Description

Technical Field

[0001] This utility model relates to the field of exhaust gas systems, specifically a novel exhaust gas system for range hoods. Background Technology

[0002] A range hood is an electrical appliance installed above a kitchen stove to purify the kitchen environment. The exhaust fumes from a range hood contain a large amount of particulate matter, volatile organic compounds (VOCs), and odor-causing substances. These components are produced at high temperatures during the heating of cooking oil and food, and include aldehydes, ketones, hydrocarbons, fatty acids, alcohols, aromatic compounds, lipids, and heterocyclic compounds.

[0003] Currently, when treating exhaust fumes from range hoods, the exhaust pipes of multiple range hoods need to be connected to a common main duct. The exhaust fumes from multiple range hoods are then collected and treated through the main duct. However, this method can lead to situations where high-pressure exhaust fumes enter low-pressure exhaust ducts when the exhaust fumes from different range hoods have different pressures, thus affecting the normal treatment of the exhaust fumes. Therefore, a new type of range hood exhaust system is needed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that when multiple range hoods emit exhaust gases with different pressures, high-pressure exhaust gas may enter the pipes of low-pressure exhaust gas. This invention provides an exhaust gas system.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] An exhaust gas system includes: a processing chamber, wherein a plurality of air inlet pipes of varying lengths are fixedly penetrated through the surface of the processing chamber, and a processing unit for treating the exhaust gas inside the processing chamber.

[0007] Furthermore, the processing chamber includes a main chamber body, the top of which is provided with an exhaust port, and several air inlet pipes are fixedly inserted through the surface of the main chamber body.

[0008] Furthermore, the processing unit includes a spray pipe fixedly installed on the inner wall of the main chamber, as well as an ozone generating unit and a drainage unit. The ozone generating unit is used to introduce ozone into the interior of the main chamber, and the drainage unit is used to drain the water inside the main chamber.

[0009] Furthermore, the spray pipe includes a main pipe fixedly installed on the inner wall of the main chamber, a plurality of pressurized spray heads are fixedly penetrated through the inner wall of the main pipe, a water inlet is provided on the surface of the main pipe, and the inner wall of the water inlet is fixedly inserted into the inner wall of the main chamber and has a threaded groove.

[0010] Furthermore, the ozone generating unit includes an ozone generator fixedly installed on the top of the main chamber, the ozone generator being electrically connected to a controller fixedly installed on the surface of the main chamber, an exhaust pipe being fixedly passed through the inner wall of the main chamber, and a plurality of exhaust holes being opened on the surface of the exhaust pipe, the exhaust end of the ozone generator being connected to the exhaust pipe.

[0011] Furthermore, a Pall ring is fixedly installed on the inner wall of the exhaust port.

[0012] Furthermore, the drainage unit includes a bent pipe fixedly penetrating the surface of the main chamber, and the other end of the bent pipe is fixedly connected to a water pump, which is electrically connected to the controller.

[0013] Furthermore, one end of each of the several air intake pipes is fixedly equipped with an air baffle bracket.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, by fixing several air inlet pipes of different lengths through the surface of the processing chamber, the user can introduce the exhaust gas from multiple range hoods into different air inlet pipes during use. Even if the exhaust gas pressure from multiple range hoods is different, the pressure will drop rapidly after the exhaust gas enters the interior of the main chamber due to the sudden increase in space. The air inlet pipes of different lengths make it more difficult for high-pressure exhaust gas to rush into the interior of other air inlet pipes before the pressure drops, thus ensuring the normal input of exhaust gas.

[0016] 2. In this utility model, by fixing a baffle bracket at one end of several air inlet pipes, and the openings of the several baffle brackets are oriented differently, multiple exhaust gases can be discharged in different directions under the guidance of the openings, further preventing high-pressure exhaust gas from entering the air inlet pipe of low-pressure exhaust gas.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] This embodiment provides an exhaust gas system, primarily designed to address the problem of high-pressure exhaust gas entering low-pressure exhaust gas ducts when multiple range hoods emit exhaust gases at varying pressures. The following technical solution is provided in conjunction with... Figures 1-4 Please provide a detailed explanation:

