This waste gas spray device is different from the existing technology. Through the layered absorption mechanism, the acid mist waste gas mixed with dust of different particle sizes can be diverted after entering the spray tower body to avoid the dust of different particle sizes from mixing together and entering the packing layer at the same time, causing the packing layer to be blocked. At the same time, it effectively improves the quality of the acid mist waste gas spray treatment and ensures the efficient treatment of the waste gas.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 4 As shown, the utility model provides a water mist exhaust gas spraying device, comprising:

[0024] Spray tower 1;

[0025] The top of the spray tower 1 is connected to the waste gas tank 2 through a pipeline. The bottom of the left side of the spray tower 1 is fixedly connected to a bracket 3, and the top of the bracket 3 is fixedly connected to a processing mechanism 4;

[0026] The treatment mechanism 4 includes a water tower 41, a water pump 42, a connecting pipe 43, a water outlet pipe 44, a mist nozzle 45, a water inlet pipe 46 and a filter 47. The top of the bracket 3 is fixedly connected to the water tower 41, the bottom of the inner wall of the water tower 41 is fixedly connected to the water pump 42, the top of the water pump 42 is connected to the connecting pipe 43, the top and bottom of the right side of the connecting pipe 43 are connected to the water outlet pipe 44, the right side of the water outlet pipe 44 passes through the interior of the spray tower 1 and is fixedly connected to the mist nozzle 45, the top of the left side of the water tower 41 is connected to the water inlet pipe 46, the end of the water inlet pipe 46 away from the water tower 41 is connected to a water source, and the top and bottom of the inner cavity of the spray tower 1 are both horizontally fixedly connected to the filter 47.

[0027] refer to Figure 3 The bottom of the inner wall of the water tower 41 is fixedly connected to the surface of the water pump 42 and is sleeved on the surface of the water pump 42. The isolation cover 5 is used in conjunction with the water pump 42.

[0028] As a technical optimization solution of the present invention, the provision of the isolation cover 5 can assist the water pump 42 in working and play a protective role, thereby preventing the water pump 42 from being corroded and rusted due to being immersed in water for a long time.

[0029] refer to Figure 3The top and bottom of the right side of the water tower 41 are fixedly connected to the surface of the water outlet pipe 44 and are sleeved thereon. The sealing ring 6 is used in conjunction with the water outlet pipe 44.

[0030] As a technical optimization solution of the present invention, the provision of the sealing ring 6 can assist the outlet pipe 44 in working and at the same time play a sealing role, thereby avoiding leakage due to a gap between the outlet pipe 44 and the water tower 41.

[0031] refer to Figure 4 The inner cavity of the exhaust gas tank 2 is longitudinally fixedly connected with a grille net 7, which is used in conjunction with the exhaust gas tank 2.

[0032] As a technical optimization solution of the present invention, the provision of the grille 7 can assist the waste gas tank 2 in filtering, thereby avoiding the waste gas tank 2 being unable to filter the waste gas and causing pollution to the pipeline.

[0033] refer to Figure 2 The number of filter screens 47 is three and they are evenly distributed. The filter screens 47 are used in conjunction with the spray tower 1 .

[0034] As a technical optimization solution of the present invention, the setting of the filter screen 47 can assist the spray tower 1 in working and play a filtering role at the same time, thereby avoiding the spray tower 1 being unable to filter impurities and treat the waste gas.

[0035] refer to Figure 2 The shape of the mist nozzle 45 is conical, and the mist nozzle 45 is used in conjunction with the water pump 42 through the water outlet pipe 44 and the connecting pipe 43.

[0036] As a technical optimization solution of the present invention, the mist nozzle 45 is provided to maximize spraying, thereby avoiding the situation where the spraying efficiency does not meet the dust reduction requirements due to a small working range of the mist nozzle 45.

[0037] The working principle and usage process of the present invention are as follows: when in use, the exhaust gas enters the interior of the spray tower 1, and then the water pump 42 is started to work. The water pump 42 cooperates with the connecting pipe 43 to extract the water source inside the water tower 41. The connecting pipe 43 draws the water source into the interior of the water outlet pipe 44. The water outlet pipe 44 introduces water into the interior of the mist nozzle 45. The mist nozzle 45 sprays water vapor inside the spray tower 1 to mix with the exhaust gas. The dust in the exhaust gas is attached by water droplets and the dust is reduced. The exhaust gas rises and passes through multiple groups of filter screens 47 to filter impurities and enter the interior of the pipeline. The pipeline guides the exhaust gas to enter the interior of the exhaust tank 2 again. The exhaust tank 2 cooperates with the grille net 7 for secondary filtration treatment, so that water vapor impurities are reduced when the exhaust gas passes through, thereby achieving a good filtering effect.

[0038] To sum up: the water mist exhaust gas spraying device, through the use of a spray tower 1, an exhaust gas tank 2, a bracket 3, a treatment mechanism 4, a water tower 41, a water pump 42, a connecting pipe 43, a water outlet pipe 44, a mist nozzle 45, a water inlet pipe 46 and a filter screen 47, solves the problem that the exhaust gas treated by spraying in the existing spraying equipment cannot be filtered for a second time, resulting in the exhaust gas entering the next process and bringing in water vapor to block the pipeline.
