Description

Technical Field

[0001] The present invention relates to the technical field of dust removal devices, and particularly to a high-gravity dust removal device. Background Art

[0002] In the technical field of environmental protection equipment, especially in the treatment of dust under high-temperature, high-humidity, high-viscosity, flammable and explosive working conditions, traditional dust removal equipment such as bag filters has problems such as low efficiency, high energy consumption, and frequent filter material replacement, and it is difficult to meet the requirements of modern industry for efficient, stable and economical dust removal solutions. In a high-temperature environment, the filter bags of traditional bag filters are easily damaged, and in the case of high-viscosity dust working conditions, dust agglomerates on the surface of the filter bags, resulting in an increase in filtration resistance, a decrease in dust removal efficiency, and frequent filter bag replacement, increasing the operating cost and maintenance workload.

[0003] As a new dust removal method, high-gravity dust removal technology simulates the enhanced effect of the earth's gravity field and uses the centrifugal force generated by rotation to separate dust particles in the air flow, with advantages such as high separation efficiency and small equipment volume. However, there are still some deficiencies in the existing high-gravity dust removal technology. For example, high-viscosity dust is likely to accumulate inside the equipment, causing blockage and affecting the continuous operation of the equipment. Summary of the Invention

The electric ash discharging valve is arranged on the bottom wall of the ash collecting hopper, and dust can accumulate on the valve of the electric ash discharging valve. The dust conveying pipe is communicated through the electric ash discharging valve.

[0014] In one embodiment, the ash collecting hopper is arranged directly below the supergravity rotor. The spraying module further includes a liquid collecting tank.

The auxiliary ash discharge module can make the pressurized nitrogen gas flow impact the ash discharge port, breaking or vibrating the agglomerated high-humidity dust in or near the exhaust port, improving the continuity of dust discharge, and filling the gas in and near the dust discharge port with nitrogen.

[0036] The present invention provides a high-gravity dust removal device.

[0037] Please refer to Figure 1 , in an embodiment of the present invention, the high-gravity dust removal device includes:

[0038] A cavity 100, including an air inlet 11 provided on the side wall of the cavity 100 and facing the tangential direction of the side wall of the cavity 100, an exhaust port 12 provided on the top wall of the cavity 100, and a dust discharge port 13 provided on the bottom wall of the cavity 100;

[0039] An air inlet module, which is provided at the air inlet 11 and is used to introduce the dust-containing gas and regulate the flow direction and speed of the dust-containing gas through a rotating vane group;

[0040] An electrostatic dust removal module 200, including a high-gravity rotor 21 provided in the middle of the cavity 100. A packing layer 211 is provided inside the high-gravity rotor 21, and static electrodes 212 are provided in the packing layer 211. The static electrodes 212 generate an electrostatic field to charge the dust particles so that the dust particles are adsorbed on the packing layer 211. The high-gravity rotor 21 rotates at a high speed to throw the uncharged dust particles in the dust-containing gas towards the outer wall of the rotor, and gas-solid separation is achieved under the synergistic action of the electric field force and the centrifugal force;

[0041] A spray module 300, which is provided on the inner wall of the cavity 100 and installed above the high-gravity rotor 21, and is used to spray an atomized water curtain to moisten and adhere to the dust particles and clean the inside of the high-gravity rotor 21 at the same time;

[0042] An auxiliary ash discharge module 400, which is provided at the dust discharge port 13 and includes a pulse-type nitrogen pressurizing device for preventing high-humidity dust from caking and improving the continuity of ash discharge.

