Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to an air purification device. Background Art

[0002] At present, the research on odor control mainly focuses on the odor generated by industrial production processes, and there is relatively little research on odor control in crowded places. Compared with industrial places, crowded places have complex personnel and limited ventilation, which can easily accumulate many pollutants, thus causing odor and NH in the space. 3 , PM 10 and other pollutants exceeded the standard.

[0003] The methods for odor control in industry are divided into three categories: physical, chemical and biological. Physical methods include ventilation, ionization, adsorption, absorption and membrane separation; chemical methods include photocatalytic oxidation, ozone catalytic oxidation and chlorine dioxide disinfection; biological methods include enzyme oxidation, plant purification and biological filters. The above three methods have a good purification effect on odorous gases generated by industry, but they have certain limitations for crowded places (such as hospitals, dormitories, etc.).

[0004] In the existing technology, the odor control in crowded places can generally be carried out by ventilation, spraying odor decomposition liquid, odor collection, air purifiers and other methods: the air purifier treatment is to collect and treat the odor gas through internal circulation wind, but the odor treatment process of most air purifiers is relatively simple, the process only uses primary filtration + adsorption, and the odor removal ability is low. At the same time, the existing air purification equipment has a relatively single function, which limits its application in air purification. Utility Model Content

[0006] The utility model provides an air purification device, including a box body, wherein opposite ends of the box body are respectively provided with air inlet holes and air outlet holes, a mounting plate with ventilation holes is fixed on the inner wall of the box body, the mounting plate divides the interior of the box body into a fan room and a purification room, a fan is arranged inside the fan room, the fan is mounted on the mounting plate and the air outlet of the fan is butted against the ventilation holes of the mounting plate, a filter plate, an adsorption plate and a plant extract storage box are arranged in the purification room, an upper slide groove is fixed on the top plate of the purification room, a lower slide groove is fixed on the upper bottom plate of the purification room just below the upper slide groove, the filter plate and the adsorption plate are both plugged between the upper slide groove and the lower slide groove, there are several plant extract storage boxes and all of them are provided with a cover body, the cover body is provided with an opening mechanism, the bottom ends of all the plant extract storage boxes are fixed on the upper surface of the plug plate, and the plug plate is plugged on the lower slide groove.

[0007] Furthermore, an opening is provided on the side plate of the purification chamber, and an inspection door is provided in the opening, and the inspection door is fixed to the side plate of the purification chamber by screws. The function of the opening is that when the filter plate and the adsorption plate have been used for a long time or are damaged, the filter plate and the adsorption plate can be pulled out between the upper slide groove and the lower slide groove at the opening for replacement. At the same time, when the plant extract in the plant extract storage box evaporates to a certain extent, the plug plate can be pulled out to add the plant extract into the plant extract storage box. After the operation is completed, the inspection door is fixed by screws to close the opening.

[0008] Furthermore, the filter plate includes a first filter plate and a second filter plate stacked together, both of which are nanofiber filter materials, and the filter aperture of the first filter plate is larger than the filter aperture of the second filter plate, and the first filter plate faces the windward side. The function is to remove particulate matter from the gas blown in by the fan and reduce the concentration of particulate matter in the indoor air. The adsorption material is made of nanofiber material, which has high efficiency and obvious effect. At the same time, the first filter plate is used to perform preliminary filtration and removal of large particles in the gas, and then further filtration and removal through the second filter plate to improve the filtration effect.

[0009] Furthermore, the adsorption board is an activated carbon fiber adsorption board, which is used to adsorb and remove odor substances in the gas. Furthermore, the activated carbon fiber adsorption board is pre-impregnated with acid and can be used as NH 3 Special adsorption materials to improve odorous gases, especially NH 3 removal efficiency.

The function is that each extract storage box cover can be individually controlled by the opening mechanism, and the DC reduction motor drives the cover to rise and fall, thereby realizing the opening and closing of the extract storage box opening, thereby improving the degree of automation.

[0011] Furthermore, an electric heating rod is vertically fixed at the center of the bottom plate of the extract storage box, the upper end of the electric heating rod passes through the cover, and a felt layer is wrapped around the outer surface of the electric heating rod. Furthermore, the felt layer is located below the cover when the cover is in a closed state. The functions are: first, the electric heating rod has a heating effect. When the plant extract stored in the extract storage box has poor volatility or the ambient temperature is low, the volatility is increased by heating the plant extract; second, the felt layer is immersed in the plant extract. When the liquid level of the plant extract decreases, the felt layer increases the volatilization area under the infiltration effect; third, the electric heating rod passes through the cover to provide a vertical guide when the cover is raised or lowered.

[0012] The beneficial effects of the utility model are:

[0013] (1) The utility model adopts a fan to collect odorous gases in the environment.
