Example Embodiment

[0031] Example 1: Portable oil fume treatment device such as figure 1 As shown, the cooking pot 1 is placed on the cooking stove 2. There is cooking oil in the pot 3. The gas enters the burner 4 through the pipe 5 and the valve 6, and after burning and heating the cooking pot, the cooking oil is heated to produce oil fume. Most of the oil fume will be collected by the fume collecting hood 7 of the portable oil fume treatment device. Air, oil fume, peculiar smell gas and some harmful gaseous substances from the combustion of coal gas enter the telescopic tube 8 under the action of the exhaust fan 9 driven by the exhaust fan 10 to form a special gaseous mixture (the telescopic tube is used to adjust the smoke collecting hood And the distance between cooking appliances). The mixture continues to enter the reaction chamber 14 through the ventilation pipe 13 under the action of the exhaust fan. After treatment, it is discharged from the outlet 17 of the reaction chamber, and is direct...

Example Embodiment

[0033] The second embodiment: is another portable oil fume treatment device such as image 3 As shown, this processing device differs from the previous processing device only in that the ventilation pipe 13 is connected to two reaction chambers placed on different stoves. Its purpose is to make full use of the heat energy of different stove burners to separate part of the oil fume and other harmful substances generated on the cooking stove eye to the stove eye that is burning but does not produce oil smoke and harmful substances for treatment. In this way, the power of the exhaust fan can be increased, so that the oil fume and other harmful substances can be sucked to the maximum extent, and the treatment efficiency is improved.

Example Embodiment

[0034] Embodiment 3: It is a fixed oil fume treatment device, such as Figure 4 As shown, the so-called fixed type means that the smoke collecting hood 7, the exhaust fan 9 and the ventilation pipe 13 are connected together and fixed on the wall like a traditional range hood. The vent pipe elbow and the vent straight pipe constitute a long vent pipe and are connected to the reaction chamber 14. The reaction chamber is the same as the reaction chamber in the previous two embodiments, and is also placed on a stove eye of the stovetop 2. The heat energy generated by the burning gas in the stove eye burner provides the required high temperature and metal ventilation in the reaction chamber. The energy required for preheating the mixture in the tube. The oily fume, peculiar smell gas and other harmful substances collected by the fume collecting hood 7 enter the reaction chamber through the ventilation pipe and are oxidized or decomposed by the inhaled oxygen under the action of the hig...

Abstract

The present invention relates to an equipment fo r treating cooking fume, abrnormal smell and other farmful substances and its method. One end of ventilation pipe is communicated with extractor fan near to the cooking stove, its another end is connected with at least one ring reaction chamber with hollow cavity, and the exterior of cooking stove burner is covered with said reaction chamber with at least one outlet. In the interior of the reaction chamber the adsorbing agent, catalyst and filtering screen can be placed. The extractor fan can be used for collecting fume, air, abnormal smell gas and other harmful substances mixture, and the collected mixture is passed through the ventilation pipe, preheated and fed into the reaction chamber, the harmful substance can be oxidated into carbon dioxide and water, or firstly decomposed, then oxidated, and can be discharged into exterior or collected for make secondary treatment.

Description

technical field [0001] The invention relates to a device and method for removing kitchen oil fume, peculiar gas and other harmful substances. Background technique [0002] Most human activities are carried out indoors. Pollution in the indoor environment can lead to various diseases. Cooking fumes and irritating odor gases are one of the main sources of indoor environmental pollution. When the cooking temperature is higher than 130°C, oil fume will start to be produced from the edible oil, which will cause damage to people's respiratory and circulatory systems. Especially when the temperature reaches 230-280°C, some carcinogens may be produced in the oil fume. According to the analysis of Taiwan's Department of Health, the proportion of Taiwanese housewives suffering from lung cancer remains high. The main reason is that they have been in an environment polluted by cooking fumes for a long time. On the other hand, the irritating gas produced during cooking, such as the p...
