Description

Technical Field

[0001] This utility model belongs to the field of sulfur combustion furnace technology, and in particular relates to a horizontal sulfur combustion furnace with high yield. Background Technology

[0002] A horizontal sulfur combustion furnace is a device used to burn sulfur to produce sulfur dioxide gas. The combustion chamber is usually a horizontal cylindrical container with a sulfur feed inlet at one end and a sulfur dioxide gas outlet at the other. An air inlet is located on the side and connected to the furnace wall. After the air enters the sulfur combustion furnace, it mixes and burns with sulfur vapor to produce sulfur dioxide gas, which is then transported to the equipment in use. However, it still has the following drawbacks in actual use:

[0003] 1. During operation, air is supplied to the horizontal sulfur combustion furnace through a single air inlet. When the internal environment is overheated and the air input is limited, it mixes with sulfur vapor. During the mixing process of air and sulfur vapor, it takes a longer time to mix evenly and burn completely.

[0004] 2. Secondly, after the sulfur combustion furnace burns, when the mixed gas after combustion is directly discharged, some sulfur vapor remains. When it is directly discharged to the equipment, the sulfur vapor does not react completely, resulting in a low final sulfur dioxide recovery rate. Utility Model Content

[0005] The purpose of this utility model is to provide a horizontal sulfur combustion furnace with high yield. By setting an outer fixed sleeve, a conveying component and a transfer chamber, the problem of insufficient sulfur vapor reaction and low sulfur dioxide yield in the horizontal sulfur combustion furnace is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a horizontal sulfur combustion furnace with high yield, comprising an outer fixed sleeve, a conveying assembly, and a transfer chamber. The inner wall of the outer fixed sleeve is fixed with equidistantly distributed partition rings. An inner sleeve is fixed to the inner ring of all the partition rings. Air inlets are arranged in a ring array on the periphery of the inner sleeve between adjacent partition rings. A conveying assembly is provided at one end of the outer fixed sleeve. The conveying assembly includes a conveying sleeve, a heat-conducting plate, and a thermal switch. A heat-conducting plate is fixed to the periphery of the conveying sleeve, and a thermal switch is fixed to the side of the heat-conducting plate away from the conveying sleeve. The end of the conveying sleeve away from the outer fixed sleeve is fixedly connected to the transfer chamber. During operation, the inner sleeve is fixed within the partition rings on the inner wall of the outer fixed sleeve. The inner sleeve provides a combustion chamber for sulfur vapor combustion. During operation, the conveying assembly transports the pre-combustion products through this chamber, adjusts the temperature appropriately, and further combusts them before conveying them to the transfer chamber for transfer, thereby increasing the yield of sulfur dioxide after combustion.

[0008] Furthermore, a sealing disc is fixed to one end of the outer fixed sleeve away from the conveying assembly. A steam pipe is fixed through the sealing disc along the central axis. The sealing disc is fixed to the inner sleeve. When the outer fixed sleeve is working, the sealing disc seals one end of the outer fixed sleeve and the inner sleeve.

[0009] Furthermore, an air inlet pipe with equal spacing is fixed through the periphery of the outer fixed sleeve. One end of the air inlet pipe near the central axis of the outer fixed sleeve is located between two adjacent partition rings. When the outer fixed sleeve is working, compressed air is delivered to the space between the inner sleeve and the outer fixed sleeve through the air inlet pipe.

[0010] Furthermore, the conveying assembly also includes a cooling jacket, a water supply pipe, and an electrically controlled valve. The two edges of the cooling jacket are fixedly connected to the water supply pipes, and the two water supply pipes are fixedly connected to the electrically controlled valves. When the conveying assembly is working, the cooling water passing through the cooling jacket cools the conveying jacket and the mixture of sulfur vapor that has undergone preliminary combustion, ensuring that the temperature difference during combustion of the mixture is within a suitable range.

[0011] Furthermore, the conveying assembly also includes a second sealing disc. The cooling sleeve is fixed around the periphery of the conveying sleeve and is positioned close to the outer fixed sleeve. The heat-conducting sheet is positioned away from the outer fixed sleeve. The second sealing disc is fixed at the edge of the conveying sleeve near the outer fixed sleeve. The second sealing disc is fixed at the end of the outer fixed sleeve and the inner sleeve away from the first sealing disc. When the conveying assembly is in operation, the second sealing disc seals the end of the outer fixed sleeve and the inner sleeve away from the first sealing disc.

