Problems solved by technology

However, when we check the exhaust gas treated by the acid mist absorption tower of the prior art, we often find that the pH range is acidic, which means that the acid mist absorption tower of the prior art does not treat the acid gas cleanly.
If the unclean gas is discharged directly, it will cause damage to the environment

Embodiment 1

[0034] see Figure 1-4 .

[0035] A spray ring 100, such as Figure 1-2 , which includes a spray ring pipe 11 connected to an external liquid supply device 21, the inner ring of the spray ring pipe 11 is provided with a plurality of spray heads 12, the spray heads 12 (such as image 3 ) is a duckbill nozzle 12, the nozzle hole 13 of the nozzle 12 is flat, and a blocking and direction changing plate 14 for changing the flow direction of the liquid mist is also provided in front of the nozzle hole 13.

[0036] As mentioned above, in this embodiment, the spray ring 100 can be installed in the external exhaust gas pipeline 22 for spraying the gas passing through the pipeline, specifically, the liquid mist in the spray ring 100 and the substances in the exhaust gas are For reaction purification, the spray ring pipe 11 is provided with a liquid inlet 16 that communicates with an external liquid supply device 21, and the treatment liquid in the liquid supply device 21 is a treatmen...

Embodiment 2

[0053] see Figure 1-4 .

[0054] An acid mist purification tower 200, any of the above spray rings 100, the spray ring 100 is installed at the air inlet 23.

[0055] As mentioned above, the spray ring 100 of the above-mentioned embodiment is installed in the air inlet 23 of the acid mist purification tower 200. Specifically, it can be understood that the spray ring 100 is installed in the exhaust pipe connected to the air inlet 23, so that the exhaust gas is It is purified once before entering the acid mist purification tower 200, which improves the efficiency of acid mist purification.

[0056] In this embodiment, the spray ring 100 is installed in the exhaust pipe 22 1.5-2.5 meters away from the air inlet 23 .

[0057] As mentioned above, the spray ring 100 is installed at a distance of 1.5 to 2.5 meters from the air inlet hole 23 because the treatment liquid sprayed by the spray ring 100 moves to the direction of the air inlet hole 23 under the action of the air flow. I...

Abstract

The invention discloses a spray ring. The spray ring comprises a spray ring pipe communicated with an external liquid supply device; a plurality of spray nozzles are arranged on an internal ring of the spray ring pipe; the spray nozzles are duck-billed spray nozzles; a spray hole of each spray nozzle is flat; a blocking direction changing plate is arranged in front of each spray hole, and is usedfor changing the flow direction of liquid mist. The spray ring can be arranged in an external exhaust gas pipeline; the spray ring pipe is communicated with an external processing liquid tank; liquidin the processing liquid tank is introduced into the spray ring pipe, and is sprayed out through the spray nozzles in the spray ring pipe, after direction guiding of the blocking direction changing plates, the liquid is sprayed to the ring internal direction of the spray ring pipe. The spray ring and an acid mist purifying tower provided with the spray ring can be used for pretreatment of exhaustgas; and especially in acid gas, complete purifying effect of exhaust gas processed using the spray ring and the acid mist purifying tower is achieved, and air purifying efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a spray ring and an acid mist purification tower. Background technique [0002] The production of electrolytic corrosion industry often uses acidic substances such as hydrochloric acid, nitric acid, and sulfuric acid, and hydrochloric acid, nitric acid, etc. have strong volatility. If the volatile gas is not treated in the production process, it will cause serious pollution to the atmospheric environment, and we often use The treatment method is to absorb acid gas with an acid mist absorption tower, and then neutralize it with sodium hydroxide. However, when we inspect the exhaust gas treated by the acid mist absorption tower of the prior art, we often find that the pH value is acidic, that is to say, the acid mist absorption tower of the prior art does not treat the acid gas cleanly. If the unclean gas is directly discharged, it will cause damage to t...
