Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a spray tower body for waste gas treatment. Background Art

[0002] The spray tower exists as a treatment equipment for environmental waste gas treatment. According to the working principle, it is divided into circulating water spray tower, alkali spray tower, acid spray tower (alias: pickling tower). According to the tower material, it is divided into FRP spray tower, PP spray tower, stainless steel spray tower. According to the different properties of the waste gas, reasonable spray materials and spray processes are selected. When dust-containing waste gas or oil-containing waste gas passes through the spray tower, liquid media are sprayed out from the appropriate position inside the tower (depending on the design). Some are alkali solutions, and some are sulfuric acid solutions. If the waste gas contains acid, alkali spray is selected to neutralize the acid. If the waste gas contains If it contains alkalinity, sulfuric acid solution is selected for absorption. The specific choice of acid or alkali solution depends on the nature of the waste gas and the company's own situation. Waste gas without acid or alkali but containing oil and dust can be treated by spraying with circulating water solution. When the waste gas enters from the bottom of the tower, it comes into contact with the spray medium sprayed from the spray tower. After contact, the waste gas or oil is wrapped by water droplets. The water droplets wrapped by the pollutants collide again to increase the surface area and increase the gravity. When the gravity increases, the water droplets wrapped by the pollutants fall to the bottom of the spray tower under the influence of gravity. The heavier pollutants sink to the bottom of the tower, and the lighter pollutants float on the surface of the circulating water.

[0003] During the use of the spray tower, the waste gas treatment efficiency can be as high as over 90%, but there is always waste gas that can escape from the water mist, resulting in discomfort when passing by the chemical plant during the exhaust process. At the same time, in the process of mass production, a small amount of waste gas, discharged for a long time, still causes great damage to the environment, which is not conducive to long-term environmentally friendly production. In the process of waste gas treatment by the spray tower, in order to improve efficiency, most of the multi-layer spraying method is used to increase the density of the water curtain, but this treatment efficiency will not increase linearly with the increase of the water curtain amount. Therefore, controlling the mixing time of the waste gas and disinfection water relative to the increase of the water curtain amount can effectively improve the efficiency. For this reason, we propose a spray tower body for waste gas treatment. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figures 1 to 4The utility model provides a technical solution: a spray tower body for waste gas treatment, including a spray tower 1, an inner cavity fixed sleeve of the spray tower 1 is provided with a support ring 2, a movable ring 3 is supported on the support ring 2, a support sleeve 8 is located on the outside of the movable ring 3, an electromagnetic block 7 is located on the outside of the permanent magnet block 4, and an air inlet pipe 6 is located below the movable ring 3. The electromagnetic block 7 is provided to cooperate with the permanent magnet block 4 to control the rotation of the permanent magnet block 4, and the power supply of the electromagnetic block 7 is used to control the change of the magnetic field of the electromagnetic block 7, thereby controlling the permanent magnet block 4 to rotate. After the permanent magnet block 4 rotates, the movable ring 3 and the drainage block 5 are driven to rotate. By utilizing the rotation of the drainage block 5, during use, the waste gas and water mist in the inner cavity of the spray tower 1 can form a vortex airflow, so that the waste gas and water mist are fully mixed, and the efficiency of disinfection is effectively improved. The movable ring 3 is internally fixedly supported with a permanent magnet block 4 in a ring shape, and the inner side of the movable ring 3 is fixedly sleeved with a drainage block 5. The outer side of the spray tower 1 is fixedly connected with an air inlet pipe 6, and the inner cavity of the air inlet pipe 6 is provided with a one-way flow limiting valve. The outer side of the spray tower 1 is fixedly sleeved with a support sleeve 8, and the inner side of the support sleeve 8 is fixedly sleeved with an electromagnetic block 7. After the exhaust gas enters the inner cavity of the spray tower 1, the electromagnetic block 7 is used to control the rotation of the permanent magnet block 4, so that the permanent magnet block 4 rotates in the inner cavity of the spray tower 1. The rotation of the permanent magnet block 4 will drive the drainage block 5 to rotate. The rotation of the drainage block 5 will guide the air in the inner cavity of the spray tower 1 to form a cyclone, which will drive the exhaust gas and water mist to rotate in the inner cavity of the spray tower 1, which can effectively limit the escape speed of the exhaust gas, make the exhaust gas and water mist fully mixed, and facilitate the use of the equipment.

