[0002] The buffer tank is an important auxiliary equipment of the reciprocating pump. It is used to reduce the unevenness of the flow in the pipeline. It is divided into two types: suction buffer tank and discharge buffer tank. The function of the suction buffer tank is to reduce the unevenness of the flow in the suction pipeline, reduce inertia loss, and improve the suction performance of the pump. The function of the discharge buffer tank is to reduce the unevenness of the flow in the discharge pipeline and avoid the generation of excessive flow to meet the needs of the process. The structural types of the buffer tank are direct contact type and diaphragm type.

In the utility model, the exhaust gas enters the hollow cavity through the tank body and is then discharged outward through the air outlet pipe. During this process, the exhaust gas squeezes the buffer plate and the movable plate. The second spring is provided to give a buffering force in the vertical direction to the buffer plate. The movable rod is provided with an inclined shape on one side close to the center of the hollow cavity. The movable rod can move in the vertical direction under the impact of the exhaust gas. The first spring is provided to give a buffering force in the vertical direction to the movable rod, so that the tank body has the function of instantaneous deflation, reduces the impact on the exhaust gas treatment equipment, and plays a role in protecting the exhaust gas treatment equipment.

When the buffer tank is in use, the internal pressure may rise sharply and exceed the explosion pressure value of the tank body, causing the tank body to explode and causing fragments to fly and injure people. At the same time, the exhaust gas contains some water vapor and particulate impurities, which will cause damage and pollution to the interior of the tank body 1. Moreover, when the internal buffer air pressure is too high, the internal air pressure of the tank body will increase and cannot be effectively adjusted. Utility Model Content
