AI Technical Summary

Technical Problem

Existing technologies require high-temperature heating for thermal deoxygenation and chemical deoxygenation pollute water quality. Furthermore, membrane deoxygenators lack atomized spraying and multi-stage membrane mass transfer structures, resulting in the inert gas supply failing to dynamically match the influent flow rate, leading to low deoxygenation efficiency, waste of inert gas, and high operating costs.

Method used

The inertial membrane deoxygenation device employing flow self-matching includes an atomizing spray mechanism, a multi-layer membrane packing assembly, an inertial air intake mechanism, a water intake mechanism, a drainage mechanism, and a nitrogen water seal device. The inertial air intake and water intake flow are dynamically matched through an electrical connection between a flow meter and a flow controller. Combined with multi-stage mass transfer deoxygenation, an atomized water film with a particle size of five to ten micrometers is formed, and the nitrogen water seal device is used to achieve sealed exhaust.

Benefits of technology

It achieves efficient and deep deoxygenation at room temperature, with stable dissolved oxygen value in the effluent, meeting the feedwater standards for high-pressure boilers, reducing operating costs, avoiding waste of inert gas, ensuring unchanged raw water quality, and improving mass transfer efficiency and exhaust safety.

Abstract

This invention relates to the field of deoxygenation equipment technology, and more particularly to a flow-matching inertial membrane deoxygenation device, comprising a deoxygenation tower body, an atomizing spray mechanism, a multi-layer membrane packing assembly, an inertial energy inlet mechanism, a water inlet mechanism, a drainage mechanism, an exhaust mechanism, and a nitrogen water seal device. The atomizing spray mechanism and the multi-layer membrane packing assembly are both located inside the deoxygenation tower body. The water inlet mechanism is connected to the atomizing spray mechanism. The drainage mechanism is located at the bottom of the deoxygenation tower body. The exhaust mechanism is connected to the top of the deoxygenation tower body and the nitrogen water seal device. The inertial energy inlet mechanism is connected to the bottom of the deoxygenation tower body. The water inlet mechanism includes a deaerator feed water pump, an inlet pipe, a first flow meter, and a flow regulating valve. The inertial energy inlet mechanism includes an inertial energy inlet pipe and a flow controller electrically connected to the flow meter, used to dynamically adjust the inertial energy intake volume according to the proportion of the inlet water flow. The nitrogen water seal device includes a water seal tank and an inlet pipe extending below the liquid surface.
