Description

Technical Field

[0001] The utility model relates to a kiln dust removal device for producing glass, belonging to the technical field of glass production equipment. Background Art

[0002] During the kiln charging process, some raw materials fail to burn fully and are carried into the flue gas, resulting in dust in the flue gas. At the same time, volatile substances in the glass raw materials, such as Na2O and other metal oxides, gradually condense and form smoke dust during the high-temperature volatilization process.

[0003] A Chinese patent (CN 216986951 U) discloses a kiln for glass production, comprising a combustion kiln, an opening and closing door mounted on the front end of the combustion kiln, and a track fixed to the lower end of the combustion kiln. An air box is fixed to the upper end of the combustion kiln, an air pump is mounted on the upper end of the air box, a conduit is fixed to the output end of the air pump, a filter box is fixed to the extended end of the conduit, an activated carbon net is fixed to the upper end of the inner cavity of the air box, and slide bars are connected to the two sides of the lower end of the inner cavity of the air box through slotted sliding sleeves. In the present utility model, larger particles in the exhaust gas are filtered once through a multi-mesh filter, and smaller particles in the exhaust gas are filtered through an activated carbon net. The gas after the secondary filtration is then subjected to dust reduction through a circulating spray, which can effectively improve the filtering effect of the gas and prevent air pollution. By pulling the handle, the multi-mesh filter can be easily pulled out, and the cleaning brush can be used to clean impurities accumulated on the surface of the filter, which can be easily cleaned to prevent blockage.

[0004] The problems with the above patents are: (1) the gas generated in the combustion kiln is high-temperature gas, and the dust removal process does not recover the heat in the gas, so it is completely wasted; (2) the multi-mesh filter is flat in shape, and its contact area with the gas is limited, causing the multi-mesh filter to quickly accumulate dust, requiring frequent cleaning of the multi-mesh filter, resulting in reduced dust removal effect. Utility Model Content

[0005] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and provide a kiln dust removal device for producing glass, thereby improving the dust removal effect and the energy utilization efficiency.

[0006] The utility model discloses a dust removal device for a glass production furnace, comprising a fan, a conduit, a first filter assembly, a heat recovery assembly, and a second filter assembly. The first filter assembly, the heat recovery assembly, and the second filter assembly are sequentially connected in a horizontal direction. One end of the conduit is connected to the furnace through the fan, and the other end of the conduit is connected to the first filter assembly.

[0007] The first filter assembly includes a filter plate and a first filter box arranged in a vertical direction. The filter plate is placed in the first filter box. The filter plate is arranged in a wave shape. A plurality of filter holes are arranged on the filter plate. A conduit is arranged through the first filter box.

[0008] The heat recovery component includes a heat exchange water pipe and a heat exchange box. The heat exchange water pipe is placed in the box body in a spiral shape. Both ends of the heat exchange water pipe pass through the heat exchange box. The first filter box is connected to the heat exchange box.

[0009] A first spray mechanism is provided on the inner sidewall of the first filter box, corresponding to the filter plates. A first water outlet pipe is provided at the bottom of the first filter box, and a first valve is fixed to the first water outlet pipe. The first spray mechanism effectively cleans the filter plates, removing dust and particulate matter adhering to the filter plates, thereby maintaining filtration efficiency. The cleaning action of the first spray mechanism reduces damage to the filter plates caused by dust abrasion, thereby extending the service life of the filter plates. The first valve allows for convenient drainage of water from the filter box, facilitating cleaning of the filter box, removing accumulated dust and other impurities, and maintaining the cleanliness of the filter box and filtration efficiency.

[0010] The bottom of the first filter box is conical, which helps to concentrate and flow the water flow and reduce dead angles.

[0011] The heat exchange box is provided with dust collecting cotton. The dust collecting cotton can absorb fine particles and dust passing through the heat exchange box, further reducing environmental pollution. At the same time, the dust collecting cotton can prevent dust and particles from causing wear on the heat exchanger surface, thereby extending the service life of the heat exchanger.

[0012] The surface of the water exchange pipe is sprayed with an anti-corrosion material, which can effectively prevent the corrosive medium from eroding the base of the water exchange pipe and improve the corrosion resistance of the equipment.

[0013] A shock-absorbing mechanism is provided at the connection between the fan and the kiln. The shock-absorbing mechanism can effectively prevent the vibration of the fan from being transmitted to the kiln, thereby preventing the spread of the vibration source and reducing the impact of the vibration on the kiln structure.

[0014] The inner wall of the first filter box is provided with a slot, and the filter plate is placed in the slot. Through the slot design, the filter plate can be quickly installed and removed, which is convenient for regular replacement and cleaning, and improves maintenance efficiency.

[0015] The second filter assembly includes a second filter box, which is connected to the heat exchange box. A second spray mechanism is provided in the upper portion of the second filter box, and an air outlet duct is provided at the top of the second filter box. The spray mechanism provided in the top portion of the second filter box further cleans and purifies the air or flue gas after passing through the heat exchange box, effectively removing residual dust and particulate matter and improving overall filtration efficiency.

[0016] The second filter box is provided with a second outlet pipe at the bottom thereof, and a second valve is fixed on the second outlet pipe. The second valve can control the water flow in the second outlet pipe, thereby facilitating the adjustment of the water level in the second filter box and ensuring the filtering effect.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] By setting up a two-stage filter component, the dust emitted by the kiln can be captured and removed more effectively, improving the dust removal efficiency; the heat exchange water pipe in the heat recovery component absorbs the heat in the flue gas, so that the heat in the flue gas is recovered, thereby improving energy utilization efficiency; the filter plate is set in a wave shape, so that the filtration area of ​​a single filter plate is larger than that of a traditional flat filter plate, increasing the area in contact with the air, thereby improving the filtration efficiency.
