Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a water spray device for treating waste gas in a paint booth. Background Art

[0002] The full name of the paint room is the spray paint room. It is a device that sprays paint and dyes the surface of the equipment and dries it. It not only makes the equipment beautiful, but also protects the items. Several factors to measure the paint room include brightness, air flow, filtration effect, wall sealing effect, positive pressure, sealing effect of the heating system, and heating speed. The paint room will produce harmful gases during the drying process, the main components of which are organic substances such as benzene, toluene, xylene, and non-methane total hydrocarbons.

[0003] The paint booth exhausts exhaust gas through a fan, and in order to treat the dust and harmful gases in the exhaust gas, most of them are treated by spraying and settling. The common spraying method is usually to install a spray device in the exhaust pipe, and to treat the dust and harmful gases in the exhaust gas through atomized water droplets during the exhaust gas discharge process. However, the spray equipment is directly fixed in the exhaust pipe, and the spray direction of the spray equipment is fixed, which is prone to dead angles. It is impossible for the atomized water droplets to contact and fall with the dust and harmful gases in the exhaust gas in all directions, which has certain limitations. For this reason, we propose a water spray equipment for exhaust gas treatment in paint booths to solve the above problems. Utility Model Content

[0022] 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.

[0023] See also Figure 1 , 23. The utility model provides a technical solution: a water spray device for treating exhaust gas in a paint booth, which is applied to a paint booth body 1. The back of the paint booth body 1 is fixedly connected with a hollow connecting seat 2, and an atomizing treatment pipe 3 is fixedly installed on the top of the hollow connecting seat 2. A connecting end 4 is fixedly installed on the top of the atomizing treatment pipe 3, and one end of the connecting end 4 is fixedly connected to the air inlet of an exhaust fan 5. An upper spray rack 8 and a lower spray rack 9 are movably installed inside the atomizing treatment pipe 3, and the two groups of spray racks cooperate with each other to perform multi-stage treatment on the exhaust gas, thereby improving the treatment effect of the exhaust gas, and a plurality of atomizing nozzles 10 are arranged at the bottom of the upper spray rack 8 and the lower spray rack 9, a rotating connector 12 is fixedly installed at the bottom of the lower spray rack 9, and one end of the rotating connector 12 is fixedly connected with a water guide pipe 18, and the water guide pipe 18 is connected to the lower spray rack 9 through the rotating connector 12, so as to ensure that the lower spray rack 9 is still in a connected state with the water guide pipe 18 when rotating, thereby realizing the upper The water passages of the spray rack 8 and the lower spray rack 9 are unobstructed. A transmission turbine 13 is fixedly installed on the top of the upper spray rack 8. The transmission turbine 13 is driven by the flowing exhaust gas to drive the upper spray rack 8 and the lower spray rack 9 to rotate, so that the water droplets sprayed after atomization by the atomizing nozzle 10 can fill the atomizing treatment pipe 3, avoiding the existence of a spray dead angle, so that the atomized water droplets can contact with the dust and harmful gases in the exhaust gas in all directions and fall. The upper spray rack 8 and the lower spray rack 9 are fixedly connected with a central pipe 11. A high-pressure water pump 17 is fixedly installed on the top of the paint booth body 1, and a water tank 19 is fixedly installed on the side. The water inlet of the high-pressure water pump 17 is fixedly connected to the water tank 19, and the water outlet is fixedly connected to the water guide pipe 18. The water is introduced into the two groups of spray racks along the water guide pipe 18 through the high-pressure water pump 17, and sprayed out along the atomizing nozzle 10 after being atomized, so as to treat the dust and harmful gases in the exhaust gas, so that the atomized water droplets can wrap the dust and harmful gases such as benzene and toluene in the exhaust gas for precipitation.

[0024] See also Figure 2 , 5 A mounting bracket 6 is clamped on the upper part of the inside of the atomizing treatment tube 3, and a center seat 7 is provided in the middle of the mounting bracket 6. The position of the center seat 7 is limited by the mounting bracket 6 to ensure the stability of the center seat 7 during operation. A connecting bearing is nested inside the center seat 7, and the center tube 11 is movably sleeved in the center seat 7 through the connecting bearing. The center tube 11 is restricted by the center seat 7 and then the upper spray frame 8 and the lower spray frame 9 to ensure that the upper spray frame 8 and the lower spray frame 9 are firmly installed inside the atomizing treatment tube 3, and the upper spray frame 8 and the lower spray frame 9 can rotate stably.

