Description

Technical Field

[0001] The present application relates to the field of ceramsite proppant production, and in particular to a ceramsite proppant sintering flue gas treatment system. Background Art

[0002] Proppant refers to natural sand or artificial high-strength ceramic particles with a certain particle size and gradation. Ceramic proppant is made of bauxite through powder granulation and sintering. It has the characteristics of high temperature resistance, high pressure resistance, corrosion resistance, high strength, high conductivity, low density, low breakage rate, etc. It is the most widely used

[0003] The production steps of ceramsite proppants are generally material lifting, material weighing, loading, material mixing, mixed grinding, granulation in a granulator, sintering of proppant particles, and proppant screening. During the sintering process of ceramsite proppant particles, the ceramsite is directly placed in a rotary kiln. After being heated at a high temperature in the rotary kiln, the ceramsite is discharged from the discharge port of the rotary kiln. During the discharging process, a large amount of flue gas will be generated. A large amount of flue gas is affected by the high-temperature rising air flow, and the dust generated by sintering in the rotary kiln, the flue gas will carry a large amount of dust and float away.

[0004] When processing these dust-laden flue gases, a collection hood is usually installed at the discharge port of the rotary kiln. During the rising process of the flue gas, the flue gas is collected by the collection hood, and a filter is installed in the collection hood. The filter filters out the dust particles contained in the flue gas and then discharges the flue gas. However, since there is a lot of dust contained in the flue gas, the filtered dust is easy to adhere to the filter. If the dust accumulates for a long time, it may clog the filter and affect the filtering effect. Utility Model Content

[0005] The purpose of this application is to solve the problem raised in the above background technology that due to the large amount of dust contained in the flue gas, the filtered dust is easily attached to the filter net. The accumulation of dust for a long time may clog the filter net and affect the filtering effect. This application provides a ceramsite proppant sintering flue gas treatment system.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A ceramsite proppant sintering flue gas treatment system includes a rotary kiln, a collecting hood is installed on the discharge port of the rotary kiln, a smoke inlet pipe is fixed on the top of the collecting hood, a suction fan is installed on the smoke inlet pipe, a smoke outlet pipe is provided at one end of the smoke inlet pipe away from the collecting hood, a filtering mechanism is provided between the smoke inlet pipe and the smoke outlet pipe, and a circulation mechanism is provided between the smoke inlet pipe and the smoke outlet pipe.

[0008] By adopting the above technical solution, the flue gas is restricted by the collection hood, and then under the action of the suction fan, enters the filter mechanism from the smoke inlet pipe, passes through the filter mechanism, and is discharged from the smoke outlet pipe. At the same time, the clean water in the filter mechanism cleans the filter mechanism. When the filter mechanism filters the flue gas, the circulation mechanism is used to send clean water into the filter mechanism to replace the water in the filter mechanism, thereby filtering out dust particles in the flue gas and reducing the possibility of filtered dust particles clogging the filter mechanism.

[0009] Furthermore, the filtering mechanism includes a filter cabin arranged between the smoke inlet pipe and the smoke outlet pipe, the filter cabin is connected to the smoke inlet pipe and the smoke outlet pipe, two symmetrical support frames are fixed on the filter cabin, the support frames are in contact with the ground, a partition plate is fixed in the filter cabin, a filter disc is provided on the partition plate, the filter disc passes through the partition plate, and evenly distributed filter holes are opened on the filter disc, and a rotating component is provided between the partition plate and the filter disc.

[0010] By adopting the above technical solution, the filter disc filters the dust particles entrained in the flue gas, and at the same time, the filter disc is driven to rotate by the rotating mechanism. During the rotation of the filter disc, clean water washes away the dust on the filter disc, thereby filtering the dust particles entrained in the flue gas and cleaning the filter disc at the same time, reducing the possibility of dust particles clogging the filter disc.

