Description

Technical Field

[0001] The utility model relates to the technical field of oil fume waste gas purification, in particular to an oil fume waste gas spraying and odor removal device. Background Art

[0002] The catering industry generates a large amount of oil fume waste gas during the cooking process. These waste gases not only contain grease particles, but also are mixed with various organic substances and thermal oxidation products. Their composition is complex and has a strong odor. Since these oil fume waste gases may pose a threat to the environment and human health, it is particularly important to develop efficient oil fume and odor removal technologies. The spray deodorization device sprays liquid into the oil fume waste gas, and uses the wetting and absorption effect of the liquid to remove grease and odor molecules. Surfactants, alkaline substances or adsorbents are often added to the liquid to enhance the removal effect. The existing oil fume waste gas spray deodorization device sprays an active agent to the exhaust port, and uses the mist active agent to wet and absorb the grease and odor molecules to purify the oil fume waste gas. However, the residual grease and odor molecules in the waste gas are not removed cleanly and are directly discharged into the external environment, which will pollute the atmosphere and affect the urban air quality. Utility Model Content

[0003] In order to overcome the odor in the oil fume exhaust gas spraying and deodorizing device, the existing oil fume exhaust gas spraying and deodorizing device sprays an active agent to the exhaust port, and uses the mist active agent to wet and absorb the grease and odor molecules to purify the oil fume exhaust gas. However, the residual grease and odor molecules in the exhaust gas are not removed cleanly and are directly discharged into the external environment, which will pollute the atmosphere and affect the urban air quality.

When in use, the liquid extraction pump is started to extract the active agent from the active agent storage box to the liquid injection pipe to reach the liquid diverter plate, and then it is sprayed out in a mist form from multiple groups of nozzles, so as to capture most of the oil and odor molecules in the oil fume exhaust gas and temporarily gather and store them at the bottom of the spray box, so as to achieve preliminary filtration of the oil fume exhaust gas.

[0007] Preferably, the exhaust assembly includes an exhaust duct and a first fan; an exhaust duct is provided on one side of the spray box, and a first fan is provided inside the exhaust duct.

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the traditional oil fume exhaust gas spray deodorization device, when removing odor, residual grease and odor molecules will be discharged into the environment to cause pollution. By adopting the method of fine bubbles precipitating from the neutralizer in the oil fume exhaust gas spray deodorization device, the sprayed oil fume exhaust gas is converted into fine bubbles that precipitate from the bottom of the neutralizer. The fine bubbles increase the contact area with the neutralizer, effectively removing grease and odor molecules;

The fine bubbles of oil fume exhaust gas penetrate the activated carbon block from bottom to top. The activated carbon block can adsorb and fix the residual odor molecules in the fine bubbles of oil fume exhaust gas.

[0015] 3. Start the second fan to draw the oil fume exhaust gas that has undergone preliminary spraying treatment to the exhaust duct, and then draw it from the exhaust duct to the neutralizer storage box for secondary treatment to completely remove odor and grease particles.
