Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of air deodorization and purification, and particularly relates to a circulating spray deodorization device based on a hydrophobic microporous membrane, which is applied to classrooms, public toilets, high-speed rails, airplanes and various other scenes to improve air quality and create a fresh environment. BACKGROUND

[0002] With the rapid development of social economy and the continuous acceleration of urbanization, the environment of public places such as classrooms, public toilets, high-speed rails and airplanes is prone to produce various odors due to the concentration of personnel, the relative closure of space and the limited ventilation conditions, which seriously affects the comfort and physical and mental health of people. Therefore, how to effectively remove the odor in public places and create a fresh and pleasant environment has become a top priority.

[0003] At present, common deodorization methods mainly include physical adsorption, chemical oxidation and biological filter pool. The physical adsorption method mainly uses adsorbents such as activated carbon to adsorb odor molecules in the air, but due to the limited adsorption capacity, the adsorbent needs to be replaced frequently, which not only increases the maintenance cost but also brings inconvenience. The chemical oxidation method converts odor molecules into harmless substances by reaction with oxidizing agents, but the storage and use of oxidizing agents have safety hazards and may cause secondary pollution to the environment. The biological filter pool method uses microorganisms to degrade odor substances, but this method has the disadvantages of large occupation area, high energy consumption and strict requirements for temperature, humidity and other environmental conditions.

[0004] In order to solve the above problems, a deodorization technology based on hydrophobic microporous membrane has been developed in recent years. This technology uses the interception effect of hydrophobic microporous membrane on atomized water droplets to realize gas-liquid separation and reduce water consumption. At the same time, with the help of the surface tension effect of atomized water droplets, a layer of water film is formed on the surface of the hydrophobic microporous membrane, which improves the absorption and barrier efficiency of malodorous gas. However, the existing hydrophobic microporous membrane deodorization device is often complex in structure, high in cost and lacks flexibility, which is difficult to adapt to the needs of different application scenarios.

[0005] The deodorization needs of classrooms, public toilets, high-speed rails and airplanes are different. Classrooms need to ensure a healthy learning environment for students, public toilets need to be deodorized quickly, and high-speed rails and airplanes need small, light and low-energy deodorization devices.
