[0028] As mentioned in the above background, the flue gas generated by the glass kiln in the production process must be treated by the flue gas desulfurization device before being discharged into the atmospheric environment. When the dry desulfurization device is used to treat the flue gas generated by the glass kiln, the desulfurizer (powder) in the desulfurization tower reacts with the sulfur ions in the flue gas to produce solid sulfide and precipitate into the ash bucket connected to the lower part of the desulfurization tower. During the chemical reaction process, there may be some desulfurizers that do not react with sulfur ions. This part of the desulfurizer will fall into the ash bucket with the solid (powder) sulfide to form residual desulfurizer, thereby reducing the effective utilization rate of the desulfurizer and increasing the production cost. Therefore, the inventors of the present application provide a flue gas desulfurization device for a glass kiln and a glass kiln in one or more embodiments. The flue gas desulfurization device disturbs the residual desulfurizer in the ash bucket by the pressure gas in the air pipe, and discharges the residual desulfurizer into the mixing chamber through the ash conveying pipe, and fully mixes the residual desulfurizer with the flue gas discharged from the glass kiln, and then enters the reaction chamber to react chemically, thereby realizing the reuse of the residual desulfurizer, saving the cost, and improving the effective utilization rate of the desulfurizer. Thus, one or more problems in the prior art are solved.

[0029] In view of the foregoing technical problems, the utility model provides a kind of flue gas desulfurization device for glass kiln, as shown in Figure 1 The utility model discloses a kind of flue gas desulfurization device for glass kiln, as shown in

[0030] Specifically, for example, a spray head (not shown in the figure) can be arranged on the top wall of the reaction chamber 1, and the powdered desulfurizer is sprayed into the reaction chamber 1 through the spray head, and chemically reacts with the flue gas discharged by the glass kiln in the reaction chamber 1 to displace the sulfur ions in the flue gas to form solid sulfides and precipitate in the ash bucket 2, thereby realizing the desulfurization treatment of the flue gas. During the desulfurization treatment process, part of the desulfurizer fails to chemically react with the sulfur ions, which will precipitate with the sulfides in the ash bucket 2 to form residual desulfurizer. The technical solution disclosed by the present application can realize the recycling of the residual desulfurizer by discharging a certain pressure gas into the gas pipe 8, and the pressure gas can disturb the residual desulfurizer in the ash bucket 2 connected to the gas pipe 8, and then the residual desulfurizer is discharged into the mixing chamber 6 through the ash conveying pipe 7, and is fully mixed with the flue gas discharged by the glass kiln, and then is discharged into the reaction chamber 1 to perform chemical reaction, thereby realizing the recycling of the residual desulfurizer. Specifically, the ash conveying pipe 7 is in communication with the mixing chamber 6 through a centrifugal fan (not shown in the figure), and the high-speed rotating blades of the centrifugal fan can suck the residual desulfurizer from the ash conveying pipe 7 into the mixing chamber 6, and then the residual desulfurizer is discharged into the mixing chamber 6 under the action of centrifugal force. In addition, although the ash (sulfides) in the ash bucket 2 will also be discharged into the mixing chamber 6 together with the residual desulfurizer, and then is precipitated in the ash bucket 2 again after being discharged into the reaction chamber 1, but the residual desulfurizer is recovered in the above process.

[0031] Compared with the prior art, the flue gas desulfurization device of the glass kiln disclosed by the present application can disturb the residual desulfurizer in the ash bucket 2 through the pressure gas in the gas pipe 8, and then the residual desulfurizer is discharged into the mixing chamber 6 through the ash conveying pipe 7, and is fully mixed with the flue gas discharged by the glass kiln, and then is discharged into the reaction chamber 1 to perform chemical reaction, thereby realizing the recycling of the residual desulfurizer, saving cost, and improving the effective utilization rate of the desulfurizer.

[0032] In some embodiments, as shown in Figure 1 the heat exchange chamber 9 is connected to the smoke outlet 5, and the gas pipe 8 passes through the heat exchange chamber 9 and is in communication with the ash bucket 2. Specifically, the flue gas discharged from the smoke outlet 5 has a certain temperature, and the heat exchange between the pressure gas in the gas pipe 8 and the flue gas is realized through the heat exchange chamber 9, thereby improving the temperature of the pressure gas, and further improving the temperature of the residual desulfurizer discharged into the mixing chamber 6, so that the residual desulfurizer can fully chemically react with the flue gas.

[0033] In some embodiments, as shown in Figure 1 the gas pipe 8 forms a spiral coil 10 in the heat exchange chamber 9. The spiral coil 10 can make the pressure gas fully exchange heat with the flue gas discharged from the smoke outlet 5, so as to improve the temperature of the pressure gas.

[0034] In some embodiments, the gas pipe 8 is coated with a heat preservation material (not shown in the figure). The heat preservation material can avoid heat loss of the pressure gas during transmission in the gas pipe 8.

[0035] In some embodiments, a filter screen (not shown in the figure) is arranged on the air inlet of the air pipe 8. Impurities in the pressure gas can be filtered through the filter screen to avoid its influence on the desulfurization process.

[0036] In some embodiments, a pressure sensor (not shown in the figure) is arranged on the air pipe 8 near one end of the ash conveying pipe 7. The pressure of the pressure gas in the air pipe 8 can be monitored in real time through the pressure sensor to ensure that the pressure of the pressure gas can disturb the residual desulfurizer and discharge it into the mixing chamber 6 through the ash conveying pipe 7.

[0037] In some embodiments, a desulfurizer concentration instrument (not shown in the figure) is arranged on the ash conveying pipe 7 near one end of the mixing chamber 6. The concentration of the residual desulfurizer discharged into the mixing chamber 6 can be detected in real time through the desulfurizer concentration instrument.

[0038] In some embodiments, a first on-off valve (not shown in the figure) is further arranged on the air inlet of the air pipe 8. The opening and closing of the air inlet of the air pipe 8 can be controlled through the first on-off valve, and the pressure of the pressure gas in the air pipe 8 can also be controlled by controlling the opening degree of the first on-off valve.

[0039] In some embodiments, a second on-off valve (not shown in the figure) is arranged on the ash conveying pipe 7. The opening and closing of the ash conveying pipe 7 can be controlled through the second on-off valve.

[0040] The utility model further provides a glass kiln, including above-mentioned glass kiln's flue gas desulfurization device.

[0041] In summary, compared with the prior art, the present disclosure provides a glass kiln flue gas desulfurization device and a glass kiln. The flue gas desulfurization device forms a disturbance to the residual desulfurizer in the ash bucket 2 through the pressure gas in the air pipe 8, and discharges the residual desulfurizer into the mixing chamber 6 through the ash conveying pipe 7. After the flue gas discharged by the glass kiln is fully mixed, it is discharged into the reaction chamber 1 for chemical reaction, thereby realizing the reuse of the residual desulfurizer, saving cost, and improving the effective utilization rate of the desulfurizer. The heat exchange between the pressure gas in the air pipe 8 and the flue gas is realized through the heat exchange chamber 9, thereby improving the temperature of the pressure gas. The pressure gas and the flue gas discharged from the smoke outlet 5 can be fully heat exchanged through the spiral coil 10.
