[0002] In boiler feedwater treatment, membrane contactors need to efficiently remove dissolved gases from the water by drawing a vacuum. In traditional processes, a single water ring pump is often used for vacuum treatment.

[0003] In existing technologies, using a single water ring pump makes it difficult to guarantee the required vacuum level when the water temperature is high in summer. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum treatment device based on membrane contactor deoxygenation process, in order to solve the problem mentioned in the background art that it is difficult to ensure the required vacuum level when the water temperature is high in summer by using a single water ring pump.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a fixed frame, the top of which is equipped with a vacuum processing mechanism, the vacuum processing mechanism comprising a Roots pump, a water ring pump, a gas connecting pipe, and a steam outlet pipe; the top of which is equipped with a gas-liquid separation mechanism, the gas-liquid separation mechanism comprising a steam outlet connecting pipe, a separation container, an inlet baffle, a wave deflector, an exhaust pipe, a drain pipe, an internally threaded fixed pipe, a threaded connecting pipe, a filter pipe, and an activated carbon filter element.

[0006] In a preferred embodiment, the top of the mounting bracket is fixedly connected to the bottom of the Roots pump, the bottom of the mounting bracket is fixedly connected to the bottom of the water ring pump, the outlet of the Roots pump is fixedly connected to the top of the gas connecting pipe, the bottom of the gas connecting pipe is fixedly connected to the inlet of the water ring pump, and the outlet of the water ring pump is fixedly connected to one end of the outlet pipe.

[0008] In a preferred embodiment, the inner bottom wall of the separation container is fixedly connected to the outer wall of the baffle plate, the bottom of the separation container is fixedly connected to the top of the drain pipe, and the drain pipe extends into the interior of the separation container.

[0009] In a preferred embodiment, the top of the separation container is fixedly connected to the bottom of the exhaust pipe, and the bottom of the exhaust pipe extends into the interior of the separation container.

[0010] In a preferred embodiment, the top end of the exhaust pipe is fixedly connected to one end of the internally threaded fixing pipe, and the inner wall of the internally threaded fixing pipe is threadedly connected to the outer wall of the threaded connecting pipe.

[0011] In a preferred embodiment, the threaded connecting pipe is provided in two sets, with one end of the threaded connecting pipe near the internal threaded fixing pipe fixedly connected to one end of the filter pipe, and one end of the other set of threaded connecting pipes fixedly connected to the other end of the filter pipe.

[0012] In a preferred embodiment, the filter tube has a central groove inside, and the inner wall of the central groove is fixedly connected to the outer wall of the activated carbon filter element.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, gas enters the interior of the Roots pump through the top air inlet, and then enters the interior of the water ring pump through the gas connecting pipe. At the same time, water enters the interior of the water ring pump through the water inlet. Vacuum treatment is achieved through the combination of the Roots pump and the water ring pump, which eliminates the need for the traditional single pump body setting. This ensures the vacuum level when the water temperature is high in summer, and reduces energy consumption under the same vacuum level requirements.

[0014] 2. In this utility model, the gas generated by the water ring pump enters the interior of the separation container through the steam outlet pipe and the steam outlet connecting pipe. Then, the gas and liquid are separated by the inlet baffle. The separated water is prevented from flowing by the wave baffle and then discharged through the drain pipe. The gas enters the interior of the filter tube through the exhaust pipe and the internal threaded fixed pipe. It undergoes secondary filtration through the activated carbon filter element inside the filter tube to reduce the water content in the gas. By rotating the filter tube, the threaded connecting pipe is driven to rotate inside the internal threaded fixed pipe, thereby allowing the threaded connecting pipe to be disassembled and replaced. The separation container facilitates the gas-liquid separation of the discharged gas, the detachable filter tube facilitates secondary filtration, and the threaded connecting pipe and the internal threaded fixed pipe facilitate the replacement and disassembly of the filter tube.
