Description

Technical Field

[0001] This utility model relates to the field of integrated flue gas desulfurization and denitrification technology, specifically a reaction tower assembly with a built-in cooling structure. Background Technology

[0002] Large amounts of flue gas are often generated in the power, chemical, and metallurgical industries. These flue gases often contain a large number of toxic and harmful substances such as sulfides and nitrogen oxides. Direct emission into the air can cause environmental pollution. Therefore, the flue gas needs to be desulfurized and denitrified before it is emitted. Common flue gas treatment equipment includes flue gas reaction towers, flue gas scrubbing towers, absorption towers, absorption medium transmission pipelines, and flues.

[0003] Most common flue gas reaction towers use wet removal methods to desulfurize and denitrify flue gas. This requires transporting untreated flue gas into the reaction tower, where it reacts fully with the internal treatment liquid to achieve the purpose of desulfurization and denitrification.

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the prior art: 1. When using the reaction tower assembly to treat flue gas, the high temperature of the flue gas will cause insufficient reaction when reacting directly, which will reduce the desulfurization and denitrification effect of the flue gas; 2. Due to the high flow rate of the flue gas in the reaction tower assembly, it cannot fully react with the reaction liquid, which will reduce the efficiency of flue gas desulfurization and denitrification. Utility Model Content

To achieve the above objectives, this invention provides the following technical solution: a reaction tower assembly with a self-cooling structure, including a cooling mechanism, one end of which is inserted into a reaction mechanism, and an auxiliary mechanism is installed on the top of the reaction mechanism.

A denitrification liquid nozzle is installed at the bottom of the delivery pipe. A denitrification liquid outlet is connected to the lower side of the denitrification chamber.

[0008] The auxiliary mechanism includes an exhaust pipe with an auxiliary slot extending through one side. A filter plate is inserted into the auxiliary slot, a handle is welded to the outside of the filter plate, and a sealing ring is glued to the outer wall of the filter plate.

[0009] More preferably, the two ends of the gas supply pipe pass through the upper and lower ends of both sides of the cooling chamber, and the gas supply pipe inside the cooling chamber has a spiral structure.

[0010] More preferably, the spiral structure of the gas supply pipe is provided with a stirring shaft and stirring blades inside, and both ends of the circulating cooling pump are connected to circulation pipes, with the two circulation pipes respectively connected to the top and bottom of the cooling chamber.

[0011] More preferably, there are multiple flow deflectors, and one end of each flow deflector has a through groove, with the through grooves of two adjacent flow deflectors located at opposite ends of the flow deflectors.

[0012] More preferably, one end of the partition plate has a gas delivery groove, and the liquid blocking plate is vertically welded to one side of the gas delivery groove on the partition plate, and the liquid delivery pipe has a T-shaped structure, while the height of the liquid delivery pipe is the same as the height of the liquid blocking plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

At the same time, the stirring blades and circulating cooling pump in the cooling mechanism maintain the flow of cooling water in the cooling chamber, increase the contact effect between the gas pipeline and the cooling water, and further improve the cooling effect of the flue gas, thus avoiding the reduction of the desulfurization and denitrification effect of the flue gas when the high-temperature flue gas reacts directly.

[0016] In this invention, multiple sets of flow-blocking plates are set to obstruct the flow of desulfurization liquid, increasing the contact effect between flue gas and desulfurization liquid. Combined with denitrification liquid nozzles to spray denitrification liquid, the contact effect between flue gas and denitrification liquid is further improved, facilitating desulfurization and denitrification of flue gas, thereby improving the efficiency of desulfurization and denitrification operations of flue gas.

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a reaction tower assembly with a built-in cooling structure, including a cooling mechanism 1, one end of which is connected to a reaction mechanism 2, and an auxiliary mechanism 3 is installed on the top of the reaction mechanism 2.

[0024] The cooling mechanism 1 includes a cooling chamber 101, an air supply pipe 102 passing through the interior of the cooling chamber 101, a stirring motor 103 installed on the top of the cooling chamber 101, a stirring shaft 104 driven and connected below the stirring motor 103, stirring blades 105 welded to the outside of the stirring shaft 104, a circulation pipe 106 inserted into the outside of the cooling chamber 101, and a circulating cooling pump 107 inserted into one end of the circulation pipe 106.

[0025] The reaction mechanism 2 includes a reaction chamber 201, inside which is a desulfurization chamber 202. Inside the desulfurization chamber 202, a baffle plate 203 is installed. A desulfurization liquid inlet 204 is inserted into the upper side of the desulfurization chamber 202, and a desulfurization liquid outlet 205 is inserted into the lower side of the desulfurization chamber 202. A denitrification chamber 206 is installed at the top of the desulfurization chamber 202, and a partition plate 207 is installed at the bottom of the denitrification chamber 206. A liquid blocking plate 208 is welded to one end of the partition plate 207. A denitrification liquid pump 209 is installed on one side of the outer wall of the reaction chamber 201. A delivery pipe 2010 is inserted into one end of the denitrification liquid pump 209, and a denitrification liquid nozzle 2011 is installed at the bottom of the delivery pipe 2010. A denitrification liquid outlet 2012 is inserted into the lower side of the denitrification chamber 206.