[0043] In the technical solution of the present invention, the dusty gas forms a swirling flow field through the tangential air inlet method. Coarser dust particles can be pre-separated under the action of centrifugal force, reducing the load of subsequent electrostatic dust removal. The rotating guide vane group can adjust the rotation direction and rotation speed of the blades to adapt to dusty gases with different dust concentrations. The centrifugal force brought by the high-speed rotation of the high-gravity rotor 21 and the electrostatic field brought by the static electrode plate 212 can cooperate synergistically. The centrifugal force is used to separate larger dust particles, and the electrostatic field is used to adsorb smaller dust particles, improving the dust removal effect on the dusty gas. The spraying module 300 sprays atomized droplets onto the high-gravity rotor 21, increasing the moisture content of the dust adhering to the high-gravity rotor 21, improving the adhesion performance of the dust, preventing the secondary dust emission, and at the same time, the high-gravity rotor 21 can be cleaned by increasing the amount of water sprayed. The auxiliary dust discharge module 400 can make the pressurized nitrogen gas flow impact the dust discharge port, shattering or vibrating the caked high-humidity dust inside or near the exhaust port 12, improving the continuity of dust discharge, and filling the gas inside and near the dust discharge port 13 with nitrogen. Due to the inertness of nitrogen, the hazard of dust explosion is reduced.

[0044] In one embodiment, the auxiliary dust discharge module 400 includes an ash collection hopper 41. The ash collection hopper 41 is provided on the bottom wall of the cavity 100, communicates with the dust discharge port 13, and is located directly below the high-gravity rotor 21. The spraying module 300 further includes a liquid collection tank 31. The liquid collection tank 31 surrounds the bottom wall of the cavity 100. A superhydrophobic coating is provided on the inner wall of the ash collection hopper 41, and a hydrophilic coating is provided on the inner wall of the liquid collection tank 31. The spraying liquid is sprayed from the spraying module 300 onto the high-gravity rotor 21 and combines with the dust on the high-gravity rotor 21 to form a dust-containing liquid film. The dust-containing liquid film converges into dust-containing liquid droplets and is thrown onto the inner wall of the cavity 100 under the action of centrifugal force. The dust-containing liquid droplets slide into the liquid collection tank 31 on the inner wall of the cavity 100. The hydrophilic coating applied on the liquid collection tank 31 enables more dust-containing liquid droplets to smoothly flow into the liquid collection tank 31. The ash collection hopper 41 is used to collect larger particles thrown out by the centrifugal force, and the superhydrophobic coating applied on the inner wall of the ash collection hopper 41 helps to prevent the dust-containing liquid droplets on the bottom wall of the cavity 100 from sliding into the ash collection hopper 41, reducing the liquid content entering the dust collection hopper and the probability of dust caking in the dust collection hopper. Among them, the auxiliary dust discharge module 400 can shatter the high-humidity dust blocks formed after some dust-containing liquid droplets are thrown into the ash collection hopper 41, making the dust discharge port 13 smooth. In other embodiments, it may also be that no superhydrophobic coating is provided on the inner wall of the ash collection hopper 41, and no hydrophilic coating is provided on the inner wall of the liquid collection tank 31.

[0045] In one embodiment, the auxiliary ash discharge module 400 further includes a level gauge 42, an electric ash discharge valve 43, and a dust conveying pipe 44 provided in the ash hopper 41. The level gauge 42 monitors the dust level in the ash hopper 41 in real time. The electric ash discharge valve 43 is provided on the bottom wall of the ash hopper 41, and dust can accumulate on the valve of the electric ash discharge valve 43. The dust conveying pipe 44 is connected through the electric ash discharge valve 43. When the dust content in the ash hopper 41 reaches a preset amount, the electric ash discharge valve 43 is activated to allow the dust in the dust collection hopper to enter the dust conveying pipe 44. After the dust that can be normally discharged is successfully discharged, or when the dust discharge is blocked, the nitrogen pressurizing device cleans the caked dust in the ash hopper 41. In other embodiments, the level gauge 42 may not be provided, and the ash hopper 41 is cleaned after a preset time interval.

