Description

Technical Field

[0001] The present invention relates to the technical field of industrial waste gas purification, and particularly to an industrial waste gas deodorization and purification spray tower. Background Art

[0002] Industrial waste gas deodorization and purification spraying is a technology that uses a spray tower device to remove malodorous molecules and harmful gases in waste gas by spraying deodorants or absorbent liquids. The working principle of the spray tower is based on the basic principle of gas-liquid mass transfer. When the waste gas enters the spray tower, the spray system evenly sprays down a liquid (usually water or an aqueous solution added with specific chemical agents) to form fine droplets. These droplets come into full contact with the rising waste gas. Through inertial collision, interception, and coagulation, pollutants such as paint mist particles and water-soluble organic waste gas in the waste gas are captured by the droplets and dissolved or adsorbed therein, thereby achieving the preliminary purification of the waste gas. For malodorous gases, the spray tower deodorant acts on the malodorous molecules in the waste gas through physical adsorption, chemical reaction, or biodegradation, effectively removing or transforming these harmful components.

[0003] At present, industrial waste gas deodorization and purification spray equipment can be single-layer spraying or multi-layer spraying. The space for single-layer spraying to contact and adsorb and purify the waste gas is small. In a multi-layer spraying in one space, the upper-layer spraying overlaps with the lower-layer spraying, and there is mutual interference between the two layers of spraying, resulting in large and heavy particle size after the lower-layer spraying water mist is superimposed on the upper-layer water mist; static spraying only has the collision between the spraying force and the waste gas, and the fusion and adsorption force between the spraying water mist and the waste gas is small; the spray tower uses the air inlet to directly introduce the waste gas into the spraying space in the tower. Limited by the position and size of the air inlet, the waste gas flows unevenly in the spray tower, so the waste gas contacts the spraying water mist unevenly, affecting the uniformity and effect of spray purification.

The waste water generated by spraying in the lower-layer spray area falls into the reservoir 3 and is filtered by the water filter plate 24.

[0025] Further, the second spraying mechanism includes a connecting pipe 72, a storage tank 73, a first spraying pump 74 and a return pipe 75. A storage tank 73 is provided on one side of the spray tower body 1. The lower end on one side of the storage tank 73 is connected to the input end of the first spraying pump 74 through a connecting pipe 72, and the output end of the first spraying pump 74 is connected to the spray disk 7 through a connecting pipe 72.

When the valve is opened, the waste liquid generated by spraying in the upper-layer spray area is filtered and returned to the storage tank 73 through the return port and the return pipe 75.

[0026] Further, the intake mechanism 9 includes an intake duct 91, an upward air supply port 92, a centralized deflector 93, and a lifting deflector 94. Inside the spray tower body 1 below the communication disk 8, there is an intake duct 91 connected to the air inlet 10. The intake duct 91 is arranged as a circular pipe and is horizontally disposed at the middle position in the horizontal direction of the spray tower body 1. The spaces of the spray tower body 1 on both sides of the intake duct 91 are interconnected. Most of the sprayed water in the lower spray area falls inside the spray tower body 1 outside the intake duct 91. The top of the intake duct 91 is provided with an upward air supply port 92. Inside the intake duct 91, there are several centralized deflectors 93. The centralized deflectors 93 are arranged in a horn-shaped structure. At the bottom of the intake duct 91 between two adjacent centralized deflectors 93, there is a lifting deflector 94. One of the centralized deflectors 93 is arranged inside the air inlet 10. There is a perforation in the middle of the intake duct 91. The connecting rod 11 passes through the intake duct 91 from the perforation. The bottom of the intake duct 91 is arranged as an inclined surface structure with the end towards the perforation being lower, that is, the two ends of the bottom of the intake duct 91 are high and the middle is low. Part of the wastewater entering the intake duct 91 during spraying quickly drains out from the perforation. A heat exchange mechanism is provided on the intake duct 91. Industrial waste gas enters the intake duct 91 from the air inlet 10. The waste gas is deflected and centralized by the centralized deflectors 93 to form a centralized air flow flowing inside the intake duct 91. The centralized air flow is dispersed. The downward dispersed air flow is lifted by the lifting deflector 94 to form an upward air flow. The upward air flow and the upward dispersed air flow rise and are sent into the lower spray area through the upward air supply port 92 at the top of the intake duct 91. The waste gas is centrally deflected multiple times inside the intake duct 91, and the intake air flow passes through the entire intake duct 91. The upward air supply port 92 at the top of the intake duct 91 corresponds to the lower spray area. The upward air supply port 92 supplies air to the lower spray area in a large space and evenly, and the waste gas is sprayed more evenly.