[0025] See also Figure 3 , 4The upper spray rack 8 and the lower spray rack 9 have the same structure. The atomizing nozzles 10 at the bottom of the upper spray rack 8 and the lower spray rack 9 are staggered. When the upper spray rack 8 and the lower spray rack 9 rotate, the atomizing nozzles 10 staggered at the bottom of the upper spray rack 8 and the lower spray rack 9 cooperate with each other, so that the atomized water droplets can fill the inside of the atomizing treatment pipe 3, so that the atomized water droplets can fully contact with the exhaust gas. The rotating connector 12 is located at the center of the atomizing treatment pipe 3. The rotating connector 12 connects the water pipe 18 with the lower spray frame 9 to ensure that the lower spray frame 9 is still in communication with the water pipe 18 when rotating, thereby achieving smooth water passages of the upper spray frame 8 and the lower spray frame 9. The upper spray frame 8 and the lower spray frame 9 are both on the central axis of the atomizing treatment pipe 3, ensuring that the upper spray frame 8 and the lower spray frame 9 can rotate stably inside the atomizing treatment pipe 3 to avoid interference between the upper spray frame 8, the lower spray frame 9 and the atomizing treatment pipe 3.

[0026] The connecting end 4 is designed to be narrowed from bottom to top, and the transmission turbine 13 is located inside the narrowed part of the connecting end 4. The transmission turbine 13 is driven by the exhaust gas to drive the upper spray frame 8 and the lower spray frame 9 to rotate, so that the water droplets sprayed after being atomized by the atomizing nozzle 10 can fill the atomizing treatment tube 3, avoiding the existence of dead corners of spraying, so that the atomized water droplets can contact with the dust and harmful gases in the exhaust gas in all directions and fall. The diameter value of the narrowed part of the connecting end 4 is one-third to one-fifth of the diameter value of the atomizing treatment tube 3. When the exhaust gas flows inside the connecting end 4, the flow rate of the exhaust gas inside the connecting end 4 can be increased, thereby ensuring that the exhaust gas can drive the transmission turbine 13 to rotate.

[0027] See also Figure 6 A filter cartridge 14 is provided at the bottom of the hollow connection seat 2, and a drainage end cap 15 is threadedly connected to the bottom end of the filter cartridge 14. In order to realize the controllable discharge of sewage inside the hollow connection seat 2, a control valve can be installed on the drainage end cap 15. When the exhaust gas is treated, the control valve is closed to prevent the exhaust gas from being discharged along the drainage end cap 15. A filter cotton 16 is clamped inside the filter cartridge 14. After the fallen water droplets enter the hollow connection seat 2, they can be filtered by the filter cotton 16 and then discharged along the drainage end cap 15. The bottom of the hollow connection seat 2 is a funnel structure, which can guide the water droplets entering the hollow connection seat 2. When discharging sewage, it is avoided that sewage is accumulated inside the hollow connection seat 2. The connection between the hollow connection seat 2 and the paint room body 1 is located above the funnel structure.

[0028] In summary, when the paint booth exhaust gas treatment water spray equipment is used, when the paint booth is working, the exhaust fan 5 is started to discharge the generated exhaust gas along the connecting end 4, the atomizing treatment pipe 3, and the hollow connecting seat 2, and the high-pressure water pump 17 is started. The high-pressure water pump 17 sucks the water in the water storage tank 19, and guides the water into the upper spray rack 8 and the lower spray rack 9 along the water guide pipe 18, and finally sprays the water along the atomizing nozzle 10 at the bottom of the upper spray rack 8 and the lower spray rack 9, so as to treat the dust and harmful gases in the exhaust gas. The atomized water droplets can wrap the dust and harmful gases such as benzene and toluene in the exhaust gas for sedimentation. After the exhaust gas enters the connecting end 4, the flow velocity increases. The fast-flowing exhaust gas drives the transmission turbine 13 to drive the upper spray frame 8 and the lower spray frame 9 to rotate, so that the water droplets sprayed after being atomized by the atomizing nozzle 10 can fill the atomizing treatment tube 3, so that the atomized water droplets can contact the dust and harmful gases in the exhaust gas in all directions and fall. After falling, the water droplets enter the hollow connecting seat 2, and the sewage is filtered by the filter cotton 16 and then discharged.