[0011] Furthermore, the rotating assembly includes a rotating shaft arranged in the filter cabin, both ends of the rotating shaft are rotatably connected to the filter cabin, one end of the rotating shaft passes through the filter cabin, a rotating motor is fixed to one end of the filter cabin, a transmission belt is connected between the output end of the rotating motor and the rotating shaft, and the filter disc is fixedly connected to the rotating shaft.

[0012] By adopting the above technical solution, the output end of the rotating motor uses a transmission belt to drive the rotating shaft to rotate, and the rotating shaft drives the filter disc to rotate. The filter disc rotates between the partition plates, so that the filter disc can filter the flue gas while coming into contact with clean water for cleaning, reducing the possibility of filtered dust particles clogging the filter disc.

[0013] Furthermore, two symmetrical wiping blocks are fixed to the bottom of the partition plate, and the two wiping blocks are respectively located on both sides of the filter disc.

[0014] By adopting the above technical solution, the two wiping blocks are in contact with the filter disc. When the filter disc rotates from the bottom of the partition plate to the top of the partition plate, the two wiping blocks wipe the filter disc, thereby reducing water stains and dust particles attached to the filter disc.

[0015] Furthermore, a scraping plate is fixed on one of the wiping blocks, and the scraping plate conflicts with the filter disc.

[0016] By adopting the above technical solution, the scraping plate located on the filter surface of the filter disc further scrapes the filter disc, thereby reducing the possibility that some dust particles are still attached to the filter disc.

[0017] Furthermore, the circulation mechanism includes a sedimentation tank arranged below the filter cabin, a water outlet pipe is fixed to one end of the filter cabin away from the smoke outlet pipe, the water outlet pipe is communicated with the filter cabin, the end of the water outlet pipe away from the filter cabin is located in the sedimentation tank, and an outlet water pump is installed, and a water inlet pipe is fixed to one end of the filter cabin close to the smoke outlet pipe, the end of the water inlet pipe away from the filter cabin is located in the sedimentation tank, and an inlet water pump is installed, and the water inlet pipe is communicated with the filter cabin.

[0018] By adopting the above technical solution, the water containing dust particles in the filter cabin enters the bottom of the sedimentation tank from the outlet pipe, and then settles in the sedimentation tank. Then, the water settled in the upper part of the sedimentation tank is pumped into the filter cabin by the water inlet pipe by the water inlet pump, so that the water in the filter cabin circulates. At the same time, the water flows through the filter cabin from the direction of the water inlet pipe to the direction of the water outlet pipe, thereby reducing the dust particles washed from the filter disc from settling in the filter cabin, and at the same time increasing the fluidity of the water in the filter cabin, reducing the possibility of dust particles adhering to the filter disc.

[0019] Furthermore, a propulsion propeller is provided at one end of the filter cabin near the smoke outlet pipe, and the output end of the rotary motor passes through the filter cabin and is fixedly connected to the propulsion propeller.

[0020] By adopting the above technical solution, the rotating motor drives the propeller, which pushes the water from the direction of the water inlet pipe to the direction of the water outlet pipe, thereby increasing the impact force of the water flow on the filter disc and further reducing the possibility of dust particles adhering to the filter disc.

[0021] Furthermore, a filter screen is fixed in the sedimentation tank, the filter screen is rectangular, and the water inlet pump is located in the filter screen.

[0022] By adopting the above technical solution, the water inlet pump is placed in the filter screen, and the filter screen filters the dust particles in the sedimentation tank, thereby filtering out the dust particles in the sedimentation tank that have not been filtered in time, and reducing the possibility of dust particles in the water being sent into the filter cabin.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. The present invention is characterized in that the bottom of the filter chamber and the partition plate are filled with clean water, the ceramsite proppant is placed in a rotary kiln for drying, and the ceramsite proppant is then discharged from the discharge port of the rotary kiln. A large amount of flue gas is generated during the discharge process, and the flue gas is restricted by a collection hood. Then, under the action of a suction fan, the flue gas enters the filter chamber from the smoke inlet pipe, and then passes through the top of the partition plate. The flue gas carrying dust particles passes through the filter disc, and the filter disc filters the flue gas, and then the flue gas is discharged from the smoke outlet pipe. When the filter disc filters the dust particles, a rotating motor is started, and the output end of the rotating motor drives the rotating shaft to rotate using a transmission belt, and the rotating shaft drives the filter disc to rotate. The filter disc rotates between the partition plates, allowing the filter disc to filter the flue gas while passing through the clean water under the partition plate. The clean water rinses the filter disc, thereby achieving the purpose of being able to use the filter disc to filter dust particles in the flue gas while being able to clean the filter disc in time, reducing the possibility of dust particles clogging the filter disc, and reducing the possibility of dust particles that pass through being scattered randomly.