[0027] Further, the heat exchange mechanism includes a heat exchange pipe network 95, a heat exchange inlet 96, and a heat exchange outlet 97. Inside the intake duct 91, there is a heat exchange pipe network 95.

One end of the heat exchange pipe network 95 is connected to the heat exchange inlet 96, and the other end of the heat exchange pipe network 95 is connected to the heat exchange outlet 97. The heat exchange inlet 96 is connected to a low-temperature water supply device through a pipeline, and the heat exchange outlet 97 is connected to a high-temperature water storage device through a pipeline. When high-temperature waste gas flows through the intake duct 91, low-temperature water is transported from the heat exchange inlet 96 to the heat exchange pipe network 95. The low-temperature water absorbs the heat of the high-temperature waste gas inside the heat exchange pipe network 95. The high-temperature water after heat exchange inside the heat exchange pipe network 95 is discharged from the heat exchange outlet 97, and the waste heat of the high-temperature waste gas is recovered through large-space flow heat exchange.

[0028] Furthermore, the purification mechanism includes a filter screen 21, purification packing 22 and a water-vapor separation membrane 23. Inside the spray tower body 1 above the spray disc 7, there is a filter screen 21. Inside the spray tower body 1 above the filter screen 21, there is purification packing 22. Inside the spray tower body 1 above the purification packing 22, there is a water-vapor separation membrane 23. The water-vapor separation membrane 23 is arranged below the fan blade 17. The filter screen 21 uses a precision filter screen, and the purification packing 22 uses activated carbon packing.

[0029] Furthermore, a first cleaning brush 18 is arranged on the rotating rod 4 below the filter screen 21, and a second cleaning brush 19 is arranged on the rotating rod 4 above the water filter plate 24. The first cleaning brush 18 on the rotating rod 4 cleans the filtering surface of the filter screen 21, and the second cleaning brush 19 on the rotating rod 4 cleans the water filtering surface of the water filter plate 24.

[0030] Furthermore, a dispersion air guide plate 20 is arranged on the rotating rod 4 above the rising port 51. The dispersion air guide plate 20 is arranged in a downward convex structure. The waste gas rising in the rising port 51 encounters the dispersion air guide plate 20 on the rotating rod 4 and is guided and dispersed in the upper spray area, and the waste gas spreads more evenly in the upper spray area.

[0031] Even further, an annular sealing groove 52 is arranged on the circumferential side wall of the flow dividing partition 5. The inner wall of the spray tower body 1 is provided with an annular sealing platform. The sealing platform is arranged inside the sealing groove 52. The sealing platform seals and supports the flow dividing partition 5. The flow dividing partition 5 and the inner wall of the spray tower body 1 are sealed through the sealing platform and the sealing groove 52. Closing the valve on the return pipe 75 enables the horn-shaped flow dividing partition 5 to accumulate the spray liquid in the upper spray area above, increasing the residence time of the spray liquid in the upper spray area.

