Description

Technical Field

[0001] This invention relates to the field of industrial furnace and kiln technology, specifically to an industrial furnace and kiln exhaust treatment device. Background Technology

[0002] Industrial furnaces are devices used for heating, melting, or processing various substances. They are widely used in many different industries, including metallurgy, chemical industry, building materials, and glass manufacturing. The following are some common types of industrial furnaces: high-temperature furnaces, drying furnaces, combustion furnaces, smelting furnaces, glass melting furnaces, and chemical reaction furnaces. The design and operation of industrial furnaces require consideration of factors such as temperature control, energy efficiency, and waste gas treatment to ensure safe and efficient heating, melting, or processing.

[0003] Industrial furnace exhaust treatment refers to the treatment of waste gas generated in industrial furnaces to reduce environmental pollution. Below are some common industrial furnace exhaust treatment methods: desulfurization, denitrification, dust removal, VOCs treatment, flue gas deacidification, energy recovery, and monitoring and control. The appropriate treatment method must be selected based on the specific type of furnace and the composition of the waste gas, and relevant environmental protection regulations and standards must be followed.

[0004] Existing technology discloses an industrial furnace exhaust treatment device (application number CN202223084573.6), comprising an industrial furnace, an exhaust treatment box located on the right side of the furnace, an exhaust chamber located at the bottom of the furnace, an air extraction pump installed at the top of the exhaust treatment box, and exhaust pipes connected to the exhaust chamber and the top of the inner cavity of the exhaust treatment box installed on both sides of the air extraction pump. The inner cavity of the exhaust treatment box is equipped with a dust removal and filtration assembly and a desulfurization and denitrification component. This industrial furnace exhaust treatment device uses an air extraction pump to draw exhaust gas into the exhaust treatment box, where filter plates remove dust and impurities. The desulfurization and denitrification component inside the box further purifies the gas, resulting in better exhaust gas treatment. When the filter plates need cleaning, a motor can be driven to rotate the lead screw, which pushes the filter plates out for easy cleaning, making the device convenient to use and improving subsequent purification effects.

[0005] The above-mentioned waste gas is purified by filter plates and desulfurization and denitrification components. At the same time, the atomizing nozzles in the exhaust treatment box spray alkaline substances, which causes some solids to remain on the guide plate. As a result, the solids cannot be collected, and a large amount of solids clog the atomizing nozzles, thus preventing the atomizing nozzles from spraying and making it impossible to perform desulfurization and denitrification of the waste gas.

[0006] Therefore, it is necessary to design an industrial furnace exhaust treatment device that is highly practical and capable of performing desulfurization and denitrification operations on the exhaust gas inside the treatment box multiple times and for extended periods. Summary of the Invention

The connecting pipe 161 is movably connected to the upper surface of the stainless steel housing 151. The particle filter screen 162 is threaded to the stainless steel housing 151. At the upper back of the shell 151, the surface of the sealing connecting block 153 is pushed, causing the sealing connecting block 153 to move left and right, allowing it to insert into the left and right ends of the stainless steel shell 151. This makes the sealing connecting block 153 movably connected to the upper surface of the hydrogen peroxide pipe 143.

[0041] The filter device 16 includes a first connecting pipe 161, a particulate filter 162, a second connecting pipe 163, and a metal housing 164. The second connecting pipe 163 is located at the lower end of the filter device 16 and is threaded to the top surface of the metal housing 164. A hydrogen peroxide water tank 145 is movably connected to the lower surface of a stainless steel housing 151. The stainless steel housing 151 is fixedly connected to the back of a metal baffle plate 13. The metal baffle plate 13 is fixedly connected to the top surface of the metal housing 164. The metal housing 164 is threaded to the surface of the particulate filter 162. An exhaust gas discharge pipe is also included. 11 is threaded to the lower back of the furnace body 2. 12 is threaded to the lower back of the stainless steel outer shell 151. 12 is threaded to the bottom surface of the connecting pipe 163. When 12 is started, it can extract the exhaust gas generated inside the furnace body 2. The exhaust gas passes through the exhaust gas discharge pipe 11 and the exhaust fan 12, allowing it to enter the metal outer shell 164. The connecting pipe 163 inside the metal outer shell 164 can filter the particles in the exhaust gas. The metal outer shell 164 is threaded to the bottom surface of the connecting pipe 161.