[0025] 2. In the present application, by simultaneously starting the outlet water pump and the inlet water pump, the water containing dust particles in the filter cabin enters the bottom of the sedimentation tank from the outlet pipe, and then settles in the sedimentation tank. Then, the inlet water pump uses the inlet pipe to send the water settled in the upper part of the sedimentation tank into the filter cabin, so that the water in the filter cabin circulates. At the same time, the water flows through the filter cabin, flowing from the direction of the inlet pipe to the direction of the outlet pipe, and the water flows to flush the filter disc, forming a cycle, thereby achieving the purpose of reducing the dust particles cleaned from the filter disc from settling in the filter cabin, and at the same time increasing the fluidity of the water in the filter cabin, reducing the possibility of dust particles adhering to the filter disc.

[0032] The following is combined with Figure 1 —4 provides further details of this application.

[0033] The embodiments of the present application disclose a ceramsite proppant sintering flue gas treatment system.

[0034] Reference Figure 1 、 Figure 2 and Figure 3 A ceramsite proppant sintering flue gas treatment system includes a rotary kiln 1, a collecting hood 2 is installed on the discharge port of the rotary kiln 1, a smoke inlet pipe 3 is fixed on the top of the collecting hood 2, a suction fan 7 is installed on the smoke inlet pipe 3, a smoke outlet pipe 4 is provided at the end of the smoke inlet pipe 3 away from the collecting hood 2, a filtering mechanism 6 is provided between the smoke inlet pipe 3 and the smoke outlet pipe 4, and a circulation mechanism 5 is provided between the smoke inlet pipe 3 and the smoke outlet pipe 4.

[0035] The ceramsite proppant is placed in the rotary kiln 1 for drying, and then the ceramsite proppant is discharged from the discharge port of the rotary kiln 1. A large amount of flue gas is generated in the process of discharging, and the flue gas is restricted by the collection hood 2. Then, under the action of the suction fan 7, the flue gas enters the filter mechanism 6 from the smoke inlet pipe 3. The flue gas passes through the filter mechanism 6 and is discharged from the smoke outlet pipe 4. At the same time, the clean water in the filter mechanism 6 cleans the filter mechanism 6. When the filter mechanism 6 filters the flue gas, the circulation mechanism 5 is used to send clean water into the filter mechanism 6 to replace the water in the filter mechanism 6. By allowing the flue gas to be treated to enter the filter mechanism 6 from the smoke inlet pipe 3, the filter mechanism 6 can use the clean water in the filter mechanism 6 to perform self-cleaning while filtering the flue gas, thereby filtering out dust particles in the flue gas and reducing the possibility of the filtered dust particles clogging the filter mechanism 6.

[0036] Reference Figure 1 、 Figure 2 and Figure 3The filtering mechanism 6 includes a filter cabin 61 arranged between the smoke inlet pipe 3 and the smoke outlet pipe 4. The filter cabin 61 is connected to the smoke inlet pipe 3 and the smoke outlet pipe 4. Two symmetrical support frames are fixed on the filter cabin 61, and the support frames are in contact with the ground. A partition plate 62 is fixed in the filter cabin 61, and a filter disc 63 is provided on the partition plate 62. The filter disc 63 passes through the partition plate 62, and the filter disc 63 is provided with evenly distributed filter holes. A rotating component 64 is provided between the partition plate 62 and the filter disc 63.

