Description

Technical Field

[0001] This utility model relates to the field of industrial exhaust gas purification technology, specifically an industrial exhaust gas purification spray washing device. Background Technology

[0002] Industrial exhaust gas purification spray scrubbing device is an environmental protection equipment that removes pollutants from industrial exhaust gas by fully contacting the spray scrubbing liquid (such as water, alkaline solution, etc.). It is widely used in chemical, metallurgical, power and other industries.

[0003] Existing patent document CN213853663U discloses an industrial exhaust gas purification spray scrubbing device, including a pipe flange, a connecting flange, a spray pipe, a nozzle connector, and a nozzle. The pipe flange is connected to the liquid inlet on the spray pipe located outside the scrubbing tower via a slip-fit. The connecting flange installed on the spray pipe outside the scrubbing tower is connected to the connecting flange on the scrubbing tower. A nozzle is detachably connected to the liquid outlet of the spray pipe located inside the scrubbing tower via the nozzle connector. The nozzle is used to spray and scrub the gas inside the scrubbing tower. This spray scrubbing device is a purification scrubbing spray gun that is not prone to clogging and is easy to unclog. During the cleaning process, only a few small parts need to be removed, making disassembly and cleaning convenient. At the same time, the nozzle structure has anti-clogging features, reducing nozzle replacement during use, greatly shortening maintenance and cleaning time, and improving the uptime of the equipment.

[0004] However, existing industrial exhaust gas purification spray scrubbing devices, while using atomizing nozzles to refine the scrubbing liquid into micron-sized droplets, remove pollutants from the gas through collisions between the droplets and the exhaust gas, suffer from problems when the spray head layout is unreasonable, such as excessive spacing or a single spray angle. This results in a small contact area between the exhaust gas and the scrubbing liquid, incomplete absorption of pollutants, and insufficient gas-liquid contact, thus affecting the purification effect. To address this, we propose an industrial exhaust gas purification spray scrubbing device. Utility Model Content

[0014] (III) Beneficial Effects

[0015] This utility model provides an industrial exhaust gas purification spray washing device, which has the following beneficial effects:

[0016] (1) This industrial exhaust gas purification spray scrubbing device, through the setting of an inner spray ring, an outer spray ring, and a spray ring, when using the industrial exhaust gas purification spray scrubbing device, the operator starts the fan, the fan operation generates suction, the suction acts on the spray tower through the air extraction pipe, and the air inlet pipe can draw in the gas. When the gas enters the spray tower, the delivery pump draws in the washing liquid through the water extraction pipe, and the washing liquid is delivered to the first spray pipe and the second spray pipe through the delivery pipe respectively. The first spray pipe and the second spray pipe deliver the liquid to the inner spray ring and the spray ring respectively. At the same time, the spray ring ensures that the washing liquid flows completely within the spray ring through the water delivery pipe, and the spray ring sprays upwards. The shower head and the lower spray head atomize and spray the washing liquid. The washing liquid sprayed from the lower spray head can come into contact with the pollutants. At the same time, the upper spray head sprays the washing liquid upwards, allowing it to fall freely and come into contact with the exhaust gas. Meanwhile, the washing liquid in the inner spray ring is transported to the outer spray ring through the connecting pipe. The atomizing head on the inner spray ring atomizes the washing liquid and sprays it towards the center, while the atomizing head on the outer spray ring atomizes the washing liquid and sprays it outwards. This arrangement of spray heads is more reasonable and increases the contact area between the exhaust gas and the washing liquid, allowing the washing liquid to fully contact the exhaust gas and remove pollutants. Therefore, it improves the purification effect of the industrial exhaust gas purification spray washing device. Attached Figure Description