[0021] An exhaust sleeve 9 is fixedly installed on the top of the spray tower 1, and a sealing sleeve 10 is movably mounted on the inner side of the exhaust sleeve 9. Exhaust grooves are provided on the outer sides of the sealing sleeve 10 and the exhaust sleeve 9. The inner cavity of the sealing sleeve 10 and the inner cavity of the exhaust pipe 11 are connected to each other. The setting of the sealing sleeve 10 plays a role in sealing the exhaust sleeve 9. After the sealing sleeve 10 blocks the exhaust sleeve 9, the exhaust gas cannot escape in time and can only be fully mixed with the water mist in the inner cavity of the spray tower 1, which can effectively improve the efficiency of exhaust gas treatment and facilitate the use of the equipment. When the exhaust groove of the sealing sleeve 10 and the exhaust pipe 11 are not parallel, the sealing sleeve 10 and the exhaust sleeve 9 are in a blocked state. A driving motor 12 is supported on the top of the exhaust sleeve 9, and the bottom end of the output shaft of the driving motor 12 is fixedly connected to the sealing sleeve 10, and the outer side of the exhaust sleeve 9 is fixedly connected to the exhaust pipe 11.

[0022] The interior of the spray tower 1 is fixedly equipped with a spray rack 15, which is located above the drainage block 5. The top of the water supply pipe 14 is fixedly connected to the outside of the spray rack 15. The water pump 13 is controlled to start, and the water pump 13 is used to continuously pump the disinfecting water in the inner cavity of the water tank 16 upward, and continuously transport it upward through the water supply pipe 14, so that the disinfecting water enters the spray rack 15, and then the disinfecting water is atomized through the nozzle under the spray rack 15, so that the disinfecting water is sprayed downward in the form of water mist, so that the water mist continues to fall from top to bottom in the inner cavity of the spray tower 1, and the bottom surface of the spray tower 1 is fixedly connected to the water tank 16, and the water pump 13 is fixedly installed on the outside of the water tank 16, and the water supply pipe 14 is fixedly connected to the outside of the output end of the water pump 13.

[0023] In summary, when the spray tower for waste gas treatment is used, first control the water pump 13 to start, and use the water pump 13 to continuously pump the disinfecting water in the inner cavity of the water tank 16 upward, and continuously transport it upward through the water supply pipe 14, so that the disinfecting water enters the spray rack 15, and then the disinfecting water is atomized through the nozzle under the spray rack 15, so that the disinfecting water is sprayed downward in the form of water mist, and the water mist is continuously transported from top to bottom in the inner cavity of the spray tower 1, and then the waste gas is continuously transported to the inner cavity of the spray tower 1 through the air inlet pipe 6. A one-way valve is arranged inside the air inlet pipe 6. After the waste gas enters the inner cavity of the spray tower 1, the electromagnetic block 7 is used to control the rotation of the permanent magnet block 4. The permanent magnet block 4 rotates in the inner cavity of the spray tower 1. The permanent magnet block 4 drives the drainage block 5 to rotate during its rotation. The rotation of the drainage block 5 guides the air in the inner cavity of the spray tower 1 to form a cyclone. The cyclone drives the exhaust gas and water mist to rotate in the inner cavity of the spray tower 1, so that the exhaust gas and the disinfection water can be fully mixed, thereby improving the efficiency of exhaust gas disinfection. At the same time, the output shaft of the driving motor 12 can control the rotation of the sealing sleeve 10. When the side opening of the sealing sleeve 10 and the exhaust pipe 11 do not overlap, the exhaust gas cannot be discharged, thereby effectively limiting the mixing time of the exhaust gas and the disinfectant, thereby effectively improving the disinfection efficiency of the equipment.