[0037] The filter chamber 61 is divided into two parts, an upper part and an lower part, by a partition plate 62, and clean water is injected under the partition plate 62. After the flue gas enters the filter chamber 61 from the smoke inlet pipe 3, the flue gas passes through the filter disc 63, and the filter disc 63 filters the dust particles contained in the flue gas. At the same time, the filter disc 63 is driven to rotate by a rotating mechanism, and the filter disc 63 brings the filtered dust particles into contact with the clean water in the filter chamber 61. During the rotation of the filter disc 63, the clean water washes away the dust on the filter disc 63. By using the filter disc 63 to filter the dust particles contained in the flue gas and allowing the filter disc 63 to move in the clean water in the filter chamber 61, the dust particles contained in the flue gas can be filtered and the filter disc 63 can be cleaned at the same time, thereby reducing the possibility of dust particles clogging the filter disc 63.

[0038] Reference Figure 2 and Figure 4 The rotating assembly 64 includes a rotating shaft 641 arranged in the filter cabin 61. Both ends of the rotating shaft 641 are rotatably connected to the filter cabin 61. One end of the rotating shaft 641 passes through the filter cabin 61. A rotating motor 642 is fixed to one end of the filter cabin 61. A transmission belt 643 is connected to the output end of the rotating motor 642 and the rotating shaft 641. The filter disc 63 is fixedly connected to the rotating shaft 641.

[0039] When the filter disc 63 filters the passing flue gas, the rotating motor 642 is started. The output end of the rotating motor 642 drives the rotating shaft 641 to rotate using the transmission belt 643. The rotating shaft 641 drives the filter disc 63 to rotate. The filter disc 63 rotates between the partition plates 62, allowing the filter disc 63 to filter the flue gas while being cleaned. By using the rotating motor 642 to drive the filter disc 63 to rotate, the filter disc 63 can filter the flue gas while coming into contact with clean water for cleaning, thereby reducing the possibility of filtered dust particles clogging the filter disc 63.

[0040] Reference Figure 1 、 Figure 2 and Figure 3 Two symmetrical wiping blocks 644 are fixed to the bottom of the partition plate 62 , and the two wiping blocks 644 are respectively located on both sides of the filter disc 63 .

[0041] Furthermore, a scraping plate 645 is fixed on one of the wiping blocks 644 , and the scraping plate 645 contacts the filter disc 63 .

[0042] The two wiping blocks 644 are made of rubber. The two wiping blocks 644 are in contact with the filter disc 63. When the filter disc 63 rotates from the bottom of the partition plate 62 to the top of the partition plate 62, the two wiping blocks 644 wipe the filter disc 63. At the same time, the scraping plate 645 located on the filtering surface of the filter disc 63 further scrapes the filter disc 63. By utilizing the wiping blocks 644 to rub the rotating filter disc 63 and the scraping plates 645 to scrape, the possibility of some dust particles adhering to the filter disc 63 after the filter disc 63 passes through the clean water under the partition plate 62 can be reduced.

[0043] Reference Figure 1 、 Figure 2 and Figure 3 The circulation mechanism 5 includes a sedimentation tank 51 arranged below the filter cabin 61. A water outlet pipe 52 is fixed to the end of the filter cabin 61 away from the smoke outlet pipe 4. The water outlet pipe 52 is connected to the filter cabin 61. The end of the water outlet pipe 52 away from the filter cabin 61 is located in the sedimentation tank 51 and is installed with a water outlet pump 54. The end of the filter cabin 61 close to the smoke outlet pipe 4 is fixed with a water inlet pipe 53. The end of the water inlet pipe 53 away from the filter cabin 61 is located in the sedimentation tank 51 and is installed with a water inlet pump 55. The water inlet pipe 53 is connected to the filter cabin 61.

