Description

Technical Field

[0001] This application relates to the technical field of glass furnace flue gas treatment devices, and more particularly to a glass furnace flue gas treatment device. Background Technology

[0002] Flue gas treatment equipment typically incorporates dust removal towers, denitrification towers, desulfurization towers, and degumming towers, depending on the environmental policies of the region where the plant is located. The denitrification tower generally employs SCR (Selective Catalytic Reduction) denitrification technology, and because its catalyst is ammonia water, it is also known as ammonia catalytic reduction denitrification. See the invention application with application number 202210029491.7 entitled "High-Cleanliness Desulfurization, Denitrification, and Dust Removal Device with Circulation Enhancement."

[0003] In some existing technologies, glass furnace flue gas can be discharged into the atmosphere after denitrification and dust removal reactions. However, the ammonia-catalyzed nitride reduction reaction has a certain temperature requirement (800-1050℃). If the flue is long or the denitrification tower is far from the flue outlet, the flue gas temperature may not reach this value. During the process modification, the introduction of a new type of electric flux suitable for borosilicate glass has led to a decrease in the temperature of the flame space inside the furnace. These factors make it difficult for the flue gas in the flue to reach the required reaction temperature. Conventionally, a denitrification tower with a heating device is used to solve this problem. However, this heating method is not internally controllable, and excessively high flue gas temperatures can significantly shorten the lifespan of the filter bags in the dust collector. The dust collector needs to operate at a temperature of 100-300℃, while the denitrification tower needs to operate at a high temperature of 800-1050℃. Furthermore, the uncontrollable flue gas temperature causes the two processes to interfere with each other, severely impacting the overall process. Utility Model Content

[0004] One of the technical problems this application aims to solve is that the temperature control effect of glass furnaces is not good when processing flue gas.

[0010] In some embodiments, the first connecting flue is made of 304 stainless steel.

[0011] In some embodiments, the flue gas heating assembly further includes a first temperature sensor, a second temperature sensor, and a third temperature sensor.

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0029] like Figures 1 to 3 As shown, the glass kiln flue gas treatment device of this embodiment includes: a flue assembly 10, a dust removal tower assembly 20, and a denitrification tower assembly. The flue assembly 10 includes a flue structure 11, a spray structure 12, and a collection structure 13. The spray structure 12 is disposed on the flue structure 11, and the collection structure 13 is disposed at the lower part of the flue structure 11. The outlet of the flue structure 11 is connected to the dust removal tower assembly 20. A flue gas heating assembly 30 includes a connecting flue 31 and a heating structure 32. The heating structure 32 is disposed on the connecting flue 31, and the inlet of the connecting flue 31 is connected to the dust removal tower assembly 20. The denitrification tower assembly is connected to the outlet of the connecting flue 31.

[0030] Through the above technical solution, the spray structure 12 provided in this application is installed inside the flue structure 11 to facilitate the collection and treatment of flue gas from the glass furnace. In addition to removing special impurities from the glass furnace, the spray structure 12 also serves to cool the gas, ensuring it reaches the temperature range required by the dust removal tower assembly 20. The flue gas heating assembly 30 heats the low-temperature flue gas after passing through the dust removal tower assembly 20, bringing it to the temperature treatment conditions required by the denitrification tower assembly 40. The technical solution of this embodiment effectively solves the problem of poor temperature control in glass furnaces during flue gas treatment in the prior art.

[0031] like Figure 1 and Figure 2As shown, in this embodiment, the flue structure 11 includes a horizontal main pipe 111, a vertical main pipe 112, and a horizontal branch pipe 113. The inlet of the horizontal main pipe 111 is connected to the glass furnace, the outlet of the horizontal main pipe 111 is connected to the inlet of the vertical main pipe 112, the outlet of the vertical main pipe 112 is connected to the collection structure 13, the inlet of the horizontal branch pipe 113 is connected between the inlet and outlet of the vertical main pipe 112, and the outlet of the horizontal branch pipe 113 is connected to the dust removal tower assembly 20. The spray structure 12 is located at the connection between the horizontal main pipe 111 and the vertical main pipe 112. The spray nozzles of the spray structure 12 face downwards, and the sprayed water is atomized water. A large amount of spray water is not required to effectively settle particles and other substances in the flue gas. This structure effectively utilizes gravity. Compared to the prior art where the spray structure is located inside the dust removal tower structure 21, it saves water and reduces the cost of wastewater treatment. It should be noted that the water used for spraying also needs to be temperature controlled. In this embodiment, water with a temperature of 15°C to 40°C is used for easy access.

