Description

Technical Field

[0001] The invention relates to the technical field of flue gas adsorption and purification, and in particular to an adsorption and purification device for harmful particles of polluted flue gas produced in industrial production. Background Art

[0002] The adsorption and purification of harmful particles in polluted flue gas in industrial production is an important environmental protection technology, which aims to remove harmful particle pollutants in flue gas and reduce the harm to the environment and human health. This technology usually adsorbs and purifies harmful particles by physical adsorption or chemical adsorption. The adsorption process can be carried out in specially designed adsorption equipment, such as fixed bed adsorber, moving bed adsorber or fluidized bed adsorber, etc. It can also be combined with other purification technologies, such as electrostatic dust removal, bag dust removal, etc., to improve the overall purification efficiency of polluted flue gas, achieve more thorough removal of harmful particles, and meet environmental emission standards; The existing adsorption purification equipment has poor effect of removing harmful particles by impact during inertial dust removal and is prone to clogging. During spray purification, the contact time between the flue gas and the treatment liquid is short. Therefore, we propose an adsorption purification equipment for harmful particles in polluted flue gas produced in industrial production. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides an industrial production polluted flue gas harmful particle adsorption and purification equipment, comprising: A sedimentation tank, wherein a support plate is fixedly connected to the top of the sedimentation tank, and the support plate is symmetrically arranged on the top of the sedimentation tank, and a drainage pipe is fixedly connected to the side of the sedimentation tank; An adsorption purification mechanism, wherein the adsorption purification mechanism is arranged on the top of the sedimentation tank, and the surface of the adsorption purification mechanism is fixedly connected to the side of the two support plates close to each other; Wherein, the adsorption purification mechanism comprises: A sedimentation cylinder, the inner side of which is fixedly connected with a sedimentation assembly; A first fixing ring is fixedly connected to the outer side surface of the sedimentation cylinder, and a surface of the first fixing ring is fixedly connected to the support plate; A spray barrel, the inner side of which is fixedly connected with a spray assembly; A second fixing ring is fixedly connected to the outer side surface of the spray cylinder, and a surface of the second fixing ring is fixedly connected to the support plate; A connecting pipe, both ends of which extend into the interior of the settling cylinder and the spray cylinder respectively, and both ends of the connecting pipe are fixedly connected to the inner side surfaces of the settling cylinder and the spray cylinder respectively; The polluted flue gas first enters the sedimentation cylinder from the bottom of the sedimentation cylinder, and then passes through the connecting pipe and the spray cylinder in turn, and finally leaves the purification equipment. When the polluted flue gas is inside the sedimentation cylinder, the sedimentation component deflects the polluted flue gas, and the large harmful particles in the polluted flue gas are settled by inertia. Then the polluted flue gas enters the spray cylinder, and the spray assembly sprays out the treatment liquid to adsorb the small harmful particles in the polluted waste gas and treat the industrial waste gas at the same time. The treatment sequence of inertial sedimentation first and then spraying can reduce the treatment load of the spray assembly and reduce the treatment difficulty. The sedimentation cylinder is partially located inside the sedimentation tank. The sedimentation tank can form a water seal at the bottom of the sedimentation cylinder to prevent gas leakage while dissolving the settled dust inside the sedimentation tank to avoid blockage. The spray wastewater also enters the sedimentation tank to complete the collection of wastewater.

[0004] Furthermore, the sedimentation assembly includes an air inlet pipe, which is arranged at the bottom of the sedimentation cylinder and at the center of the sedimentation cylinder. The end of the air inlet pipe away from the sedimentation cylinder is bent and extended to the outside of the sedimentation tank, and the outer side of the air inlet pipe is fixedly connected to the inner side of the sedimentation tank. The side of the sedimentation cylinder close to the sedimentation tank is fixedly connected with a cone, and the cone is sleeved on the outside of the air inlet pipe. The air inlet pipe is connected to the polluted flue gas, and the polluted flue gas enters the sedimentation cylinder, then settles inside the sedimentation cylinder, then falls into the cone, and finally sinks to the bottom of the sedimentation tank. The cone is partially submerged in the sedimentation tank to form a water seal to prevent leakage of polluted flue gas. At the same time, the conical design can gather harmful particles to prevent harmful particles from adhering to the inner wall of the cone. When the particles contact the liquid in the sedimentation tank, the binding force between the dust is reduced, and the wetting effect is cooperated to make the dust quickly dissolve in the liquid to prevent the cone from being blocked.

