fiber activated carbon plus automatic activation function deodorization device. In view of the insufficient adsorption and deodorization of granular activated carbon, some display cooler manufacturers have developed this new type of deodorization device. Ion plate deodorizer is one of them. The flow direction of the cold air in the equipment of the deodorizer. In order to completely remove the air in the cabinet, the deodorizing device should be installed at the entrance of the return air duct, which is the only way for the air-conditioning in the display cooler. The cold air from the evaporator passes through the air duct, passes through the refrigerator room, the ice greenhouse, and the vegetable room, and then returns to the evaporator through the deodorizing device. The structure of the odor coating device, the display cooler contains ion plates and honeycomb fiber activated carbon, which can absorb, decompose and neutralize the passing odor to remove the odor. The honeycomb fiber activated carbon in the deodorization device quickly adsorbs a large amount of odors on a few ion plates, and then oxidizes and deodorizes and deodorizes at the same time. It mainly decomposes the odor components adsorbed by the activated carbon in the display cooler into low molecular weight molecules. Released after the smell.

　　 Compared with granular ones, the fibrous activated carbon in the display cooler has a larger external surface area, and the speed of adsorption and deodorization also increases. The activation. The display cooler activation is to remove the tar adhering to the pores of the carbide to form pores. The granular activated carbon has micropores at the luan of the small pores. Unlike granular activated carbon such as coconut shell activated carbon, the micropores of the display cooler fiber activated carbon are the exposed surface of the fiber, which has the characteristic of quickly adsorbing gaseous molecules. Honeycomb fiber activated carbon is made of cut fiber activated carbon and pulp into paper sheets, and then the paper sheets are processed into a shape and stacked into a honeycomb shape. Compared with the granular activated carbon filling layer, the display cooler honeycomb fiber activated carbon is caused The pressure loss is significantly reduced, and the odor molecules that reach the surface can be quickly adsorbed.

　　 display cooler ozone plus catalyst deodorizing device. It is a kind of deodorization device developed to solve the problem of deodorization of general ozone generators. Two layers of honeycomb catalysts are installed in the air supply duct. Electrodes (ceramic electrodes) are installed in the middle, which are produced by surface discharge. ozone. The catalyst in the display cooler can not only improve the deodorizing effect, but also decompose the remaining ozone to prevent the ozone from flowing into the box. The ozone attached to the catalyst decomposes /, so the catalyst is continuously activated. Because it is placed in the multi-vent air duct and does not require a dedicated fan, it is energy-saving and quiet.

　　 heating tube deodorizing device. It is made by coating the heated surface of the defrosting glass tube used in the indirect cooling display cooler with a deodorizing catalyst. The catalyst has two components: one is a catalyst used for adsorption, such as silica, alumina, etc.; the other is a catalyst that decomposes adsorbed odor, such as platinum and cerium oxides.

　　 is installed by the display cooler defrosting heater in the passage of the cold air circulation, so the odor in the display cooler is constantly adsorbed by the adsorption catalyst on the surface of the glass tube during the operation of the display cooler. When the display cooler defrosts, the heating tube is energized. While the evaporator is defrosting, the catalyst coated on the tube is also heated. The decomposing catalyst can oxidize and decompose the adsorbed odor to become odorless after being heated. And desorb on the catalyst coating, and the generated oxides and water are discharged from the drain pipe. This method is used in the display cooler Sunflower to eliminate drought and ping-pong fruit hate elbow, and Liyi uses Chenxiang's deodorizing device.
