[0001] The invention relates to the technical field of flue gas desulfurization and denitrification, and in particular to a chimney opening type desulfurization and denitrification equipment. Background Art

[0002] The chimney opening type desulfurization and denitrification equipment is a kind of equipment used to treat sulfur dioxide and nitrogen oxides in flue gas. It is mainly used to reduce the pollution of flue gas emissions to the environment. The working principle of this equipment is to spray the slurry into the flue gas through a high-pressure spray head, and use the mixed contact of the slurry and the flue gas to achieve the effect of desulfurization and denitrification.

[0003] However, in the process of treating flue gas, when the flue gas contains a large amount of solid particles, treating the flue gas only by high-pressure spray will not only greatly increase the output of waste liquid, but also when the flue gas entering the desulfurization and denitrification equipment is greatly agitated, there will be insufficient contact between the flue gas and the slurry water mist, thereby reducing the purification efficiency of the flue gas.

When purifying the flue gas, the flue gas to be treated is discharged into the purification cylinder through the smoke inlet pipe, and the smoke exhaust fan is started. Under the action of the power of the smoke exhaust fan, the flue gas passes through the atomizing elbow and enters the atomizing groove in the special-shaped liquid carrier tray, so that the flue gas is mixed with the slurry in the atomizing groove. When the flue gas passes through the special-shaped liquid carrier tray and the atomizing elbow, the temperature carried by the flue gas will heat the special-shaped liquid carrier tray and the atomizing elbow, and as the flue gas combines with the slurry, a large amount of particulate matter contained in the flue gas will remain in the slurry in the special-shaped liquid carrier tray, and as the flue gas heats the slurry in the special-shaped carrier tray, a large amount of steam will be generated in the slurry and flow together with the flue gas, and the flue gas is roughly purified to remove a large amount of particulate matter in the flue gas;

As the flue gas combines with the slurry, a large amount of particulate matter contained in the flue gas will remain in the slurry in the special-shaped liquid carrier pan 7. As the flue gas heats the slurry in the special-shaped carrier pan, a large amount of steam will be generated in the slurry and flow along with the flue gas. By setting the atomizing elbow 8, the slurry in the atomizing groove can also be effectively prevented from flowing back.

[0061] As mentioned above, the concentrated waste liquid recovery sedimentation assembly 200 is provided with multiple groups, the concentrated waste liquid recovery sedimentation assembly 200 is arranged on the partition baffle 5, the concentrated waste liquid recovery sedimentation assembly 200 is connected with the special-shaped atomization generation carrier 100 and the filtrate box 4, the concentrated waste liquid recovery sedimentation assembly 200 includes a sedimentation box 9, a sedimentation pipe 10, a sedimentation valve 11, a concentrated liquid discharge pipe 12 and a concentrated liquid purification pipe 14, the sedimentation box 9 is arranged in the purification cylinder 1, the sedimentation pipe 10 is arranged on the partition baffle 5, and one end of the sedimentation pipe 10 It is connected to the special-shaped liquid-carrying plate 7, the other end of the sedimentation pipe 10 is connected to the sedimentation tank 9, the sedimentation valve 11 is installed on the sedimentation pipe 10, and the sedimentation valve 11 is located below the partition baffle 5.

[0063] As mentioned above, the dilute waste liquid recovery component 300 is arranged in the purification cylinder 1, the dilute waste liquid recovery component 300 is located above the special-shaped atomization generation carrier 100, the dilute waste liquid recovery component 300 is connected to the filtrate box 4, the dilute waste liquid recovery component 300 includes a dilute liquid collection plate 19, a conical gas dispersion hopper 20 and a dilute liquid discharge pipe 22, the dilute liquid collection plate 19 is sealed and arranged in the purification cylinder 1, the conical gas dispersion hopper 20 is connected and arranged on the dilute liquid collection plate 19, the conical gas dispersion hopper 20 is provided with a dispersion cover 21, and a plurality of dilute liquid discharge pipes 22 are provided, one end of the dilute liquid discharge pipe 22 is connected and arranged on the dilute liquid collection plate 19, and the other end of the dilute liquid discharge pipe 22 passes through the special-shaped liquid carrier plate 7 and the partition baffle 5 and is connected to the filtrate box 4.

[0066] A condensation plate 30 is further provided in the purification cylinder 1 , and the condensation plate 30 is located between the water circulation box 24 and the smoke exhaust fan 3 .

[0067] Specifically, the spray pump 29 is started, and the water in the membrane filter element 16 will enter the water circulation box 24 along the water circulation pipe 25, and the water in the water circulation box 24 will be pumped into the spray box 23 through the spray pump 29, so that the water in the spray box 23 will be sprayed out from the atomizing nozzle 27 through the spray pipe 26. The water sprayed from the atomizing nozzle 27 will contact with the flue gas containing a large amount of steam, and the flue gas will be purified twice. Compared with the traditional technology, the atomized water is combined with the dry gas, and the flue gas containing steam will fully contact with the atomized water. Combined with the above, a more complete purification of the flue gas can be achieved, and the moisture sprayed by the atomizing nozzle 27 will fall into the dilute liquid collection tray 19 and flow into the filtrate box 4 through the dilute liquid discharge pipe 22.

A water supply valve 32 is installed on each water supply pipe 31.

[0069] Specifically, before purifying the flue gas, slurry for adsorbing and purifying the flue gas is added to the special-shaped liquid carrier tray 7, the weak liquid collection tray 19 and the filtrate box 4 respectively through two water supply pipes 31, so that the slurry surface in the special-shaped liquid carrier tray 7 is above the bottom of the atomizing bent pipe 8, and as the slurry in the special-shaped liquid carrier tray 7 evaporates and the water content decreases, it can be continuously filled through the water supply pipe 31. As the water content in the weak liquid collection tray 19 continues to increase, the water in the filtrate box 4 can also be discharged by opening the filtrate valve 18.

[0070] Another implementation method is that when the flue gas content is low, but the temperature of the flue gas is high when it enters the purification cylinder 1, the water in the special-shaped liquid carrier plate 7 evaporates quickly, and the water in the filtrate box 4 has not reached saturation, when it is necessary to continuously fill the special-shaped liquid carrier plate with water, without filling water through the water supply pipe 31, the water in the thin liquid collection plate 19 can be increased so that the water level in the thin liquid collection plate 19 is above the conical diffuser head, and the water in the thin liquid collection plate 19 falls into the special-shaped liquid carrier plate 7 through the conical diffuser, thereby realizing the slurry replenishment of the special-shaped liquid carrier plate 7.
