Description

Technical Field

[0001] The utility model belongs to the technical field of scrubbers, and particularly relates to an efficient flue gas purification scrubber. Background Technique

[0002] The flue gas purification scrubber is a new type of gas purification and treatment equipment, mainly used to treat harmful gases in industrial waste gas, such as sulfur dioxide, nitrogen oxides, chlorine gas, etc. If these harmful gases are discharged without treatment, they will cause harm to the environment and human health. In the prior art, the waste gas discharged from the flue gas purification scrubber contains a certain amount of atomized spray liquid components because it contacts the spray liquid. These components are not treated and are directly discharged, which not only causes a certain degree of waste, but also makes the flue gas still have a certain degree of harmfulness. Content of the Utility Model

[0003] Aiming at the above problems, the purpose of the utility model is to provide an efficient flue gas purification scrubber, which not only avoids the harmful components in the spray liquid in the discharged flue gas, but also can recycle this part of the spray liquid, playing a role in saving the spray liquid.

[0004] To achieve the above purpose, the utility model provides the following technical solution: An efficient flue gas purification scrubber, including a bottom assembly section, a middle assembly section is provided at the top of the bottom assembly section, a top assembly section is provided at the top of the middle assembly section, support seats are provided inside the middle assembly section and the top assembly section, a packing installation frame is supported and installed on the top of the support seat, a packing filling frame is inserted and installed inside the packing installation frame, a liquid storage tank is provided inside the bottom assembly section, a spray liquid relay bin is provided on the side of the bottom assembly section, a spray mechanism is installed at the top of the spray liquid relay bin, a screw connection plate is screwed to the bottom of the support seat, a dust-blocking L-shaped angle plate is installed at the bottom of the screw connection plate, an air inlet pipe is connected to the side of the bottom assembly section, an exhaust pipe is connected to the top of the top assembly section, one end of the exhaust pipe is connected to a shunt plate, the bottom of the shunt plate is connected to a combined spiral condensing pipe, the bottom of the combined spiral condensing pipe is connected to a confluence plate, the bottom of the confluence plate is connected to a V-shaped pipe, the bottom of the V-shaped pipe is connected to a return pipe, the bottom end of the return pipe is connected to a spray liquid return storage tank through a hose, and heat-conducting sheets are provided on the outside of the combined spiral condensing pipe.

[0005] The beneficial effect of the utility model is that the device is provided with a screw connection plate and a dust-blocking L-shaped angle plate. Through the combination of multiple groups of screw connection plates and dust-blocking L-shaped angle plates, the particles in the flue gas can be blocked to a certain extent during the rising process of the flue gas, and the rising speed of the flue gas can be delayed, thereby playing a role in further improving the flue gas purification effect.

[0006] The purified flue gas is discharged from the spray tower through the exhaust pipe and enters the shunt plate, where it is shunted into each combined spiral condenser. A large number of heat conducting fins are sleeved outside the combined spiral condenser. The heat in the high-temperature flue gas in the combined spiral condenser can be quickly and efficiently exchanged to the external air through the heat conducting fins. Moreover, since the combined spiral condenser is spiral in shape, the flow path of the flue gas in the combined spiral condenser is extended, that is, the cooling time of the flue gas in the combined spiral condenser is extended, so as to effectively condense the spray liquid droplets doped in the flue gas due to contact with the spray liquid. These condensed spray liquid droplets can flow back into the spray liquid reflux storage tank through the reflux pipe at the bottom of the V-shaped pipe, and can flow back into the spray liquid relay bin through the spray liquid reflux storage tank for reuse. This not only avoids the harmful components in the spray liquid contained in the discharged flue gas, but also can recycle this part of the spray liquid, playing a role in saving the spray liquid.

[0007] The packing of this device is filled in the packing filling frame. Stainless steel meshes are provided at the top and bottom of the packing filling frame, which play a role in supporting the packing and preventing it from leaking. When the packing needs to be replaced, only need to use the lifting ring to lift the packing filling frame out of the inside of the packing installation frame, and move it out and lower it through the manholes on the side of the middle assembly section and the top assembly section, which is convenient for the quick replacement of the packing.

[0008] In order to support the packing filling frame:

[0009] As a further improvement of the above technical solution: a bottom bracket is provided inside the packing installation frame.

[0010] The beneficial effect of this improvement is that the bottom bracket is used to support the packing filling frame.

