Detailed implementation manners
[0028] Now, the present invention will be further described in detail with reference to the drawings.
[0029] Please refer to Figures 1 to 8 , the present invention provides a technical solution: an environmental protection filtration device for a lime kiln, including a bag dust collector, a cyclone separator 3, a cooling pipe 9 and a cooling box. An inlet dust pipe 2 is provided on one side of the bag dust collector. A cyclone separator 3 is connected by a pipeline to the upper end on one side of the bag dust collector. A remote controller 4 is provided outside the air outlet end of the cyclone separator 3. One side of the remote controller 4 is electrically connected to an air quality sensor 5 through a wire. The detection end of the air quality sensor 5 penetrates into the air outlet end of the cyclone separator 3.
[0030] A dust collecting hopper 6 is provided at the bottom of the bag filter. A dust discharging pipe 7 is provided at the bottom of the dust collecting hopper 6. An electromagnetic control valve 8 is provided in the middle of the dust discharging pipe 7. A plurality of cooling pipes 9 for cooling the high-temperature gas conveyed by the dust inlet pipe 2 are connected through the middle of the bag filter. The two ends of the cooling pipe 9 are respectively communicated with a liquid inlet pipe 10 and a liquid discharging pipe 11. The other ends of the plurality of liquid discharging pipes 11 all penetrate into the interior of the cooling box and are located inside the coolant cavity. The other ends of the plurality of liquid inlet pipes 10 are all communicated with the same multi-way pipe 12 at the upper end of the coolant tank. Considering that at present, in the rotary kiln lime production process, the bag filter is an important device for realizing environmental protection production. However, due to abnormal production conditions, the excessively high exhaust gas temperature is extremely likely to damage the bags of the bag filter. At the same time, the high-temperature ranges inside different bags are different. The traditional protection method is to manually adjust the cold air valve at the inlet of the bag filter according to the inlet temperature of the bag filter. The process is relatively cumbersome and requires a large amount of human resources. The utility model cools the high-temperature gas entering through the dust inlet pipe 2 of the device through the first temperature sensor 14, the second temperature sensor 16, the coolant tank, the coolant pipe and the coolant, avoiding damage to the dust removal bags inside the bag filter caused by the high-temperature gas. And the temperature of the high-temperature gas entering the interior of the bag filter can be obtained by using the second temperature sensor 16, so as to adjust the refrigeration temperature of the coolant by the temperature controller 15 for the semiconductor refrigeration sheet 20, so that the circulating coolant enters the coolant pipe and then the cooling pipe 9 releases low temperature to cool the high-temperature gas. And considering that after the coolant pipe is used for a long time, some dust falling due to the pulse of the pulse solenoid valve inside the bag filter will adhere to the surface of the coolant pipe. In the long run, the refrigeration effect of the coolant pipe will decrease. In view of this, the device will use the cleaning ring 28 to cooperate with the scraper 29 inside it to reciprocate along the coolant pipe under the drive of the multi-stage electric push rod 30. During this process, the dust adhering to the surface of the coolant pipe will be scraped off by the scraper 29, so as to ensure that the surface of the coolant pipe will not affect the refrigeration effect due to the adhesion of dust.
[0031] Wherein, the interior of the coolant tank is separated by a partition board into a driving cavity for installing the circulation pump 13 and a coolant cavity for storing the coolant. The negative pressure end of the circulation pump 13 penetrates through the partition board and is located inside the coolant cavity. And the output end of the circulation pump 13 is communicated with the liquid inlet end of the multi-way pipe 12 through a pipeline. By setting the circulation pump 13, the circulation pump 13 sends the coolant, and the coolant can be pumped into the coolant pipe. Then, the coolant that takes away the heat will return to the coolant cavity of the coolant tank again.
[0032] Among them, a first temperature sensor 14 is installed at the upper end of the partition plate. The detection end of the first temperature sensor 14 penetrates into the interior of the coolant chamber. The first temperature sensor 14 is connected to a temperature controller 15 on the surface of the coolant tank through a wire. The temperature controller 15 is also circuit-connected to a second temperature sensor 16 on one side of the bag filter through a wire. The temperature controller 15 is circuit-connected to a touch panel 17 on one side of the bag filter through a wire. By setting the second temperature sensor 16, it plays a role in detecting the temperature of the gas entering the bag filter from the dust inlet pipe 2. That is, after the detection end of the second temperature sensor 16 detects the temperature of the gas entering the bag filter, the temperature is transmitted to the touch panel 17, and then the touch panel 17 will control the circulating speed of the coolant pumped by the circulation pump 13 and adjust the release temperature of the thermoelectric cooler 20 through the temperature controller 15 according to the temperature.
[0033] Among them, a heat conduction plate 18 is installed on one side of the partition plate. A plurality of heat conduction rods 19 are arrayed at the bottom of the heat conduction plate 18, and each heat conduction rod 19 penetrates into the interior of the coolant chamber. The upper end of the heat conduction plate 18 is installed with a thermoelectric cooler 20 through thermal grease. The heating end of the thermoelectric cooler 20 is installed with a heat sink 21, and a plurality of cooling fans 22 are arranged above the heat sink 21. The plurality of cooling fans 22 are fixed to the heat conduction plate 18 through brackets. By setting the cooling fans 22, it plays a role in dissipating the temperature emitted from the heating end of the thermoelectric cooler 20.
[0034] Among them, a plurality of vibrating plates 23 are provided on the inner wall of the dust collection hopper 6. Each vibrating plate 23 and the dust collection hopper 6 are installed through a spring 24, and a dust-proof cover 25 is installed on the opposite surface of each vibrating plate 23 and the dust collection hopper 6. The upper ends of each vibrating plate 23 are symmetrically fixed with a chassis 26. A small vibrating motor 27 is provided inside each chassis 26. Considering that part of the dust entering the bag dust collector 1 is stored inside the dust storage bag and part will enter the dust collection hopper 6, the dust collection hopper 6 needs to be cleaned regularly. In this device, by turning on the switch of the small vibrating motor 27, then the small vibrating motor 27 starts up and generates vibration, so that the vibrating plate 23 vibrates, and thus the dust attached to the vibrating plate 23 and the inner wall of the dust collection hopper 6 is vibrated into the interior of the dust discharge pipe 7 for discharge.
[0035] Among them, a cleaning ring 28 is movably sleeved outside each coolant pipe, a scraper 29 for contacting the surface of the coolant pipe is fixed to the inner wall of each cleaning ring 28, a plurality of multi-stage electric push rods 30 are fixed outside the bag filter, and the telescopic end of each multi-stage electric push rod 30 is fixed to the side wall of the cleaning ring 28. A dust-proof telescopic sleeve 31 is sleeved outside the telescopic end of each multi-stage electric push rod 30, and both ends of each dust-proof telescopic sleeve 31 are fixed to the side wall of the bag filter and the side wall of the cleaning ring 28 respectively. By arranging the multi-stage electric push rods, the cleaning ring 28 is driven. When the driving ring is driven to move reciprocally along the coolant pipe, the scraper 29 on the inner wall of the cleaning ring 28 will scrape the dust on the surface of the coolant pipe and fall into the dust collection hopper 6.
[0036] The bag filter, cyclone separator and air quality sensor in this device are mature existing technologies, so the detailed working principle and model used are not described in detail in this article.
[0037] The present utility model is not limited to the above embodiments. Anyone should know that structural changes made under the inspiration of the present utility model, as long as they have the same or similar technical solutions as the present utility model, all fall within the protection scope of the present utility model. The technologies, shapes and structures not described in detail in the present utility model are all well-known technologies.
