Description

Technical Field

[0001] This application relates to the field of industrial manufacturing technology, and in particular to an industrial flue gas environmental protection treatment and separation device. Background Technology

[0002] Industrial flue gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within a factory premises. These waste gases include carbon dioxide, carbon disulfide, carbon monoxide, soot, and industrial dust. Direct emission of these gases would cause significant environmental pollution. Therefore, environmentally friendly separation devices are needed to pre-treat industrial flue gas, i.e., to separate solid particles such as dust from it. Currently, a common and cost-effective method is the cyclone separator. The industrial flue gas enters the separator tangentially along the inlet pipe and moves downwards in a spiral motion to achieve gravity separation. The dust particles in the flue gas automatically settle, while the gas is discharged upward along the center of the separator, thus achieving dust treatment and separation of the flue gas. However, the fixed dust particles mixed in the industrial flue gas have different sizes. Some smaller dust particles do not settle sufficiently due to gravity and are prone to forming an upward floating reaction force, which generates a reaction force on the spiral airflow entering the separator, reducing the separation efficiency and quality of the device. Therefore, it is urgent to design an industrial flue gas environmental protection treatment and separation device to increase the individual volume and mass of the dust particles in the flue gas to overcome the above-mentioned potential defects. Summary of the Invention

[0003] This application proposes an industrial flue gas environmental protection treatment and separation device, which has the advantages of high dust collection and separation efficiency, and is used to solve the problem of low gravity settling efficiency of small-volume dust particles in the prior art.

[0004] To achieve the above objectives, this application adopts the following technical solution: an industrial flue gas environmental protection treatment and separation device, comprising a cyclone separator, an exhaust pipe installed on the top of the cyclone separator, an air inlet pipe installed on the outer surface of the cyclone separator, and an air inlet pipe having the following installed inside the air inlet pipe:

[0005] A water supply mechanism, comprising a water tank and a connecting pipe fixedly installed on the top of the air inlet pipe, one end of the connecting pipe passing through the inner cavity of the water tank, and the other end of the connecting pipe passing through the interior of the air inlet pipe;

[0006] The water discharge mechanism includes two sets of fixed columns and a support ring fixedly installed on the inner wall of the air inlet pipe. A water discharge cylinder is rotatably installed inside the support ring. The water discharge cylinder is connected to a connecting pipe. Multiple sets of drain pipes are fixedly connected to the left and right sides of the outer surface of the water discharge cylinder. A dispersion block is fixedly connected to one end of the outlet of the drain pipe. The outlet of the drain pipe faces away from the air inlet direction of the air inlet of the air inlet pipe. Two sets of fan blades are fixedly installed at equal intervals on the upper and lower circumferences of the outer surface of the water discharge cylinder.

[0007] Furthermore, the water supply mechanism also includes a telescopic rod fixedly installed on the top of the air inlet pipe. The telescopic rod is located in front of the water tank, and a water inlet is provided on the top of the water tank. A wooden plug is fixedly connected to the telescopic end of the telescopic rod, and the bottom of the wooden plug is adapted to be snapped into the inner wall of the water inlet, forming a seal with the water inlet.

[0008] Furthermore, a fixing cylinder is fixedly installed on the inner wall of the air intake pipe, and a spiral strip is fixedly connected inside the fixing cylinder. The support ring is fixedly connected to the fixing column.

[0009] Furthermore, a connecting tube is movably sleeved on the rear side of the inner wall of the water discharge tube, and a sealing ring is glued to the outer surface of the connecting tube. The sealing ring is made of rubber block and is interference-fitted with the inner wall of the water discharge tube. The bottom end of the connecting tube is fixedly connected to the connecting tube.

[0010] Furthermore, the length of the fan blades is less than the length of the water discharge cylinder, and the fan blades are generally distributed at an angle on the outer surface of the water discharge cylinder.

[0011] Furthermore, a sealing cylinder is fixedly installed on the front side of the inner wall of the water discharge cylinder. A spring and a sealing column are movably connected inside the sealing cylinder. The sealing column is elastically supported on the inner wall of the sealing cylinder by the spring. A sealing block is glued to the rear end of the sealing column, and the sealing block abuts against the connecting cylinder.

[0012] Furthermore, the axial cross-sectional shape of both the connecting cylinder and the sealing column is "T" shaped, the connecting cylinder is hollow, and the sealing block is made of rubber.

[0013] Furthermore, the wooden plug is pushed upward by the telescopic rod when the device is in operation, thereby opening the water inlet.

[0014] Furthermore, each group contains four drain pipes, which are linearly and equidistantly distributed along the axis of the drain cylinder.

