[0002] The low-temperature flue gas desulfurization and dust removal device for glass kilns is a specially designed flue gas purification equipment for the low-temperature flue gas generated in the glass production process. Its main purpose is to remove sulfides and dust, reduce environmental pollution, and improve the cleanliness of the glass production process.

[0003] In the existing low-temperature flue gas desulfurization and dust removal device for glass kilns, the flue gas from the glass kiln enters the filter pipe, is filtered by the filter disc, and enters the smoke inlet pipe, and is introduced into the desulfurization barrel through the smoke inlet pipe, and is neutralized with the alkaline liquid in the barrel to achieve the purpose of flue gas desulfurization. At the same time, the output shaft of the servo motor will drive the filter disc to rotate, replace the filter position, and improve the filtering effect. While driving the filter disc to rotate, the servo motor will also drive the cam to rotate. When the protruding position of the cam is disengaged from the pressing frame, the spring pushes the pressing piece to move to the left to squeeze the knocking piece, so that the left part of the knocking piece is tilted. When the protruding position of the cam contacts the pressing piece, it will squeeze the pressing piece to reset the compression spring to the right, so that the torsion spring rebounds and drives the knocking piece to reset quickly, knocking the filter disc to remove dust, so that the filter disc can always be kept clean.

[0004] When knocking the ash, the purpose is to clear the dust accumulated on the filter plate, but in actual operation, some dust may be lifted and re-suspended, resulting in an increase in the dust concentration in the air, affecting the working environment, which is detrimental to the respiratory health of the operators, and may re-contaminate the purified flue gas and reduce the purification efficiency.

[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] In the specific implementation process, Figures 1 to 5 As shown, the low-temperature flue gas desulfurization and dust removal device for a glass kiln provided by the utility model comprises a desulfurization barrel 1, a smoke inlet pipe 2 is fixedly connected to the top of the desulfurization barrel 1, a connecting bracket 3 is fixedly connected to the outer wall of the smoke inlet pipe 2, and the side wall of the connecting bracket 3 is located on the top of the smoke inlet pipe 2 and is fixedly connected with a connected protective shell 5 and a filter pipe 4 in sequence from bottom to top;

[0024] A driving member is also fixedly connected to one side of the top of the desulfurization barrel 1. The output end of the driving member extends through the interior of the protective shell 5 and is fixedly connected to a filter disc 9. The filter tube 4 can be filtered by the filter disc 9 and passed into the smoke inlet pipe 2. The driving member can drive the filter disc 9 to rotate, thereby transferring the filtered part away and transferring the unfiltered part to between the smoke inlet pipe 2 and the filter tube 4. The filter disc 9 divides the interior of the protective shell 5 into a dust retention chamber 7 and a knocking chamber 6. A power member for knocking the filter disc 9 is provided in the dust retention chamber 7.

[0025] The device is first connected to the flue gas discharge port of the glass kiln through the smoke inlet pipe 2, and the smoke containing sulfur and dust is introduced into the system. The connecting bracket 3 on the outer wall of the smoke inlet pipe 2 ensures the stability of the structure and is easy to install and support. The smoke enters the protective shell 5. At this stage, the external environment is initially isolated to reduce external interference. The filter tube 4 further pre-filters larger particles to preliminarily purify the smoke. The driving member on the top of the desulfurization barrel 1 drives the filter disc 9 to rotate through the driving member. The smoke passes through the micropores of the filter disc 9, and fine particles are captured. The clean air flows through the filter disc into the smoke inlet pipe 2, and the unfiltered dust is retained between the filter disc and the filter tube 4. The dust accumulated in the dust chamber 7 is knocked off by the power member, collected and processed to avoid dust accumulation and blockage. At the same time, the protective shell 5 prevents the knocked dust from escaping to keep the environment clean.

[0026] Through the integrated design, it can both desulfurize and effectively filter dust for low-temperature flue gas to meet the needs of specific working conditions. The rotating filter disc 9 improves the filtering efficiency and operates continuously. The self-cleaning design reduces the maintenance cycle and improves the continuous operation capability of the system. The protective shell 5 and the dust retention chamber 7 are designed to close the knocking cleaning process, effectively controlling the dust from escaping and reducing environmental pollution.

