DETAILED DESCRIPTION

[0023] In order for those skilled in the art to better understand the application, the technical solutions of the application are further described below in conjunction with the drawings and examples.

[0024] As shown in Figures 1-5 The waste gas treatment device for float method online production of low-emissivity film glass of the application includes a dustproof box 1, which adopts a sealed box body structure to provide a core space for waste gas treatment and effectively seal the dust overflow path. The dustproof box 1 is fixedly assembled with a partition 11 on the left and right sides inside the dustproof box 1. The dustproof box 1 is connected with an air outlet pipe 12 on the left upper end and an air inlet pipe 13 on the right upper end.

[0025] The two partitions 11 are each provided with a plurality of uniformly distributed through slots 14, and the through slots 14 on the left and right sides correspond to each other. The right partition 11 is fixedly assembled with a threaded ring 15, and the plurality of threaded rings 15 correspond one-to-one to the plurality of through slots 14. The plurality of threaded rings 15 are each assembled with a dust removal structure.

[0026] The threaded ring adopts a standardized interface design, which facilitates the quick installation and replacement of the dust removal bag, reduces the downtime maintenance time, and supports the adaptation of different specifications of filter bags through modular design, thereby enhancing the flexibility of the equipment.

[0027] The dust removal structure includes a mounting ring 16, which is threadedly connected with the threaded ring 15. The mounting ring 16 is fixedly assembled with a corrugated dust removal bag 161.

[0028] The corrugated structure significantly increases the filtering surface area and enhances the dust adsorption capacity, and is particularly suitable for capturing micrometer-sized particulate matter. When an antistatic material is used, the particulate matter adhesion can be further reduced, and the risk of blockage can be reduced.

[0029] The dustproof box 1 is fixedly assembled with a partition plate 17 in the middle. The plurality of through slots 14 on the upper and lower sides are circumferentially symmetrically distributed.

[0030] A plurality of support sleeves 171 are fixedly arranged in the middle of the dust removal box 1, a rotating shaft 172 is sealingly arranged in the support sleeves 171, rotating plates 173 are fixedly arranged on the front and back of the rotating shaft 172, a plurality of sealing plates 174 are fixedly arranged on the rotating plates 173, the plurality of sealing plates 174 are matched with the upper and lower distribution through grooves 14, a servo motor 175 is fixedly arranged at the right end of the dust removal box 1, and the output end of the servo motor 175 is in transmission connection with the rotating shaft 172.

[0031] The servo motor 175 drives the rotating shaft, drives the sealing plates to periodically open and close the through grooves, and realizes the function of blowing and ash removal in different areas. The design can remove the dust accumulated on the filter bag without interrupting the waste gas treatment, and improves the continuous operation capacity.

[0032] Maintenance doors 176 are sealingly arranged on the upper and lower sides of the front and back of the dust removal box 1.

[0033] The dust removal structure further comprises a fixed base plate 18, and a plurality of uniformly distributed support rods 181 are fixedly arranged between the fixed base plate 18 and the mounting ring 16. The filter bag is fixed by the uniformly distributed support rods 181, which can prevent the filter bag from being deformed or damaged due to air flow impact, and ensure long-term stable operation.

[0034] A plurality of support rods 181 are fixedly arranged together to form a support ring 182. The support ring 182 provides radial reinforcement to prevent the filter bag from collapsing and maintain the smoothness of the filter passage.

[0035] Flanges 19 are arranged on the upper ends of the air inlet pipe 13 and the air outlet pipe 12.

[0036] When the waste gas treatment device is in use, dust-containing waste gas enters the dust removal box 1 through the air inlet pipe 13, the waste gas enters the inside of the sealed box body, the right side partition plate 11 filters the air flow through the corrugated dust removal bag 161 fixed by the threaded ring 15, and then the waste gas enters the left side area through the through groove 14 of the partition plate 11. The rotating shaft 172 driven by the servo motor 175 periodically opens and closes the through groove 14 channel in linkage with the sealing plate 174, forming a regional blow-off air flow. This process uses compressed air to impact the surface of the filter bag in the opposite direction, peels off the accumulated dust without interrupting the filtration, and realizes continuous ash removal. Clean gas is discharged through the air outlet pipe 12, and the settled dust is guided to the dust collection area through the structure of the bottom support sleeve 171 and the rotating plate 173.

[0037] The key of the separated dust removal structure is the modular interface design: the standard interface of the threaded ring 15 allows the quick disassembly and assembly of the corrugated dust removal bag 161 by rotating the mounting ring 16, the radial reinforcement system composed of the support rod 181 and the support ring 182 maintains the stability of the filter bag shape under the impact of the airflow, and the bilateral symmetric layout of the maintenance door 176 matches the independent zoning configuration of the corrugated dust removal bag 161, so that the unilateral filter bag replacement does not need to shut down the whole machine. According to the characteristics of the silicate dust generated by the high-temperature combustion of the float glass, the device optimizes the filtering precision by adjusting the distribution density of the through slot 14 and the aperture gradient configuration of the filter bag, and at the same time, combines the servo motor to intelligently control the dust removal frequency, matches the dust load fluctuation, and ensures the dust removal efficiency under the continuous operation condition of the glass melting furnace.

[0038] The above embodiments only exemplarily illustrate the principles and effects of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the present application should be covered by the claims of the present application.