Stainless steel meshes are provided at the top and bottom of the packing filling frame, which play a role in supporting the packing and preventing it from leaking. When the packing needs to be replaced, only need to use the lifting ring to lift the packing filling frame out of the inside of the packing installation frame, and move it out and lower it through the manholes on the side of the middle assembly section and the top assembly section, which is convenient for the quick replacement of the packing.

[0014] In order to avoid blockage of the conveying pipe and the spray pipe:

[0015] As a further improvement of the above technical solution: a filter element is provided inside the spray liquid relay bin.

[0016] The beneficial effects of this improvement are as follows: The filter element is used to filter out impurities in the spraying liquid, preventing the conveying pipe and the spraying pipe from being blocked.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0033] like Figure 1-7 As shown, a high-efficiency flue gas purification washing tower comprises a bottom assembly section 1, a middle assembly section 2 is arranged on the top of the bottom assembly section 1, a top assembly section 3 is arranged on the top of the middle assembly section 2, a support seat 4 is arranged inside the middle assembly section 2 and the top assembly section 3, a packing installation frame 5 is supported and installed on the top of the support seat 4, a packing filling frame 7 is inserted and installed inside the packing installation frame 5, a liquid storage tank 10 is arranged inside the bottom assembly section 1, a spray liquid relay bin 11 is arranged on the side of the bottom assembly section 1, a spray mechanism is installed on the top of the spray liquid relay bin 11, a screw plate 17 is screwed on the bottom of the support seat 4, and the A dust-blocking L-shaped angle plate 16 is installed at the bottom of the screw plate 17, an air intake pipe 18 is connected to the side of the bottom assembly section 1, and an exhaust pipe 19 is connected to the top of the top assembly section 3. One end of the exhaust pipe 19 is connected to a diverter plate 20, and the bottom of the diverter plate 20 is connected to a combined spiral condenser 21. The bottom of the combined spiral condenser 21 is connected to a merging plate 22, and the bottom of the merging plate 22 is connected to a V-shaped pipe 23. The bottom of the V-shaped pipe 23 is connected to a reflux pipe 24, and the bottom end of the reflux pipe 24 is connected to a spray liquid reflux storage tank 25 through a hose. A heat conductive sheet 26 is provided on the outside of the combined spiral condenser 21.

[0034] The device is provided with a screw plate 17 and a dust-blocking L-shaped angle plate 16. Through the combination of multiple sets of screw plates 17 and dust-blocking L-shaped angle plates 16, the particles in the smoke can be blocked to a certain extent during the smoke rising process, and the smoke rising speed can be slowed down, thereby further improving the smoke purification effect.

[0035] The purified flue gas is discharged from the spray tower through the exhaust pipe 19 and enters the shunt plate 20, where it is shunted into each combined spiral condenser tube 21. A large number of heat conducting fins 26 are sleeved outside the combined spiral condenser tube 21. The heat in the high-temperature flue gas in the combined spiral condenser tube 21 can be quickly and efficiently exchanged to the outside air through the heat conducting fins 26. And since the combined spiral condenser tube 21 is spiral-shaped, the flow path of the flue gas in the combined spiral condenser tube 21 is extended, that is, the cooling time of the flue gas in the combined spiral condenser tube 21 is extended, thereby effectively condensing the spray liquid droplets doped in the flue gas due to contact with the spray liquid. These condensed spray liquid droplets can flow back into the spray liquid reflux storage tank 25 through the reflux pipe 24 at the bottom of the V-shaped pipe and can flow back into the spray liquid relay bin 11 through the spray liquid reflux storage tank 25 for reuse. This not only avoids the harmful components in the spray liquid from being contained in the discharged flue gas, but also can recycle this part of the spray liquid, playing a role in saving the spray liquid.

[0036] The packing of this device is filled in the packing filling frame 7. Stainless steel meshes 8 are provided at both the top and bottom of the packing filling frame 7, which play a role in supporting the packing and preventing it from leaking. When the packing needs to be replaced, only need to use the lifting ring 9 to lift the packing filling frame 7 out of the inside of the packing installation frame 5, and move it out and lower it through the manholes on the sides of the middle assembly section 2 and the top assembly section 3, which is convenient for the quick replacement of the packing.

[0037] A bottom bracket 6 is provided inside the packing installation frame 5.

[0038] The bottom bracket 6 is used to support the packing filling frame 7.

[0039] Stainless steel meshes 8 are provided at both the top and bottom of the packing filling frame 7. The inside of the packing filling frame 7 is filled with packing, and a lifting ring 9 is provided at the top of the packing filling frame 7.

