Description

Technical Field

[0001] This utility model belongs to the field of desulfurization and denitrification technology, specifically relating to an integrated desulfurization, denitrification and dust removal device. Background Technology

[0002] The integrated desulfurization, denitrification, and dust removal unit is an integrated industrial waste gas treatment device, mainly used to simultaneously remove sulfur dioxide (SO2) and nitrogen oxides (NOx) from flue gas. x This system aims to achieve synergistic treatment of three pollutants: desulfurization, denitrification, and dust removal, including particulate matter and dust. Currently, integrated desulfurization, denitrification, and dust removal devices generally suffer from the following shortcomings:

[0003] When performing desulfurization, denitrification, and dust removal operations on flue gas, the traditional method involves spraying the desulfurization and denitrification liquid through horizontally placed nozzles to combine with the flue gas. However, the flue gas has less time to mix with the liquid as it flows vertically upwards, which reduces the overall efficiency of the desulfurization, denitrification, and dust removal device in treating the flue gas. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated desulfurization, denitrification and dust removal device, which aims to solve the problem in the prior art that the liquid used for desulfurization and denitrification is sprayed out through a horizontally placed nozzle and combined with the flue gas, while the flue gas has less time to mix with the liquid when it flows vertically upward.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An integrated desulfurization, denitrification, and dust removal device includes a treatment tower. A dust collection box is fixedly installed on the inner wall of the bottom end of the treatment tower. A first liquid storage tank is fixedly installed on the top end of the dust collection box. Two second liquid storage tanks are fixedly installed on the inner side wall of the treatment tower. A top umbrella is fixedly installed on the inner side wall of the two second liquid storage tanks. The bottom end of the top umbrella is connected to multiple connecting pipes. The bottom end of the multiple connecting pipes is connected to a bottom umbrella. An annular grid is fixedly installed on the outer side of the bottom umbrella. The outer side of the annular grid is fixedly connected to the inner side wall of the treatment tower. One of the second liquid storage tanks and the bottom end of the first liquid storage tank are connected to a liquid delivery pipe. The bottom end of the other second liquid storage tank is connected to multiple liquid collection pipes. The outer side of the multiple liquid collection pipes is interlaced with the inner side wall of the annular grid. A liquid extraction assembly is provided at the bottom of the bottom umbrella.

[0007] In a preferred embodiment of this invention, the liquid extraction assembly includes two liquid extraction rings fixedly installed on the inner side wall of the treatment tower. The bottom and top ends of the two liquid extraction rings are respectively connected to multiple top pipes and bottom pipes, and the top end of the top pipes is connected to the bottom end of the bottom pipes.

[0008] In a preferred embodiment of the present invention, the liquid extraction assembly further includes a first pipe and a second pipe that are respectively connected to the outer side of the liquid extraction ring. The outer side of the first pipe and the second pipe are fixedly connected to the inner side wall of the treatment tower. Two liquid extraction pumps are fixedly installed on the outer side of the treatment tower, and the two liquid extraction pumps are respectively connected to the first pipe and the second pipe.

[0009] As a preferred embodiment of this invention, both the top umbrella and the bottom umbrella have multiple spray holes at their bottoms.

[0010] In a preferred embodiment of this invention, an extension tube is fixedly installed at the top of one of the umbrellas.

[0011] As a preferred embodiment of this invention, a defogging grid is fixedly installed on the inner wall of the top of the processing tower.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) By setting two top umbrellas and a bottom umbrella, the flue gas can first flow from top to bottom through the bottom umbrella after dust removal. After passing through the annular grid, the flue gas flows from bottom to top through the top umbrella to the outlet. After flowing through the bottom umbrella and the top umbrella, the time between the flue gas and the desulfurization and denitrification liquid can be increased in a limited space, thereby improving the overall efficiency of the device in treating flue gas.

