[0002] An efficient and energy-saving oil-free screw vacuum pump for desulfurization has important application value in the field of environmental protection. With the increasingly stringent environmental protection policies in my country, desulfurization technology has occupied an important position in industrial production. The main goal of desulfurization technology is to remove sulfur oxides from flue gas to reduce pollution to the atmosphere. In the desulfurization process, the vacuum pump is one of the key equipment. It provides negative pressure conditions for the absorption tower to ensure the desulfurization effect. However, during the desulfurization process, the vacuum pump may inhale some solid particles, smoke and other impurities. Over time, these impurities will accumulate in the pump, affecting the normal operation of the pump. Regular cleaning is required to ensure normal operation, which is time-consuming and labor-intensive. Utility Model Content