[0040] The packing of this device is filled in the packing filling frame 7. Stainless steel meshes 8 are provided at both the top and bottom of the packing filling frame 7, which play a role in supporting the packing and preventing it from leaking. When the packing needs to be replaced, only need to use the lifting ring 9 to lift the packing filling frame 7 out of the inside of the packing installation frame 5, and move it out and lower it through the manholes on the sides of the middle assembly section 2 and the top assembly section 3, which is convenient for the quick replacement of the packing.

[0041] A filter element 12 is provided inside the spray liquid relay bin 11.

[0042] The filter element 12 is used to filter out impurities in the spray liquid to avoid blockage of the conveying pipe 14 and the spray pipe 15.

[0043] The spray liquid relay bin 11 is connected to the bottom assembly section 1 through a pipeline, and the side of the spray liquid reflux storage tank 25 is connected to the spray liquid relay bin 11 through a pipeline.

[0044] The spray liquid in the spray liquid reflux storage tank 25 and the spray liquid relay bin 11 can enter the spray liquid relay bin 11 and be pumped out for spraying through the spray pump 13.

[0045] The spray mechanism includes a spray pump 13. One end of the spray pump 13 is connected to a delivery pipe 14, and the delivery pipe 14 is connected to a spray pipe 15.

[0046] The spray liquid in the liquid storage tank 10 can flow into the spray liquid relay bin 11, be filtered by a filter element 12, pumped into the delivery pipe 14 by the spray pump 13, and evenly sprayed downward through the spray pipe 15.

[0047] Working principle and usage process of the utility model: When the device is in use, the flue gas is input into the interior of the bottom assembly section 1 through the intake pipe 18 and then flows upward. The spray liquid in the liquid storage tank 10 can flow into the spray liquid relay bin 11, and after being filtered by the filter element 12, it can be pumped into the delivery pipe 14 by the spray pump 13 and uniformly sprayed downward through the spray pipe 15. The spray liquid is sprayed onto the packing, and a large amount of spray liquid adheres to the surface of the packing. By increasing the contact area between the spray liquid and the flue gas through the surface of the packing, the reaction effect between the flue gas and the spray liquid is improved. At the same time, the packing, through its pores and uneven surface, also has a good adsorption effect on the dust in the flue gas. By adsorbing the particles in the flue gas with the spray liquid and absorbing the harmful components therein, combined with the improvement of the reaction effect between the spray liquid and the flue gas by the packing and its own adsorption effect on the particles in the flue gas, the effect of purifying the flue gas is achieved. The device is also provided with a screwed plate 17 and a dust-blocking L-shaped angle plate 16. Through the combination of multiple groups of the combination of the screwed plate 17 and the dust-blocking L-shaped angle plate 16, the particles in the flue gas can be blocked to a certain extent during the upward flow of the flue gas, and the upward flow speed of the flue gas can be delayed, thereby playing a role in further improving the flue gas purification effect. The spray liquid sprayed out by the spray pipe 15 returns to the spray liquid relay bin 11 for recycling after contacting, adsorbing, and reacting with the flue gas. The purified flue gas is discharged from the spray tower through the exhaust pipe 19 and enters the shunt plate 20, and is shunted into each combined spiral condenser tube 21. A large number of heat-conducting fins 26 are sleeved outside the combined spiral condenser tube 21. The heat in the high-temperature flue gas in the combined spiral condenser tube 21 can be quickly and efficiently exchanged to the external air through the heat-conducting fins 26. And because the combined spiral condenser tube 21 is in a spiral shape, the flow path of the flue gas in the combined spiral condenser tube 21 is extended, that is, the cooling time of the flue gas in the combined spiral condenser tube 21 is extended, so as to effectively condense the spray liquid droplets doped in the flue gas due to contact with the spray liquid. These condensed spray liquid droplets can flow back into the spray liquid reflux storage tank 25 through the return pipe 24 at the bottom of the V-shaped pipe and can flow back into the spray liquid relay bin 11 through the spray liquid reflux storage tank 25 for reuse. This not only avoids the harmful components in the spray liquid from being contained in the discharged flue gas, but also can recycle this part of the spray liquid, playing a role in saving the spray liquid. The packing of the device is filled in the packing filling frame 7. Stainless steel meshes 8 are provided at the top and bottom of the packing filling frame 7, playing a role in supporting the packing and preventing it from leaking. When the packing needs to be replaced, only need to use the lifting ring 9 to lift the packing filling frame 7 out of the interior of the packing installation frame 5, and move it out and lower it through the manholes on the sides of the middle assembly section 2 and the top assembly section 3, which is convenient for the quick replacement of the packing.