[0044] When the clean water in the filter cabin 61 cleans the filter disc 63, the outlet pump 54 and the inlet pump 55 are started at the same time. The water containing dust particles in the filter cabin 61 enters the bottom of the sedimentation tank 51 from the outlet pipe 52 and then settles in the sedimentation tank 51. Then the inlet pump 55 uses the inlet pipe 53 to send the water settled in the upper part of the sedimentation tank 51 into the filter cabin 61, so that the water in the filter cabin 61 circulates. At the same time, the water flows through the filter cabin 61 from the direction of the inlet pipe 53 to the direction of the outlet pipe 52, and the water flow rinses the filter disc 63. By sending the water containing dust particles in the filter cabin 61 into the sedimentation tank 51 and then sending clean water into the filter cabin 61, it can reduce the dust particles washed from the filter disc 63 from settling in the filter cabin 61, and at the same time increase the fluidity of the water in the filter cabin 61, and reduce the possibility of dust particles adhering to the filter disc 63.

[0045] Reference Figure 1 、 Figure 2 and Figure 3 A propulsion propeller 56 is provided at one end of the filter cabin 61 close to the smoke outlet pipe 4 , and the output end of the rotary motor 642 passes through the filter cabin 61 and is fixedly connected to the propulsion propeller 56 .

[0046] While the rotating motor 642 drives the filter disc 63 to rotate, the rotating motor 642 drives the propeller 56. When the propeller 56 rotates, water is pushed from the direction of the water inlet pipe 53 to the direction of the water outlet pipe 52, thereby increasing the fluidity of the water flow. By utilizing the propeller 56 to promote the fluidity of the water flow in the filter chamber 61, the impact force of the water flow on the filter disc 63 can be increased, further reducing the possibility of dust particles adhering to the filter disc 63.

[0047] Reference Figure 1 、 Figure 2 and Figure 3 A filter screen 57 is fixed in the sedimentation tank 51 . The filter screen 57 is rectangular, and the water inlet pump 55 is located in the filter screen 57 .

[0048] The dust particles that enter the sedimentation tank 51 settle in the sedimentation tank 51, and then the water inlet pump 55 sucks the water in the upper layer of the sedimentation tank 51. The water inlet pump 55 is placed in the filter screen 57, and the filter screen 57 filters the dust particles in the sedimentation tank 51. By placing the water inlet pump 55 in the filter screen 57, the dust particles in the sedimentation tank 51 that have not been filtered in time can be filtered, thereby reducing the possibility of dust particles in the water being sent into the filter cabin 61.

[0049] Working principle: First, use the water inlet pump 55 to fill the space between the bottom of the filter cabin 61 and the partition plate 62 with clean water, put the ceramsite proppant into the rotary kiln 1 for drying, and then the ceramsite proppant is discharged from the discharge port of the rotary kiln 1. A large amount of flue gas is generated in the process of discharging. The flue gas is restricted by the collection hood 2, and then under the action of the suction fan 7, it enters the filter cabin 61 from the smoke inlet pipe 3, and then passes through the top of the partition plate 62. The flue gas carrying dust particles passes through the filter disc 63, and the filter disc 63 filters the flue gas, and then the flue gas is discharged from the smoke outlet pipe 4.

[0050] When the filter disc 63 is filtering dust particles, the rotating motor 642 is started. The output end of the rotating motor 642 drives the rotating shaft 641 to rotate via the transmission belt 643, and the rotating shaft 641 drives the filter disc 63 to rotate. The filter disc 63 rotates between the partition plates 62, allowing the filter disc 63 to filter the flue gas while passing through the clean water under the partition plates 62, and the clean water flushes the filter disc 63. At the same time, the outlet pump 54 and the inlet pump 55 are started, and the water containing dust particles in the filter cabin 61 enters the bottom of the sedimentation tank 51 through the outlet pipe 52, and then settles in the sedimentation tank 51. Then, the inlet pump 55 sends the water settled in the upper part of the sedimentation tank 51 into the filter cabin 61 via the inlet pipe 53, so that the water in the filter cabin 61 circulates. At the same time, the water flows through the filter cabin 61 and flows from the direction of the inlet pipe 53 to the direction of the outlet pipe 52, and the water flushes the filter disc 63, forming a cycle.