[0012] Furthermore, an exhaust pipe is fixedly connected to the center of the end of the transfer chamber away from the conveying component. The inner diameter of the exhaust pipe is larger than the inner diameter of the inlet pipe. When the transfer chamber is working, the mixed gas transferred therein is discharged into the equipment through the exhaust pipe.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model solves the problem of insufficient sulfur vapor reaction in horizontal sulfur combustion furnaces by setting an outer fixed sleeve. Sulfur vapor above the ignition point is transported to the inner sleeve through a steam pipe, while compressed steam from external equipment is transported to the outer fixed sleeve through an air inlet pipe. After being separated by a partition ring, the steam is transported to the inner sleeve through an air inlet hole. When the sulfur vapor above the ignition point comes into contact with air, it burns. During the combustion process, the sulfur vapor continuously comes into contact with fresh air, which makes the sulfur vapor burn more completely. The fully burned sulfur vapor is then transported to the conveying sleeve, making the sulfur vapor in the sulfur combustion furnace burn more completely.

[0015] 2. This utility model solves the problem of insufficient sulfur dioxide recovery rate in horizontal sulfur combustion furnaces by setting an outer fixed sleeve, a conveying component, and a transfer chamber. The sulfur vapor and air mixture after preliminary combustion in the inner sleeve is conveyed through the conveying sleeve. When the temperature of the conveying sleeve is above a certain degree, the heat is transferred to the heat-conducting plate through the conveying sleeve and then to the thermal switch. The thermal switch opens two electrically controlled valves, and cooling water enters the cooling sleeve from a water supply pipe. The cooling water flows in the cooling sleeve to cool down the residual sulfur vapor and sulfur dioxide gases after combustion that have passed through the conveying sleeve, preventing excessive sublimation of sulfur. After adjustment and further combustion by the conveying sleeve, the sulfur vapor is more fully converted into sulfur dioxide gas, ensuring that the combustion temperature range is controllable. After combustion, the mixed gas enters the transfer chamber for transfer and is then input into the equipment used through the exhaust pipe, resulting in a higher sulfur dioxide recovery rate in the horizontal sulfur combustion furnace.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0026] Please see Figure 1-3 This utility model relates to a horizontal sulfur combustion furnace with high yield, comprising an outer fixed sleeve 1, a conveying assembly 2, and a transfer chamber 3. The inner wall of the outer fixed sleeve 1 is fixed with equally spaced partition rings 106, which stably fix the inner sleeve 104 within the outer fixed sleeve 1 and separate the air entering the outer fixed sleeve 1, allowing it to be separately conveyed into the inner sleeve 104. The inner sleeve 104 is fixed to the inner ring of all the partition rings 106, providing space for sulfur vapor combustion. Air inlets 105 are arranged in a ring array on the periphery of the inner sleeve 104 between adjacent partition rings 106, conveying the air entering between the inner sleeve 104 and the outer fixed sleeve 1 into the inner sleeve 104. A conveying assembly 2 is provided at one end of the outer fixed sleeve 1. During operation, the conveying assembly 2 conveys the air that has passed through the initial... The sulfur vapor is transferred and transported in a step-by-step combustion process, which allows the sulfur vapor to be further combusted and increases the completeness of combustion. The transport assembly 2 includes a transport sleeve 204, a heat-conducting plate 205, and a thermal switch 206. The heat-conducting plate 205 is fixed around the periphery of the transport sleeve 204, and the thermal switch 206 is fixed on the side of the heat-conducting plate 205 away from the transport sleeve 204. The transport sleeve 204 is connected to the thermal switch 206 through the heat-conducting plate 205. The heat on the transport sleeve 204 is transferred to the thermal switch 206 through the heat-conducting plate 205. When the temperature on the transport sleeve 204 rises to above 350 degrees, the thermal switch 206 opens, and two electric control valves 203 open. The end of the transport sleeve 204 away from the outer fixed sleeve 1 is fixedly connected to the transfer chamber 3. The sulfur dioxide gas generated after combustion in the transport sleeve 204 is further transferred through the transfer chamber 3.

