Description

Technical Field

[0001] This utility model belongs to the field of kiln exhaust gas purification technology, and specifically relates to a water glass kiln exhaust gas purification device. Background Technology

[0002] Water glass, as an important inorganic chemical raw material, is widely used in various fields such as construction, casting, papermaking, and detergent manufacturing. Its production process mainly relies on water glass furnaces. Specifically, quartz sand and soda ash are mixed in a specific ratio and then fed into the water glass furnace for calcination at a high temperature of 800-1200℃, ultimately producing water glass. In this production process, water glass furnaces typically use coal, natural gas, or heavy oil as fuel, and the combustion of these fuels produces a large amount of exhaust gas.

[0003] In the current process of treating exhaust gas from water glass furnaces, if some of the particles carried in the exhaust gas are discharged directly without purification, these unpurified particulate pollutants will remain suspended in the air for a long time after being released into the atmosphere. This will not only reduce atmospheric visibility, affect transportation safety and people's daily lives, but also spread with atmospheric circulation, expand the pollution range, and have a continuous impact on regional air quality. Utility Model Content

[0004] In response to the problem that some particles carried in exhaust gas are discharged directly without purification, these unpurified particulate pollutants will remain suspended in the air for a long time after being released into the atmosphere. This not only reduces atmospheric visibility, affects transportation safety and people's daily lives, but also spreads with atmospheric circulation, expanding the pollution range and causing a continuous impact on regional air quality. This utility model proposes a water glass furnace exhaust gas purification device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0026] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0028] Please see Figures 1-6 As shown, this utility model is a water glass furnace exhaust gas purification device, including an exhaust component 1, a purification component 2 is arranged inside the exhaust component 1, a collection component 3 is arranged on the outer surface of the purification component 2, and a preheating component 4 is arranged on the outer surface of the exhaust component 1. The exhaust component 1 is used to guide the flow of water glass furnace exhaust gas, the purification component 2 is used to block particulate matter in the water glass furnace exhaust gas, the collection component 3 is used to collect particulate matter in the exhaust gas, and the preheating component 4 uses the waste heat of the exhaust gas in the exhaust component 1 to preheat the combustion air.

[0029] After the exhaust gas from the water glass furnace enters the exhaust assembly 1, it flows along the exhaust assembly 1. During the flow, the particulate matter in the exhaust gas is blocked by the purification assembly 2 inside the exhaust assembly 1, preventing the particulate matter from being discharged into the atmosphere with the exhaust gas and causing air pollution. The purification assembly 2 is activated, and the purification assembly 2 sweeps the particulate matter into the collection assembly 3, which is convenient for subsequent cleaning of the particulate matter. The water glass furnace draws in combustion air through the preheating assembly 4. After entering the preheating assembly 4, the combustion air exchanges heat with the exhaust gas in the exhaust assembly 1, preheating the combustion air and improving the fuel combustion speed.

[0030] In this invention, the exhaust assembly 1 is installed at the exhaust port of the water glass furnace, and the purification assembly 2 is located inside the exhaust assembly 1. When the exhaust gas of the water glass furnace flows in the exhaust assembly 1, it needs to pass through the purification assembly 2. The particulate matter in the exhaust gas is blocked by the mesh structure of the purification assembly 2, keeping the particulate matter inside the exhaust assembly 1 and preventing the particulate matter from entering the outside air with the exhaust gas.

[0031] In one embodiment, the smoke exhaust assembly 1 includes a first connecting pipe 101, a horizontal pipe 102 fixedly connected to the end of the first connecting pipe 101, a three-way pipe 103 fixedly connected to the end of the horizontal pipe 102, a smoke exhaust pipe 104 fixedly connected to the top of the three-way pipe 103, and a base 105 fixedly connected to the bottom of the three-way pipe 103. The first connecting pipe 101 is used to connect to the smoke outlet of the water glass furnace.

[0032] The first connecting pipe 101 is used to connect to the flue gas outlet of the water glass furnace. The exhaust gas of the water glass furnace enters the horizontal pipe 102 through the first connecting pipe 101, flows along the horizontal pipe 102 and passes through the three-way pipe 103 before being discharged from the exhaust pipe 104 above.

[0033] In one embodiment, the purification component 2 includes an intermediate pipe 201, which is fixedly installed between a three-way pipe 103 and a smoke exhaust pipe 104. A filter screen 202 is fixedly connected inside the intermediate pipe 201. A motor 203 is fixedly installed inside the base 105. A rotating shaft 204 is fixedly connected to the output shaft end of the motor 203. A mounting seat 205 is fixedly connected to the outer surface of the rotating shaft 204. A spring 206 is fixedly connected inside the mounting seat 205. A cleaning brush 207 is slidably connected inside the mounting seat 205. The cleaning brush 207 rotates on the lower surface of the filter screen 202.

