booster pump (142) and the pressure relief valve (141) and used for measuring the pressure of the gas. When the pressure sensor (143) detects that the pressure of the gas is not less than a first preset value, the booster pump (142) does not work; and when the pressure sensor (143) detects that the pressure of the gas is lower than the first preset value, the booster pump works to perform pressurization treatment on the gas which flows through the booster pump. The pretreatment system can ensure that the gas entering an analyzer has a relatively-stable pressure.
