Description

Technical Field

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

[0002] Industrial flue gas refers to the general term for various pollutant gases discharged into the air during the combustion of fuel and production processes in the factory area of ​​the enterprise. These waste gases include carbon dioxide, carbon disulfide, carbon monoxide, smoke and production dust. Direct discharge will cause great pollution to the environment. Therefore, it is necessary to use environmental protection treatment and separation equipment to pre-treat the industrial flue gas, that is, to separate solid particles such as dust in the industrial flue gas. The more common and low-cost method is the cyclone separator. The industrial flue gas enters the separator tangentially along the separator inlet pipe and is re-separated by spiral downward movement. The gravity of some small dust solid particles is not high enough, and they are prone to form a reaction force of floating upward, thereby generating 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 single volume and mass of dust solid particles in the flue gas to overcome the above-mentioned potential defects.

[0005] 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, a water filling port is opened on the top of the water tank, the telescopic end of the telescopic rod is fixedly connected with a wooden plug, the bottom of the wooden plug is adapted to be clamped on the inner wall of the water filling port and forms a seal with the water filling port.

[0006] Furthermore, a fixing cylinder is fixedly installed on the inner wall of the air intake pipe, a spiral strip is fixedly connected inside the fixing cylinder, and the support ring is fixedly connected to the fixing column.

[0007] Furthermore, a connecting tube is movably sleeved on the rear side of the inner wall of the drain tube, a sealing ring is glued to the outer surface of the connecting tube, the sealing ring is made of a rubber block and has an interference fit with the inner wall of the drain tube, and the bottom end of the connecting tube is fixedly connected to the connecting tube.

[0008] Furthermore, the length of the fan blade is smaller than the length of the water discharge cylinder, and the fan blade is distributed obliquely on the outer surface of the water discharge cylinder as a whole.

[0009] Furthermore, a sealing cylinder is fixedly installed on the front side of the inner wall of the drain cylinder, and a spring and a sealing column are movably sleeved inside the sealing cylinder. The sealing column is elastically supported on the inner wall of the sealing cylinder by the spring, and a sealing block is glued to the rear end of the sealing column, which abuts against the connecting cylinder.

[0010] Furthermore, the axial cross-section shapes of the connecting tube and the sealing column are both "T"-shaped, the connecting tube is hollow in design, and the sealing block is made of a rubber block.

[0011] Furthermore, when the device is working, the wooden plug is pushed upward by the telescopic rod to open the water supply port.

[0012] Furthermore, there are four drain pipes in each group, and the four drain pipes are linearly and equidistantly distributed along the axis of the drain cylinder.

[0013] The present application provides an industrial flue gas environmental protection treatment and separation device, which has the following effects: 1. This device has redesigned the interior of the air inlet pipe and introduced the concept of water vapor gathering solid particles. This is mainly achieved by setting a water discharge cylinder inside the air inlet pipe, which is the only way for flue gas to pass through. A plurality of drainage pipes are installed on the outer surface of the water discharge cylinder. A connecting cylinder movably sleeved on the rear side of the inner wall of the water discharge cylinder is used to connect the water discharge cylinder with the inner cavity of the water tank, and continuously provide the water supply to the water discharge cylinder. When working, the flue gas flowing through the opening of the drainage pipe forms a negative pressure on the inner walls of the water discharge cylinder, the connecting pipe and the water tank, thereby sucking the supplementary water out of the drainage pipe. Through high-temperature heating, water vapor that captures solid dust particles is formed in the inner cavity of the air inlet pipe. In this process, small-volume solid particles in the flue gas are adsorbed by water vapor to form large-volume solid particles, thereby greatly improving the gravity sedimentation efficiency of dust in the flue gas inside the cyclone separator, and significantly improving the dust collection and separation efficiency of the device.

[0014] 2. The device also sets a water supply mechanism at the top of the air inlet pipe, and uses a connecting pipe to connect the water tank and the inner cavity of the drain cylinder, which are connected through the connecting cylinder, and clean water is continuously added to the inside of the drain cylinder. Through the inclined design of the drain pipe, when the smoke passes through its opening, negative pressure is formed in the inner cavity of the drain pipe and the drain cylinder, and the sealing column and the sealing block are driven backward, the connecting cylinder is opened, and the supplementary water in the water tank is sucked into the inner cavity of the drain cylinder through the generated negative pressure. At this time, the height difference between the upper and lower ends of the connecting pipe forms 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 the sealing column forward to ensure sufficient water supply, which greatly improves the reliability of the device.

[0015] 3. This device utilizes a sealing cylinder, a spring and a sealing column located in the inner cavity of the drain cylinder to realize the semi-automatic opening and closing of the water supply mechanism to replenish water. The sealing column is elastically supported on the inner wall of the sealing cylinder by a spring, and drives the sealing block to abut against the opening of the connecting cylinder. This design can prevent the replenishing water from the connecting pipe from flowing downward without restriction. Then, a group of rings are arranged on the outer side of the rear end of the sealing column. The rings are fixedly installed on the inner wall of the drain cylinder, so that the sealing column and the sealing block assume the function of a piston. When the drain pipe is subjected to the action of smoke to generate negative pressure, the sealing column drives the sealing block to move forward relative to the ring and gradually leaves the ring, and then forms negative pressure in the connecting pipe and the connecting cylinder, thereby absorbing the replenishing water in the water tank.