[0005] Furthermore, a settling plate is arranged inside the settling cylinder, and a plurality of the settling plates are evenly distributed along the circumference of the settling cylinder, and a first settling frame is slidably connected to a side of the settling plate away from the center of the settling cylinder, and a plurality of the first settling frames are evenly distributed along the circumference of the settling cylinder, and a second settling frame is slidably connected to a side of the first settling frame away from the settling plate, and a plurality of the second settling frames are evenly distributed along the circumference of the settling cylinder, and a side of the second settling frame away from the first settling frame is fixedly connected to an inner side surface of the settling cylinder, driving a plurality of settling plates and a plurality of first settling frames to perform differential rotation. When a plurality of settling plates and a plurality of first settling frames rotate differentially, When the gaps between them overlap, the polluted flue gas enters the first sedimentation frame through the gaps between the sedimentation plates. Similarly, the polluted flue gas enters the gaps between the second sedimentation frames through the gaps between the first sedimentation frames, then enters the sedimentation cylinder, and finally enters the inside of the connecting pipe, or returns to the sedimentation plate, the first sedimentation frame, and the second sedimentation frame from the side close to the cone cylinder. At the same time, when the first sedimentation frame rotates, it drives the gas to produce a vortex, and the harmful flue gas produces disordered deflections inside the sedimentation cylinder, causing the harmful particles to collide with the sedimentation plate, the first sedimentation frame, and the second sedimentation frame in a disordered manner. Under the action of inertia in different directions, the harmful particles are fully settled and finally fall into the inside of the cone cylinder.

[0006] Furthermore, a plurality of the settling plates are fixedly connected to a bent plate on one side close to the center of the settling cylinder, and the bent plates are bent toward the same side. The settling plates rotate, driving the bent plates to rotate, and the bent plates drive the harmful flue gas to generate a vortex, further improving the effect of removing harmful particles.

[0007] Furthermore, the sedimentation plate, the first sedimentation frame and the second sedimentation frame are all provided with circular grooves on one side close to the center of the sedimentation cylinder, and a plurality of the circular grooves are evenly distributed. The circular grooves can increase the roughness of the sedimentation plate, the first sedimentation frame and the second sedimentation frame, increase the impact area and angle of harmful particles, and improve the removal effect of harmful smoke.

[0008] Furthermore, a differential is fixedly connected to a side of the second sedimentation frame away from the sedimentation tank, and two output ends of the differential are respectively fixedly connected to the sedimentation plate and the side of the first sedimentation frame away from the sedimentation tank, the outer side of the differential is fixedly connected to a mounting ring, the inner side of the mounting ring is also fixedly connected to a motor, the end of the motor close to the differential is fixedly connected to a rotating shaft, and the output end of the motor is fixedly connected to the rotating shaft, the rotating shaft extends into the inside of the differential, the surface of the rotating shaft is rotationally connected to the inner side of the differential, and the rotating shaft is transmission-connected to the internal structure of the differential, the outer side surface of the mounting ring is fixedly connected to the first fixed ring, the motor is started, the output end of the motor drives the rotating shaft to rotate, the rotating shaft drives the differential to operate, the two output ends of the differential generate differential rotation, and finally drive the sedimentation plate and the first sedimentation frame to generate differential rotation.

[0009] Furthermore, the spray assembly includes a trough body, which is opened at one end of the spray tube close to the sedimentation tank, and a plurality of trough bodies are evenly distributed along the circumference of the sedimentation tank. One end of the spray tube with the trough body is fixedly connected to the bottom of the inner side of the sedimentation tank. The trough body is opened to connect the spray tube with the sedimentation tank, and the spray wastewater enters the sedimentation tank through the trough body. The volume of the sedimentation tank is much larger than that of the spray tube and the sedimentation tube. When the sedimentation tank is sprayed, the liquid level rises slowly and will not completely submerge the cone.

