Description

Technical Field

[0001] This utility model belongs to the field of waste gas treatment technology, specifically a high-efficiency single-stage cyclone cabinet. Background Technology

[0002] In modern industrial production, gas purification and separation technology has always been a key link in improving production efficiency and ensuring environmental safety. The core working principle of the high-efficiency single-stage cyclone separator is based on centrifugal separation technology. Its main structure includes a cylindrical shell and a built-in cyclone separator. After the gas mixture enters the cyclone separator through the inlet, it will rotate at high speed under the action of the cyclone separator. Since the different components of the gas have different settling velocities under the action of centrifugal force, the heavier particles or droplets are thrown against the wall of the separator and slide down the wall surface, and finally discharged from the bottom, while the lighter gas is discharged from the top, thereby realizing gas-solid or gas-liquid separation.

[0003] Existing high-efficiency single-stage cyclone separators mainly have the following shortcomings:

[0004] Existing high-efficiency single-stage cyclone separators rely solely on simple inlet structures or a small number of blades to guide airflow rotation. This prevents the exhaust gas entering the separator from forming a highly efficient and stable cyclone effect. Consequently, particulate matter in the dust-laden exhaust gas is difficult to separate effectively under the cyclone action. Relying solely on a single cyclone method for exhaust gas purification cannot comprehensively and effectively treat pollutants of different properties and particle sizes. For some pollutants with smaller particle sizes or exhaust gases with complex compositions, the purification effect is poor. Utility Model Content

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] like Figures 1-4 As shown, this utility model provides a technical solution:

[0025] A high-efficiency single-stage vortex cabinet includes:

[0026] The cabinet 1 has an air inlet 2 at the center of its upper surface and a spiral groove 3 on the inner wall of the air inlet 2. A vortex structure 4 is located near the center of the cabinet 1. The vortex structure 4 includes a vortex frame 401, which is located near the center of the cabinet 1. Multiple vortex blades 402 are arranged in a ring at the center of the vortex frame 401. Dust-laden gas enters the cabinet 1 through the air inlet 2. The spiral groove 3 on the inner wall of the air inlet 2 causes the gas to move in a spiral direction, creating an initial vortex effect. After entering the cabinet 1, the gas impacts the vortex blades 402 located in the vortex structure 4. Under the action of the blades, the gas further strengthens its rotational motion, forming a strong vortex. This causes large particles in the gas to move towards the edge of the cabinet 1 under the action of centrifugal force.

[0027] A filter structure 5 is located at the lower center of the interior of cabinet 1. The filter structure 5 includes a mounting bracket 501, which is positioned at the lower center of the front face of cabinet 1. Three carrying boxes 502 are arranged vertically at the center of the front face of the mounting bracket 501. One end of each of the three carrying boxes 502 passes through the front face of the mounting bracket 501 and into the interior of cabinet 1. A water-washable filter layer 503 is located at the center of the upper mounting bracket 501 inside cabinet 1. A packing layer 504 is located at the center of the carrying boxes 502 inside cabinet 1. Glass fiber 505 is located at the lower center of the carrying boxes 502 inside cabinet 1. When gas descends, it first encounters the water-washable filter layer 503. Through the adsorption and rinsing action of water, some dust and other impurities are removed. Water can lower the gas temperature and dissolve or adsorb particulate pollutants in the water, achieving a preliminary filtration and purification effect. The gas washed by water enters the packing layer 504, which is usually composed of materials with a large specific surface area such as activated carbon and molecular sieves. This further adsorbs fine particles, organic matter, and some harmful gases in the gas, resulting in more refined purification. Finally, the gas passes through glass fiber 505, which can form a dense fiber network structure. With its complex and tortuous pores, it can effectively intercept the extremely fine particles that remain after passing through the previous purification unit, ultimately achieving a high degree of gas purification.

[0028] A spray structure 6 is located at the lower center of one side of cabinet 1. The spray structure 6 includes a water collection tank 601, which is located at the lower center of one side of cabinet 1. A self-priming pump 602 is located at the center of the lower inner wall of the water collection tank 601. The output end of the self-priming pump 602 passes through the upper inner wall of the water collection tank 601 and connects to the interior of cabinet 1 at the upper part of one side wall of cabinet 1. A water receiving tank 604 is located at the center of the lower end of cabinet 1. A circulation pump 603 is located at the upper center of one inner side wall of the water collection tank 601. The input end of the circulation pump 603 passes through one inner side wall of the water collection tank 601. The side wall of the water receiving tank 604 extends to the interior of the water receiving tank 604 at the lower part of the side wall. The water in the water collection tank 601 is drawn out by the self-priming pump 602 and transported to the interior of the cabinet 1 for spraying through the pipeline. The sprayed water forms a mist and comes into full contact with the gas after swirling. The water can further capture residual dust and other pollutants in the gas, improving the purification efficiency. At the same time, the sprayed water is recycled. The water in the water receiving tank 604 is pumped back to the water collection tank 601 by the circulation pump 603, so that the entire spraying system can work continuously.