Example 1

[0020] See also Figure 1-Figure 9 The present invention discloses an environmentally friendly treatment and separation device for industrial flue gas, comprising a cyclone separator 1, an exhaust pipe 2 is installed on the top of the cyclone separator 1, an air intake pipe 3 is installed on the outer surface of the cyclone separator 1, and the interior of the air intake pipe 3 is installed with: The water supply mechanism 4 includes a water tank 41 fixedly mounted on the top of the air inlet pipe 3 and a connecting pipe 44, 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; The water discharge mechanism 7 includes two groups of fixed columns 71 and a support ring 72 fixedly mounted on the inner wall of the air inlet pipe 3. A water discharge cylinder 73 is rotatably mounted inside the support ring 72. The water discharge cylinder 73 is connected to the connecting pipe 44. The left and right sides of the outer surface of the water discharge cylinder 73 are fixedly connected to multiple groups of drainage pipes 711. The open end of the drainage pipe 711 is fixedly connected to a dispersion block 712. The outlet end of the drainage pipe 711 faces away from the air inlet direction of the air inlet of the air inlet pipe 3. Two groups of fan blades 74 are fixedly mounted equidistantly on the upper and lower sides of the outer surface of the water discharge cylinder 73. The present device has redesigned the interior of the air intake pipe 3, and introduced the concept of water vapor gathering solid particles, mainly by setting a water discharge cylinder 73 inside the air intake pipe 3, which is the only way for the flue gas to pass, and installing multiple sets of drainage pipes 711 on the outer surface of the water discharge cylinder 73, and using a connecting cylinder 79 movably sleeved on the rear side of the inner wall of the water discharge cylinder 73 to connect the water discharge cylinder 73 with the inner cavity of the water tank 41, and provide the water discharge cylinder 73 with continuous replenishment water. When working, the flue gas flowing through the opening of the drainage pipe 711 forms a negative pressure on the inner walls of the water discharge cylinder 73, the connecting pipe 44 and the water tank 41, so that the replenishment water is sucked out of the drainage pipe 711, and through high-temperature heating, water vapor is formed in the inner cavity of the air intake pipe 3 to capture solid dust particles.

[0021] The water supply mechanism 4 further includes a telescopic rod 42 fixedly mounted on the top of the air inlet pipe 3, the telescopic rod 42 is located in front of the water tank 41, a water supply port 45 is provided 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 clamped on the inner wall of the water supply port 45, and forms a seal with the water supply port 45; The device also sets the water supply mechanism 4 at the top of the air inlet pipe 3, and uses the connecting pipe 44 to connect the water tank 41 and the inner cavity of the drain cylinder 73, which are connected through the connecting cylinder 79, and the inside of the drain cylinder 73 is continuously supplemented with clean water. Through the inclined design of the drain pipe 711, when the smoke passes through its opening, a negative pressure is formed in the inner cavity of the drain pipe 711 and the drain cylinder 73, and the sealing column 77 and the sealing block 78 are driven backward to open the connecting cylinder 79. The supplementary water in the water tank 41 is sucked into the inner cavity of the drain cylinder 73 through the generated negative pressure. 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, thereby greatly improving the reliability of the device. Example 3

[0022] A fixing cylinder 5 is fixedly mounted on the inner wall of the air inlet pipe 3, a spiral strip 6 is fixedly connected inside the fixing cylinder 5, and a support ring 72 is fixedly connected to a fixing column 71; The fixed cylinder 5 and the spiral strip 6 cooperate to enable the smoke entering the inner cavity of the air inlet pipe 3 to move in a spiral direction, so that the smoke can gather in the circular area close to the inner wall of the fixed cylinder 5. When the drain cylinder 73 rotates, it will drive the clean water thrown out by the drain pipe 711 to move toward the fixed cylinder 5. This design can increase the smoke concentration and increase its contact area with the clean water. Example 4

[0023] A connecting tube 79 is movably sleeved on the rear side of the inner wall of the drain tube 73. A sealing ring 710 is glued to the outer surface of the connecting tube 79. The sealing ring 710 is made of a rubber block and has an interference fit with the inner wall of the drain tube 73. The bottom end of the connecting pipe 44 is fixedly connected to the connecting tube 79. The connecting tube 79 is movably sleeved on the rear side of the inner wall of the drain tube 73 and forms a seal with the inner wall of the drain tube 73 through the sealing ring 710. The connecting tube 79 is connected to the connecting pipe 44, so as to facilitate the replenishment of water into the inner cavity of the drain tube 73. Example 5

