[0022] like Figure 1 — Figure 5As shown, a natural gas combustion device with an enhanced diffusion mechanism comprises: a gas station 1, a first gas pipe 4 is connected to the top of the gas station 1, a gas buffer tank 6 is arranged on the left side of the gas station 1, the end of the first gas pipe 4 is connected to the middle and lower part of the right side of the gas buffer tank 6, and the middle and upper part of the left side of the gas buffer tank 6 is connected to the second gas pipe 7; an enhanced diffusion mechanism, the enhanced diffusion mechanism is provided with a diffusion ring, four nozzles 19 are installed on the diffusion ring 24, the four nozzles 19 are connected to the diffusion ring 24 by welding, and a diffusion hole 25 for spraying flames is opened between two adjacent nozzles 19, the four nozzles 19 are respectively installed on the first branch pipe 9, the second branch pipe 10, the third branch pipe 11 and the fourth branch pipe 12, and the right end of the enhanced diffusion mechanism is connected to the left side of the second gas pipe 7. The first branch pipe 9, the second branch pipe 10, the third branch pipe 11 and the fourth branch pipe 12 are connected to each other.

[0023] In this embodiment, the first gas pipe 4 is connected to a first pressure relief pipe 15, and the first pressure relief pipe 15 is provided with a first pressure relief valve 16. The second gas pipe 7 is connected to a second pressure relief pipe 13, and the second pressure relief pipe 13 is provided with a second pressure relief valve 14. The first pressure relief pipe 4 and the second pressure relief pipe 13 are both connected to a pressure relief main pipe 17, and the pressure relief main pipe 17 is connected to a pressure relief tank 18.

[0024] In this embodiment, a first automatic valve 5 is installed on the first gas pipe 4, a second automatic valve 8 is installed on the second gas pipe 7, and a flow meter 26 is also installed on the first gas pipe 4. The flow meter 26 is used to display the amount of gas used. A third gas pipe 2 is connected to the bottom right side of the gas station 1, and a third automatic valve 3 is installed on the third gas pipe 2. The right side of the third gas pipe 2 is connected to the natural gas main.

[0025] In this embodiment, the bottoms of the four nozzles 19 are all provided with threads 23, and the four nozzles 19 are respectively connected to the first branch pipe 9, the second branch pipe 10, the third branch pipe 11 and the fourth branch pipe 12 through the threads 23, and the four nozzles 19 are symmetrically arranged. Figure 1 As shown, the first branch pipe 9, the second branch pipe 10, the third branch pipe 11 and the fourth branch pipe 12 are connected to each other at the first position, approximately forming a rectangle.

[0026] In this embodiment, a hollow channel 22 is provided inside the nozzle 19, a first injection hole 21 is provided at the top of the nozzle 19, and four second injection holes 20 are provided below the first injection hole 21. The flames sprayed from the four second injection holes 20 are concentrated in the diffusion ring 24, and then sprayed out from the diffusion holes 25 on the diffusion ring 24. This design is combined with the flames sprayed from the first injection hole 21, and the entire diffusion ring 24 can form 8 diffused flames, which can effectively improve the diffusion efficiency and meet the existing carbon black production needs.

[0027] In this embodiment, the four second injection holes 20 are symmetrically arranged, and the four second injection holes 20 are all located in the diffusion ring.

[0028] In this embodiment, the first injection hole 21 has a petal-shaped appearance.

[0029] In this embodiment, the number of the diffusion holes is 4 and they are symmetrically arranged.

[0030] When the device is used, the first automatic control valve 8, the second automatic control valve 5 and the third automatic control valve 3 are opened in sequence, and the natural gas enters the gas station 1 from the natural gas main through the third gas channel 2, and then passes through the first gas pipe 5 to the buffer tank 6. After the pressure buffering of the buffer tank 6, the natural gas enters the enhanced diffusion mechanism through the second gas pipe 7. The natural gas passes through the first branch pipe 9, the second branch pipe 10, the third branch pipe 11 and the fourth branch pipe 12 respectively. A part of the natural gas is directly sprayed from the first injection hole 21 on the nozzle 19, and the other part of the natural gas enters the diffusion ring 24 from the second injection hole 20, and then sprays out from the diffusion hole 25 on the diffusion ring 24, so that 8 uniform injection flames are formed. Since the gas source pressure of the natural gas is large enough, the flame sprayed in the diffusion hole 25 will not be smaller than the flame from the first injection hole 21, which can meet the needs of existing production.

[0031] When an emergency such as water or power outage occurs, in order to ensure the safety of the production system, it is necessary to drain the remaining gas source in the gas station 1 and the buffer tank 6. To this end, the inventor connected the second pressure relief pipe 13 to the first gas pipe 4 and the first pressure relief pipe 15 to the second gas pipe 7. When an emergency occurs, the first pressure relief valve 16 and the second pressure relief valve 14 can be directly opened to drain the remaining natural gas in the production system into the pressure relief tank 18, thereby ensuring production safety.