[0024] A waste gas exhaust system includes a processing chamber 1 with several intake pipes 2 of varying lengths fixedly inserted on its surface. In use, the user introduces waste gas from multiple range hoods into the intake pipes 2. The higher-pressure waste gas enters the processing chamber 1 and rapidly depressurizes (the processing chamber 1 has a large internal space). Because the intake pipes 2 are of varying lengths, the higher-pressure waste gas will not enter the lower-pressure intake pipe 2 until it reaches a certain pressure. During the waste gas entry process, the user opens the processing unit 3 for rapid waste gas treatment. The main components of the processing chamber 1 are: a main chamber body 11 with an exhaust port 12 at the top; and if... Each of the two intake pipes 2 is fixedly installed through the surface of the main chamber 11. After the exhaust gas is treated, it will be discharged from the exhaust port 12 located at the top of the main chamber 11. The main components of the treatment unit 3 are: a spray pipe 31 fixedly installed on the inner wall of the main chamber 11. During use, the user needs to introduce ozone into the interior of the main chamber 11 through the ozone generating unit 32 and spray water into the interior of the main chamber 11 through the spray pipe 31. Because water can dissolve ozone to form an ozone solution, this dissolution process allows the ozone to be more evenly distributed in the exhaust gas to be treated, thereby increasing the chance of contact with pollutants. In this process, water acts as a reaction medium between ozone and pollutants. Ozone can decompose in water to produce highly oxidizing free radicals (such as hydroxyl radicals). These free radicals can quickly oxidize and decompose organic pollutants in the water. Finally, the user can discharge the wastewater through the drainage unit 33. It should be noted that each of the two intake pipes 2 is fixedly installed with a baffle bracket 5, and the openings of the baffle brackets 5 face different directions.

[0025] By fixing several air inlet pipes 2 of different lengths through the surface of the processing chamber 1, users can direct the exhaust gas from multiple range hoods into different air inlet pipes 2 during use. Even if the exhaust gas pressure from multiple range hoods is different, the pressure will drop rapidly after the exhaust gas enters the interior of the main chamber 11 due to the sudden increase in space. The air inlet pipes 2 of different lengths make it more difficult for high-pressure exhaust gas to rush into the interior of other air inlet pipes 2 before the pressure drops, thus ensuring the normal input of exhaust gas.

[0026] By fixing a baffle bracket 5 at one end of each of the several air intake pipes 2, and with the openings of the several baffle brackets 5 facing different directions, multiple exhaust gases can be discharged in different directions under the guidance of the openings, further preventing high-pressure exhaust gas from entering the air intake pipe 2 of low-pressure exhaust gas.

[0027] like Figure 1 and Figure 3As shown, in some embodiments, the main component of the spray pipe 31 is a main pipe 311 fixedly installed on the inner wall of the main chamber 11, and several pressurized spray heads 312 are fixedly inserted through the inner wall of the main pipe 311. During use, the user needs to introduce water into the inner wall of the main pipe 311 through a water inlet 313 (the water inlet 313 is fixedly inserted through the inner wall of the main chamber 11 and has a threaded groove 314 for connecting the water pipe) on the inner wall. The main component of the ozone generating unit 32 is an outlet pipe 323 fixedly inserted through the surface of the main chamber 11. In use, the user can generate ozone by controlling the ozone emitter fixedly installed on the surface of the main chamber 11 and introduce it into the interior of the exhaust pipe 323. Finally, it enters the surrounding area of ​​several air inlets 2 through several air outlets 324 opened on the surface of the exhaust pipe 323 and comes into contact with the exhaust gas. The main components of the drainage unit 33 are: a bent pipe 331 fixedly penetrates the surface of the main chamber 11. In use, the user can turn on the water pump 332 fixedly installed at one end of the bent pipe 331 through the controller 322, so that the wastewater inside the main chamber 11 can be discharged through the bent pipe 331.

[0028] like Figure 2 As shown, in some embodiments, a Pall ring 4 is fixedly installed on the inner wall of the exhaust port 12. The Pall ring 4 is existing technology and is commonly used for exhaust gas purification. The annular structure and internal pores of the Pall ring 4 can effectively increase the contact area between the gas and the liquid, thereby enhancing the mass transfer process. This design improves the mass transfer rate, enabling harmful substances in the exhaust gas to be oxidized and decomposed more quickly. This will not be elaborated on further here.

[0029] The working process of this utility model is as follows: First, the user needs to introduce the exhaust gas from multiple range hoods into different air inlet pipes 2. After the multiple exhaust gases enter the main chamber 11, the pressure will drop rapidly. Then, the user inserts the external water pipe threaded into the inner wall of the threaded groove 314, and introduces water into the main chamber 311. Finally, the ozone generator 321 and the water pump 332 are turned on by the controller 322, so that ozone is generated inside the main chamber 11 and reacts with the exhaust gas. Finally, the wastewater is extracted by the water pump 332, and the exhaust gas is discharged from the exhaust port 12.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