[0027] Specifically, a sealing disc 102 is fixed to the end of the outer fixed sleeve 1 away from the conveying component 2. A steam pipe 103 is fixed through the sealing disc 102 along the central axis. The sealing disc 102 is fixed to the inner sleeve 104. The outer fixed sleeve 1 closes the end away from the conveying component 2 through the sealing disc 102. The end of the steam pipe 103 away from the sealing disc 102 is connected to the equipment for conveying sulfur vapor, so that sulfur vapor exceeding the ignition point is conveyed to the inner sleeve 104.

[0028] Furthermore, an air inlet pipe 101 with equal spacing is fixed through the periphery of the outer fixed sleeve 1. The end of the air inlet pipe 101 near the central axis of the outer fixed sleeve 1 is located between two adjacent partition rings 106, and the end of the air inlet pipe 101 away from the outer fixed sleeve 1 is connected to the equipment for conveying compressed air, so that each space between the outer fixed sleeve 1 and the inner sleeve 104 separated by the partition ring 106 has a separate air inlet passage.

[0029] The operation process of this embodiment is as follows: sulfur vapor with an ignition point above the specified value is transported to the inner sleeve 104 through the steam pipe 103, and compressed air from the external equipment is transported to the outer fixed sleeve 1 through the air inlet pipe 101. After being separated by the partition ring 106, the compressed air is transported to the inner sleeve 104 through the air inlet hole 105. When the sulfur vapor with an ignition point above the specified value comes into contact with the air, it burns. During the combustion process of the sulfur vapor, it continuously comes into contact with fresh air, which makes the sulfur vapor burn more completely. The sulfur vapor is then transported to the conveying sleeve 204 after it has been fully burned. Specific Implementation Example 2

[0031] Please see Figure 1 , 2 4, 5. Based on the specific embodiment 1, the conveying component 2 also includes a cooling jacket 201, a water supply pipe 202 and an electric control valve 203. The two edges of the cooling jacket 201 are fixedly connected to the water supply pipe 202, and the two water supply pipes 202 are fixedly connected to the electric control valve 203. When the conveying component 2 is working, one water supply pipe 202 is connected to the pipeline for conveying cooling water, and the other is connected to the pipeline for circulating cooling water. After the electric control valve 203 is opened, the cooling water passes through the cooling jacket 201 to cool the cooling jacket 201.

[0032] Specifically, the conveying assembly 2 also includes a second sealing disc 207, a cooling sleeve 201 fixed around the conveying sleeve 204, and the cooling sleeve 201 is positioned close to the outer fixed sleeve 1. The heat-conducting sheet 205 is positioned away from the outer fixed sleeve 1. The second sealing disc 207 is fixed at the edge of the conveying sleeve 204 near the outer fixed sleeve 1. The second sealing disc 207 is fixed at the end of the outer fixed sleeve 1 and the inner sleeve 104 away from the first sealing disc 102. The cooling sleeve 201 is fixed to the end of the outer fixed sleeve 1 and the inner sleeve 104 away from the first sealing disc 102 through the second sealing disc 207, thus sealing the outer fixed sleeve 1.

[0033] Furthermore, an exhaust pipe 301 is fixedly connected to the center of the transfer chamber 3 away from the conveying component 2. The end of the exhaust pipe 301 away from the transfer chamber 3 is connected to the equipment using sulfur dioxide. The inner diameter of the exhaust pipe 301 is larger than the inner diameter of the inlet pipe 101. When the transfer chamber 3 is working, the sulfur dioxide pipeline after transfer in the transfer chamber 3 is discharged to the equipment using sulfur dioxide through the exhaust pipe 301.

[0034] The operation process of this embodiment is as follows: During operation, the sulfur vapor and air mixture after initial combustion in the inner sleeve 104 is conveyed through the conveying sleeve 204. When the temperature of the conveying sleeve 204 exceeds 350 degrees Celsius, the heat is transferred through the conveying sleeve 204 to the heat-conducting plate 205, and then through the heat-conducting plate 205 to the thermal switch 206. The thermal switch 206 opens two electrically controlled valves 203, and cooling water enters the cooling sleeve 201 from a water supply pipe 202. The cooling sleeve 201 flows to cool down the residual sulfur vapor and sulfur dioxide gases after combustion in the conveying sleeve 204, preventing excessive sublimation of sulfur. After adjustment and further combustion in the conveying sleeve 204, the sulfur vapor is more fully converted into sulfur dioxide gas, ensuring that the combustion temperature range is controllable. After combustion, the mixture enters the transfer chamber 3 for transfer and is then input into the equipment being used through the exhaust pipe 301.
