Description

Energy saving and environmental protection gas burner

technical field

The utility model belongs to the heating field and specifically designs a gas stove.

Background technique

At present, the number of gas stoves used in dining places such as hotels and restaurants is very large, and there are many gas stoves in the kitchens of many large hotels and restaurants. These gas cookers are provided with an air inlet pipe and a combustion head. A mixture of natural gas and air is passed into the intake pipe, and the combustion head is made of metal mesh, which is densely covered with micro-holes. The gas in the intake pipe is sprayed directly against the metal mesh, igniting a fire. Due to the high flow velocity of the mixed gas, the impact force of the airflow on the stove is very large, and the noise generated is also very large. Especially when many stoves are arranged in the kitchen, the noise in the kitchen is very large. Exposure to this environment for a long time will bring health threats to the chef. Furthermore, the existing commercial gas stoves generally have insufficient combustion and low thermal efficiency.

Utility model content

In order to solve the above-mentioned problems, the utility model provides an energy-saving and environment-friendly gas burner, which can greatly reduce noise and burn fully.

The solution adopted by the utility model to solve its technical problems is: design an energy-saving and environment-friendly gas burner, including a furnace bowl, a combustion net is arranged in the furnace bowl, and the combustion net is connected with the gas pipe, and the feature is that the furnace bowl below the combustion net The secondary honeycomb board and the first-level splitter are fixed in sequence. The second-level honeycomb board is densely covered with small holes, and the first-level splitter is provided with more than one airflow hole. It is composed of connecting sheets arranged in a circle, and the diaphragms and connecting sheets are fixedly connected together, and micropores are formed between adjacent diaphragms and connecting sheets.

In the utility model, slotted holes are arranged from top to bottom on the connecting piece, and each diaphragm is stuck in the slotted hole. The connecting pieces are obliquely distributed on the circumference of the diaphragm.

The beneficial effect of the utility model is that: when the gas is passed into the burner, the airflow passes through the first-level diversion partition in turn, and after the second-level honeycomb board and the holes on the combustion net are diverted, the flow rate of the gas is greatly reduced; Inclined setting, the gas passing through the combustion net forms a vortex, so the impact force of the airflow is significantly reduced, the noise is reduced, and the combustion is more complete.

Detailed ways

The key to solving the noise of the gas stove is to reduce the flow rate of the airflow. Since the gas flow rate is large, and the large flow rate has the greatest impact on the small hole noise reduction, it is necessary to control the flow first.

As shown in FIG. 1 , the stove head cover 1 and the stove bowl 9 are fixed together, and the bottom of the stove bowl 9 communicates with the gas pipe 8 . In Fig. 3, the furnace bowl 9 is fixedly provided with a first-level splitter 7 and a second-level honeycomb panel 6 in sequence, the second-level honeycomb panel 6 is densely covered with small holes, and the first-level splitter 7 is evenly provided with a plurality of airflow holes. Diaphragm 3 , connecting piece 2 and connecting piece 5 evenly distributed on the circumference form combustion net 10 together. Open long holes (as shown in Figure 5 ) on each connecting piece from top to bottom, and each diaphragm is stuck in the long holes. The diaphragms and connecting sheets are fixedly connected together, and micropores are formed between adjacent diaphragms and connecting sheets. The upper end of each diaphragm is fixed together with the burner cover 1, and the lower end of each diaphragm is fixed together with the burning net seat 4. As shown in FIG. 4 , the connecting piece 2 is arranged obliquely along the circumference of the diaphragm 3 .

Fig. 2 has listed the positional relation of each component of the present utility model, so that understanding.

Natural gas or liquefied petroleum gas is mixed with air and sprayed to the first-stage splitter 7 through the air pipe 8. The air holes evenly opened on the first-stage splitter 7 divert the high-pressure airflow and then enter the second-stage honeycomb panel 6, and the second-stage honeycomb panel 6 The dense micropores further divide the air flow, and the divided gas enters the micropores on the combustion grid 10 again. After three splits, the pressure of the mixture is greatly reduced, so the speed and impact are also greatly reduced. Since the connecting pieces on the combustion grid are arranged obliquely, the gas passing through the combustion grid forms a vortex, so the impact force of the airflow is significantly reduced, the noise is reduced, and the combustion is more complete.

The above scheme uses the principle of micro-perforated plate noise reduction, and uses porous metal materials with sound absorption characteristics to achieve the purpose of reducing noise. Then further use the principle of vortex noise reduction to further minimize the noise on the combustion grid. A vortex is formed to reduce the pressure at the center and reduce the noise. After a flow control, the gas enters the expansion chamber for further decompression and noise reduction. After the gas is depressurized by a large volume, a low-pressure gas is ejected. During this process, the airflow is ejected through a small aperture. The sound power in the octave band is already reduced.