[0024] The length of the fan blade 74 is smaller than the length of the water discharge cylinder 73, and the fan blade 74 is distributed obliquely on the outer surface of the water discharge cylinder 73 as a whole; The inclined design of the fan blade 74 enables it to produce mechanical rotation under the action of smoke, and drives the drain tube 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 inlet pipe 3, rather than a fixed area. Example 6

[0025] A sealing cylinder 75 is fixedly installed on the front side of the inner wall of the drain cylinder 73. A spring 76 and a sealing column 77 are movably sleeved 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. The device utilizes a sealing cylinder 75, a spring 76 and a sealing column 77 located in the inner cavity of the drain cylinder 73 to realize the semi-automatic opening and closing of the water supply mechanism 4 for replenishing water. 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 replenishing water from the connecting pipe 44 from flowing downward without restriction. Then, a group of circular rings are arranged on the outer side of the rear end of the sealing column 77, and the circular rings are fixedly mounted on the inner wall of the drain cylinder 73, so that the sealing column 77 and the sealing block 78 assume the function of a piston. When the drain pipe 711 is subjected to the action of smoke and generates negative pressure, the sealing column 77 drives the sealing block 78 to move forward relative to the circular ring and gradually leaves the circular ring, and then forms negative pressure in the connecting pipe 44 and the connecting cylinder 79, thereby absorbing the replenishing water in the water tank 41. Example 7

[0026] The axial cross-sections of the connecting tube 79 and the sealing column 77 are both "T" shaped, the connecting tube 79 is hollow, and the sealing block 78 is made of a rubber block; The "T"-shaped sealing column 77 and connecting cylinder 79 both have the function of connecting water flow. The connecting cylinder 79 is fixed. When the drain cylinder 73 rotates, it is relatively still and ensures 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 the action of water pressure and opens the front end opening of the connecting cylinder 79 to maintain the water supply. Example 8

[0027] When the device is working, the wooden plug 43 is pushed upward by the telescopic rod 42, so that the water supply port 45 is opened; After the water replenishment port 45 is opened, the air pressure balance is formed in the inner cavity of the water tank 41, and the water flowing downward through the connecting pipe 44 can reduce the energy consumption of the water flow through the siphon effect. Embodiment 9

[0028] Each group of drainage pipes 711 has four drainage pipes 711, and the four drainage pipes 711 are linearly and equidistantly distributed along the axis of the water discharge cylinder 73; The opening of the drain pipe 711 is opposite to the flow direction of smoke, thereby preventing smoke from entering therein, and forming a negative pressure inside the drain pipe 711, which can provide power for subsequent water flow to be supplemented to the device.

[0029] Working principle: When the device is working, the air inlet of the air inlet pipe 3 is connected to the high-temperature industrial flue gas of 200℃-300℃. Under normal process, the flue gas enters the device along the tangent of the cyclone separator 1 through the air inlet pipe 3, and forms a spiral airflow moving downward on the inner wall of the cyclone separator 1. At this time, solid particles such as dust in the flue gas approach the inner wall of the cyclone separator 1 under the action of centrifugal force, and settle by gravity during the downward spiral movement. The dust is discharged downward, and the purified flue gas passes upward through the exhaust pipe 2, starts the telescopic rod 42 and drives the wooden plug 43 to move upward, so that the water supply port 45 is opened; Then, if Figure 7As shown, the smoke enters the interior of the air inlet pipe 3 backward along the arrow (the direction of the arrow is the direction of movement of the smoke) and pushes the fan blade 74, so that the fan blade 74 drives the drain cylinder 73 to rotate. When the smoke passes through the open end of the dispersion block 712 at a high speed, since the two are designed to be opposite to each other, an outward negative pressure is generated near the dispersion block 712, and the sealing column 77 and the sealing block 78 are driven to move forward, and the opening of the connecting cylinder 79 is exposed. The negative pressure begins to act on the supplementary water in the inner cavity of the water tank 41 through the connecting pipe 44, and the water flows along the connecting pipe 44 into the inner cavity of the drain cylinder 73, and since the bottom end opening of the connecting pipe 44 is low The top opening of the drain pipe 711 generates a siphon effect in the whole system. Therefore, the supplementary water flowing into the drain tube 73 does not consume additional negative pressure, and the water pressure generated by the supplementary water flowing downward also pushes the sealing block 78 and the sealing column 77 forward and compresses the spring 76. The supplementary water enters the drain pipe 711 and is fully dispersed under the interception of the dispersion block 712, thereby entering the inner cavity of the intake pipe 3, and is heated by the high-temperature flue gas and quickly evaporated into water vapor mixed with water and liquid. In this process, small-volume solid particles in the flue gas are adsorbed by the water vapor, thereby forming large-volume solid particles. Finally, the smoke 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 driven to rotate synchronously, thereby achieving all-round coverage of the smoke in the inner cavity of the air intake pipe 3. When the smoke stops entering, the telescopic rod 42 is started and the wooden plug 43 is driven to reset downward to close the water supply port 45. At this time, the power of the water flowing downward due to the siphon effect 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.
