Description

Self-cleaning rotational flow electromagnetic purification cylinder

Technical Field

The utility model relates to an exhaust emission's purifier especially relates to an automatic operation, be favorable to retrieving the self-cleaning whirl electromagnetic purification section of thick bamboo of recycling magnetism dust in the waste gas.

Background

The existing exhaust gas purification treatment scheme aiming at pollutants containing magnetic particles mainly comprises the following steps: electrostatic precipitation mode and interference filtration mode (i.e. physical filtration of particles by a filter screen). But the metal particles or the magnetic particles with recovery value can not be efficiently purified, recovered and reused.

From the aspect of electrostatic dust removal, the working principle of the electrostatic dust removal device is that smoke dust of smoke is positively charged when the smoke passes through a flue in front of a main structure of the electric dust remover, and then the smoke enters an electric dust remover channel provided with a plurality of layers of cathode plates. The positive charge smoke dust and the negative plate are mutually adsorbed, so that the particle smoke dust in the smoke gas is adsorbed on the negative plate. Then the negative plate is struck at regular time, so that the smoke dust with certain thickness falls down in an ash hopper below the electric dust collector structure under the dual functions of self weight and vibration, and the aim of removing the smoke dust in the smoke gas is fulfilled. However, the treatment mode is not suitable for treating and intercepting metal dust, and after the metal dust is attached to the interior of the electric dust removal device, short circuit in the equipment is easily caused, the equipment is damaged, and great potential safety hazards exist.

From the perspective of dry filtration: the filter screen is used for filtering particle pollutants in air, is usually made of chemical fibers or glass fibers, and is mainly used for removing particles with the particle size of more than 0.5 micrometer through a microscopic flocculent structure and intercepting tiny dust contained in the air passing through the filter screen. However, when the method is applied to magnetic metals such as iron, cobalt, nickel and the like or magnetic dust, due to the structural characteristics of the filter screen, only the dust particles are fixed by the flocculent structure of the filter screen, so that the possibility of recycling is lost, and the waste of related materials is caused.

The exhaust gas purification treatment schemes are objectively understood, the dust collecting parts need to be cleaned or the filter screens need to be replaced manually, and the material consumption and the labor cost are high. It is necessary to intercept and recycle metal dust (iron-cobalt-nickel magnetic metal or its oxide) or magnetic dust, and to improve the service life of the post-purification section.

Detailed Description

The following detailed description is made of specific embodiments of the present invention with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and grasp, and thus make a clearer definition of the protection scope of the present invention.

In view of the obvious defects of the traditional clearing mode of magnetic particles in the existing factory waste flue gas treatment, and the realization of recycling of the materials, the designer actively researches and innovates to provide a self-cleaning rotational flow electromagnetic purification cylinder, and the improvement of the equipment structure combining multiple physical principles can realize the waste flue gas treatment with automation, low material consumption, labor and energy consumption cost.

From the assembly and positioning of the purification cylinder of the innovation, the purification cylinder is mainly connected in a pipeline between a factory waste gas exhaust pipe 1 and a high-altitude exhaust outlet. Specifically, as shown in fig. 1, the pipeline in front of the high-altitude exhaust outlet further includes an exhaust tower 4 extending vertically upward, an exhaust fan at the bottom of the tower, an auxiliary dust-removing purification box 3 in front of the exhaust fan, a drop air pipe 2 adapted in height, and the like. The purifying cylinder 5 is arranged at the front section of the waste flue gas treatment close to the waste gas exhaust pipe of the factory building, and aims to reduce the configuration requirement of an auxiliary dust removal purifying box at the rear section and prolong the service life. The cylinder 51 is positioned on the mounting bracket 8 and suspended from the ground, and the top of the cylinder is in butt joint communication with the drop air pipe 2.

The purifying cylinder 5 needs to be combined with the external devices such as a waste liquid sedimentation tank 6 and a cleaning machine 7 to realize the required functions, and has the structural characteristics as outlined in fig. 2, including a vertically through cylinder body 51, wherein the bottom of the cylinder body 51 is provided with an air inlet 52 which is butted with a factory waste gas exhaust pipe, and the top of the cylinder body is provided with an air outlet 53; in particular, the cylinder 51 is provided with guide fins 54 for guiding the exhaust gas to spirally flow upwards, the inner wall of the cylinder is densely distributed with magnetic conductive dust collecting fins 55, and the outer wall of the cylinder is provided with an electromagnet 56; the top of the cylinder is connected with a cleaning main pipe 72 which penetrates through the exhaust port and is externally connected with the cleaning machine 7, the cleaning main pipe 72 is connected with more than two cantilever pipes 74 at the axial top of the cylinder through a rotary sealing joint 73, the cantilever pipes 74 extend into the gap between the radial profiles of the dust collecting fins 55 and the guide fins 54, and the cantilever pipes 74 are distributed with spray heads 75 which incline towards the dust collecting fins 55 from top to bottom; and the bottom of the cylinder is connected with a washing sewage discharge channel 57 and a waste liquid sedimentation tank at the periphery of the air inlet 52.