[0014] 2) The dust removal box can effectively remove dust from the flue gas through the liquid inside. In addition, the liquid extraction ring and bottom pipe can be used to recycle the liquid in the first liquid storage tank and one of the second liquid storage tanks, thereby improving the utilization rate of the liquid used for desulfurization and denitrification.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides the following technical solution: an integrated desulfurization, denitrification and dust removal device, including a treatment tower 1, a dust removal box 2 fixedly installed on the inner wall of the bottom end of the treatment tower 1, a first liquid storage tank 3 fixedly installed on the top end of the dust removal box 2, two second liquid storage tanks 4 fixedly installed on the inner side wall of the treatment tower 1, a top umbrella 5 fixedly installed on the inner side wall of the two second liquid storage tanks 4, a plurality of connecting pipes 51 connected to the bottom end of the top umbrella 5, a bottom umbrella 52 connected to the bottom end of the plurality of connecting pipes 51, an annular grid 53 fixedly installed on the outer side of the bottom umbrella 52, the outer side of the annular grid 53 fixedly connected to the inner side wall of the treatment tower 1, a liquid delivery pipe 6 connected to the bottom end of one of the second liquid storage tanks 4 and the first liquid storage tank 3, and a plurality of liquid collection pipes 41 connected to the bottom end of the other second liquid storage tank 4, the outer side of the plurality of liquid collection pipes 41 intersecting and communicating with the inner side wall of the annular grid 53, and a liquid extraction assembly 7 provided at the bottom of the bottom umbrella 52.

[0024] In practical use, the flue gas enters the dust collector 2 and is treated by the liquid inside the dust collector 2. At this time, the flue gas is output upward to the top of the bottom umbrella 52. The liquid to be sprayed inside the bottom umbrella 52 and the top umbrella 5 is drawn into the bottom umbrella 52 and the top umbrella 5 by the liquid extraction component 7 and sprayed downward. This allows the flue gas to mix with the liquid at the bottom umbrella 52 and continue to flow through the annular grid 53 to the top umbrella 5. The flue gas can then continue to mix with the flue gas through the liquid at the top umbrella 5, thus achieving desulfurization treatment of the flue gas. The treated flue gas continues to flow upward to the other bottom umbrella 52 for denitrification treatment, and is treated by the top umbrella 5 and the bottom umbrella 52 with the same function. This increases the mixing effect of liquid and flue gas in a limited space.

[0025] Preferably, the liquid extraction assembly 7 includes two liquid extraction rings 71 fixedly installed on the inner side wall of the treatment tower 1. The bottom and top ends of the two liquid extraction rings 71 are respectively connected to multiple top pipes 72 and bottom pipes 73. The top end of the top pipe 72 is connected to the bottom end of the bottom umbrella 52.

[0026] In practical use, when liquid needs to be sprayed downwards from both the top umbrella 5 and the bottom umbrella 52, the liquid inside the first liquid storage tank 3 or the second liquid storage tank 4 can be extracted through the bottom pipe 73. This allows the liquid to be input into the top pipe 72 through the liquid extraction ring 71, and then transported to the bottom umbrella 52 through the top pipe 72. The bottom umbrella 52 can then continue to transport the liquid into the top umbrella 5 through the connecting pipe 51, thereby improving the utilization rate of the liquid required for desulfurization and denitrification.

[0027] Preferably, the liquid extraction assembly 7 further includes a first pipe 74 and a second pipe 75 connected to the outside of the liquid extraction ring 71, the outside of the first pipe 74 and the second pipe 75 being fixedly connected to the inner wall of the processing tower 1, and two liquid extraction pumps 76 being fixedly installed on the outside of the processing tower 1, the two liquid extraction pumps 76 being connected to the first pipe 74 and the second pipe 75 respectively.

[0028] In practical use, when it is necessary to extract liquid from the first liquid storage tank 3 and the second liquid storage tank 4, the liquid pump 76 can be started, so that the bottom pipe 73 can concentrate the liquid to the lower half of the liquid extraction ring 71, and then flow to the position of the liquid pump 76 through the second pipe 75, so that the liquid pump 76 can continue to transport the liquid from the first pipe 74 to the upper half of the liquid extraction ring 71, and then transport the liquid into the bottom umbrella 52 through the top pipe 72.

[0029] Preferably, both the top umbrella 5 and the bottom umbrella 52 have multiple spray holes 54 at their bottoms.

[0030] In practical use, the liquid inside the top umbrella 5 and the bottom umbrella 52 can be sprayed downwards through the spray hole 54, so that the smoke and dust can be effectively mixed and contacted with the liquid when flowing.

[0031] Preferably, an extension tube 55 is fixedly installed at the top of one of the umbrellas 5.

[0032] In practical use, after the flue gas undergoes desulfurization through the first top umbrella 5, it can then flow to the upper part of the other bottom umbrella 52 through the extension pipe 55, thereby increasing the mixing effect between the flue gas and the liquid.

[0033] Preferably, a defogging grid 8 is fixedly installed on the inner wall of the top of the treatment tower 1.

[0034] In practical use, after the flue gas has been treated by desulfurization and denitrification, it can flow to the demisting grid 8 position to perform demisting treatment on the flue gas.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
