Description

   Improved soot dust odor separation device   

The invention relates to a device for separating fumes, dust, and odors, and particularly to a technology and a processing mechanism for using aerodynamic principles to guide and mix liquids, liquid solutions, impacts, and forced liquid-gas mixtures. Improved soot dust odor separation device for filtering impurities such as oil fume, dust, odor and dirt from the gas.

Industrial development has brought many convenient and progressive lives for human beings. However, due to many processes in the manufacturing process of industrial products, dust, smoke, and oil mist can be generated, such as mixing powdery materials, mechanical operations, lathes, grinding machines, milling machines, planers, Gas cutting, laser cutting ... Processing or finishing machines and objects to remove rust ... will produce oil mist and smoke gas, causing the operator and nearby people to inhale dust and oil mist, causing long-term injury to the human body.

Not only that, whether it is a roadside stall or a restaurant, a large amount of oil fume is generated when it is fried, grilled, cooked or fried. Most of the oil fume was directly discharged into the environmental space in the past. There are also some industries that use exhaust fans to discharge oil fume through the pipeline into the ditch. On the surface, the oil fume is not discharged to the atmosphere. In fact, the oil fume still returns to the ambient air in accordance with other unclosed gutter covers, causing pollution. .

In response to the above-mentioned problems, related industries have successively introduced various environmental protection industrial dust, oil fume, oil mist gas, and odor removal filtering equipment to reduce the harm to public health caused by poor air quality. However, many structures are not too expensive, otherwise they are too large, complicated, or ineffective.

In order to solve the above problems, related companies have developed oil fume cleaning equipment, as shown in Figures 1 and 2. Figure 1 is a schematic diagram 1 of a conventional oil fume exhaust gas filtering device. The oil fume exhaust gas filtering device 200 uses an exhaust fan to inject exhaust gas into the stored solution. The processing tank 201 of 202 passes through the non-woven filter screen 203 and the solution inside the processing tank to perform liquid surface attachment filtering operation, and filters impurities such as oil fume and dust. FIG. 2 is a schematic diagram 2 of a conventional soot exhaust gas filtering device. The soot exhaust gas filtering device 300 injects exhaust gas into a processing tank 301 in which a solution 302 is stored through a blower, and discharges the gas and liquid after contacting the liquid.

However, due to the effect of the exhaust gas and the liquid solution on the liquid surface of the above-mentioned fume cleaning equipment, and because the exhaust gas is light, when the fume exhaust gas filtering devices 200 and 300 are injected, part of the exhaust gas will directly overflow through the openings 204 and 304, while others enter The exhaust gas inside the soot exhaust gas filtering devices 200 and 300 is only blown across the liquid surface, causing the exhaust gas to pass through quickly and briefly, which cannot be completely cleaned. Therefore, the conventional soot exhaust gas filtering device still has room for improvement.

The purpose of the present invention is to provide an improved soot dust odor separation device, which uses aerodynamic principles to generate kinetic energy, operates the processing mechanism under the liquid surface, uses a forced impact portion to guide the exhaust gas flow direction, and then uses a first impact mixing portion And a second impingement mixing section thoroughly mixes the exhaust gas containing impurities through the liquid solution, and then uses an impingement separating section to peel off the exhaust gas pollutants into the liquid, effectively filtering the oil fume, dust, odor or dirt in the exhaust gas. , Separation and conversion into purified gas for discharge, and the discharged gas can greatly reduce the content of oil fume and odor, thereby achieving the effect of not polluting the environment and maintaining air quality.

In order to achieve the above-mentioned object, the present invention provides an improved soot dust odor separation device, including: a containing groove, an exhaust gas guide pipe, a forced impact portion, a first impact mixing portion, a second impact mixing portion, and One hit the separation section.

The water inlet part is at a height from the base, and guides a liquid to the receiving groove. The water outlet part is adjacent to the base, and can guide the liquid to leave the accommodation groove. The input port is located on the top cover, and guides a medium body to the accommodating tank, so that the medium body is mixed with the liquid.

The exhaust gas guide pipe is connected to the top cover. After the exhaust gas guide pipe leads an exhaust gas to flow in, the exhaust gas is divided into a plurality of exhaust gas flows by an exhaust gas diverting section. The forced impact portion is located in the liquid and corresponds to the exhaust gas guide pipe. When the forced impact portion carries a plurality of the exhaust gas flows, the exhaust gas flows are mixed with the liquid, and the exhaust gas flows are formed in another direction. flow. The first impact mixing portion is located around the outer edge of the exhaust gas guide pipe, and is disposed perpendicular to the extending direction of the exhaust gas guide pipe. The second impact mixing portion is adjacent to the first impact mixing portion, and is disposed perpendicular to the extending direction of the exhaust gas guide pipe. The impact separation part is located around the outer edge of the exhaust gas guide pipe and is adjacent to the second impact mixing part.

Wherein, when the exhaust gas flow flowing in the other direction passes through the first impact mixing portion and the second impact mixing portion in sequence, the gas in the exhaust gas flow and the liquid are remixed and divided into a plurality of bubble flows, The impact separation part peels off the waste gas and dirt in the bubble flow into the liquid to form a net air flow for gas-water separation.

With the above structure, after the exhaust gas to be treated is injected into the accommodation tank through the exhaust gas guide pipe, the exhaust gas will sequentially pass through the forced impact part, the first impact mixing part, the second impact mixing part, and the impact separation part, The fume, dust, odor or dirt in the exhaust gas is filtered and separated, and converted into purified gas for discharge. The discharged gas can greatly reduce the content of fumes and odor, thereby achieving the effect of not polluting the environment and maintaining air quality.