For a clear understanding of the principles and processes for implementing the functions of the above-summarized schemes, the following are described in detail: as can be seen from the figure, the purifying cylinder is butted with a waste gas exhaust pipe of a factory building and is suspended at a certain height, the exhaust fan arranged in the waste gas main exhaust system drives the purifying cylinder, and waste gas containing metal magnetic dust flows upwards from the gas inlet and is discharged from the gas outlet to the rear section. And because the spiral sheet-shaped guide fins are arranged in the cylinder, the waste flue gas is guided into spiral airflow simulating tornado after flowing through the air inlet, and therefore, the metal magnetic dust in the waste flue gas is accumulated outwards or thrown out towards the dust collecting fins along with the airflow under the radial centrifugal force. Meanwhile, based on the dust collecting fins and the electromagnet arranged inside and outside the cylinder, when the electromagnet is electrified to generate magnetism, the dust collecting fins are also synchronous with the magnetism, the metal magnetic dust is outwards accumulated by the spiral airflow, and the dust collecting fins can automatically capture and adsorb the dust particles. The separation and removal of the metal magnetic dust from the waste flue gas are effectively realized by utilizing the structural improvement of combining the centrifugal principle and the magnetic adsorption principle; the axial length of the cylinder body meets the thoroughness of centrifugal throwing and magnetic adsorption, namely when the air flow approaches the air outlet, the content of metal magnetic dust in the air flow reaches the ideal purification degree or is completely removed. When the dust adsorbed on the dust collecting fins reaches a certain amount to influence the adsorption efficiency, the purification cylinder can be switched to a short-time cleaning mode, and the method specifically comprises the steps of closing an exhaust fan and an air pipe electromagnetic valve to stop air flow, turning off an electromagnet to lose magnetism of the dust collecting fins, carrying out high-pressure water column washing on the dust collecting fins by arranging cantilever pipes and spray heads of the cantilever pipes, restoring the surface to be smooth, carrying out drainage collection on waste liquid obtained after washing, and precipitating and recovering a magnetic material. In addition, the illustration shows that the air flow channel and the washing sewage discharge channel in the purification cylinder are mutually isolated and do not interfere with each other, so that after the operation of a short cleaning mode is completed, the waste flue gas rotational flow electromagnetic purification mode can be switched back, an exhaust fan and an air pipe electromagnetic valve of the air duct system are opened, an electromagnet is electrified, and the waste flue gas enters the purification section and then is subjected to purification treatment of adsorption separation in the cylinder. The two modes of the purification cylinder are switched to operate repeatedly, so that the waste flue gas of a factory building can be efficiently and reliably treated.

In view of further detailed implementation structure, the middle shaft fixing column 511 is arranged in the cylinder 51, and is fixed in the inner side wall of the air inlet through the support legs at the bottom, but the support legs are arranged discretely, so that flow blocking influence on waste flue gas flowing upwards through the air inlet is avoided. The guide fins 54 are integrally connected to the fixed column of the central shaft, and may be single-rotation blades or double-rotation blades. What is clearly to be recognized is: the guide fins are fixedly arranged relative to the purification cylinder and only play a role in guiding, so that the original unidirectional upward flowing air flow is converted into spiral upward flowing air flow, and the air flow has a centrifugal effect. The airflow formed by the single-rotating blades is a single-strand spiral airflow, and the airflow formed by the double-rotating blades is two independent spiral airflows, so that the spiral performance and the centrifugal force of the airflow can be improved.

Referring to fig. 2 and 3, the dust collecting fins 55 are iron vertical plates formed by extending the inner wall of the cylinder centripetally and distributed at intervals, and the surfaces of the dust collecting fins are smooth. The design of the dust collecting part similar to the power supply radiating fin is adopted, the surface area for adsorbing metal magnetic dust can be increased, and waste liquid diversion during washing is facilitated.

