Abstract

The utility model relates to an energy saving and environment protecting stove head, belonging to the heating field and including a stove bowl which is internally provided with a burning net which is communicated with a gas pipe. The utility model is characterized in that: the inside of the stove bowl under the burning net is orderly and fixedly provided with a two-stage honeycomb plate and a one-stage distributing and separating plate. The upper part of the two-stage honeycomb plate is closely provided with a plurality of small holes, and the one-stage distributing and separating plate is provided with more than one air flow hole. The burning net consists of a plurality of film sheets which are arranged in an up-down manner and a plurality of connecting sheets arranged surrounding the film sheets, with the film sheets and the connecting sheets fixedly connected with each other and small holes arranged between each two adjacent film sheets and connecting sheets. The utility model has the following advantages: after being conveyed into the stove head, the air flow orderly passes the one-stage distributing and separating plate, the two-stage honeycomb plate and the holes on the burning net for distribution, and then the flowing speed of the air is greatly reduced. As the connecting sheets on the burning net are inclined and the air passing through the burning net forms a whirl, the attack of the air flow is greatly reduced, the noise is lowered, and the burning is more sufficient.

Description

The energy-conserving and environment-protective gas burner

Technical field

The utility model belongs to the heating field, a kind of gas stove of specific design.

Background technology

At present, food and drink places such as hotel use the quantity of gas-cooker very big, are furnished with a lot of gas-cookers in the kitchen in a lot of large-scale restaurants, dining room.These gas-cookers are provided with air inlet pipe and combustion head.Feed natural gas and Air mixing gas in the air inlet pipe, combustion head is made of wire netting, and micro-hole above gathers.Gas in the air inlet pipe directly sprays to wire netting, lights and catches fire.Because the flow velocity of mist is big, thereby air-flow is very big to the impulsive force of kitchen range, the noise of generation is also very big.Particularly when in the kitchen many cooking stoves being set, noise is very big in the kitchen.Place oneself in the midst of for a long time under this environment, bring healthy threat to the cook.Moreover, existing commercial gas stove, generally burning is abundant inadequately, and the thermal efficiency is low.

The utility model content

For addressing the above problem, the utility model provides a kind of energy-conserving and environment-protective gas burner, can reduce noise and sufficient combustion greatly.

The scheme that its technical problem that solves the utility model adopts is: design a kind of energy-conserving and environment-protective gas burner, comprise the stove bowl, in the stove bowl burning web is set, burning web is connected with tracheae, it is characterized in that fixedly installing secondary cellular board and one-level split-flow baffles successively in the stove bowl of burning web below, gather on the secondary cellular board and offer aperture, offer more than one airflow hole on the one-level split-flow baffles, burning web is by being the diaphragm of arranging up and down, arranging the plate that is provided with along the diaphragm border forms, diaphragm and plate are fixedly connected, and form micropore between adjacent diaphragm and the plate.

The utility model is arranged from top to bottom in plate and is offered slotted hole, and each diaphragm is stuck in the described slotted hole.The plate tilt distribution is on the diaphragm border.

The beneficial effects of the utility model are: when feeding gas in the burner, air-flow is successively by the one-level split-flow baffles, and after each the hole shunting on secondary cellular board, the burning web, the flow velocity of gas reduces greatly; Because the plate on the burning web is obliquely installed, the gas by burning web forms eddy current, thereby the impulsive force of air-flow obviously reduces, and reduced noise, and burning is more abundant.

The specific embodiment

The key that solves the gas-cooker noise is to reduce the flow velocity of air-flow.Because gas flow rate is big, noise elimination has the greatest impact and flow velocity is greatly to aperture, so need control stream earlier.

As shown in Figure 1, stove top 1 and stove bowl 9 are fixed together, the bottom connectivity trachea 8 of stove bowl 9.Among Fig. 3, fixedly install one-level split-flow baffles 7 and secondary cellular board 6 in the stove bowl 9 successively, gather on the secondary cellular board 6 and offer aperture, evenly offer a plurality of airflow holes on the one-level split-flow baffles 7.Diaphragm 3, be evenly distributed on the common burning web 10 of forming such as plate 2 on the circumference, plate 5.Offer slotted hole (as shown in Figure 5) in each plate from top to bottom, each diaphragm is stuck in the described slotted hole.Diaphragm and plate are fixedly connected, and form micropore between adjacent diaphragm and the plate.The upper end of each diaphragm and stove top 1 are fixed together, and the lower end of each diaphragm and burning reticulum 4 are fixed together.As shown in Figure 4, plate 2 is obliquely installed along the circumference of diaphragm 3.

Fig. 2 has listed each position component relation of the utility model, so that understand.

Natural gas or liquefied gas mix the back and spray to one-level split-flow baffles 7 by tracheae 8 with air, the pore of evenly offering on the one-level split-flow baffles 7 enters secondary cellular board 6 after high pressure draught is shunted again, the micropore that gathers on the secondary cellular board 6 is further to airflow diversion, and the gas after the shunting enters in the micropore on the burning web 10 again.After three shuntings, the pressure of gaseous mixture reduces greatly, thereby speed and impulsive force also reduce greatly.Because the plate on the burning web is obliquely installed, the gas by burning web forms eddy current, thereby the impulsive force of air-flow obviously reduces, and reduced noise, and burning is more abundant.

Such scheme utilizes the microperforated panel noise-cancelling theory, and the utilization porous metal material has the characteristic of sound absorption, reaches the purpose that reduces noise.Further utilize the eddy current noise-cancelling theory then, on burning web, further noise is reduced to minimum.Form eddy current, the pressure that reduces the centre reduces noise.Enter the further step-down of expansion chambers again through the gas behind the secondary control stream and eliminate the noise, gas sprays thereby form low-pressure gas after big volume step-down, and in this process, air-flow is through the small-bore ejection, and the acoustical power of its each octave band of ejection back just reduces.
