Description

Technical Field

[0001] The utility model relates to the technical field of tail gas purification, in particular to a tail gas purification device prepared by calcining metal oxides. Background Art

[0002] Various pollutant tail gases discharged into the air during the production process of metal oxide roasting preparation will have a large amount of toxic gases and dust discharged into the atmosphere, which will pollute the air. These substances enter the human body through the respiratory tract through different pathways. Some of them cause direct harm, while others have a cumulative effect, which will more seriously endanger human health.

[0003] In the prior art, when purifying and filtering the exhaust gas prepared by roasting metal oxides, some purification devices have fewer purification layers, which may cause the leakage of some toxic gases, causing pollution and damage to the environment. Secondly, some metal oxide roasting preparations are integrated with the purification device, resulting in the inability to quickly replace and install the purification layer when it is blocked or damaged, causing the equipment to be out of service and causing large losses. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the prior art.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: an exhaust gas purification device prepared by roasting metal oxide, comprising: a shell, wherein both ends of the shell are provided with a clamping device, a transmission pipe is installed inside one end of one of the clamping devices, and an exhaust pipe is installed inside one end of the other clamping device, a filtering device is provided inside the shell, a first fixing ring is fixedly sleeved on one end of the surface of the transmission tube, and four first clamping grooves are equidistantly provided on the surface of the first fixing ring.

[0006] As a preferred embodiment, a second fixing ring is fixedly sleeved on one end of the surface of the discharge pipe, and four second clamping grooves are equidistantly formed on the surface of the second fixing ring.

[0007] As a preferred embodiment, the locking device includes a connecting tube, a limiting plate is installed at one end of the connecting tube, a closed ring is installed on one side of the limiting plate, the surface movable sleeve of the connecting tube is provided with a rotating ring, the surface movable sleeve of the closed ring is provided with a sealing ring, and four clamping columns are equidistantly installed on the inner surface of the rotating ring.

[0008] As a preferred embodiment, the other ends of the two connecting pipes are correspondingly installed at the centers of the two ends of the shell, the surfaces of the closed rings are movably embedded in the interior of one end of the transmission pipe and the discharge pipe, the surfaces of the two sealing rings are respectively attached to one end of the transmission pipe and the discharge pipe, and the surfaces of the multiple clamping columns are correspondingly movably embedded in the interior of the four first clamping grooves and the four second clamping grooves.

[0009] As a preferred embodiment, the filter device includes a first filter layer, a second filter layer is installed on one side of the first filter layer, a third filter layer is installed on one side of the second filter layer, a fourth filter layer is installed on one side of the third filter layer, and a fifth filter layer is installed on one side of the fourth filter layer.

[0010] As a preferred embodiment, the other side of the first filter layer is installed at one end inside the shell, and the other side of the fifth filter layer is installed at the other end inside the shell. The first filter layer is made of ceramic material, the second filter layer is made of activated carbon, the third filter layer is made of titanium dioxide, the fourth filter layer is made of nanomaterial, and the fifth filter layer is made of carbon fiber.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. The utility model can connect the transmission pipe in the device to the tail gas discharge of the metal oxide roasting preparation equipment to purify the tail gas. The purification layer of some purification devices is less, which may lead to the leakage of some toxic gases, causing pollution and damage to the environment. The gas is initially filtered through the first filter layer, and the ceramic material has a large surface area and is easy to form a uniform pore structure. It has excellent adsorption performance and chemical stability and can be used in harsh environments such as high temperature and high humidity. Secondly, the gas is filtered for the second time through the second filter layer. Activated carbon is a porous, high-surface-area adsorption material that can effectively adsorb volatile organic compounds and odorous gases in organic waste gas, and has good catalytic performance and chemical stability. Chemical stability, the gas is filtered three times through the third filter layer. Titanium dioxide has excellent catalytic performance and chemical stability, which can effectively degrade organic compounds in the exhaust gas. The gas is then filtered again through the fourth filter layer. Nanomaterials have a larger surface area than traditional materials and have higher efficiency and reaction rate in adsorption and catalytic reactions. Finally, the gas is further filtered through the fifth filter layer. The carbon fiber material has a large surface area, which can increase the ability to adsorb organic matter, and can achieve multi-layer filtration and purification of the exhaust prepared by the roasting of metal oxides, avoiding the problem that some purification devices have fewer purification layers, which will cause some toxic gases to leak out and cause pollution and damage to the environment.