[0034] When exhaust gas flows through the exhaust pipe 104, it needs to pass through the filter screen 202. The mesh structure of the filter screen 202 can block particulate matter carried in the exhaust gas, preventing the particulate matter from being discharged into the atmosphere with the exhaust gas. When the motor 203 is started, the output shaft of the motor 203 drives the rotating shaft 204 and the mounting base 205 to rotate. The mounting base 205 drives the cleaning brush 207 to rotate. The cleaning brush 207 rubs against the filter screen 202 to remove the particulate matter adhering to its surface. When it is necessary to replace the cleaning brush 207 and the filter screen 202, the filter screen 202 can be removed by removing the intermediate tube 201. At this time, the filter screen 202 no longer compresses the spring 206 through the cleaning brush 207. The spring 206 returns to its original position and pushes the cleaning brush 207 upward, so that the cleaning brush 207 separates from the mounting base 205, making it easy to replace the cleaning brush 207 and the filter screen 202.

[0035] In one embodiment, the collection component 3 includes a cover 301, which is fixedly connected to the base 105. A collection box 302 is slidably connected inside the cover 301. A guide plate 303 is fixedly connected inside the cover 301 and extends into the interior of the base 105. The rotating shaft 204 is rotatably connected to the guide plate 303.

[0036] After the cleaning brush 207 scrapes off the particles stuck to the bottom of the filter screen 202, the particles fall onto the guide plate 303 below the filter screen 202 and enter the collection box 302 inside the cover box 301 along the guide plate 303. Pulling the collection box 302 out of the cover box 301 can clean the particles inside the collection box 302.

[0037] In one embodiment, the preheating component 4 includes a bend 401, with a spiral tube 402 fixedly connected to the end of the bend 401, an air inlet pipe 403 fixedly connected to the end of the spiral tube 402, and a second connecting pipe 404 fixedly connected to the end of the air inlet pipe 403. The spiral tube 402 is wound around the outer surface of the horizontal tube 102.

[0038] The second connecting pipe 404 is connected to the air intake device. The air intake device draws in outside air through the second connecting pipe 404 and the air inlet pipe 403. The outside air enters the spiral tube 402 through the bend pipe 401 and exchanges heat with the horizontal tube 102 in the spiral tube 402 to preheat the air in the spiral tube 402. The preheated air enters the water glass furnace through the air inlet pipe 403 and the second connecting pipe 404. The opening of the bend pipe 401 faces downward to prevent rainwater from entering the bend pipe 401.

[0039] In one embodiment, for the above-mentioned exhaust pipe 104, a round rod 5 is fixedly connected to the top of the exhaust pipe 104, and a conical cap 6 is fixedly connected to the upper end of the round rod 5.

[0040] There are multiple sets of round rods 5, all of which are used to support the cone cover 6. The cone cover 6 is designed to prevent rainwater from entering the exhaust pipe 104.

[0041] In one embodiment, for the exhaust pipe 104, both the exhaust pipe 104 and the air inlet pipe 403 are equipped with brackets 7 on their outer surfaces.

[0042] The bracket 7 is used to support the exhaust pipe 104 and the air inlet pipe 403 respectively, so as to keep them stable. Other pipes can also be equipped with bracket 7.

[0043] Through the above technical solution, 1. The exhaust assembly 1 is installed at the exhaust port of the water glass furnace, and the purification assembly 2 is located inside the exhaust assembly 1. When the exhaust gas of the water glass furnace flows in the exhaust assembly 1, it needs to pass through the purification assembly 2. The particulate matter in the exhaust gas is blocked by the mesh structure of the purification assembly 2, keeping the particulate matter inside the exhaust assembly 1 and preventing the particulate matter from entering the outside air with the exhaust gas; 2. The filter screen 202 is located above the cleaning brush 207. The filter screen 202 squeezes and pushes the cleaning brush 207 to move downwards, and the cleaning brush 207 compresses the spring 206. When it is necessary to disassemble and replace the filter screen 202 and the cleaning brush 207, after removing and taking out the filter screen 202, the filter screen 202 no longer applies pressure to the cleaning brush 207 and the spring 206. At this time, the spring 206 can push the cleaning brush 207 to move upwards, making it easy to take out the cleaning brush 207 for replacement.
