Description

Technical Field

[0001] The utility model relates to the technical field of waste gas purification towers, in particular to a waste gas purification tower for chemical industrial safety production. Background Technique

[0002] Chemical industrial waste gas refers to the toxic and harmful gases discharged from chemical factories during chemical production. Chemical industrial waste gas often contains many types of pollutants, with complex physical and chemical properties and different toxicities, seriously polluting the environment and affecting human health. According to the form of pollutants, chemical industrial waste gas can be divided into particulate pollutants and gaseous pollutants. Particulate pollutants include dust particles, dust, soot, fog dust, coal dust, etc.; during the process of chemical industrial safety production, a purification tower is required to spray and treat the chemical industrial waste gas containing particulate pollutants before it can be discharged.

[0003] After retrieval, the Chinese patent publication number CN217855264U discloses a chemical industrial waste gas purification tower for chemical industrial safety production. The patent includes a tower body. The inside of the tower body is divided into a spray chamber and a circulating water tank chamber from top to bottom. One side of the tower body is communicated with an air inlet pipe, and the top of the tower body is communicated with an exhaust pipe. The front side of the tower body is communicated with a liquid injection pipe, and the lower part of one side of the tower body is communicated with a circulating pipe. The lower part of one side of the tower body is fixedly connected with a bearing plate, and three connecting pipes penetrate through the upper part of one side of the tower body. Through the circulating pipe, water pump, filter barrel, cashmere cotton, liquid inlet pipe, liquid discharge pipe, connecting pipe and spray head, the sprayed water can be filtered and circulated, reducing the waste of water resources. And through the swirl mechanism composed of a circular ring, a disc and an inclined plate, the sprayed water can be swirled, increasing the contact probability with the particles in the waste gas, thereby increasing the purification effect of the waste gas. However, during the use of this device, when the real-time processing amount of the waste gas changes, the spraying area cannot completely cover the distribution area of the waste gas, and the particles in the waste gas will adhere to the swirl plate, affecting the processing effect, and the practicability needs to be improved.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0025] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0026] The following further describes the present utility model in conjunction with the accompanying drawings:

[0027] As Figure 1 — Figure 6 shown, an exhaust gas purification tower for chemical industrial safety production includes a tower body 101. One side of the bottom of the tower body 101 is bolted with an air inlet pipe 102, and the top of the tower body 101 is bolted with an exhaust pipe 103. A liquid injection port 104 is opened on one side of the bottom of the tower body 101. A circulation mechanism is installed on one side of the bottom of the tower body 101. A plurality of groups of spray mechanisms are arranged in the tower body 101, and a swirl mechanism is installed on the spray mechanism. The spray mechanism includes a liquid spray pipe 301. An installation groove 302 is opened at the water outlet end of the liquid spray pipe 301. A pressure plug 303 is bolted in the liquid spray pipe 301. A conical block 304 is bolted to the bottom of the pressure plug 303. A spray head 305 is slidably arranged in the installation groove 302. A conical groove 306 with the same shape as the conical block 304 is opened at the water inlet end of the spray head 305. By moving the spray head 305 up and down, the size of the gap between the conical groove 306 and the conical block 304 changes, so as to control the pressure of the liquid, making the liquid flow sprayed out of the spray head 305 have a greater pressure and increasing the contact probability with the exhaust gas particles at the position of the swirl plate 402;

[0028] The swirl mechanism includes a fixed ring 401. A plurality of annularly arranged swirl plates 402 are bolted in the fixed ring 401. The fixed ring 401 and the swirl plates 402 are made of lightweight materials. An adjusting component is installed at the top of the fixed ring 401, and the adjusting component is used to control the gap between the conical block 304 and the conical groove 306 according to the real-time processing amount of the exhaust gas.

[0029] In this embodiment, the adjusting component includes a sliding rod 406 bolted to the top of the fixed ring 401. A fixed block 405 is slidably connected to the sliding rod 406. The fixed block 405 is bolted to the inner wall of the tower body 101. A connecting rod 407 is bolted to the top of the sliding rod 406. The connecting rod 407 is bolted to the side of the spray head 305. When the real-time exhaust gas processing amount becomes larger, the air pressure will lift the swirl plate 402. The swirl plate 402 lifts the connecting rod 407 through the fixed ring 401 and the sliding rod 406, and the connecting rod 407 lifts the spray head 305, reducing the gap between the conical block 304 and the conical groove 306, making the water flow speed faster, so as to increase the contact probability with the exhaust gas particles at the position of the swirl plate 402.

[0030] In this embodiment, a bracket 307 is bolted to the water outlet end of the spray head 305. A dispersing fan blade 308 is rotatably connected in the bracket 307. After the water flow enters the spray head 305 from the liquid spray pipe 301, it pushes the dispersing fan blade 308 to rotate at the water outlet end and forms a larger circular coverage area. And the greater the water flow speed, the larger the formed circular coverage area.

[0031] In this embodiment, ribs 403 are integrally formed and connected to the top of the swirl plate 402. The ribs 403 are used to guide the sprayed liquid to impact the bottom of the adjacent swirl plate 402.

[0032] In this embodiment, a central block 404 is provided at the center position of the fixed ring 401. The central block 404 is connected to the swirl plate 402 by bolts. The setting of the central block 404 enhances the structural strength of the swirl plate 402.

[0033] In this embodiment, the circulation mechanism includes a circulation pipe 201. The circulation pipe 201 is connected to the bottom of the tower body 101 by bolts. The water outlet end of the circulation pipe 201 is connected to a purification barrel 202 by bolts. Purification materials such as activated carbon and cashmere cotton are stored in the purification barrel 202 for purifying the liquid polluted by waste gas. The water outlet end of the purification barrel 202 is connected to a liquid outlet pipe 203 by bolts. A water pump 204 is connected to the side of the tower body 101 by bolts. The liquid outlet pipe 203 leads to the liquid inlet end of the water pump 204. The water outlet end of the water pump 204 is connected to a water supply pipe 205 by bolts. The liquid spraying pipe 301 communicates with the water supply pipe 205.

[0034] Working principle: When the device is in use, first inject the sprayed liquid into the tower body 101 through the liquid injection port 104, turn on the water pump 204, and introduce the waste gas generated during chemical production into the tower body 101 through the air inlet pipe 102, moving upward from bottom to top inside the tower body 101. The water pump 204 pumps the water flow in the tower body 101 into the water supply pipe 205, and it is sprayed out through the liquid spraying pipe 301 and the spray heads 305. When the waste gas flows out through the gaps of the swirl plate 402, the liquid sprayed from above separates the waste gas from the particulate matter and purifies the waste gas. When the waste gas treatment volume increases, the air pressure will lift the swirl plate 402. The swirl plate 402 lifts the connecting rod 407 through the fixed ring 401 and the sliding rod 406, and the connecting rod 407 lifts the spray head 305, reducing the gap between the conical block 304 and the conical groove 306, increasing the water flow speed, so that the liquid flow sprayed from the spray head 305 has a greater pressure. After the water flow enters the spray head 305 from the liquid spraying pipe 301, it pushes the dispersion fan blade 308 to rotate at the water outlet end and forms a larger circular coverage area. Moreover, the greater the water flow speed, the larger the formed circular coverage area, thereby increasing the contact probability with the waste gas particles at the position of the swirl plate 402. At the same time, the greater the speed of the sprayed water flow, when the water falls on the ribs 403, the splashed water can clean the bottom of the swirl plate 402, preventing the substances in the waste gas from sticking to the bottom of the swirl plate 402 and affecting the waste gas purification effect.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