[0015] This application provides an industrial flue gas environmental protection treatment and separation device, which has the following effects:

[0016] 1. This device features a redesigned internal air inlet pipe, incorporating the concept of water vapor agglomerating solid particles. This is achieved primarily through a water discharge cylinder located inside the air inlet pipe, which is the essential passageway for flue gas. Multiple sets of drain pipes are installed on the outer surface of the water discharge cylinder. A connecting cylinder, movably fitted to the rear of the inner wall of the water discharge cylinder, connects the water discharge cylinder to the inner cavity of the water tank, providing a continuous supply of water to the water discharge cylinder. During operation, the flue gas flowing through the drain pipe opening creates a negative pressure on the inner walls of the water discharge cylinder, connecting pipe, and water tank, thereby drawing the supplementary water out of the drain pipe. Through high-temperature heating, water vapor is formed inside the air inlet pipe to capture solid dust particles. During this process, small solid particles in the flue gas are adsorbed by the water vapor, forming larger solid particles. This significantly improves the gravity settling efficiency of dust in the flue gas within the cyclone separator, thereby significantly enhancing the dust collection and separation efficiency of the device.

[0017] 2. This device also places the water supply mechanism at the top of the air inlet pipe, using a connecting pipe to connect the inner cavity of the water tank and the water outlet cylinder. Through the connecting pipe, clean water is continuously replenished into the water outlet cylinder. Due to the inclined design of the drain pipe, when the flue gas passes through its opening, a negative pressure is formed in the inner cavity of the drain pipe and the water outlet cylinder, which drives the sealing column and sealing block backward, opening the connecting pipe. The negative pressure generated draws the replenished water from the water tank into the inner cavity of the water outlet cylinder. At this time, the height difference between the upper and lower ends of the connecting pipe creates a siphon effect inside the entire connecting pipe. At this time, the water flow does not consume additional energy, and the water pressure will also push the sealing block and sealing column forward to ensure sufficient water supply, greatly improving the reliability of the device.

[0018] 3. This device utilizes a sealing cylinder, spring, and sealing column located inside the water discharge cylinder to achieve semi-automatic opening and closing of the water supply mechanism. The sealing column is elastically supported on the inner wall of the sealing cylinder by the spring and drives the sealing block to abut against the opening of the connecting cylinder. This design can prevent the replenished water from the connecting pipe from flowing downwards without restriction. Then, a set of rings is set on the outer side of the rear end of the sealing column. The rings are fixedly installed on the inner wall of the water discharge cylinder, so that the sealing column and sealing block act as pistons. When the drain pipe is subjected to negative pressure by flue gas, the sealing column drives the sealing block to move forward relative to the rings and gradually move away from the rings. Then, negative pressure is formed in the connecting pipe and the connecting cylinder, thereby absorbing the replenished water in the water tank. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0032] Example 1

[0033] Please see Figures 1-9This invention discloses an industrial flue gas environmental protection treatment and separation device, including a cyclone separator 1, an exhaust pipe 2 installed on the top of the cyclone separator 1, an air inlet pipe 3 installed on the outer surface of the cyclone separator 1, and the interior of the air inlet pipe 3 is equipped with:

[0034] Water supply mechanism 4 includes a water tank 41 and a connecting pipe 44 fixedly installed on the top of the air inlet pipe 3. One end of the connecting pipe 44 passes through the inner cavity of the water tank 41, and the other end of the connecting pipe 44 passes through the interior of the air inlet pipe 3.

[0035] The water discharge mechanism 7 includes two sets of fixed columns 71 and a support ring 72 fixedly installed on the inner wall of the air inlet pipe 3. A water discharge cylinder 73 is rotatably installed inside the support ring 72. The water discharge cylinder 73 is connected to the connecting pipe 44. Multiple sets of drain pipes 711 are fixedly connected to the left and right sides of the outer surface of the water discharge cylinder 73. A dispersion block 712 is fixedly connected to one end of the outlet of the drain pipe 711. The outlet of the drain pipe 711 faces away from the air inlet direction of the air inlet of the air inlet pipe 3. Two sets of fan blades 74 are fixedly installed at equal intervals on the upper and lower circumferences of the outer surface of the water discharge cylinder 73.

[0036] This device redesigns the interior of the intake pipe 3, introducing the concept of water vapor agglomerating solid particles. This is mainly achieved through a water discharge cylinder 73 located inside the intake pipe 3, which is the inevitable path for flue gas. Multiple sets of drain pipes 711 are installed on the outer surface of the water discharge cylinder 73. A connecting cylinder 79, which is movably sleeved on the rear side of the inner wall of the water discharge cylinder 73, connects the inner cavity of the water discharge cylinder 73 and the water tank 41, and provides a continuous supply of water to the water discharge cylinder 73. During operation, the flue gas flowing through the opening of the drain pipe 711 creates a negative pressure on the inner walls of the water discharge cylinder 73, the connecting pipe 44, and the water tank 41, thereby drawing the supplementary water out of the drain pipe 711. Through high-temperature heating, water vapor is formed in the inner cavity of the intake pipe 3 to capture solid dust particles. During this process, small solid particles in the flue gas are adsorbed by the water vapor, thus forming large solid particles. This greatly improves the gravity settling efficiency of dust in the flue gas inside the cyclone separator 1, significantly improving the dust collection and separation efficiency of the device.