[0042] In use, first hold the front end of the hydrogen peroxide tank 145 and push it backward to insert it into the lower end of the stainless steel casing 151, making the surface of the hydrogen peroxide tank 145 connected to the inner surface of the lower end of the stainless steel casing 151. Then, hold the surface of the limiting metal plate 141 and push it left and right, causing the limiting metal plate 141 to push the hydrogen peroxide pipe 143 left and right, making the limiting metal plate 141 connected to the surface of the stainless steel casing 151. The limiting metal plate 141 can also push the hydrogen peroxide pipe 143 left and right, which in turn pushes the water pump 144 left and right. The limiting metal plate 141 and the stainless steel casing 151 are now connected. Simultaneously, the hydrogen peroxide pipe 143 is inserted into the left and right ends of the stainless steel casing 151, so that the hydrogen peroxide pipe 143 and the left and right end surfaces of the stirring plate 1421 are inserted and fixed, thereby limiting and fixing the position of the stirring plate 1421. This allows the water pump 144 and the top surface of the hydrogen peroxide tank 145 to be threadedly connected. Then, the surface of the sealing block 153 is pushed, causing the sealing block 153 to move left and right, allowing it to be inserted into the left and right ends of the stainless steel casing 151. This allows the sealing block 153 to be movably connected to the upper surface of the hydrogen peroxide pipe 143, thereby limiting and fixing the position of the hydrogen peroxide pipe 143. At the same time, the sealing block 153 and the stainless steel threaded rod 1422... The surface is fixed by insertion, thereby limiting and fixing the position of the solid object scraper 1424. Then, material is placed into the furnace body 2, allowing the heating component 5 on the top surface of the furnace body 2 to perform a firing operation on the material inside the furnace body 2, generating sulfur-containing waste gas inside the furnace body 2. The exhaust fan 12 is started, which extracts the waste gas generated inside the furnace body 2, allowing the waste gas to pass through the waste gas discharge pipe 11 and the exhaust fan 12, so that the waste gas enters the metal shell 164. The connecting pipe 163 inside the metal shell 164 can filter the particles in the waste gas. At the same time, the water pump 144 is started, which extracts hydrogen peroxide from the hydrogen peroxide tank 145, allowing the hydrogen peroxide to pass through the hydrogen peroxide tank 145. Hydrogen peroxide enters the desulfurization plate 142 through hydrogen peroxide pipe 143, allowing the stirring plate 1421 inside the desulfurization plate 142 to spray hydrogen peroxide. Meanwhile, the waste gas, filtered by connecting pipe two 163, enters the stainless steel outer shell 151 through connecting pipe one 161. The filtered waste gas drives the stirring plate 1421 to rotate clockwise or counterclockwise. When the stirring plate 1421 rotates, centrifugal force is generated inside, causing the hydrogen peroxide inside the stirring plate 1421 to be sprayed, creating hydrogen peroxide water mist inside the upper part of the stainless steel outer shell 151. The hydrogen peroxide inside the upper part of the stainless steel outer shell 151 neutralizes the filtered waste gas, thereby solidifying the sulfur-containing substances in the filtered waste gas.This causes solid matter to fall onto the surface of the filter plate 154. When the stirring plate 1421 rotates, it drives the conveyor belt 1425 to rotate. The conveyor belt 1425 drives the stainless steel threaded rod 1422 to rotate, and the stainless steel threaded rod 1422 drives the metal connecting block 1423 to move left and right. The metal connecting block 1423 can scrape off the solidified matter on the surface of the filter plate 154, preventing the surface of the filter plate 154 from being blocked by sulfur-containing solidified matter. This allows the desulfurization plate 142 inside the stainless steel outer shell 151 to desulfurize the exhaust gas, thus ensuring that the exhaust gas is free of sulfides.