[0029] A discharge structure 7 is provided at the center of the lower end face of the cabinet 1. The discharge structure 7 includes a discharge pipe 701, which is located at the center of the lower end face of the cabinet 1. A stabilizing frame 702 is provided at the center of the outer wall of the discharge pipe 701. A gate 703 is provided at the center of the inside of the discharge pipe 701. A control rod 704 is provided at the center of one side wall of the stabilizing frame 702. One end of the control rod 704 passes through the front end face of the stabilizing frame 702, the front end face of the discharge pipe 701, and the front end face of the control rod 704, leading to the inside of the control rod 704. An exhaust port 705 is provided at the lower center of one side wall of the cabinet 1. The treated gas is discharged through the exhaust port 705 and released into the atmosphere. Liquid generated during the purification process will settle at the lower end of the cabinet 1. The discharge of liquid is controlled by operating the gate 703 through the control rod 704.

[0030] The working principle of this utility model is as follows:

[0031] Dust-laden gas enters the cabinet 1 through inlet 2. The spiral grooves 3 on the inner wall of inlet 2 cause the gas to move in a spiral direction, creating an initial swirling effect. After entering the cabinet 1, the gas impacts the swirling blades 402 located in the swirling structure 4. Under the action of the blades, the gas further intensifies its rotational motion, forming a strong swirling flow. During high-speed rotation, particles in the airflow are subjected to centrifugal force. Larger particles, due to the greater centrifugal force, gradually move towards the inner wall of the cabinet 1, while smaller particles and most of the gas remain in the central area of ​​the airflow. The initial particle separation provides a good fluid state for subsequent filtration. Water for purification is stored in the water collection tank 601. The water in the water collection tank 601 is drawn out by the self-priming pump 602 and transported to the inside of the cabinet 1 for spraying through the pipeline. The sprayed water forms a mist. The atomized water mixes and contacts the gas thoroughly, increasing the contact area. The water droplets adsorb and encapsulate residual dust and fine particles in the gas, as well as some soluble harmful gases, removing pollutants. The water can further capture residual dust and other pollutants in the gas, improving purification efficiency.

[0032] The gas, after being swirled and sprayed, flows downwards to the water-washed filter layer 503. The water-washed filter layer 503 is typically filled with packing material with a large surface area and adsorption capacity, adsorbing dust and other pollutants in the gas. Some pollutants are carried into the liquid collection area below by the flushing action of the water, reducing dust concentration. Simultaneously, it has an impact and trapping effect on particles, removing some dissolved substances, dust, and harmful gases from the gas, thus reducing the pollutant content. The gas passing through the water-washed filter layer 503 then passes through the packing layer 504, which is composed of materials with strong adsorption capacity, such as activated carbon, molecular sieves, and porous ceramics. With a large specific surface area and numerous micropores and surface active sites, tiny particulate matter and harmful gas molecules in the gas are adsorbed on the surface of the packing layer 504 or react chemically with the packing and are fixed on the packing surface, improving the purification level of the gas. The gas continues to descend to the glass fiber 505 section, where the fiber filaments formed by the glass fiber 505 interweave to form a dense filter network. When the gas passes through, extremely fine particles, aerosols and other pollutants are intercepted, settled or adsorbed on the fiber surface by the fiber filaments, making it difficult to penetrate the glass fiber 505 layer, ultimately making the gas reach a relatively clean level and completing efficient multi-stage filtration and purification.

[0033] After multiple purification processes, the gas that meets the emission standards is discharged from the equipment through the exhaust port 705 and released into the subsequent treatment process or the atmospheric environment. During the purification process, the liquid that settles to the bottom of the cabinet 1 is controlled by the opening and closing of the gate 703 operated by the control rod 704, thereby controlling the discharge of the liquid. At the same time, the water in the water receiving tank 604 is pumped back to the water collection tank 601 by the circulation pump 603, so that the entire spraying system can work continuously and the sprayed water can be recycled.

[0034] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
