What is the function of a process gas ejector? Answer: The main functions of the process gas ejector in the installation are as follows: ① During the startup and heating process of the exhaust gas purification system, the ejector is used to establish a circulation cycle, which allows the low-temperature circulating gas to cool the high-temperature combustion gases from the exhaust gas purification furnace; this ensures the safety of the equipment while also enabling the reactor to be heated up. ②The catalyst presulfurization operation in the exhaust gas purification reactor establishes a process cycle through a pump. ③When a slight blockage occurs in the quench tower due to production abnormalities, the pressure in the exhaust gas purification system rises, resulting in an increase in the load on the plant. In such cases, the ejector can be activated to reduce the pressure in the purification system, thereby creating conditions for increasing the plant’s load. ④During normal production, the process gas ejector will be shut down. ⑤The exhaust gas purification system is shut down; the catalyst is passivated, and gas circulation is established during regeneration. ⑥When the device’s processing capacity is low, a pump is activated to establish a process gas circulation.