[0032] like Figure 1 and Figure 2 As shown, in this embodiment, the collection structure 13 includes a collection chamber and a drawer. The top of the collection chamber has a first opening to communicate with the vertical main pipe 112, and the side wall of the collection chamber has a second opening. The drawer is movably installed in the collection chamber through the second opening. Depending on the source of the flue gas in this embodiment, the collection structure 13 differs from traditional collection structures, which only require a fluid outlet channel. Since this embodiment generates a large amount of poorly flowing condensate after cooling, this embodiment uses a method of removing the drawer to discharge the condensate after a certain amount has been collected. The drawer is a groove with an opening at the top, made of stainless steel. After the condensate falls into the drawer, the drawer is removed using a handle on the side wall of the drawer.

[0033] like Figure 1 and Figure 3 As shown, in this embodiment, the heating structure 32 includes a first heating structure 321, a second heating structure 322, and a third heating structure 323, which are spaced apart on the connecting flue 31. This staged heating structure allows the flue gas to be heated gradually, resulting in more uniform heating and easier control. Other heating methods could include four-stage or more heating structures, which will not be elaborated upon here.

[0034] like Figure 1 and Figure 3As shown in the technical solution of this embodiment, the flue gas heating assembly 30 further includes a heat insulation layer, which is disposed on the circumferential outer side of the connecting flue 31. The first heating structure 321, the second heating structure 322, and the third heating structure 323 are all disposed between the connecting flue 31 and the heat insulation layer. The fact that the first heating structure 321, the second heating structure 322, and the third heating structure 323 are all disposed on the circumferential outer side of the connecting flue 31 prevents substances in the flue gas from adhering to the heating structure 32, thus affecting the heating effect. Furthermore, the contaminants adhering to the heating structure 32 are difficult to clean. The heat insulation layer helps to reduce heat loss and save energy, and also ensures a more uniform temperature across the connecting flue 31, thereby guaranteeing a uniform flue gas temperature.

[0035] like Figure 3 As shown, in this embodiment, the connecting flue 31 is made of 304 stainless steel. Since flue gas is corrosive, this material results in a longer service life for the connecting flue 31. Furthermore, the aforementioned material provides good heat transfer, easily transferring heat from the external heating structure 32 to the interior of the connecting flue 31, thus facilitating a rise in flue gas temperature.

[0036] like Figure 3 As shown in the technical solution of this embodiment, the flue gas heating assembly 30 further includes a first temperature sensor 33, a second temperature sensor 34, and a third temperature sensor 35. The first temperature sensor 33 is disposed on the connecting flue duct 31 of the first heating structure 321 away from the second heating structure 322. The second temperature sensor 34 is disposed on the connecting flue duct 31 between the second heating structure 322 and the third heating structure 323. The third temperature sensor 35 is disposed on the connecting flue duct 31 of the third heating structure 323 on the side away from the second heating structure 322. The placement of the first temperature sensor 33, the second temperature sensor 34, and the third temperature sensor 35 facilitates the control of the flue gas temperature, making the flue gas control more precise. It should be noted that the first temperature sensor 33 extends into the interior of the connecting flue 31. The flue gas heating assembly 30 also includes a first protective cover, a second protective cover, and a third protective cover. The first protective cover covers the interior of the first temperature sensor 33 extending into the connecting flue 31. The first protective cover has an opening away from the direction from which the flue gas comes, and an arc-shaped plate facing the direction from which the flue gas comes. This reduces the adhesion of small amounts of particles and adhering substances in the flue gas to the first temperature sensor 33, extending its service life and improving temperature measurement accuracy. The second and third protective covers have the same structure as the first protective cover, and their installation structure is also the same as the first protective cover, so it will not be described again here.

[0037] like Figure 3As shown, in this embodiment, the flue gas heating assembly 30 further includes a first flamethrower structure 36 and a second flamethrower structure 37. The first flamethrower structure 36 is disposed on the connecting flue duct 31 between the first heating structure 321 and the second heating structure 322, and the second flamethrower structure 37 is disposed on the connecting flue duct 31 between the second heating structure 322 and the third heating structure 323. The first flamethrower structure 36 and the second flamethrower structure 37 can reduce the oxygen content in the flue gas.