[0010] Furthermore, a spray head is provided on the side of the spray barrel away from the sedimentation tank. The spray head is arranged inside the spray barrel, and the outer side surface of the spray head is fixedly connected to the inner side surface of the spray barrel. The spray head is connected to the treatment liquid, and the treatment liquid is atomized through the spray head and then sprayed out to further treat harmful particles and exhaust gas.

[0011] Furthermore, a spray ring is arranged directly below the spray head, and the outer side surface of the spray ring is fixedly connected to the inner side surface of the spray cylinder, and the outer side surface of the spray ring is fixedly connected to the end of the connecting pipe away from the sedimentation cylinder, and the inner side surface of the spray ring is fixedly connected to a porous ring plate. Harmful flue gas enters the spray ring through the connecting pipe and is finally sprayed out through the small holes on the porous ring plate, so that the harmful flue gas contacts the treatment liquid at a vertical angle, thereby improving the removal effect of harmful particles.

[0012] Furthermore, a slow flow tube is arranged directly below the spray ring, and one end of the slow flow tube close to the spray ring is fixedly connected to the inner side surface of the spray tube, and a gap is left between the end of the slow flow tube away from the spray ring and the inner side surface of the spray tube. The slow flow tube is arranged in an hourglass shape, and an exhaust pipe is fixedly connected to a position on the outer side of the spray tube close to the depression of the slow flow tube. The spray sewage drips into the slow flow tube and then enters the sedimentation tank through the trough body. The exhaust gas passes through the inside of the slow flow tube and then passes through the gap between the bottom of the slow flow tube and the spray tube and finally leaves through the exhaust pipe to separate the exhaust gas and wastewater. The hourglass-shaped slow flow tube can delay the passage of sewage, thereby forming a water seal, so that the exhaust gas stays at the top of the hourglass shape longer, thereby increasing the contact time between the treatment liquid and the harmful particles, and obtaining a better treatment effect.

[0013] The present invention has the beneficial effects: 1. The present invention sets an adsorption purification mechanism, and the sedimentation component deflects the polluted flue gas, and the large harmful particles in the polluted flue gas are settled by inertia. The spray component sprays the treatment liquid to adsorb the small harmful particles in the polluted waste gas, and treats the industrial waste gas at the same time.

The sedimentation cylinder is partially located inside the sedimentation tank, and the sedimentation tank can form a water seal at the bottom of the sedimentation cylinder to avoid gas leakage, while dissolving the settled dust inside the sedimentation tank to avoid blockage.

[0014] 2. The present invention sets a cone, which is partially submerged in the sedimentation tank, to form a water seal to prevent the leakage of polluted flue gas. At the same time, the conical design can gather harmful particles to prevent them from adhering to the inner wall of the cone. When the particles contact the liquid in the sedimentation tank, the binding force between the dust is reduced, and the dust is quickly dissolved in the liquid with the wetting effect, thereby preventing the cone from being blocked.

When the gaps between the plurality of sedimentation plates and the plurality of first sedimentation frames overlap, the polluted flue gas passes through, or returns to the sedimentation plate, the first sedimentation frame and the second sedimentation frame from the side close to the cone again. When the first sedimentation frame rotates, it drives the gas to generate a vortex, and the harmful flue gas generates disordered deflections inside the sedimentation cylinder, causing the harmful particles to collide with the sedimentation plate, the first sedimentation frame and the second sedimentation frame in a disordered manner. Under the action of inertia in different directions, the harmful particles are fully settled.

[0016] 4. The present invention arranges a spray assembly and opens a trough body to connect the spray cylinder with the sedimentation tank. The spray wastewater enters the sedimentation tank through the trough body. The volume of the sedimentation tank is much larger than the spray cylinder and the sedimentation cylinder. When the sedimentation tank is sprayed, the liquid level rises slowly and will not completely submerge the cone. The flue gas is sprayed out through the small holes on the porous ring plate, so that the harmful flue gas contacts the treatment liquid at a vertical angle, thereby improving the removal effect of harmful particles.

[0017] 5. The present invention provides a slow flow tube in the shape of an hourglass, which can delay the passage of sewage, thereby forming a water seal, so that the exhaust gas stays at the top of the hourglass shape longer, increasing the contact time between the treatment liquid and the harmful particles, and obtaining a better treatment effect.
