Description

A black hole gas burner

Technical field:

The utility model relates to a gas combustion furnace used in industry, canteens, power plants and other industries, in particular to a gas combustion furnace with energy saving, high efficiency and environmental protection. the

technical background

The combustion method of the gas in the existing gas burners used in industries, canteens and power plants is open combustion in which the gas is directly sent to the combustion port for combustion, or some mesh or porous gas distribution structures are set at the combustion port to disperse the gas. Some are used in combination with fans, such as the utility model patent "Vertical Injection Swirling High Temperature Resistant Combustion Furnace" with the national published patent number 200620175542.3 and the invention application "safety furnace" with the national published patent application number: 200910128321.9 Energy-saving gas stove". The common disadvantages of these gas burners are: for example, when the gas is supplied at low pressure, the combustion quality is unstable when the high consumption mode is selected, the heat radiation emitted from the flame endangers the operator, and more than 30% of the gas is discharged before the combustion process is complete. To the living space, it still contains harmful substances and gases such as hydrocarbons, methane, and carbon dioxide, causing environmental pollution and wasting precious resources. the

Practical new content

The purpose of this utility model is to solve the problem that the combustion furnace in the prior art cannot completely burn gas when it is used. In this way, not only a large amount of gas is wasted, but also a large amount of harmful gas is discharged, causing serious environmental pollution, thereby affecting the living environment of human beings. Various defects of the invention provide a black hole type gas burner. the

The black hole gas burner includes a safety valve, a furnace body, and a siphon preheating gas drum. An expander is installed in the hearth of the furnace body. The siphon preheating drum surrounds the furnace body in a ring shape and communicates with the passage in the expander. A blocking plate with a round hole in the center is installed on the furnace body. the

The above-mentioned expanders are divided into internal expanders and external expanders. The internal/external expanders are cylinders, cubes, polygons or stars with cavities. There are several through holes distributed on the sides of the cavities. The outer expander covers the inner expander to form a compressed lumen in the middle. the

There are one or more than two internal expanders or external expanders mentioned above. the

A connecting piece is arranged between the above-mentioned internal expander and the external expander. the

An air intake channel is arranged between the furnace body and the furnace hearth, and a plurality of through holes are distributed on the side wall of the furnace hearth. the

The above-mentioned furnace is provided with an electronic igniter. the

The beneficial effects of the utility model are:

1. Since the utility model adopts the gas siphon preheating gas drum, the gas burner can preheat the gas of the burner in the environment of low-pressure gas supply, and overcome the problem of gas supply when the gas is in a large gas volume requirement. Failure to keep up will lead to a decrease in firepower, resulting in a decrease in gas utilization rate and other disadvantages, to achieve the beneficial effects of increased gas utilization rate, stronger firepower, energy saving, and a significant reduction in harmful gas emissions. the

2. Because the utility model adopts an expander, when the gas passes through the expander, the volume of the gas is constantly colliding with each other and expands rapidly, so that the gas can be fully burned and the utilization rate of the gas is greatly improved. the

3. Since the utility model has installed a blocking plate with a round hole on the furnace body, the gas is continuously collided with each other and rapidly expanded through the inner/outer expander in the furnace body, and then further compressed immediately. During the entire combustion process, it is transformed into extremely high heat release to achieve the state of perfect combustion, so that the gas can be burned more fully. the

Detailed ways

Example 1

As shown in Figure 1, the black hole type gas burner of the present utility model includes a safety valve 1, a furnace body 2, and a siphon preheating air drum 3. An expander 4 is arranged in the furnace 21 of the furnace body 2, and the expander 4 is divided into an internal expander 41 and an external expander 42, and the internal/external expander is a cylinder with a cavity 6, and the side of the cavity A number of through holes 61 are distributed, and the outer expander 42 covers the inner expander 41 to form a compressed inner cavity 7 in the middle. A connecting piece 8 is arranged between the inner expander 41 and the outer expander 42, and the connecting block connects the inner The expander 41 is integrated with the external expander, which is convenient for installation and use. The siphon preheating drum 3 is ring-shaped around the furnace body 2 and communicates with the pipeline in the expander 4 in the furnace 21. The pipeline is connected to the gas input port where the safety valve 1 is installed. The blocking plate 5 of the hole 51, the size of the circular hole 51 is 1/10-1/2 of the mouth of the furnace. An air intake passage 9 is arranged between the furnace body 2 and the furnace hearth 21, and a plurality of through holes 211 are distributed on the side wall of the furnace hearth 21, and an electronic igniter 10 is arranged on the furnace hearth 21, and the igniter is fixedly mounted on the furnace body 2 and the hearth 21. the

Example 2

As shown in Figure 2, there are two internal expanders 41 of the black hole type gas burner expander 4 of the present invention, and the others are the same as in Embodiment 1. the

The specific implementation manner will be further described in detail below according to the working principle. the

When the gas enters the burner and starts the electronic igniter 10, the combustion of the gas will preheat the siphon preheating gas drum 3, and the absorbed heat will be conducted to the gas inside the gas drum to expand and boost the pressure of the gas. The gas flows out from the siphon preheating gas drum, and enters the expander 4 through the pipeline. The volume of the gas continuously collides with each other in the inner expander 41 and the outer expander 42 of the expander 4, and expands rapidly until it reaches the furnace 21. The body 2 is equipped with a blocking plate 5 with only a circular hole 51 in the center, so that the gas cannot flow out of the furnace body quickly and is blocked in the furnace 21, so that the gas is continuously compressed in the furnace 21. the

Specifically, when the gas enters the expander 4 in the burner, since the expander 4 is a cylinder with a cavity 6, only a few through holes 61 are distributed on the sides of the cavity as vent holes. When the expander 4 in the burner is blocked by the expander 4 in the inner cavity of the expander 4, it cannot quickly lead to the furnace of the burner. The molecules of the gas can only be squeezed and collided with each other in the expander 4. As a result, the gas molecules move continuously at high speed and generate energy when ignited, and focus on the center of the top of the external expander to form a vortex-shaped black spot, which is ejected from the round hole 51 of the blocking plate 5, so that the gas can be fully burned, and the obtained : The internal expander is divided into multiple layers, and the more intense the mutual extrusion and collision, the better the effect. The temperature can reach above 1100°C. But the furnace combustion chamber is only 200 ℃. Even if the ignition spark has been activated, the flammable gas cannot be ignited in the furnace. the