[0027] The power member includes an oblique bracket 10 fixedly connected to the output end of the driving member and a fixed bracket 11 fixedly connected to the knocking cavity 6 of the protective shell 5, a knocking hammer 13 is rotatably connected to the fixed bracket 11, the top of the oblique bracket 10 is fitted with one side of the knocking hammer 13, the bottom of the knocking hammer 13 away from the end of the oblique bracket 10 is fitted with the top of the filter plate 9, and torsion springs 12 are fixedly connected between the two sides of the knocking hammer 13 and the fixed bracket 11, and the radial dimension of the end of the knocking hammer 13 fitted with the filter plate 9 is larger than the radial dimension of the knocking hammer 13;

[0028] The output end of the driving member is connected to the oblique bracket 10 to ensure the effective transmission of power. The oblique bracket 10 rotates to the top of the knocking hammer 13 and gradually lifts the knocking hammer 13 according to its own tilt angle. At this time, the torsion spring 12 generates a twisting force due to the rotation of the knocking hammer 13. When it is separated from the knocking hammer 13, the knocking hammer 13 can hammer the filter disc 9 at the bottom according to the gravity of the knocking hammer 13 and the torsion spring 12. The oblique bracket 10 knocks off the dust accumulated on the filter disc 9, so that the filter disc 9 is in a non-saturated state, which lays the foundation for subsequent continuous filtration.

[0029] The radial dimension of the fitting end of the knocking hammer 13 and the filter disc 9 is larger than its radial dimension, which means that when the knocking hammer 13 is knocking, the area of ​​the filter disc 9 covered by its bottom is larger than its own contact point, ensuring high efficiency of knocking and dust removal without missing any small parts, reducing ineffective knocking or damage to the filter disc.

[0030] The driving member includes a servo motor 8 and a mounting bracket, the mounting bracket is fixedly connected to one side of the top of the desulfurization barrel 1, the inner side wall of the mounting bracket is fixedly connected to the servo motor 8, the output end of the servo motor 8 is fixedly connected to the filter disc 9, the oblique bracket 10 is fixedly connected to the output end of the servo motor 8, and the oblique bracket 10 is located on the top of the filter disc 9;

[0031] The servo motor 8 is installed on the mounting bracket on the top of the desulfurization barrel 1, and is directly connected to the servo motor through the bracket, providing a precise and controllable rotational driving force for the entire cleaning mechanism. A filter disc 9 is directly fixed to the output end of the servo motor 8 to capture dust in the flue gas. Dynamic filtration and self-cleaning are achieved through the rotation of the servo motor 8.

[0032] The top of the smoke inlet pipe 2 extends through the dust retention cavity 7 of the protective shell 5 and fits with the bottom of the filter plate 9, and the bottom of the filter pipe 4 extends through the knocking cavity 6 of the protective shell 5 and fits with the top of the filter plate 9;

[0033] The top of the smoke inlet pipe 2 directly extends to the dust retention chamber 7 inside the protective shell 5, and fits with the bottom of the filter disc 9. The smoke first enters the flow through the smoke inlet pipe 2, and after initially entering the dust retention chamber 7, this design is conducive to the retention of large particles when entering. The bottom of the filter tube 4 then penetrates into the knocking chamber 6 of the protective shell 5 and fits with the top of the filter disc 9. The smoke preliminarily separated by the dust retention chamber further passes through the filter tube 4. At this time, the filter disc 9 performs more detailed filtration to ensure the cleanliness of the smoke. The dust retention chamber 7 and the knocking chamber 6 are designed separately. The former collects initially larger dust, and the latter acts on the filter disc 9 through the power parts during the knocking process, so that the dust accumulated on the filter disc is shaken to the bottom, which is conducive to collection or cleaning. The filter disc 9 is both a channel for the air flow path of the intake air and the key to cleaning. Through its rotation and knocking design, dynamic self-cleaning is achieved, maintenance requirements are reduced, and high efficiency is maintained.