[0032] The usage method of this embodiment is as follows: The waste gas generated by the operation of industrial equipment is connected to the air inlet 10 through a pipeline. The industrial waste gas enters the intake pipeline 91 from the air inlet 10. The waste gas is guided and concentrated by the centralized deflector 93 to form a concentrated air flow and flows in the intake pipeline 91. The concentrated air flow is dispersed. The downward dispersed air flow is lifted by the lifting deflector 94 to form an upward air flow. The upward air flow and the upward dispersed air flow are sent upward into the lower spray area from the upward air supply port 92 at the top of the intake pipeline 91. The waste gas is centrally deflected multiple times in the intake pipeline 91. The intake air flow passes through the entire intake pipeline 91. The upward air supply port 92 at the top of the intake pipeline 91 corresponds to the lower spray area. The upward air supply port 92 supplies air to the lower spray area in a large space and evenly, and the air rises and circulates. The waste gas spraying is more uniform. The heat exchange pipe network 95 is arranged inside the intake pipeline 91. When the high-temperature waste gas flows through the intake pipeline 91, the low-temperature water is transported to the heat exchange pipe network 95 from the heat exchange inlet 96. The low-temperature water absorbs the heat of the high-temperature waste gas in the heat exchange pipe network 95. The high-temperature water after heat exchange in the heat exchange pipe network 95 is discharged from the heat exchange outlet 97. The high-temperature waste gas realizes large-space circulation heat exchange and waste heat recovery. The waste gas enters the spray tower body 1 evenly from the upward air supply port 92 and rises and circulates. The servo motor 16 drives the rotating rod 4 to rotate, driving the fan blade 17, the first cleaning brush 18, the shunt partition 5, the spray pipe 6, the connecting rod 11 and the second cleaning brush 19 to rotate synchronously inside the spray tower body 1. Under the action of the second spray pump 14, the waste gas purification water in the reservoir 3 is transported to the spray pipe 6 through the water supply pipe 13, the rotary joint 12, the connecting rod 11 and the connecting disk 8. The waste gas purification water is sprayed on the lower spray area inside the spray tower body 1 through the first nozzles 61 on the spray pipe 6. Since the spraying directions of the first nozzles 61 on the spray pipe 6 are set towards the surroundings, the first nozzles 61 on the spray pipe 6 have a downward and upward spraying range, that is, the lower spray three-dimensional space structure. The spraying radiation space in the lower spray area is large. The spray pipe 6 is installed on the rotating rod 4 through the connecting disk 8 and rotates during the spraying process. The lower spray rotation has a greater spraying shear force. The two are combined. The waste gas flowing through the large-space spray area in the lower layer has a larger surface area of the gas-liquid contact area, which is beneficial to the adsorption, diffusion and chemical reaction of the waste gas by spraying, and improves the purification efficiency of the waste gas in the lower spray area. The waste gas in the lower spray area enters the upper spray area from the upward port 51. The waste gas rising from the upward port 51 is deflected and dispersed in the upper spray area by the dispersion air guide plate 20 on the rotating rod 4. Under the action of the first spray pump 74, the waste gas purification liquid in the storage tank 73 is transported to the spray disk 7 through the connecting pipe 72 and sprayed on the upper spray area through the second nozzles 71 at the bottom of the spray disk 7. The spray pipe 6, the connecting disk 8 and the shunt partition 5 form a spray rack. The shunt partition 5 separates the lower spray area and the upper spray area formed by the spray rack and the spray disk 7. The spray rack is arranged in the lower spray area, and the spray disk 7 is arranged in the upper spray area. The spray tower adopts double-layer shunt separation spraying. The double-layer spraying diffusion space is larger. The shunt separation between the two layers of spraying does not interfere, avoiding double-layer spraying overlap.The air flow passing through the upper spray zone rises and passes through the filter screen 21, the purification filler 22 and the water vapor separation membrane 23. After being filtered, adsorbed and purified, and the water vapor is separated, it is discharged from the purification outlet 2 out of the spray tower body 1. The wastewater generated by spraying in the lower spray zone falls into the reservoir 3 and is filtered by the water filter plate 24. Part of the wastewater enters the intake pipe 91 and is discharged through the perforations. The waste liquid generated by spraying in the upper spray zone is filtered and refluxed to the storage tank 73 through the reflux port and the reflux pipe 75. The first cleaning brush 18 on the rotating rod 4 cleans the filtering surface of the filter screen 21, and the second cleaning brush 19 cleans the water filtering surface of the water filter plate 24.,