[0046] In one embodiment, the nitrogen pressurizing device includes a nitrogen cylinder, a pressurizing device, a pulse control valve, and a jetting system connected in sequence. The jetting system includes a plurality of nitrogen nozzles 45. The plurality of nitrogen nozzles 45 are arranged in a ring at the bottom of the ash hopper 41, and the nitrogen nozzles 45 are arranged to face the middle or top of the ash hopper 41. In addition to directly impacting the dust caking, the nitrogen nozzles 45 can also, through the pulse control valve, jet nitrogen towards the side wall of the ash hopper 41 at a preset pulse frequency to cause high-frequency vibration of the wall of the ash hopper 41, so as to vibrate the caked dust away from the wall of the ash hopper 41. In other embodiments, the pulse control valve may not be provided, and the nitrogen pressurizing device further includes a movable seat for rotating the nitrogen nozzles 45.

[0047] In one embodiment, a plurality of corrugated meshes 213 are provided in the packing layer 211. The corrugated meshes 213 are made of stainless steel. At least one corrugated mesh 213 is provided on opposite sides of the static electrode plate 212, and the corrugated mesh 213 is grounded. The corrugated mesh 213 cooperates with the static electrode plate 212 to serve as the grounding electrode of the static electrode plate 212. Dust particles with charges in the electrostatic field move towards the corrugated mesh 213 and adhere to the corrugated mesh 213. The pores on the corrugated mesh 213 can enable the spray liquid to form a liquid film, so that after combining with the dust particles to form a dust-containing liquid film, it is thrown off the corrugated mesh 213. Further, the packing layer 211 further includes an insulating support, and the insulating support is arranged between the corrugated mesh 213 and the static electrode plate 212, so that there is a gap between the corrugated mesh 213 and the static electrode plate 212. The material of the insulating support is configured as ceramic or polytetrafluoroethylene. Further, a plurality of static electrode plates 212 are provided and arranged at intervals in the radial direction of the high-gravity rotor 21, so that an alternating structure of "corrugated mesh 213 - static electrode plate 212 - corrugated mesh 213" is formed in the packing layer 211. Further, conductive coatings and catalytic coatings are provided on the surfaces of the corrugated mesh 213 and the static electrode plate 212. The conductive coatings improve the conductivity of the surfaces of the corrugated mesh 213 and the static electrode plate 212, and the highly conductive surfaces can avoid local insulation caused by dust accumulation and maintain stable corona discharge of the static electrode plate 212. The catalytic coatings can degrade the harmful gases contained in the dust-containing gas. For example, when the catalyst in the catalytic coating is the MnO2-CeO2 catalyst glue, it can decompose VOCs and ozone. In other embodiments, it may also be that the surfaces of the corrugated mesh 213 and the static electrode plate 212 are not provided with conductive coatings and catalytic coatings.

[0048] In one embodiment, the static electrode plate 212 is configured as a corrugated plate structure. The concave and convex structure of the corrugated plate makes the electric field lines dense at the wave crests and dispersed at the wave troughs, forming a periodic non-uniform electric field and increasing the surface area of the static electrode plate 212 to be able to adsorb more dust particles. Among them, when the dust-containing gas flow scours the static electrode plate 212, the corrugated grooves guide the dust-containing gas flow to scour the wave crests (the area with the highest field strength), reducing the dust deposition at the wave crests. After the dust is washed off the wave crests, the charged dust particles are adsorbed at the wave troughs (the low-field-strength area) due to the mirror force, avoiding the secondary flying of the dust particles, so that the static electrode plate 212 can adsorb more dust. And when the static electrode plate 212 rotates following the high-gravity rotor 21, the corrugated plate forces the gas flow to form turbulence, prolonging the time for the dust to stay near the static electrode plate 212, increasing the number of charged dust, and improving the dust removal effect.

[0049] In one embodiment, the spraying module 300 includes a water pump 32, a water delivery pipe 33, and a spray head 34 that are connected in sequence. The spray head 34 is provided on the inner wall of the cavity 100. There are multiple spray heads 34, which are evenly distributed along a ring above the high-gravity rotor 21, so as to be able to evenly spray atomized spraying liquid onto the high-gravity rotor 21, making the spraying liquid on the high-gravity rotor 21 evenly covered. In other embodiments, the spray heads 34 may also be distributed along the axial direction of the high-gravity rotor 21.