[0026] The auxiliary mechanism 3 includes an exhaust pipe 301, an auxiliary slot 302 extending through one side of the exhaust pipe 301, a filter plate 303 inserted into the inside of the auxiliary slot 302, a handle 304 welded to the outside of the filter plate 303, and a sealing ring 305 glued to the outer wall of the filter plate 303.

[0027] In this embodiment, as Figure 1 and Figure 2 As shown, the two ends of the gas supply pipe 102 pass through the upper and lower ends of both sides of the cooling chamber 101, and the gas supply pipe 102 is located inside the cooling chamber 101 in a spiral structure; by setting the spiral gas supply pipe 102, the contact effect between the high temperature flue gas and the cooling water in the gas supply pipe 102 is improved, thereby improving the cooling effect of the high temperature flue gas.

[0028] In this embodiment, as Figure 1 and Figure 2 As shown, the spiral structure of the gas supply pipe 102 is equipped with a stirring shaft 104 and stirring blades 105. Both ends of the circulating cooling pump 107 are connected to circulation pipes 106, and the two circulation pipes 106 are respectively connected to the top and bottom of the cooling chamber 101. By setting the stirring structure, the circulation of cooling water in the cooling chamber 101 is accelerated, avoiding the accumulation of hot cooling water around the gas supply pipe 102 and affecting the cooling effect. The circulation pipes 106 further accelerate the flow of internal cooling water, thereby improving the cooling effect on high-temperature flue gas.

[0029] In this embodiment, as Figure 1 and Figure 3As shown, there are multiple baffle plates 203, and one end of each baffle plate 203 has a through groove. The through grooves of two adjacent baffle plates 203 are located at opposite ends of the baffle plate 203. By using multiple baffle plates 203 in conjunction with the through grooves, the flue gas transported to the desulfurization liquid is blocked, thereby increasing the contact effect between the flue gas and the desulfurization liquid and improving the desulfurization effect on the flue gas.

[0030] In this embodiment, as Figure 1 and Figure 3 As shown, a gas delivery groove runs through one end of the partition plate 207, and a liquid blocking plate 208 is vertically welded to one side of the gas delivery groove on the partition plate 207. The liquid delivery pipe 2010 has a T-shaped structure, and the height of the liquid delivery pipe 2010 is the same as the height of the liquid blocking plate 208. By setting a denitrification liquid nozzle 2011 to spray the denitrification liquid, the contact area between the flue gas and the denitrification liquid is increased, further improving the denitrification effect of the flue gas, thereby improving the efficiency of flue gas treatment.

[0031] In this embodiment, as Figure 1 and Figure 4 As shown, the filter plate 303 is connected to the inner wall of the exhaust pipe 301 by inserting into the auxiliary slot 302, and the sealing ring 305 is an annular arc structure. The sealing ring 305 is glued to the outer wall of the filter plate 303 and the outer wall of the auxiliary slot 302 to form a close connection structure. By setting the activated carbon filter plate 303 in the exhaust pipe 301, the flue gas is further denitrified. At the same time, the filter plate 303 is easy to disassemble and replace, which makes it easy to replace when needed, further improving the denitrification effect of the reaction tower assembly.

[0032] The method of use and advantages of this utility model: The reaction tower assembly with its own cooling structure operates as follows:

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, firstly, the stirring motor 103 is started, driving the stirring shaft 104 and stirring blades 105 in the cooling chamber 101 to rotate inside the spiral gas delivery pipe 102; then, the circulating cooling pump 107 is started, driving cooling water to circulate and cool in the circulating pipe 106, thus transporting the high-temperature flue gas to the reaction chamber 201 through the gas delivery pipe 102; next, the cooled flue gas enters the desulfurization chamber 202, at which time the desulfurization liquid enters the desulfurization chamber 202 through the desulfurization liquid inlet 204, and with the cooperation of the through groove in the baffle plate 203, the flue gas and the desulfurization liquid are fully mixed. The flue gas comes into contact with the desulfurized liquid and is discharged from the desulfurized liquid outlet 205. The flue gas treated by desulfurization enters the denitrification chamber 206 through the partition plate 207. The denitrification liquid pump 209 sprays the denitrification liquid from the delivery pipe 2010 through the denitrification liquid nozzle 2011 to fully react with the flue gas for denitrification treatment. Finally, the flue gas after reaction is filtered by the activated carbon filter plate 303 at the top and can be discharged through the exhaust pipe 301. When necessary, the filter plate 303 can be replaced by taking it out with the handle 304 and inserting it into the auxiliary slot 302.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
