Description

Technical Field
The invention relates to the technical field of desulfurization and denitrification, in particular to a single-inlet single-outlet desulfurization and denitrification device based on water flow driving and capable of realizing swing spraying.
Background
In industrial processes, toxic and harmful industrial waste gases are often produced. If industrial waste gas is directly discharged into the atmosphere, the atmosphere is polluted, and the living environment of human beings is affected. Therefore, industrial waste gas generated in industrial production often needs to be purified before being discharged to the atmosphere. In the field of industrial waste gas purification treatment, desulfurization and denitrification treatment is one of the most common treatment methods. The wet desulfurization and denitrification method is the most common method for desulfurization and denitrification of industrial waste gas due to the characteristics of simple facility structure, low implementation cost and high desulfurization and denitrification rate.

In the existing wet desulfurization and denitrification equipment, a plurality of spray nozzles are distributed in an absorption tower in a planar manner. However, the position and direction of each spray opening are fixed, so the distribution range and the concentration distribution of the mist sprayed by the spray openings are also fixed. Therefore, the mist is not uniformly distributed, the desulfurization and denitrification reaction in some areas is insufficient, and even the waste gas in some areas is not subjected to the desulfurization and denitrification reaction completely, so that the desulfurization and denitrification effect is finally influenced.

Specifically, the desulfurization and denitrification equipment 10 that realizes swing spraying based on water flow driving with single inlet and single outlet further comprises a support frame 80 and a wastewater recovery tank 90. Wherein, the absorption tower 20 is arranged on the support frame 80, and the wastewater reclamation tank 90 is connected with the support frame 80. The waste water recovery tank 90 is arranged below the absorption tower 20, and the waste water recovery tank 90 is communicated with the reaction cavity 201; the wastewater recovery tank 90 is also in communication with a main waterway conduit 330.
The following is a description of the operation principle of the desulfurization and denitrification apparatus 10 with single inlet and single outlet and realizing swing spray based on water flow driving:
the water pump 320 pumps water from the wastewater collection tank 90 through the main water channel 330 and delivers the water to the water supply branch pipes 310 through the main water channel 330, respectively; when the water flow drawn from the wastewater reclamation tank 90 passes through the branch water supply pipe 310, the blade transmission member 200 is continuously impacted, and the swing driving device 50 drives the spray pipe 100 to swing back and forth by using the water flow passing through the branch water supply pipe 310 as a power source;
meanwhile, the water flow flows through the water supply branch pipe 310 and then is input into the spray pipe 100, and the water flow is atomized in the spray pipe 100 and then continuously sprayed into the reaction chamber 201 in the form of water mist; the spraying pipeline 100 is driven by the swing driving device 50 to continuously swing back and forth, so that the spraying pipeline 100 sprays water mist in the reaction chamber 201 in a swing spraying mode; the water mist is fully mixed with the industrial waste gas in the reaction cavity 201 and is subjected to desulfurization and denitrification reaction; the air changed into clean air through the desulfurization and denitrification reaction is discharged into the atmosphere through the waste gas outlet 60, and the water mist through the desulfurization and denitrification reaction slowly falls back to the bottom of the reaction chamber 201 and flows back to the wastewater recovery tank 90; the returned water mist is precipitated and purified in the wastewater recovery tank 90 to become clean water, and is supplied to the water supply device 30 again for recycling;
it should be noted that the spraying mode of the existing desulfurization and denitrification equipment is fixed spraying, and the water mist sprayed out of the spraying port cannot be completely uniform and consistent; therefore, some areas in the reaction chamber are inevitably not sprayed with water mist, or the water mist concentration of some areas is too high and the water mist concentration of some areas is too low, so that the water mist distribution is not uniform; therefore, in the process that the industrial waste gas rises from the bottom to the top of the reaction cavity, the desulfurization and denitrification reaction of the industrial waste gas in some areas is insufficient; according to the desulfurization and denitrification equipment 10 for realizing swing type spraying based on water flow driving, on one hand, the spraying width is larger, and the water mist sprayed to the reaction cavity is more uniform, so that the desulfurization and denitrification reaction of industrial waste gas is more sufficient, and the desulfurization and denitrification rate is further improved; on the other hand, the desulfurization and denitrification apparatus 10 for realizing the swing type spraying based on the water flow driving of the invention uses the water flow of the water supply branch pipe 310 as a driving source to realize the swing type spraying, and an additional driving device is not required to be added, so that the desulfurization and denitrification apparatus 10 has a simple and compact structure, and the system stability of the desulfurization and denitrification apparatus 10 is good;
here, the operation principle of the swing drive device 50 will be further explained: the water flow in the water supply branch pipe 310 continuously impacts the blade transmission member 200 and causes the blade transmission member 200 to continuously rotate; in the process that the blade transmission member 200 continuously rotates, the driving connection end 500 of the transmission eccentric connecting rod 300 is driven to continuously rotate in a gear meshing mode, and then the eccentric swing action end 600 of the transmission eccentric connecting rod 300 is indirectly driven to continuously rotate; in the process that the eccentric swing action end 600 continuously rotates, the eccentric swing action end 600 repeatedly abuts against the side wall of the swing matching groove 70 or is separated from the side wall of the swing matching groove 70, so that the sealing bearing 400 swings in a reciprocating manner within a certain angle range, and the spraying pipeline 100 is indirectly driven to swing in a reciprocating manner within a certain angle range; the spraying pipeline 100 continuously sprays while swinging in a reciprocating manner within a certain angle range, namely dynamic spraying is realized; this allows the spray area of the spray opening 110 to be larger, which in turn allows the spray device 40 to spray more evenly; therefore, the desulfurization and denitrification reaction of the industrial waste gas is more uniform and more sufficient, the waste of resources is avoided, and the desulfurization and denitrification rate is further improved.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