[0037] Example 2

[0038] The water supply mechanism 4 also includes a telescopic rod 42 fixedly installed on the top of the air inlet pipe 3. The telescopic rod 42 is located in front of the water tank 41. A water inlet 45 is opened on the top of the water tank 41. A wooden plug 43 is fixedly connected to the telescopic end of the telescopic rod 42. The bottom of the wooden plug 43 is adapted to be snapped into the inner wall of the water inlet 45 and forms a seal with the water inlet 45.

[0039] This device also places the water supply mechanism 4 at the top of the air inlet pipe 3, and uses the connecting pipe 44 to connect the inner cavity of the water tank 41 and the water discharge cylinder 73. The connecting cylinder 79 connects the two, and continuously replenishes clean water into the interior of the water discharge cylinder 73. Due to the inclined design of the drain pipe 711, when the flue gas passes through its opening, a negative pressure is formed in the inner cavity of the drain pipe 711 and the water discharge cylinder 73, which drives the sealing column 77 and the sealing block 78 backward, opening the connecting cylinder 79. The generated negative pressure draws the replenished water in the water tank 41 into the inner cavity of the water discharge cylinder 73. At this time, the height difference between the upper and lower ends of the connecting pipe 44 forms a siphon effect inside the entire connecting pipe 44. At this time, the water flow does not consume additional energy, and the water pressure will also push the sealing block 78 and the sealing column 77 forward to ensure sufficient water supply and greatly improve the reliability of the device.

[0040] Example 3

[0041] A fixed cylinder 5 is fixedly installed on the inner wall of the air intake pipe 3. A spiral strip 6 is fixedly connected inside the fixed cylinder 5. The support ring 72 is fixedly connected to the fixed column 71.

[0042] The fixed cylinder 5 and the spiral strip 6 work together to allow the flue gas entering the inner cavity of the air inlet pipe 3 to move along the spiral, so that the flue gas can be gathered in the annular area near the inner wall of the fixed cylinder 5. When the water discharge cylinder 73 rotates, it will drive the clean water thrown out by the drain pipe 711 to move towards the fixed cylinder 5. This design can increase the flue gas concentration and increase its contact area with the clean water.

[0043] Example 4

[0044] A connecting tube 79 is movably sleeved on the rear side of the inner wall of the water discharge tube 73. A sealing ring 710 is glued to the outer surface of the connecting tube 79. The sealing ring 710 is made of rubber block and is interference fit with the inner wall of the water discharge tube 73. The bottom end of the connecting pipe 44 is fixedly connected to the connecting tube 79.

[0045] The connecting cylinder 79 is movably sleeved on the rear side of the inner wall of the drain cylinder 73, and forms a seal with the inner wall of the drain cylinder 73 through the sealing ring 710. The connecting cylinder 79 is connected to the connecting pipe 44, thereby facilitating the replenishment of water into the inner cavity of the drain cylinder 73.

[0046] Example 5

[0047] The length of the fan blade 74 is less than the length of the water discharge cylinder 73, and the fan blade 74 is generally distributed at an angle on the outer surface of the water discharge cylinder 73.

[0048] The inclined design of the fan blade 74 enables it to rotate mechanically under the action of flue gas, and drive the water discharge cylinder 73 and the drain pipe 711 to rotate, so that the clean water sprayed from the drain pipe 711 can act on the entire area of ​​the inner cavity of the air intake pipe 3, rather than a fixed area.

[0049] Example 6

[0050] A sealing cylinder 75 is fixedly installed on the front side of the inner wall of the water discharge cylinder 73. A spring 76 and a sealing column 77 are movably connected inside the sealing cylinder 75. The sealing column 77 is elastically supported on the inner wall of the sealing cylinder 75 by the spring 76. A sealing block 78 is glued to the rear end of the sealing column 77. The sealing block 78 abuts against the connecting cylinder 79.