[0050] In one embodiment, the structure of the cavity 100 is configured as a cylinder, and the structure of the high-gravity rotor 21 in the cavity 100 is configured as a sphere, and the diameter of the structure of the high-gravity rotor 21 in the cavity 100 can match the diameter of the cavity 100. That is, the static electrode plate 212 and the corrugated mesh 213 are arranged in a ring on the rotating shaft of the high-gravity rotor 21. At this time, when the high-gravity rotor 21 rotates at a high speed, dust particles will preferentially gather at the maximum diameter of the high-gravity rotor 21 and then be thrown out, increasing the probability of throwing the dry dust into the ash collection hopper 41. Further, the air inlet 11 is provided on the lower side of the high-gravity rotor 21. That is, the dust-containing gas cannot directly flow to the exhaust port 12 without bypassing the packing layer 211, increasing the dust removal efficiency.

[0051] In one embodiment, the spraying module 300 is further provided with a liquid collecting tank 31, a circulating water tank 35, and a filter 36. The liquid collecting tank 31 collects the spraying liquid thrown out by the high-gravity rotor 21. The liquid collecting tank 31 is communicated with the circulating water tank 35. The filter 36 is arranged between the liquid collecting tank 31 and the circulating water tank 35. The circulating water tank 35 is connected to the water delivery pipe 33 through the water pump 32. After the dust-containing liquid droplets are collected in the liquid collecting tank 31, they enter the circulating water tank 35 through the filtration of the filter 36 to save the utilization of water resources. Further, the spraying module 300 further includes an electrocoagulation assembly 37. The electrocoagulation assembly 37 is arranged between the liquid collecting tank 31 and the circulating water tank 35 and is communicated with the filter 36 to remove the charged dust colloid in the spraying liquid. In other embodiments, the electrocoagulation assembly may not be provided.

[0052] In one embodiment, the supergravity dust removal device further includes an intelligent control system, which includes a sensor group and an electric control component electrically connected to the sensor group. The sensor group includes a dust concentration sensor, a temperature sensor, a humidity sensor, and an electrostatic field strength sensor arranged near the supergravity rotor 21 in the cavity 100. The electric control component is electrically connected to the air intake module, the electrostatic dust removal module 200, the spray module 300, and the auxiliary dust removal module 400. The dust concentration sensor directly reflects the amount of dust that needs to be processed in the cavity 100. When the concentration is high, the electric control component needs to appropriately reduce the rotation speed of the rotating guide vane group, reduce the dust-containing gas entering the cavity 100, and at the same time increase the rotation speed and electrostatic field strength of the supergravity rotor 21 to enhance the dust processing capacity. However, it is necessary to pay attention to the situation that the pressure loss is too high or the energy consumption increases sharply. The temperature sensor detects the temperature in the cavity 100, because too high or too low temperature may affect the corona discharge effect. The electric control component can cool down by adjusting the spraying amount of the spray module 300, or adjust the electrostatic field voltage to compensate for temperature changes. Since high humidity may affect the conductivity of dust, resulting in a decrease in the effect of the electrostatic field, the spray system itself will increase humidity. The electronic control component needs to balance the spray volume and the electrostatic field parameters to prevent condensation or equipment corrosion caused by excessive humidity. When the humidity is too high, the electronic control component prevents the dust in the dust hopper from blocking the dust discharge port 13 by reducing the spray volume or increasing the dust discharge frequency. The electrostatic field strength sensor directly monitors the state of the electric field to ensure that it is in the optimal working range. If the electric field strength is insufficient, it may be necessary to increase the voltage or check whether there is too much dust accumulated on the static electrode plate 212. The electronic control component cleans it through the linkage spray module 300 to keep the electrode surface clean and maintain the electric field efficiency. The electronic control board can determine whether to open the pulse control valve for dust discharge based on the dust accumulation in the dust hopper by the level meter 42 and the data of the humidity sensor in the cavity 100.
