Description

Technical Field

[0001] This utility model relates to the technical field of gas combustion, and in particular to a combustion device for acidic gases. Background Technology

[0002] Due to the corrosive and toxic nature of acidic gases (such as hydrogen sulfide), their combustion safety is a key technical point that needs to be controlled in industrial incinerators (or combustion furnaces).

[0003] Traditionally, the solution to the problem of complete combustion of acidic gases is to increase the combustion temperature and extend the flue gas residence time (i.e., increase the size of the incinerator). However, the above methods require increasing the size of the incinerator, thereby increasing the cost of the incinerator. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a combustion device for acidic gases, which uses refractory bricks for insulation to reduce the size of the incinerator and thus reduce the cost of the incinerator.

[0006] To achieve the above objectives, this utility model proposes a combustion device for acidic gas, comprising a natural gas transmission device, an incinerator, a spray gun, an igniter, and multiple refractory bricks. The incinerator contains a partition block, a mounting frame, and a gas transmission pipe. The partition block has mounting holes, dividing the incinerator into an installation section and a combustion section. The mounting frame is located within the installation section, with one end connected to the incinerator and the other end connected to the mounting holes. The gas transmission pipe is mounted on the mounting frame, with one end connected to an air inlet on the incinerator and the other end connected to the combustion section. The spray gun is mounted on the incinerator and connected to the mounting frame, and has an acidic gas inlet pipe and an acidic gas outlet pipe connected to the combustion section. The igniter is mounted on the partition block and located within the combustion section, with the gas inlet of the natural gas transmission device located to one side of the igniter. Multiple refractory bricks are respectively arranged within the incinerator and located within the combustion section.

[0007] This invention relates to a combustion device for acidic gases, which uses refractory bricks for insulation, reducing the size of the incinerator and thus lowering its cost.

[0008] In addition, the acid gas combustion device proposed above according to this application may also have the following additional technical features:

[0009] Specifically, the acid gas outlet pipe is equipped with swirl vanes.

[0010] Specifically, multiple refractory bricks are laid around the incinerator, with the thickness of the bricks laid closer to the separator being greater than the thickness of the bricks laid further away from the separator.

[0011] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0012] The above and / or additional aspects and advantages of this utility model will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, in which:

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The combustion device for acidic gas according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0017] like Figure 1 As shown, the acid gas combustion device of this utility model embodiment may include natural gas transmission equipment, incinerator 1, spray gun 2, igniter 3 and multiple refractory bricks 4.

[0018] The incinerator 1 is equipped with a partition block 10, a mounting frame 11 and a gas delivery pipe 12.

[0019] The partition block 10 has mounting holes, and the partition block 10 divides the incinerator 1 into an installation part 100 and a combustion part 101;

[0020] Mounting bracket 11 is located inside mounting section 100. One end of mounting bracket 11 is connected to incinerator 1, and the other end of mounting bracket 11 is connected to mounting hole. Gas delivery pipe 12 is mounted on mounting bracket 11. One end of gas delivery pipe 12 is connected to air inlet 13 on incinerator 1, and the other end of gas delivery pipe 12 is connected to combustion section 101. Spray gun 2 is mounted on incinerator 1 and connected to mounting bracket 11. Acid gas inlet pipe 20 and acid gas outlet pipe 21 are provided on spray gun 2. Acid gas outlet pipe 21 is connected to combustion section 101.

[0021] It should be noted that the acid gas inlet pipe 20 described in this embodiment is connected to acid gas, thereby ensuring that the acid gas is ejected from the spray gun 2.

[0022] It should be noted that when the gas delivery pipe 12 described in this embodiment sprays acidic gas into the combustion section 101 from the spray gun 2, a negative pressure is generated around the acidic gas outlet pipe 21, thereby transporting external air into the combustion section 101 through the air inlet 13 and the gas delivery pipe 12, thus ensuring the combustion effect of the acidic gas in the combustion section 101.

[0023] It should be noted that the gas delivery pipe 12 described in this embodiment is an annular pipe, which allows air to enter from all sides of the acid gas outlet pipe 21, thereby ensuring the mixing effect of air and acid gas.

[0024] It is understandable that introducing air ensures that oxygen is supplied for combustion within the combustion section 101, thereby ensuring the combustion effect of the acidic gas within the combustion section 101.

[0025] Igniter 3 is mounted on partition block 10 and located within combustion section 101, with the gas inlet of natural gas transmission equipment located on one side of igniter 3.

[0026] It can be understood that by setting up the igniter 3, the natural gas introduced into the combustion section 101 can be ignited, thereby burning and decomposing the acidic gas.

[0027] Multiple refractory bricks 4 are respectively placed inside the incinerator 1 and located at the combustion section 101.

[0028] It is understandable that by setting the refractory bricks 4, the refractory bricks 4 are heated while the combustion part 101 is burning. The heated refractory bricks 4 have a certain heat preservation effect, so that the incinerator 1, which is far from the ignition point, still has a certain combustion temperature. Therefore, it is not necessary to increase the combustion temperature of the incinerator 1 or increase the size of the incinerator 1, thereby reducing the cost of the combustion device.

[0029] It should be noted that the refractory brick 4 described in this embodiment is a common component on the market and is existing technology; therefore, it will not be described in detail here.

[0030] Specifically, during actual operation, relevant personnel operate the controller (not shown in the figure), the controller sends a control signal to control the natural gas transmission equipment to deliver natural gas to the combustion section 101, and the igniter 3 ignites the natural gas. At this time, the natural gas burns in the combustion section 101, continuously heating multiple refractory bricks 4, and the oxygen required for combustion is delivered to the combustion section 101 through the air inlet 13 and the gas transmission pipe 12.

[0031] When the spray gun 2 is in operation, it draws in acidic gas from the acidic gas inlet pipe 20 and discharges it from the acidic gas outlet pipe 21. The acidic gas is then discharged to the combustion section 101 for combustion, thereby achieving complete combustion of the acidic gas. In addition, the refractory brick 4 has the effect of heat transfer and heat preservation, so that the acidic gas, which is far from the ignition point, still has a sufficient temperature for complete combustion. Therefore, it is not necessary to increase the combustion temperature of the incinerator 1 or increase the size of the incinerator 1, thereby reducing the cost of the combustion device.

[0032] In one embodiment of this utility model, such as Figure 1 As shown, the acid gas outlet pipe 21 is rotatably equipped with swirl vanes 22.

[0033] Understandably, by setting the knob blades, when acidic gas is ejected from the acidic gas outlet pipe 21, it impacts the knob blades, causing the knob blades to rotate. The rotation of the swirling blades 22 can drive the acidic gas to spread in all directions and prevent the acidic gas from being ejected directly into the outlet (not shown in the figure), thereby improving the complete combustion effect of the acidic gas.

[0034] In one embodiment of this utility model, such as Figure 1 As shown, multiple refractory bricks 4 are laid around the incinerator 1, and the thickness of the bricks laid on the side closer to the partition block 10 is greater than the thickness of the bricks laid on the side farther away from the partition block 10.

[0035] It is understandable that the thickness of the multiple refractory bricks 4 laid on the side closer to the separator 10 is greater than the thickness of the side farther away from the separator 10, so that the combustion section 101 forms an involute shape, ensuring that when the acid gas outlet pipe 21 is discharged, the concentration of acid gas is high, the refractory bricks 4 gather, and the acid gas burns in large quantities when discharged.

[0036] In summary, the acid gas combustion device of this utility model uses refractory bricks for insulation, which reduces the size of the incinerator and thus lowers the cost of the incinerator.