In order to ensure the working efficiency of the cleaning mode, the cleaning machine 7 is a machine tool device with heating and pressurizing functions, one end of the machine tool device is connected to the municipal water supply 71, and the other end of the machine tool device is connected to the cleaning main pipe 72 and outputs the heating and pressurizing cleaning liquid to the cleaning main pipe. The cleaning liquid is branched to the cantilever pipes 74 through the cleaning main pipe 72, and a warm high-pressure water column of the cleaning liquid is discharged from the head 75. In order to allow the scouring cleaning to fully cover the inner wall of the cylinder (i.e., all the dust collecting fins), the cantilever tube needs to rotate within the cylinder. In the scheme, the fixed cleaning main pipe 72 is communicated with the freely rotating cantilever pipe 74 through the rotary sealing joint 73, and the cantilever pipe 74 adopts a passive driving design. The orientation of the spray head 75 is set at a 45 deg. angle to the corresponding cantilevered tube in the overhead view of the cartridge, such that the spray head is obliquely opposed to the surface of the dust collecting fin. Therefore, when the spray head sprays high-pressure water columns, the cantilever pipe is automatically rotated under the action of reverse force, and therefore self-cleaning treatment for cleaning and sweeping all dust collecting fins in the barrel can be achieved. In the illustrated embodiment, the nozzles are densely arranged at equal intervals in the vertical direction, and in practical application, the centrifugally adsorbed metal magnetic dust has a distribution difference of a large amount in the middle section and a small amount at the top and bottom ends, so the nozzles can also be arranged in a non-uniform distribution in the vertical direction.

Furthermore, as shown in fig. 2, the washing sewage discharge passage 57 is a funnel body nested inside and outside, the air inlet 52 is introduced into the cylinder body 51 from the middle of the bottom side of the funnel body, and the outer layer opening of the funnel body is integrally connected with the wall surface of the cylinder body and the like, and the inner layer opening of the funnel body corresponds to the radial profile of the rotation range of the cantilever pipe; the liquid outlet 751 of the funnel body is arranged at one side of the periphery of the air inlet in an inclined way, and the liquid outlet is connected with an electromagnetic valve for controlling the on-off. Therefore, the metal magnetic dust adsorbed on the dust collecting fins can slide into the washing sewage discharge channel downstream after being washed and eluted by the cleaning liquid sprayed out from the spray head, and the cleaning liquid is prevented from flowing back into the air inlet.

The liquid outlet 571 is opposite to and suspended at the open top of the waste liquid sedimentation tank 6. The depth of the waste liquid sedimentation tank 6 meets the recovery requirement of such dust materials, and the waste liquid sedimentation tank 6 is provided with a waste liquid treatment pipeline 61 for separating sediments and discharging sewage. Specifically, a half-depth grid plate is arranged in the waste liquid sedimentation tank, washing sewage enters a sedimentation state immediately after being discharged into the waste liquid sedimentation tank, solid substances sink to the bottom, the upper layer is separated to form basically clear sewage, and only when the basically clear sewage exceeds the height of the grid plate, the basically clear sewage overflows into a waste liquid treatment pipeline 61 and then flows into a city sewage system in a low-pollution mode.

As can be seen from the description of the structure and the function realization of the purification cylinder, the cantilever pipe in the equipment is designed passively, and the part related to electric control only comprises an electromagnet, an exhaust fan and an electromagnetic valve for controlling the on-off of a liquid discharge port. According to the concentration difference of dust particles in the waste flue gas, the switch control of time-interval power on and off can be carried out manually or simply in a program control mode. This part is not the focus of the present application and thus the detailed description is omitted.

To sum up, the embodiment detail and the function explanation of the self-cleaning rotational flow electromagnetic purification cylinder of the utility model show that the scheme has outstanding substantive characteristics and remarkable progress. The concrete embodiment is as follows: this purify a section of thick bamboo utilizes the electromagnet circular telegram to possess strong magnetic characteristic and the centrifugal principle of whirl, can effectively intercept, catch metal magnetic dust to utilize automatic controllable electro-magnet outage demagnetization and high-pressure warm water to regularly wash clearance, waste liquid deposit recovery material, improved the equipment life of back purification section and the recycle ratio of metal magnetic dust, reduced dust disposal's consumptive material and human cost.

In addition to the above embodiments, the present invention may have other embodiments, and all technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of the present invention.