[0013] 2. According to the utility model, when filtering and purifying the exhaust gas prepared by roasting metal oxides, a long period of filtration and purification will clog and damage the purification layer, and the filter device needs to be replaced in time. The rotating ring drives the clamping column to rotate and move along the direction of the first clamping slot and the second clamping slot until the clamping column moves out of the interior of the first fixed ring and the second fixed ring. Then, the shell is held to pull the closing ring out of the interior of the transmission pipe and the discharge pipe for replacement and installation. This can facilitate replacement and installation when the purification layer is clogged and damaged, improve work efficiency, and avoid the problem that some purification devices are integrated with the roasting preparation of metal oxides, which makes it impossible to replace and install them as soon as possible when the purification layer is clogged and damaged, resulting in equipment downtime and causing large losses.

[0030] In one embodiment, the other ends of the two connecting pipes 201 are correspondingly installed at the centers of the two ends of the shell 1, the surfaces of the closing ring 205 are movably embedded in the inside of one end of the transmission pipe 3 and the discharge pipe 4, the surfaces of the two sealing rings 206 are respectively attached to one end of the transmission pipe 3 and the discharge pipe 4, and the surfaces of the multiple clamping columns 204 are correspondingly movably embedded in the inside of the four first clamping grooves 302 and the four second clamping grooves 402.

[0031] Specifically: the connecting pipe 201, the closing ring 205, the sealing ring 206 and the clamping column 204 are fixedly connected and clamped and limited through the shell 1, the transmission pipe 3, the discharge pipe 4, the first clamping groove 302 and the second clamping groove 402, which plays the role of fixed connection and clamping limitation.

[0036] Working principle: The transmission pipe 3 in the device can be connected to the exhaust gas discharge of the metal oxide roasting preparation equipment to purify the exhaust gas. The purification layer of some purification devices is less, which may cause some toxic gases to leak out, causing pollution and damage to the environment. The gas is initially filtered through the first filter layer 501. The ceramic material has a large surface area and is easy to form a uniform pore structure. It has excellent adsorption performance and chemical stability and can be used in harsh environments such as high temperature and high humidity. Secondly, the gas is filtered for the second time through the second filter layer 502. Activated carbon is a porous, high-surface-area adsorption material that can effectively adsorb volatile organic compounds and odorous gases in organic waste gas and has good catalytic performance and chemical stability. The gas is filtered for the third time through the third filter layer 503. Titanium dioxide has excellent catalytic performance and chemical stability and can effectively degrade organic compounds in waste gas. The gas is then filtered again through the fourth filter layer 504. Nanomaterials have a larger surface area than traditional materials and have higher efficiency and reaction rate in adsorption and catalytic reactions. Finally, the gas is filtered through the fifth filter layer 505 The carbon fiber material has a large surface area, which can increase the ability to absorb organic matter, and can achieve multi-layer filtration and purification of the exhaust gas prepared by the calcination of the metal oxide, thereby avoiding the phenomenon that some purification devices have fewer purification layers, which may cause some toxic gases to leak out and cause environmental pollution and damage. However, when filtering and purifying the exhaust gas prepared by the calcination of the metal oxide, long-term filtration and purification will clog and damage the purification layer, and the filter device 5 needs to be replaced in time. By rotating the rotating ring 203, the clamping column 204 is driven to rotate and move along the direction of the first clamping groove 302 and the second clamping groove 402 until the clamping column 204 moves out of the interior of the first fixing ring 301 and the second fixing ring 401. Then, the housing 1 is grasped to pull the sealing ring 205 out of the interior of the transmission pipe 3 and the discharge pipe 4 for replacement and installation. This can facilitate replacement and installation when the purification layer is clogged or damaged, thereby improving work efficiency. It also avoids the impact of some purification devices that are integrated with the calcination of the metal oxide, which makes it impossible to quickly replace and install the purification layer when it is clogged or damaged, resulting in equipment downtime and significant losses.