[0051] This device utilizes a sealing cylinder 75, a spring 76, and a sealing column 77 located within the inner cavity of the water discharge cylinder 73 to achieve semi-automatic opening and closing of the water supply mechanism 4. The sealing column 77 is elastically supported on the inner wall of the sealing cylinder 75 by the spring 76, and drives the sealing block 78 to abut against the opening of the connecting cylinder 79. This design can prevent the replenished water from the connecting pipe 44 from flowing downwards without restriction. Then, a set of rings is provided on the outer side of the rear end of the sealing column 77. The rings are fixedly installed on the inner wall of the water discharge cylinder 73, so that the sealing column 77 and the sealing block 78 act as pistons. When the drain pipe 711 is subjected to the action of flue gas and generates negative pressure, the sealing column 77 drives the sealing block 78 to move forward relative to the rings and gradually move away from the rings. Then, a negative pressure is formed in the connecting pipe 44 and the connecting cylinder 79, thereby absorbing the replenished water in the water tank 41.

[0052] Example 7

[0053] Both the connecting cylinder 79 and the sealing column 77 have a "T" shaped axial section. The connecting cylinder 79 is hollow, and the sealing block 78 is made of rubber.

[0054] Both the "T"-shaped sealing column 77 and the connecting cylinder 79 have the function of connecting water flow. The connecting cylinder 79 is fixed and remains relatively stationary when the drain cylinder 73 rotates, ensuring that the supplementary water flowing downward from the connecting pipe 44 and the water tank 41 can enter the drain cylinder 73. The sealing column 77 moves forward under water pressure and opens the front opening of the connecting cylinder 79 to maintain water supply.

[0055] Example 8

[0056] When the device is working, the wooden plug 43 is pushed upward by the telescopic rod 42, which opens the water inlet 45;

[0057] After the water inlet 45 is opened, the inner cavity of the water tank 41 achieves air pressure balance. The water flowing downward through the connecting pipe 44 can reduce the energy consumption of the water flow through the siphon effect.

[0058] Example 9

[0059] There are four drain pipes 711 in each group, and the four drain pipes 711 are linearly and equidistantly distributed along the axis of the water discharge cylinder 73.

[0060] The opening of the drain pipe 711 is opposite to the direction of flue gas flow, thus preventing flue gas from entering it, and a negative pressure is formed inside the drain pipe 711, which can provide the power for the subsequent replenishment of water flow to the device.

[0061] Working principle:

[0062] When the device is working, the air inlet of the air inlet pipe 3 is connected to industrial flue gas with a high temperature of 200℃-300℃. Under normal flow conditions, the flue gas enters the device through the air inlet pipe 3 along the tangent of the cyclone separator 1 and forms a downward spiral airflow on the inner wall of the cyclone separator 1. At this time, the dust and other solid particles in the flue gas approach the inner wall of the cyclone separator 1 under the action of centrifugal force and undergo gravity settling during the downward spiral motion. The dust is discharged downward, while the purified flue gas rises through the exhaust pipe 2, activates the telescopic rod 42 and drives the wooden plug 43 to move upward, so that the water inlet 45 is opened.

[0063] Then, as Figure 7 As shown, the flue gas enters the interior of the intake pipe 3 and pushes the fan blade 74, causing the fan blade 74 to rotate the water discharge cylinder 73. When the flue gas passes through the opening end of the dispersion block 712 at high speed, due to the opposing design of the two, an outward negative pressure is generated near the dispersion block 712, which drives the sealing column 77 and the sealing block 78 to move forward. The opening of the connecting cylinder 79 is exposed, and the negative pressure begins to act on the replenishing water in the inner cavity of the water tank 41 through the connecting pipe 44. The water flows along the connecting pipe 44 into the inner cavity of the water discharge cylinder 73. And because the bottom opening of the connecting pipe 44 is lower than its top opening, the entire... The system generates a siphon effect, so the replenishing water flowing into the drain cylinder 73 does not consume additional negative pressure, and the water pressure generated by the downward flowing replenishing water will push the sealing block 78 and sealing column 77 forward and compress the spring 76. The replenishing water enters the interior of the drain pipe 711 and is fully dispersed under the interception of the dispersing block 712, thus entering the inner cavity of the air inlet pipe 3. It is heated by the high temperature flue gas and quickly evaporates into water vapor mixed with water. During this process, small solid particles in the flue gas are adsorbed by water vapor, thus forming large solid particles.

[0064] Finally, the flue gas entering the air intake pipe 3 is guided to form a spiral airflow when passing between the spiral strip 6 and the fixed cylinder 5, and the water discharge cylinder 73 is also rotated synchronously, thereby achieving all-round coverage of the flue gas in the inner cavity of the air intake pipe 3. When the flue gas stops being input, the telescopic rod 42 is activated and the wooden plug 43 is driven to reset downwards, closing the water inlet 45. At this time, due to the siphon effect, the downward flow of water power decreases, and the spring 76 drives the sealing column 77 and the sealing block 78 to reset, and re-seal the opening of the connecting cylinder 79.