[0023] Please see Figure 1-4 This utility model provides a technical solution: an industrial exhaust gas purification spray washing device, including a spray tower 1. A water pumping pipe 6, a first spray pipe 7, and a second spray pipe 8 are threadedly connected to one side of the spray tower 1. A delivery pump 9 is installed at one end of the water pumping pipe 6. A spray ring 17 is installed at one end of the first spray pipe 7. A water supply pipe 18 is threadedly connected to the inner side of the spray ring 17. An upper spray head 19 is threadedly connected to the top of the spray ring 17. A lower spray head 20 is threadedly connected to the bottom of the spray ring 17. An inner spray ring 13 is installed at one end of the second spray pipe 8. A connecting pipe 14 is threadedly connected to the top of the inner spray ring 13. An outer spray ring 15 is threadedly connected to one end of the connecting pipe 14. Atomizing heads 16 are threadedly connected to the inner side of the inner spray ring 13 and the outer side of the outer spray ring 15.

[0024] Furthermore, an air inlet pipe 2 and a water inlet pipe 3 are threadedly connected to the other side of the spray tower 1. A support leg 4 is welded to the outside of the spray tower 1. The exhaust gas can be better extracted through the air inlet pipe 2, and the washing liquid can be added into the spray tower 1 through the water inlet pipe 3.

[0025] Furthermore, the bottom of the spray tower 1 is threadedly connected to a filter cover 5, and the top of the filter cover 5 is fixedly connected to a filter element 501. A sealing ring 502 is installed on the top of the filter element 501. The washing liquid is filtered through the filter element 501, allowing the washing liquid to be reused. When the filter element 501 needs to be cleaned, the staff only needs to remove the filter cover 5 to take out the filter element 501 for cleaning.

[0026] Furthermore, a delivery pipe 901 is threadedly connected to one side of the delivery pump 9. The delivery pipe 901 is threadedly connected to the first spray pipe 7 and the second spray pipe 8 respectively. The washing liquid can be delivered to the first spray pipe 7 and the second spray pipe 8 respectively through the delivery pipe 901.

[0027] Furthermore, an exhaust pipe 10 is fixedly connected to the top of the spray tower 1. A fan 11 is bolted to one end of the exhaust pipe 10, and an exhaust pipe 12 is bolted to the top of the fan 11. By starting the fan 11, the fan 11 operates and generates suction. The suction is applied to the spray tower 1 through the exhaust pipe 10, and the air inlet pipe 2 can extract the gas.

[0028] Furthermore, a water collecting ring 101 is welded to the inner wall of the spray tower 1. The water collecting ring 101 is funnel-shaped and can collect the sprayed washing liquid and allow it to flow into the filter element 501.

[0029] Working Principle: After installation, first check the installation, fixation, and safety precautions of this utility model. When using the industrial exhaust gas purification spray washing device, the operator starts the fan 11. The fan 11 generates suction, which is applied to the spray tower 1 through the extraction pipe 10. The inlet pipe 2 draws in the gas. When the gas enters the spray tower 1, the delivery pump 9 draws in the washing liquid through the water extraction pipe 6. The washing liquid is delivered to the first spray pipe 7 and the second spray pipe 8 through the delivery pipe 901. The first spray pipe 7 and the second spray pipe 8 deliver the washing liquid to the inner spray ring 13 and the spray ring 17, respectively. At the same time, the washing liquid flows throughout the spray ring 17 through the water supply pipe 18. Simultaneously, the upper spray head 19 and the lower spray head 20 atomize and spray the washing liquid. The washing liquid sprayed from the lower spray head 20 can come into contact with the pollutants, while the upper spray head 19 sprays the washing liquid upwards, allowing it to fall freely and come into contact with the exhaust gas. At the same time, the washing liquid in the inner spray ring 13 is transported to the outer spray ring 15 through the connecting pipe 14. The atomizing head 16 on the inner spray ring 13 atomizes the washing liquid and sprays it towards the center, while the atomizing head 16 on the outer spray ring 15 atomizes the washing liquid and sprays it outwards. The sprayed washing liquid falls onto the water collection ring 101 and is filtered by the filter element 501, allowing the washing liquid to be reused. When the filter element 501 needs to be cleaned, the operator only needs to remove the filter cover 5 to take out the filter element 501 for cleaning. This completes the use of this utility model. This utility model has a simple structure and is safe and convenient to use.