[0038] like Figure 1 As shown, in this embodiment, the dust collector tower assembly 20 includes a dust collector tower structure 21 and a fan structure 22. The outlet of the horizontal branch pipe 113 is connected to the lower part of the dust collector tower structure 21, and the inlet of the flue is connected to the upper part of the dust collector tower structure 21. The fan structure 22 is located at the top of the dust collector tower structure 21. The fan structure 22 includes a motor and a fan. The fan is connected to the output shaft of the motor. The motor is located outside the dust collector tower structure 21, and the fan is located inside the dust collector tower structure 21. The fan agitates the gas inside the dust collector tower structure 21, thus improving the dust removal effect of the flue gas. It should be noted that the airflow blown by the fan flows downward, making it easier to remove dust particles under the action of gravity and gas flow. In this embodiment, the fan is relatively small, and the agitated airflow is relatively small.

[0039] In this embodiment, the glass furnace flue gas treatment device further includes a control component, which is electrically connected to the first heating structure 321, the second heating structure 322, the third heating structure 323, the first temperature sensor 33, the second temperature sensor 34, and the third temperature sensor 35. The control component includes a memory, a processor, and a display. First, a temperature threshold is set for the control component. When the control component receives the upper and lower temperature thresholds from the first temperature sensor 33, the second temperature sensor 34, and the third temperature sensor 35, it changes the heating power of the first heating structure 321, the second heating structure 322, and / or the third heating structure 323, respectively. This temperature control is time-saving, labor-saving, highly efficient, and precise. It should be noted that this application can also allow for manual adjustment, for example, by observing the temperatures of the first temperature sensor 33, the second temperature sensor 34, and the third temperature sensor 35, and adjusting the heating power of the first heating structure 321, the second heating structure 322, and the third heating structure 323 based on the observed temperatures.

[0040] In summary, the black arrows in the diagram indicate the direction of flue gas movement within the flue. The flue gas in the glass furnace travels along the horizontal flue section (horizontal main pipe 111) and, under the suction of the induced draft fan (not shown in the diagram), passes through the vertical flue (vertical main pipe 112). Above the vertical flue is a spray atomizing device (spray structure 12) that continuously sprays atomized cooling water. In practice, this method can cool the flue gas from approximately 700°C to around 200°C in a vertical flue approximately 10 meters long, effectively preventing damage to the dust collector bags from the flue gas.

[0041] Subsequently, the flue gas enters the dust removal tower (dust removal tower structure 21) through the horizontal flue. Through the combined action of three dust removal bags and the back blower (fan structure 22), the dust particles in the flue gas larger than the diameter of the bag holes are filtered onto the bags and then settled downwards by the back blower, and finally discharged through the ash discharge port.

[0042] The flue gas then enters the heating channel (connecting flue 31) of this invention. This heating channel is controlled by three thermocouples (temperature sensors), three heating copper busbars (heating structure 32), and two burners (first burner structure 36 and second burner structure 37). Let the temperature measured by the first temperature sensor be t1, the temperature measured by the second temperature sensor be t2, and the temperature measured by the third temperature sensor be t3. Then t3 is the target temperature. Using a medium-temperature denitrification catalyst with a reaction temperature of 500-650℃, the electrical operation method should be as follows: Assuming the set temperature of t1 is 150℃ and the temperature of t3 is 600℃, then the set temperature of t2 = (600-150)*0.75+150 = 487.5℃ (i.e., the temperature of the first temperature sensor 33 minus the temperature of the second temperature sensor 37) is t2. The 34th section is the main heating zone. The power of the two copper bars and the natural gas flow rate of the burner should be calculated using their respective electrothermal conversion ratios and calorific values ​​to obtain theoretical values. At the same time, the gas flow velocity in the flue, the diameter of the flue, and the horizontal and vertical lengths should be considered for fine-tuning. The three are calculated in parallel and controlled by a PID (proportional, integral, and derivative) system (collectively referred to as part of the control components). The relationship between the first and second temperature sensors is the same as above, but only one copper bar and one burner need to be considered. Meanwhile, the ratio of natural gas to oxygen in the burner can be 1:2.5 or directly 1:2 (because the kiln flue gas itself has a relatively high residual oxygen content, this ratio can consume the residual oxygen in the flue to a certain extent).

[0043] The metal flue section (connecting flue 31) is often made of 304 or other types of stainless steel. Since the kiln flue gas contains a large amount of boron oxide and its mixture, as well as a large amount of sulfur dioxide, these substances will cause severe corrosion to the metal under high temperature. It is generally believed that a metal is considered to be in a high-temperature working environment when its working temperature exceeds 30% of its melting point. Sulfur and boron are already very corrosive to metals at 600℃. Therefore, in order to minimize the corrosion of the metal flue, the area between the first temperature sensor 33 and the second temperature sensor 34 is designated as the main heating zone. The area between the second temperature sensor 34 and the third temperature sensor 353 only needs to ensure that the temperature of the flue gas reaches the required reaction temperature after passing through the copper busbar.
